动态三角模糊多属性决策的VIKOR扩展方法

针对各决策时段的时间权重,以及属性权重已知、属性值以三角模糊数形式给出的动态多属性决策问题,提出了一种基于多准则妥协解排序拓展的决策分析方法。该方法依据传统多准则妥协解排序法的基本思想,结合三角模糊数的运算法则,计算各时段各方案的评价值。利用给出的动态三角模糊加权平均算子对各时段的评价值进行集成,以获取各方案的综合评价值。利用三角模糊数两两比较的可能度公式对其进行比较,进而得到整个方案集的排序。通过实例分析表明了该方法的实用性和可行性。

Human Immunodeficiency Virus (HIV) infection model based on triangular neutrosophic cubic hesitant fuzzy number

In this paper,we define the basic concept of triangular neutrosophic cubic hesitant fuzzy number and their properties.We develop a triangular neutrosophic cubic hesitant fuzzy ordered weighted arithmetic averaging (TNCIIFOWAA) operator and a triangular neu-trosophic cubic hesitant fuzzy ordered weighted geometric averaging (TNCIIFOWGA) operator to aggregate triangular neutrosophic cubic hesitant fuzzy number (TNCHFN) information and investigate their properties.Furthermore,a multiple attribute decision-making method based on the TNCHFOWAA operator and triangular neutrosophic cubic hesitant fuzzy ordered weighted geometric (TNCHFOWG) operator and the score function of TNCHFN is established under a TNCHFN environment.Finally,an illustrative example of investment alternatives is given to demonstrate the application and effec-tiveness of the developed approach.
