Question

what means assembly Warehouse?

Answer 1

For better understanding first, you need to know the following terms:

Manufacturing: It is the process of producing a final product from the unprocessed or semi-processed material.
Assembly: It is the process of assembling, accumulation, putting together, a final product from the finished parts or partially assembled units.
Warehouse: A large building/storage house where raw materials and manufactured goods are being stored prior to distribution for sale.

So now it is clear that

Assembly Warehouse: It is a place/ building/ plant/ house where finished parts of a final product are assembled and put together from different units which are located remotely to each other or from the single units.
Let's take an example of automobile manufacturing(Car); where the engine is made in location A, wheels may produce in location B, production of staring took place in location C, and seat covers in location D. So all these part are assembled in one location for the final production of Car which is called the assembly Warehouse.
