To ensure the required quality, quantitative risk assessment models for the in-depth and express diagnostics system of helicopter gas turbine engines in a neural network environment are proposed. The assessment of diagnostic efficiency is based on the analysis of probable control risks by standard deviations, which distinguishes the proposed approach from the traditional one. Two diagnostic modes are considered: rapid diagnostics exemplified by vibration diagnostics, and in-depth diagnostics, including both vibration diagnostics and pyrometric control. These diagnostic methods make it possible to implement a remote monitoring system at aircraft repair facilities, which significantly reduces maintenance labor intensity. As a result, it was found that control risks depend not only on the metrological level of measuring instruments but also on a combination of the statistical nature of control agents in their system composition according to the following characteristics: statistical parameters of the controlled indicator, distribution laws, and values of uncertainty of measuring instruments, as well as the uncertainty of control standards (tolerances). In the modeling process, risks were assessed as a function of the ratio of uncertainties of measuring instruments to the uncertainty of the controlled parameter, with varying values of the standard (tolerance). This approach will allow, in practice, the creation of a more effective system for monitoring and collecting statistical information on the operational reliability of the Mi-8 helicopter engine, where the quality of control is predicted to a greater extent based on the metrological indicators of the measuring instruments and methods</p>2024-12-24T00:00:00+02:00Copyright (c) 2024 Kayrat Koshekov, Ildar Pirmanov, Saltanat Kenbeilova, Abay Koshekov, Rustam Togambayev, Beglan Toiganbayevhttps://journals.uran.ua/eejet/article/view/318451Identifying the influence of project delivery system (PDS) characteristics on green construction project performance2024-12-19T19:31:15+02:00I G A Istri Mas Pertiwimaspertiwi72@yahoo.co.idYulvi Zaikacicizaika@ub.ac.idKartika Puspa Negarakartika_puspa@ub.ac.idSolimun Solimunsolimun@ub.ac.idMochamad Agung WibowoAgung.wibowo@ft.undip.ac.id<p>This study examines the influence of Project Delivery System (PDS) features on green construction project performance by comparing Design-Bid-Build (DBB), Design-Build (DB), and Construction Management (CM) methods. The research problem is to analyze the influence of key characteristics (leadership, communication, mindset, teamwork, team chemistry, experience, competence) of the three PDS methods on achieving green construction project performance. The research objects were 109 respondents (team leader, vice president manager, project manager, site manager, site engineer, general superintendent, and supervisor) in five major cities in Indonesia. The results of the MANOVA analysis showed that leadership was the most influential factor in the three methods. CM excels in time, quality, and green building performance, DB excels in Occupational Health and Safety (OHS), and DBB excels in cost. Experience and competence are less influential factors, thus concluding that soft skills play a significant role in the successful implementation of green construction projects, providing valuable insights for industry practitioners and emphasizing the need to prioritize the development of leadership and interpersonal skills alongside technical expertise when implementing green construction projects through various PDS methods in Indonesia, which ultimately contributes to the advancement of sustainable construction practices in the rapidly growing building sector in the region. These findings provide insights for selecting optimal PDS methods in green construction projects</p>2024-12-24T00:00:00+02:00Copyright (c) 2024 I G A Istri Mas Pertiwi, Yulvi Zaika, Kartika Puspa Negara, Solimun Solimun, Mochamad Agung Wibowohttps://journals.uran.ua/eejet/article/view/316782Devising a method for building an educational project team based on the analysis of competency matrix2024-12-05T09:21:04+02:00Andrii Biloshchytskyibao1978@gmail.comMyroslava Gladkamiragladka@gmail.comOleksandr Kuchanskyikuchansky@knu.uaYurii Andrashkoyurii.andrashko@uzhnu.edu.uaAdil Faizullinadil.faizullin@astanait.edu.kz<p>The object of this study is the processes to form teams for educational projects. The issue addressed is the distribution of lecturers based on educational components, taking into account the complex set of functional requirements for the executors of specific educational projects. To successfully implement educational projects, it is proposed to build a reserve of personnel and form effective teams of performers who have the necessary competencies and experience in implementing international projects. A method for determining the individual competencies of executors of educational projects at institutions of higher education has been formalized. It is proposed to evaluate lecturers on the basis of their effectiveness in teaching educational components, which is measured by testing the level of assimilation of program results by students. As a result, a matrix of competences was constructed, containing the evaluations of performers, which helps the management of the institution to make decisions about the extension or termination of contracts with lecturers, as well as possible bonuses. A method for analyzing the matrix of competencies for the formation of an educational project team is to identify lecturers who have the necessary competencies to provide educational components. As a result of applying the method, a project team is formed, which is able to provide all the necessary competencies, taking into account the qualification requirements. The method helps determine the shortage of qualified personnel and the need for their development. The method was verified using an example of an educational project in Kazakhstan to form a team of lecturers that meets the qualification requirements of the educational program. The results show that even a minimum team of three people can provide all 16 competencies at an appropriate level, and the involvement of additional performers expands the possibilities of flexible distribution of responsibilities between them</p>2024-12-24T00:00:00+02:00Copyright (c) 2024 Andrii Biloshchytskyi, Myroslava Gladka, Oleksandr Kuchanskyi, Yurii Andrashko, Adil Faizullinhttps://journals.uran.ua/eejet/article/view/318533Implementation of knowledge distillation in developing a prediction model to know the performance of air transportation vocational education using machine learning2024-12-20T21:52:27+02:00Daniel D Romanidanieldromani@gmail.comDarmeli Nasutiondarmelinasution@gmail.comOkvi Nugrohookvinugroho@umsu.ac.id<p>The object of this research is the performance of air transportation vocational education. The problem in this research that must be solved is the complexity of the model in machine learning which requires a long processing time and requires high resources, so the knowledge transfer process in knowledge distillation must be carried out carefully so that the student model can capture and reproduce knowledge from the teacher's model. without loss of accuracy and problems such as Good Corporate Governance, Organizational Flexibility, and Strategic Change Management variables, which are interrelated and difficult to model accurately. The results obtained are in the form of a model that can predict vocational education performance by utilizing machine learning and knowledge distillation. The interpretation of this research is to apply the XGBoost machine learning algorithm and knowledge distillation. The characteristics and characteristics obtained are that the teacher model has the best performance in terms of loss, while the student model with distillation shows a significant reduction in loss compared to training without distillation. Thus, the distillation process is proven to help student models capture knowledge from teacher models, producing prediction accuracy of up to 90 % and being an efficient alternative in predicting the influence of main factors on the performance of air transportation vocational education. These findings are expected to provide a significant contribution to the development of more efficient and effective prediction models in the context of vocational education, especially in the field of air transportation</p>2024-12-24T00:00:00+02:00Copyright (c) 2024 Daniel D Romani, Darmeli Nasution, Okvi Nugroho
