Data used for the various improvements in a system is often tweaked for better performance of the different elements. We know how important it is to use and allocate the best resources to the task at hand. The maintenance of equipment in an organization is one of the critical factors in delivering seamless operations. Cost is also considered when purchasing items for the maintenance procedures, meaning you must pay attention to all these factors when foraying into the different stages of such activities. Equipment reliability doesn’t come easy because the calibration of the equipment could be time-consuming. Quality benchmarks are set by the organizations to measure the effectiveness of maintenance. The equipment performance can be understood by using different metrics, which draw a line between the differences of the various goals in the same body. Maintenance metrics are, therefore, an indispensable part of the procedure. Let us look at some of the most important maintenance metrics.
1. Planned Maintenance Percentage
PPC is the type of metric that focuses on the percentage of time spent on planned maintenance activities, which should have been a part of your preventive maintenance plan. This should be considered against the unexpected breakdowns of the system. If it is an efficient body, almost 90% of the maintenance should be planned.
PPC= (scheduled maintenance time/total maintenance time) x 100
2. Overall Equipment Effectiveness
The productivity of a piece of equipment is measured in OEE, giving you informed data on the effectiveness of the various maintenance processes in an organization. Factors such as performance, quality, and availability determine the operational effectiveness of such a system. If an OEE of 100% is recorded, it means that your system is as fast as possible and has no defects. Eliminating the items having a negative impact on your production also becomes easy when this metric is used.
OEE= Availability x Quality x Performance
3. Mean Time to Repair
The measure of the repairable items’ maintainability is defined by MTTR, which has a clock that starts ticking when the system begins work on the repairs. Every organization aims to reduce the MTTR as much as possible. Huge losses will be generated if the team doesn’t pay attention to the different details to reduce the number of hours spent on restoring assets.
MTTR= (Total of the downtime periods/total number of repairs)
4. Mean Time Between Failure
In MBTF, the predicted time between one breakdown to the next in a normal operation is measured. An equipment’s expected lifetime is recorded by this metric. The higher the MTBF, the longer the product will work for the system. When you know this functional period, prediction and preparation for a failure become easier.
MBTF= (Total operational time/total number of failures)
5. Preventive Maintenance Compliance
This is the percentage of the preventive work completed in a set time. PMC gives you a precise value indicating the orders and elements covered for a selected month. However, this metric doesn’t assure the completion of an order on time.
