MATERIAL MANAGEMENT

Effective material management procedures afloat require personal involvement by supply managers and supervisors in all supply functions. Supervision and training are vital to the supply department's ability to support the assigned operating departments and deployed units. Properly performed tasks, along with keen supervision often results in an effective material management program. Some of these supply tasks are allowance list maintenance, issue control processing, receipt control processing, inventory count procedures, and stock record maintenance.

INVENTORY MANAGEMENT SEGMENTS

The AK basically deals with material inventories consisting of consumables and repairable.

1. Consumables refer to administrative and housekeeping items, tools, forms, repair parts, and other materials consumed by end users.

2. Repairable refer to components, assemblies, subassemblies, and modules determined by the Navy manager as economically repairable when it becomes unserviceable.

Repair parts and consumable segments consist of peacetime operating stock (POS) and non-POS allowance list items, nonallowance POS items, and material scheduled for off-load. Repairable are stock items that, if returned to service through repair cycles, can achieve inventory savings. Some repairable management programs are covered in other chapters of this training manual (TRAMAN).

Allowance List Non-POS Items

Allowance list non-POS items are items carried in

stock based on allowance quantities established in the consolidated shipboard allowance list (COSAL), aviation consolidated allowance list (AVCAL), or load list.

Allowance List POS Items

Allowance list POS items are items carried in stock based on quantities established in the COSAL, AVCAL, or load list plus additional quantities as determined by demand and frequency recorded in the stock records.

Non allowance POS Items

Nonallowance POS items are items carried in stock based on the activity's demand requirements, but not included on any allowance list.

Material Scheduled for Off-Load

Material scheduled for off-load are items in stock but no longer required because of a reduction in allowance quantities or classified as excess material.

OBJECTIVES

The following are some of the basic objectives of inventory control procedures afloat: . Focus attention on very few items that will

satisfy the majority of the onboard demands for material . Maintain an accurate consumption data required

for the 3-M systems program and for maintaining adequate supply levels . Maintain a historical demand data file for not

carried (NC) items . Reduce physical inventory requirements and

prescribe standard inventory procedures l Provide for effective management of controlled

equipage, depot level repairable (DLRs), and presentation silver

STOCK LEVELS

The policy for managing the range and depth of stock material that each ship is required to carry for self-support is describe din OPNAVINST 4441 .12. The average endurance levels of demand based repair parts and equipment related consumables to be carried by an aircraft carrier is 75 days. For nonequipment related, the average endurance level is 60 days. Stock records are grouped as either POS or non-POS for the purposes of levels computation (demand history processing).

Stock levels for non-POS records are established with the requisitioning objective (RO) set equal to the various allowance quantities. The reorder point (RP) is set to one less than the RO, or to a percentage factor of the RO.

Note: The RO is the same as the high limit and the RP is the same as the low limit.

For POS material stock records, the RO and I/Pare computed by SUADPS-RT programs. The RP is equal to the order and shipping level, plus the safety level. The RO is equal to the RP quantity plus the operating level quantity.

SPECIAL MATERIAL MANAGEMENT PROGRAMS

Some of the special material management programs related to inventory management are discussed briefly in the following paragraphs.

Contingency Support Package (CSP)

CSP material is stock material considered essential to mission support of deployed Marine Corps aviation units. Stock records for designated items are identified and material is stored in such a manner that removal and shipment can be done quickly.

Maintenance Support Package (MSP)

MSP materials are small, fast-moving, low-cost, consumable aviation repair parts. MSP material is under the custody of the supply officer and, when possible, should be located near the aircraft intermediate maintenance department (AIMD).

Pre-Expended Bin (PEB)

Materials in the PEB are maintenance-related, high-usage items with a unit cost of $150 or less. However, commanding officers may increase the PEB unit price limit. To qualify as a PEB item, the material must experience three demand frequencies per month. The demand frequency in this case does not necessarily mean the number of times the item is requested from supply, but to the number of times the item is required for maintenance jobs. For example, one transaction of machine screws with a unit of issue of hundred (HD) represents one issue by supply, but may represent several applications to different maintenance jobs. PEB items are expended from supply department records and placed in locations convenient to maintenance personnel on a free issue basis. The quantities of PEB items is limited to one month's supply except for items assigned with a unit of issue (for example, gross) that may exceed the maintenance requirements for one month.

SEAMART

SEAMARTs are established to provide a convenient method of issuing low-cost, high-usage consumable items. Material carried in SEAMART must meet the frequency of demand and unit price limits established by the ship's supply officer. TYCOM approval is required to establish a SEAMART.

Aviation Fly-In Support Package (FISP)

Materials in the FISP consist of selected aviation repair parts that accompany aircraft deploying to an amphibious operating area. The purpose of the FISP is

to provide temporary organizational level supply support until such time that intermediate level facilities and materials become available. Material in the FISP is in addition to normal AVCAL allowances. The FISP is maintained as a protected stock asset by Marine Corps aircraft groups (MAGs) that provide aircraft to the maritime prepositioned ship's marine amphibious brigade aviation combat element.

Maintenance Assistance Modules (MAMs)

The MAMs are replaceable assemblies required to execute approved maintenance plans that call for progressive or selected module substitution. The MAMs are considered as DLRs and are under the management control of the supply officer, but may be located in the operating and maintenance spaces under the subcustody of the operating or maintenance personnel.

Test Bench Installations (TBIs)

The TBIs are similar to MAMs. They are DLRs installed within a test bench and used as part of the test bench to isolate faults. The initial requirements for TBIs are identified during the AVCAL process but are not included as part of the freed allowance. The TBIs are issued to the custody of the intermediate maintenance activity (IMA) by the supply officer.

Controlled Equipage

Controlled equipage refers to those items of equipage that require special management control. Refer to Appendix II of NAVSUP P-485 for a list of items classified as controlled equipage.
