To meet the needs of integrating military airports for both peacetime with wartime operations and to improve the cost-effectiveness of flight support IoT construction, research on the application of IoT technology in the field of flight support at military airports, and study methods for evaluating its effectiveness. This paper introduces the technical architecture and composition of IoT flight support at airports, focusing on analyzing the characteristics and selection principles of effectiveness evaluation methods, pointing out the challenges faced by effectiveness evaluation of IoT systems at military airports, and looking forward to the future development direction of effectiveness evaluation work. This overview can provide reference for researching the effectiveness evaluation of IoT systems in military scenarios.
