| Abstract: | The principle and method of preferential order evaluation was described. The model of the fuzzy preferential order evaluation was set up based on the second-level fuzzy evaluation theory, which could be used to evaluate environmental quality. As the uncertainty of random and fuzzy imformation could be described by using the fuzzy entropy, the uncertainty of this model was evaluated by using the fuzzy entropy, and a new model of fuzzy entropy function was set up. The application of entropy function was illustrated through actual examples. |
