Reliability-Centered Maintenance

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:

  • Efficiency
  • 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.
