An interplay model for rumour spreading and emergency development

Rumours influence how people make decisions in an emergency-affected environment. Conversely, the development of situation is affected by public action as well. We present a model for describing the interplay between turnout spreading and emergency development. Then, we describe a formulation of this model and derive, from differential equations for some possibility of the positive role of rumours in the control Of Situation and social loss. Our results show that rumour spreading at certain rate has positive effects on Situation stability and especially has delaying effects oil the rapid proliferation of ail emergency. Finally, we outline a strategy for authorities that can contribute to turnout management in an emergency event. (C) 2009 Elsevier B.V. All rights reserved.
