【摘要】：在评价中经常会出现评价者对某些关键评价指标有特定要求或评价结果的预期,数学分析表明由这些要求或预期提出的约束蕴含着该指标的临界权重,且可以通过最优化方法求解临界权重并据此进行约束式赋权.在评价具体对象时,评价指标得分的分布情况会影响评价结果,由此提出根据全部评价指标的标准偏差和最低得分指标的离差对权重进行调整的方法.
[Abstract]:In evaluation, there are often expectations that the evaluator has specific requirements or evaluation results for certain key evaluation indicators, and mathematical analysis shows that the constraints proposed by these requirements or expectations contain the critical weight of the index. And the critical weight can be solved by optimization method and the constraint weight can be obtained accordingly. When evaluating specific objects, the distribution of evaluation index scores will affect the evaluation results. Therefore, a method is proposed to adjust the weights according to the standard deviation of all the evaluation indexes and the deviation of the lowest score indicators.
