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).

To access/edit repository level information, including accessing/adding resources, please see Repository Class.

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.
  • UnitID (as integer) Version 10 Only- Sets or returns the unit ID.

Usage Example

 'Declare a new WeibullDataSet object. See WeibullDataSet. 
Dim WDS as New WeibullDataSet

 'Add failure times to the data set. See AddFailure. 
WDS.AddFailure(10, 1)
WDS.AddFailure(20, 1)
WDS.AddFailure(30, 1)

 'Calculate the fitted model using default settings. See Calculate.  
WDS.Calculate()

 'Assign the fitted model to a variable. 
Dim WDSFittedModel as cModel
WDSFittedModel = WDS.FittedModel

 'Calculate the reliability at time = 50 and save the result. See Reliability. 
Dim Rel as Double
Rel = WDSFittedModel.Reliability(50)
