三角直觉模糊数(TIFNs)是真实的数集上的一种特殊的直觉模糊集(IFS),对于决策者刻画其模糊偏好信息非常有用。在这项工作中,我们研究了多属性群决策(MAGDM)问题,其中的选项的评级表示与TIFNs,属性和DM的权重是完全未知的。首先定义了TIFNs的清晰加权可能性均值,并基于Hausdorff距离定义了TIFNs的汉明距离和欧氏距离。提出了三角直觉模糊加权平均算子。然后,应用Shannon熵测度计算属性权重,结合证据理论和贝叶斯近似客观地确定DM的权重。通过使用TIF-WA算子将所有DM的个体决策矩阵聚合成组决策矩阵。因此,经典的Vlsekriterijumska Optimizacija I Kompromisno Resenje(VIKOR)方法扩展为求解具有TIFNs的MAGDM。最后根据方案相对于理想解的接近程度给出方案的排序。人员选拔实例验证了该方法的有效性。
Triangular intuitionistic fuzzy numbers (TIFNs) are a special intuitionistic fuzzy set (IFS) on a real number set, which are very useful for decision makers (DMs) to depict their fuzzy preference information. In this work, we investigate multiple attribute group decision-making (MAGDM) problems in which the ratings of alternatives are expressed with TIFNs, and the weights of the attributes and DMs are completely unknown. Firstly, the crisp weighted possibility mean of TIFNs is defined, and the Hamming distance and Euclidean distance for TIFNs are defined based on Hausdorff distance. The triangular intuitionistic fuzzy weighted average (TIF-WA) operator is developed. Then, the weights of attributes are calculated by applying Shannon entropy measure and the weights of DMs are determined objectively combining the evidence theory with Bayes approximation. The individual decision matrixes for all DMs are aggregated into the group decision matrix by using the TIF-WA operator. Thereby, the classic Vlsekriterijumska Optimizacija I Kompromisno Resenje (VIKOR) method is extended for solving the MAGDM with TIFNs. Finally, the ranking order of alternative is given according to the closeness of alternative with respect to the ideal solution. The personnel selection example verifies the effectiveness of the proposed method.
