Opis:
The article is a review of the transport problems that appear in a marine intermodal terminal. The importance of intermodal terminals has been increasing since the 1980s as a result of the development of containerized international trade. This increase in the handling of containers cause problems connected with securing adequate space for container storage or efficient usage of available terminal loading equipment such as cranes, AGVs, straddle carriers or terminal tractors with trailers. The equipment of a terminal depends mainly on the size of containers flow. The use of this equipment determine the terminal technology and work organization. That is why the classification of intermodal container terminals is presented in chapter 2. This classification was made according to different criteria. To understand transport problems, the identification of processes performed in the marine intermodal terminal is presented in chapter 3. For the purpose of research an example of an intermodal marine terminal with its individual functional areas is presented. Finally, the literature review on research conducted on the transport processes performed in the terminal are presented in chapter 4. These processes refer to quay side and land side horizontal transport operations. Additionally, the arrangement of containers at the storage yard was investigated.

Opis:
The article presents the problems of designing intermodal terminals from the point of view of expenditures on construction and equipment as well as costs of its operation. The scope of factors to be considered at the design stage of the intermodal terminal was determined. The principles of calculation of expenditure on terminal infrastructure are presented. Based on these expenditures, the principles of calculating the cost of maintenance of equipment and labour are outlined. In addition, the practical examples of determining the cost of operation of handling equipment and labour costs are presented. The terminal carries out the functions of transhipment of intermodal transport units between means of transport, belonging to different modes of transport and the operations on these units in connection with their storage. Due to the different types of external means of transport operated in the intermodal terminal, a sufficient number of rail tracks, roads lines, storage, and handling areas should be provided. Apart from expenditures and costs, an important element in the design of an intermodal terminal is its location in the logistics network.

Opis:
Deliveries planning in transport systems is a complicated task and require taking into account a wide range of factors. Enterprises wanting to propose solutions that meet the clients’ needs and be competitive on the market must prepare their offer based on decision support systems including factors characteristic for the real process. The aim of the article is to present a concept of a decision support system based on a multi-criteria vehicle routing problem in real conditions (Real-World VRP). Taking into account the latest trends in the optimization of the delivery plan, the model includes three criteria - the cost, time and success rate of the delivery plan as a criterion relating to the quality of the delivery plan. Among other assumptions, it should be pointed out that the heterogeneous structure of the rolling stock has been taken into account, the number of which is not limited, the vehicles return to the place of origin. The travel time of the connection and the time of loading operations are random variables. The limited driver’s work time and driving time were also applied. The effect of the work presented in the article is the concept of the decision support system in the freight transport, taking into account the quality criterion of the delivery plan.

Opis:
Operational vehicle quality measures are an important element used to evaluate the performance of transport services. In practice, there are many methods involved in the operational evaluation of vehicles. They are characterized in this article. Artificial Intelligence methods, especially artificial neural networks, can also be successfully used for this purpose, and especially when deciding on quality assessment processes for machines, including motor vehicles. The use of methods to support decision-making based on facts is extremely important for the credibility and objectivity of the evaluation. These methods can also be used in relation to the use of vehicles in the assessment of transport services. The article presents the method of using artificial neural networks for the operational evaluation of vehicles used in freight transport services. The basis for the verification of the method was an experimental research carried out at a company making dairy products, cooperating with transport companies, supplying products for the production process. The results obtained from the operation of vehicles from the studied companies have confirmed, at the probability level of 99%, high efficiency of the proposed method in evaluating transport services using operational vehicle quality measures.
Eksploatacyjne miary jakości pojazdów są istotnym elementem wykorzystywanym do oceny realizacji usług transportowych. W praktyce mamy do czynienia z wieloma metodami związanymi z eksploatacyjną oceną pojazdów. Scharakteryzowano je w artykule. Metody sztucznej inteligencji, a zwłaszcza sztuczne sieci neuronowe, również mogą być z powodzeniem wykorzystane do tego celu, a zwłaszcza przy podejmowaniu decyzji w procesach oceny jakości maszyn, w tym pojazdów samochodowych. Zastosowanie metod, które pozwalają wspomagać proces decyzyjny na podstawie faktów jest niezmiernie istotne z punktu widzenia wiarygodności i obiektywności oceny. Metody te mogą być również wykorzystane w odniesieniu do eksploatacji pojazdów w zastosowaniu do oceny usług transportowych. W artykule przedstawiono metodę wykorzystania sztucznych sieci neuronowych do eksploatacyjnej oceny pojazdów wykorzystywanych w usługach transportowych towarów. Podstawę weryfikacji metody stanowiły badania eksperymentalne przeprowadzone w przedsiębiorstwie produkującym produkty mleczarskie, współpracującym z firmami transportowymi, dostarczającymi wyroby do produkcji. Uzyskane wyniki potwierdziły z 99-procentowym prawdopodobieństwem wysoką skuteczność proponowanej metody w dokonywaniu oceny usług transportowych z wykorzystaniem eksploatacyjnych miar jakości pojazdów.

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.

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.

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.

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.
