Abstract: In the cloud manufacturing environment,there are many types of cloud resources and service constraints,which make the cloud manufacturing service quality evaluation difficult.Aiming at the uncertainty of evaluation information and the variety of evaluation indicators,the service quality evaluation approach based on intuitionistic fuzzy cosine similarity was proposed.The non-quantitative service quality was evaluated by intuitionistic fuzzy number,which could express the membership degree and the non-membership degree.The similarity between the cloud manufacturing service attribute value and the ideal value was calculated by the cosine similarity which was not constrained by index type and dimension number.The weighted average of the quantifiable and non-quantizable service quality attribute similarities was used to obtain the comprehensive similarity,and the cloud manufacturing services were sorted according to the similarity.The effectiveness of the proposed approach was verified by the turbine production of a machine tool manufacturer.
