Loading a Previously Saved Scenario

Scenario results should contain four files that help to load a saved scenario: Available blocks, scheduled treatments, target status and target values. These four data files contain the values needed to reset various aspects of the model to the exact location it was left when a scenario was saved.

The block availability file is a record of the status of each block in the planning area for each planning period. It is important to load this file IF the block availability was changed in the scenario from the original starting conditions. If no changes were made to the availability it is unnecessary to reload this file (and it'll save you a lot of time!).

The schedule file contains a record of all the blocks with scheduled treatments, as well as the timing and type of treatment. This is the 'solution' to the scenario and will reset the scheduler to the position it was left.

The target status file is a record of which accounts were active in the scenario and whether minimum and maximum target levels and weights were active. The target status file also sets discount rates. The target summary file contains the actual values for each account and target level in each planning period. These two files reset the target charts and levels from the saved scenario.

Further changes can be made to the scenario, such as adjustments to target weights and values, manual schedule adjustments, and block availability. The Patchworks Map Viewer and Table Viewer tools can also be used to further explore the details of the scenario. If changes are made and the scenario is run again the results should be saved to a new scenario folder with a different name that indicates the modifications.

Reloading a scenario is aided by another 'Wizard' that provides instructions and an opportunity to load any of the four data files needed to reset various features in the model. Choose the Load a Saved Scenario to launch the Wizard. The first three panels of the Wizard provide instructions regarding available components and optional files. You have the opportunity to load only the components you require. For example, you may wish to use target settings from a previous run but not the allocation. In this case you would load only the target status and summary files. In another example, you may wish to use only the block availability settings but different target levels. In this case you would only load the block availability file. If you wish to load any of the four files check the check box to activate the directory browser. If you do not wish to load the file simply choose 'Next' in that window.
