MATHEMATICAL MODEL OF UNDERWATER DEMINING OF AN EXPLOSIVE HAZARDOUS OBJECT

The process of developing a mathematical model of the process of demining an explosive object located at depth is considered. Based on the above, the aim of the work is to develop a mathematical model of the emergency response process associated with the underwater location of an explosive object, as a process of functioning of the system "PNS - special means of underwater demining - diver-sapper", which should be the basis for -technical recommendations for improving the efficiency of underwater demining by divers. To solve this goal should solve the following main tasks: to determine the initial and boundary conditions for the functioning of the mathematical model; describe the process of underwater demining in the form of a multifactor model; to present options for the use of forces and means of underwater demining in the form of one-factor models; to determine the order of analysis of weighting factors in the obtained models. This task shows the feasibility of considering such a process in the form of a complex ergatic system "diver-sapper - special means of underwater demining - underwater location of an explosive object". simulation experiment, which will take into account the nonlinear influence of the components of the system, as well as their relationship with each other, on the effectiveness of underwater demining. It is shown that the mathematical model of underwater demining by a diver-sapper is a system of three analytical dependences. The first is a functional that describes the process of underwater demining in the form of a three-factor polynomial model. The second allows us to present this functionality as a set of one-factor models. The third provides the definition of weights in solving a multifactor problem. It is noted that such a model allows to proceed to the substantiation of operational and technical recommendations, which will take into account the impact (in that case nonlinear) not only directly of each individual indicator, but also the effects of interaction between them. Key words: emergency situation, underwater demining, multifactor assessment, operational and technical recommendations.
