Abstract: An order processing system includes a computing device, which includes a processor and a storage device storing computer executable code. The computer executable code, when executed at the processor, is configured to: receive an order, determine a cool-down period of the order based on a cost function, and dispatch the order to a warehouse platform when the cool-down period expires. The cost function takes into account at least a waste cost due to process by the warehouse platform according to the order in case of possible cancellation of the order after the cool-down period and a delay cost due to delayed dispatching of the order to the warehouse platform by the cool-down period. The cool-down period is determined as one that minimizes the cost function in a prescribed range.
