Abstract: To solve the service trust evaluation problem in cloud manufacturing environment to provide selection criteria for service consumer and management methods for platform operators,a hierarchical and configurable trust evaluation model of service was proposed.The evaluation object was divided into three levels: service instances,service products and service owners.By considering the characteristics of different types of cloud manufacturing service,the trust evaluation criteria systems both for general evaluation metrics and for specific evaluation metrics were built reductively from bottom to top according to the relationships between successive levels of evaluation objects.With the proposed method,cloud manufacturing platform operators could customize trust evaluation models dynamically according to the levels,service types and resource types of different evaluation objects.
