Abstract:

Taking the battery swapping system of the automated guided vehicle (AGV) in automated container terminal as the research object, the double finite source closed cycle is used to describe the AGV battery swapping queue and the charging queue. To minimize the total cost under a certain working level, a joint optimization model of battery spare parts and charger configuration is established based on the Markov process. The optimal number of battery spare parts and charging devices can be obtained by the genetic algorithm. The results show that when the number of battery spare parts or charging devices is too small, the penalty cost and profit loss will be high. Compared with the traditional one spare part for one device strategy, the optimal strategy can significantly reduce the total operating cost.

Key words: automated container terminal, automated guided vehicle (AGV), swapping battery, battery spare parts, charger configuration
