Grab M. Models, methods and algorithms of forest fires spreading

Object of research is forest fire. The purpose of work is the development of models, methods and algorithms of forest fire spresding, which would allow to reduce the losses from fire, namely to reduce the burned area, to reduce expenses for fires extinguishing, to reduce threat to life of the people. Methods of researches. In a basis of the description of forest fire dynamics the probabilistic-multiple method of Monte-Carlo is fixed. The cartographical information about forestry was submitted with the help of a method of level-by-level organization of the spatial data. Binding of the equations, which describe the physical laws, to discrete elements of a fire zone is executed with the help of a numerical method of control volumes. For formalization of the poorly structured entrance data the methods of mathematical logic were used, namely multisort logic of predicates of the higher order and modal aletic logic of the higher order combined with temporal logic. Results of work applied as a package of theprograms.
