CModel Class

Represents a model resource.

Constructors

Name	Description
cModel	Creates an instance of the cModel class.
cModel()	A parameterized constructor for the cModel class. (.NET only)

Name	Description
SetModel	Sets the model type, category, name and parameters of an associated cModel object.
Parameters	Returns an array of ParamValues objects that represent the parameter name and value pairs of an associated cModel object.

ALTA Models

Name	Description
ScaleParameter_A	For ALTA models, returns the scale parameter at the use stress level. Double. Returns 0 if the model is not an ALTA model.
SetUseStress	Updates the use stress value for the stress with the specified index.

Standard Calculations

Name	Description
Reliability	Returns the reliability at the specified time. Double
Unreliability	Returns the probability of failure at the specified time. Double
Time	Returns the time at which a specified reliability will be achieved. Double
MeanTime	Returns the mean time to failure. Double
Pdf	Returns the y-value of the pdf at the specified x-value (time). Double
FailureRate	Returns the failure rate at the specified time. Double

Confidence Bound Calculations

Name	Description
SetConfidenceLevel	Sets the confidence level to use in confidence bounds calculations for published models. Returns a Boolean value; when true, indicates that a confidence level has been set.
Bounds_Reliability	Calculates the bounds on the reliability at the specified time for an associated cModel object. Returns a BoundsValues object that represents the confidence bounds.
Bounds_Unreliability	Calculates the bounds on the probability of failure at a specified time for an associated cModel object. Returns a BoundsValues object that represents the confidence bounds.
Bounds_Time	Calculates the bounds on the time at which a specified reliability will be achieved for an associated cModel object. Returns a BoundsValues object that represents the confidence bounds.
Bounds_MeanTime	Calculates the bounds on the mean time to failure for an associated cModel object. Returns a BoundsValues object that represents the confidence bounds.
Bounds_FailureRate	Calculates the bounds on the failure rate at a specified time for an associated cModel object. Returns a BoundsValues object that represents the confidence bounds.
Bounds_Parameters	Calculates the confidence bounds on the parameter estimates of an associated cModel object. Returns a ParamBoundsValues object that represents the confidence bounds on the parameter estimates.

Name	Description

Name	Gets or sets the name of the model. String
Type	Gets or sets a value from the ModelTypeEnum enumeration, which specifies the types of models (e.g., 2-parameter Weibull).
Designation	Gets a string representing the model type (e.g., 2P-Weibull). String
Category	Gets or sets a value from the ModelCategoryEnum enumeration, which specifies the model categories (e.g., reliability).
ProjectID	Gets the numerical ID of the project the model belongs to. Integer
UnitID	Gets or sets the model's unit ID number. Integer
ID	Gets a string representing the numerical ID of the model. String
ConfLevel	Gets the confidence level that is currently used for calculations. Double
NumStresses	Applies to ALTA models only. Gets the number of stresses in the model. Integer
ErrorHappened	Indicates whether the last calculation produced an error. Boolean

Synthesis Identifiers
