5-4.9 Positioning Not all items are stored in the main stockroom. Sometimes it is more advantageous for items to be stored in other locations. The decision on where to place items is called “positioning.” Locations to store material include: Centralized locations — national or regional storage areas positioned to provide timely, but cost-effective services to supported areas. Plant or facility locations — stockrooms and storage space in direct support of a specific site. Remote locations — located away from the main stockroom. Satellite locations — consist of predetermined quantities of parts and supplies located in Postal Service installations for distribution to a repair activity away from the main stockroom. These can be fixed locations or mobile stock locations.
