Expressway Project Operation Benefit Model Based on RoughSet-Neuro Fuzzy System

According to the characteristics of benefit evaluation of Expressway Project Operation,this paper puts forward a model of RoughSet-Neuro Fuzzy System evaluation,in which immune genetic algorithm is used to adjust the system parameters of controlled effectively to avoid the parameters of the transition training,making the system structure more streamlined and learning faster.Then we applied this model?to the example.The result of example verifies its validity and feasibility.
