基于可靠度确定属性权重的三角模糊数多属性决策方法

The Multi-attribute Decision-making Method of Triangular Fuzzy Number with Attribute Weight Determination Based on Reliability

针对三角模糊数多属性决策中的属性权重确定问题,从属性维度和方案维度分别考量决策信息的相似度差异指标和不确定性指标,提出了一种基于可靠度确定属性权重的方法。并结合三角模糊数可能度比较关系理论给出了完整的决策步骤,最后通过实例应用和对比分析,验证了所提方法的有效性和可行性,为此类问题的科学决策拓展了思路。

In view of the attribute weight determination problem in the multi-attribute decision-making method of triangular fuzzy number, this paper proposes a method to determine the attribute weight based on reliability in which the similarity difference index and uncertainty index of decision information are considered from attribute dimension and project dimension respectively. Then the complete decision steps are given combined with the possibility degree comparison relation theory of triangular fuzzy number. Finally, the proposed method is illustrated effective and feasible through example application and the comparative analysis, which expands the idea for the scientific decision of this kind of problem.
