A?rm stocks a seasonal item that it buys for;$22/unit and sells for $29 unit. During the season, daily demand can be described using a Poisson distribution with a;mean of 2.4. Because of the nature of the item, units remaining at the close of business each day must be removed;at a cost of $2 each. What is the optimum stocking level, and what is the effective service level? 155. Joe's Coffee Shoppe has fresh doughnuts delivered;each morning. Daily demand for plain doughnuts is approximately normal with a mean of 200 and a standard;deviation of 15. Joe pays $1.20 per dozen and has a standing order for 16 dozen. Joe and the staff eat any;leftovers. What is the implied shortage cost? 156. A restaurant prepares Peking Duck daily at a cost;of $18 per duck. Each duck generates revenue of $47 if sold. Demand for Peking Duck can be described by a Poisson;distribution with a mean of 4.2 ducks per day. Unsold ducks at the end of each day are converted to duck;soup at an additional cost of $5 over and above the resulting value as soup. How many ducks should be prepared;each day? 157. A machine is expected to use approximately three;spare parts during its useful life. The spares cost $200 each and have no salvage value or other use. The manager has;ordered?ve spares. Assuming a Poisson usage rate, what range of shortage cost is implied? 158. A manager intends to order a new machine and must;now decide on the number of spare parts to order along with the machine. The parts cost $400 each and have no;salvage value. The manager has compiled a frequency distribution for the probable usage of spare parts, as;shown. For what range of shortage costs would stocking one spare part constitute an optimal decision?Number of The Corner Newsstand has demand for a certain weekly;magazine that can be approximated by a Poisson distribution with a mean of 9.0. Magazines are purchased for;$1.50. 159. If unsold copies can be returned for half;credit and the owner stocks ten copies, what is the implied range of shortage cost? 160. If unsold copies must be destroyed and copies sell;for $4.00 each,?nd the optimum stocking level. 161. If unsold copies can be returned for half credit;and copies sell for $4.25 each,?nd the optimal stocking level. 162. Demand for a component averages 80 units per week;with a weekly standard deviation of demand of 14 units. The current supplier of this component offers a;four-week lead time. Stockout risk is to be kept at 8%. Assume that it costs $50 to hold one unit in inventory for a;year. Suppose the annual cost for the items would be $500 higher if they were purchased from another vendor, but;that vendor would offer a two-week lead time.;Would it be better to go with the more-expensive but;more-responsive vendor?="msonormal">
