摘要
介绍了优序评价的原理和方法.利用多级模糊评价理论建立的优序评价模型是评价环境质量优劣的一种方法.根据模糊熵可以描述随机、模糊信息的不确定性等特点,利用模糊熵对其进行评价,建立了模糊熵的熵函数模型,并结合实例说明熵函数模型的应用.
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.
