The system first adjusts the order structure by optimizing the set delivery fee and the estimated delivery time; after receiving the order, it takes into account factors such as the rider's location, the order in transit, the rider's ability, the merchant's food, the difficulty of delivery, the weather, the geographic road conditions, and the amount of future orders, and then allocates the order to the most suitable rider at the correct time, and at any time during the rider's execution, it prejudges the order overtime and dynamically triggers the re-dispatch operation, achieving the dynamic optimal matching of the order and rider. The company's goal is to achieve the optimal dynamic matching of orders and riders.
