Risk assessment of innovative projects: development of forecasting models
(2021) Gorokhovatskyi, Volodymyr; Sergienko, Olena; Sosnov, Igor; Tatar, Maryna; Shapran, Evgeniy
The purpose of this article is development a systematic dynamic complex model of generation and risk assessment of innovative project, on the bases of which a scenario modeling of many risks influence arising at certain stages of project implementation in the target area. For article purpose realization, the paper proposes a complex toolkit for modeling the innovative projects risks in the direction of their impact on performance indicators in scenarios, which involves the implementation of the following stages of modeling: Stage 1. Collection and processing of project data; Stage 2. Evaluation of innovation project efficiency indicators; Stage 3. Formation and assessment of many risks of innovation project by components, nature and impact strength; Stage 4. Modeling of innovative project development scenarios. The implemented set of models makes possible to compare all components of efficiency and riskiness, which determine the integrated aggregate level of project risk by components of life cycle risks, target project risks and scenarios depending on environmental factors and managers propensity to take risks, and solves the problem of positioning the real indicators state of innovation project efficiency in a comparative dynamic context based on three-level assessment, due to structural elements of risks and identification of possible and promising deadlines and time horizons by stages of the project life cycle, critical paths and reserves which allow us to achieve the main goal of improving the innovative projects implementation efficiency.
Model Tools of Credit Risks Assessment of Agricultural Enterprises in International Trade
(2020) Nashchekina, O. N.; Sergienko, Olena; Sosnov, Igor; Tatar, Maryna; Shapran, Evgeniy
The paper aim is improving the methodological tools for agricultural enterprise's credit risks assessment and classification as participant of international trade market. The proposed approach differs from the existing approaches by complexity and systematicness, on the bases of usage of multilevel factor system of the borrower's assessment by local and aggregate components. The object of research is set of credit risks affecting crediting processes in agricultural sector of Ukrainian economy. The following economic and mathematical methods of scientific research were used: factor and comparative analysis (to highlight classification specific features of agricultural sector crediting), methodology of integrated rating (for rating of local components of risk), methods of factor analysis (to confirm the hypothesis of grouping of agricultural enterprises credit risks by components), hierarchical and iterative methods of cluster analysis (to distinguish agricultural enterprises classes by risk level). The proposed methodology is tested on a sample set of observations for 14 agricultural enterprises of Ukraine for 2018 year for the selected 38 credit risk indicators. On the bases of economic and mathematical tools for estimating and analyzing the aggregate system of agricultural enterprises credit risk indicators, namely the methodology of factor analysis, the hypothesis regarding the grouping and formation of agricultural enterprises credit risk classes has been improved. Five major systemic groups of external and internal risks which are specific to agrarian enterprises are identified: mortgage risks, system providing risks, system forming risks, natural and climatic risks, production risks. The obtained classes by risk level by the studied components on the basis of cluster analysis methods make possible to determine the set of critical and safe states in general and by local components and to choose effective behavior trajectory for agricultural enterprise creditworthiness increasing. The assessment results using proposed methodology laid in the bases of scenarios development of agricultural sector lending, make possible to develop a set of measures for strategic and tactical management of agricultural enterprise's creditworthiness and adjust their behavior in international markets.
Improvement of Adhesion of the Wheels of the Railway Carriage to the Rails by Means of Supply of the Scale and Magnetite Particles to the Contact Zone
(Allerton Press, Inc., 2018) Sosnov, Igor; Osenin, Yu. Yu.; Osenin, Yu. I.; Chesnokov, A. V.; Sergienko, O. V.
The article proposes a method to improve adhesion of the wheels to the rails of the railway carriage by means of supply of abrasive loose materials as an alternative to quartz sand to the zone of their contact: metal scale (Fe₃O₄ ) being the waste of rolling and forging, as well as the iron oxide—magnetite (FeO·Fe₂O₃) of the natural origin. The comparative assessment of efficiency of use of scale and magnetite was carried out in relation to quartz sand traditionally used for railway transport. The adhesion coefficient and wear intensity are used as comparison criteria.
Electromagnetic system for improving the adhesion of wheels to rails
(Silesian University of Technology, 2019) Osenin, Yuri Yu. ; Antoshkina, Lidiya; Sosnov, Igor; Shapran, Evgeniy; Chesnokov, Aleksei
The article describes the design of a system used for the improvement of the adhesion of locomotive wheels to rails; the principle of which is based on the electromagnetic feeding of the contact area with the bulk material that has magnetic properties and high hardness (iron scale Fe₃O₄ and magnetite FeO×Fe₂O₃). The experimental results of laboratory and bench tests confirming the effectiveness of the proposed system compared with the existing devices using quartz sand to improve the adhesion of wheels to rails are presented. It is concluded that the use of an electromagnetic system for improving the particle supply to the wheel/rail interface is promising.
Providing stable friction properties of disc brakes for railway vehicles
(The Silesian University of Technology, Wydawnictwo Politechniki Śląskiej Gliwice, 2017) Sosnov, Igor; Osenin, Yuri Yu.; Douma, Mansur Al-Makhdi; Sergienko, Oksana; Chesnokov, Aleksei
A new approach is developed to ensure the stability of the coefficient of friction at different braking modes for the entire speed range of braking high-speed ground transport. The new approach is a combination of friction materials with individual effort effects on the brake disc. A brake pad design and its performance are confirmed experimentally.
Providing the Stability of the Coefficient of Friction of a Vehicle Disk Brake under Extreme Operating Conditions
(Allerton Press, Inc., 2016) Sosnov, Igor; Osenin, Yuri Yu.; Osenin, Yuri I.; Douma, Mansur Al-Makhdi; Sergienko, Oksana; Chesnokov, Alexander
The authors propose a method of providing stability of the coefficient of friction of a disk brake. The method is based on the use of combination of friction materials in the force pattern of working elements of a disk brake. These friction materials interact with a brake disk and have individual level of loading. The article theoretically substantiates the possibility of the impact of the integral properties of a combination of friction materials involved in the force interaction on vehicle braking parameters. The reasonability of the proposed method is proved by the results of the experimental research. A brake-pad (lining) design has been developed to implement this method.

(Allerton Press, Inc., 2016) Sosnov, Igor; Osenin, Yuri Yu.; Sergienko, Oksana; Chesnokov, Alexander; Douma, Mansur Al-Makhdi; Osenin, Yuri I.
The paper presents the results of theoretical and experimental investigations in the effect of a partial heat energy removal in the friction contact zone upon the disc brake coefficient of friction during braking. A fluid cooling system for the disc brake friction elements has been proposed based on a recuperative liquid-pneumatic heat-exchange apparatus.
