    Opis:
    The article refers to the problem of assigning the aircrafts to stops points on the apron. The aim of this paper is to develop the algorithm, which will be used to this assignment. The assignment problem of aircrafts to stops points is the complex decision problems, which refer to the problems of designating the minimal path in the graph. The assignment model was described, i.e. decision variables, constraints and the criterion function. Decision variables take the binary form and determine the connections between the elements of infrastructure of the apron, i.e. touchdown points, intermediate points and stop points. Constraints take into account the number of aircrafts in the given period, the number of unoccupied stop points. The criterion function determines the minimum driving time of the aircraft on the apron. In order to designate the routes in international transport the heuristic algorithm, i.e. ant algorithm was developed. The steps of building this algorithm were presented. This algorithm was verified in the C# programming language. The results generating by the presented algorithm were compared with the results generating by the random algorithm.

    Opis:
    The development of railway transport in the current times is very noticeable, it is connected with the growing needs of movement as well as the development of information engineering. The increase in the demand for transport requires the implementation of solutions that increase the efficiency of the transport system. Both long-distance, agglomeration and metro railways can use different systems due to their specificity. Nevertheless, there is a noticeable trend in the development of systems supporting or even replacing the driver by the automation of selected activities. Such systems allow to reduce trains headway and thus increase the capacity of the line. CBTC class systems (Communications-based train control) belong to automatic train systems and are based on wireless transmission. The main purpose of using such systems is to increase the frequency of running trains while maintaining the level of safety. Computers that are on the system equipment record, process and analyse very large amounts of data. An essential element of such systems are recording units. The parameter recorders can be divided into technical and legal ones. However, for CBTC class systems, there is no obligation or requirement to use legal recorders as it is in the case of ETCS. However, it is necessary to use event recorders, and these are subject to the requirements set out in the PN-EN 62625-1: 2014 standard. The recorders are a very important component of safety systems, which is why they were analysed in this article. Both the driver, the vehicle and the infrastructure should be subject of continuous monitoring. The occurrence of an adverse event (not necessarily leading to an incident or accident) should be analysed and used to improve safety procedures. Currently, automatic systems are still developing and we are not able to accurately assess what the causes and effects of certain events may be, which is why data collection and analysis is particularly important. The article presents the general specification of the CBTC system. The parameters and properties of driving recorders should be presented.

    Opis:
    The paper presents the issue of container handling processes at a railroad intermodal terminal. The main purpose of this paper is the assessment of the handling equipment utilization and the associated energy consumption. The authors analyze how the road vehicle availability at the moment specified in the containers loading schedule influences the total handling equipment operation time as well as the necessary number of handling equipment. It is assumed that vehicles planned for loading of import containers may be late for loading, which causes some interruptions in the loading schedule. Such interruptions are identified with the necessity to handle the next container for which the road vehicle is already waiting, which influences the handling equipment utilization and, finally, energy consumption. The general mathematical model of the problem developed in the FlexSim simulation software was presented. Based on the simulation research, it pointed out that proper road vehicles loading sequencing can significantly reduce handling equipment operation time, and thus energy consumption, costs, and CO2 emissions. The literature analysis presented in the paper indicates that most of the research in the field of intermodal transport is focused on operations optimization in container ports. There are differences between two types of intermodal terminals in operation procedures and rules. That is why the authors decided to undertake the problem of road vehicle sequencing including their random availability and its influence on handling device operation time, which has not been considered in the literature so far.

    The paper presents a certain approach to fleet management in the company, taking into account the mobility of employees and the selection of vehicles for tasks. The main objective is to indicate the factors that significantly affect the proper selection of vehicles for the task, as well as concurrently meeting recipients' needs. The general model for fleet management was presented, taking into account not only the mobility of employees but also the method of obtaining funds for the replacement of greener cars. The current approach is based on the car purchase model in the form of credit, low-purchase leasing, and supervision over the use process and operating costs by the company's internal resources. The problem solved in the article concerns the analysis of entrusting fleet management to specialized Car Fleet Management (CFM) companies. It was pointed out that in this calculation model, CFM companies have to take into account many variables related to vehicle selection and mobility of employees in order to perform tasks. In this article, particular attention has been paid to the areas that CFM analyses when choosing a vehicle for a given company.

    Opis:
    Modelling of transport systems is a complex issue requiring taking into account many factors that allow for the mapping of the real system and thus allowing decision support. In the era of increasingly higher requirements for services, transport also faces the challenges of sustainable development. Therefore, it is necessary to conduct research both in the sphere of technical and organizational solutions aimed at limiting pollutant emissions. Mapping in the model the negative impact of transport on the environment allows for planning the implementation of the transport service taking into account the pro-ecological criterion. This is particularly important in urban areas where traffic and especially heavy goods vehicles are particularly onerous for inhabitants and require limiting transport work in the city area and the use of environmentally friendly rolling stock. The aim of the article is to present the considerations regarding the modelling of transport systems including pollutant emissions. The article introduces the problem of cargo distribution and a review of the models of estimation of pollution emission in the micro and macro scale was carried out. Next, a mathematical model was proposed which is a variant of the Vehicle Routing Problem of the so-called Green VRP. In the distribution model was used COPERT methodology for estimation of harmful substance emission. In article examples of calculations carried out on the example of the city of Warsaw for the organization of cargo distribution due to the CO emission criterion was presented. The article ended with a short synthesis of the work carried out.

    Opis:
    This paper presents the problem of the assessment of the supply chains in the context of their effectiveness. In this paper the concepts of a supply chain and effectiveness were characterized. The supply chain is a structure of entities which are connected with each other by the use of material and financial flows and functional, structural, technological, economic and information dependencies. Entities such as: suppliers, final recipients, entrepreneurs, warehouse facilities, supply centers, logistics operators, carriers, etc. perform material flows from suppliers to recipients. The concept of efficiency, in general terms, refers to economic rationality and means the relationship between the achieved or expected effects and the expenditures incurred. Additionally, indicators of measuring the effectiveness of the supply chain were described. In order to assess the effectiveness of the supply chain the decision model was developed. Optimization is crucial in decision support systems. The development of an appropriate model for mapping the behavior of a real object or system and formulating an optimization task is a necessary activity in effective management. This is even more important if we want to be competitive. Along with the development of decision support systems, as well as the development of systems for data acquisition on the system functioning, which feed optimization models in ever more detailed form, complex decision models are created that take into account many optimization criteria and require a large amount of data. It allows, however, to ensure the sustainable development of the system and simultaneous implementation of its basic tasks. The main aim of this paper is to present the stages and assumptions of the model for assessing the effectiveness of the supply chain. The main data input, constraints of the model, the criteria functions were determined.

    Opis:
    The article presents the problem of containers storage on a storage yard in an rail-road intermodal land and the emission of harmful exhaust gases into the atmosphere. This issue was considered from the point of view of the distance traveled by transshipment devices, the duration of loading work and the resulting energy expenditure and CO2 emissions. The research was dictated by the current limited number of publications in the area of the distribution of containers on storage yards in rail-road intermodal terminals. The vast majority of the literature is devoted in this field to marine intermodal terminals, which operating characteristics are different from inland terminals. The importance of this problem resulting from the growing turnover of containers transported by rail transport was also pointed out. The systematic increase of this type of transport and the depletion of the intermodal services' operating capability makes it necessary to improve the processes taking place in the storage area. The possibility of improving these processes in addition to the use of computer tools is also realized through the use of modern transshipment devices. Depending on the area of their operation and the scope of their application, these devices use various types of power supply, which affect environmental pollution. In the case of gantry cranes considered in this article, their power supply may come from both combustion engines, hybrids and electric engines. Therefore, from the point of view of minimization of harmful exhaust gases emissions into the atmosphere, in the article, the problem of choosing the device for carrying out transshipment tasks was also taken up. For the purposes of the research, the processes of container handling in the rail-road intermodal terminal have been presented in detail. A review of literature in the field of container storage methods and strategies was carried out. The considered container reloading processes in the wagon-yard relation were modeled in the FlexSim simulation environment. The constructed simulation model was used to develop 5 variants of the distribution of containers on the storage yard as a function of their location on the train. Container deployments on the storage yard were carried out for both random and fixed distribution of containers on the train. In the case of a random arrangement of containers on the train, the tests were carried out for 100 replications. On the basis of simulation tests, the distance covered by the transshipment device (RTG crane) and the time of carrying out the loading tasks in particular variants were determined. Using the crane data provided by the crane manufacturer, the energy expenditure was calculated in individual variants for different power supply methods (combustion engine, hybrid, electric engine). The obtained results allowed the selection of the best strategy for containers storage, taking into account the amount of CO2 emitted to the atmosphere by transshipment devices.
    W artykule przedstawiono problematykę składowania kontenerów na placu składowym w lądowym terminalu intermodalnym i związaną z tym emisją szkodliwych związków spalin do atmosfery. Zagadnienie to rozważano z punktu widzenia dystansu pokonywanego przez urządzenia ładunkowe, czasu trwania prac ładunkowych oraz wynikającego z tego wydatku energetycznego i emisją CO2. Przeprowadzone badania podyktowane były dotychczasową niewielką liczbą publikacji na temat badania rozmieszczenia kontenerów na placach składowych w lądowych, kolejowo-drogowych terminala intermodalnych. Zdecydowana większość literatury poświęcona jest w tym zakresie morskim terminalom intermodalnym, których charakterystyka pracy różni się od tej w terminalach lądowych. Wskazano także na istotność tego problemu wynikającą z rosnących obrotów kontenerów przewożonych transportem kolejowym. Systematyczny wzrost tych przewozów i wyczerpywanie się zdolności obsługowych terminali intermodalnych powoduje konieczność usprawniania zachodzących tam procesów. Możliwość usprawniania tych procesów oprócz zastosowania narzędzi komputerowych realizowana jest także dzięki wykorzystaniu nowoczesnych urządzeń przeładunkowych. Urządzenia te w zależności od obszaru ich działania i zakresu ich zastosowania wykorzystują różne rodzaje zasilania, które w większym, bądź mniejszym stopniu wpływają na zanieczyszczenia środowiska. W przypadku rozważanych w niniejszym artykule suwnic jezdniowych, zasilanie to pochodzić może zarówno z silników spalinowych, hybrydowych jak i silników elektrycznych. Stąd też z punktu widzenia minimalizacji wielkości emisji szkodliwych związków spalin do atmosfery w artykule podjęto także problematykę wyboru urządzenia do realizacji zadań przeładunkowych. Na potrzeby badań szczegółowo przedstawiono procesy obsługi kontenera w lądowym terminalu intermodalnym. Dokonano przeglądu literatury w zakresie metod i strategii składowania kontenerów. Rozważane procesy przeładunku kontenerów w relacji wagon-plac składowy zamodelowano w środowisku symulacyjnym FlexSim. Zbudowany model symulacyjny posłużył do opracowania 5 wariantów rozmieszczenia kontenerów na placu w funkcji ich rozmieszczenia na pociągu. Badania rozmieszczenia kontenerów na placu składowym wykonywano zarówno dla losowego jak i ustalonego rozmieszczenie kontenerów na pociągu. W przypadku losowego rozmieszczenia kontenerów na pociągu próby wykonywano dla 100 powtórzeń. Na podstawie badań symulacyjnych określono dystans pokonywany przez urządzenie przeładunkowe (suwnicę RTG) oraz czas realizacji prac ładunkowych w poszczególnych wariantach. Wykorzystując podawane przez producenta suwnic dane o wielkości zużywanej przez suwnicę energii obliczono jej wydatek energetyczny w poszczególnych wariantach dla różnych sposobów zasilania (silnik spalinowy, hybrydowy, elektryczny). Uzyskane wyniki pozwoliły na wybór najlepszej spośród rozważanych, strategii składowania kontenerów na placu przy uwzględnieniu wielkości emitowanego przez urządzenia przeładunkowe CO2 do atmosfery.

    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.

    Opis:
    The article presents selected aspects of shaping pro ecological transport system. Correct, socially responsible, economically reasonable and far-sighted allocation of resources is one of the basic tools of sustainable development shaping. In the case when this concept in a narrower sense refers to shaping the national transport system one can distinguish the general problem: how to invest financial resources in the development of the transport system and how to manage this system in order to one can say about it as "sustainable". The article presents the principles of creating scenario analyses, discusses the procedure and elements of an algorithm for the development of scenarios of the sustainable transport system. The procedure for conducting scenario consists of three stages of research. The analyses were conducted by the use of EMITRANSYS model. The EMITRANSYS model was developed in Visum. Its main elements are the network model, demand model, integrated database and a set of scenarios of an analysis of transport system development. The simulation model EMITRANSYS was developed under the PBS1 project "Shaping of the pro ecological transport system” financed by the National Centre of Science and Development. The project was realized within the consortium consisting of the Faculty of Transport of The Warsaw University of Technology and the Faculty of Machines and Transport of The Poznan University of Technology in the years 2012-2014.

    Opis:
    The paper is a result of research work carried out under the project EMITRANSYS for shaping ecological transport system. The paper presents selected aspects of emission and concentration of harmful compounds of exhaust gases generated by road transport. It also presents the share of harmful compounds emitted by road transport in comparison with the emission from other sectors of economy. Transport policy should encourage the usage of energyefficient and less environmentally damaging modes of transport and their efficient use. The paper analyses the emissions of selected pollutants and their estimated contribution to the total emissions of road transport. It also presents selected aspects of the identification of areas with the highest emissions of harmful compounds in Poland against the European Union. This analysis provides a basis to identify the instruments to prevent and reduce pollution arising from transport activities. In particular, variable emission of selected components of fumes according to the velocity of passenger vehicle. the measured values for NO2 concentration in the UE countries in 2011, the measured values for CO concentration in UE countries in 2011, the measured values for PM10 concentration in UE countries in 2011, the measured values for PM2.5 concentration in UE countries in 2011 are presented in the paper.

    Opis:
    The article is a result of research work carried out under the project EMITRANSYS for shaping ecological transport system. The paper presents selected aspects of multi-variant distribution of traffic into transport network for defined scenarios of transport system development. Distribution of traffic on the network is made due to the global criterion function. Partial criteria for distribution of traffic are: external costs, marginal costs and average costs of the transport services expressed in monetary units and in emission units. An important aspect of the development of transport network is to include the external costs of transport activity to economical counting. The harmful components of exhaust gases, external costs for each mode of transport, list of selected external costs for each mode of transport [eurocents/vehicle-km], structure of communication between Warsaw - Gdansk, characteristics of connections in the communication network between Warsaw and Gdansk, distribution of passengers stream in relation Warsaw – Gdansk, the distribution of the passengers stream in relation Warsaw – Gdansk for the second scenario according to criterion of average and marginal costs are presented in the paper.
