摘要: 结构健壮性判定是服务组合领域的一个重要研究问题。已有研究成果通常仅对健壮性进行定性分析,难以精准对服务流程的结构质量进行评价。针对上述问题,本文提出一种基于Petri网的结构健壮性的层次评价方法,建立4个层次的服务流程结构健壮性划分准则,并给出相关判定算法。最后,以网上在线交易服务流程为背景,构建不同级别结构健壮性的流程算例,例证了所提出方法的可行性。

Abstract: Determination of structure soundness is an important research issue in the domain of service composition. The existing research focuses qualitative analysis of structure soundness and cannot accurately evaluate the structure quality of service processes. To address such problem, a hierarchy evaluation method for structure soundness based on Petri net is proposed. The four-level divided principle of structure soundness for service processes is put forward and its determining algorithm is also presented. Finally, application instances with the background of online-trade service processes are given to show how to judge the different level of structure soundness and the effectiveness of the proposed method.

Key words: Web service, soundness, Petri net, service composition, service net
