    Opis:
    The considerations included in the paper apply to the problem of the multi-criteria evaluation of transportation systems with constraints on delivery times in supply chains. For this reason, the identification of the transport network model and the nature of the configuration of the supply chain itself was carried out. In addition, a review of issues of the multi-criteria evaluation were done with respect to transportation systems. Later, the problem of the transport service of a distribution system were formulated and then, the results were analysed using the multi-criteria method. Finally, the paper examines the impact of the threshold of compliance and the threshold of non-compliance on of the final outcome of the solution.
    Rozważania zamieszczone w artykule dotyczą problematyki wielokryterialnej oceny systemów przewozowych przy ograniczeniach na czas dostawy w łańcuchach dostaw. W tym celu dokonano identyfikacji modelu sieci transportowej oraz istoty konfigurowania samego łańcucha dostaw. Ponadto dokonano przeglądu problematyki oceny wielokryterialnej w aspekcie systemów przewozowych. W dalszej części sformułowano problem obsługi transportowej systemu dystrybucji, a następnie przeanalizowano otrzymane wyniki wykorzystując metodę wielokryterialną. W końcowej części artykułu przeanalizowano wpływ wartości progu zgodności i progu niezgodności na wynik końcowy rozwiązania.

    Opis:
    The degree of emission limitation achieved through improved efficiency of combustion engine vehicles can no longer set off additional emissions caused by increasing traffic activity. As the restriction of greenhouse gas emissions from cars is expected to be particularly difficult, the air pollution and excessive dependence of road transportation on oil cannot be improved without the implementation of new mobility concepts (biofuels, hybrid drives, electric vehicles). The lack of these concepts, as emphasized in the White Paper, will preserve transportation dependence on crude oil so deeply that only 10% of energy will be derived from renewable sources. According to this scenario, until 2050 the CO2 emissions in the transportation sector will increase by one-third compared to 1990. Moreover, there will be an increase in the costs of traffic congestion until 2050 by ca. 50%. The difference in the availability between central and peripheral areas and social costs of accidents and noise pollution will increase as well (EC, 2011). The goal of the paper is to determine whether the implementation of a new solution would actually improve the situation of air pollution, traffic noise, etc. To this end, the paper proposes a comparative analysis of cars with various sources of energy using a multi-criteria scoring method. Notably, this method has never been used in such a confrontation before. Until now, the multi-criteria assessment methods have been used i.a. to evaluate implementation variants for infrastructural investment projects in rail transport (Jacyna and Wasiak, 2007), traffic flow distribution (Jacyna and Merkisz, 2014; Wasiak et al., 2017), supply chain efficiency (Jacyna-Gołda et al., 2018), effectiveness of vehicle allocation for tasks in supply chains (Jacyna-Gołda et al., 2017), etc.

    Opis:
    Transport is a sector that is said to be negatively affecting the environment. The continuous development of transport increases the negative impact on the environment and civilization. In the article authors present the parameters that were used to describe the size of harmful transport exhaust emissions, in particular by means of road transport and the factors affecting their size. The areas where the level of concentrations of air pollutants are exceeded in Poland were characterized and analysed. Also examples of the stream traffic distribution in the selected area of the transport network were presented.

    Opis:
    The basis of each IT system is data exchange both between individual modules of program and between program and user. The number of exchanged data and the number of operations on the data, which should be performed, require application of professional tools allowing for collecting and performing operations on multiple types of data. One of these tools are databases, which are an essential part of any IT system. With database designing are connected many decision problems which can occur both during the construction of database management system and at the stage of integration of entire user application with developed database. The article presents typical decision problems connected with designing of databases. These problems mainly concern sphere of information technology (including the programming language or recovery mechanism of database after the failure). Database architecture for typical IT system from the point of view possible paths for users were discussed, and role of catalogues played in development of database were presented. In addition, modular structure of the database, which was developed for the system SIMMAG3D for modelling and visualization of warehouse facilities in 3D was shown. This system is being developed under a project financed by the National Centre for Research and Development. We discussed in detail one of the essential elements in developed database - catalogues of means of external and internal transport, non-mechanical equipment and accessories which are essential from the point of view of the work load.
