New algorithm for calculating the required number of unmanned aerial vehicles and the duration of their stay in dangerous area

This paper proposes a new approach to calculate the time spent by unmanned aerial vehicle (UAV) in dangerous area with consideration of maximum allowed probability losing UAV and increasing rate this given area. Unlike known approaches, which are based on flying around areas, it is proposed cross boundaries for defined time, calculated allow obtaining required data set about interested Based loss probabilities estimates, an planning number UAVs group flight substantiated, taking into account them. The formula calculating UAVs, obtained approach, consists three terms, consider requirements pre-flight task accomplishment, high-quality in-flight service requests, as well necessary reserve case decrease performance. To evaluate quality algorithm, various different initial conditions determining stay zone considered. specified minimizes indicator. In addition, presents practical example where algorithm used observe territory UAVs. It shown that can determine study dimension, also each order reduce
