Embodiment Construction

[0035] based on the following Figure 1 ~ Figure 4 , specifically explain the preferred embodiment of the present invention.

[0036] Genetic Algorithms (Genetic Algorithms) is a random global search intelligent optimization algorithm developed by the combination of biological genetics theory and genetic theory. Based on genetics, the individual, chromosome, gene, population, fitness, selection, Concepts such as crossover and mutation. Genetic algorithm has the advantages of relatively strong global optimization search ability, fast convergence speed in the iterative process, simple operation process, and strong robustness. The genetic algorithm can be divided into the following steps: 1) coding, initial population generation; 2) fitness function evaluation; 3) selection of parents, population update and optimal search through operations such as crossover and mutation; According to the principle of elimination of the fittest and survival of the fittest, a new population is f...

Abstract

Provided is an integrated scheduling method for key loading and unloading resources of an automatic container terminal. The integrated scheduling method comprises the steps of setting chromosome coding modes, initializing population, defining the fitness function, setting the interlacing operation guideline and the mutation operation guideline, setting the parental generation selection strategy and the filial generation receiving strategy, using the fitness function to conduct chromosome iterative computation, and when meeting the iterative stopping criterion, stopping iteration and outputtingthe optimum solution. The integrated scheduling method can reasonably control device operation and space resource distribution of the container terminal, improves the operation efficiency of the automatic container terminal, reasonably distributes devices and space resources, avoids congestion, shortens the driving time of three types of devices, and optimizes space resource usage of a storage yard.

Description

technical field [0001] The invention relates to an integrated scheduling method for key loading and unloading resources of an automated container terminal, in particular to an automated container terminal QC (quay crane)-AGV (automatic guided vehicle)-ARTG (tyred container gantry crane)-yard space resources integrated scheduling method. Background technique [0002] An automated container terminal is composed of equipment resources and space resources. The scheduling of equipment resources and the optimization of space resources directly determine the operating efficiency of the terminal. [0003] So far, researchers at home and abroad have proposed some integrated scheduling methods for container terminal handling equipment and storage yard space resources. Han, et al studied the problem of yard storage of export containers during loading, deciding how to reserve / allocate yard storage box areas for each ship. The traffic jam of the collection trucks is also considered to ...
