Evacuation Dynamics Analysis of Multi-agent Game in Nuclear Accident Field
Nuclear accidents are dangerous and easy to cause panic among the masses,and pose a serious threat to social order and public safety.Emergency evacuation is of great significance to reduce casualties and the interaction and game between individuals in the e-vacuation process are also important mechanisms of group dynamic evolution.This study aims to simulate the complex interaction behaviors among conflicting pedestrians during e-vacuation in a nuclear accident site.By combining spatial game theory with cellular au-tomata model,the evacuation dynamics based on agent game is established.Evacuees with two types of behaviors,namely selection behavior and imitation behavior,are considered in the evacuation model.The evacuees considered three game strategies:Patient,Normal,and Inpatient,with P being more cooperative,I more competitive,and N somewhere in between.Through numerical simulation,the results show that:evacuees are more inclined to compete in emergency situations;friction cost and individual behavior will also affect the choice of evacuation strategy.
