Annotation:

The paper proposes a methodology based on the provisions of the theory of nonsummable mathematical measures of fuzzy set theory, the methods of eigenvectors, paired comparisons and non-summable measures of Dempster and Schaefer, which allows for the calculated complex indicator of the technical level of space technology samples to determine a justified range of values satisfying it. The proposed approach allows us to abandon the requirement that the sum of the weighting coefficients of the components of a complex indicator be equal to one, which reduces the influence of subjective factors on the result. The results of testing the methodology are presented using the example of comparing spacecraft as complex technical objects, conditionally belonging to the same class, and the features of its use in scientific and technical support of research and development work on the creation of promising models of rocket and space technology.

Annotation:

The possibility of using a local radio navigation system (LRNS) to ensure the positioning of a marine vessel (MS) along the route with the necessary accuracy in places where global satellite RNC signals may contain natural interference, and the geometry of movement of the elements of the Satellite Radio Navigation System (SRNS) may not be sufficient to meet the requirements for determining the location with the required accuracy, is relevant in the present tense. The presented paper discusses the principle of constructing a local radio navigation system for positioning small-sized naval vessels at a range of up to 100 km with a standard deviation of no more than 1 meter. Rational options for the placement of the reference stations of the LRNS are proposed to ensure the required accuracy, and the problem of estimating accuracy is solved by processing measurements using the method proposed in the work using both equal-precision and non-precision measurements.

Annotation:

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.

Annotation:

The article proposes a model for processing tasks with variable computational complexity in a distributed environment with a software-defined architecture. The model is based on three key components: a negative request mechanism for congestion management, container virtualization for dynamic resource scaling, and queue network theory for performance analysis. The model of representation of processes for processing tasks with dynamic labor intensity in a distributed computing environment with a software-defined architecture sets itself the task of optimizing computing processes, managing computing resources and ensuring minimal task execution time. Such a model should ensure high productivity, efficient resource management, and automation of adaptation processes to changing conditions. The main focus is on dynamic resource management under unstable load.

Annotation:

The article addresses the challenges of modeling elements of the background-target environment and their causes. For given parameters of an electro-optical system, an expression is derived that enables the creation of star samples using a standard uniform random variable sensor, where the brightness distribution aligns with actual astronomical data. A method for modeling uncataloged stellar background («scoop method») based on the assumption of uniform star distribution in space is proposed. An expression for the total number of stars within a spherical region of a certain radius is obtained. This expression accounts for the non-uniform distribution of stars in the Galaxy. Mathematical analysis provided optimal samples reflecting the actual distribution of stars by brightness within the system's field of view. Under the given assumptions of stellar statistics equations, an expression for the total number of stars in a spherical region of space of a certain radius is derived.

Annotation:

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.

Annotation:

The article discusses proposals for ensuring the stability of management by improving and using engineering barriers, means, and techniques for simulating management system objects, which can be used to ensure their security and other infrastructure objects. Taking into account the situations discussed, these proposals allow for an increase in the number of surviving personnel by 6–8 %, equipment by 15–20 %, and the justification of the composition of the complex of means for ensuring the security of the management system object. The developed proposals for ensuring the security of management system facilities by improving their imitation allow for a 22–24 % reduction in personnel losses and a 30–35 % reduction in equipment losses. The implementation of measures increases the stability of the management system's functioning, and the greatest effect can be achieved through the comprehensive use of the considered means and methods.

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.

Annotation:

The article presents an algorithm for the collective distribution of targets by a group of UAVs designed to monitor the occurrence and development of emergencies of natural and man-made origin. The development is based on the use of a control digital twin, which provides a fundamentally new approach to coordinating unmanned systems. The essence of the proposed solution is to create a multi-agent control system, where the virtual space of the digital twin becomes a platform for generating control actions. This approach allows you to transfer complex computing processes to a virtual environment, while maintaining the responsiveness of the entire group to dynamically changing emergency conditions, which is especially critical in disaster recovery.

Annotation:

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.

Annotation:

Until now, the identification of the dangers of military labor is carried out mainly in the format of ongoing monitoring of the conditions of daily activity of military personnel, when the effectiveness of the developed preventive (corrective) measures is low. It is much easier and more efficient to solve this problem, as is known, at the stages of designing and creating samples of weapons and military equipment. Nevertheless, the procedure under consideration at the specified stages of the life cycle of military equipment facilities is carried out in a very narrow range of military labor factors, which does not allow us to form a comprehensive matrix of actual hazards in their entirety at each workplace. As a result, some dangers and the associated risks of damage to the health of military personnel remain unaccounted for and, consequently, uncontrollable.

Annotation:

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 issue of using a fortification complex consisting of sequentially placed Loza products and bulk gabions for equipping critically important objects, weapon positions, military and special equipment in order to protect personnel, combat equipment, transport and material resources from anti-tank cumulative grenades of hand-held anti-tank grenade launchers. The protective characteristics of the complex were confirmed during full-scale tests by firing PG-7VL grenades at it. As a result of the tests, it was established that the elements of the PG-7VL grenade, after the activation of its warhead on the Loza product structure, are retained by the bulk gabions without damaging their rear part.

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.
