Four basic processes are analyzed in detail in network security decision,which are the base of NSDSS security decision. Then, developing strategies and methods are analyzed according to the objective and task of the system. Antetype method with RAD speciality is chosen to lead the developing process of the system. The structure of "Four-Base and Seven-System" of NSDSS is decided, based on which, the Function and Structure of Man-Machine Conversation system, General Management system, Data Base system, Model and Method Base system, knowledge base system, Causing and solving problems system are discussed. The basic theories and methods of each part are discussed. In the designing process of Model Base System, detailed analysis is given to the models of prediction, evaluation and management in the course of security decision. Moreover, basic process and method are discussed on question generation and solution. Then, detailed explanation is provided on the integration and implement of the system. After that, it is suggested that implement of the system should be carried through the process of the system.

One method is the arch-cantilever load-distribution method, in which the arch dam stress and abutment thrust are calculated, while the stability of abutment is evaluated by rigid body method or other method. The other is FEM method, which evaluates the arch dam stress and stability of abutment at the same time.
