ModelRisk incorporates the World’s most popular stochastic optimization engine called OptQuest by OptTek Systems, Inc. The Optimization Settings is accessed by clicking on the OptQuest icon:
which opens the Optimization Settings interface.
The optimization variables that can be inserted into the model are ordered into different categories by tabs: targets, decision variables, constraints and requirements.
The Options tab provides a number of controls for how the Optimizer will run.
Clicking the arrow on the OptQuest icon shows two more controls:
The three controls follow the natural order of an Optimization exercise: set up the model; run the optimizer; and review the results.
Clicking ‘Run optimization’ will begin an optimization run. If an optimization run has already been performed on the current model, you will be prompted whether you wish to continue with the previous run, or start afresh.
Clicking ‘Optimization Results’ will open the Optimization Results window.
