Configuring the Optimal Latin Hypercube Technique

You can configure the Optimal Latin Hypercube options.

  1. Double-click the Six Sigma component icon .

    The Six Sigma Component Editor appears.

  2. From the General tab's Analysis Type list select Design of Experiments, and from the Technique list select Optimal Latin Hypercube.

  3. Enter the Number of Points that you want to study. For each defined factor, the levels are defined by uniformly distributing this number of points between the specified lower and upper values. These levels are randomly combined with other factor levels to define each design point to execute.

    You can map this option to a parameter.

  4. Enter the Maximum Time to Optimize (minutes) that the component can optimize. Once this time limit is reached, the optimization stops.

    You can map this option to a parameter.

  5. Click Use a fixed seed Select this option to manually specify the seed in teh corresponding text box. Type the value of the random seed in the corresponding text box. If this option is not selected, Isight determines the seed randomly.

    Note: A fixed seed can also be set and used for the entire model. If a fixed seed is set for the model and also defined separately in the Six Sigma component, Isight uses the one defined in the Six Sigma component. If a fixed seed is set for the model and this option is not selected, the sequence of random numbers is based on the model’s random seed (and, thus, is still reproducible).

    For information about setting a fixed seed, see Setting the Execution Options in the Isight User’s Guide.

  6. Click OK to save your changes and to close the Six Sigma Component Editor.
