Floods are the most frequent natural disasters in the world. In the system of warning and flood protection of areas at risk of flooding in the event of its occurrence, it seems advisable to initially work out the possibility of evacuating the population, animals, equipment, material values, etc. In this article, a methodology for determining destinations (points of destination) for the evacuation of people and equipment from a predicted flood zone (of a natural disaster) to a safe area is proposed based upon the criterion of the shortest possible distance. In the paper, a scenario is considered that involves the contours of the flood zone boundaries for several variants of the intensity of the probable development of future events (with the aid of geoinformation technologies), and the coordinates of the objects to evacuate are permanent and known in advance. With the known coordinates of the objects and the closest points of the boundary of the predicted flood zone, the shortest distances can be calculated. Based on these calculations, the appropriate destinations for evacuation are determined. The proposed methodology can be used for flood forecasting and flood zone modeling to assess the economic and social risks of their aftereffects and to allow the public, local governments, and other organizations to better understand the potential risks of floods and to identify the measures needed to save lives and avoid damage to and loss of property and equipment. This methodology, in contrast to known approaches, allows the determination of the nearest locations for the evacuation of people and equipment from a flood zone (of a natural disaster) to safe areas, to be determined for several variants, depending on the possible development of future events. The methodology is algorithm-driven and presented in the form of a flowchart and is suitable for use in the appropriate software. The proposed methodology is an introduction to the next stages of research related to the determination of safe places for evacuation of people and their property (equipment) to safe places. This is especially important in case of sudden weather events (flash floods).

The article considers the development of a heavy-class robotic ground combat system based on the BTR-4E armored personnel carrier. Analysis of samples the heavy class combat robotic ground complexes showed that they can be developed on the basis of serial crewed military vehicles HMMWV (AM General), M-ATV (Oshkosh), BMP-3 (Russia), T-72 (Russia), M113 (Israel), Patria AMV (Finland) or create a new design MDARS (AM General), Black Knight (BAE Systems), "Uran-9" (Russia), TYPE-X (Milrem Robotics). They are made on a tracked or wheeled platform. What unites this class of robotic ground combat systems is a remotely controlled combat module with a 25-30 mm cannon, anti-tank guided missiles, a machine gun and a grenade launcher, which can be controlled from a distance. A comparative analysis of the tactical and technical characteristics the BTR-4E armored personnel carrier with military vehicles with a 30 mm cannon in service with the Armed Forces of Ukraine has been performed. As a result, the choice of BTR-4E armored personnel carrier as the basic crew unit for the construction of a heavy class robotic ground combat system has been substantiated. The analysis of the design of control drives of the power plant, transmission, braking system, steering system and combat module installed on the BTR-4E armored personnel carrier was carried out in terms of the possibility of implementing remote control of movement and fire. The structure of a combat ground robotic complex based on the BTR-4E armored personnel carrier with different variants of remote control panels, means of establishing communication channels and construction of a remote control station is proposed. For example, the driver's remote control panel may be designed on the basis a tablet or on the basis a simulator for full simulation of control commands. Remote controls for the commander and gunner can be designed on the basis of regular controls and be similar to them for quick training of the crew to work. Communication between remote control units and the controlled armored personnel carrier can be arranged using ultrashort-wave radios or via the 4G, 5G mobile network. The remote control point can also be developed on the basis a BTR-4E armored personnel carrier, a military vehicle or deployed on the ground. It depends on the concept of application of the heavy class combat ground robotic complex.

In this paper the method for determination of the object’s elevation on the ground as well as the mathematical model for error estimation of object’s determination are suggested. It is assumed that the object is situated beyond line-of-sight or, whatsoever, beyond the horizon. It has been obtained the analytic expression for error estimation of the object’s elevation determination using flying platform in case of the known inaccuracy of goniometry and distance measures. The effect of inaccuracy of goniometry and distance measurements on the error estimation of the object’s elevation determination is traced. Analytic expressions of evaluating requirements for accuracy of goniometer and distance measurer are deduced. These requirements will ensure the specified accuracy of the object’s elevation determination. A relationship between object’s elevation determination and its location with respect to the observing station and flying platform is investigated.

Based on the analysis of existing approaches to the modeling of demining processes, the use of reconnaissance kits and demining of the area, in order to determine the variant of the kit, it is necessary not only to compare their parameters, but also to determine the relative personal indicators of the characteristics of these kits. To determine them, the method of expert evaluations, namely ranking, was used. Determining the significance of relative personal indicators of the characteristics of mine clearance kits can cause some problems, which largely depends on the individual skills and experience of the expert. The lack of standardized metrics, in relation to generally accepted standards for reconnaissance and demining kits, can make it difficult to compare indicators between different experts. The lack of a clear methodology can lead to ambiguity and unpredictability in the assessment. The article presents a partial method of relative values of personal indicators of the characteristics of demining kits using the method of expert evaluations. The proposed partial method allows you to determine the coefficients of relative personal indicators of the characteristics of demining kits. Based on the theoretical provisions presented in the study, a methodology for processing the results of the expert survey is proposed. At the end, the numerical values of the coefficients of relative personal indicators for a typical demining kit were obtained and the direction of further research was formulated.
