Measurement Size Configuration

You have to define the number of measurements of the experiment plan either manually or via the options in the Expected System Complexity area. The following options are available.

  • Low: For systems with approximately linear dependencies between inputs and outputs.

  • Medium: For systems whose behavior approximately corresponds to a polynomial of second or third degree (such as a local operating point of an engine, for example).

  • High: For complex systems which can no longer be represented using polynomials (such as an engine over an extended operating range, for example)

Configuring the number of measurements

  • In the Actual Number of Measurements field, enter the desired number.

    Or

    In the Expected System Complexity area, activate the option that best describes your system.

    Depending on your selection, a number is written to the Proposed Number of Measurements field.

    Note  

    The number proposed by the system depends on the number of inputs and on system complexity.

  • Activate the Use Proposal checkbox to use the suggested value.

With a large number of measurements, it is recommended that you split the measurements into smaller blocks (see Step 6: Block Configuration) and, during modeling, try out how many blocks of this size are necessary to achieve the desired model quality.

Step 1. General Settings results in a finished experiment plan that could now be exported as an *.xls or *.csv file. For more information on how to export an experiment plan, see section Step 9: Export .
