为了应对来自网络计算环境下业务流程跨越协同过程中层出不穷的业务需求,提出一种基于两阶段规划模型的跨域服务流程动态构造方法.第一阶段,利用跨域服务协同语义模型,基于层次任务网络规划方法,构建满足用户业务需求的跨域抽象业务流程;第二阶段,在各域内部对抽象业务流程确定的候选服务集应用图规划数据流验证模型,构建最终的跨域可执行服务流程.方法在保证了业务需求与跨域服务流程逻辑结构的语义一致性的同时,满足了跨域服务流程中数据流的一致性,为网络计算环境下管理域间的业务协同和互操作提供了更为实际可用的可执行服务流程.原型系统实验及实例验证说明该方法的正确性和有效性.
In order to cope with the emerging business needs of business processes across network processes in collaborative processes, a dynamic construction method of cross-domain service processes based on two-stage programming model is proposed. In the first stage, cross-domain service collaboration semantic models, Network planning methods to build cross-domain abstract business processes to meet user business needs; the second stage, within the domain of the abstract business process to determine the candidate service set map planning data flow validation model to build the final cross-domain executable service process The method not only ensures the consistency of business logic and the logic structure of cross-domain service process, but also meets the data flow consistency in cross-domain service flow and provides the service coordination and interoperation between management domains in network computing environment A more practical and available executable service flow.Prototype system experiment and example verification demonstrate the correctness and effectiveness of the method.
