Goods yard structure control method and device

A goods yard structure control device, characterized in that the device comprises:

• a computing module for determining busyness of staff based on a ratio of an amount of goods arrived to be shelved to a current number of the staff in a goods yard;
• a first control module for outputting, when the busyness is above a first preset value, an instruction for controlling the goods to be shelved randomly;
• a second control module for determining, when the busyness is between the first preset value and a second preset value, a sale popularity level to which the goods belong, and then outputting an instruction for controlling the goods to be shelved to a shelf corresponding to the sale popularity level of the goods, wherein the first preset value is greater than the second preset value;
• a third control module for determining, when the busyness is below the second preset value, a sale popularity level to which the goods belong, and then judging whether a current remaining space of a shelf corresponding to pre-selected goods of a higher sale popularity level is enough to accommodate the arrived goods of the higher sale popularity level, if so, then outputting an instruction for controlling the goods to be shelved to the shelf corresponding to the sale popularity level of the goods;
• otherwise, determining goods of a lower sale popularity level to be withdrawn from a shelf according to a preset strategy, and then outputting an instruction for controlling the goods of the lower sale popularity to be withdrawn from the shelf and outputting an instruction for controlling the goods of the higher sale popularity level to be shelved to the shelf on which the goods of the lower sale popularity level were shelved prior to being withdrawn.
