Ship arrival queuing scheduling method

Abstract

The invention discloses a ship arrival queuing scheduling method, which comprises the steps of setting port waiting areas, wherein each waiting area belongs to at least one berth; making a ship scheduling general plan of the whole port, and splitting the general plan into a plurality of sub-plans representing ship arrival scheduling of all berths associated with the to-be-berthed area in a time period for each to-be-berthed area; executing the sub-plans, scheduling the ships in the sub-plans to berth operation, and updating the data of the ships to be scheduled in the sub-plans; polling the to-be-dispatched ships in the plan when the to-be-berthed area is idle, determining that the first ship which is located on the anchor ground and conforms to the attribute data of the to-be-berthed areain the queue enters the to-be-berthed area, forming a to-be-berthed area navigation instruction, and sending the to-be-berthed area navigation instruction to the determined ship for execution; and receiving a signal that the ship arrives at the to-be-berthed area, and updating the position information of the ship from the anchored ground to the to-be-berthed area. The method can reduce the voyageand navigation time of the ship from the starting place to the berth, thereby reducing the berth empty berthing time and the non-production time of the ship at the port.

Description

technical field [0001] The invention relates to the field of ship dispatching, in particular to a ship arrival queuing dispatch method. Background technique [0002] Ships need to pass through the channel twice to enter and leave the port. The ship enters the berth through the channel from the anchorage, and then leaves the port through the channel again. Determine whether the ship can enter the channel. The purpose of channel scheduling is to maximize the use of channels and minimize the waiting time of ships, seek to maximize the passing capacity per unit time, and arrange and dispatch ships economically and rationally. [0003] Ports generally set up anchorages in the peripheral area of ​​the port. Anchorages refer to the waters in the port for ships to berth safely, take shelter from the wind, customs border inspection, quarantine, cargo loading and unloading, and barge marshalling operations. Its area is determined by factors such as the anchoring method, the number a...

AI Technical Summary

Problems solved by technology

However, most of the current dispatching methods for ships entering the port are aimed at queuing directly from the anchorage to the berth. There is no scientific dispatching plan for the ship to arrive at the berthing area from the berth first and then from the berthing area to the berth.
