优劣方案及规格化公式的选取是模糊优选多目标决策模型中的关键问题,直接影响到分析评价的结果. 在归纳总结各种规格化公式计算方法的基础上,建立了目标特征值及权重离散程度评价指标值,并结合算例对常用的优劣方案及规格化公式进行了对比分析. 研究结果显示,相对优劣方案与绝对优劣方案的评价结果排序一致,但前者评价值分散性更大. 当方案指标特征值相差较大时,两组优劣方案均可选取;当方案指标特征值相差较小时,应采用绝对优劣方案的评价结果值,但可同时参考相对优劣方案的评价结果排序. 对于规格化公式,在不同的优劣方案下,可根据离散程度量化指标值的近似标准适当选取. |
英文摘要: |
The choice of normalization formulae and the ideal and non-ideal plans is a key topic in the fuzzy optimization methodology which affects the evaluation results obviously. Dispersal indexes of characteristic values and weights are established as the approximate choice criterions based on the analysis of previous methods. Normalization formulae and the ideal and non-ideal plans are analyzed and applied to real cases. The results show that the evaluation results of relative ideal and non-ideal plans are more dispersed than those of absolute plans whereas their evaluation orders are consistent. While the alternatives characteristic values are dispersed obviously, the two plans are both feasible. When alternatives characteristic values are contiguous, the absolute plans are more appropriate than the relative ones, but the relative ones can be used for a reference. The normalization formulae can be recognized according to the values of dispersal indexes under different plans. |
