| 摘 要： | 属性权重和属性值都是梯形模糊数的多属性决策问题是一种带有不确定性的决策,需要作不确定性分析后才能得出结论.为此把梯形模糊数表示的属性值和属性权重先用其特征函数"均值+偏差"联系数(特征联系数)表示,再利用联系数运算法则作"加权求和"运算,不仅获得与其它决策方法相同的结果,而且借助联系数中i的不同取值考察决策对象的排序变化,方法简便易行,且具有较强适用性.

| Abstract: | Weight properties and attribute value,both part of the multi-attribute decisionmaking of trapezoidal fuzzy number,are uncertain decision-marking,which require uncertainty analysis to gain the conclusion.Therefore,representing the weight properties and attribute value,expressed with trapezoidal fuzzy number,by the interval number of their characteristic function,then making the weighting summation provides the same conclusion with other decision-making methods in a more convenient and applicative way. |
