The following 3-part exercise is based on the Operations Management topic of Inventory Cost: Reminder: If a Q is given, use that. If not then calculate EOQ. 1) Each week you sell 18 desks. You order 51 desks at a time. Each order costs you 52 in labor to order, check in, store and pay the invoice. You sell each desk for $57 in profit. What are your annual ordering costs? 2) Each month you sell 1,106 couches. Your order couches in truckload quantities of 325 and estimate that each truck costs you $55 to unload and put away. You estimate that the storage space for one couch is worth $6.90 monthly. What is your annual holding cost? 3) Each year you consume 3,014 pounds of butter in your restaurant and pay an average of 3.27 for each pound. You estimate a pound of butter costs 8.76 per month to store in your refrigerator. You order butter in quantities of 54 pounds and estimate it costs you 6.99 to unload and…

Demand for walnut fudge ice cream at the Sweet Cream Dairy can be approximated by a normaldistribution with a mean of 21 gallons per week and a standard deviation of 3.5 gallons per week.The new manager desires a service level of 90 percent. Lead time is two days, and the dairy isopen seven days a week. (Hint: Work in terms of weeks.) b. If a fixed-interval model is used instead of an ROP model, what order size would be needed forthe 90 percent service level with an order interval of 10 days and a supply of 8 gallons on handat the order time? What is the probability of experiencing a stockout before this order arrives?
