Restow control method for improving access efficiency of terminal containers

Abstract

The invention provides a restow control method for improving the access efficiency of terminal containers. The method comprises the steps that the container information, the stack information and the extraction order requirement of a shell area in the charge of a crane are determined; the containers are divided; the number of required target stacks and the target height of each target stack are determined; the target stacks are successively selected from the current storage containers and non-blocking stacks to acquire an initial control scheme; according to the initial control program, simulation operation is carried out on each target stack to acquire crane command information, and crane command evaluation parameters are determined; according to the crane command information, a switching neighborhood search method is used to carry out iterative optimization on the control scheme to acquire a final control scheme; and the final control scheme is converted into a crane operation command to control the crane to reach a designated position, and successive operations are carried out on the target stacks. According to the method, crane operations are centralized to reduce the extraction time, the berthing time of a ship and the transport logistics cost of the containers, and the turnover efficiency of a container terminal is improved.

Description

technical field [0001] The invention belongs to the field of information technology, and in particular relates to a control method for pre-empting containers that improves the access efficiency of dock containers. Background technique [0002] The container yard is an important buffer link in the container transportation process, especially in the container terminal, such as figure 1 As shown, as a transfer station connecting land transportation and sea transportation, the wharf has extremely high requirements on the operation efficiency of its internal storage yard. [0003] In a container yard, a row of containers stacked vertically is called a stack, and multiple stacks stacked side by side form a stack. If the container to be picked up is not at the top of the stack, all the containers stacked on it must first be turned over to other stacks. This process is called container dumping. In yard operations, factors that affect the rate of container dumping include: the stac...

Problems solved by technology

There are many literatures that have studied the container reversing problem. For example, Chen Qiushuang and Yang Lizhi studied how to solve the container reversing problem through heuristic algorithms in "Research on Heuristic Algorithms for Container Reversing Problems", but these studies only considered how to reduce the number of reversing containers , without considering the centralized stacking of containers
