Library-crossing jobs can be divided into four types by different enterprise types:
First, the manufacturing type is more library
Receiving and integrating the incoming supply is for on-time manufacturing.For example, a manufacturer may establish the warehouse near the plant and use it as a distribution place to prepare parts or integrate supporting components.Since the requirements can be predicdirectly predicted from the MRP system, the parts arrive at the warehouse and transported directly to the workshop without storage.
Second, the sales type more database

Integrate the goods from different suppliers to the same customer, sorted and packaged, and shipped directly to each retailer.For example, computer distributors typically integrate and pack parts from different manufacturers in time according to customer order needs, and transport a vehicle to a customer's designated location.
Three, the type of transit database
Many logistics companies put together goods from different customers to gain economies of scale, repackaging various loads of transport and small packaging goods to the warehouse to facilitate one-load shipment to save shipping costs.

Four, the retail type more database
After obtaining the goods from multiple suppliers, the goods are sorted and loaded in the warehouse according to the advance orders from each retail store and shipped directly to each retail store.
The common characteristics of the four library operation types mentioned above are cargo integration and a very short cycle, which makes this very short cycle possible mainly because the destination is known before the goods are received.Therefore, the library operation can also be divided into two types: before and post distribution according to the information.
