The article is devoted to the definition of rational decisions on the choice of emergency rescue equipment for carrying out rescue and other urgent work on low-volume and dispersed objects using the methods of mathematical programming. The criteria for the efficiency of RT (rescue technique) operation during the mechanization of ER (Emergency Restoration) related to the implementation of measures to minimize the time and material costs of their implementation are determined. The scientific and practical tasks aimed at increasing the efficiency of mechanization during the ER are discussed. Various technologies for conducting ER using mechanization methods are proposed depending on the specific reduced costs. We consider numerical methods for solving multidimensional extremal problems: a method of enumerating variants, a linear programming method, a nonlinear programming method, a stochastic programming method. Formed indicators of the effectiveness of rescue equipment. A systematic approach, formed from two stages of the search domain principle, is given. A model of the duration of the time of the technological processes of emergency rescue equipment is displayed. For the payoff matrix, the behavior of participant A is determined by the maximin function, and for participant B, the minimax principle. It is determined that four typical situations of using rescue equipment in different climatic conditions with different characteristics of the loading material and the loading range are most likely.
