The growth of technology and the increasing competitiveness and opportunity of digital services have meant that the traditional logistic sector has changed dramatically. New technology and globalization affect the need to use solutions known to the IT industry. In recent years, we have seen significant technological growth, from smart devices communicating with each other via the IoT (Internet of Things) to artificial intelligence, and the changes it brings in the future. However, the role of user interface design in enhancing the user experience of mobile applications, such as journey planners, has been overlooked. Given the knowledge of the environmental impact of transport systems, it is important to convince users to use more sustainable modes of transport. Transport systems account for 20% to 25% of global energy consumption and carbon emissions. The aim of the article is to explain the process of creating a user interface for a public transport journey planner application that serves as a personal travel assistant. In addition, a competitive audit and research on a small group of users was also carried out. The conducted research and the audit of the competition were crucial in the ideation process, which became the basis for the first wireframes of the application. This was made possible by using the powerful Figma tool, which allowed for a more detailed design of the application’s appearance and functions. The resulting design of the application interface is a proposed solution to some of the user problems detected during the study. The final prototype needs to be turned into a real product to serve users. For this purpose, a developer must be provided with the prototype, who will bring the application to life using programming tools.

Alternative fuels (refuse-derived fuels—RDF) have been a substitute for fossil fuels in cement production for many years. RDF are produced from various materials characterized by high calorific value. Due to the possibility of self-ignition in the pile of stored alternative fuel, treatments are carried out to help protect entrepreneurs against material losses and employees against loss of health or life. The objective of the research was to assess the impact of alternative fuel biodrying on the ability to self-heat this material. Three variants of materials (alternative fuel produced on the basis of mixed municipal solid waste (MSW) and on the basis of bulky waste (mainly varnished wood and textiles) and residues from selective collection waste (mainly plastics and tires) were adopted for the analysis. The novelty of the proposed solution consists in processing the analyzed materials inside the innovative ecological waste apparatus bioreactor (EWA), which results in increased process efficiency and shortening its duration. The passive thermography technique was used to assess the impact of alternative fuel biodrying on the decrease in the self-heating ability of RDF. As a result of the conducted analyses, it was clear that the biodrying process inhibited the self-heating of alternative fuel. The temperature of the stored fuel reached over 60 °C before the biodrying process. However, after the biodrying process, the maximum temperatures in each of the variants were about 30 °C, which indicates a decrease in the activity of microorganisms and the lack of self-ignition risk. The maximum temperatures obtained (>71 °C), the time to reach them (≈4 h), and the duration of the thermophilic phase (≈65 h) are much shorter than in the studies of other authors, where the duration of the thermophilic phase was over 80 h.

The principal objective of the research was to determine the influence exerted by the implementation of standard quality management systems on the improvement of selected logistics processes in small and medium-sized enterprises, which operate in the textile industry. Empirical research was carried out by the authors in the year 2017 on a group of small and medium-sized enterprises that operate in the textile industry in Poland and Slovakia. The research involved 33 organizations (20 Polish, and 13 Slovak ones). The research process and the analysis of the acquired results made it possible to address the research questions posed and to state, among others, that standardized quality management systems exert a relatively large influence on perfecting selected subsystems and logistic processes in the researched organizations.

The article analyzes the issues concerning customer satisfaction survey with the complexity of handling refrigerated containers at the seaports' container terminals. It aims to determine the criteria to evaluate the port comprehensive service and to examine the opinion of chosen seaports terminals on customer satisfaction with the complexity of handling refrigerated containers. Evaluation criteria of comprehensive service of refrigerated containers in seaports were identified and examined. The analysis of ports opinions on customer satisfaction with the service of refrigerated containers was based on surveys, which covered 5 container terminals located in the Polish cities of Gdansk, Gdynia and Szczecin. The research revealed that according to the ports, complex service primarily affects the high-level customer satisfaction and shorter service time, while implementation of this service regards a good level of customer service and price.

Recent years have seen a dynamic growth of ecommerce. This links to technological developments, an increase in the number of people who have access to and actively use the Internet, and the use of mobile devices. The aim of the paper is to present the results of a questionnaire survey of the factors behind the development of e-commerce services. Besides, the paper defines the interdependence between the frequency of internet shopping and the logistic aspects of e-commerce. A hierarchy is also established of the degree of satisfaction as regards the quality criteria of e-commerce services. The analysis covers data from a questionnaire survey of 100 customers using ecommerce in Poland. The respondents were customers using e-commerce services aged between 20 and 24. The questionnaire was based on a five-point Likert-type scale of between 1 and 5. The survey was qualitative and nationwide. The analysis was done using the Statistica 10 software. The Pearson correlation was chosen from amongst the methods available to determine the impact between the surveyed variables. Firms that provide e-commerce services aim to fulfil the ever increasing needs and expectations of their customers. They attach a lot of importance to the quality of customer service which is demonstrated by the high scores awarded by the respondents.

The reliability of supply of the logistics systems is the one of the most important factors determining the competitiveness of businesses. The main purpose of this paper is to assess the reliability of supply of a given system with the use of warranty analysis, based on the Nevada chart. The reliability analysis performed is done in the following way: shipping and warranty return data of a given supply system are converted into a classic data form. Then, the life data analysis is performed, which allows to obtain the given reliability indicators and predict the future returns of the products and services. The paper consists of some useful reliability measures, that may be used in the assessment of reliability for the supply system. Used reliability indicators may be the basis for the development of the preventive tasks to reduce the future returns. The presented approach for reliability assessment of supply system discloses its applicability. Forecasting the future returns and determining the selected reliability measures may be applied in any supply system. It is valuable for the identification of the weakest product or service and it is necessary for developing further preventive activities.
