Developing real-time manufacturing execution system for automobile assembly factory

With the enhancement of the modern automobile manufacturing capacity, Takt time becomes shorter with the growth of automobile production, product configurations become more diverse with the increase of customizing requirements, traditional data acquisition methods and manufacturing resource identification methods cannot meet the need of manufacturing execution system (MES) in job shop scheduling, work in process (WIP) tracking, rapid response of process control and so on. As an automatic identification technology, Radio Frequency Identification (RFID) can be applied to bridge the gap between physical flow of product/part and information flow in enterprise application system due to its characteristics such as automatic identification, long-distance reading, and non-line-of sight. Based on this characteristic, this paper design a real-time MES (RT-MES) for automobile production and successfully implements this system based on the actual situation of JAC.
