- 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?The annual demand, ordering cost, and the annual inventory carrying cost rate for a certain item are 600 units, Quantity 1 to 49 50 to 249 250 and up Price $5.00/unit $4.50/unit $ 4.10/unit $20/order and 30% of item price, respectively. (a) Assume the discounts applied to all the units in the order, what should the order quantity be in order to minimize the average annual cost? Also, show the minimal average annual cost. (b) Assume the discounts applied to the units are incremental, what should the order quantity be in order to minimize the average annual cost? Also, show the minimal average annual cost.Demand for an item is constant at 40 units a week, and the economic order quantity is calculated to be 100 units. What is the reorder level if lead time is constant at 4 weeks. What is the effect of add some margin of safety and raising the reorder level by ten units? What happens if the lead time (a) falls to 2 weeks or (b) raises to 6 weeks?
- A company has a demand for 25,750 units annually. The holding cost is 33% of the item cost which is $10.00. The ordering or set-up cost is $250.00 per order and the lead time is 5 days. Assume that there are 350 days per year Suppose a price break of $50 per order is offered for purchase quantities of 2,000 or greater. Question: What is the reorder point for this inventory strategy? What is the inventory position immediately after an order is placed for the inventory strategy that you have selected?Petromax Enterprises uses a continuous review inventorycontrol system for one of its SKUs. The following informationis available on the item. The firm operates 50 weeks in a year.Demand = 50,000 units>yearOrdering cost = $35>orderHolding cost = $2>unit>yearAverage lead time = 3 weeksStandard deviation of weekly demand = 125 unitsa. What is the economic order quantity for this item?b. If Petromax wants to provide a 90 percent cycle-servicelevel, what should be the safety stock and the reorder point?Current decision to buy: Ross White's machine shop uses 300 brackets each month during the course of a year. This usage is relatively constant throughout the year. Currently, these brackets are purchased from a supplier 100 miles away for $25 each and the lead time is 2 days. The holding cost per bracket per year is $3.75 (15% of the unit cost) and the annual ordering cost per order is $18.50. There are 240 working days per year. Possible future decision to make in-house: Ross White is reconsidering his decision of buying the brackets and is considering making the brackets in-house. He has determined the set up costs would be $22.50 in machinist time and lost production time. Forty eight brackets could be produced in a day once the machine has been set up. Ross estimates that the cost (including labor and materials) of producing one bracket would be $22.85. The holding cost would be 12% of the cost. What is the EOQ given Ross' current decision to buy the brackets? What is the…

- You have been asked by your boss to calculate the Economic Order Quantity (EOQ) for one of the major sub-components used by your firm. You have been provided the following data: The weekly demand for this part is 125 units. The cost of the sub-component is $300. The annual holding cost is 0.5% and the ordering or setup cost is $50.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)Annual demand for a product is 11,960 units; weekly demand is 230 units with a standard deviation of 50 units. The cost of placing an order is $125, and the time from ordering to receipt is four weeks. The annual inventory carrying cost is $0.80 per unit. To provide a 98 percent service probability, what must the reorder point be? Suppose the production manager is told to reduce the safety stock of this item by 125 units. If this is done, what will the new service probability be?
