%X For the purpose of solving the current problems in the role-based network model(RNM), this paper improved RNM from two aspects: time constrained, and the inheritance relationship between roles. And it realized the time constrained role-based network model (TRNM) based on the improved RNM. This model not only inherited all the advantages of RNM, but also provided time constrained and the proper inheritance relationship between roles. This paper specified the development methods about TRNM in the end.
