【 摘 要 】

The layered workflow process model provide a modeling approach and analysis for the key process with Petri Net. It not only describes the relation between the process of business flow and transition nodes clearly, but also limits the rapid increase in the scale of libraries, transition and directed arcs. This paper studies the process like reservation and complaint handling information management system, especially for the multi-mergence and discriminator patterns which can not be directly modeled with existing synchronizers. Petri Net is adopted to provide formalization description for the workflow patterns and the relation between Arcs and weight class are also analyzed. We use the number of in and out arcs to generalize the workflow into three synchronous modes: fully synchronous mode, competition synchronous mode and asynchronous mode. The types and parameters for synchronization are added to extend the modeling ability of the synchronizers and the synchronous distance is also expanded. The extended synchronizers have the ability to terminate branches automatically or activate the next link many times, besides the ability of original synchronizers. By the analyses on cases of the key business, it is verified that the original synchronizers can not model directly, while the extended synchronizers based on Petri Net can provide modeling for multi-mergence and discriminator modes.
