Abstract: With science and technology developments, unmanned aerial vehicle (UAV) applications in emergency rescue has attracted increasing attention. However, despite their significant advantages, UAVs encounter multiple obstacles in practical applications. Using a hybrid of the best-worst method (BWM) and decision testing and evaluation laboratory (DEMATEL) method (BWM-DEMATEL), this study systematically identifies and analyzes the key obstacles affecting UAV use in emergency rescue. First, through literature review and expert interviews, an obstacle factor system is established comprising six primary indicators: technical limitations, operation and training, law and regulations, environmental adaptability, cost and resources, social acceptance, and ethics. Then, BWM is used to screen the primary and secondary indicators, and a new indicator system is determined for the next step. Next, the causal relationship between the obstacles is analyzed using the DEMATEL method, which reveals the internal structure and interactions between obstacles. The results show that technical limitations, operation and training, law and regulations, and cost and resources are the four most important primary indicators. Essentially, these are the key factors hindering the wide application of UAVs in emergency rescue. Finally, some suggestions and strategies are proposed to provide theoretical support and practical guidance for more efficient UAV applications in emergency rescue.
