Question
•••• 12.40 A gourmet coffee shop in downtown San Francisco is open 200 days a year and sells an average of 75 pounds of Kona coffee beans a day. (Demand can be assumed to be distributed normally, with a standard deviation of 15 pounds per day.) After ordering (fixed cost = $16 per order), beans are always shipped from Hawaii within exactly 4 days. Per- pound annual holding costs for the beans are $3.
- a. What is the economic order quantity (EOQ) for Kona coffee beans?
- b. What are the total annual holding costs of stock for Kona coffee beans?
- c. What are the total annual ordering costs for Kona coffee beans?
- d. Assume that management has specified that no more than a 1% risk during stockout is acceptable. What should the reorder point (ROP) be?
- e. What is the safety stock needed to attain a 1 % risk of stockout during lead time?
- f. What is the annual holding cost of maintaining the level of safety stock needed to support a 1 % risk?
- g. If management specified that a 2% risk of stockout during lead time would be acceptable, would the safety stock holding costs decrease or increase?

Practice Question:
1. A small local pharmacy, Tacky Pharm sells self-test kits for diabetic patients. These kits cost Tacky $15 each. Customers want to buy the kits at a rate of 240 per week. The pharmacy operates 52 weeks per year. Tacky Pharm estimates ordering cost at $50. Annual holding costs are 20 percent of the unit cost. Lead time is 2 weeks. Using the information given,
(1) Calculate the economic order quantity.
(2) Calculate the total annual costs using the EOQ.
(3) Determine the reorder point.
Question 5 Safety Stock Model
Consider the following information on an inventory management system (one year is 50 weeks, one year is 365 days and 1 week is 7 days):
Item Cost:$10
Order Cost:$250
Annual Holding Cost:33% of item cost
Average Demand:515 per week
Std. Dev. of Demand:125 per week
Lead time:14 days
a) Ignoring the uncertainty in the demand (i.e. looking only at average values), find the optimal order quantity and the reorder point.
b) Consider now the uncertainty. The order quantity remains the same. If the target is to have a 98% annual service level, what should be the ROP? What is the safety stock?
c) If the ROP is 1178 units (note that z value has been changed), what is the corresponding annual service level that the firm can provide?

- Question 4 Illustrate Guardian pharmacy’s reorder system to manage their inventory so meet customer expectation. answer guidelines To use order point system and periodic review system. Illustrate its characteristics/advantage in the context of managing inventory in a pharmacy. For example: 1. Order point system - When the quantity of an item on hand in inventory falls to a predetermined level, an order is placed. • The quantity ordered is based on economic order quantity (EOQ). • Order quantity are usually fixed. • The order point is determined by the average demand during the lead time. • If the average demand or the lead time changes, there is no corresponding change in the order point, effectively there is a change in the safety stock. • The interval between replenishment are not constant but vary depending on the actual demand during the order cycle. Usually used for stocks that are longer to sell from the store so to…arrow_forwardQuestion: The purchasing agent for a company that assembles and sells air- conditioning equipment in a Latin American country noted that the cost of compressors has increased significantly each time they have been reordered.
