- The average daily demand and standard deviation of daily demand for a product is 800 and 12 respectively. Replenishment lead time from the supplier in 4 days. The fixed cost and holding st are $15,000 and $18, respectively.If the service level is 95% then calculate a) Average demand during lead time b) Safety stock c) Reorder level d) Order quantityarrow_forwardSurge Electric uses 4,000 toggle switches a year. Switches are priced as follows: 1 to 499, 90cents each; 500 to 999, 85 cents each; and 1,000 or more, 80 cents each. It costs approximately$30 to prepare an order and receive it, and carrying costs are 40 percent of purchase price perunit on an annual basis. Determine the optimal order quantity and the total annual cost.arrow_forwardHappy Pet, Inc., is a large pet store located in LongBeach Mall. Although the store specializes in dogs, it a lso sellsfish, turtle, and bird supplies. The Everlast Leader, a leather leadfor dogs, costs Happy Pet $7 each. There is an annual demand for6,000 Everlast Leaders. The manager, Stephan Wagner, has determinedthat the ordering cost is $20 per order and the carrying cost,as a percentage of unit cost, is 15%. Happy Pet is now consideringa new supplier of Everlast Leaders. Each lead would cost only$6.65, but, in order to get this discount, Happy Pet would have tobuy shipments of 3,000 at a time. Should Happy Pet use the newsupplier and take this discount for quantity buying?arrow_forward
- Palin’s Muffler Shop has one standard muffler that fits a large variety of cars. The shop wishes to establish a periodic review system to manage inventory of this standard muffler. Use the information in the following table to determine the optimal inventory target level (or order-up-to level). Annual demand 2,750 mufflers Ordering cost $ 35 per order Standard deviation of daily demand 6 mufflers per working day Service probability 76 % Item cost $ 28.00 per muffler Lead time 4 working days Annual holding cost 22 % of item value Working days 275 per year Review period 21 working days a. What is the optimal target level (order-up-to level)? If the service probability requirement is 93 percent, the optimal target level will: Increase Decrease Stay the samearrow_forwardTaylor Supply is a wholesaler of office supplies and equipment. Taylor purchases cartons of staples from Barker Manufacturing. Barker offers a price of $7 per carton of staples. Taylor incurs a fixed charge of $90 per order to cover order equipment and clerical costs. Each order takes 3 days to arrive. Taylor has projected sales to be 603 boxes per day. Taylor's accounting department has determined the holding costs relevant for inventory decisions are 28% of unit cost. Assume Q=3000. If Taylor wants a 90% service level, and the standard deviation in daily demand is 250, what is their average inventory?arrow_forwardA medical facility’s demand for N95 respirators and disposable gloves is deterministic and stable at a rate of 20 respirators per day and 100 gloves per day. The distributor charges $20 per pack of 20 respirators and $10 for a pack of 25 gloves. The distributor offered the healthcare facility the following plan: whenever the medical facility places a single order for both N95 respirators and gloves, the distributor will package one pack of respirators together with two packs of gloves to minimize shipping volume. The remainder of the order of gloves will be sent in the second shipment (without any extra shipping cost), which will be timed so that the healthcare facility receives the second shipment just before it runs out of gloves inventory. The shortages are not allowed. The fixed cost of placing an order is $10 and the holding cost rate is a 20% annual interest rate (assume 365 days per year). Calculate the average annual cost for this inventory system. If the lead time from the…arrow_forward
- Red Lip Cherry (RLC) is a local retailer of cherries. During the cherry seasons, daily demand follows a normal distribution with a mean of 100 pounds and a standard deviation of 10 pounds. RLC purchases its cherries from a local orchard for $12 per pound and sells them for $20 per pound. At the end of business day, any remaining cherries will be sold to a producer of cherry juice for $10 per pound. What is the optimal service level to set? What is the optimal ordering quantity (corresponding to the optimal service level in Q29)?arrow_forwardThe Co-op in problem 6 has discovered that it should establish a safety stock for its sweatshirts. It wants to use a reorder point system with a two-week lead time. The demand over a two-week interval has an average of 450 units and a standard deviation of 250 units.a. What reorder point should the Co-op establish to ensure a 95 percent service level for each order placed?b. What reorder point should be established to ensure that no more than one stockout occurs in the course of a year?c. How much average inventory will the Co-op carry for part b? Include both cycle inventory and safety stock in your answer.d. How often will the Co-op turn over its inventory, using the results from part c?arrow_forwardKabel Market store sells electric cable. The demand for cable is normally distributed. The inventory related information at Kabel Market is as follows: Average Annual Demand = 16,900 meters Standard deviation of weekly demand = 28 meters Cable selling price = AMD 640.00 per meter Ordering cost = AMD 1,250.00 per order Lead time = 5 weeks Annual inventory-holding cost estimate = 2.5% of the cable selling price Required service level = 95% Kabel Market works 52 weeks a year. Note: The approximate z values are: for 0.9 ≈ 1.28, for 0.92 ≈ 1.405, for 0.95 ≈ 1.645, for 0.98 ≈ 2.05. Suppose the bar management practices the fixed-QUANTITY ordering system with the use of the economic order quantity. Answer the following questions: (i) How many meters of cable they order from the supplier each time? (ii) When do they place an order? (iii) What is the safety stock?arrow_forward
- KVS Pharmacy fills prescriptions for a popular children’santibiotic, Amoxycilin. The daily demand for Amoxycilinis normally distributed with a mean of 200 ounces and a standard deviation of 80 ounces. The vendor for the phar-maceutical firm that supplies the drug calls the drug-store’s pharmacist every 30 days and checks the inventory of Amoxycilin. During a call the druggist indicated thestore had 60 ounces of the antibiotic in stock. The leadtime to receive an order is four days. Determine the order size that will enable the drugstore to maintain a 99% ser-vice level.arrow_forwardSam's Pet Hotel operates 52 weeks per year, 6 days per week, and uses a continuous review inventory system. It purchases kitty litter for $13.00 per bag. The following information is available about these bags: ≻Demand=75 bags/week ≻Order cost=$55.00/order ≻Annual holding cost=25 percent of cost ≻Desired cycle-service level=80 percent ≻Lead time=4 weeks (24 working days) ≻Standard deviation of weekly demand=15 bags ≻Current on-hand inventory is 320 bags, with no open orders or backorders. Part 2 a. Suppose that the weekly demand forecast of 75 bags is incorrect and actual demand averages only 50 bags per week. How much higher will total costs be, owing to the distorted EOQ caused by this forecast error? The costs will be $enter your response here higher owing to the error in EOQ. (Enter your response rounded to two decimal places.) a. What is the EOQ? What would the average time between orders (in weeks)? b. What should R be? c.

On Monday, at ordering time, a clerk found 112 bags of seed in stock, and so he ordered 198 bags. Daily demand for grass seed is normally distributed with a mean of 15 bags and a standard deviation of four bags.The manager would like to know what the probability is that a grass seed stockout will occur before the next order arrives.
