Unmanned aerial vehicles have firmly entered our lives. They are used in various fields, not an exception is the scope of search and rescue operations. The EMERCOM of Russia purchases and uses various unmanned aerial vehicles. For operational use, helicopter-type vehicles are most often used, which also include quadrocopter-type vehicles that use four main rotors that provide lift. Different quadrocopters have different characteristics and parameters. When purchasing quadrocopters, they primarily focus on the characteristics, parameters and cost of the devices. At the moment, there are no methods for a comprehensive assessment of the parameters of unmanned aerial vehicles. Within the framework of the study, a method of integrated assessment based on the application of the Pareto method is proposed, on the basis of which optimal unmanned aerial vehicles are identified. The practical significance of the results lies in the possibility of forming requirements for the purchase of unmanned aerial vehicles for the units of EMERCOM of Russia, taking into account the optimality of characteristics and cost.
