Abstract: To solve the matching problem of suppliers and demanders in cloud manufacturing environment,a two-sided matching model of cloud service was proposed based on Quality of Service (QoS).The linguistic assessment information given by service suppliers and demanders was transformed into numerical value by cloud model.According to multi-criteria assessment information,the satisfaction was calculated by variable fuzzy recognition method.By taking both sides satisfactions of QoS for service providers and demands as the optimization goal,a multi-objective optimization mathematical model was established,and the multi-objective function was converted into single objective function with weighted-sum approach.Simulation results showed that the proposed model could accurately select the most suitable cloud service for both sides.
