SimuMatic Folio

The SimuMatic folio gives you access to the data sets generated by the SimuMatic utility and to the results of analyses on those data sets. This topic includes information on various elements of this folio, including:

Simulation Sheet

The Simulation sheet shows the parameters calculated for each data set. It also contains a separate column for each of the calculations that you specified on the Reliabilities and Times tab of the setup window. The following example shows the results for the first ten data sets created with SimuMatic.

The sheet contains the following columns:

Note: "N/A" will appear in the parameter columns if there was an error in calculating a particular data set. This is usually an indication that there were not enough failure times in the data set to calculate the parameters.

Sorted Sheet

In the Sorted sheet, the calculated values from the Simulation sheet are sorted from least to greatest in order to show the confidence bounds. Assuming all the simulated data sets have calculated parameters, the Percentage column will display the percentage of data sets that are equal to or less than a given data set. So, for example, if you wished to obtain the 90% lower one-sided confidence bound of R(100), you would look up the value of R(100) that corresponds to 10% (i.e., 100% - 90%).

If you wished to obtain the 90% two-sided confidence bounds of R(100), you would look up the values that correspond to 5% (for the lower bound) and 95% (for the upper bound).

This concept is summarized in the figure shown below.

SimuMatic Control Panel

The SimuMatic control panel and its components are described next.

Note: Data sets without enough data points to fit to a model (i.e., those with an "N/A" in the parameter columns of the SimuMatic's data sheet) will not be shown in this report.

The following tools are available on the SimuMatic control panel:

or   SimuMatic Setup allows you to change your simulation settings and replace your current simulated data sets with new ones.

  Plot generates a probability plot of all the data sets.

  Transfer Parameters to Selected Folio is available only for Weibull++. It allows you to transfer the calculated parameter values for each simulated data set to an existing Weibull++ standard folio, with one data sheet for each parameter of the model that was used to generate the data. When you click this icon, a window will appear asking whether you want the data sheets to be configured for free-form or times-to-failure data. Then the Transfer Life Data window will appear, where you can select the existing folio that you wish to transfer the calculated parameters to.

  Transfer Parameters to New Folio is available only for Weibull++. It creates a new Weibull++ standard folio and transfers the calculated parameter values for each simulated data set to that folio, with one data sheet for each parameter of the model that was used to generate the data. After you click this icon, a window will appear asking whether you want to transfer the data to a data sheet configured for free-form or times-to-failure data. (See Weibull++ Standard Folio.)
