In the LCC Variables file, you can see the list of variables that appeared in the list associated with the Variables button in the LCC - Equation Editor.
You can define an LCC variable to be any of the following types:
◦ Constant — The value is fixed
◦ Varies over Time Intervals — The value changes based on time intervals that you define, which might be monthly or yearly for example
◦ Varies over Alternatives — The value changes based on alternative system designs that you define, which might be a redesign and a new design
◦ Varies over Alternatives and Time Intervals — The value varies based on both time intervals and design alternatives
3. Select > to close the LCC Variables file.
4. In the Project Navigator, click Collapse files to hide all support files.
