Embodiment Construction

[0026] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0027] The warning area is the core of the system planning of the ship routing system. The optimization of the ship routing system scheme focuses on the reasonable arrangement of the warning area, and on this basis, the comparison and optimization of the ship routing system schemes are carried out. For this reason, the present invention provides a kind of warning area setting method based on 0-1 integer programming of ship routing system system, and this method comprises the following steps (such as figure 1 shown):

[0028] (1) Set up several nodes on the deep-water route in the core port area, and obtain the AIS data distribution of the ship flow after periodic statistics from the VTS control center;

[0029] (2) Obtain each node and its dail...

Abstract

The invention discloses a method for optimizing a ship routing system warning region based on 0-1 integer programming, comprising the following steps: (1) setting a plurality of sectional points to obtain AIS (Automatic Identification System) data distribution of ship flow; (2) obtaining each sectional point and average daily flow from the sectional point to each wharf; (3) setting the positions of warning regions; (4) initializing the number of the warning regions and the preset space lengths of the warning regions; (5) routing the relationship between the ship tonnage and the ship total length in various ship sizes in the statistic flow; (6) building a ship routing scheme; (7) calculating equivalent lost mileage and average mileage generated by circumambulation; (8) calculating average cargo dead weights of a ship on a main channel and a branch channel; and (9) calculating the good transportation lost mileage or equivalent lost mileage of the passing ships. Ships can move within the solution space of the preset warning region with an optimized decision method provided by the invention so that excellent search capability on the optimal solution is obtained.

Description

technical field [0001] The invention relates to a planning technology of a ship routing system, in particular to a method for setting a warning area of ​​a ship routing system based on 0-1 integer planning. Background technique [0002] Liu Dexin systematically summarized and summarized 11 technical factors that should be considered in traffic separation planning and design, proposed corresponding analysis methods, proposed corresponding traffic separation schemes, and used the fuzzy AHP method to analyze the traffic separation between different traffic separation schemes in the same water area. Comprehensive evaluation of relative pros and cons. [0003] Fang Xianglin proposed the general principles and steps of the computer-aided modeling and optimization design method of traffic separation system, and took Laotieshan Waterway as an example to provide a design example. [0004] Weng Yuezong developed software for processing and analyzing traffic data based on electronic c...
