cModel Class

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).

Constructors

• New cModel Creates a new model.

Properties

• Name Sets or returns the name of the model (the one used in the repository)
• ID Returns the ID of the model (the one used in the repository).
• ProjectID Returns the ID of the project the resource belongs to.
• Type Returns the type of the model.
• Category Returns the category of the model.
• Designation Returns the designation of the model (for example Weibull-2).
• ErrorHappened Whether or not the last calculation produced an error.
• ConfLevel Returns the confidence level that is currently used for calculations.
• NumStresses Returns the number of stresses in the model.

Methods

• SetModel Sets a new model.
• SetUseStress Sets use stress value for a particular stress. This value is used in subsequent calculations.
• Reliability Calculates the Reliability for a given time.
• Unreliability Calculates the Unreliability for a given time.
• Time Calculates the time value for a given Reliability.
• MeanTime Calculates the mean time value for a given Reliability.
• Pdf Calculates the PDF.
• FailureRate Returns failure rate given time.
• Parameters Returns an array containing model parameters and their values.
• ScaleParameter_A Returns the scale parameter for ALTA models. Returns 0 if the model is not an ALTA model.
• Bounds_Reliability Returns the bounds on the reliability given time.
• Bounds_Unreliability Returns the bounds on the unreliability given time
• Bounds_Time Returns the bounds on time given reliability
• Bounds_MeanTime Returns the bounds on mean time
• Bounds_FailureRate Returns bounds on failure rate given time.
• Bounds_Parameters Returns an array containing bounds on all model parameters.
• SetConfindenceLevel Sets the confidence level for all subsequent confidence bounds calculations.
