This study aims to propose a framework for designing appropriate triangular fuzzy numbers in a fuzzy analytic hierarchy process (FAHP) for selecting a road freight transport route and investigate the appropriate fuzzy numbers determined from a reliable consensus among participating experts based on the Delphi method.,The fundamental nine-point scale was investigated and separated into nonfuzzy intervals for importance assessment. A total of 17 individual experts participated in this study, and their consensus was that appropriate fuzzy numbers could be obtained using a three-round Delphi process. Moreover, the appropriate fuzzy numbers were used instead of the primary fuzzy numbers to calculate the relative weights of the decision criteria for road freight route selection.,The results confirmed that the Delphi method can be easily and rigorously applied to define appropriate fuzzy numbers. Further, this framework can serve as a guideline for a situation wherein the input of other fuzzy multiple criteria decision-making tools must be provided.,The FAHP has been widely used to address the imprecise assessments of decision-makers. However, most existing studies on the incorporation of such techniques have not defined fuzzy numbers, which are relevant to the problem of interest. This study contributes by incorporating the Delphi method that can design an appropriate fuzzy number for road freight route selection.

具有新模糊数的道路货运路线选择决策支持系统

本研究旨在为在选择道路货运路线的模糊层次分析法（FAHP）中设计适当的三角模糊数提供一个框架，并研究基于Delphi方法从参与专家之间的可靠共识中确定的适当模糊数。调查了基本的9分制量表，并将其分为非模糊区间进行重要性评估。共有17位专家参加了这项研究，他们的共识是，可以使用三轮Delphi过程获得适当的模糊数。此外，使用适当的模糊数代替主要模糊数来计算公路货运路线选择决策标准的相对权重。结果证实，德尔菲方法可以轻松，严格地应用于定义适当的模糊数。此外，该框架可以作为必须提供其他模糊多准则决策工具输入的情况的指导。FAHP已被广泛用于解决决策者的不精确评估。但是，有关这种技术并入的大多数现有研究都没有定义模糊数，模糊数与关注的问题有关。这项研究通过结合Delphi方法做出了贡献，该方法可以为公路货运路线选择设计适当的模糊数。FAHP已被广泛用于解决决策者的不精确评估。但是，有关这种技术并入的大多数现有研究都没有定义模糊数，模糊数与关注的问题有关。这项研究通过结合Delphi方法做出了贡献，该方法可以为公路货运路线选择设计适当的模糊数。FAHP已被广泛用于解决决策者的不精确评估。但是，有关这种技术并入的大多数现有研究都没有定义模糊数，模糊数与关注的问题有关。这项研究通过结合Delphi方法做出了贡献，该方法可以为公路货运路线选择设计适当的模糊数。
