Design and Implementation of Workflow Engine for Process Planning Based on GSPN

In order to implement flow management of process planning and meet the process information requirements in manufacturing enterprises, workflow technology was introduced to analyze the activities of process planning. It was extremely important for workflow modeling of process planning. Based on the flow analysis of process planning, the modeling generalized stochastic Petri nets (GSPN)-based was proposed. The relationship of actual process planning and the elements of GSPN were studied. Workflow engine as the core of the whole workflow system supplied the system execution environment, so the design and implementation is the key of the system. The design method and development flow of workflow engine were discussed based on JBOSS JBPM. Finally, a workflow system of process planning based on the model was developed, which greatly improved the flow management capability and the efficiency of process planning.
