A Fuzzy Model for Selection of QoS-Aware Web Services

Abstract

With the increasing popularity of employing Web services, quality of service (QoS) measure of service becomes a significant concern for service consumers and providers. However, current technologies are poor to identify the relative importance of nonfunctional QoS criteria for Web services and they are not fitting well for selecting the appropriate service. In this paper, a new scheme for right selection of QoS-aware of Web services which exploits fuzzy logic to locate and select the right service based on customer's preference or satisfaction degree. The aim is to compute both functional and non-functional weightings of QoS criteria and to assist customers to make the right choice for Web services
