(2) Use the six most recent replenishment receipts for an item to compute the
average OST.
(a) Exclude PD 01-08 requisitions and requisitions with long delays from
wholesale backorder, unusual circumstances, or lack of funds.
(b) Subtract the requisition document date from the date the receipt is
posted for each of the six receipts. Add results and divide by six. Round up any fraction
to a whole day.
(3) Enter the result of the OST computation on line 3.
h. Lines 4 through 9. These lines are not used to do a DOS computation; leave
them blank.
i. Lines 10 and 11. Enter the reorder point (ROP) quantity on line 10 and the RO
on line 11.
(1) For units in CONUS, refer to Extract 1, Table G-2, page Extract 1-7.
These units have been assigned 15 DOS as an operating level (OL) and 5 DOS as an
stockage level/ safety level (SL).
(2) For units outside CONUS (OCONUS), use Extract 1, Table G-3, page
Extract 1-7, for other than class 9 [air line of communications (ALOC)] and Extract 1, Table
G-20, page Extract 1-8, for class 9 (ALOC). These units have been assigned 30 DOS as
an OL and 15 DOS as an SL for other than class 9 (ALOC); 5 DOS as an SL for class 9
(ALOC).
(3)
Go to the appropriate table. Refer to Extract 1.
(a) Find the quantity demanded during the control period (entry on line 2)
at the top of the table.
(b)
Find the OST (entry line 3) at the left side of the table.
(c) Follow both lines until they meet. This block contains the ROP and
the RO as well as the RO + OST.
(d)
Enter the ROP on line 10 and the RO on line 11.
(e) Refer to the example shown in figure 1-13. Extract 1, Table G-3, is
utilized to determine the ROP and RO. For the quantity demanded in June 1990 (228)
and the OST (25), you find the quantity in the column of 217-228 and the OST in the 21
THRU 25 row. When you find the intercept point, you find the ROP is 23 and the RO is 42
as shown on lines 10 and 11.
