Abstract

Evolution research regarding the impacts of lifeline systems on urban safety is necessary to
prevent major disasters. The causes and consequences of a disaster were classified based on various failures
of lifeline systems and then described for risk evaluation. We established four evolutionary models
representing personal injury and death, public transport inconvenience, daily life difficulties, and nationwide
panic. The various consequences of urban disasters occurring through correlated events were depicted in full
view. The proposed method can help decision makers efficiently establish proper measures to prevent
unexpected hazardous events to develop further.
