Agent-based modelling of the evacuation of endangered areas in crisis situations

Abstract

The evacuation process from endangered areas (EA) into safe spaces in crisis situations is modelled by means of simple agents (gate-ways equipped by sensors). Petri nets (PN) are utilized here to model the EA structure as well as the agents and their cooperation. More precisely, timed PN (TPN) and first-order hybrid PN (FOHPN) are used to do this. Rooms, other spaces to be evacuated (corridors) and the safe spaces out of EA (where people are evacuated) are modelled by TPN places and FOHPN continuous places. Gate-ways are modelled by TPN subnets and by FOHPN continuous transitions. While the supervisor for the TPN gate-ways can be synthesized by means of place/transition PN (P/T PN), the blocks of FOHPN discrete places and transitions are used to affect the gate-ways. Depending on the immediate throughput of the gate-ways the escape time behaviour is found in the process of simulation. This paper is the extended version of the paper (Čapkovič Intelligent Information and Database Systems. LNAI. Springer, Cham Heidelberg 2014) presented in the ACIIDS 2014 conference.

Research on Personnel Emergency Evacuation Model Based on Multi-agent

“…From the point of view of the current research, the macroscopic model in the simulation model considers the simulated object as a whole and ignores the differences among individuals. While the microscopic model considers the heterogeneity of groups, literature [1]proposes a universal Agent evacuation simulation _______________________________________ model, and literature [2][3][4][5][6][7][8]studies the application of multi-agent in large-scale public places such as gym, subway and mine evacuation. In this paper, through the establishment of a micro-simulation model of the disaster area, the study of various characteristics of emergency personnel, the introduction of multi-agent technology, the evacuation process of personnel in various circumstances simulation, the results show that increasing the number of exits and the width of the exit, the evacuation process with the guide can effectively improve the efficiency of evacuation.…”
