摘要
本文从信息论观点出发,分析了环境评价中各评价指标(或因子)的模糊信息熵与权重之间的关系,认为可用模糊信息熵函数给各指标赋权。文中给出了实例,并利用模糊信息熵对评价结果的可靠性作了分析。
In this paper,the relationship between the weight w, and FUZZY information entropy H (xi)of each index x, in comprehensive evaluation is analysed from the viewpoint of information theory. Therefore,each index or, can be weighted with H(xi). Finally the entropy function H (xi) is introduced to the application of the environmental quality assessment, and the reliability of the assessment result is given by using the entropy H(B) of the FUZZY subset B.
