Pane 3. Assume a company receives cash from different geographic areas of $500,000 daily. The average float of the cash receipt is 4 days. Interest rate on savings is 6% per year. If the company institutes a lock-box system, it will reduce the float to two days. It will cost $80,000 to install the lock-box system and an additional monthly fee of $1,000 to operate it. Should the company install the lock-box system?
A manufacturer that produces 100 different products is considering building a new warehouse because there is no room in raw material and product warehouses. Because although some products are more than in the warehouse, some demands that come due to the fact that the ban products are not enough in the warehouse are avoided. For this reason, it plans not to miss any demand by producing and storing enough of all its products, and of course it is considering building a new and larger warehouse to store more products. What can you suggest to this company, taking into account what is described in the course, describe your proposal in maximum detail with the concepts described in the course, as applicable activities.
14. 12 The purchasing manager for the Atlantic Steel Company must determine a policy for ordering coal to operate 12 converters. Each converter requires exactly 5 tons of coal per day to operate, and the firm operates 360 days per year. The purchasing manager has determined that the ordering cost is $80 per order and the cost of holding coal is 20% of the average dollar value of inventory held. The purchasing manager has negotiated a contract to obtain the coal for $12 per ton for the coming year. a. Determine the optimal quantity of coal to receive in each order. (Ans: 1200 tons) b. Determine the total inventory-related costs associated with the optimal ordering policy (do not include the cost of the coal). (Ans: TC= $2880) c. If 5 days of lead time are required to receive an order of coal, how much coal should be on hand when an order is placed? (Ans= R=300 tons)
