Opis:
The aim of this research is to propose particular measures aimed at streamlining costs in terms of operations in a selected company. A specific proposal is based on the concept related to using services of the transport databank. As at least two out of five major carriers of the investigated company resell shipments to other carriers on such portals, the company could reduce the transport costs by entering shipments into the transport databank on its own. One out of three selected providers will be chosen using multi-criteria evaluation methods, specifically, the Analytic Hierarchy Process (hereinafter referred to as AHP) and the Base-criterion method. Determination of the weights of criteria will be carried out using the Saaty method of quantitative pair wise comparison and the Fuller pair wise comparison method. In this paper, the presented methods are applied for the example of a specific company specialized in the manufacture of metal storage racks and steel structures. In the Czech Republic, the company employs 65 employees in production, storage and administration. Based on the analytical evaluation of the current situation of the company, relevant measures will be proposed with a required effect on the effectiveness of such an enterprise.

Opis:
This article is aimed at the engineering design of a manipulator, which is pneumatically controlled. It will serve for mounting the compressor of an air suspension system to the chassis of a sport utility vehicle (SUV) produced in the Slovak Republic. The manipulator will be used on an assembly line, on which SUVs are assembled. The designed device belongs to a group of dedicated devices, which are not produced within a serial production, however, it is the only functional prototype. Together with the manipulator structure, a pneumatic part of the assembly line including individual components, schemes and the pneumatic system will be proposed. Within the project process, all necessary customer demands, technical and safety standards have to be met. Moreover, ergonomic requirements for handling the device and other acts on the workplace have to be considered.

Opis:
In 2018, there was an empirical research conducted in passengers' interest in innovative methods of passenger handling within passenger transport in the Slovak Republic. The research determined the knowledge of passengers regarding new methods, namely, NFC technologies, EMV technologies and ABT technologies. The article defines the methodology of choosing an electronic payment system within public transport, followed by partial results of research multicriteria evaluation of alternatives electronic payment system in public transport. For evaluation of variants, an electronic payment system within public transport was the selected method of a total utility.

Opis:
While choosing an electronic payment system intended for an immediate communication of a user (passenger) with an electronic terminal of a service provider (carrier), it is necessary to respect system parameters of presented technologies (NFC, EMV, and ABT). The methodology of choosing an electronic payment system within public transport may be divided into three steps as follows: • outlining criteria for variants evaluation, • multi-criterial evaluation of variants, and • evaluation of empirical research results. The presented article introduces more results of the research within VEGA project solving. Specifically, the article presents results of the multi-criterial expert decisionmaking problem using the WSA (Weighted Sum Approach) method and the TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) method. At the end of the article, there are presented results of empirical research studies focused on an electronic payment system used in public passenger transport. The empirical research studies were realized in the Slovak Republic in 2014, 2016, and 2018.

Opis:
This paper offers a comparison of selected European countries´ approaches to the civil and commercial use of Unmanned Aerial Vehicles (UAV) with the approach and rules set by the Civil Aviation Authority (CAA) in the Czech Republic. The authors specially focused on the differences in the approaches of individual authorities, which regulate the use of unmanned vehicles in the countries concerned in order to emphasise the inconsistency of rules within the European Economic Area. In the other part of the paper, the authors outline the possibilities of using unmanned aerial vehicles (drones), particularly dealing with increasing safety in air transport as a complement to biological protection of airports, and propose their original idea of the system.

Opis:
This article presents the results of an extensive questionnaire survey focused on changes in the transport behaviour of the population of the Czech Republic immediately after the government’s announcement about the measures implemented to prevent the spread of COVID-19. The questionnaire aimed to determine the changes in the use of the mode of transport for regular travel to work, school, or for shopping, as well as to determine the changes in the frequency of these travels according to monitored socio-demographic groups of inhabitants and specified size groups of settlements. This article contains a statistical evaluation of these changes in the transport behaviour of the population using sophisticated statistical tools. A method is proposed for estimating the number of passengers in public transport using a linear regression model based on the data from conducted transport behaviour survey. In this paper, the Data envelopment analysis (hereinafter referred to as DEA method) within the case study in the South Bohemian Region is also used to determine whether the COVID-19 measures have reduced the efficiency of public transport.

Opis:
This research outlines a research study wherein an implementation of the activity-based costing (ABC) approach for cost management in a railway transport enterprise is addressed. ABC is an efficient technique for enhancing the quality of provided services and process complexity of certain railway companies, executing its activities at a regional or international scale. It is one of the new costing approaches that eliminate the inaccuracies and deficiencies of the traditional costing system. Compared to other costing techniques, considerable change lies especially in the way of assigning indirect cost units to activities based on actual causations, and subsequently, assigning activities to the very cost items by the intensity of their consumption. Furthermore, this approach allows decision-makers to identify specific cost item in terms of determining ways of how they can be managed. The main objective of this work is to elaborate a particular study with a draft application of the ABC method encompassing a description of procedure steps, along with relevant quantifications, as well as summarising the results obtained.

Opis:
The prospective of the application of new materials on a polymer base is shown in this work. Given that developed composites can be efficiently used for protection of equipment that is operated at elevated temperatures, the impact of the nature and content of powder mixture, synthesised by high voltage electric discharge, on the thermophysical properties of epoxy composites were studied. Epoxy diane oligomer was chosen as the main component of the binder during the formation of the composites. Polyethylene polyamine hardener was used for cross-linking of epoxy composites, which allows hardening of materials at room temperatures. The selection of powder mixture, synthesised by high voltage electric discharge, for increase of thermophysical properties of developed materials was justified. More so, thermal stability and activation energy of epoxy composites were studied. Permissible limits of the temperature, at which developed materials can be used, were established based on the conducted tests of thermophysical properties of materials, filled by powder mixture, synthesised by high voltage electric discharge.
