The mastery of strategies of forests fire-fighting passes compulsorily by deep knowledge of forest fire phenomenon. One of the efficient means of apprehension of the forest fire, is to dispose of a tool that is capable to inform us about the behavior of fire before its apparition according to the given climatic conditions. In this context, the simulation remains an effective tool for the prediction of the fire behavior. It permits to determine with a relative confidence degree, susceptible zones to be ravaged by the fire during a determined period. The objective of this work is the study of mechanisms of forest fire progression by the elaboration of an automatic tool capable to pattern suitably a fire forest, its parameters, its propagation and its behavior in a given region. Throughout this study, it will make conspicuous the considerable property (perhaps unavoidable) the Geographical information Systems (GIS), in combination with techniques of simulation in the apprehension of a problematical " fires forest " [DAG 94]. This resides in the power of the GIS to modeling all phenomenon presenting a geographical character. The interest that presents such a survey for operators in charge of the management of a forest fire (Fireman department, services of forests, local collectivities, etc.) is double. It permits to define to the long term a homogeneous and coherent politics of forest fire prevention, whereas the system permits to verify the adequacy of amenities and presents infrastructures of wrestling against the fire with the reality of a disaster [DAG 97]. It also allows to determine, in the perspective of the beginning of a fire, means to put in work for a coordination of intervention teams and a strategy that remains efficient, of wrestling against the fire progression
