Manage an Optimization Set

Creating an Optimization Set

On the Optimization Set Manager, select Add Optimization Set .

Editing an Optimization Set

On the Optimization Set Manager, select an Optimization Set, and select Edit. The Optimization Set Editor appears.

Specifying the type of objective function to use for an Optimization Set

On the Optimization Set Editor, expand the Objective Function area. Select Maximize or Minimize.

Specifying the goal of the optimization for an Optimization Set

On the Optimization Set Editor, expand the Objective Function area. In the box, enter the name of the variable that represents the objective function (for example, HX1.Duty). A list of available variables appears as you are entering.

Adding a variable to an Optimization Set

On the Optimization Set Editor, expand the Variables area. Select Add Variable . A new row appears in the list of variables. In the Name column for the new row, enter the name of the variable that you want to add. A list of available variables appears as you are entering.

Alternatively, drag a variable from any open Property Inspector onto the list of variables in the Optimization Set Editor.

You can add both specified and calculated variables to an Optimization Set.

The AVEVA Process Simulation solver modifies the values of the variables in the Optimization Set to maximize or minimize the objective function. At least one variable in the Optimization Set should affect the objective function when you change the value of that variable.

Adding upper and lower bounds to variables in an Optimization Set

On the Optimization Set Editor, expand the Variables area. In the Lower Bound column, enter the minimum value to which the solver can adjust the associated variable. In the Upper Bound column, enter the maximum value to which the solver can adjust the associated variable.

You can start an Optimization Set run when the variable values are outside of the specified bounds. However, if the value of a non-independent variable is outside of its bounds, a warning badge appears for that variable.

Deleting a variable from an Optimization Set

On the Optimization Set Editor, expand the Variables area. Select the variable, and select Delete Variable .

Alternatively, select the variable and press Delete.

Running an Optimization Set

On the Optimization Set Manager, select an Optimization Set, and select Run.

Alternatively, on the Optimization Set Editor for the Optimization Set, select Run.

Or

On the Process or Fluid Flow tabs, in the Optimization group, select an Optimization Set in the list, and then select Run the selected optimization set .

Copying an Optimization Set

On the Optimization Set Manager, select an Optimization Set, and select Copy.

Deleting an Optimization Set

On the Optimization Set Manager, select an Optimization Set, and select Delete.
