What is rcm analysis

The criticality of each of these failure modes can also be considered. There are various recommended techniques that are used to give this step a systematic approach. These include:.

The most important failure modes will be determined at the conclusion of this systematic analysis. Your answer is the most important failure modes that should be prioritized for further analysis. Importantly, the failure modes that are retained include only those that have a real probability of occurring under realistic operating conditions.

At this step, the most appropriate maintenance tactic for each failure mode is determined. The maintenance tactic that is selected must be technically and economically feasible. Condition-based maintenance is selected when it is technically and economically feasible to detect the onset of the failure mode.

Time or usage-based preventive maintenance is selected when it is technically and economically feasible to reduce the risk of failure using this method.

For failure modes that do not have satisfactory condition-based maintenance or preventive maintenance options, then a redesign of the system to eliminate or modify the failure mode should be considered.

Failure modes that were not identified as being critical in Step 6 may, at this stage, be identified as good candidates for a run-to-failure maintenance schedule. Importantly, the RCM methodology will only be useful if its maintenance recommendations are put into practice.

When that has been done, it is important that the recommendations are constantly reviewed and renewed as additional information is found. Since the end product of a well-executed RCM analysis is that an appropriate maintenance strategy will be selected for each piece of equipment, the impact is an overall improvement of reliability.

RCM aims to reduce costs, improve safety, and eliminate maintenance tasks that are not effective or appropriate for a given piece of machinery. Implementing RCM processes allows you to avoid a one-size-fits-all mindset that could waste valuable time and resources. Leverage the cloud to work together, better in the new connected age of maintenance and asset management.

What is RCM Reliability centred maintenance? Thus, RCM provides a management roadmap for prioritizing, optimizing, and assigning maintenance activities. United Airlines executives developed the process before catching the attention of the U.

Department of Defense in Today the maintenance process is practiced by hundreds of industrial and service organizations around the world. The RCM paradigm argues that the less maintenance you perform on an asset, the better.

Only perform maintenance when absolutely necessary or when the benefits outweigh the risks and costs. RCM is based on four key objectives:. Organizational leaders should outline their RCM goals by considering management availability, accessible technologies, and budgetary resources.

This somewhat time-consuming process carefully analyzes individual asset scenarios before assigning corresponding maintenance tasks. Assess each piece of equipment, organized by phase, by asking:. The final component of RCM is choosing and scheduling appropriate maintenance tasks. A computerized maintenance management system CMMS can schedule, assign, and oversee work orders.

As expected, different techniques are suitable for different asset situations. Some machinery may require proactive tasks, including preventive and predictive maintenance. Conversely, reactive maintenance may be the most financially prudent course of action for other low-importance pieces. Successfully implementing RCM benefits organizations that can afford it. The framework takes the guesswork out of maintenance prioritization and helps organizations maintain assets in a consistent, structured, and cost-effective manner.

Because RCM heavily relies on predictive maintenance PdM technologies, its program advantages and disadvantages mirror those of it. However, RCM allows facilities to match resources to equipment needs more closely while improving reliability and decreasing cost—more than any one singular PdM strategy.

The program also enabled the Center to minimize its energy consumption and reduce its environmental impact. RCM also has its drawbacks. The initial costs of implementing RCM are high. Performing RCM analysis requires teams to invest significant time, finances, and resources to get started. Doing these things typically cost less and show more benefits for organizations. In addition, there may be multiple minor steps within each of these major steps.

Next, the team defines the interfaces of the focused FMEA effort so the effects can be identified. Then the major components of the FMEA focus are defined and broken down further as needed , along with each of their failure modes, root causes, failure indicators, failure criticalities, failure probabilities and effects using both team member experiences with the FMEA focus area as well as any available failure history. Some of the more traditional FMEA efforts stop here.

However, we have seen the more effective FMEA efforts take this analysis and add to it the mitigation tasks and frequencies for each key characteristic candidates and identify the selected mitigation tasks to implement, ensuring that the selected mitigation tasks actually provide value by either detecting failure at the start of its failure mode or preventing a failure from occurring in the first place.

The key to success of this FMEA process is in its application — only applying the individual step, as well as the detail of this step, as needed for the specific FMEA effort. Probably the most common use of FMEA is for maintenance strategy development for a specific piece of equipment, product line, or facility. The preceding steps are used to identify the most likely failures, not necessarily all the failures. Of course, the number of failures within this analysis is dependent on th criticality of the FMEA focus.

Once the appropriate mitigation tasks have been selected, formally documenting these tasks has proven to be a key factor to a successful implementation of the tasks.

This formal document is the basis for an optimal predictive maintenance PdM and preventive maintenance PM plan. This optimal maintenance plan should identify any maintenance tasks currently being performed since this will impact the implementation plan. Finally, this formal document should also include any spares or specialized training needed for personnel operations and maintenance to execute the maintenance plan.

Following the completion of the Reliability-centered maintenance analysis, all data is compiled, which makes it possible to document the requirements related to the specific design and maintenance of all key assets. While traditional improvement approaches already address these types of issues, the particularity of Reliability-centered maintenance lies in the step-by-step framework it provides, which allows all issues to be addressed at the same time, as well as involving all stakeholders.

In conclusion, RCM is based on precise organization and standards: the use of a next-gen maintenance management solution such as Mobility Work CMMS supports you in planning interventions, managing document, generalizing best practices and quality standards, measuring KPIs and decision-making.

Join us. Log in. What is RCM? Definition and implementation Born in the aeronautics sector in the s and later generalized to other industries, RCM involves the use of various tools well known to maintenance professionals, including FMECA Failure Modes, Effects and Criticality Analysis and the decision tree.

Before even starting the RCM analysis, the following questions should be asked: What are the normal operating and performance standards of the piece of equipment? How does the piece of equipment not meet these standards? What are the causes? What are the consequences? How to anticipate these failures?

What action can be taken to overcome the lack of a proactive solution?
