The aim of this article is to analyze the impact of new technologies on supply chain management in the Armed Forces. The supply chain is not limited to the operations related to the physical movement of goods, but also includes the management of relations with suppliers and customers. However, the supply chain management, through the integration and coordination of both information and goods flow, is a main factor of the well-developed customer service. The changes in military logistics imposed the necessity of implementation of the modern information technologies in the Polish Armed Forces. The Polish Army has adopted the Integrated Multi-level Information System of the Ministry of Defense (ZWSI RON). The article describes various technologies used in supply chain management including information, communication and automatic identification technologies. The author emphasizes that modern technologies are essential to enhance supply chain competitiveness and performance by improving the overall effectiveness and efficiency of the logistic system. Moreover, implementing of various innovative technologies shortens the time required for the fulfillment of tasks as well as reduces their labor consumption.

Opis:
Identyfikacja zwierząt, ludzi i przedmiotów stosowana była od bardzo dawna. Obecnie duże znaczenie zyskuje identyfikacja automatyczna umożliwiająca jednoznaczne rozpoznawanie obiektów przez urządzenia (automaty), przy minimalnej ingerencji człowieka. Identyfikacja obiektów wiąże się z kodowaniem danych, znakowaniem obiektów, zapisywaniem i przechowywaniem danych w bazach danych, odczytem danych przez odpowiednie urządzenia oraz wykorzystywaniem odpowiednich systemów informatycznych. Korzyści wynikające ze stosowania identyfikacji automatycznej to m.in: zwiększenie wydajności prac, obniżenie kosztów pracy, przyspieszenie obsługi klientów, możliwość identyfikacji obiektów będących w ruchu lub trudno dostępnych. Stosowana coraz częściej automatyczna identyfikacja obiektów wzbudza uzasadnione zainte-resowanie. Ogromne spektrum zastosowań, duża niezawodność, prostota i wygoda stosowania oraz miniaturowe rozmiary urządzeń, sprawiają, że identyfikacja automatyczna jest wykorzystywana coraz częściej. Cechy identyfikacji takie jak szybkość, jakość i niezawodność mają zasadnicze znaczenie dla jej masowego wykorzystywania. Jednak brak znajomości tych technologii, obawa o utratę prywatności i podejrzenia o możliwość inwigilacji dzięki wykorzystaniu automatycznej identyfikacji bez wiedzy i zgody obywateli w wielu przypadkach stanowi barierę w jeszcze powszechniejszym ich wykorzystywaniu. W pracy przedstawiono popularne obecnie technologie identyfikacji obiektów takie jak: kody kreskowe a w szczególności QR kody, technologię RFID (Radio Frequency IDentification) oraz techniki biometryczne. Wskazano liczne różnorodne obszary ich zastosowań oraz korzyści z ich wykorzystywania. Omówiono także możliwe zagrożenia dla bezpieczeństwa gromadzonych i przetwarzanych danych w tych technologiach oraz obawy obywateli przed ich stosowaniem.
Identification of animals, people and objects has been used for long time. Automatic identifi-cation, which allows for unambiguous recognition of objects by devices (machines) with minimum human intervention, has become a topic of growing importance. Identification of objects is associated with the encoding of data, object marking, saving and storing data in databases, data access with proper equipment and the use of appropriate systems. The benefits of automatic identification include: increased productivity of work, lower labour costs, faster customer service, the ability to identify moving or difficult to access objects. Automatic identification of objects, which is used increasingly often, raises legitimate interest. Huge range of applications, high reliability, the simplicity and convenience of use and miniature sizes of equipment make automatic identification being used more and more frequently. Its characteristics such as speed, quality and reliability are essential to its mass use. However, the lack of comprehension of the technology, fear of loss of privacy and suspicion about the possibility of surveillance through the use of automatic identification without the knowledge and consent of citizens is still in many cases a barrier to their widespread use. This paper presents the currently popular object identification technologies such as bar codes and, in particular, QR codes, RFID (Radio Frequency Identification) and biometric techniques. It mentions a number of different areas of their uses and benefits. Also possible threats to the security of data collected and processed with these technologies and concerns of citizens against the use of these technologies are discussed.

Opis:
Ship route planning is one of the key issues in enhancing traffic safety and efficiency. Many route planning methods have been developed, but most of them are based on the information from charts. This paper proposes a method to generate shipping routes based on historical ship tracks. The ship's historical route information was obtained by processing the AIS data. From which the ship turning point was extracted and clustered as nodes. The ant colony algorithm was used to generate the optimize route. The ship AIS data of the Three Gorges dam area was selected as a case study. The ships’ optimized route was generated, and further compared with the actual ship's navigation trajectory. The results indicate that there is space of improvement for some of the trajectories, especially near the turning areas.

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.

Opis:
The use of the Automatic Identification System (AIS) devices for ensuring the safety of navigation and the errors occurring when using AIS equipment have been the focus of a number of research studies. The users of AIS equipment installed onboard sea-going vessels are required to familiar with the proper use of the devices and potential errors that may occur. A significant problem revealed in this study is the lack of understanding of potential error sources and the necessity to eliminate such errors prior to transmission of the AIS data message reading of the errors and failure to update the data processed by the AIS system. This results in a hypothesis on the insufficient training of seafarers and their familiarisation with the AIS devices and errors. This research is aimed at increasing the safety of navigation in the Adriatic Sea, as well as other seas, i.e. better accident prevention and protection of human life and material property at sea. The results produced by the research are used as an input for creating a model for enhancing the safety of navigation when using the AIS, through additional training of the seafarers.

Opis:
It is essential to evaluate safety of marine traffic for the improvement of efficiency and safety of marine traffic. Spread of AIS makes observation of actual marine traffic more easily and faster than before. Besides, description of collision avoidance behaviours of ships are indispensable to simulate a realistic marine traffic. It is important to develop and implement an algorithm of collision avoidance corresponding to a target traffic or target area into the marine traffic simulation because actual actions for collision avoidance depend on circumstances where ships are sailing. The authors developed an automated marine traffic simulation system with AIS data. And in this paper, we proposed a series of systematic procedures for marine traffic simulation including analysing for collision avoidance behaviours using AIS data.

Opis:
This paper proposes an estimation method for ships on collision courses taking crash astern maneuvers based on a new potential area of water (PAW) for maneuvering. A crash astern maneuver is an emergency option a ship can take when exposed to the risk of a collision with other ships that have lost control. However, lateral forces and yaw moments exerted by the reversing propeller, as well as the uncertainty of the initial speed and initial yaw rate, will move the ship out of the intended stopping position landing it in a dangerous area. A new PAW for crash astern maneuvers is thus introduced. The PAW is developed based on a probability density function of the initial yaw rate. Distributions of the yaw rates and speeds are analyzed from automatic identification system (AIS) data in Madura Strait, and estimated paths of the maneuvers are simulated using a mathematical maneuvering group model.

Opis:
Optimal ship tracks computed via the VISIR model are compared to tracks recorded by the Automatic Identification System (AIS). The evaluation regards 43 tracks in the Southern Atlantic Ocean, sailed during 2016-2017 by different bulk carriers. In this exercise, VISIR is fed by wave analysis fields from the Copernicus Marine Environment Monitoring Service (CMEMS). In order to reproduce vessel speed loss in waves, a new methodology is developed, where kinematic information from AIS is fusioned with wave information from CMEMS. Resulting VISIR tracks are analyzed along with AIS tracks in terms of their topological features and duration. The tracks exhibit quite diverse topological shapes, including orthodromic, loxodromic, and other paths with complex and dynamic diversions. The distribution of AIS to VISIR track durations is analyzed in terms of several parameters, such as the AIS to VISIR track length and their Fréchet distance. Model features of VISIR affecting the results are discussed and future developments suggested by the results are outlined.

The traffic density is a basic characteristic of marine traffic for some navigational area. In the case of narrow channels such as Strait of Split (Splitska vrata), apart from the traffic density, the number of simultaneous ship passages is also important as well as ships characteristics. Based on such data, additional navigational safety guidelines and regulations may be planned for the observed area. The purpose of this research is to determine the number of simultaneous ship passages via Strait of Split for a certain period of time. Collected AIS data in SPNMEA format was decoded by AIS Decoder online program to csv file. For five randomly selected days in the summer period, based on AIS data, the number of simultaneous ship passages was determined and ships information presented.

Opis:
This paper considers the degree of competition among small and medium-sized container ports located in a multi-port gateway region. The level of port competition is evaluated by means of an analysis of the revealed preferences in the port-calling pattern of container feeder vessels deployed on their various links and routes. Unit of analysis is feeder vessel sailing legs and ports stays at/between adjacent container ports. At these ports’ terminals, ships are moored and loading and unloading of containers are performed. The vessel movement data is provided by the Automatic Identification System (AIS). A study of the principal container ports in the Oslo Fjord area is performed, measuring the actual container feeder traffic during the year of 2015. It is demonstrated to which extent ports in the Oslo Fjord region are acting as substitutes, and to which extent they are functioning more as a complement to each other.
