Suppose that the R&B Beverage Company has a soft drink product that shows a constant annual demand rate of 3650 cases. A case of the soft drink costs R&B $4. Ordering costs are $25 per order and holding costs are 26% of the value of the inventory. R&B has 250 working days per year, and the lead time is 5 days. Identify the following aspects of the inventory policy:
Solution:
Holding cost = $4 x 0.26 = $1.04
a. The economic order quantity, Q* is calculated using the formula:-
Q* =
2 x Annual Demand x Ordering cost/Holding cost
Q* =
2 x 3,650 x 25/1.04
Q* = 418.9 approx 419

b. The reorder point, r is calculated using the formula:
r = Average daily usage x Lead time
r = 3650/250 x 5
r = 73 units
--------------------------------------------------------------------------------------------
c. The cycle time, T is calculated using the formula:
T = Q*/Annual demand x Number of working days per year
T = 490/3650 x 250
T = 33.56 days
----------------------------------------------------------------------------------------------
d. The total annual cost, TC is calculated using the formula:
TC = Total annual demand x Cost per unit + Ordering cost + Storage cost
TC = (3,650 x $4) + (3,650/419 x $25) + (3,650 x 1.04)
TC = $18,613.8
