Research on combination evaluation method based on criteria of minimum loss of opportunity
基于最小机会损失准则的组合评价方法研究*

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.
