A sporting goods company has a distribution center that maintains inventory of fishing rods. The fishing rods have the following demand, lead time, and cost characteristics: Average demand = 130 units per day, with a standard deviation of 12 units Average lead time = 12 days with a standard deviation of 1 day 250 days per year in the business year Unit cost = $28 Desired service level = 97.5% Ordering cost $53 Inventory carrying cost = 25% a. What is the standard deviation of demand during lead time? b. How many fishing rods should the distribution center carry to provide the desired service level? c. What is the EOQ? d. What is the average cycle stock?

Xemex has collected the following inventory data for the six items that it stocks: ITEM CODE UNIT COST ($) ANNUAL DEMAND (UNITS) ORDERING COST ($) CARRYING COST AS A PERCENTAGE OF UNIT COST 1 10.60 600 40 20 2 11.00 450 30 25 3 2.25 500 50 15 4 150.00 560 40 15 5 4.00 540 35 16 6 4.10 490 40 17 Lynn Robinson, Xemex’s inventory manager, does not feel that all of the items can be controlled.

The production order quantity for this problem is approximately 332 units. daily demand rate = 64; daily production rate = 100. What is the average inventory on - hand ( in other words - the inventory for which you are paying Holding Costs ) In this problem ?

Earthbound Corporation is a manufacturer and distributor of air conditioning systems. You have been engaged to install an accounting system for Earthbound period among the inventory control features earthbound desires as part of the system are indicators of how much to order and when period. The following information is furnished for a product called “Hydronix”  which is carried in inventory: Hydronix are sold by the gross (12 dozen) at a list price of P800 per gross FOB shipper.  John receives a 40% trade discount off list price on purchases in gross lots.  Freight cost is P20 gross from the shipping point to John's plant John uses about 5,000 Hydronix during 259-day production year and must purchase a total of 36 gross per year to allow for normal breakage. Minimum and maximum usages are 12 and 28, respectively. It takes 20 working days (normal delivery time) to receive an order from the date the purchase request is initiated. A rush order in full gross lots can be received by air…

​Sam's Pet Hotel operates 5050 weeks per​ year, 66 days per​ week, and uses a continuous review inventory system. It purchases kitty litter for ​$13.0013.00 per bag.

How much higher will total costs​ be, owing to the distorted EOQ caused by this forecast​ error?

A spice retailer has a lead time of 4 weeks from its supplier of a particular item and the retailer orders every week.  Average weekly demand is normally distributed with a mean of 40 units and standard deviation of 30 units.  a) If it uses an order-up-to level of 301 units, what is its expected ON-HAND inventory? b) If it uses an order-up-to level of 250 units, what is its expected ON-ORDER inventory?  c) If it uses an order-up-to-level of 368 units, what is its in-stock probability? d) For a .96 in-stock probability, what should its order=up-to level be?

GameStop has maintained 75% service level for inventory of PlayStation 5. Mean demand during lead time is 166 PlayStations, and the standard deviation during lead time is 58 PlayStations. The annual cost of carrying one PlayStation in inventory is $12. The store’s operations analyst recently told GameStop's management that they could expect a $550 improvement in profit (based on current figures of cost per PlayStation) if the service level were increased to 97.5%. Is it worthwhile for GameStop to make this change?

As the Manager of Branson’s Department Store, you are responsible for ensuring that reorder quantities for the various items have been correctly established. You decide to test one item and choose product Z. A continuous review inventory policy has been used, so you examine this as well as other records and come up with the following data:   Cost per unit $35 Holding cost 20 percent of unit cost Average daily demand 10 units Ordering cost $30 per order Standard deviation of daily demand 3 units Delivery lead time 4 days   Because customers generally do not wait but go elsewhere, you decide on a service probability of 90 percent. 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.

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)
