Available in PDF, EPUB and Kindle. Book excerpt: This report compares the performance of three double-cycling algorithms used to determine the sequence with which to load and unload containers from a vessel with a quay crane. Double cycling is a technique which can improve the efficiency of a quay crane and container port by unloading and loading containers in the same crane cycle. The three algorithms, the greedy strategy, the proximal strategy, and Johnson's rule, are introduced and results from applying the three strategies to a set of simulated vessels are compared. While Johnson's rule provides the minimum number of cycles required to unload and load a vessel using double cycling, it is operationally less convenient. The proximal strategy is operationally convenient, but provides a smaller benefit when compared to single cycling. All strategies provide significant benefit (about a 40% reduction over single cycling for hatchless ships), and the results are not particularly sensitive to the algorithm used.

Book Synopsis Reducing Ship Turn-around Time Using Double-cycling by : Anne Victoria Goodchild
Download or read book Reducing Ship Turn-around Time Using Double-cycling written by Anne Victoria Goodchild and published by . This book was released on 2004 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Double cycling improves efficiency by unloading and loading a ship simultaneously; using wasted crane moves to transport containers. This paper demonstrates that double cycling can reduce ship turn-around time through this efficiency improvement. The paper describes the nature of the double cycling problem and, for a given loading-plan, quantifies the benefits using a greedy algorithm. The relationship between the benefits of double cycling, and the problem parameters is analyzed using simple formulas and a simulation program. This paper demonstrates that double cycling can create significant efficiency gains, and should benefit any party interested in improving port operations, and reducing the cost of container shipping.

Book Synopsis Research on Marine Terminal Logistics by : Dusan Ku
Download or read book Research on Marine Terminal Logistics written by Dusan Ku and published by . This book was released on 2015 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine terminals are the gateways in global distribution networks and play a vital role in completing the global supply chains. With the rapidly growing level of service requirement that shipping lines make of terminal operators, the efficiency of terminal operation is becoming a matter of business survival. Thus, a substantial amount of investment has been made in port developments, in both facilities and IT infrastructure especially over the last two decades. Pursuant to this inevitable trend in industry, we also observe that a rich body of research has emerged in the academia for the study of optimisation in marine terminal operations. This thesis focuses selectively, among other optimisation problems in marine container terminals, on the seaside planning and optimisation problems. As a viable and economic option to improve vessel productivity, which is regarded as the most critical key performance indicator in marine terminal operations, the crane double cycling strategy has received substantial interests from both academia and industry. However, the practical operation strategy for implementing such concept has been limited to a bare minimum partially due to a lack of practical research or practitioners' fear for a change against the status quo. This is where the motivation for this research has arisen. This research is comprised of three original papers. Paper I provides a comprehensive review of the literature on the quay crane (QC) schedule problem and fills the gap in the literature by providing an exact model for preemptive schedules of bay-wise vessel operation. Paper II provides a comprehensive review on the research of crane double cycling problem and identifies that the next challenge in this research is in the formulation of the multi-quay crane double cycling problem. Thus, it presents the motivations and discussions on future research directions with a focus on practical constraints. Finally, Paper III presents the multi-QC double cycling model that this research is aimed at developing. As a computational study, the models presented in this research are based on computational and optimisation theory. Methodology section in the introductory chapter addresses the relevant theory and implementation perspective applied to each model: In Paper I, the QC scheduling problem is formulated into a mixed integer programming. Due to its - completeness, a relaxed formulation with Lagrangian relaxation is also presented. In Paper III, the multi-QC double cycling problem is formulated into an integer programming. Also due to its -completeness, a meta-heuristic approach is presented to cope with the computational intractability. Computational results are shown for analysis with discussions on the future research paths.

Book Synopsis Handbook of Terminal Planning by : Jürgen W. Böse
Download or read book Handbook of Terminal Planning written by Jürgen W. Böse and published by Springer Nature. This book was released on 2020-09-14 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seaport Container Terminals (SCT) 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 enormously over the last five decades frequently leading to double-digit annual growth rates for the SCT. The 2nd edition of the Handbook of Terminal Planning also deals with problems being induced by questions of terminal development on a long-term basis (strategic level). Facing present and upcoming challenges for SCT operation—such as more and more mega vessels, extremely high hinterland peaks, higher environmental standards, less public acceptance and the stronger competition between terminals serving the same hinterland—the focus of the book is on successful approaches and solutions primarily addressing the planning of terminal structures. Nevertheless, operational aspects are considered, as well as how they effectively contribute to problem solving on the strategic level.

Book excerpt: With increased globalization and offshore sourcing, global supply chain management is becoming an important issue for many businesses as it involves a company's worldwide interests and suppliers rather than simply a local or national orientation. The storage systems significantly affect the level of quality of products, the customer’s service level, and the global logistic cost. The mission of warehousing systems design, control and optimization is to effectively ship products in the right place, at the right time, and in the right quantity (i.e. in any configuration) without any damages or alterations, and minimizing costs. Warehousing in the Global Supply Chain presents and discusses a set of models, tools and real applications, including a few case studies rarely presented with a sufficient detail by other literature, to illustrate the main challenges in warehousing activities. This includes all warehouse operations (from receiving to shipping), problems and issues (e.g. storage allocation, assignment, layout, vehicle routing) for industrial and service systems as parts of global supply chains. Advanced and effective solving methods are also illustrated and the discussed case studies help the reader to quickly apply the proposed models and techniques/algorithms. Warehousing in the Global Supply Chain is useful to managers and practitioners of industry and service sectors for the determination and modeling of the critical issues concerning warehousing systems planning and design. It is a valuable source of information for engineering students, doctoral and post-doctoral students, and researchers of academic institutions who are searching for advanced modeling approaches and solving techniques to complex logistic decision making problems.
