A pharmacist is trying to determine the inventory order and stock levels for a particular drug. The following information is available about the drug.
Demand (D)
85 tablets/week
Working weeks per year
52 weeks
Unit holding cost per year (H)
$6
Order cost (S)
$44/order
Standard deviation of weekly demand (sd)
15 tablets
Lead time (L)
2 weeks
Desired cycle service level
95%
If the pharmacist uses the continuous review (Q) system to control the inventory of the drug, what would be the order quantity and reorder point?
If the pharmacist uses the periodic review (P) system to control the inventory of the drug, what would be the review interval and target inventory level? (Hint: Use the EOQ model to derive the review interval P)
Wear A Mask (WAM) uses a continuous review system and operates
52 weeks per year. One of the SKUs has the following
characteristics.
▪ Demand (D) = 20,600 units/year
▪ Ordering cost (S) = $55.00/order
Holding cost (H) = $4.4/unit/year
▪ Lead time (L) = 3 week(s)
Cycle-service level = 90%, z = 1.28
H
.
▪ Demand is normally distributed, with a standard deviation of
weekly demand of 103 units.
▪ Current on-hand inventory is 1,040 units, with no scheduled
receipts and no backorders.
