摘　　要：当前工业界标准的业务流程描述语言BPEL是一种集中式的编制语言,通常业务执行时由集中式引擎控制,易成为系统的性能瓶颈。提出一种BPEL业务流程解析方法,以与服务直接相关的活动为基础,将流程划分出若干基本单元,通过递归算法将其它活动归属到相关单元,产生多个子流程,实现对原有流程的分割,使业务流程可以分布式执行。实现了一个分布式业务执行原型系统,验证了解析方法的有效性。As the current industry standard, BPEL is an orchestration language. The process is under control by centralized engine, will became the bottle neck of System. Give a parse method, partition a BPEL program into several units based on activities associated with services. Classify other activities to these units by recursive algorithm, generating several sub processes. These processes can be executed by several decentralized engines. Make a distributed process execution engine prototype system. Experimental results show the method is effective.
