Simulation of Optimized Evacuation Processes based on Sub-Goal CA Model

چکیده
With the full swing of computer technology, evacuation models are constructed and simulated via computers to study the various phenomena and behaviors during the evacuation process. They open unique potential opportunity to evaluate the architectural design and provide the decision support for the emergency evacuation plans. This paper details a capacity constrained route planner (CCRP) algorithm, which is used to optimize evacuation path, and the distance map based on sub-goal cellular automata (CA) is also proposed to simulate the evacuation scenarios. Two evacuation scenarios are further discussed, and the experimental results strongly suggested that the sub-goal CA model could simulate the evacuation scenarios and evaluate the emergency evacuation plans effectively and finally help us penetrate to the essence of reality.

Simulation of Optimized Evacuation Processes in Complex Buildings Using Cellular Automata Model
Emergent evacuation is particularly prominent in events of various disasters. However, most existing evacuation models are either missing some human behavioral characteristics in crowds, or are computationally complex. In the paper, a cellular automata (CA) model is proposed to verify validity of evacuation plan. In the model, route is defined by a series of sub-targets. A “distance map” concep...
متن کاملApplication of the multi-laminate sub-loading surface model in the simulation of a pipe-jacking operation
In this paper a constitutive model formulated in the framework of multi-laminate models is applied to analyze pipe-jacking processes. The multi-laminate -based models consider various integration planes to formulate the stress-strain relationship. This basic feature of the framework has the advantage that yield criteria, flow and hardening rules are formulated on planes rather than in three-dim...

Computer simulations have become an important tool for analysing egress processes and assessing evacuation concepts. Especially so called microscopic models can by now be considered state of the art. In this paper we will describe the software PedGo which is based on a 2D cellular automaton and its application to the simulation of evacuations form large and complex structures. The focus is on t...
متن کاملAssessment and Analysis of Evacuation Processes on Passenger Ships by Microscopic Simulation
The analysis of evacuation processes onboard passenger ships has attracted increasing interest over the last years. Cellular automaton models, widely used for traffic simulations, provide a natural approach towards pedestrian dynamics. Two major difficulties are intrinsical to the problem: two-dimensional movement of pedestrians and the complexity of psychological and social influences. An impr...
متن کاملSimulating pedestrians in evacuation processes: a novel approach
Pedestrian simulation is a central issue in evacuation related topics; an issue that has recently received renewed interest. In order to estimate escape time from a building, this paper describes a two-module model which combines Agent-Based Models (ABM) and Cellular Automata (CA). The former module (ABM) simulates pedestrians exploring the building space; the latter (CA) simulates the proper e...
