摘　　要：以业务流程执行语言(BPEL)为基础,选取无状态的Web服务,采用有色Petri网模型描述业务流程,设计一种多输入多输出、引擎集中式的流程执行结构,使用关联矩阵和消息的双向传递实现应用级的状态保存。当流程异常中断时,提供恢复执行所需的最小状态集合,保证基于Web服务BPEL的面向服务架构应用的正确性和连续性。实例分析表明,该方法实用性强、可靠性高。Based on Business Process Execution Language（BPEL）,this paper adopts stateless Web services and describes business process as Colored Petri Nets（CPN）,which designs a Multiple Input and Multiple Output（MIMO） process running structure in the centre of engine,using associated matrix and bidirectional message transfer to do application-level state preservation.When the process is interrupted,the engine provides a minimum set for state recovery.It makes the Service-oriented Architecture（SOA） process based on Web Services BPEL（WS-BPEL） accurate and continuous.Example analysis results show that this method has good practicability and high reliability
