In order to investigate the influence of factors such as pheromones and avoidance behavior on evacuation heterogeneous crowds, a multi-speed cellular automata model based asymmetric competitiveness is proposed for complex groups in single-exit room. By optimizing crowd density pedestrian speed equations, crowds can be obtained model. achieve description multi-dimensional population, considered pedestrians with different speed, age, gender, etc., by considering character existing among pedestrians, also discussed this It well known that information received different. consider asymmetry information, are introduced into discuss effect differences evacuation. The results show has facilitating best when radius pheromone about 3 m. Moreover, time weakly correlated pedestrians’ gender but strongly age. plays positive role evacuation, reaches minimum value probability 0.5. slope reduction greatest threshold 0.4 0.8. findings support capacity assessment, emergency planning, decision making.

Current static evacuation path planning methods are unable to meet the demands of real-time changes in fire scenarios. Therefore, a bi-objective dynamic (BODP) method for paths is proposed not only minimize time but also reduce thermal radiation dose received by personnel during process. The BODP includes both an equivalent rule first based on linear weighting method, and improved Dijkstra algorithm designed this paper. Because them, can normalize same degree perform multi-sink hexagonal grid map, order find optimal with lowest cost event tank farm fire. This accounts changing scenarios avoids potentially high-risk paths. Finally, case study chemical plant conducted demonstrate effectiveness method. results indicate that better suited complex resolves issue found planning: first-degree burn probabilities derived from estimated doses 34% lower than those actual doses, resulting unnecessary casualties. Additionally, applicable involving domino effects triggered incidents. provides scientific reliable technical support emergency fires, greatly contributing safety protection personnel.

In this study, 1/1 scale Fire Experiment Laboratory was built to demonstrate the reality of fire with a real fire. prepared building, there are 2 test rooms measuring 300 × 350cm and 1 observation room 190 620cm. tests, living bedroom were furnished by calculating required loads. load calculation, index value 1.18 obtained in 1.86 room. Instant temperature values taken for each second lower, middle top zones rooms. The reached maximum temperatures around 1200 °C zone, 800 zone 400 lower zone. And room, measured at 900 600 Moreover, changes outside building also recorded. According thermal camera images measured, external wall is 25–31 41–46 temperature.
