Building a dynamic value stream mapping

Value stream mapping (VSM) is a visualization tool helps to understand processes by using of stream lined work process. The importance of this process is to decrease the activity that does not add value to the final product and in order to increase the efficiency and production. The purpose of this thesis is to create dynamic value stream maps of a process by using simulation. By creating dynamic value stream maps makes it possible to analyze more complex systems than traditional VSM. Simulation can be used with value stream mapping to give it power and flexibility in order to dynamically change the state of the system. The spiral welding production line has been working for many years. The company is facing an increase in the demand along with possibilities of later product development so that they could get more efficiency, less costs, higher quality, and a dynamic workforce plan according to the varying demand. This cannot be achieved unless studying the process inside out and finding new areas that have the potential for improvement. In this thesis I have tried to investigating these areas and the focus is on finding solutions for improving them. This thesis work performs at the production process of spiral welding steel plates for analysis the buffers, calculate cycle, process time and reduce waste by using VSM and DVSM. It has been trying to provide readers with a clear prospective of the company, a precise analysis on the mentioned production line and apparently areas of improvement in the production process
