Nissan Motors has been producing a particular ignition box for its car engines. The Fabrication Department of the company has a monthly demand of 500 ignition boxes (Part #37822) with a weekly standard deviation of 80. The leadtime for this part is two weeks. For the purposes of this problem, you may assume that each month is exactly 4 weeks long. Nissan requires a 97% service level for this item.

In the Fabrication Department, 20 hours (with labor costs of $30 per hour) is allowed for each setup of Part #37822. The Accounting department has determined the variable cost per box of Part #37822 is $100, while the Finance Department requires a carrying cost of 25% per year of the value of any item in inventory.
