The MIL 217 module was created using MIL-HDBK-217, a US Department of Defense standard for the reliability prediction of electronic components.

What's in MIL-HDBK-217?

MIL-HDBK-217 provides two reliability prediction methods:

  • The Parts Count Method. This is a simpler approach for use during the early design phase and requires less information to be entered, for example quality, quantity and environment.
  • The Part Stress Method. This is more complex and requires detailed information on temperature conditions and electrical stress. The part stress method is used when the actual hardware and circuits are being designed.

The Reliability Workbench Prediction Module supports both of these methods to enable you to choose the level of detail you need.

How do I build a MIL-217 Model?

To build a MIL-217 model you define your systems, sub-systems and components in the Prediction tree. Following this, you add accurate data to each component in your system or sub-system. RWB Prediction will then calculate your failure rates automatically.
