SAFETY LEVELThe quantity of material, in
addition to the operating level, required for
continuous operations in the event of interruption
of normal replenishment or unpredictable
fluctuations in issue demand.
SELECTED ITEM MANAGEMENT (SIM)An
inventory control principle which, in
nonautomated ships, focuses management
attention on the small percentage of items that
experience the majority of onboard demands for
material. Inventory management techniques that
apply to repair parts and consumables designated
as SIM items in nonautomated ships are found in
the NAVSUP P-485.
SERVICESNonmaterial requirements such as
equipment, rental, commercial telephone, ferry
tickets, or similar services authorized by proper
authority. For accounting purposes, documents
for services will indicate the appropriate fund
code as shown in NAVSO P-3013.
SIGNAL CODEA single-letter code on a
MILSTRIP requisition that designates who is to
receive the material and who is to pay for it.
SIMSelected Item Maintenance. An inventory
control system by which maximum attention is
given to those items experiencing a high rate of
SIM DTO ITEMAny consumable item that meets
the frequency of demand criteria for a SIM item
but is not stocked by the supply department,
usually because of space limitations. Materials
received are issued immediately to the using
SIM ITEMAn item that has experienced a
frequency of demand of two or more within the
past 6 months or has a predictable demand
frequency of two or more based on deployed or
seasonal usage. (Similar to criteria for terms
peacetime operating stock and demand-based
items used in automated ships.) Frequency of
demand is defined as the number of separate times
an item is issued, regardless of the quantity of each
SPLIT SHIPMENT CODETM code is reserved
for use by transshipment activities. The shipping
activity always assigns code X to the 17th
position. This code is used to indicate that the
increment of the shipment unit (complete or
partial) generated by the shipping activity must be
further divided into two or more increments for
onward movement in separate conveyances, The
transshipping activity identifies each increment
consecutively in the 17th position beginning with
code A. The last increment is always identified
with code Z.
STOCK ARTICLEA collection of like items
within a class.
STOCK-FUNDED SHIPSShips in which the
inventory of general stems and repair parts is
carried in NSA. The ships OPTAR is charged
when material is issued from supply storerooms to
the using departments.
STOCK ITEMConsists of each size or color, et
cetera, of an article.
STOCK UNITThe smallest quantity of a stock item
that can be issued.
STOCKAGE OBJECTIVE The maximum
quantity of material to be maintained on hand to
sustain current operations. It includes the sum of

SUPPLIES AND EQUIPAGE FUNDSThe term

OVERHAUL (SOAP/ILO)The concerted
efforts of assigned shipboard personnel, under the
supervision of ashore-based SOAP/ILO team
members, to refine shipboard inventories of repair
parts; to update related stock records consistent
with prescribed allowances or other stowage
objective criteria; and to identify material
deficiencies and/or excesses. A SOAP/ILO, is
designed to improve the supply readiness of the
ship, entails the offload, identification, and
inventory of shipboard stocks of repair parts,
disposition of excesses, requisitioning of
deficiencies, and the reload and restorage of
allowed items in authorized quantities.
SOAP/ILOs are performed (usually during a
shipyard overhaul) in ships designated and
scheduled by the type commander.
