Abstract: ABSTRACT Abstract of thesis entitled Scheduling the Landside Operations of a Container Terminal Using a Fuzzy Heuristic Submitted by Ge Ya For the Degree of Master of Philosophy at the University of Hong Kong in August 2006 Modern container terminals in a globally competitive market must constantly respond to high expectations from their customers. At the same time, intensive capital investment in terminal resources requires high productivity to reduce unit operational costs. Facing pressure from both competitors and customers, container terminals need to develop effective ways of planning their operations in order to strike an optimum balance between better customer service and higher terminal productivity. Trucks and yard cranes are the most commonly used types of landside equipment for handling containers at port container terminals. This study aims at developing an effective and efficient method for scheduling their operations to support the discharging and loading of containers at the quayside. In particular, it considers how to minimize vessel tardiness (a common customer service performance measure) and how to maximize the quay crane handling rate (a typical measure of a container iterminal's productivity). Unlike most previous studies, this study considers the interaction between the operations of trucks and yard cranes. A schedule that takes this interaction into consideration can optimize the overall performance of the terminal instead of just the performance of a limited sphere of operations performed by a single equipment type. In order to react to various changes and random events occurring in the dynamic operating environment, the real-time formulation of schedules is required. It is noted that finding the optimal solution to the scheduling problem is computationally intractable. This study proposes a fuzzy heuristic for solving the scheduling problem. The heuristic comprises two key scheduling schemes (Fuzzy 1 and Fuzzy 2) to solve the scheduling problem for each type of landside equipment. The two scheduling schemes are applied to determine the priorities of all possible jobs for a scheduled equipment type by considering a set of operational factors crucial to the terminal performance. The technique of fuzzy-logic is used to construct the implementation function for the scheduling schemes and to model the trade-off among the factors considered. The weighting coefficients employed in each scheme are treated as a user input and can be determined based on scheduling objectives or customers' needs. To evaluate the effectiveness of the proposed fuzzy heuristic, an extensive simulation experiment is conducted to compare the performance of the fuzzy heuristic with that of 4 priority-based scheduling rules. The simulation results show that the fuzzy heuristic outperforms the four scheduling rules on both performance measures and can generate effective schedules in a very short time.

Book excerpt: 1. 1 Motivation and Scope of Research Container terminals in seaports constitute interfaces between sea and land tra- port of goods in global transport chains. These logistics facilities face an increasing demandof service capacity,as is re ected by a tremendousgrowthin the worldwide container transshipments per year. For example, the top 20 terminals in the world showed an average relative increase of 14% with respect to the number of handled container units from 2006 to 2007, see Port of Hamburg Marketing (2008). In spite of this development, competition is high among container terminals within the same region. A terminal’s customers, rst and foremost the vessel op- ators, expect a high level of service quality where reliability is one of the most importantdimensions,seeWiegmansetal. (2001). Regardingtheserviceofavessel, reliability means to realize all transshipment operations within its projected service time interval. The reliability of terminal operations impacts the reliability of v- sels in meeting their liner schedules. According to Notteboom (2006) unexpected waiting times of vessels before berthing and unexpected low transshipment prod- tivity at terminals are responsible for about 86% of liner schedule disturbances, see Fig. 1. 1. Currently, many terminal operators counteract this situation by extending their transshipment capacities. They build new terminals or enlarge existing ter- nals and purchase new or upgrade existing equipment. Ilmer (2005) provides an overview of current projects for building terminal capacity in northern Europe.

Book excerpt: The present book includes a set of selected extended papers from the fifth International Joint Conference on Computational Intelligence (IJCCI 2013), held in Vilamoura, Algarve, Portugal, from 20 to 22 September 2013. The conference was composed by three co-located conferences: The International Conference on Evolutionary Computation Theory and Applications (ECTA), the International Conference on Fuzzy Computation Theory and Applications (FCTA), and the International Conference on Neural Computation Theory and Applications (NCTA). Recent progresses in scientific developments and applications in these three areas are reported in this book. IJCCI received 111 submissions, from 30 countries, in all continents. After a double blind paper review performed by the Program Committee, only 24 submissions were accepted as full papers and thus selected for oral presentation, leading to a full paper acceptance ratio of 22%. Additional papers were accepted as short papers and posters. A further selection was made after the Conference, based also on the assessment of presentation quality and audience interest, so that this book includes the extended and revised versions of the very best papers of IJCCI 2013. Commitment to high quality standards is a major concern of IJCCI that will be maintained in the next editions, considering not only the stringent paper acceptance ratios but also the quality of the program committee, keynote lectures, participation level and logistics.

Abstract: Abstract of thesis entitled Scheduling Trucks in Port Container Terminals by a Genetic Algorithm Submitted by Zhang Yuxuan For the Degree of Master of Philosophy at the University of Hong Kong in August 2005 The recent trend of trade globalization has significantly increased the importance of the global marine transportation industry. As operation efficiency is of paramount importance to today's marine transportation industry, port container terminals have been working hard to improve their operation performance. In most port container terminals, trucks are frequently used as the transportation equipment to ferry containers between huge container handling equipment within a terminal. Thus, trucks are important equipment linking isolated operations in various terminal locations together to facilitate a smooth flow of containers from the yard to the quay and vice versa. Efficient truck operation can speed up container handling processes, smooth container flows and thus improve a terminal's performance. This research studies the Truck Scheduling Problem - the problem of scheduling a fleet of trucks to perform a set of transportation jobs with sequence-dependent processing times and different ready times to minimize the makespan of all the jobs. The scheduling problem is formulated as a mixed-integer program. It is noted that the scheduling problem is NP-hard and the computational effort for solving even small-scale test problems is prohibitively large. This research proposes to use a Genetic algorithm (GA) to solve the scheduling problem as GAs are often superior to other heuristic algorithms, due to GAs' unique features of global search and convergence. Major components of the GA proposed in this research, such as representation, initialization, fitness evaluation, selection, crossover and mutation, are discussed in detail. Improvements are made to some of the components of a standard GA to enhance its search ability. A heuristic initialization scheme is proposed to generate an initial population with better fitness. As the crossover operator plays an important role in a GA's performance and is regarded as the primary engine of exploitation in GAs, this research develops an effective crossover scheme, called Greedy Crossover, based on the characteristics of the scheduling problem. A comprehensive set of test problems randomly generated based on real-life terminal operations data is used to compare the performance of the proposed GA using Greedy Crossover with that of the GAs using six effective crossover schemes reported in the literature. The computational results demonstrate that Greedy Crossover outperforms the six crossover schemes, with Greedy Crossover's solutions on average 4.05% better than the best solutions found by the six crossover schemes.

Download or read book Handbook of Ocean Container Transport Logistics written by Chung-Yee Lee and published by Springer. This book was released on 2014-12-13 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is focused on the impact of ocean transport logistics on global supply chains. It is the first book solely dedicated to the topic, linking the interaction of parties along this chain, including shippers, terminal operators and line carriers. While ocean container transport logistics has been greatly studied, there are many important issues that have yet to receive the attention they deserve. The editors and contributing authors of Ocean Container Transport Logistics: Making Global Supply Chain Effective seek to address these topics and shed new light on the subject. The book is divided into three parts. Part I examines the innovation, trends, competition and business model of container terminal operations. In Part II, the book looks at how tactical and operational management is used in shipping liners. The chapters cover topics such as empty container repositioning, slow steaming, routing, network design and disruption management. Finally Part III explores at shippers and global supply chain management, with chapters on transportation service procurement, hinterland transportation, green corridors, as well as competition and co-operation in maritime logistics operations. The eighteen chapters of the book all highlight the immediate effect of ocean transport logistics on global supply chain.

Download or read book Handbook of Terminal Planning written by Jürgen W. Böse and published by Springer Science & Business Media. This book was released on 2011-02-26 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: Container Terminals (CT) operate as central nodes in worldwide hub-and-spoke networks and link ocean-going vessels with smaller feeder vessels as well as with inbound and outbound hinterland transportation systems using road, rail, or inland waterways. The volume of transcontinental container flows has gained appreciably over the last five decades -- throughput figures of CT reached new records, frequently with double-digit annual growth rates. Stimulated by throughput requirements and stronger competition between terminals settled in the same region or serving a similar hinterland, respectively, cost efficiency and throughput capabilities become more and more important. Nowadays, both terminal capacity and costs have to be regarded as key indicators for CT competitiveness. In respect of this steady growth, this handbook focuses on planning activities being aimed at “order of magnitude improvements” in terminal performance and economic viability. On the one hand the book is intended to provide readership with technological and organizational CT basics for strategic planning. On the other hand this book offers methodical assistance for fundamental dimensioning of CT in terms of 'technique', 'organization' or 'man'. The former primarily considers comprehensive information about container handling technologies representing the state of the art for present terminal operations, while the latter refers to methodological support comprising in particular quantitative solutions and modeling techniques for strategic terminal decisions as well as straightforward design guidelines. The handbook includes an introductory contribution which gives an overview of strategic planning problems at CT and introduces the contributions of the volume with regard to their relationship in this field. Moreover, each paper contains a section or paragraph that describes the impact of findings investigated by the author(s) for problem-solving in long-term planning of CT (as an application domain). The handbook intends to provide solutions and insights that are valuable for both practitioners in industry who need effective planning approaches to overcome problems and weaknesses in terminal design/development and researchers who would like to inform themselves about the state of the art in methodology of strategic terminal planning or be inspired by new ideas. That is to say, the handbook is addressed to terminal planners in practice as well as to students of maritime courses of study and (application oriented) researchers in the maritime field.

Download or read book Multi Criteria Decision Making in Maritime Studies and Logistics written by Paul Tae-Woo Lee and published by Springer. This book was released on 2017-10-24 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes a wide range real-case applications of Multi-Criteria Decision Making (MCDM) in maritime related subjects including shipping, port, maritime logistics, cruise ports, waterfront developments, and shipping finance, etc. In such areas, researchers, students and industrialists, in general, felt struggling to find a step-by-step guide on how to apply MCDM to formulate effective solutions to solving real problems in practice. This book focuses on the in-depth analysis and applications of the most well-known MDCM methodologies in the aforementioned areas. It brings together an eclectic collection of twelve chapters which seek to respond to these challenges. The book begins with an introduction and is followed by an overview of major MCDM techniques. The next chapter examines the theory of analytic hierarchy process (AHP) in detail and investigates a fuzzy AHP (FAHP) approach and its capability and rationale in dealing with decision problems of ambiguous information. Chapter 4 proposes a generic methodology to identify the key factors influencing green shipping and to establish an evaluation system for the assessment of shipping greenness. In Chapter 5, the authors describe a new function of fuzzy Evidential Reasoning (ER) to improve the vessel selection process in which multiple criteria with insufficient and ambiguous information are evaluated and synthesized. Chapter 6 presents a novel methodology by using an Artificial Potential Field (APF) model and the ER approach to estimate the collision probabilities of monitoring targets for coastal radar surveillance. Chapter 7 develops the inland port performance assessment model (IPPAM) using a hybrid of AHP, ER and a utility function. The next chapter showcases a challenging approach to address the risk and uncertainty in LNG transfer operations, by utilizing a Stochastic Utility Additives (UTA) method with the help of the philosophy of aggregation–disaggregation coupled with a robustness control procedure. Chapter 9 uses Entropy and Grey Relation Analysis (GRA) to analyze the relative weights of financial ratios through the case studies of the four major shipping companies in Korea and Taiwan: Evergreen, Yang Ming, Hanjin and Hyundai Merchant Marine. Chapter 10 systemically applies modern heuristics to solving MCDM problems in the fields of operation optimisation in container terminals. Arguing that bunkering port selection is typically a multi-criteria group decision problem, and in many practical situations, decision makers cannot form proper judgments using incomplete and uncertain information in an environment with exact and crisp values, in Chapter 11, the authors propose a hybrid Fuzzy-Delphi-TOPSIS based methodology with a sensitivity analysis. Finally, Chapter 12deals with a new conceptual port performance indicators (PPIs) interdependency model using a hybrid approach of a fuzzy logic based evidential reasoning (FER) and a decision making trial and evaluation laboratory (DEMATEL).
