Priority method for a kind of multi-attribute decision-making problems

研究了属性权重信息完全未知且属性值以区间数形式给出的不确定型多属性决策问题 ,给出了区间数决策矩阵的规范化公式 .基于区间数相离度 ,给出了求解属性权重的一个简洁公式 ,并提出了一种基于可能度的决策方案排序方法 .最后通过实例说明了该法的实用性和有效性 .

This paper studies a kind of uncertain multi attribute decision making problems,in which the information about the attribute weights is unknown completely and the attribute values are in the forms of interval numbers.Some formulas for normalizing the decision matrix with interval numbers are given.Furthermore,a simple formula of maximizing deviations,based on deviation degree,for obtaining the attribute weights is given,and a priority method,based on possibility degree,for the uncertain multi attribute decision making problem is also proposed.Finally,a numerical example is given to show the feasibility and effectiveness of the method.
