Dear Colleagues!
It is a great honour for us to present the Proceedings of the International Scientific and Practical Conference. We hope that you will find it useful, interesting and inspiring. The Proceedings contains the papers presented at the 8th International Scientific and Practical Conference: Transport, Education, Logistics And Engineering 2025, which was held at the Riga Aeronautical Institute (Riga, Latvia) on June 27–28, 2025. The conference was attended by representatives of many countries, including universities in Europe and Asia. The aim of the conference was to promote the exchange of advanced knowledge, innovative ideas and practical experience between scientists and specialists in the field of transport, logistics, engineering and education.

The conference is aimed at developing scientific and applied solutions to improve the efficiency of transport systems, develop sustainable logistics technologies and improve the methods for training specialists in the field of engineering and transport.
We hope that the conference will also serve as a stimulus for the emergence of innovative ideas and will promote the development of research links and partnerships between different institutions.

Developing a conceptual simulation model to analyze and improve traffic flows of the multimodal terminal "RIX" and decision-making for the formation of a new transport hub

The article explores the development of a simulation model as a decision support tool to aid the planning and development of a new multimodal transport hub at Riga International Airport (RIX), considering its integration with the Rail Baltica project. The study addresses the growing significance of multimodality in enhancing connectivity, passenger service quality, and infrastructure efficiency at major air transport hubs. The air transport system – comprising both demand-side (passengers, freight) and supply-side (airports, airlines, air traffic control) components - has long been affected by capacity constraints, congestion, and environmental issues. These challenges have persisted and, in some cases, intensified in the post-pandemic recovery period.
The aim of the study is to develop a conceptual simulation model that supports tactical decision-making for traffic flow optimization and infrastructure development at RIX. The research emphasizes complementary role of rail transport in multimodal integration, particularly its potential to extend air connectivity and enable seamless “door-to-door” travel chain. Best practices in multimodality at Helsinki and Singapore airports are reviewed. The current state of infrastructure and intermodal connectivity at RIX is analyzed, especially with reference to its future connection to the planned Rail Baltica line.
A holistic approach to service level analysis is applied, incorporating both terminal and regional access components. Given the complexity of such large-scale projects, modern model-based tools are essential for evaluating alternative scenarios and supporting planning decisions. The proposed conceptual simulation model provides a methodological framework for evaluating multimodal passenger flows and supports strategic decisions on hub development and infrastructure optimization.

A scientific examination of fleet air international’s management system

Konstantīns Savenkovs, Marija Ērgle — Wed, 19 Nov 2025 00:00:00 +0100

This study critically examines the evolution and effectiveness of Fleet Air International
(FAI), a commercial airline operator’s Management System within the context of contemporary
aviation safety regulation and operational demands. Emphasizing empirical
data collected from internal event reports in January 2025, this research analyzes
safety event trends, the management of organizational changes, audit outcomes, and
corrective action efficacy. The work situates FAI’s system against regulatory frameworks
including (EU) Regulation 965/2012 and Regulation 1321/2014. It also provides
evidence-based insights into risk assessment and mitigation strategies. The study
concludes with recommendations to enhance safety performance indicators and procedural
compliance, contributing to the broader field of aviation safety management.

Entropy-probabilistic model for controlling the human factor in the system of ensuring the airworthiness of aircraft and their components

Thu, 27 Nov 2025 00:00:00 +0100

The following issues are addressed in the paper:

A mathematical model for controlling human factors in the aircraft maintenance system is proposed, aimed at identifying priority tasks in maintaining airworthiness under conditions of limited resources.
The model is developed using factor analysis under uncertainty, employing the entropy ranking method. In this approach, non-conformances in the activities of technical personnel (violations and errors) are represented as a multidimensional random generalized factor that comprises several measurable specific factors. The task of the management system is to determine the entropy of the generalized factor based on these measurable components.
A functional diagram of the control system is developed based on a systems approach, considering it as a dynamic system that, at each moment, is described by a set of physical variables (parameters).
Based on statistical data on deviations in the activities of airline technical personnel collected over a 10-year period, entropy indicators were obtained for several logically grouped factors—generalized indicators characterizing the main areas of management activities related to the continuing airworthiness of aircraft.
The results make it possible to identify the main areas of preventive activities within the airline aimed at reducing the negative impact of human factors during aircraft maintenance, which is particularly important under conditions of limited resources.

Integration of academic and European Union aviation safety agency professional requirements

Ibrahims Arandas, Asnāte Venckava, Kirils Kļepackis — Fri, 28 Nov 2025 00:00:00 +0100

Over the next twenty years, the demand for qualified aviation personnel will need to be aligned with aircraft delivery plans. However, there is a growing tendency for students to prefer higher education over professional training, as an academic degree is often perceived as necessary for career advancement; yet professional training remains essential for becoming certified aviation personnel, such as licensed mechanics or avionics specialists. In this article, the authors propose a combined aviation training approach that enables trainees to obtain both a bachelor’s degree accredited by the national Ministry of Higher Education and the professional qualifications required by the European Union Aviation Safety Agency (EASA). The analysis of academic and professional programs presented by the authors can be used by the National Aviation Authority (NAA) to award examination credits, in accordance with EASA regulations, to graduates of higher education institutions.

Quality as the basis of flight safety

Igor Petukhov — Wed, 19 Nov 2025 00:00:00 +0100

The speed of technological development during the twentieth century was fully reflected in the aviation world, whether it was in terms of aircraft development systems for controlling air traffic or flight control systems. The fast pace of change continues today. Obviously, aircraft reliability and complexity have extremely improved for years, but nearly all accidents in civil aviation in recent memory have been the result of human error. At the early stage of aviation development the human factor (HF) share in total reasons of aviation accidents was 20 per cent, later it increased fourfold and currently it makes up about 80 per cent. It turned out, that the human in the system “Human – Aircraft” is the most unstable, the most unreliable and the weakest link: humans may make mistakes, moreover, the human has the right to be mistaken. No doubt, human errors preventing system must be worked out. The challenge is to make flying safer. It will be discussed below.
