Recently, there has been a rapid development of tools to improve the efficiency of
logistics systems based on a combination of flexible cooperation between the elements
included in their composition, the widespread use of digitalization and the adaptation of
the final product to the specific needs of a particular customer. Increasing the efficiency
of the clothing supply system makes the issue of the expediency of introducing digital
technologies relevant. The article examines the prospects for the introduction of digital
technologies in the material support system in general, and clothing support in particular
in the Armed Forces of the Russian Federation, as well as the development of software for
managing logistics processes, access to a single platform on which you can keep records of
assets and plan routes for the delivery of material.

The article is devoted to improving the safety of rocket and artillery ammunition storage
facilities. When managing the safety of objects, it is necessary to implement technology
of decision-making support, to apply modern possibilities for automation of management
processes. Implementation of decision support system will allow: reduce the time required
by the decision to process heterogeneous information and to develop the right solution;
analyze existing similar precedents and develop the optimal solution in the situation, reduce
the possible damage from emergency (prevent emergency emergencies). The method of
developing a system of decision-making support is considered on the basis of precedents.

The article examines the preliminary stage of information processing required for the
effective recognition of complex objects under conditions of data incompleteness,
uncertainty, and heterogeneity. The relevance of the study is driven by the increasing
demands placed on intelligent data analysis systems operating in non-standard and weakly
formalized environments. The proposed algorithm is based on the integration of modern big
data processing methods, including artificial neural networks, fuzzy inference mechanisms,
and the mathematical framework of Bayesian fuzzy networks. This combination enhances
the system’s robustness against external information distortions. The purpose of the article
is to describe the general architecture and functional structure of the software modules that
enable reduced data processing time without compromising recognition accuracy.

The article presents a developed mathematical model of an engine with an adaptive thermal
management system (ATMS) by varying the most significant external and internal factors
affecting the operation of the diesel engine cooling system. The developed mathematical
model provides the ability to control the elements of the diesel engine cooling system to
maintain the optimal coolant temperature, which ensures the lowest fuel consumption at
various operating modes, at different ambient temperatures and the dynamics of its change
due to the adaptive control of the cooling system elements (fan, water pump, electronic
thermostat and blinds). The article presents the derivation of the obtained equations and
control parameters of the diesel engine cooling system.

Within the framework of this work, a computational and experimental approach to
determining the actual technical condition of overhead power transmission poles is
proposed. The methodology developed with this approach in mind is a simple sequence of
numerical calculations, technical measures to inspect damaged elements and, if necessary,
repair individual overhead line structural elements. The peculiarity of the proposed
technique is that it additionally takes into account the features of deformation of overhead
line support structures during the destruction of individual elements, as well as operational
defects in the structures.

The article considers the issue of setting and confirming the requirements for the cockpit
door in order to prevent unauthorized access by third parties when committing illegal
actions to hijack an aircraft. The article presents test equipment with the corresponding
methodological support used in special tests of the cockpit door. The article presents
experimental data on the assessment of the protective properties of the cockpit door of
the Il-96-300 passenger aircraft in terms of bulletproof resistance to regulated means of
destruction, impact resistance to the door leaf, to the door in the area of the bolt, to the door
in the area of the hinge, as well as the pulling load applied to the door handle.

It is shown that a reliable assessment of the characteristics of a complicated radioelectronic
system (CRES) can be achieved only by combining the results of field tests and model
experiments. A formula has been obtained for the optimal a priori number of model
experiments with a limited volume of field tests and a given accuracy in estimating the
characteristics of CRES. The a posteriori number of model experiments is specified when
determining the «consistency» of the results of a joint assessment of the characteristics
of CRES based on the results of field tests and model experiments using the Smirnov and
Lehman-Rosenblatt criteria.

Dimensional analysis and the level of interchangeability of assembled products determines
the durability and reliability of special-purpose equipment. The number of products in
the manufactured batch and the number of links in the dimensional chain affect their
assemblability of an individual product. The probability-theoretic method is recommended
for calculating multi-link assembly dimensional chains. A method for estimating the
probability of successful completion of a separate piece of special-purpose equipment is
proposed. The methodology takes into account the number of products in the manufactured
batch, the confidence intervals of the true arithmetic mean of the size and the true mean
square deviation of the size of the component link of the assembly chain. A multi-link
assembly chain is calculated, an increase in the probability of successful completion of a
separate product with an increase in their number in the manufactured batch is established.

One of the ways to ensure the predicted reliability of the main ASUNO modules is to form a
rational set of spare parts at the design stage, which will increase its reliability by increasing
its technical resource. Based on the results of forecasting the possibility of increasing
the technical resource of the main modules, recommendations have been proposed for
calculating and forming a rational composition of spare parts for the automated guidance
and fire control system (AGFS) in order to calculate two types of sufficiency indicators:
the average delay time in meeting requests for spare parts with the ZIP-G kit and the
availability coefficient of the ZIP-G kit relative to the jth sample from the serviced group
of products. The analysis of the results shows that the proposed rational compositions of
the ZIP-G kits allow for an increase in the sufficiency indicator of stocks.

Experts are increasingly considering hydrogen-air fuel cells (FS) as a source of autonomous
power supply for military and special equipment. When using FS, the issue arises of
providing a reliable source of hydrogen. In this work, research has been conducted on
ways to create efficient hydrogen generators (HG) based on hydride compounds to ensure
the operation of hydrogen-air FS. Experimental samples of HG with a flow reactor and
a batch reactor have been developed and manufactured, which are not inferior in their
characteristics to similar developments described in the literature. The optimal design and
manufacturing technology of HG has been developed. Experimental samples of two types
of thermal power plants have been developed and manufactured, capable of FS with a
power of 20 Watts for 3 hours while consuming 18 g of sodium borohydride.

The article considers the results of modeling the operation of a cumulative gas generator
accelerator, conducted in the interests of studying the influence of the initial position of the
space debris particle simulator on the velocity achieved by it after a given period of time.
Various cases of the initial location of the space debris particle simulator relative to the
gas generator section are considered. The dependences of the simulator velocity change on
time are shown. The influence of the shape of the conical part of the gas generator on the
final velocity of the simulator is considered. The obtained results can be used to justify the
characteristics of the cumulative gas generator accelerator for the purpose of implementing
a full-scale modeling of a high-speed collision of a space debris particle and elements of
the spacecraft design.
