A NEW RFID-BASED RTLS FOR DISCRETE MANUFACTURING WORKSHOP

摘要

The research is concerned with the practical use of RFID-based traceability approach in large discrete manufacturing workshop. An RFID-based RTLS (Real-time location system) is proposed for tracking WIPs (work in processes), Tool, Measuring tool, and AGV to achieve new levels of process visibility and control. The positioning methods and principle are introduced and the framework of the proposed system is provided. A prototype system is developed to verify the proposed system and a simulation model is built to evaluate the performance of the proposed system. The results indicate that the proposed system generates better performance compared with traditional system with regard to cycle time and machine utilizations, especially when some disruptions occur.
