基于绑定图的Web服务可靠性预测模型
Reliability Prediction Model for Web Service Based on Binding Graph
摘要
Abstract
In order to improve the prediction accuracy of reliability for composite services,this paper proposes a new dynamic prediction model for Web service reliability. A composite service is divided into executing path, service composite module and atomic service according to composite grain. Binding graphs for composite unites are built,and the reliability models for the composition unites are presented based on these binding graphs. The reliability models are integrated for composite services. Example analysis result show that,compared with the traditional reliability prediction model,the proposed model only computes the updated reliability,reduces the computation complexity,and a more flexible sensitivity analysis is performed to determine which service component has the most significant impact on the improvement of composite service reliability.关键词
