| Summary: | 碩士 === 明新科技大學 === 工業工程與管理研究所 === 99 === Since nowadays electronic products are innovating rapidly, the electronics industry must quickly deliver their products to the downstream customers. The passive components which are the most basic electronic components include resistor, inductor, and capacitor. So whatever the design of electronic products is simple or complex they must be used. Since inductors and capacitors are constrained by the manufacturing process, they have a limited amount of sizes or specifications. Resistors are trimmed resistance by the laser, so they have a variety of products. Because electronic products are sophisticated gradually, resistors have more specifications and make-to-stock (MTS) production mode cannot be used anymore. Instead, the assemble-to-order (ATO) production mode is used. Among the more than ten operations, there are five operations having the reentrant feature and parts must return to the same station for processing in these operations. Therefore, the priority rules of parts in this station will affect the performance of the factory. This study proposes a simulation-based research structure to evaluate the impact of experimental variables (sequencing rule in printers, manufacturing pattern of semi-finished products, etc.) on the performance of the thin film chip resistor factory. The performance indexes used in the study include total profit, number of orders waiting in printer, inventory level of semi-finished products, and flow time. Finally, a real thin film chip resistor factory is used to demonstrate the research structure. Based on the results of the case study, SRP3 (i.e., the one closer to completion is preferred) performs better with respect to the measure of total profit or flow time, while SRP1 (i.e., FCFS) performs better with respect to the measure of number of orders waiting in front of printers or inventory level of semi-finished products.
