    Simulation as an Enabler for ProductionSystem Development within the Indoor Vertical Farming Industry2023Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    With the increase in food consumption, new ideas, and technologies began to be developed. Inaddition, the developments generated by Industry 4.0 technologies have started to be applied tothe entire manufacturing sector and the indoor farming industry, which is currently trending.Many studies and articles have been prepared on this subject, and the main goal of each study isto produce quality products and to ensure continuity in production to cover the nonendingincrease in demand.

    This paper discusses how simulation technology, which is one of the industry 4.0 technologies,can be used in the production system development of the indoor farming industry. According tomany researchers, the biggest obstacle for the vertical farming industry is start-up cost, andsimulation technologies can be the solution for this since it allows future production systems tobe analyzed without any investment. To have a clear vision of how these technologies can beadapted in the indoor farming industry, this paper will find the answers to these questions, RQ1:How can simulation facilitate production system development and Industry 4.0 projects withinthe indoor farming industry? RQ2: What are the benefits and challenges when using simulationas a tool for production system development within the indoor farming industry? To reach thegoal of this paper, the case study method was used, and an indoor farming company was selectedto get more realistic data about the vertical farming system. BlueRedGold AB is a start-upcompany in the indoor farming industry, and it has a huge growth potential since they aim totransform its current production lines to be fully automated. Many articles and studies were usedto approach the solution of the research questions from a more technical and academic point ofview, and the analysis of these articles was carried out with the structured literature review method.

    After conducting this research, answers have been obtained for the research questions. Theauthors' solution to the layout issue, one of the case company's main challenges as indicated inthis study, was developed after extensive simulation model testing. As highlighted in this paper,it has been stated by many researchers, there are several simulation approaches to follow.However, the authors have developed a simulation modeling approach to be followed in theindoor vertical farming industry to overcome the complexity of these systems as well as thesimulation program complexity. In addition, several challenges and benefits have beenhighlighted in this paper such as the lack of ready models of the equipment used in indoorfarming which requires a knowledge of a programing language to overcome. Finally, despitechallenges, simulation technology can provide an applicable solution for production systemproblems of vertical farming companies/organizations to obtain continuous improvementphilosophy which is the main principle of Lean thinking. The generated simulation model in thisthesis project was successfully implemented, demonstrating how this technology might be aneffective solution for complex production systems as in the indoor farming sector.

    Proaktiva Produktnedläggningsbeslut: En Forskningsstudie om Utmaningar, Möjligheter och Effektiva Åtgärder inom Industriella Företagskontexter2024Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

     Produktnedläggningsbeslut kan gynna företag på flera områden, inklusive organisatoriska, ekonomiska och strategiska aspekter. Trots dessa fördelar uppstår utmaningar såsom bedömning av finansiell prestation, påverkan på intressenter och behovet av effektiv resursallokering. Detta gör beslutet mer komplext och krävande, vilket ofta möter motstånd från chefer. Trots ämnets vikt finns det en brist på forskning inom området. Av den anledningen undersöks vilka utmaningar, åtgärder och möjligheter som är förknippade med beslutet att lägga ned en produkt i denna studie. För denna studie användes en mixed-method approach, vilket innebar att både kvantitativa och kvalitativa metoder användes för att samla in empiriska data. Både en enkätundersökning och intervjuer med produktchefer inom industriföretag genomfördes för att möjliggöra en holistisk och omfattande undersökning av det studerade ämnesområdet. Den empiriska datan jämfördes sedan med den teori som sammanställts.  PNB kan medföra olika utmaningar relaterade till kunder, externa partners, strategi, ekonomi och organisation. För att hantera dessa utmaningar finns olika åtgärder som chefer inom industriella företag bör vidta, men den viktigaste av dessa är tydlig kommunikation. Det finns också möjligheter som detta beslut kan medföra. Genom att förstå dessa möjligheter kan företag skapa strategier för att maximera de positiva effekterna av PNB och stärka sin position på marknaden.

    Brainstorming VS Nominal group technique online: En jämförelse mellan idégenereringsmetoderna brainstorming och nominal group technique i en online miljö2020Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of this study can be separated into two purposes. The first purpose is to explore if the idea generation methods known as brainstorming and nominal group technique would give similar results depending on if the idea generating process was conducted in a physical space, compared to an online space. The second purpose of this study was to test both of the idea generating methods with a less lab focused situation, by asking a question that focuses on a real problem that the Company Coompanion, our partner in this study wanted answered. These purposes were tried in a workshop held with our partner Coompanion. Given the prevailing world situation in the spring of 2020, the experiment had to take on the form of a quasi-experiment where no control group could be created. The reason for this was the global pandemic and the government recommendation of not gathering in groups if it is avoidable, which led this study to compare with results obtained by a physical experiment made by Miller (2009). The results of the study indicates that the difference in the amount of generated ideas that normally exists between brainstorming and nominal group technique still exists. Although in contrast, the study shows that the total number of ideas from the online groups generated just a little more than half of the ideas compared to Millers (2009) physical groups. This indicates that idea generating online still doesn't measure up to a physical idea generating process. It was also shown that the ideas generated by the online nominal group technique group were more creative then the brainstorming group when it came to the question that Coompanion asked.

    Global Village: Ett utvecklingsarbete av konceptet Global Village utifrån co-creation perspektiv2023Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Oita University in Japan has created a meeting space called the Global Village that was inspired by Marshall McLuhan's (1962) theory that globalization contributes to an increased community between people from different parts of the world. It was created to increase interaction among students on campus and is intended for both international and local students. The vision for the place is for individuals to exchange information, knowledge, ideas, and cultures which promotes knowledge exchange and shared learning. However, the University of Oita faces a challenge regarding the Global Village as there is a lack of participation and interaction in the place. Which leads to the vision of Global Village not being fulfilled. The purpose of this thesis is to study how the students experience the Global Village. This was done to gain an understanding of how the place works and to develop ideas to improve the Global Village with the support of the co-creation perspective. Co-creation is about collaboration between individuals who could create some kind of value in the form of new ideas and solutions. Based on the problems identified in the study, the improvement ideas have been inspired by the co-creation theory to include in the Global Village at the university. The study was based on a qualitative approach to answer the research questions and there were several semi-structured interviews conducted with students from Oita University. The study found that open innovation has some factors that are important for developing the concept of the Global Village. And to make it a well-functioning co-creation space that provides value for the students. Those factors that were used within open innovation are networking and value creation, which were an inspiration to create a model. The different solution in the model is based on the problems that were identified in the Global Village. The model contains several different solution proposals to improve the Global Village at Oita University.

    Battery Connector - Examensarbete, Produktutveckling - konstruktion2013Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Examensarbetet är utfört inom produktutveckling – konstruktion och omfattar 15 högskolepoäng. Arbetet utfördes på halvtid under perioden januari – juni 2013. Examensarbetet utfördes för       OJOP Sweden AB i Eskilstuna av en student på Mälardalens Högskola. Examensarbetet startades den 6/1 – 2013 vid ett uppstartsmöte då uppdraget togs emot av OJOP Sweden AB´s ägare Anders Larsson. Uppdraget var att konstruera om eller konstruera en produkt med samma huvudegenskaper som företagets batterikontakt QuickPower. Detta för att reducera tillverkningskostnaderna som upplevdes för höga från företagets sida. Definitionen av problemet gjordes genom att undersöka den befintliga produkten och dess konkurrenter men också andra föremål som fäster på olika sätt. Undersökningarna resulterade i kunskap om hur problemet tidigare lösts och gav inspiration till en mängd idéer som bearbetades mentalt vilket ledde till skisser.  De olika skisserna sågs redan från början som potentiella koncept och redovisades för OJOP Sweden AB som fick utrymme att ge respons på koncepten. Ett koncept som innan redovisningen visat sig vara det bästa i både Pugh´s matris och QFD valdes gemensamt ut och fortsattes med. Det gjordes en enkel prototyp av det framtagna konceptet vilket bevisade en mycket bra funktionsduglighet. Med detta noterat och testat gjordes CAD-modeller som utgick ifrån prototypens dimensioner. Den slutgiltiga konstruktionen består av 6 (gånger två) komponenter, en huvudkomponent (spiralfäste), en kabelplatta, två plastkåpor och två skruvar. Dessa bearbetas på olika sätt och monteras samman för att vara redo att användas när kunden plockar dessa ur förpackningen. I jämförelse med den nuvarande produkten QuickPower håller sig resultatet på en nivå som matchar QP. En nackdel är att den inte fäster lika hårt som QP men resultatets enkla användning och resursbesparing höjer produkten.

    A framework supporting the collaboration between the logistics- and the product development process2007Licentiate thesis, comprehensive summary (Other scientific)
    Abstract [en]

    In the competitive environment of today’s global markets, the demands of customers are increasing. They expect to get the best product at the lowest price with immediate availability. Logistics, including transportation, inventory maintenance, order processing, purchasing, warehousing, materials handling, packaging, customer service standards, and product scheduling must continuously be developed to meet the challenges of the market. The globalization, with longer distances to customers and suppliers, and the progressing trend of outsourcing are examples of why the importance of logistics has increased over the last few years.

    A considerable part of the final product cost is frozen during the early product development phases. In the early phases of the product development process, the cost of making design changes is low compared to making changes later in the product development process. The product development decisions made in the early phases of the product development process have considerable impact on future manufacturing and logistics activities as well.

    The objective of this research project is to develop a framework supporting the collaboration between the logistics- and the product development process. To do this, it has been essential to analyze which parameters influence the efficiency of the logistics process and the interface between the logistics- and the product development process. Also, to investigate how the logistics department can be integrated earlier in the product development process has been of interest. This has been done through both a theoretical review and also through a number of case studies.

    The result and conclusion of this project is a framework that gives support for what to focus on, how to collaborate, in which phases collaboration is meaningful, and which persons need to be involved in the different product development phases. Working as the framework suggests will, hopefully, give closer collaboration between the logistics- and the product development process than without this supportive framework. The expectation of the collaboration is an earlier integration of the logistics department in the product development process and through this influence and increase the efficiency of the logistics process.

    Meningsförändrande innovationer inom industrirobotbranschen: En explorativ fallstudie2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In this thesis the subject innovation and the change of meaning is in focus. The purpose of the study is to present a new dimension of innovation as a change of meaning together with the cases we’ve studied. It is discussed throughout the article if theories of perception and association can affect the organization and its ability to create meaning-changing innovations. The industrial robotics is a market in need of, perhaps, if not other markets but of finding new ground that results in the change of meaning. What happens when you stand at the intersection of main areas in the field of innovation? Is it possible that meaningful change can be found here, amongst radical innovation and industrial robotic arms and it’s technology? Our methods were interviews and prior research complementing the cases we’ve presented. We want to show how meaning can change various dimensions. Together with a perceptual theory and an innovation theory we’ve found out that meaning and innovation can go hand in hand.

    CLASSIFYING BASIL AFTER THEIR DIFFERENT GROWTH STAGES USING MACHINE LEARNING2023Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis covers the topic of applying machine learning within the agriculture industry. Thegoal of this project was to set out with the intent of using computers in trying to classify plantsafter their different growth stages with the hope of making it easier for the regular person to growthe their own food. The project set out with trying 3 different machine learning algorithms to getand perspective on how they performed for this specific problem, but also to get an overview onhow the algorithms performed compared to each other. The result and conclusion showed that thealgorithms are currently unfeasible to use, mostly because of the lack of data. Though the resultstill were promising as it proved the concept and that there is potential for further developments onthe work, like the tinkering on the algorithms but mostly of gathering data.

    A different Africa: Spatial information design for a safer refugee settlement2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of this thesis was to explore the spatiality’s affect on refugee’s sense of safety in the Osire refugee settlement in Namibia. The gathered empirics together with previous research and theories should lead to a design for a spatial information system. The system should contribute to peoples’ understanding of their environments’ whole structure as well as showing the way to the health centre and the police station, thus increasing their sense of psychological and physical safety. A wish was also to breathe life into the point of intersection of spatial information design and human science.

    The methods used to enable this were first and foremost a field study in the settlement to experience and acquire first-hand information. In addition observation, introspection and several interviews were conducted.

    As a result I established safety to be an issue that could be solved with spatial design. Refugees expressed that not knowing your environment or finding your way leaves you scared, uncomfortable and confused. With the use of a spatial information system safety can literally be created, as demonstrated in the design proposal. The conclusion is that much could be done to spatially solve complex issues as long as it’s addressed from that perspective.

    Service Level Agreements for Safe and Configurable Production Environments2018In: 2018 IEEE 23RD INTERNATIONAL CONFERENCE ON EMERGING TECHNOLOGIES AND FACTORY AUTOMATION (ETFA), IEEE , 2018, p. 1252-1255Conference paper (Refereed)
    Abstract [en]

    This paper focuses on Service Level Agreements (SLAs) for industrial applications that aim to port some of the control functionalities to the cloud. In such applications, industrial requirements should be reflected in SLAs. In this paper, we present an approach to integrate safety-related aspects of an industrial application to SLAs. We also present the approach in a use case. This is an initial attempt to enrich SLAs for industrial settings to consider safety aspects, which has not been investigated thoroughly before.

    Förbättra leveranssäkerhet mot kund: En utredning för att göra tillverkningsprocessen enklare, rakare och stabilare2012Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Det är vanligt att Svenska företag har leveranssäkerhetskrav på sina underleverantörer. Det är normalt att företag får problem att leverera varorna i tid till sina kunder ibland, vilket kan medföra stor ekonomisk förlust för företaget. Denna rapport är resultatet av ett examensarbete vid Mälardalens Högskola som utförts på uppdrag av International Aluminium Casting AB i Eskilstuna.Syftet med denna rapport är att se över IAC:s fabrik i Eskilstuna ute på Vilsta, för att kartlägga deras tillverkningsprocess och identifiera problemområden i tillverkningen som kan ha direkta effekter på leveranssäkerheten.För att uppnå syftet med arbetet utfördes först en litteraturstudie inom området effektiv produktion, följt av en empirisk studie som utfördes i fabriken på företaget. Detta ger arbetet en hög betryggande anknytning om hur verkligheten ser ut och ger innehållet en bekräftelse emot teorin inom området. En noggrann nulägesbeskrivning utfördes för att få en konkret bild över hur tillverkningsprocessen gick till och för att kunna se vart i processen det finns problem, vilket skulle kunna påverka företagets förmåga att leverera sina varor i tid till kunden. Arbetet resulterar till sist i tre koncept som är förslag på hur företaget skulle kunna öka sin leveranssäkerhet och få en effektivare tillverkningsprocess.En problemidentifiering genomfördes för att se över vart företaget skulle kunna tänkas rikta sina framtida utvecklingsmöjligheter för effektivisera sin tillverkning för att få en starkare leveranssäkerhet. Problemidentifieringen utfördes i flera steg, där företaget ensamma först fick identifiera sin syn på vilka problem dem hade, följt av författarnas uppfattningar baserade på intervjuer och empiriska studier. Till sist intervjuades externa konsulter, varav en fick göra studiebesök på företaget för att få en professionell validering av företaget och stötta upp föregående uttalande. Detta resulterade i många uppfattningar och synvinklar på saker som företaget kan utveckla och växa av.Rapporten avslutas med en diskussion om resultatet och vilka studier som inte hanns med och förslag på områden av framtida utveckling av detta arbete.

    A secure user authentication scheme for critical mobile applications2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Smartphones have facilitated tasks in private and work life for its users. In business,

    employees often should manage sensitive data that unauthorised people cannot access,

    so some user authentication is needed to perform. Besides the normal user

    authentication, some employers give the right to access to the sensitive data only if the

    employees stay in specific locations. That makes sense for those businesses that have

    various construction sites and offices that are not necessarily located in the same

    geographical region. In those companies, the employees must be able to perform their

    tasks from different locations regardless of the available network infrastructure.

    To protect the data from intruders, this research presents a secure location-based user

    authentication scheme for mobile application that works offline. This research considers

    to enable access to the sensitive data using off-the-shelf mobile devices without adding

    any extra hardware and with no additional information from a fixed infrastructure. This

    Thesis firstly describes the architecture and attributes of the proposed solution. Then,

    the techniques used for the design and functionality of the solution are presented. The

    results of this study reveal that the proposed solution is more suitable for the

    applications that is used in outdoor locations. Finally, to alleviate the shortcoming of the

    presented technique for indoor locations, a new method has been discussed and tested.

    This report is a final Thesis in collaboration with SAAB. The purpose of this research is

    to examine the best way to protect sensitive data managed by the employees using their

    smartphones in different workplaces.

    The aim of this paper is to examine the future of networking. Relations to other people are fundamental to building a network and previous research shows the importance of collaboration. An innovative perspective has characterised this study, where innovation means the process where ideas are translated into commercially viable products, processes and services. Through benchmarking including interviews, trend spotting, theory analysis and a workshop, eight elements were identified to be important in the future of networking. These elements are targeted advertising, true open innovation, strong ties, specific attraction, diversity, meetings, environment and gamification, which were the main focus of an idea generation session and a creative workshop. The discussion involves a paradox found between an increased demand of physical meetings and the fact that some participants are experiencing an overflow of meetings. The last part of the discussion concludes thoughts about the innovation process.

    Nytt logistikkoncept för inflöde och lager på Volvo CE, Eskilstuna2012Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Lean Production har blivit det produktionskoncept som många av dagens företag har som modell när de utformar sina produktionssystem. De första stegen mot ett flödesinriktat ”lean” produktionssystem tas ofta genom att transformera produktionen. Detta i sin tur ställer ökade krav på materialleveranser Just-In-Time, materialpresentation och låga lager. För den interna logistiken innebär inte sällan dessa krav betydande merarbete i form av t.ex. omplock av material från större till mindre emballge och kittning av materialsatser. Ska företagen kunna dra full nytta av sitt flödesinriktade produktionssystem måste det även omfatta försöjningskedjan och den interna logistiken. Det är idag en utmaning för den interna logistiken att anpassa sig till de variationer och förändringar som finns i den produktion som den är satt att försörja med material.

    Volvo CE OpESK står inför utmaningen att hantera kraftigt ökande volymer under åren fram till 2015. Dagens internlogistiska upplägg uppvisar begränsningar med avseende på bland annat inflöde och förråd. Dessutom saknas en långsiktig plan för internlogistiken. Detta examensarbete syftar till ta fram ett nytt internlogistiskt upplägg för komponentfabriken i Eskilstuna. Målet är att utifrån det befintliga internlogistiska upplägget, det framtida produktionsupplägget och andra företags logistiklösningar utveckla minst två logistikkoncept för inflöde och förråd som täcker de krav som ställs.

    I examensarbetet har Volvo CE OpESK:s befintliga logistikkoncept, alternativa logistiklösningar och de förväntade volymförändringarnas påverkan på inflöde och lager kartlagts, utvärderats och analyserats. Resultatet av arbetet har gett en beskrivning av hur den interna logistiken kommer att påverkas och vilka möjliga lösningar som finns för att möta detta. Med detta som utgångspunkt har ett antal koncept arbetats fram varav två har rekommenderats.

    Det första konceptet omfattar en logistiklösning för inflödet i godsmottagningen och logistikcentret. Rekommendationen från författaren är att Volvo CE OpESK i första hand ändrar arbetssätt vid inflödet för att öka kapaciteten, samt anpassar förråden i logistikcentret både till layout och storlek för att passa volym och materialmix år 2015. Nästa steg innebär att komplettera nuvarande bansystem med ytterligare banor för att öka flexibiliteten, minska sårbarheten och förbättra ergonomin för logistikpersonalen. Målet är att reducera mängden onödigt arbete även i godsmottagningen.

    Det andra konceptet omfattar höglagret. Här rekommenderas att stapelkranar och bansystemet för material in och ut ut höglagret renoveras för att reducera antal stopp och störningar. Vidare bör en strategi fastställs för höglagrets fortsatta användning. I ett andra steg rekommenderas att banor ersätter den befintliga transfervagnen vid in- och utleveranser av material för att minska sårbarheten.

    Under arbetet med konceptstudien har även arbetsprocessen utvärderats. Syftet har varit att ta fram riktlinjer för hur företaget kan arbeta med att utveckla koncept för internlogistik. Slutsatserna från utvärderingen är att använda en utvecklingsmodell, gå igenom grundförutsättningar innan arbetet startar, ta reda på fakta, inget system är för enkelt för att behandlas, ifrågasätt varför nya lösningar ska användas och bestäm principer och metoder innan tekniken väljs.

    Energy assessment of Paper Machines2012In: Energy Procedia, ISSN 1876-6102, Vol. 14, p. 955-963Article in journal (Refereed)
    Abstract [en]

    There is a large value in making Pulp and Paper mills more energy efficient. ABB has developed an energy assessment service where opportunities to save energy in the paper machine are identified. The energy assessment is done by quantifying energy flows, benchmarking energy users, data mining and steam sensitivity analysis and by experiments and additional measurements at the paper machine. Energy quantification helped in identifying main energy consumer, benchmarking was useful to assess the gap between operating performance and best performance whereas data mining and steam sensitivity analysis helped in studying the impact of key operating variables on performance of paper machines. After the assessment an action plan was presented to the mill for energy efficiency improvement together with a return on investment.

    F-3-lärares attityder till teknikämnet: En kvalitativ studie om vilka attityder F-3-lärare har till teknikämnet2023Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med den här studien är att undersöka vilka attityder F-3-lärare har till teknikämnet, vad attityderna kan grunda sig i och hur F-3-lärares attityder kan påverka teknikundervisningen. Det undersöks eftersom lärares attityder till ett ämne kan påverka elevernas intresse och kunskapsutveckling samt hur teknikundervisningen utformas. Studien har genomförts med hjälp av semistrukturerade intervjuer och systematiskt analyserats. Resultatet visar att lärare har både positiva och negativa attityder till teknikämnet som grundar sig i faktorer i omgivningen och lärares självförmåga. Oavsett attityd vill lärare lära sig mer om teknik. Teknikämnet får olika stort utrymme i undervisningen beroende på vilken attityd lärare har. Slutsatsen för den här studien är att lärares attityder till teknikämnet varierar, attityderna är både positiva och negativa. Attityderna grundar sig i lärares självförmåga och faktorer i omgivningen. Positiva attityder leder till att teknikundervisningen genomförs oavsett om den upplevs utmanande eller inte. Negativa attityder leder till att teknikundervisningen väljs bort om uppgifterna upplevs för utmanande att genomföra eller inte uppfattas som lika viktiga som andra ämnen.

    Evaluation of a Modular Thermally Driven Heat Pump for Solar Heating and Cooling Applications2015Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    Exploiting solar energy technology for both heating and cooling purposes has the potential of meeting an appreciable portion of the energy demand in buildings throughout the year. By developing an integrated, multi-purpose solar energy system, that can operate all twelve months of the year, a high utilisation factor can be achieved which translates to more economical systems. However, there are still some techno-economic barriers to the general commercialisation and market penetration of such technologies. These are associated with high system and installation costs, significant system complexity, and lack of knowledge of system implementation and expected performance. A sorption heat pump module that can be integrated directly into a solar thermal collector has thus been developed in order to tackle the aforementioned market barriers. This has been designed to aid in the development of cost-effective pre-engineered solar energy system kits that can provide both heating and cooling.

    This thesis summarises the characterisation studies of the operation of individual sorption modules, sorption module integrated solar collectors and a full solar heating and cooling system employing sorption module integrated collectors. Key performance indicators for the individual sorption modules showed cooling delivery for 6 hours at an average power of 40 W and a temperature lift of 21°C. Upon integration of the sorption modules into a solar collector, measured solar radiation energy to cooling energy conversion efficiencies (solar cooling COP) were between 0.10 and 0.25 with average cooling powers between 90 and 200 W/m2 collector aperture area. Further investigations of the sorption module integrated collectors implementation in a full solar heating and cooling system yielded electrical cooling COP ranging from 1.7 to 12.6 with an average of 10.6 for the test period.

    Additionally, simulations were performed to determine system energy and cost saving potential for various system sizes over a full year of operation for a 140 m2 single-family dwelling located in Madrid, Spain. Simulations yielded an annual solar fraction of 42% and potential cost savings of €386 per annum for a solar heating and cooling installation employing 20m2 of sorption integrated collectors.

    Demonstration of Solar Heating andCooling System using Sorption Integrated Solar Thermal Collectors2014In: EuroSun 2014 Conference Proceedings, 2014, p. 523-532Conference paper (Refereed)
    Abstract [en]

    Producing cost-competitive small and medium-sized solar cooling systems is currently a significant challenge. Due to system complexity, extensive engineering, design and equipment costs; the installation costs of solar thermal cooling systems are prohibitively high. In efforts to overcome these limitations, a novel sorption heat pump module has been developed and directly integrated into a solar thermal collector. The module comprises a fully encapsulated sorption tube containing hygroscopic salt sorbent and water as a refrigerant, sealed under vacuum with no moving parts. A 5.6m2 aperture area outdoor laboratory-scale system of sorption module integrated solar collectors was installed in Stockholm, Sweden and evaluated under constant re-cooling and chilled fluid return temperatures in order to assess collector performance. Measured average solar cooling COP was 0.19 with average cooling powers between 120 and 200 Wm-2 collector aperture area. It was observed that average collector cooling power is constant at daily insolation levels above 3.6 kWhm-2 with the cooling energy produced being proportional to solar insolation. For full evaluation of an integrated sorption collector solar heating and cooling system, under the umbrella of a European Union project for technological innovation, a 180m2 large-scale demonstration system has been installed in Karlstad, Sweden. Results from the installation commissioned in summer 2014 with non-optimised control strategies showed average electrical COP of 10.6 and average cooling powers between 140 and 250 Wm-2 collector aperture area. Optimisation of control strategies, heat transfer fluid flows through the collectors and electrical COP will be carried out in autumn

    Abstract [en]

    RESEARCH QUESTIONS: (1) How are employee’s supported to conduct innovative work? (2) How does the conditions for employee involvement differ between the municipalities?

    PURPOSE: The aim of this study is to examine change- and improvement processes from a employee driven/high-involvement perspective, as well as the conditions for innovation in municipal home care services within a larger and smaller municipality.

    METHOD: Data in this study has been collected with the aid of qualitative interviews, as well as a quantitative survey. The interviews were conducted on four participants with some sort of leader position to obtain knowledge about how employee involvement is applied in the current situation. The survey was carried out on employees in each municipality’s home care service, with the intention to look into their general point of view and attitude regarding innovation and employee involvement.

    CONCLUSION: Although at present there’s no full-fledged reality within the examined organizations, there is still support to be found in both earlier research and the results obtained in this study for the development potential of home care services towards employee driven innovation. Not enough organizational slack, as well as lack of opportunity for decision-making and initiative among employee’s in daily work is seen as potentially aggravating factors in the adoption of employee driven innovation.

    Från internkund till hockeyspelare: En innovativ studie om samarbete på ICA Logistik2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This paper aims to come up with an innovative definition of the internal customer construct as well as an implementation strategy for a logistics unit of the Swedish grocery wholesaler ICA. We have reached our conclusions through creative study visits, interactive interviews, an innovative workshop, and by reading up on research. We have focused on lean management and theories about organizational culture, trust and communication and found connections to efficiency and effectiveness in all fields. During our interviews we discovered that ICA was facing some challenges concerning trust, communication and an individualistic mindset among the workers. We therefore tried to incorporate these problems into our concept Team Logistics in which the internal customers and suppliers are referred to as Centers and Backs, all in line with our ice hockey approach. As for the implementation strategy we recommend ICA to use positive incentives to build trust and boost the dialogue between in-chain departments. The goal is for the concept to increase efficiency and effectiveness.

    Optimising the Planning- and Scheduling in a Complex Production: Discrete-Event Simulation in a pharmaceutical context2022Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The aim of this study is to investigate the optimisation of production planning- and scheduling in a pharmaceutical facility using DES.Research questions: “How can DES be used to achieve flexibility and efficiency in a pharmaceutical facility?” and “How can DES be used to increase efficiency of the resource allocation in a pharmaceutical facility?”Methodology: This study has been compared to a deductive- and a quantitative research approach where a process simulation has been modelled. The theoretical framework was based on books and scientific publications. Empirical data was collected through unstructured observations at the production site, frequent meetings together with the company and through the company’s database Discoverant. Based on the results from the simulation model conclusions could be drawn.Conclusion: The study concluded that there are bottlenecks at the beginning of the processes in all three production flows for Medicine A, Medicine B and Medicine C. If these are raised it would generate greater flexibility and efficiency in the production. There were also indications of a new allocation of resources that would raise efficiency in the production, thus making it possible to increase the output from the production.

    Addressing dual embeddedness: The roles of absorptive capacity and appropriabilitymechanisms in subsidiary performance2019In: Industrial Marketing Management, ISSN 0019-8501, E-ISSN 1873-2062, Vol. 78, p. 239-249Article in journal (Refereed)
    Abstract [en]

    This study examines how subsidiaries can manage dual embeddedness with both local partners and a multinational enterprise. Specifically, we examine the role of absorptive capacity and appropriability mechanisms on subsidiary performance. We analyse how absorptive capacity and appropriability enable subsidiaries to successfully address knowledge challenges related to internal and external networks. We conducted an empirical analysis on a sample of 165 subsidiaries. Our results suggest that absorptive capacity has a direct, positive effect on subsidiary performance, which is greater in emerging countries. The study also found an indirect effect of absorptive capacity on subsidiary performance, which is mediated through appropriability mechanisms. These findings extend the literature on international networks, dual embeddedness and absorptive capacity.

    Denna studie lyfter behov och känslor från företag och studenter i frågor om samverkan och vikten av nätverk. Det fastställs även i studien att studenter är osäkra och omedvetna kring vad för roller de kan axla efter sin utbildning samt vad de innebär. Studenter på Mälardalens högskola känner att det är för lite samverkan gentemot företag och poängterar att mycket eget initiativ krävs. Företag vet inte hur de ska ta sig in till högskolan och visa upp sig. Sociala medier är ett bra verktyg för att visa upp sitt varumärke men det som kommit fram är att det krävs mer än så. Studenter vill se företag i skolan och få chansen att bygga relationer. Det krävs mer interaktion för att tillfredsställa parterna. Det kan även minska rekryteringsprocesser, kostnader och felrekrytering medan studenter får mer självförtroende och kontroll över sin utbildning och vad hen vill söka sig till.

    Comparative assessment of waste-to-energy potential in European regions2012Conference paper (Refereed)
    Abstract [en]

    This paper presents the results of assessment of the current status of waste-to-energy utilisation in five selected regions, which was conducted within the REMOWE (Regional Mobilizing of Sustainable Waste-to-Energy Production) project. The REMOWE project is part of the Baltic Sea Region Programme 2007-2013 and has been partly-financed by the European Union. The objective of this paper is the evaluation of the current practice with focus on the best practices that can be transferred to other regions. The selected regions are Estonia; Lower Silesia (Poland), Western Lithuania and North Savo Region (Finland) and the County of Västmanland (Sweden). The current situations in the project regions are presented with regard to the waste generation and treatment and the potential to use waste as RES. The waste types which were identified as relevant for energy recovery include municipal waste, sewage sludge, industrial waste (two streams: one suitable for biogas generation and the other one as alternative fuel for combustion) as well as animal manure. The greatest energy potential show residual municipal waste (68% of the total potential) and animal manure (24%). Energy recovery from these wastes should be a priority in waste management systems of individual regions. Current energy recovery from waste is very low in the considered regions, except for the County of Västmanland, where app. 68% of the waste to energy potential is utilised.

    Keywords: waste, renewable energies, sustainability, residues.

    Evaluating Lean Manufacturing Proposals through Discrete Event Simulation – A Case Study at Alfa Laval2013Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In their strive for success in competitive markets companies often turn to Lean philosophy. However, for many companies Lean benefits are hard to substantialize especially when their ventures have met success through traditional manufacturing approaches. Traditional Lean tools analyze current situations or help Lean implementation. Therefore productions facilities require tools that enhance the evaluation of Lean proposals in such a way that decisions are supported by quantitative data and not only on a gut feeling.

    This thesis proposes how Discrete Event Simulation may be used as an evaluation tool in production process improvement to decide which proposal best suits Lean requirements. Theoretical and empirical studies were carried out. Literature review helped define the problem. A case study was performed at Alfa Laval to investigate through a holistic approach how and why did this tool provide a solution to the research questions. Case study analysis was substantiated with Discrete Event Simulation models for the evaluation of current and future state Lean proposals.

    Results of this study show that Discrete Event Simulation was not designed and does not function as a Lean specific tool. The use of Discrete Event Simulation in Lean assessment applications requires the organization to understand the principles of Lean and its desired effects. However, the use of traditional static Lean tools such as Value Stream Mapping and dynamic Discrete Event Simulation complement each other in a variety of ways. Discrete Event Simulation provides a unique condition to account for process variability and randomness. Both measurement of and reduction in variability through simulation provide insight to Lean implementation strategies.

    Abstract [en]

    During this study the authors had an assignment from a client which was creating a new Agile project methodology for the client, to promote their work on the project they undertake annually, named Jobb Shop. The project had during the last execution not been implemented by means of a specific project methodology. During this process the authors of this study created a specific agile methodology for the client that they can use in future years in the implementation of Jobb Shop. Alongside this, the authors also did a meta-analysis of the new method in which they studied how the new agile method, theoretically, can promote creativity and innovation. The results of the study showed that the theoretical basis for the above question was good, and they concluded that agile methods, theoretically, may well promote creativity and innovation.

    Abstract [en]

    This work is about deicing of runways at an airport. The traditional method of deicing the runways is to plow, brush, sweep and spray the surface with anti-icing chemicals. The entire process is very costly for an airport and requires large resources of both machines, personnel and chemicals.

    In this thesis it is analyzed if the cost of deicing could be reduced if a new deicing method is used. The new method is to put heat pipes under the asphalt to melt the snow. The power of such a system needs to be quite high in order to have the capacity to keep the surface free from snow and ice. To reduce the energy cost of power consumption the cost of different energy sources is compared with each other. It has been of great importance because the gain that can be achieved with the installation of the system depends on the annual cost of energy consumption.

    The installation of a heating system for handling the deicing at an airport has shown good potential for the contribution of an economic gain. There is a wide variety of energy sources available to use for energy supply that can reduce the annual cost for deicing, compared with traditional deicing methods. However it is of much importance to use the energy source with the lowest operating cost for the system, as this will allow it to earn back the investment cost for the system as soon as possible. The ability to regulate the power of the system when necessary keeps the energy consumption as low as possible and thus reduces operating costs.

    The work restricts the installation of the system to new buildings of airports and uses energy calculations that requires inputs depending on weather and wind. Arlanda is used as a reference airport. This to collect the required data and to put the results in relation to Arlanda. It turns out that an airport in the Stockholm area, with the same dimensions and costs of traditional deicing as Arlanda, can make an annual financial gain of 32, 45 million SEK. This means that a heating system earns back its installation cost within a period of 2.5 years. The prerequisite is that the system is limited to the areas where it is most beneficial. That will keep down the high installation costs. The conclusion is that a heating system in central Sweden and further north is economically advantageous, while it is not certain how favorable it is considered at the bottom of southern Sweden. This is due to the high installation costs and that the deicing costs for traditional deicing are relatively low in that area. This may mean that the system is not allowed to earn back its investment cost for a sufficiently short period of time. That may cause the system to be considered an unnecessary investment. However, the annual cost of deicing can be reduced independent of where in Sweden the airport is located.

    Lean i offentlig förvaltning: En studie av leanimplementeringen inom Trafikverket2014Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Problem, Lean is a working method that has become more common in the public sector as it is expected to streamline everyday operations. A demand that more organizations need to consider. Within academic circles the efficiency of Lean is discussed, but also what is actually included in the concept of lean. The Swedish Transport Administration has implement lean as working method within a specific part of the organization, consisting of Traffic Engineers from six different regions. The aim is to streamline four different case management teams in their work. A previous quantitative survey has shown that the experience of lean and lean implementation varies in the different regions. This study focuses on finding out why.

    Purpose, The purpose of the study is to evaluate the Swedish Transport Administrations lean implementation and seek answers for why the regions have embraced the approach to different degrees, and why attitudes to lean differ between the regions.

    Method, The study's objective was to examine the underlying causes of why the attitudes towards lean differ among the different regions. Therefore, the study was based on a qualitative approach with semi-structured interviews. These interviews were conducted in groups with traffic engineers to get a more region-specific overview of the problem. Interviews were also also conducted with the lean implementation managers in each region. The basis for the conclusions presented in this study are these interviews and an interdisciplinary review of previous research in the areas of: Innovation, Lean, Theory of Change and Organizational Culture.

    Conclusion, Organizational Change is a subject that is often treated mechanically, but with an organizational change, there must be an understanding of the complex systems that function within the organization. A change will engage and change the conditions for more employees than those directly involved, which affects the entire organization.Lean as a work method is more than a number of tools. There is an overarching philosophy that the Transport Administration needs to understand and make their own if they are to succeed in their lean work. Attitudes about lean depends on several factors. The regions experiencing that they previously had problems and that with lean have experienced an improvement is more in favor of lean as a working method. They also feel they have more influence on their work and that they are able to point out what they think needs to change. These regions give expression that communication in the implementation phase has been clear and correct. The regions who has taken a negative view to lean expresses that they have not had any problems with its previous approach. They also feel that lean mean a locking of the work where they used to be able to come up with their own initiatives and that they must now adapt to working methods that are not designed for the their specific needs. Communication has been experienced vague or nonexistent. In some cases, the attitudes towards lean have been directly affected by the spread of rumors that have arisen in the absence of clear information.

    Abstract [en]

    The purpose of this study is to compare cooling from a refrigeration machine and a borehole system. These technologies are chosen because they are observed as each other’s opposites. A refrigeration machine is associated with a requirement of large amounts of electric energy, while the borehole system is often seen as free cooling.

    The study is performed on a fictional building located in Västerås. The building has an area of 2 000 m² and a cooling requirement of 50 W/m². In the scenario studied the building is already equipped with a refrigeration machine, the goal is to examine if it can be motivated to remove this machine and replace it with a borehole system. The chosen environmental impact categories are embodied energy and carbon dioxide equivalents. In order to evaluate the embodied energy, EROI (Energy return on investment) is used to calculate the energy saved by removing the refrigeration machine.

    For the refrigeration machine most of the energy used is during the operation phase, this is because of the compressor which is used to produce cooling energy. In the borehole system 40 % of the energy used is during the operation phase and 60 % during the manufacturing phase. The drilling used 8.1 m3 diesel fuel, which dominated both the embodied energy and the carbon dioxide emissions of the borehole system.

    Results show that after only 4.5 years after installation the borehole system has less total embodied energy. EROI was then calculated as saved energy divided by invested energy and the result was an EROI of 7.4. The carbon dioxide emissions from both systems are heavily dependent on the CO2-emissions from electricity generation. Though, if a refrigeration machine were used during the buildings entire lifetime the leakage of refrigerant would be big enough to counteract this dependence.

    Managing complex projects in the infrastructure sector: A structural equation model for flexibility-focused project management2017In: International Journal of Project Management, ISSN 0263-7863, E-ISSN 1873-4634, Vol. 35, no 8, p. 1512-1523Article in journal (Refereed)
    Abstract [en]

    Complex construction projects in the infrastructure sector are often beset with delays, which cause benefit shortfalls and increased costs. Prior project management literature and practice have mostly adopted a traditional control-focused approach, but recent research suggests that complex projects need more flexible practices to manage inevitable project change. Thus, the objectives of this study were to develop and empirically test a model for flexibility-focused project management practices to improve time performance in complex projects in the infrastructure sector. Based on empirical data from 138 construction projects procured and managed by the Swedish Transport Administration, the structural equation model shows that complexity and collaboration drive explorative learning, which improves adaptation and thereby improves time performance. Hence, the empirical test verifies that flexibility-focused project management practices based on collaboration, explorative learning, and adaptation enhance time performance in complex projects in the infrastructure sector.

    Buyer-supplier integration in project-based industries2013In: Journal of business & industrial marketing, ISSN 0885-8624, E-ISSN 2052-1189, Vol. 28, no 1, p. 29-40Article in journal (Refereed)
    Abstract [en]

    Purpose - The purpose of the study is to propose and test a buyer-supplier integration model, based on clients’ collaborative purchasing practices, in a project-based industry.Design/methodology/approach - A two-stage survey study of client-contractor relationships in the Swedish construction industry was conducted. The survey rounds in 2006 and 2009 obtained 87 and 106 responses respectively. The proposed model was empirically tested using structural equation modeling techniques. Findings - The empirical results support our proposed model: incentive-based payment and partner selection based on multiple criteria enhance buyer-supplier integration, in terms of joint action. Furthermore, incentive-based payment increases the use of partner selection based on multiple criteria.Research limitations/implications - A useful theoretical contribution is that incentive-based payment is an important type of incentive structure that enhances buyer-supplier integration in project contexts.Practical implications - We also found that the occurrence of joint action has been increasing from 2006 to 2009. Especially, incentive-based payment plays a more important role for establishing joint action in 2009 than in 2006. The recent economic downturn and a recently completed training program targeting the survey population may explain some of the unexpected findings.Originality/value - The paper addresses an identified gap in the relationship marketing literature, that is, the lack of quantitative studies of relationship marketing aspects in project-based industries.

    Modelling procurement effects on cooperation2007In: Construction Management and Economics, ISSN 0144-6193, E-ISSN 1466-433X, Vol. 25, no 8, p. 893-901Article in journal (Refereed)
    Abstract [en]

    Cooperative arrangements, such as partnering, have received increased interest in recent years. Several studies show however that cooperative relationships are not easily achieved in construction. Implementation of cooperative relationships requires changes in several elements of the traditional procurement procedures. The purpose of this paper is therefore to propose and test a sequential model regarding clients' cooperative procurement procedures. We especially ask: what elements in clients' procurement procedures facilitate the establishment of cooperation and trust in their relationships with contractors? The model was tested through structural equation modelling. The empirical data required for the test were collected through a survey responded to by 87 Swedish professional construction clients. The empirical results show that cooperative procurement procedures are triggered by clients' wish to involve contractors early in specification, which has a simultaneous effect on procedures regarding bid invitation and compensation. Furthermore, these simultaneous effects breed a certain kind of partner selection based on task-related attributes, which also has a direct positive effect on trust and above all on cooperation in client-contractor relationships. Besides these implications from the model, the improvement of measurements for future modelling is discussed.

    Abstract

    Segerström Automotive manufacture sheet metal components to customers like Scania, Stiga and Volvo. The company is expanding, but the competitiveness and the quality requirements on the market are high. The company is quality certified. As part of the work with quality and improvements Segerström Automotive Production System, SAPS, was restarted during the spring 2007. One of the goals for the organization is to decrease the number of external reclamations. To be able to reach the goal a study of what have caused the stagnation of the number of reclamations towards the company was considered as necessary. Thus the thesis has been focused on analyzing the quality work within the organization, with its core in the reclamation handling. Areas for improvements have also been discussed. Both qualitative and quantitative methods have been used; for example interviews, data gathering and observations. The main theories used come from lean production and Total Quality Management.

    A deviation occurs when a product does not meet the customer requirements. Reclamations communicate a deviation. It was found that the external reclamations towards Segerström often were symptoms of internal deviations. Because there is no system for internal reclamations the deviations that are found internally rarely lead to any actions. There is often a lack of time and resources dedicated to analyze the root cause and to take necessary actions to eliminate them; the failure modes are repeated. Parts of the lack of resources could be solved by an organizational change, where clear roles and responsibilities within the fields of quality and improvements were specified.

    The company already has a number of different documents and methods to work with quality and improvements, but those are not implemented and used in a necessary extent. The challenge for Segerström is to choose which documents and methods to use and how to implement them. Routines should be created to link the different parts, methods and documents. To standardize and document more of the repetitive activities, identify internal customers, analyze where in the chain details should be measured, establish channels for communication, have quality responsible persons at the work stations in the production, educate the personnel in quality, create a system for recognition and rewards, document costs of quality and analyze how to gather and spread information about quality to the personnel are areas as the company should look closer into.

    It is important that the leaders of the company give the resources necessary, builds a structure to work from and follow up the work. To succeed quality has to be prioritized within the whole organization.

    ABSTRACT

    This thesis work consists of a case study, where August Lund AB assigned the further development of an ergonomically designed plastic serving pitcher. The purpose of the assignment was to further develop the serving pitcher, to adapt it for hot beverages and the manufacturing method injection molding, and to serve as a basis for decision making regarding how further investments in the previously produced ergonomic design solution was to be made. To achieve this, the following thesis question was formulated: Which are the leading factors that dictates the product development of plastic products that will be injection molded?

    To be able to answer the thesis question and complete the development of the pitcher a literature study about plastic design was conducted, that formed the foundation of the theoretical framework. Secondary data was collected using academic literature consisting of books and scientific papers. A product development process was formed for the case study, that was a derivative of the generic product development processes presented in the literature used. To complete the theoretical framework for the case study primary data was collected by conducting laboratory testing, simulations, tests and interviews.

    The main part of the work conducted in the case study consisted of finding a satisfactory insulation solution, that would prevent the user of the pitcher from getting burned by the heat from the hot beverage. This resulted in that the product development never reached beyond the conceptual phase. Two different methods of insulation were explored. The first method consisted of a thermoplastic elastomer overmolding that was located at the gripping area. It was concluded from the conducted laboratory testing and the simulations that the thickness of the grip had to be at least 10 mm. The thickness necessary was regarded as to thick because of the associated manufacturing costs and the proposed method was rejected. The second method explored was a pitcher containing an inner pitcher that formed an insulating air gap. The simulation result indicated that a 3.5 mm air gap was necessary to obtain adequate insulation. An insulation method using an air gap in combination with the ergonomic design solution brings several unsolved problems, that need further investigation to be solved if the combination is to be used.

    The employer had the request of investigating if a thermos effect could be achieved. The result showed that an air gap would insulate the pitcher so that a 10°C higher beverage temperature would be achieved during the 45 minutes than if an uninsulated pitcher was to be used. To attain a better thermos effect, the air gap could be filled with a foam to reduce the convective heat transfer in the air gap. Reaction Injection Molding could potentially be used to produce the insulating foam.

    It was concluded based upon the case study and the theoretical framework that the leading factors that dictates the product development of plastic products that will be injection molded was the structural constraints and the design guidelines of plastic design. Also, the cost of manufacturing in relation to the product performance, the products potential selling price and the production volume. In another word, to be able to asses which changes of the design that leads to increased manufacturing cost and if the increase is justifiable in relation to the obtained product performance. DFM turned out to be essential and have a central role in the product development of plastic products that will be injection molded.
