Abstract: To realize the service matching in cloud manufacturing platform,the selection criteria of cloud manufacturing service provider in cloud manufacturing system was proposed,and the general evaluation index system with the scalable quantification model were established.The project collaboration method was proposed to correct the index value.The service quality comprehensive performance ranking was obtained based on similarity between service providers and demand expectation calculated by triangular fuzzy number algorithm according to project collaboration.Combined with an example,the index system,data acquisition methods and models were verified.The results showed that the proposed evaluation index,attribute value calculation method and evaluation model were practical and could help the platform to accurately choose the best service.
