The article describes a new method of describing wildfires spreading and extinguishing based on agent-based models. The agent approach in conjunction with geoinformation systems (GIS) permits to efficiently describe the interaction of a big number of participants of wildfire fighting: spreading fire, fire brigades, means of mechanization, air means, etc. In the current paper, this approach is illustrated by an example of two types of agents denoted as A and B. The burning fire line is seen as a chain of type A agents, each of which imitates burning of an elementary area of vegetable fuel. The fire line movement is described by Hamilton–Jacobi equation and is calculated based on the moving grid algorithm. Agents of another type—B-agents—describe fire extinguishing, they approach the agents of A type and affect them decreasing fire intensity to zero. This model is presented by a GIS-oriented software system which may be enhanced and be useful both for fire control management and training personnel in wildfire fighting tactics.
