The amount of capacity you wish to buy or sell this year in thousands of units.
Decisions to buy capacity are entered as positive numbers. For example, 100 would order 100,000 units of capacity for delivery on December 31st of this year. The new capacity will not be available until next year.
Decisions to sell capacity are entered as negative numbers. Capacity is sold on January 1st of this year.
Tip: if you want to retire a product but still have inventory on hand that you think you can sell, keep 1 unit of capacity and sell the rest. If you sell all of the capacity, the inventory will be liquidated at 50% of its value.
