WeibullDataSet Class Example

These formatted examples begin with an XML file, import it into the synthesis repository, add data, perform calculations, perform an analysis, and show results. Finally, they create a plot and display a message.

First we will show the importation of a file into BlockSim.

Declare a new repository connection class.

      Private WithEvents MyRepository As New Repository

Connect to the Synthesis repository.

      Dim Success As Boolean = False
      Success = MyRepository.ConnectToSQLRepository("SQLServerPath", "SQLDatabaseName")

Import the XML File to the Synthesis repository.

      Dim SuccessImportXML As Boolean
      SuccessImportXML = MyRepository.ImportXFRACASXMLFile("XMLFilePath")

The file has been imported. Now we will demonstrate the use of Synthesis API in Weibull.

Declare the WeibullDataSet. See New WeibullDataSet for additional details.

       Dim WDS as New WeibullDataSet

Add values to the raw data. See AddFailure for additional details.

       WDS.AddFailure(1, 1)
       WDS.AddFailure(2, 1)
       WDS.AddFailure(3, 1)

Add values to the raw data. See AddSuspension for additional details.

       WDS.AddSuspension(1, 1)
       WDS.AddSuspension(2, 1)
       WDS.AddSuspension(3, 1)

Calculate the WeibullDataSet. See Calculate for additional details.

       WDS.Calculate

Get the number of failures. In this example, NumberOfFailures will be 3. See FailureCount for additional details.

       Dim NumberOfFailures as Integer
       NumberOfFailures = WDS.FailureCount

Calculate the Fitted Model using the raw data. See CalculateBestFit for additional details.

       WDS.CalculateBestFit

Use the Fitted Model using the raw data. See FittedModel for additional details.

       Dim WDSFittedModel as cModel
       WDSFittedModel = WDS.FittedModel

Use ClearDataSet to clear data and fitted model. See ClearDataSet for additional details.

       WDS.ClearDataSet

Get the number of failures. In this example, NumberOfFailures will be 0. See FailureCount for additional details.

       Dim NumberOfFailures as Integer
       NumberOfFailures = WDS.FailureCount

The below demonstrates that plots may also be utilized.

Create a new Weibull/ALTA Plot instance.

       Dim WeibullALTAPlot As New WAPlots

Declare a WeibullDataSet. See New WeibullDataSet for additional details.

       Dim WDS As New WeibullDataSet

Add values to the raw data. See AddFailure for additional details.

       WDS.AddFailure(1, 1)
       WDS.AddFailure(2, 1)
       WDS.AddFailure(3, 1)

Add the WeibullDataSet to the WAPlots.

       WeibullALTAPlot.AddDataset(WDS)

Create the WAPlot. In this example, it will create a Probability plot.

       Dim FinalPlot As Bitmap = WeibullALTAPlot.CreatePlot(WAPlotType.Probability)

If there were any issues creating the plot, ErrorHappened would be True, and ErrorString will display the reason.

       Dim ErrorString as String
       If WeibullALTAPlot.ErrorHappened Then
           ErrorString = WeibullALTAPlot.ErrorMessage
       End If
