Abstract
In this paper, we propose a new method of quality control using traceability system based on RFID (Radio Frequency Identification) technology. This method consists of following procedures. A RFID chip is attached in all unfinished products before the first process. In middle processes, the inspected result is stored in the chip. The information stored in a tip is taken out after the last process. Quality is judged based on the information about all products. Nonconformity goods are eliminated based on the result of the judgment. If a supplier adopts this method, most nonconformity goods will not be shipped from the supplier. In this paper, we consider a possibility that a supplier will adopt this method.
