Using the model of coordinated production planning allows to solve the following problems consistently and iteratively: basic coordinated production planning in conditions where demand is known; optimal planning that takes into account random external demand, which results are deterministic input parameters for the first task; optimization of the system test viability of business networks by controlling domestic product prices, the results of which are inputs for the second task.Â Â
New Approach for Estimation of Zonal Efficiency of Air Exchange Organization
Authors: Dovhaliuk Volodymyr , Mileikovskyi Viktor , . . 
Published: July 2024

Energy efficiency of buildings is dependent on air exchange organization. There are different methods for efficiency estimation of it. As it is shown in literature review, they have significant limitations including non-obvious physical meaning, which cause problems in validation of the results. Certain of them are not acceptable for zonal ventilation in rooms. Previous authorâ€™s work introduces new approach for the efficiency estimation of air exchange in a single-zone or multi-zonal rooms, which has obvious physical meaning â€“ relation of demands and supplied potentials. It provides the efficiency value for whole room only. In this work, by the similar approach, a method is proposed for estimation of zonal air exchange efficiency in different kind of rooms for each occupied zone separately. Additional definitions are introduced for the parameters and demands estimation in each occupied zone. The example of efficiency estimation of air exchange in a museum room with constant air volume system of air conditioning is solved. Sheltering of the keeping zone is recommended for the maximum air exchange efficiency.Â Â

Improving Bank Transparency in Assessing Financial Stability of Ukraineâ€™s Banking System
Authors: Ptashchenko Liana , Volkova Nelia , Volkova Valeriia 
Published: July 2024

The paper focuses on solving the problem of banks transparency in assessing financial stability of Ukraineâ€™s banking system under economic instability. The financial crisis in the country calls for developing a methodology supply for assessing financial stability of both individual banks and the banking system as a whole. We believe that the methodical tool for studying the financial activity of a banking institution should provide a bank with the opportunity for a long-term development rather than for the coming years. This is a priority task of a bank because under unstable economic development the reliability of a bank decreases as well as its competitiveness and adaptability to the internal and external destabilizing factors. The topicality of the issue is determined by the fact that increasing financial sustainability is one of the important measures, the quality of which predetermines banksâ€™ financial results. Presented are results of the statistics study which characterize the development of the modern banking system. It is ascertained that within asymmetry of information the transparency level is critical in assessing financial stability of banks which is still given poor consideration in our country. The authors believe that the use of the suggested tool for determining banksâ€™ transparency level in bankâ€™s operation will help impartially assess its transparency level, will promote the development of channels of information disclosure to external users. It is rationalized that effective banking activity in Ukraine can ensure the recovery of the financial sector and restore the growth rates of the real sector of the countryâ€™s economy. The authorsâ€™ concept of increasing banksâ€™ transparency in assessing financial stability of the Ukrainian banking system proves that it is the basic condition for maintaining bankâ€™s favorable potential and effective performance. For the first time systematized are the characteristic features of transparency when analysing the transparency of the banking system as a whole. Distinguished is the expediency of using a certain set of tools and information disclosure channels in implementing the mechanism of transparency at different levels of the banking system. A conclusion is made that it is necessary to increase the transparency of banks in assessing the financial stability of the banking system of Ukraine, namely: ensuring information transparency of the bank will help to increase the confidence of market participants and provide an opportunity for the bank to expand its resource base, increase income and profits.Â Â Â

Published: July 2024

To confirm the author's hypothesis about what the negative impact on the state of the national economy have not so much economic or political factors, but latent character factors. The influence of latent factors on macroeconomic processes is considered. Many factors influence the state of the national economy of Ukraine, where it is possible to consider an extended reproduction of shadow financial relations in the country. The main issue of shadowing the financial cash-flows lies in use of financial institutions, especially banks, insurance companies, stock brokers, credit groups to inefficiently withdraw funds, to evade taxes and to avoid legalization of profit, earned through crime. The terms of management put forward the objective necessity of the study of the latent factors that hinder the economic convergence of Ukraine with the standards of the leading developed countries, particularly in Europe. The research of scientific publications on problems, materials s of rating organizations and statistics data has allowed the authors to suggest synergetic idea of combining the processes of state management and social self-organization optimally, the necessity to involve scientists and society to develop implement and monitor methods of anti-corruption, as the main threat to economic security and further development of Ukraineâ€™s national economy.To achieve the purpose the complex of general scientific and special methods was used: abstract logical, monographic, induction and deduction, theoretical generalization and systematization â€“ to determine and generalize theoretical and methodological foundations of latent management as a systemic factor of shadow economy; the semantic method was to define the terms; dynamic methods and comparative analysis, Pareto, expert assessments were used to confirmation of the dominant negative influence of latent factors on the national economy.Forming the conceptual methods of mitigation of the impact of destructive latent management in the shadow sector on the national economy of Ukraine.Forming the perception about the influence of latent management as a destructive factor on the stability of existence of negative factors in the national economy of Ukraine, that is a barrier of economic convergence to the EU.Â Â

Published: July 2024

The effects of corrosion behavior and interfacial contact resistance (ICR) of sputtered chromium carbonitride (CrCN) on SUS 316L are investigated. The corrosion behavior of CrCN coatings as potential bipolar plates in proton exchange membrane fuel cells (PEMFCs) are studied by potentiodynamic tests in 0.5 M sulfuric acid (H2SO4) with a scan rate of 1 mV/S. The ICR values are measured to evaluate electrical conductivity. The surface topography and roughness are monitored by atomic force microscopy (AFM) to investigate the surface features of CrCN coatings that correspond to the X-ray powder diffraction (XRD) analysis. The diffraction peak of CrCN has a current density (Icorr) of 0.1 ÂµA cmâ€’2 and ICR of 2.12 mÎ© cmÂ² at 80 ÂºC after the coated 316L is polarized. The formed metal nitrides and carbides possess prominent physical and chemical properties, such as superconductivity, high hardness, high melting points, high electrical conductivity and good corrosion resistance. Favorable factors are observed in CrCN of Sample C with 150 W and 80 min deposition that resists corrosion either at the anode or cathode side in the PEMFC. Coating materials using CrCN are proposed to improved bipolar plates, to achieve the single cell performance in PEMFCs.Â Â

Published: July 2024

This paper presents the modification of an existing front inner bumper of a passenger car.Â The manufactured bumper was captured by using three-dimensional scanner ATOS-GOM in order to obtain the CAD cloud geometrical data. Impact analysis was the conducted by employing dynamic explicit time stepping algorithm software IMPACT. The software was firstly benchmarked with known experimental results of beam under low velocity impact. The simulation and experimental results of the deflected beam were relatively comparable with variation from 1.6 to 9.5%. Two impact simulations were then performed on the real bumper; 40 percent offset collision and full frontal collision. The collisions were tried in different velocity of 48 km/h, 64 km/h and 110 km/h. The results were utilized as the benchmarking platform to enhance the bumper performance. Two alternative design modification were tried. Both design A and B exhibit significant increase of internal energy adsorbed. Even with the increase of energy being adsorbed by both the designs, still design B exhibits superiority in every way possible.Â
