Emergency Evacuation Route Planning of Cruise Ship Based on Intelligent Optimization Algorithm

When an emergency such as fire happens on a cruise ship, it is of great significance to quickly plan out a reasonable and effective emergency escape route to ensure the life safety of passengers. First, to achieve the safe evacuation of passengers in an emergency, a three-deck diagram is constructed as the simulation evacuation place, which is modeled by the combination of undirected graph and data set. Secondly, combined with the characteristics of passenger ship personnel composition, the comprehensive evaluation index of route is established, the planning principle of combining global static path planning with local dynamic path planning was formulated, and the path planning algorithm is realized by using Dijkstra algorithm and A* algorithm. Finally, taking an emergency such as fire as an example, considering the influence of the changes of situation information such as fire diffusion, passenger flow density and path cost on the result of path planning, the simulation experiment is carried out in a deck fire scene, and the evacuation situation under the conditions of delay time and fire location is analyzed and compared, It provides a reference for the formulation of reasonable emergency evacuation strategies and key prevention areas.
