The US group's take-out backstage will make a global analysis of information such as riders, orders and merchants, and make matching decisions. Try to choose riders who have plenty of delivery time and pass by. However, in areas with dense viaducts and poor indoor signal, it is still difficult to identify the exact location of the rider, which may lead to unreasonable distribution, resulting in the rider not being able to complete the distribution according to the estimated time. For this problem, Meituan Takeaway has some solutions, such as "transferring orders" and "reassigning", and will continue to increase investment in technology research and development to overcome the information blind spot brought about by offline complex situations.
