熵权多目标决策模型在水环境质量综合评价中的应用

Application of Multiobject Decision Model Based on Entropy Weight to Evaluate the Water Environmental Quality

介绍了熵和熵权的概念与性质,在此基础上结合多目标决策模型建立熵权多目标决策评价方法,并对水环境质量进行综合评价,评价结果与物元分析模型、属性识别理论方法、模糊隶属函数法进行对比,结果表明,利用熵权多目标决策评价法进行水环境质量综合评价是可行的。

The concepts and characters of entropy and entropy weight are introduced. The muhiobject decision model based on entropy weights is established by combining the entropy weight and muhiobject decision model. The model is used to evaluate the water environmental quality. The assessment results are compared to that from matter element model and the attribute identify model and the fuzzy administering function. Using the multiobject decision model based on entropy weight to evaluate the water environmental quality is feasible.
