| 摘 要： | 模糊综合评价方法是目前决策理论中使用极为广泛的一种方法:但模糊综合评价结果的可靠性和准确性依赖于合理选择因素和合理确定因素的权重等.特别对于有序分割类,模糊判别时通常使用的最小代价准则、最大属性测度准则以及最大隶属度准则由于掩盖了介于两个隶属度之间的差别,有时可能得出并不合理的结论.首先提出了一种利用拓广最小二乘算法综合指标权重的方法,然后基于置信度准则提出了一种改进的模糊综合评价方法.有效地避免了上述问题,而且编程实现极为方便简单.最后用一个实例说明了本文方法的有效性和可行性.

| Abstract: | Fuzzy comprehensive evaluation is one of the most widely used methods in the decision-theoretics,but its reliability and accuracy of fuzzy comprehensive evaluation results rely on the indexes chosen reasonably and weight vector determined reasonably. Especially for a sequential segmentation category,the principle of the lowest cost,the principle of maximum degree of measure and the principle of maximum degree of membership sometimes can get unreasonable conclusion,even sometimes can get error conclusion,bec... |
