This study aims to select the most suitable truck-mixer drum (TMD) for construction firms and to present a scenario-based approach to the construction equipment selection problem through the fuzzy data envelopment analysis (FDEA). The technical data of TMDs for quantitative criteria were initially obtained from three TMD companies operating in Turkey. A semi-structured questionnaire survey was then applied to 90 users (i.e., ready-mixed concrete companies) of these TMD brands for qualitative criteria. A scenario analysis, including four different scenarios, was lastly carried out by using FDEA. Considering each scenario, the best alternative was identified for TMD buyers. This study may be beneficial for researchers who can investigate (i) the decision-making process in the domain of the construction equipment selection and (ii) selection criteria of TMDs. This study may also help both potential buyers to make proper equipment selection decisions and TMD manufacturers to improve their products and competitiveness. In terms of originality, the study is first to focus on the selection process and criteria of TMDs. Similarly, FDEA was utilized for the first time in a construction equipment selection problem. As a limitation, the number of respondents, criteria, and alternatives might be increased to reveal more robust solutions.

这项研究的目的是为建筑公司选择最合适的卡车搅拌桶（TMD），并通过模糊数据包络分析（FDEA）提出一种基于场景的解决建筑设备选择问题的方法。用于定量标准的TMD的技术数据最初是从土耳其的三家TMD公司获得的。然后，针对这些TMD品牌的90个用户（即，预拌混凝土公司）进行了半结构式问卷调查，以定性为标准。最后，使用FDEA进行了包括四个不同方案的方案分析。考虑每种情况，为TMD购买者确定了最佳选择。这项研究对研究（i）建筑设备选择领域的决策过程和（ii）TMD选择标准的研究人员可能是有益的。这项研究还可以帮助潜在的购买者做出适当的设备选择决策，也可以帮助TMD制造商改善其产品和竞争力。在独创性方面，该研究首先关注于TMD的选择过程和标准。同样，FDEA首次用于建筑设备选择问题。局限性是，可能会增加受访者，标准和替代方案的数量，以显示更可靠的解决方案。在独创性方面，该研究首先关注于TMD的选择过程和标准。同样，FDEA首次用于建筑设备选择问题。局限性是，可能会增加受访者，标准和替代方案的数量，以显示更可靠的解决方案。在独创性方面，该研究首先关注于TMD的选择过程和标准。同样，FDEA首次用于建筑设备选择问题。局限性是，可能会增加受访者，标准和替代方案的数量，以显示更可靠的解决方案。
