The Architecture Of Workflow Management System Based On Tree Layers Scheduling Mechanism

Information technology have already deeply entered into human society, almost all organization (the government, enterprise, group etc.) all need the supports of information system. The appearance of workflow technology provided advanced method and technology means to structure information system. Today, the research and application of the workflow technology have already got very big successes, the workflow management system product is also contention of a hundred schools of thought, and each has its advantages.Workflow separates process logical from the application to make information system be absorbed in business application, not considering the complexity of process logical. Process logic is the process of multi-agent Real-time collaboration, the agent's decision decided process's trend and route. But, object—the special business data and the relevance data of workflow affect the agent's choice. The process definition that abstract from business process is the real reflection of business process, also is the restriction of agent's decision. The agent, object and process definition influence each other, restraint each other, composes the basic element of the workflow execution. That tradition workflow management system does not design by the essence of workflow, but commix the three element,repeats execution, that must increased the complexity of achieve workflow manager system, and short of the flexibility to handling complicated business process.So that, this paper put forward the architecture of workflow management system based on tree layers scheduling mechanism, come true by differentiate the affection of workflow's three basics element, and divide it into three layers. This system simplified workflow's execution, improved the workflow's flexibility, improved the support of the complicated business process application. This system has already applied to Harbin Engineering university's "magic zero-coding software produce platform" successfully.
