CHAPTER 8
INVENTORY MANAGEMENT
As you study this chapter you will learn that the term
inventory management means more than just physical
inventory. Inventory management requires control of
and agreement between stock and stock records,
accurate control procedures, evaluating usage, and
anticipating requirements.
INVENTORY CONTROL PROCEDURES
Some inventory procedures were discussed in an
earlier chapter. In addition, inventory control
procedures mean providing for the availability of
material, where, when, and in the kind and quantities
required. It means balancing requests against available
funds and purging storerooms of stock no longer
applicable to installed equipment or in unserviceable
condition. It means knowing the best levels of supply to
be maintained and developing a sound review procedure
to make sure supply adjustments are timely and
accurate.
INVENTORY MANAGEMENT SEGMENT
Shipboard material inventories are divided into five
segments for management purposes. These five
segments that are discussed in the following paragraphs
are operating space items (OSIs), repair parts,
consumables, maintenance assistance modules
(MAMs), and ready service spares (RSSs).
Operating Space Items
OSIs are those items in the custody and under the
management of various department heads aboard your
ship. This type of material was designated OSI by your
ship’s COSAL. Some of this material can require special
inventory control and can be designated as controlled
equipage.
Repair Parts
Repair parts are in the custody of the supply officer
when supply department storage space permits and are
always under his or her management.
Consumables
Consumables are in the custody of the supply officer
when storage permits. You can carry a small amount of
consumables such as cleaning supplies, various amounts
of office supplies, and some paint. Stocked consumables
(items carried as supply department stock) are managed
by the supply officer whether such items are stored in
supply department spaces or in other department spaces.
Remember, you need the approval of the commanding
officer to store your stock in another department’s
spaces. All nonstocked consumables are in the custody
and under the management of the other department
heads.
Maintenance Assistance Modules
MAMs are usually in the custody of the appropriate
department head and should be located in the
appropriate operating and maintenance spaces under the
subcustody of operating/maintenance personnel.
MAMs are replaceable modules required to execute an
approved maintenance plan that calls for identifying the
fault of a failed module through progressive or selective
module substitution. MAMs will appear in your
COSAL. When a MAM has replaced a bad one in the
equipment, that department or work center is required
to submit the proper paper work to the supply
department to replace the one actually used.
Ready Service Spares
RSSs are repair parts that are in the custody of the
appropriate department head. These repair parts and
spares are designated by the Hardware Systems
Command during maintenance engineering analysis to
be stored in or near certain equipment for
troubleshooting and for effecting rapid equipment
repairs. These spares will appear in your COSAL and
may also appear in section IIIA of your COSAL as items
that you could stock if usage warrants as backup.
