Double-click the Optimization component icon . The Optimization Component Editor appears.
From the Optimization Component Editor,
click the General tab.
Click Advanced Options.
Click the Execution tab, and
set the following options:
Option |
Description |
Execute subflow only once |
Click
this option to execute the subflow only one time and to calculate the
constraints, objectives, and penalty values. This is useful in models
that need to turn the driver logic on/off parametrically. This option
is also helpful in the debugging process if the model does not execute
successfully. You can map this setting to a parameter. For more information,
see Mapping Options and Attributes to Parameters. |
Allow the following items to be turned off
by parameters |
Click this option to disable some design parameters
at run time by using parameters. When this option is selected, a set
of special “switch” variables are created. By changing the values
of these special variables, you can disable their corresponding design
parameters. You can select Design Variables, Constraints, or Objectives. |
Import configuration at runtime |
Click this option if you want to import the Optimization component configuration
from a file at run time. If selected, Isight
creates an input file parameter on the Optimization component called
Configuration. You can point the Configuration
file to a specific file or map it from a file parameter from a previous
component in the simulation process flow. Click the button to configure
the file parameter to point to the desired file. You can also configure
this file on the Design Gateway
Files tab. For information about importing/exporting
and the file format, see About Importing and Exporting Configuration Files. |
Click the General Termination
tab.
Select any of the following termination criteria.
If you select more than one criterion, optimization
terminates whenever any of the criteria are met.
Option |
Description |
The latest design point is |
Select feasible or infeasible.
Optimization terminates when the design point becomes feasible or infeasible. |
The number of subflow runs reaches |
Enter the number of subflows that you want to complete before optimization
terminates. |
The elapsed execution time for this component
reaches |
Enter the amount of time that you want to elapse
before optimization terminates. Time can be entered in seconds, minutes,
or hours. |
The date and time reaches |
Enter
the date and time when you want optimization to terminate. Enter the
date and time in the following format: 6/12/09 02:20 PM |
Click the Parameter Termination
tab.
-
Click Terminate optimization when the
following parameter criteria are satisfied, and set the following options:
- Criteria must be satisfied over the following
number of consecutive subflow runs. Enter the number of subflow
runs that must satisfy the selected termination criteria before optimization
terminates.
- Criteria will be tested after the following
number of initial subflow runs. Enter the number of subflow
runs that you want to complete before the criteria are tested.
- Terminate optimization only when ALL selected
criteria are satisfied. Click this option if you want all
the selected parameter criteria to be met before optimization terminates.
If this option is not selected, the optimization terminates when any
one of the parameter criteria is met.
- In the first column, click the check boxes next to
the parameters that you want to use as termination criteria. Alternatively,
you can click Check to add all the selected parameters.
To clear all the parameters, click Uncheck and click Terminate
optimization when the following parameter criteria are satisfied.
- Enter the upper and/or lower threshold that, when crossed,
terminate this optimization.
Click OK to save your changes
and to close the Advanced Options dialog box.
