QoS-aware web service selection with global optimization refers to choosing appropriate component services to build global optimal composite services. In this paper, the authors propose a global optimization algorithm for QoS-aware web service selection based on the multi-objective genetic algorithm. The proposed algorithm can optimize multiple objectives simultaneously on the premise of satisfying multiple constraints and finally obtain a set of constrained Pareto optimum composite service solutions. Compared with single-objective optimization based on linear weighting method, the proposed algorithm provides more applicable solutions in which decision makers can make choices according to specific application requirements and their preferences.
