- The chapter presented various approaches for the control of inventory investment. Discuss three additional approaches not included that might involve supply chain managers.Alina 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. Using the economic order quantity model What is Alina Ltd’s optimum order quantity? If the supplier guarantees a three (3) day delivery on any order that is placed, What is the re-order point?Daily demand for a product is 120 units, with a standard deviation of 30 units.

- Dunstreet’s Department Store would like to develop an inventory ordering policy of a 95 percent probability of not stocking out. To illustrate your recommended procedure, use as an example the ordering policy for white percale sheets. Demand for white percale sheets is 5,000 per year. The store is open 365 days per year. Every two weeks (14 days) inventory is counted and a new order is placed. It takes 10 days for the sheets to be delivered. Standard deviation of demand for the sheets is five per day. There are currently 150 sheets on hand.

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?A particular branch of ABC Co. is experiencing some inventory control problems. The manager currently orders 5,000 units four times each year to handle annual demand of 20,000 units. Each order costs P15 and each unit costs P1.50 to carry. The branch maintains a safety stock of 200 units. IF proper management is applied, how much will be the inventory cost savings on the particular branch?
