In this study, we examine the application of Tecnomatix Plant Simulation software in simulating and managing the production processes of businesses. Starting from an initial model of a production packaging assembly line, we utilize Tecnomatix software to calculate the efficient performance of each machine and workstation. The research also demonstrates the level of influence when adjusting the parameters of equipment and machinery, thereby providing suitable adjustment options to address production line issues and achieve higher output. As a result, we improve the factory model, alleviate bottlenecks in the production line, and enhance overall plant management. Specifically, we have increased the efficiency of the factory by 230% compared to before the adjustments.
