Maintainability

Using the Prediction module in Reliability Workbench you can calculate aspects of the Maintainability of your system.

Defining Maintenance and Predicting Mean Time to Repair

The prediction module also allows users to define maintenance tasks and assign these tasks to replaceable items in the prediction hierarchy. The program predicts Mean Time to Repair values for sub-system and system levels in support of standards such as MIL-HDBK-472. Tasks are categorized into the following elements :

  • Preparation
  • Fault Isolation
  • Disassembly
  • Interchange
  • Reassembly
  • Alignment
  • Checkout
  • Start Up

The screen shot below shows a MIL-217 project with maintenance tasks. The task library is shown in the right hand pane:
