Abstract

Flexible manufacturing systems (FMS) are a class of systems exhibit- ing concurrency, asynchronicity and distributedness. In this project the Petri net is incorporated along with discrete events simulation to simulate scheduling different types of job processes in FMS. In order to get high throughput and uniform loading on each station in FMS, a Large-sized Petri Net ( LPN ) model has succeeded in finding all the possible process sequences for jobs in FMS. The SIM SCRIPT language is used to find, for each job, the state of each workstation in all possible sequences and then to select an optimal sequence for doing the job. In contrast with relying on static optimization, in Petri net scheduling we are able to find the online optimal sequence dynamically. The results suggest that Petri net schedul- ing ca
