≻Demand = 78,000 units/year
≻Ordering cost​ = $30.00​/order
≻Holding cost​ = $3.00​/unit/year
≻Average lead time​ = 1 week
≻Standard deviation of weekly demand​ = 200 units
The answer for a is:
a. The economic order quantity for this item is 1249 units.
​(Enter your response rounded to the nearest whole​ number.)

Petromax Enterprises uses a continuous review inventory control system for one of its SKUS. The following
information is available on the item. The firm operates 48 weeks in a year. Refer to the standard normal table for
Z-values.
> Demand = 52,000 units/year
> Ordering cost = $38.00/order
> Holding cost = $2.50/unit/year
> Average lead time = 1 week
> Standard deviation of weekly demand = 120 units
a. What is the economic order quantity?
The economic order quantity (EOQ) is:
2DS
EOQ =
H '
where D is the demand in units per year, S is the ordering cost, and H is the inventory holding cost.
|2x 52,000 x 38.00
The economic order quantity for this item is
1,257 units.

b. If Petromax wants to provide a 96% service level, what should be the safety stock and the reorder point?
First, the formula for calculating safety stock in a continuous review system is:
ZGGLT, where ogLT = V[.
The standard deviation of weekly demand, og, is given as 120 units. The lead time, L, is given as 1 week.
Using the standard normal table, for the desired service level of 96%, the z value is 1.75.
Therefore, the safety stock is 1.75x 120/ī = 210 units.
Next, calculate demand during lead time, dL, by first calculating weekly demand:
Demand
52,000
Weekly demand, d, is calculated as:
Work Weeks per Year
= 1,083 units.
48
dL is 1,083x1 = 1,083 units.
The reorder point is 1,083 + 210 = 1,293 units.
