Considering wildl<strong>and</strong> fire phenomena, defining a conceptual model consists in gradually specifying a<br />
particular domain of interest. Here, starting from a domain class model of wildl<strong>and</strong> fire we focus on the<br />
fire behaviour dynamics. The system class model consists then in a fire propagation experiment. Finally,<br />
a solution is proposed through a conceptual mathematical model of fire spread. All these phases consti-<br />
tute a PIM of the model level of MDA <strong>and</strong> can be reused by other domain specialists.<br />
4.1 The domain class model<br />
Study of a wildl<strong>and</strong> fire phenomenon can be broken down into four packages (Fig. 4):<br />
1. The Human Action package encompasses development of wildl<strong>and</strong> fire prevention strategies<br />
including l<strong>and</strong> management <strong>and</strong> equipment policies as well as the elaboration of technical or<br />
regulatory solutions <strong>for</strong> reducing the number of wildl<strong>and</strong> fire ignitions <strong>and</strong> fighting fires;<br />
