Understanding reliability rankings

Create reliability rankings for equipment to determine the criticality or risk a piece of equipment poses to your operation. If the machine fails, could it have safety or environmental implications, or will it result in production shutdown? Reliability rankings will help formalize the process to determine this risk based on your answers to the reliability questions you have configured.

Reliability rankings allow users to assign a Reliability Ranking Index (RRI) and Reliability Ranking Score to assess equipment risk. Users must first define criteria by which to assess the reliability risk.

Use the Decision Tree and develop the formula to calculate the Reliability Ranking Score, and use the assigned score ranges to determine which RRI should be applied.

To utilize the reliability ranking functionality, perform the following tasks:

1. Create a reliability ranking record.
2. Add levels to the decision tree structure.
3. Add answers to the decision tree.
4. Add formulas to the decision tree.
5. Add normalization values to the decision tree.
6. Order questions for the decision tree.
7. Assign ranking scores to reliability ranking index values.
8. Associate equipment to a reliability ranking.
9. Answer the reliability survey.
10. Calculate reliability ranking values.
