- The chapter presented various approaches for the control of inventory investment. Discuss three additional approaches not included that might involve supply chain managers.arrow_forwardA pharmacist is trying to determine the inventory order and stock levels for a particular drug. The following information is available about the drug. Demand (D) 85 tablets/week Working weeks per year 52 weeks Unit holding cost per year (H) $6 Order cost (S) $44/order Standard deviation of weekly demand (sd) 15 tablets Lead time (L) 2 weeks Desired cycle service level 95% If the pharmacist uses the continuous review (Q) system to control the inventory of the drug, what would be the order quantity and reorder point? If the pharmacist uses the periodic review (P) system to control the inventory of the drug, what would be the review interval and target inventory level? (Hint: Use the EOQ model to derive the review interval P)arrow_forwardSam's Pet Hotel operates 52 weeks per year, 6 days per week, and uses a continuous review inventory system.

- University Drug Pharmaceuticals orders its antibiotics every two weeks (14 days) when a salesperson visits from one of the pharmaceutical companies. Tetracycline is one of its most prescribed antibiotics, with average daily demand of 2,000 capsules. The standard deviation of daily demand was derived from examining prescriptions filled over the past three months and was found to be 800 capsules. It takes five days for the order to arrive. University Drug would like to satisfy 99 percent of the prescriptions. The salesperson just arrived, and there are currently 25,000 capsules in stock. How many capsules should be ordered?arrow_forwardIt takes approximately 2 weeks (14 days) for an order of steel bolts to arrive once the order has been placed. The demand for bolts is fairly constant; on the average, the manager, Michelle Wu, has observed that the hardware store sells 500 of these bolts each day. Because the demand is fairly constant, Michelle believes that she can avoid stockouts completely if she orders the bolts at the correct time. What is the reorder point? The reorder point is? units (enter your response as a whole number).arrow_forwardCharlie's Pizza orders all of its pepperoni, olives, anchovies, and mozzarella cheese to be shipped directly from Italy. An American distributor stops by every six weeks to take orders. Because the orders are shipped directly from Italy, they take five weeks to arrive. Charlie's Pizza uses an average of 160 pounds of pepperoni each week, with a standard deviation of 26 pounds. Charlie's prides itself on offering only the best-quality ingredients and a high level of service, so it wants to ensure a 99 percent probability of not stocking out on pepperoni. Assume that the sales representative just walked in the door and there are currently 500 pounds of pepperoni in the walk-in cooler. How many pounds of pepperoni would you order? (Use Excel's NORMSINV() function to find the correct critical value for the given a-level. Do not round intermediate calculations. Round "z" value to 2 decimal places and final answer to the nearest whole number.) Amount of pepperoni's ordered poundsarrow_forward
- Charlie’s Pizza orders all of its pepperoni, olives, anchovies, and mozzarella cheese to be shipped directly from Italy. An American distributor stops every four weeks to take orders. Because the orders are shipped directly from Italy, they take three weeks to arrive. Charlie’s Pizza uses an average of 150 pounds of pepperoni each week, with a standard deviation of 30 pounds. Charlie’s prides itself on offering only the best quality ingredientsand a high level of service, so it wants to ensure a 98 percent probability of not stocking out on pepperoni.

You decide to test one item and choose product Z.

Assume that Branson’s Department Store operates 320 days per year. [What is the annual demand (D)? Determine the optimal order quantity, Q*. Determine the reorder point (R) if demand is constant. Determine the reorder point (R) if demand is varies.arrow_forwardSam's Cat Hotel operates 50 weeks per year, 6 days per week, and uses a continuous review inventory system.
