Sustainable transport system refers to desirable combinations of government policies, infrastructure and technologies which minimise environmental impacts and refers to economic and social issues. The aim of this paper was to study the possibilities and challenges for application environmental life cycle assessment (LCA) methods for support sustainable transport. LCA is the most holistic approach of assessing environmental impact and selecting eco-innovation in transport sector. The role of LCA in the development of green transport taking into account challenges related to transport policy, the European Commission's 2050 strategy as well as the circular economy was presented. In European Union countries government actions are aimed at increasing the use of alternative fuels and supporting the development of electromobility. Transport sector needs new and appropriate tools like LCA that will support decision making regarding the development of mobility with alternative and future fuels, technologies and materials etc. in whole vehicle’s life cycle.
Crew scheduling is one of the major phases in crew management in large transportation networks such as railway, bus and airline systems. The scheduling of crews is usually considered as two problems: the crew pairing problem and the crew assignment (rostering) problem. These problems are solved sequentially. In this paper we focus on the crew pairing problem in the railway systems. A pairing is a round trip starting and ending at the home base, which is susceptible to constraints that arise due to laws and regulations. The purpose of the crew pairing problem is to generate a set of pairings with minimal cost, covering all trains (timetabled train service with a unique train number) that the company has to carry out during a predefined time period. In this paper, we present an optimization model for solving train drivers pairing problem arising from a practical application. The model can determine the shortest length of duties (it means sum of durations of all duties). In order to evaluate the results from the developed model, they are compared with the results obtained by the planner. The results show that the proposed model is capable of efficiently generating the optimal work schedules for the train drivers in a reasonable computation time.
The problem of railway transport safety is one of broad issues, and although it concerns only the sphere of railway transport, it is impossible to assign it only to this sphere of economic activity of the state. The security area contains issues in such sciences as law, sociology, psychology, technology or logistics. In general, the concept of security is an interdisciplinary concept. This is particularly evident in the case of rail transport, where many factors determine safety and it is difficult to determine which of these factors plays a dominant role in the assessment of transport safety. Rail transport is directly carried out by railway, cargo or passenger vehicles. The technical condition of these vehicles directly determines the safety of transport, whereas the newly produced vehicle is not automatically received the status of a safe vehicle, i.e. one that can carry out railway transport.
There is, not only in Poland, but in other countries also, the procedure for the railway vehicle to be put into service and the process of implementing this procedure itself is called the homologation of a railway vehicle. This process includes several stages in which research units and state administration units participate. The final result of this process is the issuance by the Office of Rail Transport of a document called the Certificate of admission to traffic. As the actual operational events have shown, despite the fulfillment of procedural conditions, they occur in the further process of operation the railway derailment due to the poor condition of the track infrastructure, which is not fully taken into account in this approval process.
The subject of the article will be the presentation of the homologation process of a rail vehicle with a special discussion of the condition of the track infrastructure and its consideration in this process. An example of a railway event (train derailment) will also be presented, in which the condition of track infrastructure played a significant role.
As a part of the sustainable urban transport policy, the alternative methods of moving towards individual car transport are promoted. Their aim is to reduce the emission of harmful substances and noise, as well as to reduce the phenomenon of congestion. One of the recently promoted methods of movement in the urban areas is the carsharing system. It allows to reduce the number of private cars and creates the possibility of individual movement of people who do not have their own means of transport. The cooperation of private carsharing operators with municipal transport operators allows for the mutual integration of these entities. In order to be able to improve to carsharing system, the activity of using services of carsharing should be examined. It seems to be easy because operators record data on the history of the rentals of vehicles. The paper presents an analysis of car sharing activity on the example of a selected system operating in Poland. The analysis was made on the basis of data from the carsharing system operator, covering a period of three months. The histogram of the total number of reservations and rentals is presented, depending on the factors selected. The analysis allowed to formulate conclusions and recommendations that could improve the effectiveness of functioning of the carsharing system in Poland.
The organization of the order picking process has the greatest impact on the efficiency of the warehouse or distribution center, and thus on the supply chain efficiency. From the moment of accepting the customer's order through its completion to the time of shipment, there are many possibilities of making mistakes and errors both in terms of accuracy and completeness, as well as time-wasting. The paper presents the problem of order-picking in a typical warehouse in which items must be collected manually by the workers available in a given period of time (e.g. working shift). The goal is to develop a plan that minimizes the number of pickers that must be involved in picking orders in a given section of a warehouse and simultaneously optimizes the distance covered by the pickers. Mixed integer programming model for the order-picking and route planning problem is formulated and the heuristic based on genetic algorithm and TSP r-opt technique is proposed to solve it. Proposed genetic algorithm uses a crossover dedicated to the special representation of the solution coding order-picking plan and four different mutations allowing for extensive exploration of solution space resulting in a high quality, reliable order-picking plan. The quality of the proposed solution is evaluated against the data coming from one of the real warehouses.
Since the transport of goods was entrusted to third parties, there was a need to mark the goods. From the initially primitive methods to the present day, where the waybill plays a key role in transport logistics, the ways of freights significance have undergone significant evolution. One of the most important steps was, among others, the standardization of packaging and the appearance of EUR pallets. The introduction of IT tools, globalization of services including not only transport but also packaging management, storage services, redistribution of goods, insurance services and many more, create new development prospects. The logistic tools that are currently applicable to the expanding logistics area and the requirements are becoming insufficient. Thus, the industry is waiting not only for another evolution but more likely for a revolution. The change of the transport logistics model, in particular in the context of returnable packaging, resulted in the emergence of, among others, pallet pools on the market. New models, extended services and innovative economy 4.0 require new technical solutions. One of such solutions may be the introduction of a digital transport pallet. The assumption of this solution is a global exchange of information regarding the packaging along with the content, transport conditions as well as the current geographical position. The article presents problems resulting from marking goods, potential methods of freight monitoring, and proposes a new solution for permanent marking of transport pallets with radio tags. A built-in technology demonstrator was also presented.
According to Schumpeter’s innovation theory of profit, the innovation is placed as a core element of an entrepreneur strategy to reduce costs or rise the demand for products, thus to increase the profit. A lot of industry research results verify that theory positively proving that financing innovations leads to the return of 20%, up to 50% at the case of successfully commercialized solutions, depending on the case and the method of measuring the impact. However, these reasons show not only how important is the issue of innovations in business theory and practice, but also cause some problems referring mainly to the identification, implementation and assessment of innovation outputs. These problems are appropriate for all industries, including logistics, which 10% share in GDP in average makes this area of business activity worthy to research. Up to date the logistics literature deals with the mentioned problems of innovations in analytical and separate way, with little attention to a conceptual approach. For instance, there is still a discussion on what can be named as an innovation in logistics, no systematization works have been done to classify innovations and neither identification nor assessment methodology standards have been created and then applied in logistics practice.
Based on the above reasons, the purpose of this article is to formulate a contingency approach as the author proposition to deal with one of the above mentioned problems, namely identification of innovations for logistics. Thus the thesis of this article states that the contingency approach is the right method to identify logistics innovations.
Due to the nature of contingency approach, the main method to perform the mentioned purpose of this article is a literature review, an analysis of the actual propositions, and creation of conception of the contingency approach for identification logistics innovations. It is supported by modelling method at the form of block scheme of this approach. The proposed thesis is verified according to the confirmation method, by the course of logical reasoning at the form of reduction, induction, and deduction to positively justify the formulated conception.
The obtained results of the research process are included at two meritorious chapters of the article. At the first one, actual ideas, conceptions and approaches are analyzed. Based on the findings the contingency approach is conceptualized and suggested as the most appropriate attitude to identify logistics innovations at the next chapter. These two chapters are supported by discussion and conclusions, where limitations of the contingency approach are presented.

The factors including distortions in the correct implementation of supply chains include technical and non-technical factors. For non-technical factors we may recognise: incorrect assessment of strategic options, external attestation, legal regulations, functioning of the natural environment or socio-cultural factors, such as the loss of social responsibility by events triggered by domestic and international media It is a significant problem due to political changes in Central Europe since 2015 which have had a huge impact on societies. The consequences of well-planned manipulation is its influence on business relations between participants of supply chain. The aim of the article is to analyse and evaluate the relationship between media coverage and the resilience of global supply chains. The basis for the assessment was qualitative research carried out on a representative sample of Poles in the years 2015 - 2018 (98 interviews) and quantitative analysis of words on social media (facebook, twitter). The collected data pertained to more than 3 million tweets and 2000 entries on Facebook. The authors also monitored Polish print media, both local and nationwide, including 430 titles in total. In addition, the statements of politicians recognized as social significant, which were conveyed to the public by the media, were analysed. To analyse the source of risk, the “What If” method was applied.
Sustainability plays crucial role in today’s competitive environment. Having CSR strategy implemented in the area of production seems to be not enough. Currently companies realized that they could also be competitive by improving their logistics processes i.e. in terms of implementing more eco-friendly transport management. Sustainability in the area of transport activities can occur as replacing road to multimodal modes. However the multimodal transport is still recognized as complex and problematic solution for many logistics managers. Thus it is rarely chosen by the companies. These challenges can be met through using technology tools for transport planning and management. One of the available solution is a part of ChemMultimodal project toolbox - Intermodal Links platform. On such a digital platform companies can easily plan different scenarios for multimodal transport routes within Europe. It could also further serve i.e. for synchromodality as a new competitive solution on logistics services market. The goal of the article is to present Intermodal Links solution as an example of the tool supporting strategic decisions for increasing sustainable transport solutions. Presented results are based on ChemMultimodal Project implementation. The Project is carried out under Interreg Central Europe Programme between 2016 and 2019.
Supplying troops with foodstuffs is one of the basic factors determining success in armed operations and is part of the professional activity of commanders at all levels of the military logistic structures. At the same time, the European Union's soldiers and citizens are protected consumers and potential victims in the event of targeted food modification. The consumer is aware and knowledgeable about the relationship that exists between the quality of food and its health, including the safety of the products consumed. In the era of limited trust in food products offered and supplied to consumers, producers as well as suppliers must prove, among other things, by having the required certificates, that they are able to manage food safety on an ongoing basis. In addition to the dangers related to non-compliance with the HACCP principles and good hygiene and production practices, targeted activities take on special importance. The literature on the subject has the function of deliberate contamination or food poisoning. The article thoroughly queries Polish literature sources as well as foreign sources, due to the fact that native literature on food defense in the field of management science and commodity science is very poor. The author indicates the possibilities of integration of the proposed system of food defense management with the applicable procedures in the Food Service of the Armed Forces of Poland. This article is based on the analysis of scientific publications and is the effect of observing phenomena occurring mainly in the area of HACCP and the military environment.
Among all operational fluids, the most important is attributed to the appropriate quality of liquid fuels. This is due to the fact that fuels constitute the largest group of operating fluids introduced to trade and the fact that their inadequate quality parameters cause many adverse effects, including min. deterioration of the functional characteristics of the engine, increase in the costs of vehicle operation, deterioration of reliability and durability of the machine or emission of harmful components of the exhaust gases emitted to the environment. Therefore, many different technical, organizational and legal projects are planned so that the quality of fuels in the supply chain will not deteriorate. One of such undertakings is a properly designed system for maintaining the quality of liquid fuels in the supply chain: from the source of supply to the end user. Systems operating in relation to liquid fuels are not perfect and have some functional and organizational defects. Therefore, it seems advisable to carry out a thorough identification of existing solutions and to identify the possibility of their improvement. The article presents the results of research on the fuel quality monitoring and control system in Poland carried out by the author in 2009-2018.
Our contribution is focused on the problem of the use of electric vehicles in freight transport. The area of potential use of electric cars is affected by a high level of uncertainty in terms of efficiency and operating costs. The analyzed problems are related to the limited charging station infrastructure and the planning of driving performance with respect to the capacity of the batteries and the total time spent on the route. Current charging stations for passenger cars cannot be used in case of freight transport, so there is a need to create an overall infrastructure for such type of electric vehicles. Our paper presents some optimization mathematical methods in connection with the application for the purpose of charging station definition, charging station location, etc. Main effect of the application of mathematical models is the efficient use of resources and the mitigation of environmental impacts in the field of construction of new charging stations and their location within existing logistic and production parks.
Logistics management has become more and more of the forefront of management interest in industrial companies, which are aware of its key importance, especially in conditions of dynamic environment and rapid growth, which in addition to opportunities and growth of sales also brings risks and new problems. The aim of this article is to identify and introduce barriers to logistics management of a fast growing enterprise based on the framework of logistics maturity models and case study from the automotive industry company and to design a system of prioritization for removing identified barriers. The outputs of this study will help management of fast growing businesses recognize or anticipate barriers in improvement of logistics processes and provide support for effective decision-making to overcome these barriers during the dynamic growth of the business.
Security challenges of a contemporaty world require new NATO strategy especially in the area of long range deployment. Fast movement of troops and equipment within Eastern Europe during peacetime, crisis or state of war depends on many factors. Effective transport infrastructure belongs to the one of the most important elements. Rising number of NATO trainings and exercises like Dragoon Ride, Sabre Strike or Atlantic Resolve in countries such as Poland, Romania, Bulgaria, Latvia and Estonia shows the real level of capabilities in such particular areas like military mobility and logistics. Based on the official reports and data collected there is a visible difference between the rail, road, sea and air infrastructure standards and condition in the western and eastern part of Europe. What is more, units coming from U.S. or Canada are not familiar with transport standards and procedures in Eastern Flank countries. Identification of all exsisting barriers to deployment of troops and heavy equipment require better cooperation between military and civilian agencies. Expiriences of Polish Armed Forces collected, shows many disadvantages of existing transportation system - especially in the area of road and rail transport. The main purpose of this paper is to analyze and evaluate possibility of Poland as a Host Nation Country (HNS) in the area of military transport with some recommendations.

The article ends with description of the possibilities of further implementation and development of the technology under study.
Dynamic economic and technological development puts more and more demands on every branch, including road transport. Maintaining a significant position on the market is possible due to the applications of solutions supporting the efficiency and quality of transport, including through telematic solutions.This is particularly important in the case of transport of food (especially fresh products), which are much more sensitive to transport conditions. Under the influence of inadequate temperature, air humidity loses its quality, fades, withers or rot and is unfit for consumption. Therefore, it is very important to maintain proper conditions of transport and to make people responsible for the transport chain of these articles aware of the responsibility for decisions and possible preventive solutions.The aim of the article is to analyze selected environmental parameters inside the refrigerated semitrailer in relation to the quality of the transported goods. The scope of work included the analysis of 4 parameters: temperature, humidity, pressure and light. The analysis was carried out using specialized sensors recording inside the means of transport.Three refrigerated trailers were accepted for analysis. The acquired data support management processes and contribute to increasing the level of customer satisfaction.
As a result of the analyzes carried out at work, it was found that the use of measurement sensors and dedicated solutions has a positive impact on the quality of the transported product and the efficiency of delivery, and thus increased customer satisfaction.
