Reliability-centered maintenance RCM is a process to ensure that systems continue to do what their user require johnn their present operating context. Successful implementation of RCM will lead to increase in cost effectiveness, reliability, machine uptime, and a greater understanding of the level of risk that the organization is managing.

It is generally used to achieve improvements in fields such as the establishment of safe minimum levels of maintenance, changes to operating procedures and strategies and the establishment of capital maintenance regimes and plans.

Successful implementation of RCM will lead to increase in cost effectiveness, machine uptime, and a greater understanding of the level of risk that the organization is managing. The late John Moubray, in his book RCM2 characterized reliability-centered maintenance as a process to establish the safe minimum levels of maintenance. This description echoed statements in the Nowlan and Heap report from United Airlines. This starts with the seven questions below, worked through in the order that they are listed:.

Reliability centered maintenance is an engineering framework that enables the definition of a complete maintenance regimen.

It regards maintenance as the means to maintain the functions a user may require of machinery in a defined operating context. As a discipline it enables machinery stakeholders to monitor, assess, predict and generally understand the working of their physical assets. The second part of the analysis is to apply the “RCM logic”, which helps determine the appropriate maintenance tasks for the identified moubrsy modes in the FMECA.

Once the logic is complete for all elements in the FMECA, the resulting list of maintenance is “packaged”, so that the periodicities of the tasks are rationalised to be called up in work packages; it is important not to destroy the applicability of maintenance in this phase.

Lastly, RCM is kept live throughout the “in-service” life of machinery, where the effectiveness of the maintenance is kept under constant review and adjusted in light of moubry experience gained. RCM can be moubrayy to mouray a cost-effective maintenance strategy to address dominant causes of equipment failure. It is a systematic approach to defining a routine maintenance program composed of cost-effective tasks that preserve important functions.

The important functions of a piece of equipment to preserve with routine maintenance are identified, their dominant failure modes and causes determined and the consequences of failure ascertained. Levels of criticality are assigned to the consequences of failure. Some functions are not critical and are left to “run to failure” while other functions must be preserved at all cost. Maintenance tasks are selected that address the dominant failure causes.

This process directly addresses maintenance preventable failures. Failures caused by unlikely events, non-predictable acts of nature, etc. When the risk of such failures is very high, RCM encourages and sometimes mandates the user to consider changing something which will reduce the risk to a tolerable level.

The result is a maintenance program moubrqy focuses scarce economic resources on those items that would cause the most disruption if they were to fail. RCM emphasizes the use of predictive maintenance PdM techniques in addition to traditional preventive measures.

The term “reliability-centered maintenance” was first used in public papers [2] authored by Tom MattesonStanley NowlanHoward Heapand other senior executives and engineers at United Airlines UAL to describe a process used to determine the optimum maintenance requirements for aircraft.

Having left United Airlines to pursue a consulting career a few months before the publication of the final Nowlan-Heap report, Matteson received no authorial credit for the work.

However, his contributions were substantial and perhaps indispensable to the document as a whole. They brought RCM concepts to the attention of a wider audience. The first generation of jet aircraft had a crash rate that would be considered highly alarming today, and both the Federal Aviation Administration FAA and the airlines’ senior management felt strong pressure to improve matters. In the early s, with FAA approval the airlines began to conduct a series of intensive engineering studies on in-service aircraft.

The studies proved that the fundamental assumption of design engineers and maintenance planners—that every airplane and every major component in the airplane such as its engines had a specific “lifetime” of reliable service, after which it had to be replaced or overhauled in order to prevent failures—was wrong in nearly every specific example in a complex modern jet airliner.

This was one of many astounding discoveries that have revolutionized the managerial discipline of physical asset management and have been at the base of many developments since this seminal work was published. Among some of the paradigm shifts inspired by RCM were:. This sets out the minimum criteria for what is, and for what is not, able to be defined as RCM.

The standard is a watershed event in the ongoing evolution of the discipline of physical asset management. Prior to the development of the standard many processes were labeled as RCM even though they were not true to the intentions and the principles in the original report that defined the term publicly.

Today companies can use this standard to ensure that the processes, services and software they purchase and implement conforms with what is defined as RCM, ensuring the best possibility of achieving the many benefits attributable to rigorous application of RCM.

Modern RCM gives threats to the environment a separate classification, though most forms manage them in the same way as threats to safety. RCM also offers specific criteria to use when selecting a risk management strategy for a system that presents a specific risk when it fails. Some are technical in nature can the proposed task detect the condition it needs to detect?

Others are goal-oriented is it reasonably likely that the proposed task-and-task-frequency will reduce the risk to a tolerable level? The criteria are often presented in the form of a decision-logic diagram, though this is not intrinsic to the nature of the process. After being created by the commercial aviation industry, RCM was adopted by the U. Starting in the late s, an independent initiative led by John Moubray corrected some early flaws in the process, and adapted it for use in the wider industry.

John was also responsible for popularizing the method and for introducing it to much of the industrial community outside of the Aviation industry. In the two decades since RCM2 was first released, industry has undergone massive change. Increased economic pressures and competition, tied with advances in lean thinking and efficiency methods meant that companies often struggled to find the people required to carry out an RCM initiative.

At this point in time many methods sprung up that took an approach of reducing the rigour of the RCM approach.

The result was the propagation of many methods that called themselves RCM, yet had little in common with the original concepts. In some cases these were misleading and inefficient, while in other cases they were even dangerous. Since each initiative is sponsored by one or more consulting firms eager to help clients use it, there is still considerable disagreement about their relative dangers or merits.

Also there is a tendency for consulting firms to promote a software package as an alternative methodology in place of the knowledge required to perform analyses. Although a voluntary standard, it provides a reference for companies looking to implement RCM to ensure they are getting a process, software package or service that is in line with the original report.
