4.3.1 Capacity

First-shift capacity is defined as the number of units that can be produced on an assembly line in a single year with a daily eight-hour shift. An assembly line can produce up to twice its first-shift capacity with a second shift. An assembly line with a capacity of 2,000,000 units per year could produce 4,000,000 units with a second shift. However, second-shift labor costs are 50% higher than the first shift.

Each new unit of capacity costs $6.00 for the floor space plus $4.00 multiplied by the automation rating. The Production spreadsheet will calculate the cost and display it for you. Increases in capacity require a full year to take effect– increase it this year, use it next year.

Capacity can be sold at the beginning of the year for $0.65 on the dollar value of the original investment. You can replace the capacity in later years, but you have to pay full price. If you sell capacity for less than its depreciated value, you lose money, which is reflected as a write-off on your income statement. If you sell capacity for more than its depreciated value, you make a gain on the sale. This will be reflected as a negative write-off on the income statement (see “6.3 Income Statement”).

The dollar value limit of capacity and automation purchases is largely determined by the maximum amount of capital that can be raised through stock and bond issues plus excess working capital (see “4.4 Finance”).
