MTBF (Mean Time Between Failures) is the gold standard indicator for measuring the reliability of a repairable asset. It represents the average time between one repaired failure and the next incident on the same equipment.
Simplified Formula: (Total Operating Time) / (Number of Failures)
A high MTBF is a good sign: it means the system runs correctly for a long time without interruptions. A low MTBF indicates instability and constant failures.
Why is it critical to calculate?
MTBF answers the most important financial question: Is it worth continuing to repair this or is it time to buy a new one? If an LED luminaire has a decreasing MTBF (breaking down more and more frequently), the cost of sending a crew to repair it will quickly exceed the cost of replacing it with a new one. Without this data, companies throw money at endless repairs of obsolete equipment.
Spatial analysis of MTBF with Maptainer
In urban maintenance, failure is not always the equipment's fault; sometimes it's the environment's fault. Maptainer allows you to visualize MTBF on the map. This reveals hidden patterns that a spreadsheet cannot show.
Example: If you see a very low MTBF on all streetlights on a specific street, the problem isn't the bulbs, but probably a voltage surge on the line or a structural problem in that area. Maptainer helps you diagnose the root cause by analyzing the geographic distribution of failures.
