Research and Application of Lightweight Workflow Engine Kernel

A workflow engine with high performance firstly depends on a good structure engine kernel, secondly on the extensibility of function. At present the research of workflow engine focuses on execution of complex business flows, emphasizes application compatibility too much, however, neglects the structure design of engine kernel from an abstract angle. A lightweight workflow engine kernel is designed from the most fundamental question, namely how to execute task nodes one by one in-order. Meanwhile stability and extensibility of engine kernel have shown the feasibility and validity through implementation in a small and medium manufacturing enterprises.
