Chapter 9, Problem 27P
In a P system, the lead time for a box of weed-killer is 2 weeks and the review period is 1 week. Demand during the protection interval averages 218 boxes, with a standard deviation of 40 boxes.
- What is the cycle-service level when the target invent tory is set at 300 boxes?
- In the fall season, demand for weed-killer decreases but also becomes more highly variable. Assume that during the fall season, demand during the protection interval is expected to decrease to 180 boxes, but with a standard deviation of 50 boxes. What would be the cycle-service level if management keeps the target inventory level set at 300 boxes?

Barbara Flynn is in charge of maintaining hospital supplies at General Hospital. During the past year, the mean lead time demand for bandage BX-5 was 60 (and was normally distributed). Furthermore, the standard deviation for BX-5 was 7. Ms. Flynn would like to maintain a 90% service level. Refer to the standard normal table for z-values.
a) What safety stock level do you recommend for BX-5?
Safety stock =units (round your response to the nearest whole number).
b) What is the appropriate reorder point?
Reorder Point =units (round your response to the nearest whole number).
Your company currently keeps a safety stock of 554 units of a particular product that has a lead time of 10 days. Records indicate that the weekly demand was as follows:
1176
955
780
1052
736
842
748
993
852
738
794
1444
1333
1372
1106
706
923
734
786
729
1357
1165
1277
683
1106
What is the current service level? Input your result as the decimal form and round to 4 decimal places.
You are requested to recommend a safety stock that will ensure an average service level of 97.5%. The lead time is not expected to change. What safety stock would you recommend? (0 decimal places)
Annual demand is 16000 units, cost per order is $75 and carrying cost per unit as a percentage is 10%. The company works 250 weeks a year; the lead-time on all orders placed is 6 working days.
Assuming constant lead-time demand, and a unit cost of $45 what is the economic order quantity? What is the reorder point.
If lead-time demand shows variability that follows a normal distribution with a mean μ =420 and a standard deviation σ =20, what will the revised reorder point if two stock-outs (shortages) are allowed?
What is the company’s reorder point if the probability of a stock-out on any cycle is restricted to 0.05?

- GameStop has maintained 75% service level for inventory of PlayStation 5. 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.

Assume that daily demand is approximately normally distributed with mean of 150 units and a standard deviation of 30 units. a. What is your recommended daily order quantity for the supermarket? B.How likely the supermarket will experience a stock-out for this dairy product? C.In problems such as these, why would the supplier offer a rebate as high as $1?

What happens to the supermarket order quantity as the rebate is reduced?arrow_forward40 Gentle Ben's Bar and Restaurant uses 5,000 quart bottles of an imported wine each year. The effervescent wine costs $3 per bottle and is served only in whole bottles because it loses its bubbles quickly. Ben figures that it costs $10 each time an order is placed, and holding costs are 20 percent of the purchase price. It takes three weeks for an order to arrive. Weekly demand is 100 bottles (closed two weeks per year) with a standard deviation of 30 bottles. Ben would like to use an inventory system that minimizes inventory cost and will provide a 95 percent service probability. a. What is the economic quantity for Ben to order?
