Practical application of the idea of sustainable freight transport requires a significant development of the intermodal transport network in which rail transport plays an important role. It is indicated as an ecological, safe, fast and economic type of freight transport. However, an important matter conditioning its development and significance is the reliability of freight flows. In the literature research, there is a lack of comprehensive recognition of dependencies between the reliability of flows in intermodal network of rail transport and the disruptions and characteristics of the network. Therefore, the authors of the paper adopted an analysis of the impact of disruptions in freight flows in rail transport on the reliability of these flows. The paper assumes that the reliability of freight flows in rail transport is measured by the number of cancelled trains and an average delay time of trains. At the same time, it was also assumed that the impact of disruptions on the reliability of flows depends on the characteristics of the network itself. In conducted empirical research supported by regression analysis, the authors indicated relationships between the studied variables and identified gaps in the system for collecting information about disruptions on the railway network. The conclusion underlined in the paper is the necessity to develop a coherent system for collecting data on disturbances, which will contribute to the development of a model of knowledge management about disruptions and will allow to coordinate the network to increase its reliability.

The research on the multimodal transport development within the cross-border area is a result of identified gaps in the system solutions and cooperation between stakeholders of three countries: Poland, the Czech Republic and Slovakia. Freight transport is an especially complex problem. It is an area that is not comprehensively recognized in the context of cross-border cooperation. The results of the research presented in this paper are the continuation of analyses performed within the scope of the international project framework TRANS TRITIA. At the moment, transport policy assumes the struggle for the utilization of multimodality within freight transport. This is justified by the need to reduce external transport costs. At the same time, this necessitates actions of a technical, organizational, and legislation nature as well as cooperation between stakeholders. The multimodal transport ecosystem is a vision of the transport within cross-border areas that assumes the increase in the flow dynamics within the multimodal transport. The main goal of this paper was the stakeholders’ analysis and identification of their roles in the ecosystem of multimodal freight transport within the Polish–Czech–Slovak cross-border area. The conceptualization of the multimodal freight transport ecosystem was essential to achieving the objective. To achieve the objective, a stakeholder analysis has been performed based on expert research. As a result of the research, organizational projects have been proposed to strengthen the idea of the coevolution of the multimodal transport ecosystem. The key conclusion from the performed research is the declaration that a holistic view of the multimodal transport ecosystem necessitates the appointment of a coordinator who will synchronize knowledge, business, and innovation ecosystems.

Multimodal freight transport in cities is a complex, valid, and vitally important problem. It is more seldom underlined in scientific studies and included in cities’ strategies that devote more attention to passenger transport than freight transport. The increased utilization of multimodal transport matches current transport policy and at the same time, it is one of the most important challenges put before cities striving to achieve sustainable development. In this case, the paper embarks upon the problem of relations between multimodal transport development and the sustainable development of the cities. The objective of the paper is an analysis of the impact of the selected city of the Upper Silesian metropolis on the development of multimodal freight transport and an assessment of the impact of the development of multimodal transport on the sustainable development of the cities of the Upper Silesian metropolis. The authors developed three research questions in order to implement the adopted objective. The process of looking for the answer included four stages. Within the first and second stages, the literature studies and experts’ research allowed for identifying key factors of the multimodal transport development that a city may have an impact on. In the third stage, the research was two-fold and was based on a questionnaire and scenario analysis. Due to the individual character of each of the cities, scenarios were developed for Katowice, being the main economic center of Upper Silesian and Zagłębie Metropolis. As a result of the research, factors have been identified that must be included in a strategy of a city that strives for sustainable development. The last stage of the research focused on the initial concept of the multimodal transport development impact assessment on sustainable development of the cities. Conclusions developed at individual stages allowed for answering the research questions.

As the demand for transport is growing, more and more attention is being paid to its quality aspects. These include, among other things, efficiency, safety, and a continuous effort to reduce external costs. That is why the transport policies of the EU countries and individual regions are increasingly addressing the issue of sustainable transport development. Multimodal transport, which is seen as a key element to effectively counterbalance the dominant role of vehicle transport in the economic progress of the European Community, plays an important role in these programmes. For consistency and continuity of freight flows, cooperation between neighbouring countries and regions is essential. The future of multimodal freight transport within the cross-border area of Poland, Czech Republic and Slovakia is not as evident as the transport policies imply. Therefore, the purpose of the paper is to identify a set of factors determining the development of multimodal transport within the cross-border area of TRITIA (The European Grouping of Territorial Cooperation of the four regional governments of Moravian-Silesian Region (CZ), Opole Voivodeship (PL), Silesian Voivodeship (PL) and Žilina Self-governing Region (SK)) and to develop four scenarios, the execution of which in the 2030 perspective depends on the implementation of cross-border infrastructure and organisational projects and the increasing level of cooperation in the field of multimodal transport. The article contains the methodology for developing scenarios of multimodal freight transport development. The research showed that initiating activities targeted at the development of multimodal transport within the cross-border area requires the involvement of all participants in the process, i.e., all countries (Poland, Czech Republic and Slovakia), along with many different stakeholders. The future development of multimodal transport as provided for in the scenarios is not linearly correlated with the increase in cooperation and the number of implemented infrastructure and organisational projects. It is vital for future research to define the role of stakeholders both in terms of cooperation and collaboration development.

The search for possibilities to increase the efficiency of implementing public services creates prospects for the use of logistics management. However, research on this subject is sporadic. This has been the reason for undertaking research in this area and attempting to develop a concept for the research of logistics management in public networks, which is the purpose of this article. In the course of the analyses, logistics management and public networks were characterised. The focus is on the complexity and problems of public networks, which determine their specificity. Getting to know public networks’ specifics is facilitated by the developed map of relations in public networks and the model of public institution sub-networks. The nature of this article is conceptual and its result is setting the directions and procedure of researching logistics management in public networks.

Distribution enterprises that implement delayed product differentiation establish network relations, invest in flexible resources, accumulate inventory of base products, ensure flexible transport. The aim of this paper is to identify the sensitivity of flexible distribution system with deferred production to the demand fluctuations. The flexibility of distribution system was analyzed in three forms: production infrastructure flexibility, sourcing dedicated resources from a cooperator based on formal relations and sourcing production capacity from the cooperator based on informal cooperation. The research was carried out in the steel products distribution sector. The flagship enterprise of distributions channels were identified, that organize the flows of steel pipes. A flagship enterprise in steel products distribution sector carries out deferred production tasks, selecting machinery flexibility levels and shaping network relations with sub-contractors. Structured interviews were carried out, resources strategies were indicated on the basis of collected primary and secondary data, a reliability indicator was defined and simulation experiments in systems dynamics technique were carried out. The results of the research carried out allowed for the conceptualization of flexible resources strategy of the main link of distribution channels and to direct future research on variables not included in the model, especially disruptions in different models of flexible resources strategy and atmosphere of network cooperation.
