The amount of denim used daily by the Southwest ApparelCompany in its manufacturing process to make jeans isnormally distributed with an average of 4000 yards ofdenim and a standard deviation of 600 yards. The lead timerequired to receive an order of denim from the textile mill
is a constant 7 days. Determine the safety stock and re-order point if the company wants to limit the probability of
a stockout and work stoppage to 5%.
United Airlines has an agreement to buy jet fuel from Exxon. The goal is
to minimize total cost (i.e., ordering cost + holding cost). The annual
demand for fuel is 201,000 barrels. Exxon charges United $3740 to
process each order. United incurs a holding cost of $20 per barrel.
When purchasing using the EOQ (from last question), what is the order cycle
time (days between orders) for United?

Daily demand for fresh cauliflower in the ZZ-Warehouse store follows normal distribution with mean 100 cartons and s.d. 20 cartons.
The ZZ-Warehouse buys at a cost of $50.00 per carton, sells it for $70.00 per carton.
Unsold cartons are sold for $20.00 per carton.
Cost of shortage = 70-50 = 20; cost of excess = 50-20 = 30;
Ratio using (20.1), the service level = (20/(20+30))= 0.4
What is the optimal order quantity, using the single period – continuous demand model?
a. 105
b. 95
c. 110
d. 100
e. 80

- Assume the demand for a companys drug Wozac during the current year is 50,000, and assume demand will grow at 5% a year. If the company builds a plant that can produce x units of Wozac per year, it will cost 16x. Each unit of Wozac is sold for 3. Each unit of Wozac produced incurs a variable production cost of 0.20. It costs 0.40 per year to operate a unit of capacity. Determine how large a Wozac plant the company should build to maximize its expected profit over the next 10 years.arrow_forwardAmong the following multi-period inventory models, which one has the highest probability of stockout?

Mean demand during lead time is 166 PlayStations, and the standard deviation during lead time is 58 PlayStations. The annual cost of carrying one PlayStation in inventory is $12.

Is it worthwhile for GameStop to make this change?arrow_forward
- The materials manager for a billiard ball maker must periodically place orders for resin, one of the raw materials used in producing billiard balls. She knows that manufacturing uses resin at a rate of 50 kilograms each day, and that it costs $.04 per day to carry a kilogram of resin in inventory. She also knows that the order costs for resin are $100 per order, and that the lead time for delivery is four days. If the order size was 1,000 kilograms of resin, what would be the average inventory level?arrow_forwardJohn buys goat milk at a cost of $5 per gallon from a local dairy and sells it for $8 per gallon in its store.

Peter would like to maintain a 95% service level and places an order for 750 packages every time an order is placed. d) If the weekly demand is 186 and there is a 1.5 week lead time - what is the reorder point (99% service level)? e) If the carrying cost per year is $0.50/unit/year - what is the additional cost associate with the 99% service level compared to 95% service level (i.e. cost of safety stock at 99% level - cost of safety stock at 95% service level)?arrow_forward
