Study the quantity of handling robots for picking operation considering charging

With the gradual expansion of e-commerce business scale, the warehouse picking operation is facing the production pressure of constant delivery time and increasing business volume. Therefore, enterprises need to adjust the resource allocation in the picking operation in time according to the order changes to ensure the order production efficiency. The handling robot is one of the resources that can be flexibly adjusted and directly affect the production time in the picking operation, so this paper considers adjusting the configuration of the handling robot. Due to the high unit price of the robot and the need to charge in the process of use, the enterprise also needs to balance the production efficiency and equipment cost. In addition, scheduling other robots during robot charging will also affect the number of robots. Therefore, this paper studies the number of handling robots in the picking operation considering charging, in order to ensure the production efficiency and reduce the cost of picking operation.
