Abstract [en]

Scania CV is one of the leading manufacturer of trucks in the world. Beside the truck business Scania also manufactures buses and industrial engines. A new logistic concept at Scania means major change regarding material flow to the productions lines and today Scania is lacking a tool to analyse these material flows. The underlying hypothesis is that with a tool that could analyse logistic material flows the design of new logistic flows would be more efficient and have a better quality. A case-study was done with the tool Flow Planner and in parallel interviews with logistics engineers to find out how they are working today. The conclusion is that an analysis tool similar to Flow Planner might have a positive effect on the lead time for changing the design of material flows and could therefore be one link in the chain when striving for higher flexibility. Flow Planner can model all the different Scania standard deliv-ery methods but the output gives only a part of the information that is needed in example configura-tion of the train carts. Flow Planner can give an overview of the plant and the traffic flow within the plant. It can also contribute to more accurate risk analysis concerning the congestion of traffic in plant. A weakness of Flow Planner is that forklifts and tugger trains cannot be modelled together. A risk that was exposed during the case study is that input data has errors that will give a result that is not valid. The part of the case study that was performed with data from Oskarhamn only includes on the tug-ger train delivery of units. To get a complete picture of Flow Planners capabilities and limitations it would be preferable to make similar case-studies with real data for kit, sequence and batch also.Recommendations for the continued work is to make a requirement specification to clearly define the Scania requirements and evaluate several tools.
