Introduction
In modern manufacturing, machine performance is measured not only by production speed. Metrics like MTTR (Mean Time To Repair), MTBF (Mean Time Between Failures), and OEE (Overall Equipment Effectiveness) allow you to quantify equipment reliability, availability, and overall efficiency.
Tracking these indicators is essential to reduce unplanned downtime, optimize costs, and improve productivity. With SOSMachine.net, you can quickly source replacement parts for your machines from top brands like Siemens, Schneider, Omron, Mitsubishi, ensuring fast response when issues occur.
1. MTTR – Mean Time To Repair
Definition: MTTR represents the average time required to repair equipment after a failure.
- Formula: MTTR = Total repair time / Number of repairs
- Objective: The lower the MTTR, the faster your teams repair and the fewer your downtimes are.
Example: A Mitsubishi pump breaks down. With a stock of critical parts available through SOSMachine.net, the replacement is quick, which reduces the MTTR.
Tips for reducing MTTR:
- Maintain a stock of critical spare parts by brand.
- Train technicians in rapid replacement procedures.
- Monitor recurring faults to anticipate interventions.
2. MTBF – Mean Time Between Failures
Definition: MTBF measures the average time between two failures of a piece of equipment.
- Formula: MTBF = Total operating time / Number of failures
- Objective: The higher the MTBF, the more reliable your equipment is.
Example: A Siemens S7 controller with a low MTBF can be replaced or optimised by using spare modules available on SOSMachine.net.
Tips for improving MTBF:
- Carry out regular preventive maintenance.
- Use reliable components that are brand certified.
- Implement conditional monitoring (sensors, alerts).
3. OEE – Overall Equipment Effectiveness
Definition: OEE measures the overall effectiveness of equipment, taking into account:
- Availability (actual operating time / planned time)
- Performance (actual speed / theoretical speed)
- Quality (conforming parts / total parts)
- Formula: OEE = Availability × Performance × Quality
- Objective: OEE allows you to identify losses and optimise your processes.
Example: If a Schneider inverter causes frequent stoppages, the OEE decreases. Having a stock of inverters and Schneider cards on SOSMachine.net allows for quick reactions and restoration of performance.
4. Link MTTR, MTBF and OEE to your spare parts purchases
These indicators are not only used to measure your machines, but they also help to prioritise your purchases and your stock of parts:
- Equipment with low MTBF requires spare parts to be readily available.
- Equipment with a high MTTR must have pre-assembled repair kits.
- A low OEE may indicate missing critical components or obsolete OEM parts, available on SOSMachine.net.
5. How SOSMachine.net helps you
- Large stock de marques industrielles : Siemens, Schneider, Mitsubishi, Omron…
- Fast delivery in 1 to 3 days to reduce MTTR.
- Critical and obsolete parts available to maintain or improve the MTBF.
- B2B technical support to quickly identify the suitable part.
Conclusion
Monitoring MTTR, MTBF, and OEE allows you to control the performance of your machines and optimise your industrial costs. However, these indicators are only effective if you can react quickly in the event of a breakdown.
With SOSMachine.net, find your critical industrial parts, even rare or obsolete ones, for every brand: Siemens, Schneider, Omron, Mitsubishi… and ensure the continuity of your production.
