You display the requirements view of a
parameter by selecting
Edit
from the
Requirements column.
The parameter formulation includes the following:
- Priority
-
Performance Trade-off
uses the priority to set the weight factor of a parameter.
You can assign a parameter a priority between
1 and
5, where
1 is the highest priority and
5 (default) is the lowest priority. You can
also assign a priority of
MH, indicating a must-have parameter. A
must-have priority has the same weight as
1; however, if the threshold is not met, the
entire alternative is penalized with a score of zero.
- Objective
-
Performance Trade-off uses the objectives to assess the feasibility and to calculate
the score and rank of the different alternatives. You can choose an
objective that tries to minimize or maximize the value of a parameter.
Alternatively, you can choose an objective that tries to target the value of
a parameter to a specified number.
Note:
You can assign an objective to only a
numerical parameter.
- Threshold values
- You can assign a parameter upper and lower threshold values. If the
value of a parameter is greater than the upper threshold or lower than the
lower threshold, the corresponding data point is still scored and ranked;
however, it is considered infeasible.
Infeasible data points are indicated with the
infeasible icon
in the data table.
Performance Trade-off
displays the range of values for a parameter after you save the analytics case
and refresh your display.
Note:
You can assign a threshold value to
only a numerical parameter.
