Prediction FIDES Ruggedized Factor File Overview
All FIDES models use a Pi ruggedized factor in their reliability calculations. In a Prediction FIDES Ruggedized Factor file, you must answer one question set.
You can enable a Prediction FIDES Ruggedized Factor file at either the assembly or part level. For an assembly, you select the file to use in its Calculation Data pane. For a part, you select the file to use in its Prediction Data pane.
• If you select a Prediction FIDES Ruggedized Factor file for the top-most assembly, it is inherited by all lower-level assemblies and parts. You then need only to specify override selections for lower-level items.
• If a Prediction FIDES Ruggedized Factor file is not inherited or specified for an assembly, a default value of 1.7 is used as its Pi ruggedized factor.
