基于联系数的多属性决策模型

Multiple attribute decision-making model based on connection number

针对权重为区间数且属性值为实数和区间数相混合的多属性决策问题,提出了基于联系数的多属性决策模型。该模型将区间型权重、实数型及区间型属性值转化成联系数的形式,利用联系数的运算规则确定决策方案的排序。该方法集确定与不确定分析为一体,反映了不确定性对结果的影响,所需计算量较少,便于应用。实例分析验证了该方法的有效性和实用性。

This paper investigates multiple attribute decision-making problems with weights of interval numbers to which the attribute values are given in the forms of real numbers and interval numbers. Based on connection number, a multiple attribute decision-making model is presented. Firstly, attribute weights and attribute values are expressed in the terms of connection numbers. Then ranking of decision is determined by operational principles of connection numbers. The proposed method combines the certainty and uncertainty analysis, involves less computation and allows an easier application. The stability analysis of ranking results shows the effect of uncertainty on the result. The paper gives an illustrative example to demonstrate the feasibility and practicability of the proposed method.
