  • The different results of composition conditions make different impact on the reliability of composite services, in this paper, to improve the prediction accuracy of reliability for composite services, we proposed a reliability prediction model for composite services combining control-structure (e.g. sequence, if/switch, while, repeatuntil, foreach and flow) and composition condition. With this method, we firstly discussed the reliability of composition conditions and the influence of different control structure on composite services. And We presented an Extended reliability block diagram (ERBD) to describe the reliability of composite services. In the ERBD, composition conditions are regarded as atomic services and the reliability of composite services are evaluated according to their structures. Then, we designed an experiment to support our reliability model. The experimental results show that our model can obtain better reliability prediction accuracy than traditional model.
