摘要
多指标权系数赋值是多指标决策的重要环节 ,它在相当程度上决定了决策过程的精确性。简要分析了当前指标赋权法的优缺点 ,给出了一种利用基点和熵计算指标权系数的方法。该方法以优化理论和 Jaynes的最大熵原理为依据 ,以待评方案距基点的加权距离和权系数信息熵为优化目标 ,建立了新的数学模型 ,并给出了精确解 。
Multiple index wight, an important part in multiple index decision making, determines the precision of multiple index decision. After analyzing the shortcoming of existing methods on determining the index weight, a method is presented based on base points and entropy. By using optimization theory and Jaynes' maximum entropy principle, a new mathematics model which optimizes the distance of project being evaluated and base points and weights' entropy is established. The exact solution has been obtained and an example demonstrates the validity of this method.
