    Opis:
    The paper presents the problem of designing transportation system for goods distribution with usage of multicriteria decision supporting method. The general characteristic of transportation system as an element of distribution system was presented. Moreover, the distribution system was identified as a one of the most important elements of supply chain which aims in making products available in place and time matching client needs. In further part the problem was mathematically formalized to optimization task. Analyzing the problems of modeling conveying system forces claim that decisions taken within area of transport organization consist in solving complex decision problems. Complexity follows from the demand of best decision according to many aspects. Solution must ensure othe best realization of all partial criteria (aims) taken into account during decision making process. The article contains characteristics of methods of multicriteria evaluation with regard to short literature review. The emphasis was placed on ELEKTRA and MAJA methods which can be applied in the evaluation of complex decision problems in transportation systems. The last part of the article is verifies of presented issues by tneans of numerical experiment.

    Opis:
    This paper presents results of research on the need for transportation services and their forms. Based on a conducted survey it might be stated that 59.04% of farmers see a need for transportation service and the share in answers increases along with an increase in age of the respondents (50% for group A and 68.18% fro group C). 46.94% of respondents point to time savings as the most common reason for such service demand. The average of service users is 48.80%, but this number increases along with an increase in farmers’ age. The most frequent justification for the use of transportation services is time efficiency (increase in number of users along with an increase in age) and cost efficiency (there is however an opposite correlation). 43.98% of farmers are service providers and their main reason is additional income, with a decreasing tendency along with an increase in age. Combination of supply services and sales with transportation services performed by compa-nies who supply and purchase products is the most frequently quoted service model, with the average of 36.73% and a decrease in interest in such ventures along with an increase in farmers’ age is visible. Another model is neighbour-to-neighbour services, with an average of 30.73% and a significant increase along with an increase in farmers’ age.
    Przedstawiono wyniki badań dotyczących potrzeby usług transportowych na terenach wiejskich i ich modelu. Na podstawie przeprowadzonych badań można stwierdzić, że 59,04% rolników widzi potrzebę usług transportowych i w miarę wzrostu wieku właściciela liczba odpowiedzi rośnie (grupa A 50% i grupa C 68,18%). Oszczędność czasu (46,94% odpowiedzi) to najczęstszy powód zapotrzebowania na usługi. Przy średniej 48,80% korzystających z usług w miarę wzrostu wieku rolnika liczba korzystających rośnie. Podstawowym powodem korzystania z usług jest oszczędność czasu (wzrost korzystających wraz ze wzrostem wieku), drugi powód to taki, że usługi są tańsze (tendencja odwrotna}. 43,98% rolników jest usługodawcami, a główny powód to dodatkowy zarobek - widoczna tendencja malejąca w miarę wzrostu wieku rolnika. Łączenie zaopatrzenia i sprzedaży produktów z transportem wykonywanym przez firmy zaopatrujące w środki i zakupujące produkty, to najczęściej wymieniany model obsługi (36,73% odpowiedzi) ma coraz mniejsze zainteresowanie w miarę wzrostu wieku rolnika. Drugi z kolei model to usługi sąsiedzkie (30,73% odpowiedzi), na który występuje znaczny wzrost zainteresowania w miarę wzrostu wieku rolnika.

    Opis:
    In Japan, it is becoming difficult to move freight long distances using only trucks, owing to a shortage in truck drivers. In this context, there is a tendency to also actively utilize ferries or roll-on/roll-off (RORO) ships. Intermodal freight transport uses two or more suitable modes of transport from the origin of goods to the destination. In order to promote intermodal freight transport, it is necessary to analyze factors such as the characteristics of transported goods, transportation services and fares, and lot sizes. In this study, we focused on ferries and RORO ships in Japan, and attempted to identify cargoes transported using different modes of transport, based on the net freight flow census. In conclusion, high volumes of “agricultural and fishery products,” “metal machinery,” “chemical industrial,” “light industrial,” and “miscellaneous manufacturing products” can be transported using ferries or RORO ships. Specifically, there is a tendency that products are segregated by transportation mode such as a truck, or a ferry and a RORO ship.

    Opis:
    More and more attention become to Transport Company’s functioning efficiency due to growing of goods’ nomenclature and specific requirements for their service. Existing scientific and practical approaches to managing of transportation process consider separate service of each contract individually. Up-today requirements for transportation services complicate such evaluation. These requirements primarily include transportation frequency and volumes variation in each logistics system due to seasonal consumption of material flows. Different seasonality leads to irrational use of vehicles and decrees of their efficiency. All this gives rise to the mechanism of compatible transportation service of numerous logistics systems and their material flows by any enterprise. The paper consist of next sections the analysis of scientific framework and methods on the transportation services, fleet estimation, efficiency evaluations, analysis of requirements of transportation services; Mechanism of joint transportation services; Modelling of transportation services in logistics systems, where joint efficiency estimation of transportation functioning and logistics system and conclusions. The proposed methods and tools in the complex allow to identify and evaluate the effectiveness of the joint motor transport service of logistic systems by own and hired vehicles compared to the separate on the basis of performance indicators, which vary depending on the technological parameters: transport distances, runway usage factor, cargo class, load capacity of motor vehicles . The offered approach will reveal: regularities of change of indicators of efficiency of variants of the joint motor transport service between the traditional approach (a separate calculation of efficiency for each logistics system) and the proposed (calculation of compatible services), which allows to determine the equivalent cost of transport services during motor transport maintenance of material flows. The calculations confirm the effect of use compared to the separate combined transportation of material flows, which will be shown in reducing the required amount of vehicles by 31,8% and increasing efficiency from 5% to 60%, depending on the initial values of the transportation services parameters. The results of the project can be used in the formation of a freight vehicle fleet of any enterprise that is faced with the issue of hiring transport or have its own, PL providers, transport companies, and others.

    Opis:
    Formation of rational delivery routes is the main way to increase the effectiveness of client services for freight forwarding companies. The main part of the requests for transport services comes from occasional (non-constant) clients. The set of those requests forms a stochastic flow. For stochastic requests flow, the delivery routes are formed in the process of the requests receipt. Therefore, the standard approaches for merging of requests from multiple clients into routes, based on linear programming techniques, cannot be used in such conditions. An algorithm of formation under the stochastic demand conditions of such delivery routes, which allow servicing of two or more shippers, is proposed in the paper. The author has developed a specialized software to support decisions made by dispatchers of forwarding companies.

    Opis:
    The process of monitoring vehicle traffic and detecting traffic incidents and traffic obstructions requires access to information from sensors located at various points of monitoring and data acquisition systems constituting elements of contemporary Intelligent Transportation Systems (ITS). Unmanned aerial vehicles (UAVs) are increasingly becoming an element of ITS used in reconnaissance, preventive or rescue operations. Ensuring the efficiency of transportation in conditions of increased traffic requires providing users with multimedia information about: meteorological conditions prevailing on roads, traffic, current events and difficulties, and information on the availability of parking spaces. In each of the mentioned cases, the reliability and quality of information provided with the use of UAVs is an extremely important issue. Therefore, the provision of video surveillance services with a predictable level of quality and reliability is an important challenge for UAVs practical implementations. Thus, the fundamental research problem considered in the publication is the analysis of the impact of environmental and technical parameters on the quality and reliability of the UAVs video monitoring service provided in a real operating environment.

    Opis:
    The economic and social impact of the waterborne sectors in Europe cannot be overstated, employing directly more than 3 million people and generating a turnover of about €250 billion representing more than 1% of the EU’s GDP. In order to maintain its leadership and competitiveness, Europe must take advantage of new market opportunities and address these challenges by means of focused research, development and innovation. In recent years the impact of digital technology and relevance of geospatial information has been increasingly felt across the whole maritime community bridging waterborne and coastal activities. The challenge for the maritime and marine science communities is to accelerate the transformation of the maritime sector into one that is able to exploit market-led opportunities and create high value added outputs that fully embraces technological and scientific advances. e-Maritime offers itself as the enabling framework.

    Opis:
    The article discusses the theoretical principles of statistical research with regard to the national market of logistics services during wartime. The system of statistical indicators of the research of the logistics services market is structured through the allocation of separate blocks of indicators by priority of their estimation in war conditions. The market of logistics services of Ukraine is characterised by selected blocks of indicators. The paper identifies the main structural changes that occurred due to the hostilities faced by the country. Moreover, the authors determine the main factors influencing the functioning of the analysed market during war, as the statistical study of these factors is considered necessary for the transformation and development of logistics services. It is substantiated that taking into account such statistical indicators as the level and availability of logistics infrastructure, security, the human factor and changes in legislation are likely to result in a new alternative direction of logistics routes and contribute to the development of the logistics services market in general. The authors proposed the construction of a centralised electronic service (or several services) with the purpose of consolidating information about the logistics infrastructure. The software system should offer the option of an operational interactive visualisation.

    Opis:
    In the aftermath of the sinking of the US-flagged containership El Faro in October 2015, one of the U.S. National Transportation Safety Board’s (NTSB) recommendations was for the National Oceanic and Atmospheric Administration (NOAA) to explore increasing the collection of weather data from ships in order to improve the weather forecast products that they distribute. Currently NOAA runs the Voluntary Observing Ship (VOS) program, where ships voluntarily submit weather observations to NOAA. However, only a small fraction of the thousands of vessels sailing worldwide participate in this program, and VOS weather observations are submitted infrequently, typically four times per day via a mainly manual process. One method being explored to automate and increase the frequency of data submittal is by using the existing Automatic identification System (AIS) equipment installed aboard vessels. Most commercial ships (in particular those subject to the International Maritime Organization's (IMO) Safety of Life and Sea (SOLAS) convention) have a Class A AIS transceiver installed to comply with mandatory carriage requirements. Many vessels not required to carry AIS equipment voluntarily install AIS transceivers (either Class A or B). All of these AIS transceivers (except for the Class B “CS”) can be used to transmit an AIS message 8 (broadcast binary message) by sending the transceiver an appropriately formatted NMEA sentence (BBM). Weather data can be embedded in an AIS application-specific message (ASM) carried by the AIS message 8 and automatically transmitted by the ship. This transmission can be received by terrestrial AIS stations (when in range) or by satellite AIS receivers. The AIS weather data can then be converted into the appropriate format and forwarded to the weather forecasting offices for use in models and weather predictions. This data may also be of use to other researchers monitoring climate change or other environmental factors. By leveraging this existing base of AIS transmitters, the volume of weather data being sent to weather forecast offices and others could be greatly increased. The U.S. Army Corps of Engineers (USACE) and U.S. Maritime Administration (MARAD) have been exploring the feasibility of this concept. Following a simple bench test performed by Alion Science in September 2018, an initial proof-of-concept was tested aboard the MARAD vessel Cape Wrath while moored in Baltimore in October 2018. After this successful demonstration, a prototype was installed on the Massachusetts Maritime Academy training ship TS Kennedy during her training cruise Jan-Feb 2019. During this cruise, the AIS equipment aboard the ship transmitted weather data at 3-minute intervals. Several different ASM formats were tested, including two developed specifically for this test to improve satellite reception. This report will discuss the concept, the demonstrations, and the results to date including the efficacy of the various ASM formats.
