一种基于最大离差和熵的多指标评价方法

A Method of Multi-object Decision-making Based on Maximum Deviations and Entropy

给出了一种多指标评价的方法。该方法利用待评方案之间的综合评价值离差最大化原则和 Jaynes最大熵原理 ,建立了新的数学规划模型。利用拉格朗日乘子法给出了模型的唯一最优解 ,即评价指标的权系数。该方法便于根据实际情况 ,合理地确定各指标的权系数。

A new method of multi object decision making is presented.By using the maximum deviation of project′s evaluation value and Jaynes′ maximum entropy principle, a new mathematics programming model is established. The optimal solution is the best index weight coefficients, which is solved by Lagrangean multiplication technology, and also the exact and reliable evaluation results without subjectivity are obtained. Finally an example that demon strates the validity of this method is given.
