主 题:GA Petri net Deadlock-free scheduling
摘 要:An efficient algorithm for finding an optimal deadlock-free schedule in amanufacturing system with very limited buffer is presented. This algorithm is based on the effectivegenetic algorithm (GA) search method, and a formal Petri net structure is introduced to detect thetoken player assuring deadlock-free. In order to make the scheduling strategy generated by GA meetthe required constraint of deadlock-free, Petri net is involved to make the implementation of thejob scheduling in an FMS deadlock-free. The effectiveness and efficiency of the proposed approach isillustrated by using an example.
