Fire safety plays a vital role in tourism management, which can cause significant loss of life and property. It is necessary to present an efficient fire safety evaluation for scenic spots. However, some key issues are not well addressed in existing methods. For example, how to model experts’ opinions and how to combine them are still open problems. To address these issues, a new evaluation method based on the Dempster–Shafer evidence theory and best-worst method is presented. First, a fire safety evaluation index system is constructed using the domino model. Domain experts can evaluate different factors with linguistic assessments. The best-worst method is used to determine the weights of different factors. Then, these weighted linguistic assessments are efficiently fused by Dempster’s combination rule to obtain the evaluation result. Finally, a case study is illustrated to demonstrate the efficiency of the proposed method in fire safety evaluation for scenic spots. The main contribution of the proposed method is to represent and handle the uncertainty in experts’ linguistic assessments, so as to decrease the uncertainty and improve decision making. In addition, the weight determination method BWM is easier and more reliable than the existing method AHP.

风景名胜区消防安全评估：证据最差的方法

消防安全在旅游业管理中起着至关重要的作用，这可能会导致严重的生命和财产损失。有必要对景区进行有效的消防安全评估。但是，某些关键问题在现有方法中并未得到很好的解决。例如，如何为专家的意见建模以及如何将其合并仍然是未解决的问题。为了解决这些问题，提出了一种基于Dempster-Shafer证据理论和最佳最差方法的评估方法。首先，使用多米诺模型构建了消防安全评价指标体系。领域专家可以使用语言评估来评估不同的因素。最坏的方法用于确定不同因素的权重。然后，将这些加权的语言评估与Dempster的合并规则进行有效融合，以获得评估结果。最后，实例研究表明了该方法在风景名胜区消防安全评价中的有效性。所提出的方法的主要贡献是代表并处理了专家语言评估中的不确定性，从而减少了不确定性并改善了决策。此外，权重确定方法BWM比现有方法AHP更容易且更可靠。
