基于XPDL的工作流引擎研究与实现
摘要
本文旨在研究基于XPDL的工作流引擎的应用与实现。文章首先介绍了工作流管理系统的相关理论和技术，并介绍了工作流管理系统的研究现状和应用情况。然后集中阐述了工作流元模型和工作流过程定义语言XPDL，重点分析了工作流引擎的理论和核心调度机制。接着介绍了作者所在科研团队自主研发的工作流管理系统RRFlo的体系结构及功能组成，详细描述了RRFlo工作流引擎—RRFloEng的设计与实现工作，同时描述了RRFloEng在上海汽轮发电机有限公司的应用情况。最后在论文的总结中，提出了一些有待改进的地方以及对后续研究的展望。
The aim of this thesis is to research and realize the theory of workflow engine based on XPDL defined by WfMC. Firstly, the paper introduces the development of workflow technology and relevant conceptions. Then the paper gives the details of XPDL and workflow meta-model, and analysis the core mechanism of workflow engine. RRFloEng, the engine of RRFlo, is designed and implemented with the technologies of J2EE and XML while it describes the application of RRFlo. Finally, in the summarization of the thesis, the prospect and possible improvements are discussed.
