Agent modeling for evacuation and amateur rescue under survivability-critical states in underground flooding

Vitae System based agent modeling has been proposed to simulate an evacuation and rescuing process under survivability-critical states. It has been shown that the Vitae System model can express individual abilities to keep one´s own life under survivability-critical states as characterized by three functions: survivability, vitality, and conviviality. Given an underground inundation case as an illustration, three functions, survivability, vitality, and conviviality, have specifically been defined to operationalize the conceptual model of the Vitae System. Vitality function (an evacuee´s stamina to remain in a substitute shelter) is redefined based on physiological studies. Self-evacuation and amateur rescue have been simulated and analyzed. Countermeasures for worst-case scenarios in underground flooding have been suggested. They include setting up substitute shelters near stairs, changing the shelter´s style to support the agent´s vitality, and partially mounting the stairs.
