Determination Algorithm of Service Composition based on QoS Relation
In order to represent the relation between different service classes, service requesters preference as well as internal relations among different QoS factors in service composition. We propose Determination Algorithm of Service Composition based on QoS Relation. QoS properties such as price, availability, response time, reliability and reputation are defined and used in the algorithm. Furthermore, we make use of uncertain theory to construct co-QoS which aggregated by availability, reliability and reputation. As a result, in evaluating the quality of service composition, we take relations on QoS properties between different service classes into account to some extent. The result of experiments show the algorithm holds good executive efficiency, stability as well as outstanding outcome.
