Selecting controls to optimize
After you define the controls in your simulation model, you can select which controls to
optimize in OptQuest. OptQuest will change the values of these controls with each
simulation until it finds values that yield the best objective. For some analyses, you might
fix the values of certain controls and optimize the rest.
Controls Editor
The Controls Editor displays the grid containing the variables or resources in your Arena
model and lets you select which controls to optimize. To access this window, either:
„
Select View > Controls
„
Click on the Controls node
The columns in this grid are:
Included Clicking on the box in the Included column will place a check that
indicates whether OptQuest will optimize the control. To change this
field, you can click on the box to remove the check mark. Without a
check, the control is not selected and OptQuest will not optimize the
control. This field is selected on the Summary window.
Category Identifies whether the control node is a resource or is a user-specified
variable. This field is for display only.
Control Displays the control name defined in Arena. This field is for display
only.
Element Type Is whether the control is a variable or resource. This field is for display
only.
Type Is whether the control is continuous, discrete, binary, or integer. This
field is changed in the edit window.
Low Bound Is the lower limit for the control. The default is 10% less than the control
value specified in the Arena model. This field is changed in the edit
window.
Suggested Value Is the initial value OptQuest uses to start the optimization process.
High Bound Is the upper limit for the control. The default is 10% more than the
control value specified in the Arena model. This field is changed in the
edit window.
Step Reflects the discrete step size. This field is changed in the edit window.
Description Allows you to enter a description of the control. This field is changed in
the edit window.
