In this paper, we consider the Markov model of a multiserver retrial queue with an input flow rate that depends on the number of calls in an orbit and with a limited number of retrials. We have obtained the conditions for the existence of the stationary regime and presented formulas for steady-state probabilities. Our approach is based on the approximation of the input model by the model with truncated state space.

The article describes radio beacon systems and presents a mathematical solution to determine the location of an unmanned aerial vehicle (UAV) equipped with a direction-finding device. This system ensures continuous flight and allows for determining the exact coordinates of targets, regardless of satellite signals. It facilitates the successful completion of combat missions in adverse weather conditions and when using radio electronic warfare (REW) systems based on signals received from radio beacons.

A method for estimating the optimal rated power of a photovoltaic plant for powering the main drainage of a closed mine is proposed. As an optimization criterion, the approach to zero of the annual balance of payment for electricity was chosen. This approach will significantly reduce the burden on the community budget. The implementation of the optimal configuration of the power plant will ensure the maintenance of the balance of mine waters in post-coal regions and reduce the likelihood of flooding, soil subsidence, and waterlogging of land.

Technogenic factors that affect urban area flooding development, forecasts of improving groundwater level changes, and comprehensive management of urban groundwater must be taken into account and controlled. A three-dimensional mathematical model of groundwater level changes in cities has been developed, which takes into account atmospheric water infiltration, additional groundwater replenishment, transpiration, evaporation, evapotranspiration, and groundwater intake.

With the emergence of unmanned aerial vehicles, the assignments of combating them have also become significantly more relevant. Today, operational countermeasures against UAVs are of great importance. Modern UAVs are capable not only of conducting video reconnaissance in a certain area, but also of observing a specific object for a long time and striking it. After detecting and identifying UAVs by RLS, it is necessary to take measures to neutralize them. In the paper, a mathematical model of the evaluation of the dead zone of RLS working together for the effective detection of unmanned aerial vehicles was established and a comparison of the dead zone was made on concrete examples. The purpose of the research work is to solve the problem of effective placement of joint working RLS by mathematical methods for nonobserved remaining part of them had minimal volume and to select the necessary placement scheme.

Plotting position formulas provide a non-parametric means to estimate the observed hydrological data probability distribution. In particular, using a plotting position formula, a plot of the estimated values from a theoretical parametric probability distribution can be compared with the observation data. It allows an examination of the adequacy of the fit provided by parametric probability distributions. However, results of calculating empirical annual probabilities of exceedance observed maxima water discharges show an increase in the divergence between the estimates obtained using the different plotting position formulas in case of more extreme events. Thereby, the choice of a relevant plotting position formula becomes a challenge. Different plotting position formulas may be admissible options. This article shows that the divergence between the plotting position estimates can be extrapolated to predict design maxima water discharges of low exceedance probabilities.
