摘要：With the rapidly increasing number of Web services, the consumers have to choose suitable service from a wealth of web services according to the comprehensive factors. QoS is an important criteria to assess whether the consumer’s requirements are met by web service. But the QoS attributes offered by many web service suppliers are uncertain, especially the non-functional QoS attributes. In this paper, in view of the uncertain QoS attributes in the process of selecting web services, presents the method of selecting web service on basis of QFD-IFS (Quality Function Deployment- Intuitionistic Fuzzy Sets). Describe the consumer’s requirements and QoS attributes with intuitionistic fuzzy sets. Construct the QFD model transforming requirements of consumer into QoS attributes, which gives comprehensive consideration to the relations between requirements of consumer and QoS attributes, and to the impact of the correlation between the QoS attributes on the weights of QoS attributes. After the modified intuitionistic fuzzy entropy is used to obtain the entropy weights of the QoS attributes and alternatives. In the end an example show that the proposed method is feasible and effective.
