Configuring a Custom Strategy

You can configure your Custom Strategy to run in either Sequence or a Script strategy mode.

Creating a Custom strategy involves adding design plans for eventual use in the strategy and specifying which of these design plans will actually be used during execution. You can add as many design plans as you want but use only a few for your model’s execution. The unused design plans are saved and can be used at a later time. You can also add Jython or DynamicJava scripts to your Custom strategy. For more information, see About the Custom Strategy.

Your strategy may find it useful to evaluate isolated design points and to perform explorations. Therefore, the Available Design Plans always ends with an entry named Single Run. The Single Run represents a pseudo-technique that evaluates the current design point. This allows both design plans and single executions to be added to your strategy in a uniform matter. You cannot edit the Single Run.

  1. Double-click the Exploration component icon .
    The Exploration Component Editor appears.
  2. From the Exploration Component Editor, select Customer Strategy.
  3. From the Customer Strategy Mode, select one of the following:
    OptionDescription
    Sequence Select this option to select a set of design plans to run in sequence.
    Script Select this option to select a set of design plans and to drive the design plan with a script.
  4. Click the type of design plan that you want to add to the strategy (DOE, Monte Carlo, Optimization, SDI, or Six Sigma).

    Isight adds the design plan to the Available Design Plans list with a default name. In its current state (in the Available Design Plans list) the design plan is not included in the strategy. However, it is saved by Isight and can be configured.

  5. Select a design plan, and click to configure it.

    Tip: You can also double-click any design plan to access its editor. Alternatively, you can right-click the design plan in the list to open a menu to access the editor.

    If desired, you can configure the design plan after adding it to the Custom strategy.

    The procedure for editing a design plan in a Custom strategy is identical to the procedure for editing the corresponding component. See any of the following sections for information on configuring design plans:

    Currently, you can only configure a Six Sigma design plan to perform Six Sigma Analysis.

  6. Add design plans to the simulation process flow by selecting the desired design plan, and clicking the button.

    If you are configuring a Sequence strategy, Isight adds the design plan to the Custom Strategy Step Sequence list. If you are configuring a Script strategy, Isight inserts the design plan into the script at the current text insertion point.

  7. If desired, you can remove a design plan from a Sequence strategy by selecting the design plan in the Custom Strategy Step Sequence list and clicking the button.
  8. Move the design plans added to the Custom Strategy Step Sequence list up or down using the and buttons to create the Sequence strategy simulation process flow.

    The design plans are executed in the order in which they appear in the list, with the top design plan executing first.

    Tip: You can edit or delete the design plan by right-clicking the design plan in the Available Design Plans list or the Custom Strategy Step Sequence list.

  9. If desired, you can change the name of the design plan by clicking the design plan and clicking the button.

    Important: If you are creating a Script strategy, design plan names appear as global variable names when the design plans are used in the script. Therefore, design plan names are limited to whatever strings may be used as variable names in all scripting languages. Because Python requires all identifiers, including variable names, to be in ASCII, all technique instance names must also be in ASCII.

  10. If desired, copy a design plan.

    You can create exact copies of any design plan that you have added to the Custom strategy. This is useful because you do not have to configure each design plan separately.

    1. From the Available Design Plans list, click the design plan that you want to copy.
    2. Click the button at the bottom of the list.

      Isight adds a copy of the design plan to the list.

  11. If desired, delete a design plan.

    You can delete a design plan from a Custom strategy, which makes it no longer part of the strategy. However, you can add a design plan of the same type back into the task plan and reconfigure it.

    1. From either the Available Design Plans list or the Custom Strategy Step Sequence list, select a design plan.
    2. Click .

      Isight deletes the design plan from the Custom strategy.

      Important: If you are working with a Script strategy, deleting a design plan might yield a syntactically invalid script. If you delete a design plan that was used in your script, you should inspect the adjusted script before clicking OK or Apply in the Exploration Component Editor.

  12. Click OK to save your changes and to close the Exploration Component Editor.
