Study of Multi- attribute Evaluation Method Based on Rough Set Theory

The original fuzzy comprehensive evaluation use fuzzy math theory to describe the process of evaluation and some fuzzy factors,this evaluation model is feasible.but some problem consist in the model,for example,how to adjust the parameters of membership functions.How to design the structure of the model,how to select the fuzzy rules.In this paper,It designs a new model that combines rough set(RS) and fuzzy neural network(FNN).It is easy to design the structure of the model and pick up the fuzzy rules with Rosetta.It is a evaluation model that can used in many cases.
