Abstract
How to select the service components and coordinate services composition have become key problems in dynamic web services. Based on the original discrete probability distribution, we propose a QoS model to support dynamic Web services composition, develop a WS_TSC algorithm for services composition QoS. We finally carry out a simulation experiment via this algorithm. Compared with San-Yih Hwang´s work, the experimental result shows that this model markedly reduces the response time and improves the rate of success and the rate of composition in dynamic Web services composition.
