Abstract:

In order to alleviate the problem of long evacuation time and low efficiency of building fire, based on the theory of Time-Colored Petri Net, modeling and performance analysis for the structural characteristics of a building was carried out. Through the calculation and analysis of the algorithm, the selection of different evacuation channels for different types of people was planned reasonably, and the time simulation of the model was carried out to improve the evacuation efficiency of people in the building. This paper proposes a management evacuation method with building fire evacuation factors, adds relevant color sets and time stamps, integrates algorithm calculation into the original model, simulates the fire evacuation time, and puts forward evacuation guidance schemes for different categories of people. The evacuation time is shorter, the efficiency is higher and the casualty rate is lower. The experimental results showed that compared with other models, the Time-Colored Petri Net model incorporating the management evacuation algorithm reduces the average evacuation time by 6.9 s, and the simulation results of this model have higher evacuation efficiency.
