基于三层调度机制的工作流引擎的研究

Research on workflow engine based on three-layered scheduling mechanism

通过对工作流执行的本质的研究,根据影响工作流执行的3个基本要素对工作流过程进行逻辑上的分层,提出了基于3层调度的工作流引擎.该方法将工作流过程分成应用层、业务层和表示层,简化了工作流的执行过程,提高了工作流的柔性,增强了对复杂的业务流程应用的支持度.

In this paper a kind of workflow engine was proposed by studying the essence of workflow execution. According to three basic elements that influencing the execution of workflow,workflow process was logically separated into three layers. On this basis, a workflow engine is proposed based on three-layered scheduling mechanism. This method divides the workflow process into three layers： application layer, business-layer and representing-layer, which simplifies the workflowg execution, improves the workflow~ flexibility and enhances the support for complicated business process application.
