摘要
由于Web服务组合复杂多样,传统的Web服务组合可靠性测试分析系统无法对其进行有效测试,测试分析的准确性较低。因此,提出基于Petri网的Web服务组合可靠性测试分析系统,Petri网能够构建高质量且可靠的Web服务组合分析系统,所构建的系统中各个模块能够同步运转且独立进行工作,细致描述了Petri网Web服务组合中的原子操作模块、顺序操作模块、选择操作模块和共同操作模块的工作流程,并给出Web服务的可靠性分析函数表达式,以及Web服务本体扩展流程的关键代码。实验结果表明,所设计的系统是有效的,并且具有较高的可靠性测试准确性。
Since the traditional reliability testing and analysis system for Web service composition can＇t test it effectively due to the complexity of the Web service composition,and its testing and analysis accuracy is low,the Web service composition reliability testing and analysis system based on Petri net is proposed. Petri net can build high quality and reliable Web service composition analysis system,howse each module can run synchronously and work independently. The working process of atom operating module,sequential operating module,selection operationg module and mutual operating module in the Petri net Web service combination is described in detail. The function expression for reliability analysis of Web service,and the key code of the extension process for the Web service ontology are given in this paper. The experimental results show that the designed system is valid,and has high reliability and testing accuracy.
