SCIENTIFIC SUBSTANTIATION OF THE GENERALIZED CRITERION FOR CHOOSING AN UNMANNED HELICOPTER-TYPE AIRCRAFT FOR EQUIPPING THE UNITS OF EMERCOM OF RUSSIA

The article presents a scientific justification for a generalized criterion for choosing an unmanned helicopter-type aircraft for equipping units of EMERCOM of Russia in order to improve the efficiency of operational tasks in emergency situations. The authors have developed a comprehensive methodological approach that integrates an expert assessment method involving five specialists directly involved in the maintenance and use of helicopter-type unmanned aircraft, a dimensional analysis method for the formation of dimensionless complex indicators, as well as a fuzzy logic apparatus based on the Mamdani fuzzy inference system in the MatLab mathematical modeling software environment. As part of the study, a survey of experts was conducted to determine the significance of the technical parameters of helicopter-type unmanned aircraft, the Kendall concordance coefficient was calculated, confirming a high degree of consistency of experts' opinions, the weighting coefficients of the parameters and weighted average estimates of six samples of helicopter-type unmanned aircraft were determined. A generalized efficiency indicator has been formed based on the integration of the technical efficiency indicator and a weighted average estimate. The results of the study made it possible to classify the considered samples of helicopter-type unmanned aircraft by efficiency levels and can be used in the selection of promising samples for equipping units of the Russian Ministry of Emergency Situations.
