一种面向服务体系结构的服务组合方案求解方法

摘要

The emergence of service-oriented architecture provides a solution for distributed applications enterprise. How to quickly find the concrete service or the composition solution is the burning issue. According to the input and output of abstract service and some function properties, the process work of the abstract service composition was constructed, and then proposed an approach of solving for service composition program, which based on semantic Web service and figure planning, in order to refine the abstract service. In the refinement process, Web services were mapped to the formal description of the action plan, reasoning out the Web service composition programs. It made full use of service similarity to choose concrete service and program optimized. At last, the simulation experiments show the effectiveness of the method.%面向服务体系结构的出现为分布式应用集成提供了一种解决方案,如何快速准确地指定具体服务或求解出服务的组合方案的问题尚待解决.根据对抽象服务的输入/输出等功能性属性的描述,完成了抽象服务组合流程建模,为了对抽象层粗粒度服务的求精,提出了一种基于语义Web服务和图规划技术的服务自动组合机制,该方法将Web服务映射为规划动作的形式化描述,形式化推理得出Web服务的组合方案.在具体的服务或方案选择上,利用服务相似度优化服务或服务组合方案的选取.最后通过模拟实验验证了该方法的有效性.
