Abstract: Now a days in Indonesia, automotive component manufacturing local companies are competing really hard. One of the component local companies is PT STLJ, it is a Make-to-Order (MTO) company that is using push production system with job shop mechanisms. In such environments, push system cannot accommodate the company’s characteristic, leads to large number of backorder and Work-in-Process (WIP). Here, an alternative system called Paired-cell Overlapping Loops of Cards (POLCA) is suggested and tested in order to give a better solution for the MTO and job shop environment. POLCA is a hybrid push-pull production system that can control the flow of material in shop floor. The objectives of this study are to describe the procedure of developing POLCA simulation model and to compare its performances with the current system. Based on the simulation result using ProModel Simulation Software, it is known that POLCA System has better performance than the current system. The number of backorder is reduced by 2%, meanwhile the number of WIP is reduced by 93%.
