40) PLEASE HELP WITH THIS! Gentle Ben's Bar and Restaurant uses 5,000 quart bottles of an imported wine each year. The effervescent wine costs $3 per bottle and Is served only in whole bottles because it loses its bubbles quickly. Ben figures that it costs $10 each time an order is placed, and holding costs are 20 percent of the purchase price. It takes three weeks for an order to arrive. Weekly demand is 100 bottles (closed two weeks per year) with a standard devlation of 30 bottles. Ben would like to use an inventory system that minimizes inventory cost and will provide a 95 percent service probability. b. At what inventory level should he place an order? Note: Use Excel's NORM.S.IN( function to find the z value. Round z value to 2 decimal places and final answer to the nearest whole number.

A 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)

NING SYSTEM (ACADEMIC) tory Management - Spring21 Time left 1:14:19 Alocal Omani retail store finds out the its competition is ordering 50O kgs each order of a coffee brand. Over years the local Omani store has realized that its competition has adopted an economic ordering quantity (EOQ) policy for ordering. Whereas, local Omani store has determined that it take OMR 25 to order and the annual holding cost is 25% of the price of the coffee brand. The price of the coffee brand is OMR 100 per kg. What is the annual demand for this coffee brand? Round up to the nearest integer None is correct Ob. 100,000 150,000 O d. 90,000 125.000 NEXT PAGE US PAGE

3. (Ch9) A store has collected the following information on one of its products: Demand = 4,500 units/year Standard deviation of weekly demand = 12 units Ordering costs = $40/order Holding costs = $3/unit/year Cycle-service level = 90% (z for 90% = 1.28) Lead-time = 2 weeks Number of weeks per year = 52 weeks a. If a firm uses the continuous review system to control the inventory, what would be the order quantity and reorder point? b. The firm decided to change to the periodic review system to control the item's inventory. For the most recent review, an inventory clerk checked the inventory of this item and found 300 units. There were no scheduled receipts or backorders at the time. How many units should be ordered? (HINT: Use the EOQ model to derive P, the time between reviews.)
