Abstract: The execution reliability of business process is an indispensable problem in workflow management research. However, there exists the need to solve the death problem of mobile agent in the concurrently coordinating process. Based on migrating workflow model, a reliable execution model of migrating instance is proposed. The model can achieve different levels of implementation of the main monitoring and failure diagnosis and treatment of the monitoring of the design. In addition, the model itself is removable, can be replicated and automatically quit, thus the accuracy of the inspection and efficiency of monitoring can be ensured. Experimental results indicate that the model possesses reliability and low cost and scalability, especially is suitable for the concurrent execution situation in the inter-organizational environments.

摘要: 当前工作流管理中,业务流程执行的可靠性是一个不容忽视的重要问题,然而,现有的研究在解决多主体协调并发执行过程中的主体夭折问题存在不足。基于迁移工作流模型,提出一种多迁移实例的可靠执行模型,模型可以实现不同层次上的执行主体监测与故障诊断和处理;同时设计守护实例具有可移动、可复制以及自动退出等特点,有效提高了检测准确性和监控效率。实验表明,模型具有高可靠性和低开销以及可扩展性等技术优势,特别适合当前跨机构环境中多主体的并发执行。
