MTBF, MTTR & Equipment Availability Simulator
Calculate Mean Time Between Failures, active Mean Time To Repair, and Inherent vs. Operational Availability adhering to ISO 14224 world-class reliability standards.
Configure Parameters to Run Model
Mean Time Between Failures
Mean Time To Repair
Includes planned PM and unplanned outages
Reflects pure equipment hardware reliability
Near industry average (95.0% - 98.4%). Targeted predictive monitoring will eliminate repeat downtime.
Rigorous Engineering Formulations
Mean Time Between Failures (MTBF)
Measures the operational duration a machine runs before encountering an unscheduled breakdown. A higher MTBF reflects superior mechanical health and lubrication hygiene.
Mean Time To Repair (MTTR)
Measures maintainability: the average active clock hours required for technicians to isolate, replace, align, and recommission the failed component.
Operational Availability (Ao)
Reflects true bottom-line production uptime, penalizing both unplanned breakdowns and inefficient preventive maintenance outages.
Comparative Performance Quartiles
| Benchmark Quartile | Target Metric Range | Operational & Financial Implication |
|---|---|---|
| World-Class | > 98.5% | Exceeds global petrochemical benchmark. Unplanned failure rate < 0.05/yr. |
| Satisfactory | 95.0% - 98.4% | Standard industry average. Repeat minor outages require targeted condition monitoring. |
| Critical | < 95.0% | High operational vulnerability. Chronic downtime severely degrades production margins. |
Actionable Engineering Best Practices
Deploy Continuous Edge Telemetry
Catch micro-impacts months before functional failure to schedule repairs during planned turnaround windows, driving MTBF upward.
Standardize MRO Staging Work Packs
Pre-stage replacement seals and specialized alignment tooling in the storeroom to shrink MTTR by 40%.
Stream Live Sensor Telemetry Directly into CMMS Metrics
Eliminate manual spreadsheet logging. Optruss connects directly to PLC/SCADA tags and vibration sensors to compute live MTBF, calculate real-time downtime loss, and dispatch predictive work orders before machines trip.
