RFID-Driven Graphical Method for Describing the Time-Sensitive State and Position Changes of WIP Material Flows in a Job-Shop Floor

Abstract:

The purpose of this work is to develop a graphical method for describing the work-in- progress (WIP) material flow of a workpiece in order to realize RFID-driven real-time data sampling and support following-up Auto-ID computing. Firstly, various processes in a job-shop floor are formalized graphically by using different types of state-blocks, which depend on RFID detecting spaces and tag detections. And then an event set is deduced from the connecting relations among state blocks and is used for creating the event-driven graphical model in the context of the WIP material flow of a workpiece. To verify the feasibility of the proposed method, a description case is given.
