Глобальна інформатизація сучасного суспільства, розвиток телекомунікаційних, комп’ютерних та інформаційних технологій – з одного боку, та потужні виклики до всього людства, на кшталт безпрецедентного повномасштабного вторгнення російських окупаційних військ на територію незалежної України 24 лютого 2022 року з метою знищення суверенної держави та її народу – з другого, обумовлюють суттєві зміни пріоритетних форм здійснення освітнього процесу; і дистанційне навчання в цих умовах стає єдиним можливим варіантом надання якісних освітніх послуг при мінімальних фінансових витратах на його організацію. У зв’язку з цим в умовах воєнного стану Міністерство освіти і науки України проводить інтенсивну роботу з напрацювання дієвих сценаріїв розв’язання проблем у забезпеченні дистанційного освітнього процесу цифровим контентом, пристроями, технологіями, удосконалює та уніфікує в цьому контексті низку освітніх інформаційних систем і централізованих інформаційних баз. Міністерство освіти і науки України має попередні домовленості, й ним уже розпочато амбітні активності спільно з низкою цифрових гігантів світового рівня, зокрема, Google, Microsoft, Zoom, Coursera, Udemy, edX, SpaceX, HP, Vodafone, Lifecell, Київстар тощо. Тому як ніколи актуальним стає завдання аналізу, дослідження, порівняння та структуризації інформаційних технологій (сервісів, платформ, програмних додатків, автоматизованих систем управління навчанням тощо) та навчально-методичних розробок у вигляді інструкцій, вказівок, рекомендацій, алгоритмів, методів, методик з ефективної організації та здійснення дистанційного навчання в закладах вищої освіти та вищих військових навчальних закладах України в умовах воєнного стану.

Attention is drawn to the lack in many municipal transport models of off-line testing engineering tools of on-board parameters and assessment of electromechanical equipment in real time. These development restraints are caused by stagnation of engineering decisions that can be eliminated with the help of the unlimited possibilities of modern microelectronics. It has been considered an example of thermal control of electrical equipment during its operations. The popularity of the thermal method of equipment control is confirmed by its application not only in transport, but also in electromechanical devices. It has been considered methods of using several thermal transducers for collecting data and forming matrices characterizing a certain class of breakdowns. The most important matrix is the initial one, which refers to the serviceable equipment at the beginning of equipment operations. Due to increased reliability of data, it is advisable to develop effective methods for selective selection of initial values. The paper drew attention to the possibility of solving such problems by software with the implementation of comparison methods, sorting options, etc. The peculiarity of algorithms development for such auxiliary operations is due to the possibility of creating data arrays for the practical identification of possible failures, both in individual parts of the equipment and in the set of components as a whole. It has been presented the results of the binary representation of intermediate and final information messages, which greatly simplify the implementation of diagnostic examination tools. Modeling in the Matlab environment confirmed acceptability of proposed engineering decisions adapted for their implementation by means of processors with RISC-architecture. Despite the fact that binary methods of breakdowns technical appraisal will always differ much more inaccuracy than those made on the basis of direct measurements, proposed autonomous local binary experts in onboard versions of their implementation in transport are less labor-intensive, do not require maintenance, are economical and may turn out to be good helpers to prevent possible equipment failures when operating vehicles on passenger service lines.

When preparing for and conducting combat operations of the “SA-13 Gopher” anti-aircraft missile system, commanders and combat personnel of the system must know the missile firing efficiency indicators [1–4]. As an indicator of missile firing efficiency, the probability of hitting a target with one missile is usually used. Massive homing is carried out via the contrast channel or the infrared channel of the missile homing head. Under various conditions of use, it is necessary to evaluate the detection ranges that are realised and the probability of timely target detection, launch range and missile launch probability. It is also necessary to imagine the possible values of the inclined distances to the far edge of the kill zone of the complex. The probability of hitting a target with a single missile is affected by the geometric dimensions of the targets, their colour and contrast in the infrared wavelength range, the presence of target designation, meteorological range of visibility etc. The task of determining the firing efficiency of the “SA-13 Gopher” anti-aircraft missile system when detecting targets through the optical sight and automated targeting is therefore relevant and important. Research presented in the published [1–4; 12–13] do not allow determining the value of the probability of hitting different air targets in various conditions of the complex’s use. This literature provides only general approaches to solving this problem for typical conditions of use of an anti-aircraft missile system. A numerical modeling technique for determining the firing efficiency indicator in the form of values of the probability of hitting targets by a missile has been developed. The modeling took into account the speed of the targets, their plane in the shooting picture, their radiating capabilities and meteorological visibility range, the quality of the combat work of the operators of the combat vehicle, the sun exposure and the closing angles of the combat vehicle. Found possible detection ranges and detection probabilities of a typical target and a small unmanned aerial vehicle (UAV). A high probability of the operator of a combat vehicle missing a typical target at low and medium flight altitudes was noted. Considered launch ranges of missiles that are implemented and the probability of launching a missile when targets are captured in the contrast and infrared channels of the homing head. The largest inclined ranges to the far boundary of the zone of damage of the complex were calculated. The values of the probability of hitting a typical target and UAV in various firing conditions are determined. Sufficient firing efficiency has been proven when capturing and launching a missile in the contrast guidance channel and firing at a typical target. A comparison of the contrast and infrared channels of the homing missile head when firing at UAVs was carried out. Analytical expressions for the calculation of missile firing efficiency indicators and corresponding graphic material are presented.
