摘要
工作流管理系统(Workflow Management System,WMG)采用过程描述语言(Process Description Language,PDL)来精确地描述业务处理过程,即工作流,但这种严格遵照规定的静态的工作流不能自适应不可预测的外部环境的变化。在多代理系统中引入过程描述语言来制定动态的自适应的工作流,并着重描述了如何使用BPEL4WS(Business Process Execu-tion Language for Web service)作为多代理系统的规范语言来描述基于Web服务与代理的自适应的工作流。
Workflow management systems exactly enact business processes described in a process description language. But such rigorous observance of the prescribed workflow makes it impossible for the system to adapt to unpredictable circumstances. Workflow description languages can be used to specify a multi-agent system. Specifically, how to use BPEL4WS (business process execution language for web service) as multi-agents system specification language is advanced to describe adaptive workflow based on web services and agents.
