Reliability-Centered Maintenance

Tools For Reliability-Centered Maintenance

Reliability-Centered Maintenance (RCM) is a process to identify an appropriate mix of applicable and effective maintenance tasks performed at appropriate intervals to maintain equipment reliability and availability at minimum cost. It is a systematic approach to evaluate the equipment’s design and operating context in terms of possible failures, the consequences of these failures, and the recommended maintenance procedures. Often equipment is purchased with a set of OEM-recommended maintenance tactics that may or may not be optimum. RCM analysis can be performed to optimize existing asset maintenance programs or can be performed as equipment is designed to develop the appropriate maintenance program. The “living” process monitors equipment performance over time to validate that the existing maintenance preserves important equipment functions, determines opportunities to improve the maintenance program and identifies developing problems.

The tools of RCM are primarily failure mode analysis and an assessment of statistical data on past failures. The results are often dramatic reductions in maintenance cost or significant improvements in machine reliability and availability or both. While helping improve your reliability we also are training your personnel to apply these principles to other equipment. At CAS we believe in creating sustainable solutions by training your people as we help you to make substantial gains.

CAS offers both training and implementation of RCM.

Here is an article that shows a little of our early background. RCM Article. Our folks implemented the RCM at United Space Alliance, the prime NASA Shuttle contractor, before forming our own company. Since then, we have helped Ford Motor Company in their quest for near perfect reliability in their factories.

Examples of the Supporting Processes

Failure Mode & Effects Analysis: Failure Mode & Effects Analysis (FMEA) identifies potential failure modes and their impact. It also identifies mitigations that can be put in place to prevent these failures and their impacts. These mitigations can vary from prevention, to periodic maintenance, to monitoring. Which is appropriate depends on the nature and consequence of the failure.

Failure Effects Modes Analysis Determines What Can Fail and the Impact

Statistical Analysis: Statistical analysis can vary from mean time between failures to frequency of failure over time to a simple Pareto chart of frequent failure modes. The result is typically an identification of past failures and the time before these failures occur. This can act as a predictive measure to schedule maintenance that will prevent these failures or replace parts that are near failure.

Time To Failure Can Determine Part Replacement Need

Decision Analysis: Often decisions must be made relative to the cost of replacement or downtime vs the cost or impact of maintenance. CAS professionals have developed the tools and logic to make the right decisions for your business and will discuss and partner options where they exist.

For each failure mode a decision must be made for each case in Reliability-Centered Maintenance
