Abstract :
Web services composition is a new software development paradigm, and it is a key point to achieve service-oriented computing currently. For meeting the QoS requirements of consumers, this paper presents the QoS calculation rules and formalizes the services composition as the combinatorial optimization problem. In order to solve services composition, a new algorithm based on QPSO algorithm is proposed, which is called Hybrid QPSO algorithm and the correctness, feasibility, and effectiveness of the algorithm are demonstrated using the experiments.
