Abstract
With the increasingly emerging Web services, QoS-aware service selection is an active research area on Web services composition. It is a complex combinatorial optimization problem, which solves how to find a best composition plan that maximizes user's QoS requirement. In this paper a QoS-aware Web services selection model is proposed using AND/OR Graph after discussing the QoS critera. The model is not only capable of dealing with sequence relations and fork relations, but also capable of dealing with parallel relations between services, and the multi-objective constraint function is defined to meet the QoS. Furthermore, a novel service selection algorithm is proposed based on the ant colony optimization. Finally, the algorithm is tested for the performance. © 2011 Springer-Verlag.
