 <li>Each plant can only be opened exactly once. After open, the plant remains open until the end of the simulation.</li>
 <li>Plants can be expanded at any time, even long after they are open.</li>
-<li>Variable and fixed operating costs do not change according to plant size.</li>
 <li>All material available at the beginning of a time period must be entirely processed by the end of that time period. It is not possible to store unprocessed materials from one time period to the next.</li>
+<li>Up to two plant sizes are currently supported. Variable operating costs must be the same for all plant sizes.</li>
