Abstract
Current Web service selection methods mostly assume that all the QoS attribute values of Web services have to be the definite real numbers;but do not take into account the fuzziness property of QoS.This hypothesis has certain limitation in practical application requirement;what’s more,it will also cause the loss of a large amount of data information.To enhance the representation capability of QoS, we described the QoS attributes as the accurate numerical type,the interval numerical type and the fuzzy numerical type.At the same time, we used the order relations vector to represent the demand preference of user on different QoS attributes and converted them into user’s subjective weights on QoS attributes,as well as calculated the objective weights of QoS attributes with entropy weight.On this basis,we gave Web service selection process of hybrid QoS attributes by using relative superiority degree algorithm.At last we proved the effectiveness and rationality of the relative superiority degree algorithm through simulation and experiment verification.关键词
