Reliability-centered maintenance leverages the same practices and technologies of predictive maintenance. The difference is that reliability-centered maintenance recognizes that:
- Equipment design and operations differ
- Different equipment has different probabilities of failure
- All equipment is not of equal importance to facility operations
- Facilities have limited financial and personnel resources.
While reliability-centered maintenance relies on predictive maintenance practices and technologies, it also recognizes that maintenance on inexpensive and/or unimportant equipment may be better served by a reactive or predictive maintenance approach. Each of the aforementioned factors are considered and balanced to create an optimum level of reliability and cost-effectiveness.
Advantages and Disadvantages
Reliability-centered maintenance advantages and disadvantages are identical to those of predictive maintenance because they both rely on the same practices and technologies. However, reliability-centered maintenance further benefits from closely matching facility resources to needs while improving reliability and decreasing costs.
Advantages of reliability-centered maintence are:
- Increased system reliability
- Lowered costs due to no unnecessary maintenance
- Minimized overhauls
- Reduced sudden equipment failures
- Maintenance focused on critical components
- Incorporates root cause analysis.
Disadvantages of reliability-centered maintence are:
- Significant initial costs for training and equipment
- Savings potential not readily seen by management.
