Abstract:In order to reduce the data evaluation of subjective factors and uncertainty in web services,the provider of web service with QoS uncertainty and ensure accuracy of the weight,a web service dynamic evaluation model was proposed.The gray processing method of GST(Grey System Theory)was used to solve user′s subjective scoring fuzzy data.and then the subjective weight of web services were used to calculate by AHP,the objective weight of web services were calculated by an improved entropy weighting method,the model also had a feedback mechanism,the provider of web service with QoS was revised by the monitoring center of QoS.Finally,the simulation results showed that the model could not only adapt to the dynamic changes in the environment,but also to ensure the QoS of user select services,the model that endured the individual differences in the evaluation,and malicious evaluation,experimental results showed that the service evaluation model and selection strategy were feasible and practical.
