摘要

In order to filter out the Web service needed by requester from the set of Web service in abundance speedily, the paper proposed a sort of selection strategy in Web service based on the fusion of QoS and reliability. In the paper, aimed at the similar complexity of Web function it made the anatomy of existent limitation in the current selection mechanism, and by means of integrated estimation of service reliability and through the monitoring data of service quality in third side it evaluated the Web service selection from two aspects in subjectivity and objectivity factors. And based on the model of QoS monitoring, target consumption group and service quality estimation as well as feedback evaluation, it finally it constructed the model of Web service selection. It took three cases as example to make the simulation, and validated that the proposed strategy not only could adapt dynamic varying environment, but also could ensure the actual service quality, and overcame the individual difference of evaluation. The research results demonstrate that the proposed strategy of service selection is feasible and practicable.
