Abstract:

The article presents a methodology for assessing the design availabilityof a modernized armored vehicle product. To carry out such an assessment, data on the structure, composition and design parameters of the product are used. An example of obtaining a design availability assessment and a preliminary calculation of reliability indicators at the stage of a working design using models for assessing the reliability of mechanical components and probabilistic modeling using the Monte Carlo method is given. Combining the results of assessing the reliability of mechanical components and assessing the maintainability by means of modeling the operating system through Markov diagrams, taking into account a variety of modes and states of the product, allows you to obtain a reliable assessment of the design availability and reduce possible risks of non - compliance with the availability requirements at the stage of operation of armored vehicles.

Abstract:

In this paper, a new approach is proposed for estimating the potential characteristics of the aiming equipment of small arms. To implement the proposed approach a duel - based discrete - event simulation model is developed. The main initial data for the model are the accuracy characteristics and time parameters of the “sight - weapon” system and target parameters. The estimated characteristics of the aiming equipment are the aiming accuracy and aiming time. Aiming equipment type independence and accounting both time factor and accuracy are the main features of proposed model. The simulation model evaluates the performance of the aiming equipment of small arms by means of combat efficiency calculation. A proposed model can be used to formulate the general requirements for advanced aiming equipment of small arms.

Abstract:

The article proposes a method for coordinating planning of the functioning of the joint orbital constellation of optical - electronic and radar observation spacecraft. The proposed method is based on the mathematical apparatus of the theory of multilevel hierarchical systems and is a four - stage procedure for finding a rational coordinated plan for the use of an orbital constellation of observation spacecraft, which makes it possible to increase the probability of solving the problem of observing a given group of objects. An algorithm based on the Danzig - Wulf algorithm used as an optimization algorithm with the organization of the computational process. This algorithm takes into account the hierarchical structure of the system and the coordinating solution in the subsystems based on the introduction of appropriate coordinating signals. This allows us to interpret the computational process as a process based on the modification of the objective function using the price mechanism.

Abstract:

The article discusses the actual problem of ensuring high - quality and operational information interfacing of heterogeneous automated systems for special purposes (ASSP). The task of multicriteria optimization was set, according to the result of the solution of which a technological basis was chosen for improving the information support of both existing and newly created ASSP in the interests of resolving the global contradiction between the unity of management activities and the disunity of individual control loops. An original version of the organization of the information interface of the ASSP is proposed. To develop a model of circulating information, the concept of mathematical structures according to Bourbaki was applied. The study of the efficiency of informational coupling of heterogeneous ASSP in the conditions of the use of improved information support has been carried out.

Abstract:

The article describes the methodological support for assessing the probability of recognition of typical aerial reconnaissance objects based on the linear resolution values on the ground, obtained from the results of flight tests of digital optoelectronic systems. The relationship between the recognition value of typical aerial reconnaissance objects and the value of their linear resolution on the ground has been established and experimentally confirmed. It is shown that the value of the linear resolution on the ground unambiguously characterizes the signs of recognition (decoding) of objects from digital images, regardless of the principle of image formation and external factors acting on it. The values of the linear resolution of digital optoelectronic systems on the ground have been obtained, which ensure the recognition of the type of aviation objects, objects of automobile and armored vehicles with a given probability. The priorities for the development of methods and systems for decrypting and processing intelligence information have been determined.

Abstract:

This article presents a methodological approach used in solving problems of evaluating the topological properties of networks, taking into account the determination of the importance of its features. This problem can be solved in the interests of recognizing the structures of information and telecommunications networks in order to assess the state of the control system of the object of study. The approach is based on the use of methods of the theory of mathematical statistics, namely, the method of principal components. The proposed solutions were tested using random graph models. The obtained results indicate the need to analyze the feature space to improve the accuracy of recognition systems when solving problems of assessing the state of the control system of a complex object.

Abstract:

The article presents two methods of express assessment of the technical condition of road bridges for reliability when passing super - heavy loads of the strategic missile forces (SMF) through water barriers. The method of comparing efforts allows us to quickly assess the possibility of using road bridges without damage to pass modern and promising superheavy loads of the SMF. The experimental and analytical method allows us to determine the technical condition by the reliability of girder road bridges of different static systems made of different materials taking into account their actual operational condition by the measured angle of rotation of their support sections.

attenuation of radio waves, ground wave, influence of the underlying surface

Abstract:

When solving problems of constructing maps of the power distribution of electromagnetic radiation (EMR) in the long - wave part of the spectrum, the main factor determining additional attenuation is the absorption of wave energy by the underlying surface. But in open sources, for the case of an electrically inhomogeneous surface, only a qualitative description of the dependence is given, which also requires a significant amount of operator participation. The latter makes it extremely difficult to automate such calculations, which is especially important when constructing maps of the distribution of the electromagnetic field strength. In this paper, we propose a method for calculating the power of the electromagnetic field in the ultra - longwave (ULW) and longwawe (LW) ranges, which takes into account not only the mixed nature of the sections with different conductivity, but also the relative location of these sections relative to the transmission and reception points.

Abstract:

The work considers training shooting complex requirements for combat weapons firing and technical solutions ensuring their fulfillment. Unlike traditional shooting ranges, the considered complex provides the safely fire in any direction. Therefore, it is necessary to develop reliable anti - ricochet structures excluding the ricochet at any angles of fire. The work considers technical solutions for anti - rocket structures, the complex as a whole and the results of their ballistic tests. The proposed technical solutions for the combat weapons firing training complex meet the requirements for such structures: modularity, variability, low - operating costs, maintainability, effectiveness of the educational process.

Abstract:

The article deals with the task of forming the optimal composition of the security forces for the effective implementation of the task of ensuring the physical protection of an important state facility. To solve the problem, we use the mathematical model of the knapsack problem, which is part of the mathematical programming models and the theory of fuzzy sets. A procedure is proposed that allows determining the optimal solutions when forming the composition of the security forces of an important state object and thereby ensuring the effective implementation of the task of physical protection of this object, depending on the cost of staffing these objects with personnel and the level of competence of the employees involved. The application of the proposed procedure is considered on a practical example, which allowed us to determine the feasibility of its use in solving problems of this type.

Abstract:

A significant number of solutions have been developed to protect against DDoS attacks. With the combination of these methods, their implementation or readiness for use, it remains likely that from any place of the information and telecommunications system, it is possible to implement a DDoS attack on the elements of the corporate management system. The article presents a method for the synthesis of an information and telecommunications system that excludes the implementation of DDoS attacks on elements of a corporate management system during their operation. With the help of the developed methodology, it is possible to obtain data on the parameters of the transport network and access network, when using which the possibility of implementing DDoS attacks on elements of the corporate management system is excluded. The methodology is intended for officials who ensure the process of planning, deploying and functioning of the corporate management system.

Abstract:

The armored glasses, their types, construction and optical properties, as well as their changing over time are examined in the paper. Special attention is given to the «ageing» of glasses, the process, that causes significant deterioration of their ballistic characteristics. The influence of this process on their optical properties is also shown. The paper describes the method and the equipment that were used for measuring spectral transmission coefficient of armored glasses. The measurement results of the optical properties of the 3rd class protection glasses are presented below. During the research a relationship between the changing of spectral transmission coefficient and operating time was revealed. The spectral bandwidths that show the most pronounced change of the spectral transmission coefficient were determined and the requirements for radiation sources that can be used in these bandwidths were established.
