Fault diagnosis for Web service composition based on Bayesian network
基于贝叶斯网络的Web服务组合故障诊断

A fault diagnosis model based on Bayesian network to identify the most likely problematic services in a Web service composition process was proposed. The Bayesian network topology construction method and the parameters configuration method were specified respectively in detail. A fault diagnosis algorithm based on the Bayesian network was proposed and the algorithm was analyzed. The experimental simulation show that the model can rule out the root cause of the problems in the Web service composition process effectively and efficiently.
