It is decided that enlarging P-1 is the optimum solution, so new scenarios are created to check the results for average day and maximum day demands. Notice that this step does not require handling any new data. All of the information we want to model is present in the alternatives we already have!

Also note that it would be equally effective in this case to inherit the Avg. Day, Big P-1 scenario from Avg. Day (changing the physical alternative) or to inherit from Peak, Big P-1 (changing the demand alternative). Likewise, Max. Day, Big P-1 could inherit from either Max. Day or Peak, Big P-1.

Neither the demand nor physical alternative hierarchies were changed in order to run the last set of scenarios, so they remain as they were.
