This paper is to apply RFID technology to warehouse and mold management for case company and then analyze the improving result before and after introducing RFID technology and measure the performance evaluation. In this paper, firstly, the production processes of case company are analyzed to realize the production model and time consumed by each process. Secondly, a simulation experiment is conducted for performance evaluation. The research results showed that manpower cost is dramatically reduced after the RFID technology was introduced in the case company; and that the RFID system effectively decreased the rate of negligence arisen from human error and moved up the whole benefit and operation and competitive force for case company.
