Microscopic simulation method of handling traffic system layout and traffic organization of container terminal

Abstract

The invention belongs to the technical field of planning design and management of transportation terminals, and provides a brand new method for enterprise handling traffic system layout and traffic organization management of a container terminal. Efficiency of handling traffic system layout and traffic organization of the whole container terminal is improved. According to the technical scheme, a microscopic simulation method of handling traffic system layout and traffic organization of the container terminal comprises the steps of building a microscopic simulation frame of handling traffic system layout and traffic organization of the container terminal; selecting a cell; running a cellular automaton, wherein initialization of the cell is carried out, and operation of the cellular automaton is carried out. When the operation of the cellular automaton is carried out, a front container yard module rule, a collected truck queue module rule, update of an apron road and a collected truck queue module rule are adopted. The microscopic simulation method of handling traffic system layout and traffic organization of the container terminal is mainly applied to planning design of the transportation terminals.

Description

technical field [0001] The invention belongs to the technical field of transportation station planning, design and management, and in particular relates to a microcosmic simulation method for the layout and traffic organization of a container terminal loading and unloading transportation system. technical background [0002] Aiming at the problem of improving the layout and traffic organization efficiency of container terminal loading and unloading traffic system, domestic and foreign scholars have made some researches, which can be roughly divided into three categories: one is to use mathematical analytical models, for example: Ballis and Abacoumkin established a system due to equipment mismatch And the resulting traffic jam and delay model, they use this model to evaluate a terminal's yard design, the number of equipment, truck arrival, operating rules. Yang Lei used the method of enumeration to propose a planning model for the layout of trestle bridges. Through experiment...

Problems solved by technology

[0004] (1) Most of the current research on this issue remains at the stage of theoretical exploration, and some studies use mathematical models to simulate the dock yard. However, due to the limitations of the mathematical model, it is impossible to describe the actual operation of the yard and the front of the dock in detail, and The results do not correspond to the actual situation

[0005] (2) There are also some studies that use simulation software, such as EM-Plant and Flexsim, to simulate container terminals. However, due to the specificity of the simulation objects of the existing simulation software, it is impossible to integrate and describe the overall system of the terminal and the yard; on the other hand , the simulation software cannot refine all the key components of the overall system of the research object, and cannot achieve microscopic simulation, and there is still a certain distance from the actual situation

[0006] (3) Some studies use cellular automata to perform micro-simulation on the yard and the front of the wharf, but they also use traditional two-dimensional cells, which are far from the three-dimensional space where the goods are placed in the actual wharf yard. The real situation does not match
