This project delves into the optimization of facility layout in a metal fabrication plant through the application of discrete event-based simulation and Systemic Layout Planning (SLP), aiming to enhance production efficiency. This case study endeavor sets out to better manufacturing performance at Progressive Metal Manufacturing Company (PMMCO) in Warren, Michigan, with the guiding principles of lean manufacturing, aiming to strengthen its production system. Employing an array of lean tools such as optimization, statistical process control, process mapping, flow optimization, 5s, and Muda’s 8 wastes. The primary objective is to identify an optimal plant layout that maximizes machine utilization and execute an ideal solution for space allocation. Analyzing the different sequences of operations and cycle times for each metal fixture product will be key inputs for the applied plant simulation. PMMCO is identified as a high-mix, low-volume job shop, splitting operations into two facilities. The existing plant layout holds several limitations on manufacturing production due to the machine quantity in the plant and current spatial relationships. The new layout considers four new machines to be relocated from one facility to the other, expanding the range of operational abilities in the Warren facility.
