Her operations manager is considering a new plan, which begins in January with 200 units of inventory on hand. Stockout cost of lost sales is $65 per unit. Inventory holy cost is $20 per unit per month. Ignore any idle-time costs. Evaluate the following plan:

Keep the current workforce stable at producing 1600 units per month. In addition to the regular production, another 20% of the normal production units can be produced in overtime at an additional cost of $55 per unit. A warehouse now constrains the maximum allowable inventory on hand to 600 units or less.
