环境质量灰色评价模型及其应用

根据灰色关联分析的地质，构造目标函数，运用拉格朗日乘数法求极值，建立了一种新的环境质量评价模型．结合实例说明了该模型的具体应用．与其它方法进行了对比，结果完全一致．该模型数学推导严谨、科学合理、分辩率高、可靠性强．

A GREY EVALUATION MODEL OF ENVIRONMENT QUALITY AND ITS APPLICATION

On the basis of the properties of grey relational analysis, a new evaluation model of environment quality is established by seeking optimum of objective function with the method of Lagrange's multiplier and its application is introduced combined with practice and the results achieved are coincident with that of other methods. The practice shown that the model is strict mathematically, rational, distinguishable and reliable in results.
