AI Technical Summary

Problems solved by technology

[0005] In general, the existing dispatching mostly considers a single ship lock, and optimizes the dispatching of the lock block, so as to improve the utilization rate of the lock chamber, but there is little research on the joint dispatching of multi-node channels.

Embodiment Construction

[0063] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments. The present invention selects the Yangzhou section of the Yanshao line as a specific embodiment for introduction.

[0064] Definition of terms:

[0065] (1) One-way navigation: At any time, only one ship (a fleet) can enter the channel section at most.

[0066] (2), ship overtaking: the following ship chases and overtakes the front ship by virtue of its speed advantage, which is similar to overtaking on the road.

[0067] (3) Vessel intersection: refers to the frontal intersection of ships traveling in the same direction.

[0068] (4) Number of virtual overtakes: the number of ships sailing from one section of the channel to the other end of the channel at their normal speed and able to overtake the ships in front. Since overtaking occurs mainly when a single ship overtakes a fleet, each time a single ship can overtake a fleet, the "virt...

Abstract

The invention discloses a simulation method for scheduling a multi-code channel. The simulation method comprises the following steps: (1) analyzing the current situation of the channel and building a scheduling model; (2) designing a target performance function and solving a scheduling scheme for scheduling the channel based on a simulated annealing algorithm; (3) introducing a heuristic scheduling rule and improving the simulated annealing algorithm; and (4) combining a risk exceeding index, simulating, comparing and analyzing the schemes before and after improving the algorithm to judge the scheduling scheme. The method not only can supply powerful technology support and scientific basis for scheduling the operation of ships under complex navigation conditions, but also can ensure the ship navigation safety of the ships under the complex navigation conditions and increase the utilization rate of the channel resource, and has very important practical significance for guaranteeing a good ship navigation environment and ship navigation order of the channel.

Description

technical field [0001] The invention relates to a simulation method for multi-node waterway scheduling, which belongs to the field of shipping traffic. Background technique [0002] In recent years, with the rapid development of the economy, the traffic volume of inland waterways has increased significantly. For multi-node waterways, due to the restrictions of ship locks and navigable sections, ship blockages have occurred from time to time, resulting in the interruption of the waterway and causing large economic loss. In order to improve the smoothness of the channel, it is necessary to dispatch the passing ships. Since multiple locks and node sections are involved, it is essentially a joint dispatch of multi-node channels. [0003] On the basis of statistical analysis of 54 ship locks managed by the waterway department of Jiangsu Province, Zhang Yutao et al. designed the principles of ship queuing and ship lock order according to the ship lock operation scheduling process...
