This article discusses a previously published paper entitled “Factors influencing medical tourism adoption in Malaysia: A DEMATEL-Fuzzy TOPSIS approach” by Nilashi et al. (2019). In that work, the authors discussed the factors that affect medical tourism in Malaysia, using the DEMATEL method to explore the influence relationships among the factors and fuzzy TOPSIS to determine the importance ranking of the factors. However, there are some errors and incorrect fuzzy TOPSIS calculation formulas described in their paper. Furthermore, the applicability of the TOPSIS method to this problem is misguided. Although the authors provide interesting management implications and suggestions, the results of the analysis of the real case with fuzzy TOPSIS is incorrect.

本文讨论了Nilashi等人先前发表的题为“影响马来西亚医疗旅游采用的因素：DEMATEL-Fuzzy TOPSIS方法”的论文。（2019）。在这项工作中，作者讨论了影响马来西亚医疗旅游的因素，使用DEMATEL方法探索了因素之间的影响关系，并使用模糊TOPSIS确定了因素的重要性等级。但是，他们的论文中描述了一些错误和不正确的模糊TOPSIS计算公式。此外，TOPSIS方法在此问题上的适用性被误导了。尽管作者提供了有趣的管理含义和建议，但是使用模糊TOPSIS分析实际案例的结果是不正确的。
