A study of Intelligent Transport Systems (ITS) in Dublin Port in conjunction with the Intelligent Transport for Dynamic Environment (InTraDE) Project

In the last four decades the container as an essential part of a unit load-concept has achieved authentic importance in international sea freight transportation. With ever increasing containerization the number of port container terminals and competition among them has become quite remarkable. Port container operations are nowadays unthinkable without effective and efficient use of Intelligent Transport Systems (ITS) (Steenken & Stahlbock, 2004). The main problem in handling increasing levels of cargo is managing the internal traffic and optimizing space inside smaller and medium sized ports. A gap exists between automated cargo handling equipment that is suitable for use in the larger container terminals such as Rotterdam and its suitability in smaller terminals such as Dublin. A new generation of cargo handling technology has been designed in the form of an Intelligent Autonomous Vehicle (IAV). The IAV is a clean, safe, intelligent vehicle which will contribute to improving the traffic management and space optimization inside confined space by developing a clean, safe and intelligent transport system. This technology has been designed and developed as part of the ‘InTraDE’ (Intelligent Transport for Dynamic Environment) project to which the research has contributed. By using ITSs, logistics operations could be improved by enhancing the exchange of information and real-time status updates regarding different business operations in different modes of transportation (Schumacher et al., 2011). Maritime transport has recently gained increased attention, especially in connection to the building and further development of ITS (Pietrzykowski, 2010). This research looks at the main logistic processes and operations in port container terminals. It discusses the extent to which the terminal shipping operators in Dublin Port currently meet the demands of their customers and whether the introduction of ITS could enhance the efficiency and productivity of such services

Rescheduling policies for large-scale task allocation of autonomous straddle carriers under uncertainty at automated container terminals

This paper investigates replanning strategies for container-transportation task allocation of autonomous Straddle Carriers (SC) at automated container terminals. The strategies address the problem of large-scale scheduling in the context of uncertainty (especially uncertainty associated with unexpected events such as the arrival of a new task). Two rescheduling policies-Rescheduling New arrival Jobs (RNJ) policy and Rescheduling Combination of new and unexecuted Jobs (RCJ) policy-are presented and compared for long-term Autonomous SC Scheduling (ASCS) under the uncertainty of new job arrival. The long-term performance of the two rescheduling policies is evaluated using a multi-objective cost function (i.e., the sum of the costs of SC travelling, SC waiting, and delay of finishing high-priority jobs). This evaluation is conducted based on two different ASCS solving algorithms-an exact algorithm (i.e., branch-and-bound with column generation (BBCG) algorithm) and an approximate algorithm (i.e., auction algorithm)-to get the schedule of each short-term planning for the policy. Based on the map of an actual fully-automated container terminal, simulation and comparative results demonstrate the quality advantage of the RCJ policy compared with the RNJ policy for task allocation of autonomous straddle carriers under uncertainty. Long-term testing results also show that although the auction algorithm is much more efficient than the BBCG algorithm for practical applications, it is not effective enough, even when employed by the superior RCJ policy, to achieve high-quality scheduling of autonomous SCs at the container terminals. © 2013 Elsevier B.V.

The synergistic effect of operational research and big data analytics in greening container terminal operations: a review and future directions

Container Terminals (CTs) are continuously presented with highly interrelated, complex, and uncertain planning tasks. The ever-increasing intensity of operations at CTs in recent years has also resulted in increasing environmental concerns, and they are experiencing an unprecedented pressure to lower their emissions. Operational Research (OR), as a key player in the optimisation of the complex decision problems that arise from the quay and land side operations at CTs, has been therefore presented with new challenges and opportunities to incorporate environmental considerations into decision making and better utilise the ‘big data’ that is continuously generated from the never-stopping operations at CTs. The state-of-the-art literature on OR's incorporation of environmental considerations and its interplay with Big Data Analytics (BDA) is, however, still very much underdeveloped, fragmented, and divergent, and a guiding framework is completely missing. This paper presents a review of the most relevant developments in the field and sheds light on promising research opportunities for the better exploitation of the synergistic effect of the two disciplines in addressing CT operational problems, while incorporating uncertainty and environmental concerns efficiently. The paper finds that while OR has thus far contributed to improving the environmental performance of CTs (rather implicitly), this can be much further stepped up with more explicit incorporation of environmental considerations and better exploitation of BDA predictive modelling capabilities. New interdisciplinary research at the intersection of conventional CT optimisation problems, energy management and sizing, and net-zero technology and energy vectors adoption is also presented as a prominent line of future research

Analysis of the maritime logistic system in Chile and the design of a parametric model to decision making

The internationalisation of investments and the globalisation of the markets have created a high level of competition among manufacturing and services companies which has transcended the competition among nations. In this environment, quality information and exact timing are the sole answers for generating comparative and competitive advantages with respect to other manufacturers and providers. Inspired by these challenges, Latin American countries have searched for ways to increase and diversify their exports in order to heighten their trade balance surpluses. This, in turn, helps them to overcome their debt problems and gain access to a better quality of life. With these criteria in mind, these countries have begun to join the economic aperture and globalisation processes. United by their common ethnic heritage, they are driven by the growing need to co-ordinate national and regional decisions in order to achieve a harmonic community development. The efficiency principle imposed by the present international trade scenario requires extreme attention to detail in the administration of production costs and in placing products on the market. Because a product's success is highly sensitive to cost and distribution methods, maritime transport and its associated systems require very specific management techniques. Those management techniques must take into account that as transport is a service it gives added value to the cargo. Thus, the management model, costs involved, planning processes, and area policies are topics of vital importance for achieving these nations' development objectives. The design of specific policies, both operational as well as for development (investments), should comply with certain minimum conditions. The resulting policies should satisfy integrally and harmoniously the requirements the State establishes in its general National Development Strategy. This strategy considers factors of monetary and trade uncertainty. States must be particularly careful to interpret changes, tendencies, circumstances and difficulties which emerge in the international markets they serve, correctly. Therefore, the purpose of this study is to analyse the existing maritime transport logistic system in Chile, beginning with the history of ports and economic development. Subsequently, this study will analyse all relevant information related to logistics and the lessons learnt during the process of modernization. For analytical purposes, the study establishes an evaluation area which has been represented by a "graph" built up from nodes and links.These symbolise the complex network of port systems, hinterlands, roads, railways and coastal shipping. Likewise, the links and nodes have direction, intensity and values that the study intends to describe and evaluate. Moreover, hinterlands are not as exclusive as they were before. Consequently, most of the port systems face a very competitive market in offering services for international hinterlands/foreland. Therefore, this thesis will conclude that at least some Latin American countries establish land bridges between them. There have been some studies about the land bridges, "inter-oceanic corridors" or "integration corridors" options in South America.The Pacific Ocean Basin and the APEC countries represent a huge market for those Atlantic countries which have products to export and import from that vast area of the globe. The existence of the main industrial site of South America running from the Atlantic side of South America to the Pacific Coast, which forms an "Industrial Banana", is the foundation of a massive demand to and from both coasts. The study evaluated the logistics system through different criteria, such as logistics, physical capacities, and economic, social, environmental and political considerations. Having established these criteria, the researcher can better evaluate the relevant parameters and variables to consider in the design of the parametric model.La internacionalizacion de las inversiones y la globalizacion de los mercados, han creado un alto nivel de competitividad entre los proveedores de manufactura o de servicios, lo que trasciende a la competitividad entre las naciones. En este escenario, la informacion de calidad y respuesta en tiempo real son la respuesta para generar ventajas comparativas y competitivas respecto de otros productores y proveedores. Inspirados en estos cambios, los paises Latinoamericanos han buscado formas como aumentar y diversificar sus exportaciones, con el proposito de incrementar sus balanzas comerciales. Esto les ayuda a sobrellevar sus problemas de deuda, accediendo a mejor calidad de vida. Con estos criterios en mente, los paises de la Region han accedido a los procesos de apertura economica y globalizacion de los mercados. Unidos por la herencia etnica comun, ven una creciente necesidad por la coordinacion de sus decisiones nacionales y regionales, de manera de alcanzar el desarrollo comun de manera harmonica. Los principios de eficiencia impuestos por el presente esquema de comercio internacional, requiren de una atencion especial en la gestion de los costos de produccion y en la colocacion de los productos en los mercados. Considerando que el exito del producto es sensible a su costo, los sistemas de distribucion y logistica requiren de tecnicas especificas de gestion. Por ello, los modelos de gestion, costos, procesos de planificacion y politicas sectoriales son de vital importancia para alcanzar los objetivos nacionales de desarrollo. El diseno de politicas sectoriales, tanto operacionales como de desarrollo (inversiones), deberian cumplir con los minimas condiciones para lograr su objetivo pais. Las politicas resultantes debieran satisfacer de manera integral y harmonica, los requirimientos que el Estado ha establecido en su Estrategia Nacional de Desarrollo. Dicha estrategia debe incluir las incertidumbres monetarias y de commercio. Los Estados deben ser particularmente cuidadosos para interpretar correctamente los cambios, tendencias, circunstancias y dificultades que emergen de los mercados internacionales que ellos sirven. Por lo indicado anteriormente, el proposito de esta tesis es analizar el sistema de logistica maritima en Chile, comenzando con la historia de sus puertos y desarrollo economico, posteriormente el analisis de la informacion relevante a logistica y las lecciones aprendidas durante el proceso de modernizacion economica. Con propositos analiticos, el estudio determino una zona fisica de evaluacion que esta representada por la "teoria de grafos". Esta simboliza la compleja red de puertos, hinterlands, caminos, ferrovias y transporte maritimo costero. Los nodos y sus enlaces tienen direccion, intensidad y valores que el estudio pretende evaluar y dimensionar. Mas aun, en la actualidad el hinterland de los puertos ha dejado de ser exclusivo, consecuentemente, los sistemas portuarios enfrentan una agresiva competencia para ofertar servicios a sus hinterland/foreland, por lo cual algunos paises latinoamericanos construyeron "puentes terrestres" entre ellos, el estudio indica algunas opciones de "puentes terrestres", "corredores inter-oceanicos" o "corredores de integracion" identificados en America del Sur. La cuenca del Pacifico y los paises APEC representan un mercado enorme para los paises de la costa Atlantica. La existencia de la principal area industrial de Sudamerica se configura entre el Atlantico y Pacifico, forma lo que el autor denomina como la "Banana Industrial", lo que origina una enorme demanda en los dos sentidos. El estudio evalua los sistemas desde diferentes criterios, tales como: sus capacidades fisicas y logisticas, sus consideraciones economicas, politicas, sociales, y medio ambientales. Una vez establesidos los criterios, el investigador puede identificar y evaluar de mejor forma los parametros y variables a considerar en el diseno del "modelo parametrico".Postprint (published version

Focusing on the case analysis of advanced smart ports

학위논문(석사) -- 서울대학교대학원 : 행정대학원 글로벌행정전공, 2023. 2. Lee, Soo-young.본 연구에서는 최근 각광받고 있는 스마트 항만의 개념과 항만 경쟁력과의 관계를 고찰해 보고, 선진 스마트 항만에 대한 다각적인 분석을 통해 우리나라 스마트 항만 발전 방향에 대한 시사점을 도출하고자 하였다. 이를 위해 A. Molavi 외의 연구에서 확립된 스마트 항만 평가 척도의 4가지 측면, 운영측면(Operation), 환경측면(Environment), 에너지 측면(Energy), 그리고 안전과 보안 측면(Safety & Security)의 분석틀을 활용하여 스마트 항만 개발과 발전에 가장 앞선 네덜란드의 로테르담 항만과 독일의 함부르크 항만의 정책 분석을 시도하였다. A. Molavi 외의 연구는 측정 가능한 스마트화 지수를 발전시켜 각 항만의 스마트화 정도를 가늠하고 장단점을 파악할 수 있게 하기 위한 취지에서 개발되었다. 하지만 본 연구에서는 스마트 항만의 평가 척도를 활용하되 질적인 분석으로 접근하여 정책 활용 측면에서 유용한 시사점을 도출하는데 목적을 두었다. 또한 동일한 틀을 활용하여 현재 부산 컨테이너 터미널의 스마트 항만 발전 계획을 분석하고 발전방향 설정에 도움을 주고자 하였다. 우선 운영 측면에서 선진 스마트 항만들은 항만 내 하역 전 과정의 완전 자동화를 달성하였고, 이에 그치지 않고 항만 내 모든 과정을 4차 산업혁명의 첨단 기술들을 활용하여 무인화와 효율화를 추구하였다. 이 과정에서 A.I, IoT, 블록체인 등 4차 산업혁명의 핵심 기술들을 적극 활용하여 항만의 전체적인 모습을 변화시켜 가고 있으며, 비용절감과 생산성 증대 등 직접적인 효과뿐만 아니라 글로벌 물류의 핵심 구심점으로써 스마트 항만의 가능성을 발전시켜 나가고 있다. 이를 통해 항만 경쟁력 향상은 물론 물류 포털로써의 지위를 선점하기 위한 경쟁도 심화되고 있다. 환경 측면에서는 친환경 항만에 대한 관심이 증대되고 있다. 항만은 더 이상 도시와 분리되어 존재하는 독립된 영역이 아닌, 인접 도시 주민들과 상호 영향을 주고받으며 발전하는 호혜적인 관계를 구축해야 한다는데 공감대가 형성되고 있다. 이를 위해 그동안 항만 활동을 통해 야기되었던 환경 오염 문제를 줄이고 지역사회에 기여하기 위한 노력들이 활발히 진행되고 있다. 전력에 기반한 친환경 하역장비로 대체하고, 선박의 연료를 친환경 연료로 전환하는 노력이 진행 중이다. 항만 내 유휴부지를 활용해 신재생에너지를 발전하고 인근 지역에 공급하는 방안과, 항만의 환경 문제를 IoT 기술을 활용하여 실시간으로 감시하고 공유하는 시스템을 구축하여 항만의 지속 가능한 발전을 의도하며 탄소 중립 사회로의 진전에 중요한 역할을 자처하고 있다. 에너지 측면에서는 스마트 항만이 미래 수소 사회의 핵심 공급 기지가 될 전망이다. 해상 물류와 육상 물류가 결합되는 기능적 이점을 활용하여 수소의 생산과 저장, 분배 등 수소 경제의 핵심 인프라를 항만 내 구축하고 항만 기능과의 결합을 시도하고 있다. 이를 위해 선진 항만들은 대규모 파이프 라인을 건설하는 프로젝트들을 진행하며 미래를 준비하고 있다. 안전과 보안 측면에서는 항만이 첨단 기술 활용의 경연장이 되고 있다. 항공 및 해상, 수중 드론 등 첨단 장비들을 활용하여 드넓은 항만을 가상 현실세계인 트윈 타워에 이식하고 인공지능에 의한 실시간 관리 감독이 가능한 시스템이 구축되고 있다. 항만 내 하역작업의 무인화는 안전사고의 위험을 획기적으로 줄일 수 있을 뿐만 아니라, 사각 지대가 없는 관리 감독도 가능해져 항만 내 재난사고와 밀입국 등의 문제를 근본적으로 변화시킬 것으로 기대되고 있다. 하지만 선진 스마트 항만에서 추구하는 근본적인 방향은 세계 물류의 핵심 포털을 구축하는 것이며 이를 위해 항만의 역할은 기존의 지역적인 한계를 넘어 기능적으로 그리고 물리적으로 팽창하고 있다. 우리나라의 경우 일찍이 자동화 항만의 발전을 시작한 유럽 항만은 물론 인근 중국과 싱가포르의 자동화 항만과 비교해도 뒤쳐지고 있는 것이 현실이다. 이를 만회하기 위해 중앙 정부 차원에서 스마트 해상물류체계 구축 전략을 수립하고 2030년 스마트 항만의 본격적인 운영을 계획하고 있다. 하지만 본 계획은 전반적인 물류 기능 중 하위 요소로 스마트 항만을 인식하고 있으며, 이는 스마트 항만을 자동화 항만이라는 좁은 측면에서만 바라보고 있는 것으로, 항만의 미래 잠재력에 대한 선진 항만들의 인식과는 큰 차이가 있다고 하겠다. 또한 스마트 항만의 발전 과정에서 민간 기업과 항만 이해관계자들이 적극적으로 참여하고 협력하여 스마트 항만의 모습을 그려가는 선진 항만과는 달리 우리나라의 경우 여전히 정부 주도 발전 방식을 고수하고 있으며, 가장 주도적인 역할을 해야 할 항만 공사들의 역할이 미미한 것은 한계라고 하겠다. 그리고 향후 탄소 중립 사회로의 이행의무 등 환경적인 문제와 친환경 에너지로의 전환이 중요시되고 있는 시점에서 이에 대한 근본적인 전환계획이나 항만의 새로운 역할에 대한 고민이 부족한 것도 비교 연구를 통해 도출할 수 있었다. 유럽의 항만들과는 달리 수소 경제로의 이행에 있어 항만의 핵심적 역할이 빠져 있다는 것은 스마트 항만에 대한 인식 부족에서 비롯된 것으로 보이며 이에 대한 정책적 개선이 필요한 것으로 보인다.This study examines the relationship between the concept of smart ports and port competitiveness, which have recently been in the spotlight, and attempts to derive implications for Korea's smart port development direction through various analysis of advanced smart ports. To this end, this research attempted to analyze the policies of Rotterdam Port in the Netherlands and Hamburg Port in Germany, which are most advanced in smart port development and development, using the analysis framework of four smart port evaluation measures established in A. Molavi et al. In terms of operation, advanced smart ports achieved complete automation of the entire loading and unloading process in the port, and not only this, but all processes in the port were pursued for unmanned and efficient use of the advanced technologies of the 4th Industrial Revolution. In terms of the environment, interest in eco-friendly ports is increasing. There is a consensus that ports should no longer be independent areas that exist separately from cities, but should establish reciprocal relationships that interact and develop with residents of neighboring cities. In terms of energy, smart ports are expected to become a key supply base for the future hydrogen society. Taking advantage of the functional advantages of combining marine logistics and land logistics, the core infrastructure of the hydrogen economy, such as hydrogen production, storage, and distribution, is built in ports and attempted to combine them with port functions. In terms of safety and security, ports are becoming a competition for the use of advanced technology. Using high-tech equipment such as aviation, sea, and underwater drones, a system that allows real-time management and supervision by artificial intelligence is being established by transplanting a wide port into a virtual reality twin tower. In the case of Korea, the reality is that it is lagging behind not only European ports that started the development of automated ports early but also automated ports in neighboring China and Singapore. To make up for this, the central government has established a "smart maritime logistics system construction strategy" and plans to operate smart ports in earnest in 2030. However, this plan recognizes smart ports as a sub-factor of the overall logistics function, which only looks at smart ports in the narrow aspect of automated ports, which is very different from advanced ports' perceptions of the future potential of ports. In addition, unlike advanced ports in which private companies and port stakeholders actively participate and cooperate in the development of smart ports, Korea still adheres to the government-led development method, and the role of port authorities to play the most leading role is insignificant. In addition, at a time when environmental problems such as the obligation to transition to a carbon-neutral society in the future and the transition to eco-friendly energy are becoming important, this comparative study was able to derive the lack of concern about the fundamental transition plan or the new role of ports. Unlike ports in Europe, the absence of a key role in the transition to a hydrogen economy seems to stem from a lack of awareness of smart ports, and policy improvements are needed.Chapter 1.

Shipping Digitalization and Automation for the Smart Port

Shipping, like most industries, is undergoing a digital transformation process which influences existing business models and operational practices, in a multifaceted way. Today, the shipping business context has been changing to incorporate further social demands, environmental, innovation and sustainability priorities, into fundamental shipping strategies, while taking advantage of technological advancements. In the era of Industry 4.0, which constitutes a recent evolution of advanced communications and information technologies and further promotes sustainable, human-centric, and resilient business development strategies, shipping and port entities need to embrace a broader perspective and a deeper understanding of various elemental technologies, namely: Artificial Intelligence, Blockchain, Cloud Computing, Big Data, and Physical Internet, in addition to core maritime logistics matters. This chapter proposes a descriptive framework of shipping digitalization and port automation, while providing a review of related technologies and business approaches, also international initiatives, for automation in global ports. Hence the chapter offers insights for business practitioners to steer through the current challenging global environment, also for policy makers to gain a more informed understanding of maritime logistics developments, towards necessary coordination and oversight mechanisms implementation

Control of free-ranging automated guided vehicles in container terminals

Container terminal automation has come to the fore during the last 20 years to improve their efficiency. Whereas a high level of automation has already been achieved in vertical handling operations (stacking cranes), horizontal container transport still has disincentives to the adoption of automated guided vehicles (AGVs) due to a high degree of operational complexity of vehicles. This feature has led to the employment of simple AGV control techniques while hindering the vehicles to utilise their maximum operational capability. In AGV dispatching, vehicles cannot amend ongoing delivery assignments although they have yet to receive the corresponding containers. Therefore, better AGV allocation plans would be discarded that can only be achieved by task reassignment. Also, because of the adoption of predetermined guide paths, AGVs are forced to deploy a highly limited range of their movement abilities while increasing required travel distances for handling container delivery jobs. To handle the two main issues, an AGV dispatching model and a fleet trajectory planning algorithm are proposed. The dispatcher achieves job assignment flexibility by allowing AGVs towards to container origins to abandon their current duty and receive new tasks. The trajectory planner advances Dubins curves to suggest diverse optional paths per origin-destination pair. It also amends vehicular acceleration rates for resolving conflicts between AGVs. In both of the models, the framework of simulated annealing was applied to resolve inherent time complexity. To test and evaluate the sophisticated AGV control models for vehicle dispatching and fleet trajectory planning, a bespoke simulation model is also proposed. A series of simulation tests were performed based on a real container terminal with several performance indicators, and it is identified that the presented dispatcher outperforms conventional vehicle dispatching heuristics in AGV arrival delay time and setup travel time, and the fleet trajectory planner can suggest shorter paths than the corresponding Manhattan distances, especially with fewer AGVs.Open Acces
