Dynamic constraint and objective generation approach for real-time train rescheduling model under human-computer interaction

Real-time train rescheduling plays a vital role in railway transportation as it is crucial for maintaining punctuality and reliability in rail operations. In this paper, we propose a rescheduling model that incorporates constraints and objectives generated through human-computer interaction. This approach ensures that the model is aligned with practical requirements and daily operational tasks while facilitating iterative train rescheduling. The dispatcher’s empirical knowledge is integrated into the train rescheduling process using a human-computer interaction framework. We introduce six interfaces to dynamically construct constraints and objectives that capture human intentions. By summarizing rescheduling rules, we devise a rule-based conflict detection-resolution heuristic algorithm to effectively solve the formulated model. A series of numerical experiments are presented, demonstrating strong performance across the entire system. Furthermore, the flexibility of rescheduling is enhanced through secondary analysis-driven solutions derived from the outcomes of human-computer interactions in the previous step. This proposed interaction method complements existing literature on rescheduling methods involving human-computer interactions. It serves as a tool to aid dispatchers in identifying more feasible solutions in accordance with their empirical rescheduling strategies.

Embedding Kalker's variational theory into railway vehicle system dynamics and its efficiency improvement

The wheel–rail contact plays a vital role in railway transportation, hence an accurate wheel–rail contact model is the key to the simulation of railway vehicle dynamics. Though Kalker's variational theory is the canon, fewer works try to embed it into railway vehicle dynamics, mainly due to the computational efficiency problem and the complex wheel–rail geometry processing. This paper proposes a wheel–rail geometry processing method to embed KVT into railway vehicle multi-body dynamics based on the trajectory coordinate formulation, which conveniently introduces the wheel–rail contact surface pair for tracking the potential contact areas. After this prior detection, coarse detection is performed to narrow the range of penetrated elements. Multiple contact patches can also be identified based on the connection topology of discrete elements of wheel–rail surfaces. Thus, Kalker's variational theory can be used on each separate patch for local contact evaluation. An initial prediction method for the contact status is embedded in the multi-body dynamics simulation to accelerate the solution of Kalker's variational problem, in which the tractions with contact divisions obtained from the neighbouring system states are selected as the iterative initial value. The importance of predicting the contact tractions and demarcation for the convergence of the iteration is revealed. The proposed method is fully demonstrated by the Manchester contact benchmark and simulations of a railway vehicle passing through a curved track. As an advantage of embedding Kalker's variational theory, the precise traction pattern is obtained simultaneously along with the vehicle dynamics simulation, and the influencing mechanism of the track geometry on the vehicle system is analysed. The improvement of solution efficiency is also verified in simulations.

Insulating joints as a destabilizing factor in the operation of the track circuit

The role of railway transport in the modern economy is highlighted in the article. Directions for improving automation and telemechanics devices have been determined: the creation and implementation of modern devices for monitoring track occupancy of a new type, as well as increasing the reliability of track devices to a large extent, and putting into operation systems for interval regulation of train traffic. The importance of such an element of the railway infrastructure as a rail circuit is also determined. The authors of the work revealed the function of track circuits. In addition to this, the article presents an information diagram of the search for failures in an extensive rail circuit of electrical centralization. The concept of a decision device is disclosed. Possible expressions of the Bayes criterion are also considered. A priori probabilities of finding rail lines are singled out. As a result, a decision rule is revealed that leads to the minimization of the average damage.

Role of Railway Transport in Green Deal 2050 Challenge – Situation in the Czech Republic

Motivating people to switch to public transport from using their own car is one of the most important parts on the way to accomplishing the Green Deal 2050 challenge. In the Czech Republic, where the number of passengers was rapidly rising in the pre-pandemic time, individual car transport still offers many more travel benefits than railway lines for most long-distance relations. How to strategically develop the railway infrastructure? Will the planned high-speed railways really be the appropriate solution to this problem in time? Will they satisfy all the different requirements of passengers who are potentially able to switch from car to train?

Advancing the development of railway transport with the help of digital technologies

Background: The object of the study is regional and global cargo transportation. In order for cargo transportation to link the national economy into a single whole, and also allow it to realize its export opportunities, the level of organization of railway transport should be significantly higher than that of other market participants (primarily shippers and consignees).
 Aim: to study the prospects for increasing the role of railway transport with the help of digital technologies.
 Methods: To model the role of railway transport at the national and global levels, the article uses the concept of general organizational science by A. A. Bogdanov (Tectology). The Theory of Inventive Problem Solving (TRIZ) is used to model the role of railway transport at the micro level.
 Results: Railway transport is considered as a system consisting of subsystems: "working body", "transmission", "engine" and "computer". Each of these subsystems corresponds to separate divisions of railway transport. Digitalization involves the transfer from a person to automated systems, first of all, the functions of such a subsystem as a "working body", which functions according to the same algorithm and, therefore, is extremely routine. This simplifies and makes more predictable the production activities of the relevant departments of railway transport, which in turn creates the opportunity to increase the complexity of other subsystems.
 Conclusion: Railway transport was originally created as a complex macro system based on the most advanced technologies and significantly ahead of other industries in its development. Because of this, he was able to dramatically increase the level of complexity of the territories that he reached. However, today railway transport is experiencing increasing competition from other modes of transport, and therefore qualitatively new measures are required from railway transport to ensure advanced development. To do this, it is proposed to apply digitalization to the process of physical movement of goods as a whole: from fixing the need for transportation from shippers to delivering goods directly to the production sites of consignees. In this case, the main competitive advantage of railway transport becomes the "computer".

Models of Organisation of Combined (Mixed-Mode) Passenger Transportation

The article examines business models for mixedmode (combined) passenger transportation and development of combined passenger transportation as a factor in the growth of capacity of the railway passenger transportation market. The crisis in the transport services market, caused by non-economic factors (COVID‑19 pandemic), is characterized by a classic combination of supply shocks and demand shocks for passenger transportation, which increases relevance of the problem of searching ways to rise the volume of passenger traffic, in particular, by rail, demand for services provided to the public using railway assets.The current approach to increasing the demand for railway passenger transportation by developing the railway route network, improving the equipment of railway stations and the quality of service, expanding the range of services offered, promoting everything that encourages the consumption of services by a larger number of customers, will remain important. Nevertheless, this approach should be critically considered and supplemented in the light of new economic trends motivated by digital technology. That is especially important today, when, in conditions of resource constraints, a strategic organisational solution is needed aimed at scaling a business, achieving an optimal «balance» of costs, quality, competencies, flexibility and customer focus.The organisation of combined passenger transportation involves active «horizontal» interaction of various transport organisations, both among themselves and with different cohorts of passengers with their own consumer preferences and income restrictions. Therefore, the transition from linear business processes built «vertically» to horizontal business processes that offer specialised packages of services through a «single window» system according to uniform standards based on digital technologies is relevant.The article proposes models for organising network interaction of participants in the passenger transportation market based on digital technologies to ensure «seamless» mobility of the population with the consolidating role of railway transport. Specific models for organising combined railway transportation should be based on a specific business model, the choice of which is determined by a strategic decision of the company.

Magistral transport as a key link in the Russian transport system

The subject of the study is the study of the characteristics of cargo flows on the two largest types of main transport (sea and rail) in the world and in Russia. The relevance of the research topic is associated with the expansion of the functional capabilities of main transport, as well as with the complexity and lengthening of logistics supply chains in global commodity exchange, and the intensification of international trade. Methods applied logistics, general theory of systems, analytical, marketing, statistical, project methods, as well as materials of general access and official sites, own research. Researched railway and sea transport modes are characterized, their operational indicators are analyzed, the scale of cargo flows in the world and in Russia is estimated, as well as a brief description of the performance indicators of main modes of transport and the role of railway transport in the Russian economy is described. Russia has railway and marine types of main transport were studied. Taking into account the spatial and geographical location of our country, the importance and role of railway transport are manifested both in domestic transport and in international cross-border logistics, as well as in the organization of cargo transportation in the world’s commodity distribution networks. But along with this, there are huge areas in Russia where the railway network is very rare or absent. It is noted that the attractiveness and importance of rail transport for the carriage of goods due to such reasons as the orientation of the domestic economy on commodity exports (raw materials more profitable to haul trains) and underdevelopment of the road network.

Determination of the features and basic principles of finance of railway transport in conditions of energy conservation

The object of research is the finance of the railway industry in terms of energy conservation. Since the role of railway transport in social production is unquestionably significant, because until a certain product is delivered to the consumer, it is not completely manufactured, so to speak, and can’t be used by the consumer. An important role in the work of railway transport is played by its finances, without which the work of enterprises is impossible, especially in conditions of using energy-saving technologies.It is shown that the financial management of the transport industry in the context of energy conservation at the present stage of development of the railway industry and the country’s economy is one of the main areas of management activity. Financial management of transport enterprises is the process of coordinating all the determining components of the financial system to achieve the stable operation of transport enterprises and, no less important, its development. The content of such concepts as «financial management» and «finance of the railway industry enterprise» has been clarified based on a synthesis of various modern scientific approaches to the study of these categories and the identification of the main features for adaptation to energy saving conditions. So, let’s consider the finances of the railway transport company as the monetary system of the specified economic entity, that is, the totality of payments, receipts, distribution and use of funds in the process of its production and economic activity. Effective financial management of a railway company is an opportunity for organizational, financial and economic sustainability of a railway company in the context of energy conservation. At the same time, losses from compliance with the above conditions are minimized, thereby maximizing the economic added value of the enterprise during its operation and development. Consequently, the financial management of the transport industry company works by saving energy resources; it should use a management model that provides solutions to the interrelated tasks that arise with this method of managing.
