**Member of**: SynthesisAPI9.cModel

A parameterized constructor for the cModel class. (VB.NET only)

## Syntax

cModel(ModelType,ModelCategory,ModelName, ParamArrayModelParams())

### Parameters

*ModelType*

- Required. The type of model (e.g., 2-parameter Weibull). Can be any of the model types listed in the table below. These constants are obtained from the ModelTypeEnum.

*ModelCategory*

- Required. The model category (e.g., reliability model). Can be any ModelCategoryEnum constant.

*ModelName*

- Required. String. The model name.

*ModelParams()*

- Required. Double. An array of the model's parameters.

Model Type | Order of Parameters |
---|---|

Weibull | 1 = Beta, 2 = Eta, 3 = Gamma |

Normal | 1 = Mean, 2 = Std |

Lognormal | 1 = LogMean, 2 = LogStd |

Exponential | 1 = Lambda, 2 = Gamma |

G-Gamma | 1 = Mu, 2 = K |

Gamma | 1 = Mu, 2 = K |

Logistic | 1 = Mu, 2 = Sigma |

LogLogistic | 1 = Mu, 2 = Sigma |

Gumbel | 1 = Mu, 2 = Sigma |

Mixed Weibull | 1 = Subpop1-Beta, 2 = Subpop1-Eta, 3 = Subpop1-Portion, 4 = Subpop2-Beta, 5 = Subpop2-Eta, 6 = Subpop2-Portion, 7= Subpop3-Beta, 8 = Subpop3-Eta, 9 = Subpop3-Portion, 10 = Subpop4-Beta, 11 = Subpop4-Eta, 12 = Subpop4-Portion |

FixedUnreliability | If creating a constant model, enter a value for Parameter 1 and set Parameter 2 to zero (0) or nothing. If creating a dynamic model, enter the numeric ID of the variable resource for Parameter 2 and set Parameter 1 to zero (0) or nothing. If the variable does not exist, it creates a dynamic model with no predefined variable. |

## Example

VB.NET'The following code creates a 2-parameter Weibull reliability model, 'with beta 1 and eta 100. The model name is "MyNewModel." Dim ModelParams(1) As Double ModelParams(0) = 1 ModelParams(1) = 100 Dim newModel As New cModel(ModelTypeEnum.Weibull2,ModelCategoryEnum.Reliability, "MyNewModel", ModelParams) 'Alternatively, you can create a new model using an in-line parameter list. Dim newModel As New cModel(ModelTypeEnum.Weibull2, ModelCategoryEnum.Reliability, "MyNewModel", 1, 100)
