介绍了精确语言变量和不确定语言变量的距离测度,并且基于精确语言变量和不确定语言变量,给出了属性值的正语言理想解和负语言理想解的概念.为了对决策方案进行排序和择优,基于2种语言变量的距离测度和语言理想解,提出了一种不同类型语言信息下的多属性决策方法.该方法不仅易于对语言变量进行计算,而且在求解过程中不会丢失任何语言决策信息,从而保证了决策结果的合理性和有效性.最后,利用算例对方法的运算过程进行了具体分析和说明.
This paper introduces the distance measure of exact linguistic variables and uncertain linguistic variables, and gives the notion of positive linguistic ideal solution and negative linguistic ideal solution of attribute value based on exact linguistic variables and uncertain linguistic variables.In order to sort decision making schemes and Based on the distance measure and language ideal solution of two linguistic variables, a multi-attribute decision-making method under different types of linguistic information is proposed, which not only makes it easy to calculate linguistic variables but also can not lose any language in the process of solving Decision-making information, so as to ensure the rationality and effectiveness of the decision-making results.Finally, a calculation example is used to analyze and explain the operation of the method.
