Method and system for analyzing process load of car body rack warehouse

A method for analyzing a process load of a car body rack warehouse, performing the following steps through a processor comprising a computing device:

• S1, collecting sample data of car body rack warehouses of i car factories, the sample data comprising initial geometric dimension data of a goods case and the maximum stock mass Mi of the goods case by a user;
• S2, forming a second geometric dimension data of the goods case, the second geometric dimension data of the goods case comprising transverse column spacing Li, longitudinal column spacing Bi, and a floor height Hi, unifying units of the maximum stock mass of the goods case, and converting mass to weight through standard gravitational relationships and obtaining the maximum stock weight Gi of the goods case by calculation by using the computing device;
