Abstract [en]

Purpose: The purpose of this study was to analyze possible strategies that can be used to improve the efficiency of the spare parts safety stock management in a multinational company which operates in the electronic industry.

Research question: “Which safety stock dimensioning strategies are most suitable in an after-sales business environment, characterized by high level customer service and unpredictable demand?”

Method: The theoretical framework illuminated the study’s phenomenon which was mainly based on peer-reviewed scientific articles but also academic books. Furthermore, the empirical data collection in this study was conducted through a mixed research approach, where the qualitative data was collected through three semi-structured interviews and several unstructured interviews, while the quantitative data consisted of calculations using numerical variables provided by the case company.

Conclusion: The study concluded that the so called estimated safety stock method as well as the probabilistic demand based on history method are the most suitable safety stock dimensioning strategies to utilize in business environments where firms that offer products with unpredictable demand are facing challenges related to finding a balance between providing a high service level and keeping their costs as low as possible.

Abstract [sv]

Syfte: Syftet med denna studie var att analysera möjliga strategier som kan användas för att förbättra säkerhetslagerhanteringen av reservdelar hos ett globalt företag inom elektronikindustrin.

Frågeställning: “Vilka dimensioneringsstrategier för säkerhetslager är mest lämpliga i en eftermarknadsverksamhet, kännetecknad av hög servicenivå och oförutsägbar efterfrågan?”

Metod: Det teoretiska ramverket belyste studiens fenomen som var baserad på främst expertgranskade vetenskapliga artiklar men även böcker. Vidare genomfördes den empiriska datainsamlingen i denna studie genom en mixad forskningsmetod, där den kvalitativa datan var i form av fyra semistrukturerade intervjuer samt flera ostrukturerade intervjuer, medan den kvantitativa datan bestod av beräkningar med hjälp av numeriska variabler tillhandahållna av fallföretaget.

Slutsats: Studiens slutsatser visade att den så kallade manuellt bedömt säkerhetslager metoden samt probabilistisk efterfrågan baserad på historisk data metoden är de mest lämpliga dimensioneringsstrategier för säkerhetslager att använda i affärsmiljöer där företag som erbjuder produkter med oförutsägbar efterfrågan står inför utmaningar relaterade till att hitta en balans mellan att tillhandahålla en hög servicenivå och att ha så låga kostnader som möjligt.
