In the situation, this paper brought up the risk analysis and evaluation method on the basis of intelligent control and network communication technology for Network Communication System. The risk analysis and evaluation of Network Communication System firstly discussed the character of network communication and its risk. At the following we estimate a risk evaluation model according the distribution of the systems risk by time and space. Otherwise, we combined Fuzzy Comprehensive Evaluation with Analytic Hierarchy Process, and set up the multi-grade fuzzy comprehensive evaluation model for Network Communication System.
