一种不确定型多属性决策的组合方法

A Combined Method of Uncertain Multi-attribute Decision-making

针对不确定型条件下的多属性决策问题,给出了区间数的规范化公式,消除了属性值之间量纲的差异,建立了基于区间数的不确定型属性权重的组合优化模型,提出了一种基于各属性客观权重的可能度方法,为不确定型的多属性决策提供了一种简单实用的可靠方法。最后通过一个算例说明了该方法的实用性和有效性。

This paper gives two formulas for normalizing the decision matrix in multi-attribute decision-making problems, which are used to deal with the interval numbers. It establishes the optimization model dealing with the weights of index. And it gives a method of possibility degree for deciding objective weights, which provides a simple and practical method for multi-attribute decision-making. At the ,same time the paper analyses its advantages as a widely used method compared with other methods. Finally, a numerical example is given to show the feasibility and effectiveness of the method.
