Calculation Data for IEC TR 62380 or RDF 2000 Model
The following form is shown in the Calculation Data pane when the IEC TR 62380 or RDF 2000 model is selected for Calculation model for the top-most assembly. You cannot mix either of these models with any other model because it calculates failure rates differently. The IEC TR 62380 and RDF 2000 models use cycling profiles (operating phases) instead of mission time as the basis of their calculations. If you change the model for the top-most assembly from some other model to the IEC TR 62380 or RDF 2000 model, any other models that are specified for lower-level assemblies are ignored.
The following table describes the data fields in the Calculation Data Data pane for the IEC TR 62380 or RDF 2000 model. Field availability depends on selections made in various fields.
Field | Description |
Name | The name assigned to the assembly in the System Tree Items table. |
Calculation model | The reliability prediction standard or model to use to compute the predicted failure rate of the assembly. Choices include all licensed models. As described in Model Selection, a lower-level assembly inherits the model selected for its parent assembly. The IEC TR 62380 or RDF 2000 model can be selected only for the top-most assembly (system). When one of these models is selected, you cannot specify an override model for a lower-level assembly. |
Cycling profile | The profile (operating phase) that the IEC TR 62380 or RDF 2000 is to use in its calculations. The first profile in the Cycling Profiles file is selected by default. If the default Prediction Cycling Profiles file is enabled, the default profile is Continuous Operation. The time at which the IEC TR 62380 or RDF 2000 model is to calculate reliability is specified by Calculate reliability at in the System file properties. Under Prediction, this property is set to 100 by default. For more information, see Prediction System File Properties. |
 | The subsequent fields specify whether assembly results are calculated or specified. For more information, see Calculation Data for Specifying Whether Assembly Results are Calculated or Specified. |
