    Abstract [en]

    Today, the drive in many organizations is to focus on reducing production costs while increasing customer satisfaction. One key to succeed with these goals is to develop and improve both quality and maintenance in production as well as quality and maintenance in early phases of the development processes. The purpose of this paper is to discuss how and motivate why research within quality and maintenance development may interact, in order to help companies meet customer demand while at the same time increase productivity. The paper is based on ideas and research perspectives of the newly formed competence group on ‘Quality- and Maintenance Development’ at the School of Innovation, Design and Engineering at the Malardalen University, Sweden. This paper elaborates on the concepts of Quality and Maintenance, its important integration, and provides some examples of ongoing research projects within the competence group.

    On the Need for Research on Holistic Maintenance2009Inngår i: CONDITION MONITORING AND DIAGNOSTIC ENGINEERING MANAGEMENT: Proceedings of the 22th international congress on Condition Monitoring and Diagnostic Engineering Manangement, Eibar: Fundacion Tekniker , 2009, s. 165-172Konferansepaper (Fagfellevurdert)
    Abstract [en]

     

    Traditionally, research within maintenance has been viewed from an operations research and maintenance optimization perspective, based on the mathematical theory of reliability. Utilizing an analytical approach with mostly quantitative methods, renewal theory, reliability tests, failure rate estimates, fatigue life in materials, and so on, have been researched and analyzed [1, 2]. However, Dekker [3], for instance, points out that there are, in many areas, complaints about the gap between theory and practice. Thus, in order to help companies realizing a more efficient maintenance execution and benefit from the performed research, other research perspectives might be important as well.

    This paper argues for the need of having an applied systems approach when performing research on maintenance design and development. The purpose of having such a research approach is to bridge some of the gap between theory and practice when it comes to development of new innovative philosophies/methodologies/techniques and the implementation of these in industrial contexts. The paper is divided in a Section on introduction and a background to the issue, a Section on the need for research on holistic maintenance, and end with a Section of discussion, presenting some ideas on how to perform research on holistic maintenance and an introduction to the research group on 'Maintenance Development' at Mälardalen University, Sweden.

    Handbok för att minska underhållsrelaterade slöserier2016Rapport (Annet vitenskapelig)
    Abstract [en]

    ENLIGT HEMSIDAN ”www.phrases.org.uk”(2016-02-25) myntade författaren Daniel Defoe frasen ’döden och skatter’ år 1726 och fler har sedan följt i hans fotspår. En av de kanske mest kända formuleringarna kom till i ett samtal mellan Benjamin Franklin och Jean-Baptiste Leroy (1789): ”I denna värld kan ingenting sägas vara säkert, utom döden och skatterna.” (fritt översatt från engelska). Vi har även funnit en person som använt det här uttrycket kopplat till underhåll, nämligen Kevin Marshall som diskuterar underhåll av hyreshus: ”...döden, skatter och underhåll.” (”www.flat-living.co.uk”, 2016-02-25). Underhåll i någon av alla dess former är någonting alla människor på jorden upplever nästan dagligen, medvetet eller omedvetet. Det finns egentligen bara ett sätt att tackla detta – med ett leende på läpparna. Man behöver dock inte vara slösaktig. På samma sätt som väldigt få vill betala mer i skatt än vad lagen kräver så vill sällan någon betala mer för underhåll än vad nöden kräver. Det är vad denna handbok handlar om. Den vänder sig till tillverkande företag som önskar minska sina underhållsrelaterade slöserier, och därför har behov av att se över sin verksamhet. Boken vänder sig i första hand till ledningsgrupper för underhåll, underhållschefer och underhållsutvecklare/ingenjörer. Dock, för att citera en av våra samarbetspartners: ”Det är ett slöseri om bara anställda inom underhållsavdelningen läser boken.” För att nå ett hållbart resultat är vi övertygade om att medvetenheten om slöserier och underhållsrelaterade slöserier behöver höjas bland samtliga anställda i en verksamhet. Detta är anledningen till att vi vill att du använder handboken. Vi uppmanar till att du läser exemplen och diskuterar frågorna med medarbetare inom hela underhållsavdelningen, och gärna tvärfunktionellt med produktion och övriga stödfunktioner. Vårt mål är att ge vägledning för hur tillverkande företag kan arbeta med underhållsrelaterade slöserier. Boken klargör vad sådana slöserier är, samt tips och idéer på hur man kan identifiera, klassificera och kvantifiera dem. Handboken presenterar även en arbetsprocess för att minska eller ta bort underhållsrelaterade slöserier så kostnadseffektivt som möjligt. Den innehåller också korta teoriavsnitt med exempel från praktiken och frågor som ledningsgrupper och anställda inom verksamheten kan diskutera. Genom att följa arbetsprocessen kan du och ditt företag få ökad medvetenhet och förståelse för underhållsrelaterade slöserier inom er egen verksamhet. Handboken fokuserar främst på de tidiga stegen i processen eftersom de är mest avgörande för ett lyckat resultat. Underhållsrelaterade slöserier är delvis unika för varje företag. Tyvärr finns inga genvägar eller standarder för att minska eller ta bort dem. Att endast läsa handboken kommer inte att ge något resultat. Den här boken bygger på att du och ditt företag aktivt finner er egen väg för att minska eller ta bort de underhållsrelaterade slöserier ni upptäcker i er verksamhet.

    Machine criticality assessment for productivity improvement Smart maintenance decision support2019Inngår i: International Journal of Productivity and Performance Management, ISSN 1741-0401, E-ISSN 1758-6658, Vol. 68, nr 5, s. 858-878Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose The purpose of this paper is to increase productivity through smart maintenance planning by including productivity as one of the objectives of the maintenance organization. Therefore, the goals of the paper are to investigate existing machine criticality assessment and identify components of the criticality assessment tool to increase productivity. Design/methodology/approach An embedded multiple case study research design was adopted in this paper. Six different cases were chosen from six different production sites operated by three multi-national manufacturing companies. Data collection was carried out in the form of interviews, focus groups and archival records. More than one source of data was collected in each of the cases. The cases included different production layouts such as machining, assembly and foundry, which ensured data variety. Findings The main finding of the paper is a deeper understanding of how manufacturing companies assess machine criticality and plan maintenance activities. The empirical findings showed that there is a lack of trust regarding existing criticality assessment tools. As a result, necessary changes within the maintenance organizations in order to increase productivity were identified. These are technological advancements, i.e. a dynamic and data-driven approach and organizational changes, i.e. approaching with a systems perspective when performing maintenance prioritization. Originality/value Machine criticality assessment studies are rare, especially empirical research. The originality of this paper lies in the empirical research conducted on smart maintenance planning for productivity improvement. In addition, identifying the components for machine criticality assessment is equally important for research and industries to efficient planning of maintenance activities.

    AN INDUSTRIAL PERSPECTIVE ON FLEXIBLE MANUFACTURING: A FRAMEWORK FOR NEEDS AND ENABLERS2013Inngår i: International Conference on Production Research, 2013Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Flexibility of manufacturing systems, as a key factor of survival in the market, is regarded as the ability of handling changes in variants and volume governed by different capabilities depending on system level and manufacturing process. Research on flexibility has been of interest over years, resulting in a vast field of organizational, technical, and process-based enablers. The practical review in terms of needs, enablers and implementations of changeable production systems is however scarce. The objective of this paper is to present an initial review of industrial practice regarding flexibility in manufacturing systems, based on the current frame of reference and empirical study of two manufacturing companies in Sweden which helps industrial companies to identify their flexibility needs and the required enablers to achieve them.

    Strategic maintenance management: Formulating maintenance strategy2013Inngår i: International Congress Condition monitoring and Diagnostic Engineering Management, 2013Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In recent decades, by introducing lean manufacturing the vulnerability to system disturbances has increased and so, the demand for dependable production equipment. The need for having high production equipment availability causes companies to need a more effective and efficient maintenance strategy in order to stay competitive. Despite the increasing demand on reliable production equipment, few manufacturing companies work with strategic maintenance development and a large part of the manufacturing industry lack clear maintenance strategies. It is therefore difficult to develop the maintenance work in accordance with the strategic goals of the manufacturing companies. The main objective of this paper is to define a process for formulating maintenance strategy in order to facilitate further development in a strategic way. The problem has been studied by literature review and through case study at one major manufacturing site in Sweden to investigate the company’s view on strategic maintenance development. Hence, a formulated maintenance strategy has been provided and presented. The company’s overall goals considered and translated to the strategic objective of maintenance. Moreover, balanced score card is used as a tool to make a framework of the maintenance strategy. As a result of this study, the company could easily formulate a maintenance strategy by using a simple process based on the tools that they have already used. In addition to this, the result indicated how maintenance strategy can contribute to the company’s business goals.

    CONDITION BASED MAINTENANCE IN MANUFACTURING INDUSTRIES: INTRODUCING CURRENT INDUSTRIAL PRACTICE AND CHALLENGES2013Inngår i: 22nd International Conference on Production Research, ICPR 2013, 2013Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This paper presents an introductory review of CBM practice applied in manufacturing industry, focusing the technical constituents within condition monitoring. The empirical base for the study is a case study of two major manufacturing sites in Sweden, complemented with a brief benchmark of data from two reference manufacturing sites from France and Brazil. The data from the main studies were collected by interviews and document analysis. The result indicates that there is a wide range within current practice of applying CBM. The implementations are dependent on process type (machining, assembly or heat treatment) and product type. By analysing the empirical data, gaps and challenges for implementing CBM in industry are presented, primarily focusing condition monitoring within manufacturing industry. The paper concludes with a discussion on possible future trends and research areas, needed to increase the industrial use of CBM.

    A Work Process for Formulation of Maintenance StrategiesManuskript (Annet vitenskapelig)
    Abstract [en]

     

    Abstract

    Purpose – The purpose of this study is to develop and validate a work-process for formulation of maintenance strategies within manufacturing industry.

    Design/methodology/approach – Literature studies and an industrial case study are combined to develop the proposed work-process.

    Findings – A process for formulation of maintenance strategies is proposed. The process is developed through a combination of previous research results, and a case study, in which three industrial organizations, participating in collaboration with researchers, have formulated maintenance strategies for their companies.

    Practical implications – Formulated maintenance strategies are the very foundation for maintenance excellence. However, many manufacturing companies lack maintenance strategies, partly due to lack of competence in how to formulate functional strategies. This paper gives example of how such maintenance strategies may be formulated requiring a low level of resource.

    Originality/value – The paper presents a work-process for formulation of maintenance strategies. The formulation process is easy to use and does not demand any larger amount of resources. Hence, it should be possible to use also at smaller companies who lack both manpower and specialist competence in maintenance strategies.

    Keywords – Maintenance, Strategy

    Paper type – Research paper

    Formulation of Maintenance Strategies2009Licentiatavhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    In industry, there is a constant demand for increased productivity in order to stay competitive. Still, Swedish industry has an average utilization of about 60% in its production systems. One important factor for increasing the equipment utilization is effective maintenance of production assets.

    Within process industry a strategic view on maintenance activities is common and most companies regard maintenance as a profit centre. Meanwhile, the discrete units manufacturing industry still in many cases view maintenance as a cost driver. However, with the spread of Toyota-inspired production concepts, the manufacturing industry is beginning to view maintenance as a strategic asset. Still, though, many companies have no formulated maintenance strategy.

    The main purpose of the research, presented in this thesis, has been to develop a work-process for formulation of effective maintenance strategies for enterprises in the manufacturing industry.

    Through one descriptive and two prescriptive case studies a work-process for formulation of maintenance strategies has been developed. The descriptive study revealed some of the differences between companies with and without maintenance strategies. It also showed how some companies view the strategic contributions of maintenance. The first prescriptive study showed how stakeholder involvement may contribute to the identification of relevant performance measures for the maintenance activities. Stakeholder involvement also contributes to the organizational acceptance of the maintenance strategy. Last, the second prescriptive case study led to the development of a work-process for formulation of maintenance strategies. The work-process was tested and verified in three companies, handling different challenges for their maintenance activities. All three companies intend to use the formulated maintenance strategy as a road map for the development of their production maintenance.

    Formulation of maintenance strategies: A simplified process2012Inngår i: International Journal of COMADEM, ISSN 1363-7681, Vol. 15, nr 3, s. 9-18Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    There is large financial potential in optimum production maintenance. Research has indicated that as much as one third of the maintenance cost is unnecessarily spent due to bad planning, overtime costs, bad use of preventive maintenance etc. However, studies have shown that few manufacturing companies consider maintenance to be a strategic area. Even among those firms that do have a maintenance strategy it is not evident that their strategies are clearly linked to the business strategies. Many companies in the manufacturing industry seem to find formulation of maintenance strategies to be difficult. To some extent this is due to lack of formal competence in maintenance management. Also companies often find the formulation process too resource demanding. Therefore, maintenance strategies are not widely used in manufacturing industry today. In addition, there seems to be no clear picture of what components a maintenance strategy could or should include. With this in mind, this paper aims at presenting a process for the formulation of maintenance strategies in discrete item manufacturing organizations. Important criteria for the formulation process are that it is easy to follow and that it does not require vast amount of resources.

    The results show that the formulation process, developed and tested in this study, has been easy to use and understand. The three case companies have found that their new maintenance strategies have given them a good picture of the present situation, as well as good guidance in their necessary improvement work.

    Maintenance Strategy - An Enabler for Improved Competitiveness2008Inngår i: Proceedings of the 18th International Conference on Flexible Automation and Intelligent Manufacturing, Skövde: University of Skövde , 2008, s. 333-339Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In order to keep production in Sweden the industry has to stay competitive on a global market. This fact increases the demand of high utilisation of automated production equipment. However, research has indicated that the average utilisation of production equipment in Sweden is about 60%. One key factor for increasing the utilisation is effective maintenance of the production equipment. Still, within the manufacturing industry, maintenance is often regarded as a cost driving necessity rather than a competitive resource. In a survey, published 2004, about 70 % of the respondents consider maintenance a pure cost centre. The same survey also revealed that 28 % of the respondents have no maintenance strategy or policy at all. The aim of this paper is to discuss the role of maintenance strategies as a means of making maintenance contribute to competitiveness. The paper is based on a theoretical overview and a case study in which six companies have been studied regarding the perceived quality of their maintenance, the challenges they face, and their view on the strategic impact of production maintenance. In the case study, four companies, which are dissatisfied with their current maintenance, are compared with two reference companies, well reputed for their maintenance excellence. The findings indicate that a strategic view of maintenance is essential for achieving the desired level of maintenance performance. This strategic view has to be held, not only by the production and maintenance management, but by the company management group. While the two reference companies have well formulated maintenance strategies, including aligned measures, acting as roadmaps for their continuous improvement of their maintenance, the four studied companies lack both strategic goals and relevant measures for their maintenance activities. The reasons for this are individual for each company but they share an insight that they need to develop their maintenance in order to stay competitive in their business areas.

    STRATEGIC FACTORS FOR MAINTENANCE IN MANUFACTURING INDUSTRY2008Inngår i: Proceedings of the 21th international congress on Condition Monitoring and Diagnostic Engineering Manangement, Brno: Czech Society for Non-Destructive Testing , 2008, s. 405-413Konferansepaper (Fagfellevurdert)
    Abstract [en]

    While the process industry has developed a strategic view of its maintenance activities and regards maintenance as a profit centre, the discrete units manufacturing industry still in many cases view maintenance as a cost driver. However, with the automotive industry as a driving force, the manufacturing industry is beginning to view maintenance as a strategic asset. Still, though, many companies have no formulated maintenance strategy. The aim of this paper is to exemplify what factors manufacturing companies consider important when formulating their maintenance strategies. As a base for this, a case study has been performed in which interviews have been conducted in six companies to find out what factors they consider to be of strategic importance for their maintenance. The results from the interviews are then analyzed and discussed in the light of some previously presented studies on the topic of maintenance strategies. The findings of the study indicate that some factors, e.g., financial considerations and spare parts handling are common for the studied companies, while others, e.g., workforce and technological level are company specific. The company specific factors may depend on contextual factors such as branch and/or company size. But which factors the companies regard as strategically important seems to depend also on the managers’ knowledge in maintenance management and maintenance technology.

    Strategic Maintenance Development in Manufacturing Industry2011Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Industrial maintenance is a substantial financial post. The total value of maintenance budgets in Europe has been estimated to be approximately 1500 billion € per year. At the same time, there are indications that about a third of these costs are wasted due to poor planning, overtime costs, inferior use of preventive maintenance and so forth. However, the diversity between different types of industry is substantial.

    While the process industry, which is rather vulnerable to disturbances, has a tradition of viewing its maintenance as a strategic resource, the picture is quite different in discrete item manufacturing industry. Historically, manufacturing industry has had a surplus of finished goods and Work-In-Progress buffers between machinery. Therefore, the manufacturing industry has been able to fulfil its production demand despite unreliable production equipment. In the last few decades, the concept of lean production has started to spread within the manufacturing industry as a means to improve competitiveness. Manufacturing companies apply lean tools such as flow oriented production layout, Just-In-Time production and Demand-Flow-Technology. As a consequence, the vulnerability to system disturbances increases and hence, the demand for dependable production equipment increases. Despite this increasing demand on reliable production equipment, few manufacturing companies work with strategic maintenance development. One reason for this may be that the existing methods and concepts for maintenance development are quite resource demanding.

    The main objective with this research is to develop a simple and cost effective approach aimed to formulate, implement, and evaluate maintenance strategies for the manufacturing industry. In five case studies the following has been studied: (1) The industry’s view on strategic maintenance development, (2) Formulation of maintenance strategies, (3) Implementation of maintenance strategies, (4) Cost of Poor Maintenance, and (5) Results from strategic maintenance development.

    As a result from this research, a process for the formulation of maintenance strategies has been developed. Further, a number of driving forces and obstacles, that influence the implementation of maintenance strategies, have been identified. The concept of Cost of Poor Maintenance has been introduced as a means for evaluating the financial contribution of maintenance. Finally, three years of studies in three companies has shown substantial benefits from strategic maintenance development.

    Strategic maintenance improvement: Driving forces and obstacles2010Inngår i: Engineering Asset Management and Infrastructure Sustainability: Proceedings of the 5th World Congress on Engineering Asset Management (WCEAM 2010), Springer , 2010, s. 789-801Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Global trade, increased levels of automation and ambitions to apply lean production increases the demand for effective maintenance of production equipment. Still, the maintenance function is often regarded as having mainly a tactical role for the assets. The fact that many companies have no clear goals for their maintenance activities is serious since goals and strategies are driving forces for increasing the maintenance effectiveness. Several studies have recognized that the absence of clear strategies obstruct maintenance development initiatives. Also, maintenance strategies should support the corporate strategy and business drivers considered critical success factors of the company. Maintenance development is the discipline of development of strategies, methods, and tools to be applied in any organization. However, well defined maintenance strategies have to be well implemented in order to contribute to the competitiveness of the company.

    The aim of this paper is to identify some of the driving forces and obstacles that have to be dealt with when implementing maintenance strategies. In the paper, three industrial cases are presented to exemplify which implications to be dealt with when implementing maintenance strategies.

    The paper is based on interviews and direct observations in three manufacturing companies in Sweden. All three companies have used the same method, within the same time frame to formulate maintenance strategies, fully aligned with their overall strategic goals. All three companies have their own specific challenges, but share the ambition to improve their maintenance programs.

    The case studies show that implementation of maintenance strategies to a large amount resembles a typical change project with all its challenges. However some of the obstacles, and also some of the driving forces are more likely to appear in the maintenance context such as the organizational and cultural barriers between the maintenance and production departments.

    The need for a holistic view on dependable production systems2018Inngår i: Procedia Manufacturing, Elsevier B.V. , 2018, s. 17-22Konferansepaper (Fagfellevurdert)
    Abstract [en]

    When discussing dependability of mechanized, discrete item production, the focus tends to be on maintenance. By studying experiences and breakdown data from eight automotive manufacturing sites in Sweden, a new view on the problem arises. It seems that on average, 40% of the breakdowns are related to poor maintenance practices. This indicates that maintenance management is not the dominant cause of breakdowns. Rather, companies should focus on human factors, e.g. skills, routines, and workload, among operators, as well as maintenance staff. Also, the Early Equipment Management process requires more attention in order to increase the dependability in the production system.

    THE ROLE OF MAINTENANCE STRATEGY WHEN MAKING CORRECT SOURCING DECISIONS2007Inngår i: Proceedings of the 20th International Conference on Condition Monitoring and Diagnostics Engineering Management, IT - Instituto de Telecomunicacoes , 2007, s. 687-695Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Today, many manufacturing companies have chosen to outsource the maintenance function, often as part of a cost reduction program. The result of the outsourcing has been successful in some cases and unsatisfactory in others. In order to make a sound sourcing decision the company needs to be fully aware of the strategic importance of the maintenance activities. Such awareness will also have an impact on the result of the chosen sourcing strategy. To assess the strategic impact of maintenance, it is essential to find relevant measurements in order to evaluate the performance and quality, as well as the profitability of the investments that maintenance activities are supposed to be. In order to be relevant, the measurements should be well aligned with the company’s vision and mission for the maintenance, which in turn should be supporting the company’s over-all business strategy.

     

    The objective with this paper is to discuss and exemplify the importance of assessing the strategic impact of the production maintenance when evaluating maintenance related sourcing decisions.  Together with a theoretical overview, this paper will present a case study performed at three companies with different sourcing solutions.

     

    The findings of the study indicate a relationship between the alignment of the over-all company strategy, the used maintenance performance measurements, and the perceived contribution of maintenance for fulfilling the competitiveness of the company. Regardless of how companies choose to source its maintenance it is obvious that a strategic view of the maintenance function will support the sourcing process by setting relevant measurements and target values for the expected performance and development of the maintenance function. One way of achieving this might be to use a model for alignment of maintenance performance indicators and business strategy.

    Identification of Maintenance Performance Indicators through consensus investigation2008Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Optimum maintenance may be expressed as: “to achieve the agreed plant operating pattern, availability and product quality within the accepted plant condition (for longevity)and safety standards, and at minimum resource cost.” But in order to achieve this, the use of performance indicators is necessary in order to evaluate both the efficiency and the effectiveness of the maintenance activities. There are numerous measures to be used for this and not always easy to select which ones to use. Several authors have expressed the need for alignment with the main organizational goals, and also the need for stakeholder involvement when identifying feasible measures. In this paper a case study is presented, in which an attempt to identify suitable maintenance performance indicators through stakeholder involvement has been performed. Except for the maintenance department, external customer, that is, the production department has been involved in expressing their expectations on the use of maintenance performance indicators. The result from the investigation, together with the expressed vision and mission of the maintenance and production department, has formed a solid foundation for establishing a feasible set of maintenance performance indicators.

    Cost of Poor Maintenance: A concept for maintenance performance improvement2011Inngår i: Journal of Quality in Maintenance Engineering, ISSN 1355-2511, E-ISSN 1758-7832, Vol. 17, nr 1, s. 63-73Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose – The purpose of this paper is to propose and discuss cost of poor maintenance (CoPM), as a concept for managing the improvement of maintenance performance within manufacturing industry.

    Design/methodology/approach – The paper is based on literature studies and two workshops

    with representatives from industry and academia.

    Findings – CoPM is proposed as a new concept for maintenance performance improvement. The concept is derived from established practices in quality costing and hence it should be easily accepted in industry.

    Practical implications – By using CoPM as a concept for maintenance performance development, manufacturing companies may identify the potential financial impact of the development work. The CoPM concept should provide a good viewpoint for identification of deficiencies in the maintenance performance within a given manufacturing system.

    Originality/value – By adopting a well-known measure from the research area of quality development, a financial measure for maintenance is proposed in this paper. The measure shows which parts of the maintenance costs are justified and which costs relate to poorly performed maintenance. In this way a more balanced view of the financial contribution of maintenance activities may be achieved, even at board level of the company.

    Downtime Costing-Attitudes in Swedish Manufacturing Industry2016Inngår i: PROCEEDINGS OF THE 10TH WORLD CONGRESS ON ENGINEERING ASSET MANAGEMENT (WCEAM 2015), 2016, s. 539-544Konferansepaper (Fagfellevurdert)
    Abstract [en]

    While the process industry, generally shows a high awareness on the financial implications of low availability, the manufacturing industry is still quite ignorant. The traditional setup of discrete item manufacturing systems has been fairly forgiving of low availability. However, by applying lean principles, the discrete item production system resembles process industry, regarding sensitivity to disturbances. Still, the awareness of the financial impact of downtime seems to be low in manufacturing industry. This is a problem since it makes it harder to justify costs for investments in increased availability. This paper presents a study of the view and attitudes towards the cost of downtime in Swedish manufacturing industry. The answers indicate that the respondents have rather vague ideas of the costs associated with downtime. Further, they rarely quantify the downtime costs that often associated with maintenance of production equipment. However, without any proper financial measures for downtime costs, the companies lack proper incentives for investing time and resources on the necessary optimization of their maintenance programs.
