Pre-turning box finishing method of dock export carton of large-scale container before shipping

Abstract

The invention discloses a pre-turning carton finishing method of a dock export carton of a large-scale container before shipping, which comprises the following steps of: determining a target state of a pre-turning carbon, and marking a fixed carton in an initial stockpiling state according to the target state of the pre-turning carton; carrying out a carton-turning operation to a non-fixed carton in the initial stockpiling state and recording the times of carton-turning according to the control rule of the ineffective turning carton until the carton is unnecessary to turn in the stockpiling position so as to form a plurality of pre-turning carton finishing schemes; and determining the scheme with the least times of effective carton-turning to be a pre-turning carton finishing optimal scheme. The method can realize the intelligence, the optimization and the rapid strategy of the pre-turning carton scheme of the dock export carton of the large-scale container, reduce carton-turning times and improve carton-turning efficiency. With advanced determination of the target state of the pre-turning carton, the marking of the fixed carton in the initial stockpiling state and in the searching process of the carton-turning scheme and control rules of ineffective carton-turning, the pre-turning carton finishing method effectively controls the search space of the scheme and the complexity of calculation and optimizes the carton-turning times. In the method, effectiveness determination and optimal adjustment are also carried out on carton-turning twice or more to optimize the carton-turning times and ensure that the carton-turning efficiency is higher.

Description

technical field [0001] The invention relates to container overturning technology in large container wharfs, in particular to a method for pre-turning over and arranging containers exported from large container wharfs before loading. Background technique [0002] In order to improve competitiveness, container terminals are constantly pursuing the highest efficiency with the lowest cost expenditure, and container overturning in the yard has always been an important factor affecting cost and efficiency. [0003] For export containers, due to the unpredictability of the arrival sequence of each container, the limited space for container optimization when the density of the storage yard is too high, inaccurate container weight information, temporary changes in voyage or destination port, container sampling inspection and other objective factors and uncontrollable randomness Influenced by factors, the classified storage plan and optimized allocation of specific container locations...

AI Technical Summary

Problems solved by technology

[0011] The purpose of the present invention is to provide a method for pre-turning container export containers before loading in a large container terminal, which overcomes the lack of intelligent optimization decision-making for pre-turning containers in the storage yard in the prior art, resulting in the ubiquity of container flipping during shipping. The problem of low efficiency of shipping boxes
