A dynamic evaluation model base on expected object for comprehensive trust of supplier—STEM

Supplier is critical for enterprise. In order to solve the problems related to trust of suppliers, we, in this paper, propose a dynamic evaluation model base on expected object for comprehensive trust of supplier called STEM. Base on the expected object of enterprise, the concept of trust vector was introduced into STEM. Many kinds of factor that affect supplier´s trust and trust management that is used in network security were taken to this model. After that, a dynamic method was provided to evaluate comprehensive trust of supplier. Finally, the results of simulation experiment indicate that this model is feasible and effective.
