Web services composition is the latest software progress pattern and its main point to accomplish service-oriented computing presently. For gathering the QoS requirements of consumers, this paper presents QoS calculation rules and the formal standing to the services composition as the combinatorial optimization problem. In order to solve services composition, a new algorithm based on PSO algorithm is proposed, which is called Hybrid QPSO algorithm. The accuracy, viability, and usefulness of the algorithm are demonstrated using the experiments.
