A communication company is manufacturing mobile phones. Their annual demand is 5,000 mobile sets. They want to determine EOQ for a motherboard which has an annual holding cost (H) of $5/unit, and an ordering cost (S) of $60. They also want to calculate total cost (TC) and the reorder point (R) if the purchasing lead time is 4 days, assuming there are 300 working days per year. Find out: a. Economic Order quantity (EOQ) b. Total cost (TC) c. Reorder point (R)

EOQ, reorder point, and safety stock Alexis Company uses 916 units of a product per year on a continuous basis. The product has a fixed cost of $60 per order, and its carrying cost is $3 per unit per year. It takes 5 days to receive a shipment after an order is placed, and the firm wishes to hold 10 days' usage in inventory as a safety stock. a. Calculate the EOQ. b. Determine the average level of inventory. (Note: Use a 365-day year to calculate daily usage.) c. Determine the reorder point. d. Indicate which of the following variables change if the firm does not hold the safety stock: (1) order cost, (2) carrying cost, (3) total inventory cost, (4) reorder point, (5) economic order quantity. a. Alexis' EOQ is units. (Round to the nearest whole number.)
1 A company decides to establish an EOQ for an item. The annual demand is 100,000 units. The ordering costs are $10 per order, and inventory-carrying costs are $2 per unit per year. Calculate the following: (a). The EOQ in units (b). What is the annual total cost
Suppose that we would like to determine Reorder Point for the product. From the historical data the manager determined demand during lead-time for that product fits Normal distribution with a mean of 200 and standard deviation of 10 products. The maximum stock out risk is 10%. Answer the following questions according to the (Q, R) system. a) Find the safety stock if the lead time is 2 weeks. b) Find the reorder point. c) Find the reorder point if the stock out risk decreases to 1%. Comment on the result.
You are a newsvendor selling the San Pedro Times every morning. Before you get to work, you go to the printer and buy the day’s paper for $0.25 a copy. You sell a copy of the San Pedro Times for $1.00. Daily demand is distributed normally with mean 5 250 and standard deviation 5 50. At the end of each morning, any leftover copies are worthless and they go to a recycle bin. a. How many copies of the San Pedro Times should you buy each morning? b. Based on part (a), what is the probability that you will run out of stock?
The materials manager for a billiard ball maker must periodically place orders for resin, one of the raw materials used in producing billiard balls. She knows that manufacturing uses resin at a rate of 50 kilograms each day, and that it costs $.04 per day to carry a kilogram of resin in inventory. She also knows that the order costs for resin are $100 per order, and that the lead time for delivery is four days. If the order size was 1,000 kilograms of resin, what would be the average inventory level?
Question 1 For supply item ABC, Andrews Company has been ordering 400 units per week. A new purchasing agent has been hired by the company who wants to start using the economic-order- quantity method and its supporting decision elements. She has gathered the following information: Annual demand in units Lead time, in days Ordering costs Insurance and handling costs Purchase price per unit Return on cash investment 20,800 5 $22 $7 $15 15% Required
The company Marombeiro is a commercial representative of a food supplement widely consumed in gyms. The average daily demand for the product is 1,500 units and a standard deviation of 300 units. Average shipping time is 5 days. Of course, if the order is placed at the end of the week, it may take a little longer to receive the shipment, so the standard deviation of the delivery time is 2 days. The unit has a value of R$ 50.00 per unit in stock, an order cost of R$ 50.00 and an annual maintenance fee of 20%. Assume the service level is 99.5%. How much safety stock should the company have? ( )7,500 units ( )19,350 units ( )3,074 units ( )7,916 units
Economics A hospital uses 18,000 of syringes each year. Holding cost per box is $0.60 ordering costs are $96 per order. The hospital buyer would like to take advantage of quantity discounts offered by the supplier. The cost structure is as follows: Number of boxes Price per box 1,000 to 1,999 $1.25 2,000 to 4,999 $1.20 5,000 to 9,999 $1.15 10,000 or more $1.10 Use this data to answer the following: In what level is the EOQ What is the optimal order quantity? What is total cost at each level after the EOQ level?

It is your responsibility, as the new head of the automotive section of Nichols Department Store, to ensure that reorder quantities for the various items have been correctly established. You decide to test one item and choose Michelin tires, XW size 185 × 14 BSW. A perpetual inventory system has been used, so you examine this as well as other records and come up with the following data: Cost per tire $35 each Holding cost 20 percent of tire cost per year Demand 1,000 per year Ordering cost $20 per order Standard deviation of daily demand 3 tires Delivery lead time 4 days Because customers generally do not wait for tires but go elsewhere, you decide on a service probability of 98 percent. Assume the demand occurs 365 days per year. Determine the order quantity. Note: Round your answer to the nearest whole number. Determine the reorder point. Note: Use Excel's NORM.S.INV() function to find the z value. Round z value to 2 decimal places and final answer to the…
