一种基于案例的多准则排序方法

A case-based method for multi-criteria decision making problems

针对带有间接偏好信息的多准则决策问题,首先利用加性效用函数理论提出一种排序方法,该方法通过构建一个简单的优化模型,得到与间接偏好信息相容的各评价值的效用;然后,利用线性插值方法计算出剩下方案各评价值的效用,进而得到所有方案的综合效用及排序;最后,通过实例验证了该方法的有效性和可行性.

For the multi-criteria decision making problems with indirect preference information, a method for ranking is proposed by using the additive utility function theory. In this approach, a simple optimization model is constructed, and the utility of evaluation values are obtained, which are compatible with indirect preference information. The utility of remaining evaluation values are calculated by using linear interpolation idea. Furthermore, the overall utility and ranking of all alternatives are obtained. Finally, an example is given to illustrate the effectiveness and feasibility of the proposed method.
