Abstract: To realize the intelligent selection and combination in cloud manufacturing service, the matching process of cloud manufacturing requirement and cloud manufacturing service and the features of cloud manufacturing were elaborated. A formalization description of cloud manufacturing service and its composition template was presented from aspects such as classification, service ability, service load conditions, service interface standard and service quality. The Quality of Service (QoS) acquisition method of cloud manufacturing based on mutual evaluation mechanism was built, and the trust evaluation model for cloud manufacturing service was established. Based on service matching degree and global trust degree, the comprehensive optimization model was built and solved by genetic algorithm. The feasibility of the proposed method was verified by a numerical example and Matlab simulation.
