Answer 1.
Annual usage = 25,000 containers
Annual carrying cost per container = $3
Ordering cost per order = $9
Economic order quantity = (2 * Annual usage * Ordering cost per
order / Annual carrying cost per container)^(1/2)
Economic order quantity = (2 * 25,000 * $9 / $3)^(1/2)
Economic order quantity = 150,000^(1/2)
Economic order quantity = 387 containers
Answer 2.
Average daily usage = 60 containers
Lead time = 4 days
Reorder point = Average daily usage * Lead time
Reorder point = 60 * 4
Reorder point = 240 containers
Answer 3.
Average daily usage = 60 containers
Lead time = 4 days
Safety stock = 25 containers
Reorder point = Average daily usage * Lead time + Safety
stock
Reorder point = 60 * 4 + 25
Reorder point = 265 containers
