The crisis management is a special type of collaborative approach in which the actors are subject to an uninterrupted stress. It is quite a significant issue because the consequences of crises can bring huge damages (human and economic losses). Even actors follow training in order to face stress situations but the human condition (familial and life) and the disparity of situations in which the consequences (different types of victims (children, the elderly, etc.) push actors to lose control of situations. The question to answer is can we predict the consequence of a default to this type of situation? Our study try to answer these questions by showing how to represent prediction of the consequences of a stress on crisis management. Firstly, we define a model that represents the impact of one actor to the situation considering the collaborative aspect of crisis and then we study stress consequences measurement. First results of these studies are presented in this paper.
