Item Estimation of Management Effectiveness of Electricity Supply Enterprises in Emerging Economies(UIKTEN, 2021) Skibina, T.; Курбатова, Тетяна Олександрівна; Курбатова, Татьяна Александровна; Kurbatova, Tetiana Oleksandrivna; Сотник, Ірина Миколаївна; Сотник, Ирина Николаевна; Sotnyk, Iryna Mykolaivna; Теліженко, Олександр Михайлович; Телиженко, Александр Михайлович; Telizhenko, Oleksandr Mykhailovych; Сотник, Микола Іванович; Сотник, Николай Иванович; Sotnyk, Mykola Ivanovych; Hyrchenko, Y.The article gives an estimation of the management effectiveness of electricity supply enterprises in emerging economies on the example of enterprises of the northern and central regions of Ukraine. Estimation was conducted on the basis of the authors’ methodological approach that applies the number of indicators taken as a basis for the formation of the integrated indicator. The latter allows carrying out a comprehensive estimation of the management effectiveness system of the electricity supply enterprises. The obtained results show a low management effectiveness of the considered electricity supply enterprises. As a result, the conducted research identified the barriers that hinder the efficient development of electricity supply enterprises and outlined the main directions for reforming energy supply enterprises’ activity.Item Modeling of a Stress-Strain State of Detachable Connection in Details of Reinforced Composite Materials with Cea Method(Sciendo, 2020) Довгополов, Андрій Юрійович; Довгополов, Андрей Юрьевич; Dovhopolov, Andrii Yuriiovych; Некрасов, Сергій Сергійович; Некрасов, Сергей Сергеевич; Nekrasov, Serhii Serhiiovych; Жигилій, Дмитро Олексійович; Жигилий, Дмитрий Алексеевич; Zhyhylii, Dmytro Oleksiiovych; Савченко, Євген Миколайович; Савченко, Евгений Николаевич; Savchenko, Yevhen Mykolaiovych; Ступін, Борис Анатолійович; Ступин, Борис Анатольевич; Stupin, Borys AnatoliiovychIn order to study the strength of the proposed rope threaded joint for machine parts made of reinforced composite materials, a modeling of a stress-strain state was conducted using the software of finite-element analysis LS-DYNA. Stress-strain state modeling was conducted for a rope threaded joint, affecting on the main performance parameters considered to be p – thread pitch (p = 4 mm), and t – thread depth (t = 1 mm). The main thread parameters taken for the model were up to the metric thread М6 (ISO 724:1993) parameters.Item Enhancing Efficiency by Implementation of Integrated Management System in Order to Align Organisational Culture and Daily Practice(Sciendo, 2020) Залога, Вільям Олександрович; Залога, Вильям Александрович; Zaloha, Viliam Oleksandrovych; Дядюра, Костянтин Олександрович; Дядюра, Константин Александрович; Diadiura, Kostiantyn Oleksandrovych; Рибалка, Ірина Миколаївна; Рыбалка, Ирина Николаевна; Rybalka, Iryna Mykolaivna; Pandova, I.; Zaborowski, T.The main aim of presented article is present methodology how sophisticated products as compressor equipment can be considered and analyzed as a complex technical system which consists of jointly operating components – a set of hardware, software, operational staff and documented information. In process modeling, these components can be in different processes of inputs, outputs, mechanisms (resources) or management. Based on the regulatory requirements for each component of the system, a key indicator efficiency can be identified. This will allow to control the process and make appropriate decisions to improve the system. The application of the proposed methodology for the development and implementation of an integrated management system reduce the cost of resources and significantly improve the quality of the implementation of processes.
