Embodiment Construction

[0105] The specific embodiment of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0106] It should be noted that, in the following specific embodiments, when describing the embodiments of the present invention in detail, in order to clearly show the structure of the present invention for the convenience of description, the structures in the drawings are not drawn according to the general scale, and are drawn Partial magnification, deformation and simplification are included, therefore, it should be avoided to be interpreted as a limitation of the present invention.

[0107] In this specific embodiment, it is assumed that one stack area is provided with two field bridges. In order to give full play to the operating efficiency of the two yard bridges, reduce the waiting time of the trucks, and ensure the safe working distance of the two yard bridges, it should be ensured that the positions of the two matched contai...

Abstract

The invention discloses a container ship loading method based on a double-forty-foot quayside crane, Container pairing model is established to match yard containers. Based on the constraint of ship stability index and the position of pairing containers on the ship, in order to minimize the sum of ship dumping quantity and yard dumping quantity, a container ship stowage 0-1 integer programming model based on double 40-foot quay cranes is constructed, and a heuristic algorithm is designed to solve the two models respectively. The invention has the remarkable characteristics of simultaneously considering the operation characteristics of the double 40-foot quayside crane, the loading and unloading efficiency of the ship, the ship loading demand and the like, and is suitable for providing a loading scheme for large ships and solving the problem at a high speed.

Description

technical field [0001] The invention relates to the technical field of container terminals, and more specifically, to a container ship stowage method based on double forty-foot quay bridges. Background technique [0002] The rapid development of containerization makes the container throughput of the container terminal continuously increase, which brings great opportunities and challenges to the container terminal. As a transit point for sea and land transportation, container terminals play a very important role in global commerce and trade. Improving the operating efficiency of container terminals is an important prerequisite for improving the turnover rate of container ships at the terminal, and the turnover rate of container ships at the terminal is important for the shipping company. economically important. Therefore, in recent years, some advanced terminal operation equipment that can improve the operation efficiency of container terminals and reduce the turnaround time...
