THE YOUNG AVAILABLE DAILY INJECTION QUANTITY

 

%YMAC = Current Inventory/YMAC

 

------------------------------------

%YMDIQ Calculation

 

If the %YMAC is < 100% and > 0%

then use the FORMULA to find the %YMDIQ (1)

 

FORMULA (2,3):

%YMDIQ = 100.0 - (%YMAC * 1.0111774) + (%YMAC^2 * 0.0051126)

 

------------------------------------

YADIQ Calculation (4)

 

YADIQ = (%YMDIQ/100) * YMDIQ

Round to the nearest whole Dekatherm (an integer)

 

------------------------------------

 

Notes: (1) The formula applies only when inventory is < than YMAC

and > 0. If inventory is > or = to YMAC, then set YADIQ

= 0. If inventory is < or = 0, set YADIQ = YMDIQ.

 

(2) In the context of this formula, the %YMAC and %YMDIQ

values are taken as whole numbers, and not as decimal

only numbers (i.e. if the value is 40% use 40.0 not .40,

or if it is 36.1234% use 36.1234 not 0.361234).

 

(3) The coefficients are entered with seven decimal places.

The table is calculated with seven decimal places, and

then rounded for display purposes.

 

(4) All calculations are initially performed utilizing seven

decimal places. The final YADIQ, however, is rounded to

the nearest whole number.
