基于模拟减少集装箱船待港时间的实用方法(英文)

The main challenge for container ports is the planning required for berthing container ships while docked in port.Growth of containerization is creating problems for ports and container terminals as they reach their capacity limits of various resources which increasingly leads to traffic and port congestion.Good planning and management of container terminal operations reduces waiting time for liner ships.Reducing the waiting time improves the terminal’s productivity and decreases the port difficulties.Two important keys to reducing waiting time with berth allocation are determining suitable access channel depths and increasing the number of berths which in this paper are studied and analyzed as practical solutions.Simulation based analysis is the only way to understand how various resources interact with each other and how they are affected in the berthing time of ships.We used the Enterprise Dynamics software to produce simulation models due to the complexity and nature of the problems.We further present case study for berth allocation simulation of the biggest container terminal in Iran and the optimum access channel depth and the number of berths are obtained from simulation results.The results show a significant reduction in the waiting time for container ships and can be useful for major functions in operations and development of container ship terminals.     

PORT OF SEATTLE STATEMENT REGARDING 21ST CENTURY

It is impossible to overstate the importance of the World Wide Web to any business, including ports, and there will come a day in the not-too-distant future when all internal and external processes involving the Port of Seattle will be Web-based. We see nothing but growth in the continued application of the Web to our everyday business. The Port has launched a five-year eBusiness strategy to help maintain our position as an innovative leader among ports. There are virtually no     

Design and implementation of a visual monitoring system to ensure safety in the water surrounding a container vessel

Container vessels navigate among the world's ports,frequently passing through narrow and congested waters.Due to the many layers of containers on a container vessel's decks,it is difficult for the crew to be aware of all fishing vessels and other obstacles in a container vessel's radar observation blind zone.This greatly increases the risk of collisions and other accidents.Given such great challenges to safe navigation and safety management with container vessels,their security risks are severe.An effective visual monitoring system can improve the safety of the water area surrounding container vessel by eliminating a vessel's observation blind zone,providing an effective safety measure for vessels navigating fishing zones and other troublesome areas.The system has other functions,such as accident recording,ship security,and monitoring of loading and unloading operations,thus ensuring the ship operates safely.Six months'trial operation showed that the system facilitates safe navigation of container vessels.     

加强内地与香港交通合作 发挥香港国际航运中心作用

<正>Dear readers,welcome to read this issue of our jour-nal,Ports of China.The Chinese Government is going to resume exercis-ing sovereignty over Hong Kong.This is a grand eventthat has been drawing world attention.The port in HongKong is one of the busiest ports of the world,ranking asthe world’s biggest container port for five consecutiveyears.Therefore,Hong Kong’s return to the motherlandis a significant event for the Chinese ports industry aswell.In order to celebrate this epoch-making event,weare opentng a special column in this issue,Hong KongComing Back.For this column,Mr.Huang Zhendong,Minister of Communications,sent us his essay,entitled"Strengthening Cooperation Between Hong Kong and theInland Areas in Communications,Mobilising HongKong’s Functions as an International Shipping Center".Mr.Li Weizhong,President,China Ports and HarborsAssn,Also contributed his essay "Hailing Hong Kong’sReturn That Has Wiped Out the Old Humiliation,Look-ing out for a Better Megaport in the Future".also run inthis c     

Model and algorithm for container ship stowage planning based on bin-packing problem

In a general case, container ship serves many different ports on each voyage. A stowage planning for container ship made at one port must take account of the influence on subsequent ports. So the complexity of stowage planning problem increases due to its multi-ports nature. This problem is NP-hard problem. In order to reduce the computational complexity, the problem is decomposed into two sub-problems in this paper. First, container ship stowage problem （CSSP） is regarded as “packing problem”, ship-bays on the board of vessel are regarded as bins, the number of slots at each bay are taken as capacities of bins, and containers with different characteristics （homogeneous containers group） are treated as items packed. At this stage, there are two objective functions, one is to minimize the number of bays packed by containers and the other is to minimize the number of overstows. Secondly, containers assigned to each bays at first stage are allocate to special slot, the objective functions are to minimize the metacentric height, heel and overstows. The taboo search heuristics algorithm are used to solve the subproblem. The main focus of this paper is on the first subproblem. A case certifies the feasibility of the model and algorithm.     

Regulations for Inspection of Vessels Engaged in International Voyages Entering and/or Leaving the Ports of the People's Republic of China

Article 1 The present regulations are formulated for the purposes of strengthening the control over vessels engaged in international voyages entering and/or leaving the ports of the People's Republic of China, facilitating vessels entering and/or leaving the ports and of enhancing port efficiency.

BOX traffic boom in Changjiang region The container transport along the Changjiang River is developing rapidly. According to Shanghai port statistics,container lines initiated from the Changjiang ports to Shanghai has amounted to 11 with 21,000 TEU monthly volume, one times that of the last same period. The rapid development has attracted quite a lot of cornpanies to engage in cornpetition. Up to now,80％of total 150 domestic international lines set up cargo agencies at the Changjiang ports. Moreover, the container boom gives an impetus to the construction, rebudding and expansion for the transport facilities of the Changjiang ports. Additionally, the transhiprnent statiorls in the hinterland of the ports and along the major highways are being established along with the boom.     

A well-functioning port is a stimulus for economy

Until just a few years ago, ports in Europe had a rather wishy-washy image. In the eyes of both the public and politicians, ports were a necessary fact of life.

中国港口基础设施建设中的问题及其当务之急

The 1990s have witnessed a dramatic surge ahead in China' s port infrastructure construction with several Chinese ports registering as some of the fastest growing in the world at the present time, However, the pace of development is so rapid and centred on so many different ports that there are fears that the pendulum may be swinging in the other direction, Questions are now being raised about whether container handling capacity now exceeds demand by too wide a margin.
