The model class allows you to represent probabilities, durations or costs, either fixed or time-dependent. It also contains methods for accessing the calculations performed with the Quick Calculation Pad (QCP).

Properties

  • Name (as string) Gets or sets the name of the model.
  • ID (as string) Gets the numerical ID of the model.
  • ProjectID (as integer) Gets the numerical ID of the project the model belongs to.
  • Type (as ModelTypeEnum) Gets the model type (e.g., 2-parameter Weibull).
  • Category (as ModelCategoryEnum) Gets the model category (e.g., reliability).
  • Designation (as string) Gets a string representing the model type (for example "2P-Weibull").
  • ErrorHappened (as boolean) Whether or not the last calculation produced an error.
  • ConfLevel (as double) Gets the confidence level that is currently used for calculations.
  • NumStresses (as integer) Gets the number of stresses in the model.

Usage Example

Declare the WeibullDataSet. See New WeibullDataSet for additional details.

       Dim WDS as New WeibullDataSet

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

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

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

       WDS.CalculateBestFit

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

       Dim WDSFittedModel as cModel
       WDSFittedModel = WDS.FittedModel
