Services Process Implementation Based On Jbpm And Workflow Model Transformation Technology

The paper study two aspects: On one hand ,how to implement service process based on JBPM is discussed. It gives some concept about work flow ,and makes some research about workflow reference model and structure of workflow management system. Based on norms proposed by WFMC and analysis about workflow, the paper presents six elements of workflow model: order model, and the branch model, and the connection model, or the branch models, or the connection model, cyclic model . After it discusses the workflow-related information, this article analysis working principle and core structure of JBPM. At last , it makes examples for illustrating the operation process of JBPM process. Based on the analysis of workflow and principle operated by workflow engine, the paper researches service process and implementation of service process, and makes functional requirements of the campus ordering services and service processes . then it proposed packaging needs for the JBPM workflow engine. The paper analysis how to design and improve work flow engine, in order to meet the needs of the process by service package, finally it verified the design and analysis is correct by a school ordering cases.On the other hand, paper makes study about conversion of workflow model. First, it analysis the definition and methods of model transformation and propose design for transformation from platform-independent model to platform specific model based on analysis and study of these conversion methods. It analysis elements conversion from ICEMODEL to JBPM model based on the ideas of studys, and makes the definition of grammar rules for the conversion of these elements, then summarized the general definition of model transformation rules. It design the the convert engine structure based on the analysis and design of the model transformation rules. Finally, the paper verified the JBPM workflow engine research by makes example of campus service platform .It present the structure workflow engine and makes study about the model instance of the workflow model and management mechanism and To-do tasks mechanism. Then it verified the syntax rules by transformation from ICEMODEL to JBPM model .
