To Conduct a Multi-Objective Design StudyTo conduct a multi-objective design study, you must define the design variables and the design goals.You can select dimensions or top-level model parameters (except integer parameters) as the designvariables. For the design goals, you can select parameters that were created through the Analysisfeature.

1.Click Analysis Multi-Objective Design Study . The Multi-Objective Design Study dialog box opens. The dialog box consists of two sections:

Table Tree The first column displays the hierarchy of tables in the study, including the master tableand derived tables. The second column is a feedback section, displaying the number of records for each table.

Table Data Displays the Name and the number of Records for the currently active table at the topand the table contents below. Each row in the table represents a record of an experiment. Eachrecord in the table includes a record number, values for the design goals, and design variables inindividual columns. The names of the design goals and design variables are used as the columnlabels. You can resize the columns by dragging or double-clicking the column separators.

2. To create a new study, click File New and specify a name for the study. To open an existing

study, click File Open and select the name of the study.3. To set up a master table, click Setup Variables/Goals . The Master Table dialog box opens.4. In the Sampling Method drop-down, select Automatic or Manual as the method of sampling.

5. If you select the Automatic method, specify the following in the Master Table dialog box: Click the Define Increments check box to set increments for the design variables. The Incremen

column appears in the Design Variables section of the Master Table dialog box. Specify the increment value for each of the design variables or accept the default increment

value. The default increment value is the difference between the maximum and minimumvalues of that design variable.

Design Variables For each design variable, click to add a dimension or to add a

parameter as a design variable in the study. The dimension or parameter that you add isincluded as a design variable in the study. Each design variable is assigned to a unique row of the Design Variables table. Specify its minimum and maximum values or accept the defaultvalues. You can also specify an increment for the variable if you have clicked the DefineIncrements check box. To delete a variable from the list of design variables, select the variable

and click . Design Goals Click Select Goals . The Parameter Selection dialog box opens. Select the

parameters that you want to include in your study and click OK .

6. If you select the Manual method,specify the following in the

Master Table dialog box:

Specify the design variables and design sampling.NoteEach design variable is assigned to a diff

7. Click OK to accept the setup.8. To review the setup, click Setup Show setup .9. To compute the master table, click Setup Compute and type the number of experiments you

want Pro/ENGINEER to generate, to conduct the study. The Multi-Objective Design Study dialog box displays the results. The Table Tree section displays the Master Table . The record number,computed values of the design goals, and the corresponding values of the design variables appear in individual columns in the Table Data section for the Master Table .NoteIf you have selected the Define Increments box for the Automatic method of sampling or, if youhave selected the Manual method of sampling, then Pro/ENGINEER calculates the number of experiments and displays it in the message area.

10. To create a derived table, click Table Derive . The Derive Table (MASTER_TABLE) dialog boxopens.NoteYou cannot expand a master table that uses increments for its design variables or that has beencreated using the Manual method of sampling.

11. Select one of the followingmethods for deriving a table: Constraints Creates a derived table by

design goals. Select a parameter in the pMax boxes or accept the default values.

Pareto Creates a derived table by optimOptions and set its value to Maximize

12. Type the table name and click OK . The Multi-Objective Design Study dialog box displays theresults. The Table Tree section displays the derived table icon . The record number, computed

values of the design goals, and the corresponding values of the design variables appear inindividual columns in the Table Data section for the derived table.NoteThe number of experiments used for generating the records for the derived table is derived fromthe master table.

13. To create another derived table, click a table in the Table Tree section, click Table Derive , andcreate a table from the parent derived table by selecting the Constraints or the Pareto method.Each derived table appears in the Table Tree section with an icon indicating its method of creation.

14. To save the study including the derived tables, click File Save in the Multi-Objective DesignStudy dialog box.

15. Click File Exit to end the study.Related LinksAbout the Multi-Objective Design StudyAbout the Terminology Used in the Multi-Objective Design StudyTable OperationsTo Expand the Master TableTo Set the Display of Columns
