Dynamic Analysis Of Container Terminal Logistics System And Simulation

As a important part of international transportation chain and logistics chain, container transport trade plays a crucial role, and further more, some advanced country look it as a important symbol behaved their integrated logistics competition. Container Terminal, which is a container transport nerve, connects the water transport with land-carriage, it affects the container transport. Because of application of modern hi-tech in port, the loaded and unloaded system becomes more and more large-scale, high-speed, automatism, and information, and the size of Container Terminal is more big, the work efficiency is more high and the throughput is also more much. Just because of all this, the conventional design of port distinct with the operation fact of modern Container Terminal. Design method of port needs improvement constantly, and design thought also needs innovation.Container terminal logistics is an organic system, made of interactive and dynamic components, such as containers, ships, berths, yards, tracks, quay cranes and yard cranes, trucks, labors and communications, in a limited terminal space. It is a complex discrete event dynamic system related to kinds of complicated problems in logistics transport field.The paper look back research trends of Container Terminal, sum up the fault, and according the characteristics of port container logistics system, and describe and analyse the stochastic process particularly, and achieved their statistics rule.Then according to the flexible berthing of along-shore port, the paper treat the state of berth as a stochastic process, and put up the model based on Markov chain theory, and work out the one-step-matrix and state transfer chart. The model offer a reference of transfer of berth state.Then the paper set up the system simulation model based on WITNESS software. We can achieve the standard sample path according the model, and then set up the integrated model based the Perturbation Analysis theory and work out the mostly parameter sensibility. And analyse the effect on system of thesensibility.Finally the paper runs the system simulation model many times according to different simulation purposes, simulation contents and experiment conditions. And compared with some kinds of design , choose the best. The run results offer a reference for design of port and practice operation.
