Abstract
In the service-oriented environment, a single Web service can hardly satisfy the given request, so the composition of multiple Web services is required to fulfill the goal. Without considering the inherent stochastic and dynamic nature of Web service, the existing composition methods mostly generate static plans. As a result, Web service composition often terminates with failure inevitably. In this paper, metrical methods of several random QoS dimensions and QoS Management Architecture are presented, and one reliable Web service composition algorithm is also designed based on markov decision process (MDP)—only dynamic controlling method of stochastic discrete event system (SDES). Experimental results demonstrate the success rate of Web service composition has been improved greatly.
