摘要
针对动态系统的多指标多决策者综合评价问题,目前的赋权法很少考虑决策者评价可信度及指标权重随评价对象变化而变化的情况,因此提出一种基于置信度的参数可调的S型曲线指标赋权模型。在专家打分法的基础上,通过引入专家权威性和差异性系数来确定专家置信度,提高专家评价的可信度,运用可调参数来校准基于置信度的指标赋权模型,使其能较好地解决评价者与动态系统中指标权重之间的非线性关系,增加了赋权模型的灵活性。结合实例确定指标权重的结果符合客观实际,验证了此方法的可行性和实用性,它为确定指标权重提供了一种新的有效途径。
Aiming at the problem of comprehensive evaluation of multiple decision makers and multi index for dynamic system, the current weighting methods seldom consider the credibility of the decision-makers and the change of target weight with the variation of the evaluation object. A parameter weighting model based on confidence adjustable type S curve index was proposed. Based on the expert scoring method, through introducing expert authority and difference co- efficient of experts to determine expert confidence, it enhances the credibility of expert evaluation. An adjustable para- meter is used to calibrate the weighting model based on the confidence index, which can solve the non-linear relation be- tween the evaluation index weight and the dynamic system and increase the flexibility of the weighting model. Combi- ning the results to determine the index weight in accord with the objective reality, it verified the feasibility and practica- bility of this method, provided a new method for determining the index weight.
