Abstract [en]

The fierce competition among the manufacturers all over the world as a result of globalisation and the dynamic atmosphere of the market has brought a new era to the production world. Shorter lead times, faster takt-times, variety of demand and products by customers, optimized inventory level, new rules and regulations legislated by governments and organizations plus efficiency of the supply chain are examples of challenges which urge companies to seek for any feasible tool which help can help to overcome the upcoming complex problems.

Recent advancements in the IT world have caused emergence of contemporary methods and tools for companies to use when confronting intricate situations to be able to handle such incidents and stay competitive in the market. Today, more companies realize the significance of change in their production system. Discrete-event simulation is one of the virtual tools used more and more recently in different areas. It is undoubtedly one of the most functional tools which could be used for different purposes in such as:

  • System learning
  • System prediction
  • Scenario planning


The application scope of discrete-event simulation is both in micro and macro levels as it can be used in a partial study of a specific process in a manufacturing company for optimization or in a higher level, to help a company to analyze its strategic plans by simulating them ahead of time.

In the current study it has been tried to investigate the application and implementation of discrete-event simulation in production. For reaching that goal, the project has been divided into two main parts; first of all a discrete event simulation has been conducted regarding a real-world potential problem. Later, by gaining the experience from the first part plus doing research around discrete simulation, it has been tried to develop a framework for industrial companies to ease the use of discrete-event simulation project process in a standardized manner.

A future prospective of the current project could be the implementation of the results and provided framework on further real-world cases and explore more innovative uses of discrete-event tool in industry. Obviously, discrete-event could be a great decision-making or analysis tool for production development if being used in the proper context. 

Abstract [sv]

Simulering är en verktyg  som möjliggör system analys billigt och lätt. När man ska simulera ett system så bygger man en model baserad på verklighet med en viss nivå of abstraktion, beroende på syftet av simuleringen. De företag som har komplicerade processer kan använda simulering som en beslutsstöd verktyg. Genom simulering av ett komplicerat system så kan man uppnå olika saker:

  • Lära om systemet
  • Förutsäga e systemets beteende
  • Scenarioplanering

När det gäller simulering så krävs två olika saker som har varit grunden för detta projektet; förmågor inom systemet som kan simuleras, kunskaper inom simuleringsteknik. Båda faktorer spelar stor roll för att ett simuleringprojekt blir framgångsrik.

Simulering har bred applikation och kan användas i olika områden exempelvis flyg simulatorer mm.

Produktion är ett område där finns potential av att utnyttja simulering framförallt ’discrete-event’ typ av simulering som för det mesta passar produktionsanalyser på grund av diskret natur av produktions verksamhet. Genom att simulera produktion eller tillverkningssystem kan man i en virtuell miljö prova kapacitet, flödet och mm.

Detta projekt har haft som mål att skapa ett standardiserat arbetssätt för användning av simulering (med fokus på DES) i produktionsutveckling. Projektet har genomförts inom Volvo CE, i Härdverket i Eskilstuna. Dessutom, det beskriver om utmaningar som dyker upp när man utför ett simuleringsprojekt genom en analys av det genomförde projektet.
