摘要
根据最小机会损失准则提出了一种新的组合评价方法———最小机会损失组合评价方法。该方法运用最小机会损失原则处理各单一评价方法的结果值,用组合机会损失值到最小机会损失值距离最小的思想建立模型,计算出权重,从而把各单一评价方法以权重的形式组合起来,这样既克服了单一评价方法结果的非一致性问题,又尽可能减少了各方案失去其最高排序的风险损失机会。最后通过实例分析表明,该组合评价方法有效。
Based on the criteria for minimum loss of opportunity,this paper proposed a new combination evaluation method,combined evaluation of the minimum loss of opportunity.For the issue of determining weights,the result of each single evaluation method was dealt with by using the principle of minimum loss of opportunity.Based on the theory which was about the smallest gap between the combination＇s opportunity loss value and the minimum opportunity loss value,the model was built to derive the weights to compose the single evaluation method.Such method not only overcame the consistency problem of the results of a single evaluation method,but also reduced as far as possible the risking loss opportunity of the lost of its highest ranking of each scheme.Finally,an example shows that the combined evaluation method is effective.
