Problem 12-37 (Algo)
A small grocery store sells fresh produce, which it obtains from a local farmer. During the strawberry season, demand for fresh
strawberries can be reasonably approximated using a normal distribution with a mean of 36 quarts per day and a standard deviation of
5 quarts per day. Excess costs run 50 cents per quart. The grocer orders 41 quarts per day.
Use Table.
What is the implied cost of shortage per quart? (Round your z value to 2 decimal places, your service level probability to 4 decimal
places and your final answer to 2 decimal places.)
Shortage cost per quart
Consider a fixed period inventory model. The daily demand of the product has a mean of 30 and standard deviation of 4; orders are placed every 18 days and shipment lead time is 6 days. The store has a service policy of 96%. What is the inventory required?
Red Lip Cherry (RLC) is a local retailer of cherries. During the cherry seasons, daily demand follows a normal distribution with a mean of 100 pounds and a standard deviation of 10 pounds. RLC purchases its cherries from a local orchard for $12 per pound and sells them for $20 per pound. At the end of business day, any remaining cherries will be sold to a producer of cherry juice for $10 per pound.
What is the optimal service level to set?
What is the optimal ordering quantity (corresponding to the optimal service level in Q29)?

- Retailers Warehouse (RW) is an independent supplier of household items to department stores. RW attempts to stock enough items for a 98 percent service probability. A stainless steel knife set is one item it stocks. Demand (2,400 sets per year) is relatively stable over the entire year. Whenever a new stock is ordered, a buyer must ensure that numbers are correct for stock on-hand and then phone in a new order. The total cost involved to place an order is about $5. RW figures that holding inventory in stock and paying for interest on borrowed capital, insurance, and so on, add up to about $4 holding cost per unit per year. Analysis of the past data shows that the standard deviation of demand from retailers is about four units per day for a 365-day year. The lead time to get the order in seven days.a.

Established as a lunch delivery service for offices in 1972 by Wayne and Janet Williams, CKC has grown to be one of the largest catering businesses in Raleigh, North Carolina. The Williams’s divide customer demand into two categories: deliver only and deliver and serve. The deliver-only side of the business delivers boxed meals consisting of a sandwich, salad, dessert, and fruit. The menu for this service is limited to six sandwich selections, three salads or potato chips, and a brownie or fruit bar. Grapes and an orange slice are included with every meal, and iced tea can be ordered to accompany the meals. The overall level of demand for this service throughout the year is fairly constant, although the mix of menu items delivered varies. The planning horizon for this segment of the business is…arrow_forwardIn the following scenario, what will your stockout costs be if you have 200 hammers in stock and you have orders of 80, 60, 50, 30, 120 You are a wholesaler selling hammers.
