Abstract: Manufactural resource scheduling relates to distributed, dispersed and concurrent data and applications. Based on workflow activities and extended Petri net, a workflow model was studied which was suitable for manufactural resource scheduling. In the model, the traditional Petri net was extended to colored Petri net and timed Petri net in order to show complex cooperation process among partner enterprises. In order to build the shared data center within the industry, the manufactural resources were integrated and the legacy systems were encapsulated by the agent technology. At same time, to show the workflow model, the manufactural resources were configured by the extended Petri-net, and the Petri-net-based workflow model was built to conduct process simulation. At last, by defining XML-based workflow process, the original system of the model was built by the developed tools of Java and Active Service Page (ASP) in the framework of Common Object Request Broker Architecture (CORBA). The study and application of the model can improve the allied enterprises efficiency of sharing resources in cross-area coordination and provide the applicable methods and theory for the cooperation of enterprises.
