研究了偏好值以不确定语言变量形式给出的多属性决策问题.介绍了不确定语言变量的运算法则,给出了不确定语言变量之间两两比较的可能度公式,提出了2种新的数据信息集成算子拓展的不确定语言集成(EULA)算子和区间语言集成(ILA)算子,并且分别提出了基于EULA算子和基于ILA算子的不确定语言环境下的多属性决策方法.这2种方法不仅简洁、易懂,而且在运算过程中不会丢失任何决策信息.最后,通过算例对2种方法的实用性和有效性进行了说明.
This paper studies the problem of multi-attribute decision-making with uncertain linguistic variables, introduces the algorithm of uncertain linguistic variables, gives the possibility formulas of any pairwise comparison between uncertain linguistic variables, (EULA) operator and Interlanguage Language Integration (ILA) operator which are extended by data information integration operator, and propose multi-attribute decision-making based on EULA operator and ILA operator based on uncertain linguistic environment Method.These two methods are not only concise and easy to understand, but also do not lose any decision-making information in the process of calculation.Finally, the practicality and effectiveness of the two methods are illustrated by examples.
