Design Of Virtual Enterprise Workflow Process Based On Petri-net

Virtual enterprise workflow technology has call the attention of a growing number of research institutions and IT vendors as it is one of the key technologies of virtual enterprise application research. The successful application of virtual enterprise workflow will enable virtual enterprise management organization to effectively manage the entire virtual enterprise, to realize inter-enterprise workflow automation, but also to strengthen the business process coordination to a large extent between enterprises to ensure the success of virtual enterprise.There have been some typical research projects about virtual enterprise workflow at home and abroad, such as NIIIP project, CrossFlow project and VIVE project. However, there left much to be desired in these research projects of some certain aspects. In the study of the problem of virtual enterprise organizational structure design, the choose evaluation criterion of virtual enterprise members can not meet the dynamic requirements of virtual enterprise. The existing virtual enterprise workflow modeling methods show a lack of effective model evaluation system and theoretical basis in the modeling and analysis, which reduce the credibility of the modeling and analysis to a large extent. The existing virtual enterprise modeling diverged greatly from the application and implementation of virtual enterprise, especially not integrated closely with the workflow management system.The formation, definition and characteristics of virtual enterprise were firstly introduced in this paper, and then the workflow model theory based on Petri-net was analyzed. In the part of virtual enterprise workflow process design of this paper, a design proposal of the organizational structure of virtual enterprises was proposed firstly, which was analyzed and verified by using Petri-net theory and workflow network technology. Various classical algorithm can be integrated in the design proposal, as the choose evaluation system of virtual enterprise members and virtual enterprise management organization members. It can well meet the dynamic requirements of virtual enterprise as the choice of algorithm with dynamic in the design proposal. And then, the virtual enterprise workflow process model was established by the analysis of the basic framework model of virtual enterprise. The rationality of the established model was verified and evaluated based on the petri-net-based workflow theory and a higher level of standard workflow network theory. Finally, the virtual enterprise workflow management system was analyzed and implemented accoring to the analysis and design of virtual enterprise workflow process above, which put out practical exploration in making up for the disjoint between virtual enterprise modeling and application.So far, the related technologies of virtual enterprise are still in constant development and improvement, there has achieved certain results in pulling petri-net theory and workflow network technology into virtual enterprise workflow analysis in this paper, but there are still many aspects to be systematized and standardized in virtual enterprise in the future.
