| 摘 要： | 在考虑、分析多因素复杂问题时或自然界中都相当普遍地存在着各因素的权重因具体情况不同而变动的情况。为此提出一种各因素的权重由各因素的组合情况决定的模型——变权模型,以一种简单的基本形式,用实例说明根据若干已知样本建立变权模型的方法。其数学基础是回归分析。但又不同于多元同归分析。这对还不能达到数理化,又缺乏足够用于建模的可靠数据之地理学将会有较广的适用性。

| Abstract: | Varying weight problem is proposed for solving the problem, it has diverse weight when condition is diverse.This paper affords the basic form of varyingweighted models, weight of factor is bigger according as factor more restricting objective.where.membership-function of objectivepossibility-function of factor (xi)parameter electThis paper rel-ted method of building the varying-weighted model on simple condition. The last past of the paper discussed the difference of the varying-weighted model and model of multif actorial evaluation (A0R = B) |
