Subjectivity is well-known to be one of the most significant issues encountered in evaluating geoheritage. Even if frequently used quantitative evaluation methods reduce this problem to some extent, it is impossible to eliminate subjectivity. Based on this problem, the present study aimed to integrate Bipolar Fuzzy Numbers (BFNs) into geoheritage assessment methods. The proposed methodological approach was applied as a case study on five geomorphosites detected in Artvin province in Türkiye. At this stage, six main and twenty-one sub-criteria obtained from the literature were compared with five alternatives and rated by five experts using linguistic variables. Then, the ratings of each expert were converted into BFNs and combined into a single matrix. This obtained matrix was transformed into the final matrix with the ranking function of BFNs. In the last stage, the criteria weights were determined with CRITIC, and the ranking values of the alternatives were determined according to the criteria with MABAC. According to the results, the most important geomorphosite was the Hatila Basalt Columns. The proposed methodological approach has proven to be a viable method of avoiding subjectivity in geoheritage assessment. In this sense, it is predicted to make significant theoretical contributions to the subject literature.

众所周知，主观性是评估地质遗产时遇到的最重要的问题之一。即使常用的定量评价方法在一定程度上减少了这个问题，但也不可能消除主观性。基于这个问题，本研究旨在将双极模糊数（BFN）集成到地质遗产评估方法中。所提出的方法被应用于对土耳其阿尔特温省发现的五个地貌岩的案例研究。在此阶段，将从文献中获得的六个主要标准和二十一个子标准与五个替代标准进行比较，并由五位专家使用语言变量进行评分。然后，每个专家的评分被转换为 BFN 并组合成一个矩阵。使用 BFN 的排序函数将获得的矩阵转化为最终矩阵。最后阶段利用CRITIC确定标准权重，利用MABAC根据标准确定备选方案的排名值。根据结果​​，最重要的地貌是哈蒂拉玄武岩柱。所提出的方法已被证明是避免地质遗产评估主观性的可行方法。从这个意义上说，预计它将对该学科文献做出重大的理论贡献。
