hela Sverige Scania is now undergoing a transformation from being a supplier of trucks, buses and engines to a supplier of complete and sustainable transport solutions.
Background
Production capacity calculations are of great importance for the optimization of future production capacity. Today this is done every year with a 5 year forecast using the global market demands as a basis. The demand is broken down from complete vehicle to individual part numbers, and further distributed among the machine lines which are capable to produce them. Key factors affecting the production capacity is the bottle neck of the machine line i.e total cycle time, possible buffers and their size and position in line, process planning, batching of articles and overall production efficiency (OPE), to name a few.
One machine line can be capable to produce more than one individual part creating a mixture. This kind of machine lines usually have a varying bottle neck that can be affected by other key factors, like the composition of the mixture, process planning, buffers and so on.
Previous simulations have been done to obtain the theoretical maximum OPE and capacity for a machine line producing output shafts, a part in the gear box of a Scania truck. This line is now a continuous line flowing all the way from raw material to finished part ready for assembly. At this time new articles are being introduced giving a great opportunity to implement new strategies to reach maximum capacity. We are now interested in further investigations on how the theoretical maximal OPE and capacity is affected by different factors and how these impact each other. To take this one step further we would like to simulate not only the traditionally varying factors from the normal production cycle, but also investigate alternatives "outside the box" like how decoupling of the machine line can affect the OPE and capacity for the entire line as a whole.
Effect and Product goal
The goal of the project is to find the theoretical maximum capacity and OPE for the output shaft machine line at Scania and further analyse the results. The project should consider a wide range of scenarios, including alternative solutions, like decupling, new buffer stations etc.
The project should
• Describe the dynamic in the current machine line.
• Simulate different production line scenarios.
• Compare the current machine line to the most promising alternatives accordingly to simulations.
• Describe key actions for increased capacity of the machine line in both short term and long term actions.
Simulation will be done using ExtendSIM and the previous verified model created for this machine line.
