Gaining Competitiveness Trough Understanding Critical Factors Affecting the Production System : A Case study in cooperation with GKN Driveline Köping AB / Skapa Konkurrenskraft genom Förståelse av Kritiska Faktorer som påverkar Produktionssystem : En fall studie i samarbete med GKN Driveline Köping AB

Rosén, Jan-Peter, Haukirauma, Kari January 2013 (has links)
Globalization and the increasing time to market have led to ever-higher requirements on the production systems. More than often the short-term thinking and the chase for profit lead to cheap quick fixes. The manufacturing industry changes slowly while the market is changing rapidly, which requires long-term planning for capacity increase but at the same time the ability to rapidly respond to changes. The most crucial factors determining the ability to efficiently produce and deliver a product to market is the utilized production system and a well stated manufacturing strategy. The choice of a certain production system depends on company conditions and requirements as well as the market demands. The current production systems performance and ability to handle different production volumes and divergence must be considered and evaluated from an economical perspective. During this thesis work the benefits and disadvantages with batch flow and one-piece flow have been examined. Generally one-piece flow had been considered the most efficient regarding performance and economical aspects. Meanwhile, batch flow had some benefits associated to it regarding high level of flexibility to handle several different product variants and better possibilities to govern the material flow compared to one-piece flow. There has also been examined which are the most crucial factors affecting the choice between one-piece flow and batch flow. It emerged during the thesis work that the most crucial factor affecting the choice of production system was the Manufacturing Strategy. It can be considered as the ground for every decision regarding the production system and future investments. It determines where the company currently stands, where they want to be in the future and which steps they need to take to get there. The economical factor is as least as important because all decisions include more or less costly investments. At the same time the chosen production system must be as efficient as possible and generate money for the company. Based on these two main factors other interesting factors have been presented. These factors may not affect the choice as much, but are to be considered as important in this context The most crucial factors found to affect the choice of a production system were; Manufacturing Strategy, Economical factors, Production planning and control, Flexibility and capacity, Production volume, variants and trends. The research work has been conducted over a twenty-week period, during which data collection has been performed via Multiple Case Studies at four companies manufacturing similar components within the light and heavy automotive industry. Additional data collection has been performed through a literature review by examining relevant material for the research questions. This have led to a collected knowledge base regarding benefits and disadvantages with each production system along with underlying reasons for deciding on one of them. Based on the collected material from the Case Studies and the theoretical findings, a Mind map visualizing the crucial factors affecting the choice of a production system is presented. This can be utilized by the companies in order for structured evaluation of their current production system and for planning for future changes within production. / Globaliseringen och den ökande pressen på företag att producera och få ut produkter på marknaden på kortast möjliga tid har lett till att det ställs allt högre krav på produktionssystemen. Allför ofta leder kortsiktigt tänkande och jakten på vinster till att företag väljer enkla och billiga snabblösningar. Tillverkningsindustrin förändras långsamt medans marknaden ändras fort, vilket kräver att företagen kan planera för långsiktiga kapacitetsökningar och ändå ha beredskap för att snabbt kunna anpassa sig till förändringar. Det som till allra största del avgör hur effektivt man kan producera och leverera en produkt till marknaden är vilket produktionssystem ett företag använder samt en välformulerad tillverkningsstrategi. Vilket produktionssystem man väljer är beroende av vilka förutsättningar och krav ett företag har lika mycket som av marknadskraven. Man måste ta hänsyn till det nuvarande produktionssystemets prestanda och möjlighet att hantera ändrade produktionsvolymer och variantflora och utvärdera detta ur en ekonomisk synvinkel. Under detta examensarbete har för- och nackdelar med batchflöde och enstycksflöde undersökts och utvärderats. Generellt sätt har enstycksflöde konstaterats vara mest effektivt rent ekonomiskt och prestandamässigt. Däremot, har batchflöde tilldelats fördelar som hög flexibilitet att hantera olika produktvarianter och bättre möjligheter att styra materialflödet jämfört med enstycksflöde. Det har även undersökts vilka som är de mest avgörande faktorerna som styr valet av enstycksflöde eller batchflöde. Under arbetets gång framkom det att den mest avgörande faktorn som påverkar valet av produktionssystem var företagets Produktionsstrategi. Den kan anses vara grunden för alla beslut rörande produktionssystemet och framtida satsningar. Där visar man var företaget befinner sig idag samt var man vill vara i framtiden och vilka beslut man måste ta för att ta sig dit. Den ekonomiska faktorn är minst lika viktig, då alla beslut i slutändan handlar om mer eller mindre kostsamma investeringar. Samtidigt måste det valda produktionssystemet vara så effektivt som möjligt och generera pengar till företaget. Med utgångspunkt från dessa två huvudfaktorer har andra intressanta faktorer tagits fram, som inte påverkar valet av produktionssystem i lika hög grad, men som ändå kan anses vara viktiga i sammanhanget. Forskningsarbetet har bedrivits under 20 veckors tid, där datainsamling har utförts via fallstudier på fyra företag som tillverkar liknande komponenter inom fordonsindustrin. Vidare datainsamling har gjorts genom en litteraturstudie där relevant material för forskningsfrågorna har undersökts. Detta har lett till en samlad kunskapsbas gällande för- och nackdelar med de respektive produktionssystemen samt bakomliggande orsaker till att välja något av dessa produktionssystem. Utifrån det samlade materialet från fallstudierna samt de teoretiska rönen har sedan en tankekarta tagits fram, som visualiserar de avgörande faktorerna som påverkar valet av ett produktionssystem. Denna tankekarta kan företag använda sig av för att på ett strukturerat sätt utvärdera nuvarande produktionssystemet samt planera för framtida förändringar inom produktionen.
