Its most complete solution can be obtained if the problem is considered as multi-criteria. The article presents a formalized structure of criteria, allowing to optimize the interaction of objects of the logistics infrastructure of transport and warehouse services and freight road transportation. The choice of criteria for efficiency of the transport and logistics system (TLS) is based on effective indicators, which in turn are determined taking into account the indicators of the use of the means of production in certain conditions of the operating environment. The criteria system considered in the article is a decomposition of the hierarchy of TLS criteria that determine the organization of freight road transportation (FRT) and functioning of transport and storage complexes (TSC). The choice of performance criteria is based on the effective indicators of FRT and TSC, which in turn take into account the indicators of the use of means of production in the conditions of the environment of operation. Integration of FRT and TSC criteria into a single structure allows to solve multiple tasks. Keywords: transport and logistics system, road freight transportation, transport and warehouse complex, management, efficiency criteria, performance indicators, operating environment, indicators of the use of means of production.

Intelligent Transportation Systems (ITS) play a fundamental role in reducing congestion, reducing traffic accidents and improving road safety. Proper evaluation of the effectiveness of these systems is an urgent task in terms of improving the performance of the entire transport network, and the development of a set of evaluation indicators will make it possible to make managerial decisions on planning the development of intelligent transport systems. To test the hypotheses about the possibility of using indicators to assess the effectiveness of ITS, a one-sample t-test was used, during the analysis it was found that the proposed indicators «environmental friendliness and safety», «reliability of the transport network», «competitiveness of public transport» are suitable for assessing intelligent transport systems

The study is devoted to the process of evaluating the efficiency of the transport system in terms of urban mobility. The approach is based on the use of a system of performance indicators using neurocomputer technologies. Generalized models for obtaining a vector of performance indicators and an integral performance indicator in the form of computer neural networks are proposed. It is shown that to record the fact that the indicator values fall to the threshold and below, it is enough to use a neural network built on perceptron neurons. The multi-layered model for determining the integral indicator allows assessing the importance of individual indicators in the system of monitoring the efficiency of a given configuration of the transport system. An experimental study of twenty-five states of the transport system of various configurations in the cities of Poland and Ukraine was carried out. The key indicators of the system's efficiency are determined, namely, the energy efficiency indicator of the vehicle as a system element, the environmental indicator and the traffic safety indicator. Based on the results of the experimental study, a neural network structure is proposed for evaluating the energy efficiency of given configurations of the transport system. For the purpose of training and testing the obtained network, the procedure of adjusting the threshold value of the activation function and normalizing the values of the input parameters array of the transport system was used. The constructed network was implemented using Visual Studio 2019 using the C++ language. The network was adjusted to determine the energy efficiency estimate with a given accuracy by replacing the perceptron neuron with a regular one with a sigmoidal activation function. The random nature of the choice of the configuration and the initial values of the weighting factors made it possible to obtain a model with an accuracy of implementation on the control sample in the range from 90 to 98.7% at a learning rate of 0.1.

Full textAbstract:
Transport accident statistics and practical safety results indicate that technological solutions cannot ensure the viability (safety, sustainability, reliability and efficiency) of complex systems and structures without addressing human factors. This problem is especially acute for transport systems as highly complex technological and social structures aimed at ensuring the efficiency and safety of an entire sphere of human life. In transportation systems and technologies, the human factor plays a critical role. The successful operation of transport systems requires consideration of the human factor at all levels – starting from the development, design and planning of systems and technologies, training and education to the involvement of society in decision-making processes. Therefore, it is essential to develop the concept of human factor management and analyze the main problems in transport systems associated with the human factor to improve the safety, reliability and efficiency of their functioning. The article is devoted to the analysis of the human factor problem in transport systems and the search for solutions to manage it. The purpose of the article is to analyze the main problems in transport systems associated with the human factor and to develop the concept of human factor management for further search for solutions to improve the safety and reliability of transport systems. A set of instruments was proposed in the study to achieve the goal and solve the set tasks. Problems connected to the human factor in transport systems were analyzed. The main directions for solving problems with the influence of the human factor on the safety of transport systems were systematized. The main principles, models and ways of developing the concept of managing the human factor problem in complex systems, including transport, were outlined. A systematization of the risk management strategy was proposed. A matrix for the relationship between risk management strategies and approaches to managing the safety of complex systems was proposed. A new look at the principle of adaptive ergonomics as an implementation of the tolerance strategy was proposed, and applying the principle of adaptive ergonomics to transport systems was considered. The main motivation of the work is to attract the attention of the scientific and educational community to the problem of human factor and the need to use the concept of human factor management in the educational process to improve the general safety culture in society.

The intellectualization of water transport is accompanied by an expansion of the landscape of threats to transport security, caused by the characteristics and weaknesses of the technologies being introduced, which are the convergence of information and telecommunication technologies, automated and automatic control technologies and artificial intelligence. The peculiarity of these technologies is working with large volumes of information. Violation of the security of information processed in intelligent systems of water transport (illegal access, modification, deletion and similar unauthorized influence) causes a violation of transport security and, as a consequence, the security of critical information infrastructure and the country’s critical infrastructure, national security. Convergent technologies used in intelligent transport systems are characterized by multiple and poorly formalized manifestations of the consequences of threats. The article presents a model for assessing the risks of information security of intelligent water transport systems, based on the methods of the theory of fuzzy sets and fuzzy logic, the use of which makes it possible to take into account the above-mentioned features of the technologies being implemented. The hierarchical structure of the model and the use of fuzzy set theory and fuzzy logic methods make it possible to adapt the model to various risk criteria, types of input data and the level of detail of risk analysis. For the presented model, a methodology for assessing information security risks has been developed and an example of risk calculation is given. The developed model and methodology are intended to build an information security risk management system for autonomous shipping, implementing technologies of hybrid (augmented, extended) intelligence, providing for the use of artificial intelligence controlled by people.

Full textAbstract:
Gear pumps are widely used in transport machines not only in hydraulic drive systems, but also in lubrication and fuel systems. A positive displacement pump converts mechanical energy into pressure energy stored in the liquid, which it transports to the hydraulic cylinder or motor. The efficiency of this process depends on the efficiency of the system components, including the efficiency of the pump, which depends on the amount of internal leakage through the gaps between the high and low pressure sides. The larger the gaps, the lower the volumetric efficiency. This article presents an investigations of impact of pump deformations on circumferential gap height. The article presents a three-dimensional model of an external gear pump using Finite Element Method (FEM) during operating conditions. The model reflects pumping operation at discharge pressures up to 32 MPa and it was validated against strain measurements of pump casing. The simulation results indicate that the pump casing becomes deformed due to pressure, causing a significant increase in the height of the circumferential gap. The increase of the discharge pressure from 8 to 32 MPa causes more than twofold local increase in the height of the circumferential gap. The obtained results indicate that for the correct modelling of the flow generated by gear pumps, it is necessary to consider the change in the size of the gaps resulting from the deformation of the pump.

Full textAbstract:
The article examines the role and efficiency of air transport within integrated logistics systems, emphasizing its strategic function in ensuring speed, reliability, and global connectivity in multimodal supply chains. Air transport is positioned as a critical component that facilitates rapid movement of time-sensitive and high-value goods, particularly in sectors such as pharmaceuticals, electronics, and e-commerce. The article identifies and analyses the core advantages of air freight, including short delivery times, high schedule predictability, secure handling, and the ability to serve geographically isolated regions. In addition to highlighting these strengths, the study also outlines the main limitations of air transport, such as high operational costs, limited cargo capacity, infrastructure dependency, environmental concerns, and strict regulatory requirements. Special attention in the article is given to the integration of digital technologies and the application of the AeroSync model as an innovative conceptual framework aimed at improving operational efficiency and supporting decision-making in air logistics. The model systematizes key components of the logistics process–input factors, constraints, integration mechanisms, and performance outcomes–and serves as a scalable and versatile tool for logistics companies seeking to optimize multimodal transportation involving air freight. The study includes an in-depth analysis of real-world implementation practices by leading international logistics firms such as SEKO Logistics, Omni Logistics, Noatum Logistics, and Logistics Plus. These case studies illustrate the effectiveness of combining air transport with digital platforms, analytical tools, and strategic planning to achieve higher levels of control, adaptability, and competitiveness in a global logistics environment. The findings confirm that air transport, despite its challenges, remains indispensable in modern global logistics and that its performance can be significantly enhanced through structured integration models and smart technology adoption.

Full textAbstract:
The article develops a model for evaluating the effectiveness of a complex transport system based on the use of an information criterion to assess the effectiveness of actions to restructure it. The measure of the amount of information entered into a logistics transport complex system to eliminate the uncertainty of behavior, both of the system itself and of individual events, is taken as a parameter of the information criterion. At the same time, the developed model ensures the unity of efficiency meters in logistics transport systems, since it is based on methods for predicting the value of the influence of factor space on the process under study in order to increase the efficiency of the system as a whole. The development of an information criterion model makes it possible to proceed to the construction of algorithms for determining the optimal trajectory of a cargo shipment in an integrated logistics transport network.

In this article methodological subjects of activities efficiency research of the transport companies as well as other complex systems are analyzed. Methodically it is the most important to select estimation indexes of efficiency of searching object activities. After the system of indexes is formed, it is determined that it is more useful to use the system of technical economic indexes in order to estimate the level of efficiency of the activities of transport companies. It is so, because none of the separate indexes individually is able comprehensively to reflect the activities of transport systems or separate companies. Using the proposed method it is possible to research the great amount of objects according to numerous indexes. The main task is to form conditionally monolithic groups from the totality of objects. The level of activities of the objects in these groups should be similar. It would be possible to solve this task with the help of the image identification theory. The essence of this theory is to used necessary algorithm for the identification of searching objects signs. On this basis each object is reckoned in a certain monolithic objects group. Next step is the use of classification algorithms, which enable to classify the whole of searching objects. In this article you would fmd two main stages of classification problem solution. In the first stage the expansion of the objects into monolithic groups according to one of the indexes goes. The quality of this stage depends on the amount of the groups and on the selection of a concrete index. In the second stage the final objects expansion into monolithic groups according to the whole of selected technicaleconomic level indexes goes. Here is the manifold classification of the objects. Its results enable to determine the efficiency level of transport systems activities as well as to improve the quality of planning transport company's activities.

The problems of storage and supplying the energy, together with reducing energy intensity for transport, are now crucial for developing sustainable and reliable transport systems. The energy network must be gradually adapted to new loads and power consumption patterns, especially in railways. The article aims to develop the simulation model to investigate the energy storage systems in its use in the electric transport infrastructure. The authors review selected technical solutions for electric energy storage in transport. The theoretical aspects of energy exchange in the energy storage systems were presented as a base for a continuous simulation model of electric transport power supply. In the non-periodic random voltage input applied to the storage unit, it is pro-posed to use the calculation method based on the Duamel integral to analyze its charge-discharge processes. The resistance functions were applied to analyze the traction power supply mode with variable in time and space by active loads. The simulation showed that the direct connection of the unit to the traction network significantly reduces the traction energy consumption.

With the acceleration of globalization processes and increased international cooperation, freight transport routes are expanding, which requires new solutions for the most efficient use of various modes of transport. One of the most important factors that may improve the efficiency of the interoperability of different transport modes is information exchange allowing to plan transport flows in advance, exploiting benefits of the maritime and rail transport and minimizing its disadvantages. Precise information allows to find the most efficient mode of transport for the freight transportation chain. Precise information is necessary for effective management of information flows to ensure interoperability between the transport modes. This article analyses the specificity of railway and maritime transport modes, hence research questionnaire of Lithuanian transport companies is performed to present the results to show the most significant elements of railway and maritime transport interoperability. The completed expert evaluation enabled to prioritize the sequence of elements to ensure the efficient interoperability between rail and maritime transport.

Considering the significant role of integration processes in one of the key elements of the country's transport support – the organization of loading and unloading operations for enhancing transportation efficiency – the authors conducted an in-depth analysis of scientific publications by both Ukrainian and foreign researchers. Rapid changes occurring in all spheres of economic activity, along with the insufficient responsiveness within transport systems, highlight the importance of adaptation processes, especially for maintaining competitiveness and ensuring the efficient functioning of transport and logistics infrastructures. To improve integration, it is necessary to implement unified software systems that ensure the coordinated operation of both production and transport systems, develop networks for effective interaction among process participants, expand shared infrastructure to facilitate logistics operations, and integrate different types of systems and technologies that form essential components of production and transport processes. Based on existing issues related to the insufficient automation of transport technological processes within production systems, the authors have studied, analyzed, and presented the impact of the organization and technology of loading and unloading operations on production systems. The execution of loading and unloading operations directly affects the economic efficiency of transport systems, mainly through a logistics-based approach, improving the mechanization and automation of cargo processes, which accelerates the execution of these operations. The suitability and efficiency of using different types of transport vehicles depend on technological schemes of mechanized cargo handling, which are developed according to various transshipment options while considering specific production systems. The productivity of mechanisms and the time required for loading and unloading operations directly impact vehicle downtime at loading and unloading points and, consequently, the efficiency of transport operations on routes. Thus, loading and unloading operations are a crucial element of the transport production system, directly influencing its productivity and efficiency. Thanks to such innovations, transport production systems become more flexible, faster, and better able to respond effectively to market changes and customer demands.

We present a nonparametric comparative efficiency analysis of urban public transport systems (UPTS) in Shanghai (2004-2012). The UPTS include urban public bus transit system (UPBTS) and urban public rail transit system (UPRTS). We apply data envelopment analysis (DEA) to assess the technical, pure technical and scale efficiencies of UPBTS and UPRTS over years. We find the performance of UPBTS and UPRTS are good in general but still have a potential scope for improvement. We also quantitatively analyze the reasons for inefficiency of them in some years and provide potential improvements for inefficient units. Moreover, we observe the efficiency of UPBTS is better despite a good development trend in the efficiency of the UPRTS. We demonstrate the UPRTS during the period 2006-2011 works on decreasing returns to scale (DRS), which indicates the authorities should adjust the UPRTS structure and improve the operational services without blindly expanding the levels of inputs. Our work may help in evaluating the possible enhancement of the operations of the UPTS.

Abstract The quantity of management systems standards (MSSs) is increasing every year. Standards are significantly associated with common requirements and differences for many providers of services as well as for manufactures. The drinking water supply management system is certainly one of the important services. The aim of this article is to introduce a basic application of management system (MS) using visual management. The standard applied in a model, defined as a complex solitaire or “singlet”, is the Water Efficiency Management Systems (WEMS) standard. Visualised model is built by creating clusters using a software program designated for Small World Networks. This phase is preceded by the compilation of Excel spreadsheets, where requirements are divided into common and specific ones. The resulting cluster of selected areas includes the context of organizations that provide services, considering the common and specific requirements of interesting parties, managing their leadership, planning, support, operation, performance evaluation and improvement. It could be very useful to extend the cluster by another standard depending on the needs of the drinking water supplier and the transport piping systems at the site. This approach to management systems intensively clarifies managerial decision-making processes related to the implementation of the WEMS.

Intelligent Transport Systems work with information and control technologies which provide the core of ITS functions. Some of these technologies, like loop detectors, are well known to transportation professionals. However, there are a number of less familiar technologies and system concepts that are the key to ITS functions. The technical core of ITS is information and control technologies, but human factors are also vitally important, and potentially very complex. This paper introduces the main ITS enabling technologies and explains why transport professionals should involve human factor experts at an early stage of design of ITS equipment and facilities.

Nowadays, we face many problems in the field of transport. The application of intelligent transport systems should improve problems related to congestion management, road safety, access to data in the transport environment, and environmental protection. The paper presents two concepts that are key to the improvement and development of the transport sector. The development and application of automatic vehicle location since the 1960s has led to an improvement in the efficiency of transport companies’ operations and the quality of their services. This technology has led to improved efficiency of the transport service, better utilisation of resources and improved quality of service. However, the most modern concept that initiates the improvement of existing solutions and encourages the development of new solutions in the field of transport is the IoT (Internet of Things) concept. In freight transport, the application of IoT technology enables cost management, reduction of CO2 emissions and avoidance of congestion through the use of alternative routes.

This article discusses the use of systems analysis to study the problems of intelligent transport systems. The main problems of transport systems are identified and the main functions of intelligent transport systems are given. The object of research is intelligent transport systems. The purpose of the study – to analyze the feasibility of using methods of systems analysis in the study of problems of intelligent transport systems. The main advantage of intelligent transport systems is the simulation of various events and forecasting of dangerous situations. These systems are an important component of a systematic approach to improving the efficiency of the country's transport system.

Full textAbstract:
The 2030 Agenda states that sustainable transport systems, as well as other associated energy systems and policies, would create a strong economic foundation for all countries. In this regard, countries need to pay more attention to their transport systems. This has been accomplished through a great deal of work and policies that they can enact, such as improving fuel efficiency and government support. Therefore, this study attempts to compare the impact of a 10% increase in government subsidies and a 5% increase in improvement in fuel efficiency to the transport subsectors in Malaysia using a computable general equilibrium model (CGE). Results suggest that fuel efficiency improvement is an effective policy in increasing economic growth, exports, investment, and household consumption for the entire economy. While both policies increase output, employment, investment, and household use across the transport subsectors, except water transport, the magnitude of the impacts is greater for improving fuel efficiency policy. Improving fuel efficiency, despite the reduction in energy consumption in the land and water transportation subsectors, has led to a rebound in the air and other transport subsectors. However, increasing government subsidies to transport subsectors increases energy consumption and CO2 emissions in these subsectors. The outcomes of this policy can be used for the future of sustainable development in Malaysian transportation systems.

Full textAbstract:
The article reviews the history of invention of heat pumps, as well as the physical processes occurring during their operation. The main attention is paid to the efficiency of thermal energy utilization for space heating, heating of process water in the cold season and air conditioning in the warm season. In particular, the article considers modern systems based on heat pumps and the need to modernize rolling stock and buildings subordinated to Ukrzaliznytsia.Heat pumps are devices that allow the efficient transfer of heat from the environment (air, water or ground) into a room, which makes them highly demanded for heating and air conditioning. The benefits of heat pumps are obvious, as they can significantly reduce energy consumption compared to traditional heating methods such as gas boilers or electric heaters. In contrast, a heat pump can utilize the environment as a source of energy, converting it into heat with high efficiency. Heat pumps can significantly reduce running costs as their coefficient of energy conversion (COP) can exceed 4, meaning that it takes less energy to generate one kilowatt of heat from a heat pump than a traditional electric heater or boiler. Thus, switching to such systems is cost-effective and allows for a more stable and efficient supply of heat and hot water in buildings and facilities.In addition, the article addresses the important issue of how the use of outdated electrical and boiler equipment incurs significant maintenance and operating costs and negatively affects energy efficiency. Unlike traditional systems, heat pumps can significantly reduce these costs by providing a higher degree of energy conversion and minimizing energy use losses.Thus, the transition to modern systems based on heat pumps not only helps to reduce energy costs, but also meets environmental requirements by reducing emissions of carbon dioxide and other pollutants.

Full textAbstract:
The optimization of maintenance intervals is crucial for enhancing efficiency, sustainability, and cost-effectiveness in transport operations. This paper presents a method for optimizing maintenance intervals for vehicles in various modes of transport, focusing on minimizing downtime due to repairs and maintenance. By integrating advanced technologies like artificial intelligence (AI) and the Internet of Things (IoT), maintenance intervals are dynamically adjusted using real-time data, resulting in better resource utilization and reduced operational costs. The key findings of this research indicate significant reductions in downtime and maintenance costs, leading to improved efficiency and sustainability across transport modes. Although the case study is based on railway vehicles, the approach is applicable to road, maritime, and air transport as well. By leveraging optimization algorithms, such as machine learning, this solution predicts optimal maintenance timing, thereby reducing resource consumption and improving operational efficiency. The case study on pantograph maintenance demonstrates significant financial savings and reduced waste. This research highlights the benefits of maintenance optimization for sustainability and efficiency across the entire transport sector.

More and more attention become to Transport Company’s functioning efficiency due to growing of goods’ nomenclature and specific requirements for their service. Existing scientific and practical approaches to managing of transportation process consider separate service of each contract individually. Up-today requirements for transportation services complicate such evaluation. These requirements primarily include transportation frequency and volumes variation in each logistics system due to seasonal consumption of material flows. Different seasonality leads to irrational use of vehicles and decrees of their efficiency. All this gives rise to the mechanism of compatible transportation service of numerous logistics systems and their material flows by any enterprise. The paper consist of next sections the analysis of scientific framework and methods on the transportation services, fleet estimation, efficiency evaluations, analysis of requirements of transportation services; Mechanism of joint transportation services; Modelling of transportation services in logistics systems, where joint efficiency estimation of transportation functioning and logistics system and conclusions. The proposed methods and tools in the complex allow to identify and evaluate the effectiveness of the joint motor transport service of logistic systems by own and hired vehicles compared to the separate on the basis of performance indicators, which vary depending on the technological parameters: transport distances, runway usage factor, cargo class, load capacity of motor vehicles . The offered approach will reveal: regularities of change of indicators of efficiency of variants of the joint motor transport service between the traditional approach (a separate calculation of efficiency for each logistics system) and the proposed (calculation of compatible services), which allows to determine the equivalent cost of transport services during motor transport maintenance of material flows. The calculations confirm the effect of use compared to the separate combined transportation of material flows, which will be shown in reducing the required amount of vehicles by 31,8% and increasing efficiency from 5% to 60%, depending on the initial values of the transportation services parameters. The results of the project can be used in the formation of a freight vehicle fleet of any enterprise that is faced with the issue of hiring transport or have its own, PL providers, transport companies, and others.

Abstract The problem of ensuring the reliability of heterogeneous transport systems is extremely multifaceted and covers all stages of development - from design to operation. To increase efficiency, there is a need to harmonize the processes taking place in heterogeneous systems within the framework of single transport communication. The lack of appropriate theoretical justification leads in practice to the emergence of insufficiently substantiated decisions, because of which subsequent efforts made to eliminate the discovered shortcomings are, as a rule, costly and ineffective. Assessment of the system of integrated regulation of the transport system, from the point of view of its sustainability, is an indispensable condition for its operational efficiency and reliability. The efficiency of transport processes assumes that the effective functioning of local transport systems is ensured by the level of interaction between participants in the transport process, modes of transport that create positive dynamics of transit freight turnover. The paper substantiates the need for complex interaction in the management of the regional transport system, considering the interaction of adjacent modes of transport in a single information space. The method describes in detail the solution of forecasting and coordination problems in maritime transport systems, harmonization of the interests of heterogeneous transport in solving forecasting and control problems.

The modern development of cities is accompanied by a constant increase in the volume of traffic flows, which necessitates the improvement of transport logistics. An essential aspect of enhancing the quality of life, ensuring mobility, and reducing environmental pollution is the economic stability and efficiency of the city's transport system. Urban transport logistics is a multi-component system that includes planning, coordination, and management of all types of transport movement, optimization of infrastructure, and integration of innovative technologies. The study of modern approaches to assessing the efficiency of transport systems, considering their role in ensuring population mobility, economic development, and environmental sustainability, provides an opportunity to develop and implement methodological foundations for evaluating the efficiency of this system. This is particularly relevant in the context of rapid urbanization and global trends toward sustainable urban development. It has been established that the efficiency of urban transport logistics is influenced by specific factors, including the accessibility of infrastructure, the reliability of transport services, the rational use of transport resources, the system's ability to adapt to changes in the socio-economic environment, and the degree of integration of modern technologies.

As it is with every activity, the transport network can be organized in many ways by using different technical means and technologies. Taking certain management decisions is connected with the choice of one of the many possible options for realization of the transportation process. This is done with the help of one or a few indicators which serve as a criterion of efficiency, e.g. exploitation costs, profit, safety, time, etc. The research of the transport objects functioning and the optimization of their parameters is a very complicated task in most of the cases. In such cases the solutions of the problems which concern us are derived by the research and experimentation with a substitute (analogue) of the real object, specially designed for this purpose. This analogue is called a model and the process of its creation is called modelling.
