Seven. Case analysis: (20 points)
In the 1970s, an automobile factory in Beijing built a high-rise shelf warehouse (that is, an automated warehouse) as an intermediate warehouse to store all kinds of spare parts needed for assembling automobiles. Most of the spare parts needed by this factory are produced by its cooperative units and then transported to the automated warehouse. This factory is one of the earliest enterprises in China to develop automated warehouses.
The warehouse structure is divided into two parts: Takakura and sorting room. Takakura adopts the structure of fixed high shelf and roadway stacker, and there is a roller conveyor between the sorting room and Takakura. When the packaging specifications of the incoming goods do not meet the pallet or standard container, it is necessary to rearrange the packaging of the goods, which is carried out in the sorting room. Because the packaging of various spare parts was not standardized at that time, the workload of finishing work was quite large.
Goods in and out of the warehouse is a man-machine system combining computer control and manual operation. This set of equipment was quite advanced at that time. The warehouse is built in the southeast corner of the factory, far from the assembly workshop. Therefore, it is necessary to transport between the warehouse and the assembly workshop twice, that is, the required parts are delivered from the warehouse, loaded, transported to the assembly workshop and then assembled.
After the completion of the automated warehouse, this advanced facility did not play an ideal role in the production and operation of enterprises. Therefore, its utilization rate has also decreased year by year, and finally it has to be demolished.
Please analyze the following questions:
1. Help enterprises to analyze the reasons why automated warehouse has not played its due role in enterprises.
2. What do we get from it?
