RFID應用於自動化物料資訊管理之研究-以TFT-LCD模組廠為例

Abstract

A thin film transistor liquid crystal display (TFT-LCD) is the top output property in Taiwan, which is also the major supplier to the entire world. The after-production of TFT-LCD module factory is going through a Make to Order system. That is to say, physic supplies of a module factory will be distributed to three major distributions — purchase, production and shipment. Therefore, how to reduce the time of physical distribution for the module factory to cut down the lead time of production has become one of the most competitive conditions among the TFT-LCD industries. According to the interviews with some cases and documental researches, we have come to analyze the reason why nowadays the time of physical distribution delays is because the data inspection of physical supplies from receiving orders to shipment is being processed and controlled by manpower and bar-code document. Our research believed that the length of inspection and process towards physical supplies will be the major factor for physical distribution. Therefore, we bring up the idea that the inspective system of receiving, production, quality and shipment should be integrated with the data of physical supplies on the spot and the data of enterprise controlling system. The concept of the integration used in the research is to integrate the technique of Radio Frequency Identification (RFID) with the system of Enterprise Resource Planning, then customize a module of automation management of material information. Module is applied to the examination of materials and supplies in the module factory. The altering information of materials and supplies will be shown on the information system based on the RFID system; consequently, the examination can be grasped immediately. The result shows that there is an evident effect of shortening for the logistic time for materials and supplies. As the more materials and supplies are examined, the more evident shortening of logistic time would be.
