Today, simulation studies have found many applications in industrial engineering and other sciences. In today's competitive market, companies and organizations are trying to increase productivity and efficiency by designing and modeling effective and efficient system operations. In this regard, to reduce evaluation time and reduce costs, use similar methods. Graphic construction in software environment and the use of statistical software are instructive and efficient. The purpose of this research was to reduce costs, increase production, reduce the unemployment time of operators and machines, as well as reduce inventories between the production processes. Simulation was used to achieve these goals. The steps of conducting the research are summarized as follows. First, the layout in the factory was identified, in the next step, timing was done for the devices and operators. Real data was transferred from the production line to the software environment and then 15 different scenarios were designed and simulated in the software environment. Then, using TOPSIS method, the best scenario was selected and using the experts and factory managers, the validity of the model was confirmed and then the model Execution and simulation results were recorded.
