Insert a new factor under the main root of the criteria tree or under a selected group of factors in the criteria tree. Factors are non-binding criteria and are considered as preferred for situations that can compensate each other.
A factor can either be a cost or a benefit.
- A factor is a
benefit when high values in the input map are considered to have a positive effect on the composite index output map.
- A factor is a
cost when high values in the input map are considered to have a negative effect on the composite index output map (e.g. slope values in degrees for selecting a waste disposal area).
The Factor dialog box appears:
- when you are in the
Problem Definition mode, and
- when you selected the
main goal, or when you selected a sub goal (i.e. a group), and
- do one of the following:
- choose Insert Factor from the Edit menu in the SMCE window,
- click the Insert Factor button
in the toolbar of the SMCE window,
- click the main goal or a group of factors with the right mouse button and choose Insert Factor from the context-sensitive menu.
- press the Insert Key on the keyboard and choose Insert Factor from the context-sensitive menu.
Dialog box options:
Name: |
Type a new textual name for this factor to describe it. |
Benefit:
|
Consider the new factor as a benefit (default). |
Cost:
|
Consider the new factor as a cost. |
Tips:
- The newly inserted factor will appear under the main goal or under the sub goal that you selected in step 2 above.
- Next, select the input map or an input attribute column which will be used to calculate with this factor.
