METHODOLOGY FOR SUBSTANTIATING OPERATIONAL AND TECHNICAL RECOMMENDATIONS ON REDUCING THE TIME OF UNDERWATER DEMINING BY DIVERS-SAPPERS OF THE STATE EMERGENCY SERVICE OF UKRAINE

Abstract

The conducted analysis showed that an important and unresolved part of the problem of increasing the effectiveness of preventing emergency situations related to the underwater location of explosive objects is the lack of a methodology for substantiating operational and technical recommendations for reducing the time of underwater demining by divers-sappers of the State Emergency Service of Ukraine without reducing the level of personal safety composition
The application of systematic ergonomic analysis to represent the activity of a diver-sapper in the form of the functioning of the system "diver-sapper - technical support of underwater demining - underwater location of an explosive object", statistical methods of planning experimental studies and processing the obtained results, as well as mathematical and statistical methods of direct expert evaluations allowed to develop such a methodology, the basis of which is a multifactorial mathematical model of underwater demining by divers-sappers of the State Emergency Service of Ukraine. The methodology represents a set of the following sequential actions: - selection of options for operational activities (such significant factors as the level of preparedness of the diver-sapper; the conditions of the underwater environment in which the personnel work; the level of their equipment are highlighted); - direct expert evaluation of the execution time of the selected options in accordance with the 3x3x2 plan, taking into account the agreement of the experts; - determination of parameters of underwater demining models using standard formulas of the theory of planning experiments and verification of their reliability by comparing the extent to which real-world results obtained in conditions corresponding to a specific combination of selected factors fit into confidence intervals calculated with a reliability of 0.95 for the results application of multifactorial mathematical models of underwater demining with specific parameters; - analysis and simplification of models with subsequent ranking of factors both in the center of the factor space and at its edges; - substantiation of recommendations, substantiation of recommendations that are of an operational and technical nature, since the selected factors characterized both operational (personnel work under environmental conditions) and technical components of the underwater demining process, and their implementation.
