Due to the different shapes and sizes of express parcels, the staff cannot quickly and effectively evaluate the number of vehicles required to load the parcels each time through skimming, resulting in frequent cases that the parcels are not delivered on time as agreed. When unloading, it is necessary to manually check the packages one by one, which is very time-consuming and prone to human error. Problems and abnormal packages cannot be dealt with in time, and packages that have been unloaded need to be manually re-entered into the logistics system.
