RCM is a structured approach that determines the most cost-effective maintenance task for every potential failure in an installation. It focuses on identifying proactive maintenance actions that reduce the probability and consequences of failures. The process involves analyzing failure modes, their operational impacts, and costs to determine optimal tasks like condition-based or time-based maintenance to avoid safety issues, production losses, and costs over time. RCM prioritizes safety and aims to cost-effectively maintain acceptable levels of system operability.
Reliability Centered Maintenance (RCM) is a process that determines the best policies for managing asset functions and failures. It considers all asset management options like condition monitoring, scheduled restoration, and scheduled discard. RCM provides the optimal mix of reactive, time-based, condition-based, and proactive maintenance practices. When applied to commercial airlines in the 1970s, RCM reduced equipment-related crashes from 40 to 0.3 per million take-offs.

Reliability-centered maintenance (RCM) & Total Productive Maintenance (TPM).pptxSamuel Gher
Two effective theories for maximising equipment care are Reliability-Centered Maintenance (RCM) and Total Productive Maintenance (TPM). Using a data-driven methodology, RCM assigns specific maintenance activities based on the prioritisation of important equipment and the analysis of possible breakdowns. Imagine it like a specialised physician locating and treating particular weak points. TPM, on the other hand, uses employee engagement to promote a continuous improvement culture. Everyone assumes responsibility for maintaining the equipment, from operators doing routine upkeep to quality specialists identifying the underlying causes of defects, much like a well-trained team. Both strive for maximum equipment efficiency, while TPM places more emphasis on cultural change and RCM emphasises accuracy. The best strategy for you will rely on your unique requirements. TPM works best with widespread participation, while RCM excels with vital equipment. In the end, integrating these ideas can result in a really strong

The document proposes clustering machines, distinguishing critical machines, integrating PM with production planning, and training technicians to help reduce downtimes and improve PM effectiveness.
IRJET- Maintenance and Reliability Strategy of Mechanical Equipment in IndustryIRJET Journal
This document discusses maintenance and reliability strategies for mechanical equipment in industry. It describes four main strategies: run-to-failure, preventive maintenance, predictive maintenance, and reliability-centered maintenance. Preventive maintenance involves periodically inspecting and repairing equipment on a predetermined schedule. Predictive maintenance uses data from sensors to predict failures before they occur. Reliability-centered maintenance analyzes all possible failure modes for each piece of equipment to customize maintenance plans. The strategies are compared in terms of pros, cons, and cost to implement. Reliability-centered maintenance provides the most efficient maintenance schedule but requires the most resources to execute properly.

Maintenance and service-related items are often the second-largest budget element in a laboratory after salaries and benefits
The document discusses various types of maintenance including preventive, corrective, condition-based, predictive, reliability-centered, and value driven maintenance. It explains that preventive maintenance involves maintaining equipment before failures occur to prevent downtime and costs, while corrective maintenance repairs equipment after failures. Condition-based maintenance uses indicators to determine when equipment will fail and prioritizes maintenance. Predictive techniques help determine equipment condition to schedule maintenance. Reliability-centered maintenance aims to improve cost-effectiveness and uptime. The 5S methodology focuses on effective workplace organization through sorting, setting in order, shining, standardizing, and sustaining these practices.
Reliability engineering is concerned with ensuring systems and components function as intended for a specified period of time. It involves tasks like requirements specification, design, testing, and maintenance to analyze and improve reliability. A reliability engineer identifies potential failure modes and assesses risks to reduce costs from downtime and repairs. Key responsibilities include advising on new installation designs, participating in risk management, and developing engineering solutions to recurring problems. Reliability engineering differs from safety engineering in considering a broader set of hazards focused on costs rather than severe accidents.

Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...IJECEIAES
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
Low power architecture of logic gates using adiabatic techniquesnooriasukmaningtyas
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.

In general, failures affect operations in four ways:
they affect total output. This occurs when equipment stops working altogether or when it works
too slowly. This results either in increased production costs if the plant has to work extra time to
catch up, or lost sales if the plant is already fully loaded.
they affect product quality. If a machine can no longer hold manufac- turing tolerances or if a
failure causes materials to deteriorate, the likely result is either scrap or expensive rework. In a
more general sense, "quality" also covers concepts such as the precision of navigation sys- tems,
the accuracy of targeting systems and so on.
they affect customer service. Failures affect customer service in many ways, ranging from the
late delivery of orders to the late departure of passenger aircraft. Frequent or serious delays
sometimes attract heavy penalties, but in most cases they do not result in an immediate loss of
revenue. However chronic service problems eventually cause customers to lose confidence and
take their business elsewhere.
increased operating costs in addition to the direct cost of repair. For instance, the failure might
lead to the increased use of energy or it might involve switching to a more expensive alternative
process.
5. Proactive Maintenance:
The nature and severity of these effects govern the way in which the failure is viewed by the
organisation. The precise impact in each case - in other words, the extent to which each failure
matters - depends on the operating context of the asset, the performance standards which apply to
each function, and the physical effects of each failure mode.
Proactive maintenance has much more to do with avoiding or reducing the
consequences of failure than it has to do with preventing the failures themselves
A proactive task is worth doing if it deals successfully with the consequences of the
failure which it is meant to prevent
This of course presupposes that it is possible to anticipate or prevent the failure in the first place.
Whether or not a proactive task is technically feasible depends on the technical characteristics of the
task and of the failure which it is meant to prevent.
6. Hidden and Evident Failures
Failures of this kind are classed as evident because someone will eventually find out about it when they occur
on their own. This leads to the following definition of an evident function:
An evident function is one whose failure will on its own eventually and inevitably become evident
to the operating crew under normal circumstances.
A hidden function is one whose failure will not become evident to the operating crew under
normal circumstances if it occurs on its own.
7. Categories of Evident Failures
Evident failures are classified into three categories in descending order of importance, as
follows:
Safety and environmental consequences: A failure has safety consequences if it could hurt
or kill someone. It has environmental consequences if it could lead to a breach of any
corporate, regional or national environmental standard
Operational consequences: A failure has operational consequences if it affects production
or operations (output, product quality, customer service or operating costs in addition to the
direct cost of repair)
Non-operational consequences: Evident failures in this category affect neither safety nor
production, so they involve only the direct cost of repair.
By ranking evident failures in this order, RCM ensures that the safety and environmental
implications of every evident failure mode are considered. This unequivocally puts people
ahead of production.
8. Safety and Proactive Maintenance
For failure modes which have safety or environmental consequences, a
proactive task is only worth doing if it reduces the probability of the failure to
a tolerably low level
9. Operational consequences
In general, failures affect operations in four ways:
they affect total output. This occurs when equipment stops working altogether or when it works too slowly. This results
either in increased production costs if the plant has to work extra time to catch up, or lost sales if the plant is already
fully loaded.
they affect product quality. If a machine can no longer hold manufac- turing tolerances or if a failure causes materials
to deteriorate, the likely result is either scrap or expensive rework. In a more general sense, "quality" also covers
concepts such as the precision of navigation sys- tems, the accuracy of targeting systems and so on.
they affect customer service. Failures affect customer service in many ways, ranging from the late delivery of orders
to the late departure of passenger aircraft. Frequent or serious delays sometimes attract heavy penalties, but in most
cases they do not result in an immediate loss of revenue. However chronic service problems eventually cause customers
to lose confidence and take their business elsewhere.
increased operating costs in addition to the direct cost of repair. For instance, the failure might lead to the increased
use of energy or it might involve switching to a more expensive alternative process. In non-profit enterprises such as
military undertakings, certain failures can also affect the ability of the organisation to fulfil its primary function
sometimes with devastating results.
Certain functions can effect the primanry functions of the organization that can have devastation results
"For want of a nail, a shoe was lost. For want of a shoe, a horse was lost. For want of a horse, a message was
lost. For want of a message, a battle was lost. For want of a battle, a war was lost. All for want of a horseshoe
nail."
10. The severity of these consequences mean that if an evident failure does not
pose a threat to safety or the environment, the RCM process focuses next on
the operational consequences of failure.
A failure has operational consequences if it has a direct adverse effect on
operational capability
11. Avoiding Operational Consequences
Avoiding Operational Consequences The overall economic effect of any failure mode
which has operational consequences depends on two factors:
⚫ how much the failure costs each time it occurs, in terms of its effect on operational
capability plus repair costs
⚫ how often it happens. In the previous section of this chapter, we did not pay much
attention to how often failures are likely to occur.
(Failure rates have little bearing on safety-related failures, because the objective in
these cases is to avoid any failures on which to base a rate.) However, if the failure
consequences are economic, the total cost is affected by how often the consequences
are likely to occur. In other words, to assess the economic impact of these failures, we
need to assess how much they are likely to cost over a period of time.

RCM:
The response priority matrix is as follows:
Priority Description Response time
1. Emergency Same day
2. Urgent 5 days
3. High Priority 15 days
4. Routine 30 days
5. Deferred 90 days
13. RCM --> structured approach that determines the
most cost-effective maintenance task for every
(possible) failure of the installation
In essence, it is the process used to determine the most effective approach to
maintenance by identifying actions that, when properly instituted will reduce
the probability of failure and which are most cost effective. (NASA RCM
Guide, 2000)
14. RCM --> structured approach that determines the
most cost-effective maintenance task for every
(possible) failure of the installation
Reliability-centered maintenance analysis provides a basic framework for
analyzing the functions and potential failure modes for a physical asset in
order to develop a scheduled maintenance plan that will provide some
acceptable level of operability. (The term “acceptable level” needs to be
defined by each individual organization based on their individual needs of
whatever system it is that they wish to measure.) In addition, reliability-
centered maintenance should also take into account risk in some efficient,
cost-effective manner.
15. RCM --> structured approach that determines the
most cost-effective maintenance task for every
(possible) failure of the installation
A well crafted reliability-centered maintenance program should (or could
depending on the size of the organization) incorporate
condition based actions,
time based actions,
and run to failure. (NASA RCM Guide, 2000).

3.2.1 Cost The consideration of economic aspects of a component is the major
factor in its criticality. The total cost of a component with respect to maintenance
in the manufacturing industry includes
(a) maintenance cost
(b) component investment cost and
(c) cost of production loss.
In comparison to other components, if a component has a higher maintenance cost
then it needs to be assigned a higher criticality value. Maintenance cost directly
affects the availability of resources of repair and complexity of the
component. Cost of production also directly depends on total downtime of the
system, which is controlled by the availability of resources to repair. Next, to
maintenance cost, cost of production loss and component investment cost are
assigned criticality values respectively
19. 3.2.2 Functional dependencies According to these criteria, the functional
dependence of a component in terms of process and their design is one of the main
factors in finding a critical component of a system. The design of a component has
its significant contribution in the system reliability indices. If a component is having
the leading role in the system but if the design of the component is not reliable,
then that particular component was assigned to be more critical from a design point
of view.
3.2.3 Complexity To ensure the smooth operation of a manufacturing system, the
complexity of the component is of a great concern. This criterion is divided into
three sub-criterion as the probability of failure, total no. of parts and their failure
effect on the system. Component multiplicity will play an important role in finding
out the critical component. Amodule, which is having a large number of parts, will
have a significant contribution in the overall system reliability. In addition, at the
same time, the failure frequency and their effect on the system will affect the
system availability. A component with large no. of parts and high failure probability
is much more critical to maintain.
20. 3.2.4 Maintainability The fourth criterion is maintainability. Maintainability is
also having a significant role in identifying the critical component of a
manufacturing system. This criterion further classified into four sub-criteria
as the availability of technical specification, failure detection, total
downtime and facility required to repair. The repair process of some
components can sometimes take a long time resulting in large downtimes of
the system. In some cases, specific failures are difficult to detect because of
less availability of technical specification. In such cases, when a failure
occurs, the time to repair will considerably increase and will be difficult to
maintain the entire system up to the desired level of functioning. Hence, the
component having the large downtime assigned to be more critical.
21. 3.2.5 Safety impact While identifying the critical component of any system,
safety impact is of great concern. This criterion is classified into three sub-
criteria, human safety, resources safety, and environment safety. In case of a
manufacturing system, human and resource safety have significant roles while
environment safety also needs to be considered because of cooling systems.
The increasing requirements of maintenance in the unproductive use phase of
the product lifecycle of manufacturing systems produce a significant impact
on the environment as the defective parts; used oils, grease and cleaning
agents are discarding into the environment. If any accidents happen during
any process, it will directly affect the human beings. Hence, the safety factor
considered, while performing the criticality analysis of any system
22. HOW TO INITIATE RCM
1.Develop a Master equipment list identifying the equipment in your facility.
2.Prioritize the listed components based on importance or criticality to operation,
process .Assign components into logical groupings.
3.Types of Maintenance Programs
4.Determine the type and number of maintenance activities required and periodicity
using:
a. Manufacturer technical manuals.
b. Machinery history.
c. Root cause analysis findings - Why did it fail?
d. Good engineering judgment.
5.Assess the size of maintenance staff & Identify tasks that may be performed by
operations maintenance personnel.
6.Analyze equipment failure modes and impacts on components and systems.
7.Identify effective maintenance tasks or mitigation strategies.
23. Root Cause Analysis
A root cause is the fundamental cause, which, if corrected, will prevent
recurrence of this and similar events. This is usually not a barrier/ control
problem but a weakness or defi ciency in the identifi cation, provision or
maintenance of the barriers/controls or the administrative functions.
A root cause is ordinarily control-related involving such upstream elements as
management and administration. In any case, it is the original or source
cause.
Editor's Notes
The nature and severity of these effects govern the way in which the failure is viewed by the organisation. The precise impact in each case -
in other words, the extent to which each failure matters - depends on the operating context of the asset, the performance standards which apply to
each function, and the physical effects of each failure mode. This combination of context, standards and effects means that every
failure has a specific set of consequences associated with it. If the consequences are very serious, then considerable efforts will be made to prevent
the failure, or at least to anticipate it in time to reduce or eliminate the consequences. This is especially true if the failure could hurt or kill some-
one, or if it is likely to have a serious effect on the environment. It is also true of failures which interfere with production or operations, or which
cause significant secondary damage. On the other hand, if the failure only has minor consequences, it is possible that no proactive action will be taken and the failure simply corrected each time it occurs.
This suggests that the consequences of failures are more important than their technical characteristics. It also suggests that the whole idea of proactive maintenance is not so much about preventing failures as it is
about avoiding or reducing the consequences of failure. Proactive maintenance has much more to do with
avoiding or reducing the consequences of failure than it has to do with preventing the failures themselves
