This study aims to improve the KPIs of manufacturing plants by benchmarking an FOM model. This involves designing a scheduling algorithm for the shop floor; developing and testing a simulation model that reflects information such as equipment, orders, and process times identical to those of the factory; and selecting a scheduling algorithm that is appropriate for the factory. To this end, we designed the architecture (framework) of the information exchange and performance evaluation process between the MES, what-if simulator, production operation information, KPI, rule tuning, and advanced planning and scheduling (APS), targeting factories of domestic PCB manufacturers. Consequently, several scheduling methodologies were found, which improved the KPIs (lead time, tardiness, equipment utilization, and productivity) compared to the scheduling methodologies currently used in the process.
