Bathtub Machine Reliability Analyzer

Category: Reliability

Summary

This workbook visualizes reliability using Reported Emergency Down (RED) events across a machine’s life. It calculates event frequency and intervals, then displays the classic bathtub reliability pattern to show when failures start increasing. It also plots a cumulative cost curve to reinforce reliability as a leading indicator of cost acceleration. Use it to support repair, rebuild, or replacement timing decisions and to spotlight units driving unplanned downtime.
