Design and implementation of discrete manufacturing industry MES based on RFID technology

Considering the discrete manufacturing features and the production management problems caused by information and management gaps between Enterprise Resource Planning(ERP) plan and field process control,Radio Frequency IDentification(RFID) was introduced into the Manufacturing Execution System(MES) for discrete manufacturing,in which tags were used to track Work In Process(WIP) and the system was compatible with bar code technique in some cases.Shop controller and station controller collaboratively delivered the production plan and collect the field production real time data.Data integration and operation integration between MES and ERP were fulfilled through system integration interface.Thus visualized and digitalized management of manufacturing and quality were realized.System structure and major functional modules were characterized by its favorable openness and extensibility.Its application in a gasoline engine assembly line showed that both production efficiency and quality were greatly improved.
