Abstract: The production management and control are key technologies enabling reconfigurable manufacturing system, while their performance measurement is one of the most important functions that manage and control reconfigurable manufacturing system. Based on timed reconfigurable Petri nets and Gantt chart, the methodology of performance measurement is suggested for reconfigurable manufacturing system. Meanwhile, the performance measurements such as Makespan,utilization of a production resource, completion time of a job and average throughput of a part are defined for reconfigurable manufacturing system. A calculation example of reconfigurable manufacturing system is given to demonstrate the result of the performance measurement of reconfigurable manufacturing system. It is shown that the performance measurement built in this paper expresses the reconfigurable flexibilities of reconfigurable manufacturing system.
