- 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?arrow_forwardAlina Limited is a manufacturer of widgets orders components for use in manufacturing. The estimated demand for the components during the coming year is 15,000. Order costs are $100 per order; carrying costs are $12 per component.

If the supplier guarantees a three (3) day delivery on any order that is placed, What is the re-order point?arrow_forwardAmong the following multi-period inventory models, which one has the highest probability of stockout?

- Demand for sandwiches is normally distributed with a mean of 1,280 and a standard deviation of 220. The order quantity is 1,485 units. What is the expected inventory (in units)?arrow_forwardA store uses an EOQ system for one of its most popular product. The product has a daily demand of 49 units. The store purchases the product from a supplier. The supplier has an order lead time of 6 days. The store uses an order quantity of 1617 units. A shipment of the supplier always at the beginning of day and the store always place a new order at the end of day. The store also monitors its inventory continuously. Assume that a shipment arrives at the beginning of day 1 and the beginning inventory becomes 1617 units. What is the inventory level at the end of day 12?arrow_forwardLittle Caesars Pizza orders all of its pepperoni, olives, anchovies, and mozzarella cheese to be shipped directly from Italy. An American distributor stops by every four weeks to take orders. Because the orders are shipped directly from Italy, they take three weeks to arrive. Little Caesars Pizza uses an average of 150 pounds of pepperoni each week, with a standard deviation of 30 pounds. Little Caesars prides itself on offering only the best quality ingredients and a high level of service, so it wants to ensure a 98 percent probability of not stocking out on pepperoni. Assume that the sales representative just walked in the door and there are currently 500 pounds of pepperoni in the walk-in cooler. How many pounds of pepperoni would you order? What is the standard deviation of demand during the review period and lead-time? How many pounds of pepperoni would you order?arrow_forward
- It takes approximately 2 weeks (14 days) for an order of steel bolts to arrive once the order has been placed. The demand for bolts is fairly constant; on the average, the manager, Michelle Wu, has observed that the hardware store sells 500 of these bolts each day.
