The methodology of optimization of technologies of extinguishing of forest basilar fires and facilities of mechanization is offered for their implementation on the basis of minimization of expenses on extinguish-ing and ecological damage. The method of determi-nation of set of optimal technologies of extinguishing forest fires has been worked out. Technical means which application will allow localizing and extinguish-ing forest fire with maximum efficiency have been revealed. Initial analytical formulas allowing in pa-rameters of the fire and technology of its suppression to count the terms of suppression and the sizes of the burned-out forest areas are shown out. The concrete list of the equipment for extinguishing of forest fires depending on the parameters of their development is set out. Insignificant parameters of the fires for the solution of the problem of optimization the technolo-gies of suppression of the centers of burning of high, average and low intensity are filtered. The method of definition of optimum technologies is based on shown out formulas of calculation of optimum technologies of suppression and calculations of costs of perfor-mance of work. Full search of options and neural network algorithm is used. The application of neuronets allowed not to pay attention to insignificant parameters of the fires and to receive simple formu-las for the solution of the task taking into account the analysis of occurrence of technologies of suppres-sion. In the array of information received when per-forming calculations optimum technologies of sup-pression according to the set criteria. As a result of application of neuronets and simple formulas for the solution of set problem of the most optimum technol-ogies are received. The use of optimized technolo-gies of suppression of local forest fires at various stages of their development will allow services of for-est protection to organize the performance of work with rational number of forces and means and also with minimum expenses and damage.
