A dispatching and shifting method suitable for one-way continuous lock-passing ships

Abstract

A dispatching and shifting method suitable for one-way continuous lock-passing ships, including constructing an optimal dispatching and shifting plan for ships waiting to be locked, performing pre-shifting, and notifying the waiting ships to arrive at a designated position on a berthing pier at a designated time and berthing number; Based on the gearing model and ship information, the secondary gearing model of ships passing through the lock is established. Based on the secondary gearing model, with the goal of minimizing the time cost of the gate, the iterative algorithm is used to calculate the time cost of the lock-passing plan, and the time cost of the gate-passing minimum is selected. The scheme is the sequence of ships entering the gate and the position after entering the gate; then according to the time of gate opening and closing and the speed of the ship, according to the secondary shifting model, the scheme with the smallest time for the next gate passage is obtained, and the next gate is accurately indicated. The lock time is the exact position where each ship arrives at the waiting area at a specific time. The invention can reduce the gate passage units as far as possible, improve the utilization rate of the gate chamber, shorten the gate passage time, and thus improve the navigation efficiency.

Description

Technical field [0001] The invention relates to the technical field of water transportation, in particular to a dispatching and shifting method suitable for a one-way continuous gate ship. Background technique [0002] The ship lock is used as a channel for ships to pass through the water conservancy hub by opening and closing the discharge valve. According to the structure, it can be divided into a single-level ship lock and a multi-level ship lock. Multi-level ship locks. The single-line ship lock adopts a two-way continuous pass method, that is, when the ship in the lock chamber is completed, the ship entering the lock in the opposite direction will start to enter the lock, and the ship passing the lock is always up and down, cyclically, and its passing efficiency is mainly Depends on the ship's gate time for single gate times. The multi-level ship lock adopts the one-way continuous gate method, that is, after the ship in the first lock chamber enters the lock, the ship lock...

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
