Scheduling and gear-arranging method suitable for one-way continuous gate-passing ship

Abstract

A scheduling and gear-arranging method suitable for a one-way continuous gate-passing ship comprises: establishing an optimal scheduling gear scheme of the ship to be braked, performing gear pre-arrangement, and notifying the ship to be braked to arrive at the designated position of a berthing pier according to designated time and berthing number; based on the pre-gear-arranging model and the shipinformation, establishing a secondary gear-arranging model of the gate-passing ship, calculating the time cost of the gate-passing scheme by applying an iterative algorithm according to the secondarygear-arranging model and with the minimum gate-passing time cost as the target, and selecting the scheme with the minimum gate-passing time cost as the ship gate-entering sequence and the gate-entering position; and according to the gate opening and closing time and the ship traveling speed, obtaining a scheme with the minimum gate passing time of the next gate through calculation according to asecondary gear-arranging model, and accurately indicating each ship of the next gate to reach the exact position of the to-be-braked area at the specific moment. Gate passing units can be reduced as much as possible, the utilization rate of the lock chamber is increased, the gate passing time is shortened, and the navigation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of water transportation, in particular to a dispatching and shifting method suitable for one-way continuous lock-passing ships. Background technique [0002] Ship locks are used to realize the passage of ships in water conservancy projects through the opening and closing of discharge valves. According to the structural form, ship locks can be divided into single-stage ship locks and multi-stage ship locks. That is, those with only one lock chamber are single-stage ship locks, and those with two or more continuous lock chambers are called single-stage ship locks. Multi-stage locks. The single-line ship lock adopts a two-way continuous lock-passing method, that is, after the ships in this lock chamber have exited the lock, the ships entering the lock in the direction opposite to the exiting direction begin to enter the lock. Depends on the time of ships passing through a single gate. The one-way continuous l...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the serious backlog of ships, long waiting time for the lock, and low utilization rate of the lock chamber in the process of dispatching and shifting in the prior art; and the shifting process is only based on the declaration time, without comprehensive consideration of the coordination, balance and Issues such as the principle of coordinated dispatch and safety for both large and small ships
