Study Of Web Service Workflow Based On Petri Net

Along with the development and extensive application of Web services technology, the research of Web services integrated technology has gradually become the key question in Web services research. Through Web services integrated technology, single Web services can be assembled to be strong function and complex structure Web services.The work current theory research is a way to optimize the work: That is forming cooperate and achieving optimal through strengthen correspondence and communication between each working, as an important mechanism of assemble Web services, it is very important to establish the Web services with new and strongly function fast. As system model, Petri net has rigorous math foundation and graphics modeling ability, it be widely applied to modeling and analysis of disperse event dynamic system (DEDS), such as distributional software system, and so on.This article studies the related technology emphatically which the Web services integration workflow, namely how to combines the Web services integration workflow from the single Web services, become Web services flow and flow pathway modeling using Petri net. The article finally gives an example of Web services current application based on Petri net. The example mainly show the function analysis and design of Web services flow model aimed at Meiling's ordering module of internet selling system, and realize the internet order, transfer system that manufacturer as centre , marking distribution and bank system participate together .
