Abstract [en]

Gestamp HardTech is a world leader manufacturer of safety components for the automobile industry. By press-harden components like side impact beams and B posts it is possible to give the customer the desired qualification needed for the car. The product needs to go through a couple of processes before it can be sent to the customer. Step one in the process is to be pressed, press-hardened, shot blasted and finally laser cut at the last station. This study is carried out on basis of the company’s need of an up to date and standardized analysis method that the company could use when deciding wherever or not to start producing a component. The company also seeks the possibility to give a deeper understanding of a product flow and visualize bottlenecks through product simulation tools. The goal of the study is to give the company an understanding over the positive sides of a production simulation tool. This project also features a standardization of a well known analyzing tool called, value stream mapping. Gestamp HardTechs previously made analysis where not up to date and was in need of a re-establishment with new improved data variables. With a new improved adapted analysis data could be collected from August and November which could be broken down and analyzed. Office Visio 2007 was used as tool for the value stream mapping. The result shows that August was a month with low production in comparison to November where the OEE was greater. The result from the analysis was later on used as template for the simulation study in order to generate as authentic simulations as possible. Four different situations were tested; prognosis, halved campaign (HC), pulling system + HC and increased demand by 50 percent. Prognosis was based on assumptions of how the production would look like during the end of year 2010. Simul8 was used as simulation program where the simulation time has been set to 11 weeks with a warm up time of three weeks in which the result wasn’t being gathered. By using the function trials a list of wanted data could be gathered and analyzed. In order to develop the result further on some data were automatically sent to an Office Excel 2007 document in which it could be seen as graphs for products at work and products produced per week. The result shows that a pulling system contributes to a smoother and more continuous flow with a great reduction of products at work and time in system. Tests for a increased demand of 50 percent shows that laser station 6 has reached its maximum level of production which means that it is the systems bottleneck. An action plan has been set up based on the result in order to give the company an understanding of what they should do to make their production more efficient. The plan is being introduced in a way so that the company knows what to prioritize before they can go on to the next step in the action plan.
