Abstract: Due to the NP-complete nature of the scheduling problem of a Flexible Manufacturing System, generating a dispatching schedule to allocate resources efficiently for manufacturing of products is a complex and difficult task. It is seen that the solution is often obtained by the computer simulation which uses a dispatching rules. In this paper, we propose a Genetic Algorithm based on the Petri Net model in order to find optimal or near optimal dispatching rules under specific performance measures and restrictions. Our experiments show that the proposed approach does represent a good alternative for dispatching strategies of FMS problems.

Keywords: Petri Net (PN); Genetic Algorithm (GA); Flexible Manufacturing System (FMS).
