摘要
可拓评价方法已经成为对事物、方案和策略进行评价的比较成功的系统评价方法.在多特征综合评价中,确定各特征的权重成为关键的环节.利用待评基元各特征的关联度,提出基于关联度离差的客观赋权法,介绍了主、客观权重集成方法.该方法利用关联度确定特征的权重,无需对数据进行预处理,改变了以往确定权重直接利用指标量值的做法;可以尽量拉开综合关联度之间的距离,避免数据处理的敏感性对评价的影响,使综合评价的结果更符合直观;确定的权重具有系统性的特点.
The extension evaluation method has been a more successful system one to evaluate the alternatives, schemes and strategies. For an integrated evaluation problem with several characteristics, it is a key to endow with weights. To utilize each dependent degree of the basic element＇s characters, this paper proposes the objective method to get weights based on their variance, and introduces the integrated approach to the subjective and objective ones. The weights by the methods are obtained through the dependent degree, and need not deal with the datum in advance. It is different from previous methods, by which weights are directly obtained from the values of characteristics. The method can enlarge the distance among integrated dependent degrees as possible as they can, and avoid the impact of sensitivity of datum. To utilize the proposed methods, the evaluated result is more intuitive and the weights are system ones.
