RFID for MRO Work In Progress Tracking

The aerospace maintenance, repair and overhaul (MRO) operation is a dynamic business. The job scope is unpredictable and there are also other challenges such as urgent orders that upset the production plan. As a result, the planner needs to make prompt decision to adjust production plan from time to time. To do this efficiently, the availability of timely and accurate work-in-progress (WIP) information at the shop floor is critically important. The traditional practices of paper based WIP tracking are tedious and inefficient. This paper discusses a novel approach of using the rewritable RFID tag as a means for electronic job order that overcomes the shortcomings of the paper based tracking
