Residual By Year

The Residual By Year constraint is used to restrict the volume left at the end of a particular period to that of another period. This constraint is particularly useful for constraining the volume left in the last period.

 

The residual by year constraint window is shown below.

 

 

 

Croptype Range

Depending on what is selected in the Category field, a range of croptypes or attribute names will be available in the Croptype Range list. Using the mouse, highlight the desired croptype ranges for which the current specification is to apply. To select consecutive items in the list, click the first item, press and hold down the [SHIFT] key and click the last item. To select non-consecutive items, press and hold [CTRL] and click each item.

 

First Period

It is the volume left at the end of this period that is used to constrain the last periods volume remaining.

 

=,>,<

States whether the constraint  is equal to "=", less than "<" or greater than ">" a specified value.

 

Last Period

This is the period where the remaining volume is constrained.

 

Error Checks*

The latest version of LOG now includes error checks on all inputs. This means that all fields need to have appropriate entries before the addition to the model is added. If there is something missing, or something in the wrong form, then a message is shown that prompts the user to remedy the situation.
