Mathematical Modeling of Knowledge-Intensive Products Export Energy Costs

This article presents the mathematical modeling of export energy costs. The knowledge-intensive products export energy costs are a set of financial, material, labor costs and resources consumption. Export costs are a multilevel system of indicators. The author sets out the order of mathematical modeling. At the first stage, the main trends in reducing export energy costs are identified. A set of integrated logistics support measures is modeled. The modeling of knowledge-intensive products export energy costs is a system of technical and economic indices and a cost value dependance: Maintenance and Repair, Material and Technical Maintenance, Business Model of After-Sales Service, Formation of the Cost of Insurance and Investment Management Strategy. Formulas, practical calculation examples and graphs are presented. The Ishikawa systematic analysis method is used to visualize data and dependence relations. The author's mathematical modeling of knowledge-intensive products export costs includes the calculation of integrated logistic support costs. Exporting countries require a high level of technical products efficiency. It has been established that "the more complex a knowledge-intensive products is, the higher the reliability of systems is". Reliability indices are basic. The author's scientific study confirms a hypothesis of the knowledge-intensive products export feasibility only with high reliability and efficiency factors. The author developed a set of integrated logistical support measures for knowledge-intensive products.

Calculation of the salary and key provisions of the methodology for determining the total costs of technical service of machinery and equipment in animal husbandry

The initial data for calculating the basic salary are: the labour intensity of carrying out maintenance and repair of machinery and equipment in animal husbandry, as well as hourly tariff rates for workers in workshops and areas for the repair of agricultural machinery and tools, which are accepted directly in farms and repair and maintenance organizations independently, but not lower than the tariff rate has been established for budget organizations. The purpose of the work was to calculate the basic salary of personnel according to the tariff categories used in the Republic of Belarus, and to consider the key provisions of the methodology for determining the total costs of technical service of machinery and equipment in animal husbandry. The most important provisions of the methodology for calculating the basic salary of personnel of repair and maintenance departments and organizations operating in the livestock subcomplex of the Agro-industrial complex of the Republic of Belarus have been presented. The main points of the methodology for calculating the total costs of maintenance and repair for machines and equipment of livestock farms and complexes have been given in relation to the conditions and their own features of accounting and planning of repair and maintenance work in domestic animal husbandry. An example of practical calculation of costs for carrying out various types of maintenance and repair of a widely used domestic milking machine has been considered.

Method for practical calculation of underwater vehicle's television communications

В статье обосновывается и предлагается для практического применения методика расчёта подводных телевизионных коммуникаций, апробированная при проведении испытаний отечественных подводных аппаратов на морских акваториях Белого и Баренцева морей. Последовательно проводится расчет освещенности толщи воды между осветителем и объектом наблюдения; определяется суммарная освещенность на входе объектива телевизионной камеры, создаваемая отраженным от объекта светом и помехой обратного рассеяния; рассчитывается контраст белых и черных объектов. В заключении показан расчет изменения пороговой чувствительности камеры в зависимости от дальности наблюдения. Представленная методика может использоваться при проектировании систем технического зрения обитаемых и необитаемых подводных аппаратов для получения данных о предполагаемых дальностях наблюдения объектов с различными коэффициентами отражения с заданными параметрами прожекторного осветителя. The article proposes a technique for calculating underwater television communications, which was confirmed during tests of domestic underwater vehicles in the waters of the White and Barents Seas. First, the illumination of the water between the illuminator and the object of observation is calculated; then the total illumination at the entrance of the TV camera lens, created by the light reflected from the object and the backscattering interference, is determined; and finally, the contrast of white and black objects is calculated. In conclusion, the calculation of the change in the threshold sensitivity of the camera depending on the observation range is shown. The presented technique can be used in the design of computer vision systems of crewed and unmanned underwater vehicles to obtain data on the estimated observation ranges of objects with different reflection coefficients and with the specified parameters of the searchlight illuminator.

DEVELOPMENT OF UKRAINIAN ENTERPRISES IN CRISIS ECONOMY IN BRAND MANAGEMENT SYSTEM

The purpose of the article is to improve and deepen the theoretical aspects of brand value assessment methods, highlighting their advantages and disadvantages, combining existing techniques for more effective assessment of the enterprise, the practical calculation of the brand value "Kiivkhlib" on the example of the Ukrainian enterprise-leader of the baking industry. In the article the theoretical analysis of publications, which considered the main aspects of the brand management system at the enterprises, in particular domestic ones, was carried out. The authors also highlighted the subject of the research, which is the given factors and structural elements of brand identity and value from the side of strategic activities of companies that operate in two Ukrainian markets – the market of milk and dairy products and the market of bakery and bakery products. Methodology. To determine the brand value was chosen one of the enterprises in the bakery industry, located in Kiev – "Kiivkhlib". The calculation was carried out using a combination of methods "Interbrand Model" and the method of royalty based on the data of the public accounts of the enterprise for 2019. Determination of the index of the brand role was carried out by expert method using seven basic criteria (leadership, stability, market, internationality, trends, support, protection). The last step was the calculation of the final brand value, where the brand profit is defined as the product of the intangible profit value and the brand role index. Also to calculate the final brand value, it was necessary to calculate the discounted cash flows over the years of the economic life of the investment. Results. As a result the index of brand role added up to 86%. As for "Kiivkhlib" it was determined that the brand multiplier value of 18,8 corresponds to a point estimate of brand strength (86 points). The results obtained by using the method based on "Interbrand" model showed that brand value of "Kiivkhlib" is at the level of 5093,1 thousand UAH. Due to the fact that this model involves a large number of subjective estimates, the results may differ from the calculations obtained by using other methods and models. Practical implications. The value of the brand affects both the financial aspects of the enterprise and its non-financial side. It is worth noting that the brand is an intangible asset but it provides a real financial result in the form of profit. That is why companies, seeking to gain a leading position in the market, should pay close attention to assessing the brand value and using the obtained data in strategic management.

Experimental Study of Square CFST Stub Columns With a Low Steel Ratio Under Axial Loading

This paper presents an experimental and numerical study on large dimension concrete-filled square low steel ratio steel tubular (CFST) stub columns under axial loading. Four specimens were designed to investigate the effects of steel ratio on the confinement effect of square CFST stub columns with a low steel ratio. ABAQUS was used to establish 3D finite element (FE) models for simulation of square CFST stub columns with a low steel ratio under axial loading. Furthermore, based on the experimental verification, the definition of the confinement index (ϕ = fsAs/(fcAc)) was discussed and the effect of the grade of concrete and steel tube was also investigated. With the same cross-sectional dimensions, the confinement effect of the square CFST stub columns with a low steel ratio (less than 0.05) was better than the others. The stub columns with the yield strength of steel tube fs = 235 MPa (345, 420 MPa) and compressive cubic strength of concrete fcu = 40 MPa (60, 80 MPa) can give fully demonstrate the material performance and reflect the better confinement effect. Based on the experimental results and FE modeling, a practical calculation formula for the ultimate load-carrying capacity of square CFST stub columns with a low steel ratio was proposed. The formula calculation results presented in this paper show good agreement with the experimental results. Compared with the existing formulas, the proposed formula has better precision.
