基于代理的工作流邦联及子流调用框架

在分析层次工作流建模和工作流执行时互操作研究的基础上,设计了一个基于代理的邦联及子流调用框架,将层次化建模技术、流程互操作技术和异构数据模型映射和转换技术集成在一起,同时提供了异常处理和灾难恢复功能,真正从业务层次上解决了流程协作问题,并在TiPLM2.9上实现了该解决方案.流程实例之间通过代理进行交互,各个流程独立运行在自己的工作流引擎中,实现了松耦合和隔离性,增强了系统健壮性.

An Agent-Based Framework to Support Workflow Confederacy and Subprocess

Based on the hierachical workflow modeling and workflow execution interoperation,a framework is proposed for supporting workflow confederacy and subprocess based on agent.This framework not only takes the hierachical modelling,process interoperation,heterogeneous data model mapping,translating technology into consideration but also provides the capacity of exception handling and disaster recovery.The framwork on the system TiPLM2.9 is implemented,which solves the practical problem of process cooperation from the business point of view.In this framework,process instances use agents to interact with each other and each process instance still works independently on its own workflow engine as usual,which realizes the loose coupling and isolation,and improves the system robustness as well.
