For many companies today a growing number of products as well volumes paves the way for new challenges. The development today forces companies to make rationalizations within operational activities to enhance the competitive advantage in a more violent market place. At the same time companies must rearrange activities and at the same time achieve the wanted performance. However, these challenges has been approached in this thesis through creating a framework that proposes a new Material Supply System that enables companies to still become competitive when supplying material to assembly stations. This thesis has furthermore filled the gap of earlier researches regarding of considering the whole Material Supply System instead of only concerning the in-plant section of a Material Supply System. The necessity to consider the whole Material Supply System can be explained through the supplier related contextual factor that has been elaborated within this thesis. This is essential when dealing with circumstances that aim to create the best possible conditions for the assembly station when fetching parts, since decisions back in the chain has an impact of how the material can be presented at the line. Furthermore, the framework considers the whole view by not sub optimizing when designing the new Material Supply System. Many other approaches only use to optimize on local level and hence this study expands the current research by using an approach that optimizes on a global level to achieve expected performance for the whole setting. However, to carry out the framework 61 different information sources (articles, books, brochures, websites etc.), interviewing respondents within two different companies and best practices from internal databases has given the result of this framework. As a result, the creation process has been a complex process from the beginning to shape the end result, where many different interrelations between theories have been connected to a finished framework. The second purpose was to apply the framework within the context of Volvo CE and according to the result it provide opportunities for Volvo CE to reduce the inventory levels within the plant by pushing back inventories to a third part provider, decrease the material handling, eliminate the use of forklifts, create more smother and straighter flows from the supplier, better presentation of the material for the operators etc. However, the whole approach to define the Material Supply System has been iterated through the approach by defining a Material Supply System in accordance with a whole view perspective. Thereby, the two performance areas suggested by Volvo CE; decrease the inventory levels respectively enabling better ergonomically conditions has been attained.
