In large indoor public spaces such as office buildings and shopping malls, the complex architectural layout and dense population increase the difficulty of emergency evacuation. In the event of a fire or other disaster, the lack of effective evacuation measures can lead to significant casualties and property loss. This paper studies fire evacuation maps in China based on the Analytic Hierarchy Process (AHP) and Fuzzy Comprehensive Evaluation (FCE) methods, aiming to improve the cognitive efficiency and user experience of evacuation maps. The study first constructs a hierarchical index system for evacuation maps, determines the weights of various design elements, and forms a judgment matrix through evaluations by experts and users. Then, the optimized evacuation map undergoes a comprehensive evaluation analysis. The results show that clarity and functionality are the two aspects users are most concerned about, with the recognizability of signage and the accuracy of location information being particularly important. The optimized evacuation map shows significant improvements in clarity and information transmission, effectively guiding people to quickly escape in emergencies. This study validates the rationality and feasibility of the AHP-FCE method in the design of fire evacuation maps, providing new ideas and directions for further optimization of evacuation maps.
