Methodology for determining the rational number of UAVs taking into account their reliability in emergency situations

Abstract

Creating a system of control and analysis of emergency situations is an important task for most countries of the world. Currently, projects have been initiated to analyze, assess the occurrence of emergency situations, generate data for the development of architecture, demonstration analytics and prototype decision support capabilities, taking into account the use of currently available data and analytical methodologies to prevent accidents and incidents. Unmanned aerial vehicles (UAVs) that work with ground and air control points in emergency situations are planned as the basis for the construction of such a system. Existing approaches to building such a system involve structural and numerical redundancy of UAVs. There are well-known methods for estimating the probability of completing the task of a fixed number of flotillas, taking into account the reliability characteristics of UAVs. This approach involves the maximum redundancy of the grouping, as well as the use of highly reliable aircraft, and therefore expensive UAVs, and does not allow quasi-optimal construction of UAV flotillas. The report proposes a methodology for determining the rational number of UAV fleets, taking into account the tasks and characteristics. The obtained results make it possible to estimate the quasi-optimal number of the UAV fleet, taking into account the reliability of the characteristics of the aircraft for the performance of assigned tasks in emergency situations.
