Enhancement of the performance of an industry by the application of tqm conceptseSAT Journals
Abstract Nowadays many companies are unable to prove their performance, because they do not practice the TQM concepts in- total. In order to increase the awareness, certain TQM techniques are suggested to enhance overall performance of the organisations. Here an effort is made to apply two important basic concepts of TQM which are i)continuous improvement of production process by applying newer and innovative methods ii)establishing performance measures for the processes .This paper uses the real experimental results of cartons making industry which comprises the four machines such as Printing , Punching , Gluer and Lamination machines. We get all the machines input and output details, and then made certain suggestions based on the input values of all the four machines. Presently the four machines output values such as Availability, Performance, Quality and Overall Equipment Effectiveness are very low compared with the world class industry. In order to increase them it is suggested to reduce the downtime and other non-productive time by adopting certain simple TQM techniques. The new improved values found to be much higher than the existing values. Keywords: Total Quality Management, Availability, Performance, Quality, Overall Equipment Effectiveness, Quality Improvement.

Review of Implementation of lean manufacturing in cement industryijsrd.com
Implementation of lean helps many organizations to improve their productivity and efficiency; on the other hand number of organizations has failed to benefit from lean philosophy. The case of not achieving the expected results of implementing lean is not because of limitation of lean to specific organizations type; but it is the misconception of lean philosophy. The lean thinking was first implied in the automobile companies and it widely spreads within the all types of industries; however the today's challenge is to implement the lean philosophy within continuous manufacturing industries and different organizations regardless to the type and size of the organization. This has motivated me to apply lean philosophy to the continuous industry i.e. cement industry. The cement industry is an example of the continuous industry sector and it will be used to convey that the lean philosophy is applicable to all deferent organization types. There are many problems the cement industry facing in today's cut throat competition; one of the major challenges is the capability of the cement industry to adopt techniques by which the overall improvement can be achieved. The need for improving the productivity of the cement production line is to reduce the downtime rates, and satisfy high demands of consumers. This research has aimed that the lean philosophy is beneficial to cement industry once the organization aims, and objectives are clarified and communicated through all levels of the organization. Furthermore barriers and obstacles should be removed by changing the organizational culture, and empowering the people to be involved in identifying and problem solving process.

Multi criteria Decision model (MCDM) for the evaluation of maintenance practi...IJERA Editor
The perceptible impact of Total Productive Maintenance (TPM) lies in raising productivity standards, gaining
profitability, and improving the quality besides cutting down the non value added costs greatly. This paper is
an attempt to provide a frame work and pragmatic approach in implementation of TPM. A number of novel
success factors or practices that are responsible for the decisive role to overture the process are identified.
These practices are interchangeably called as sub-attributes. These practices must have evolved from different
strategies. The sub-attributes are quantified using least square multi attribute decision model (LSMADM) for
three alternatives strategies viz. corrective maintenance, reliability centered maintenance(RCM), and TPM. Any
sub-attribute irrespective of its own high or low relative score among the number of sub attributes is evaluated
over three alternative strategies. To implement any sub-attribute, an investigation of its highest relative score
for given alternatives will guide the managers to opt the best alternative. The best practices must come from
different strategies to get most optimal results. The priorities established using LSMADM will act as base line
to implement the industrial activities in a more systematic and balanced way to gain far-reaching optimized
productivity and quality standards. The higher priority task will be given higher consideration in terms of
committing the resources vis a vis less priority task. This will aid in orienting the collective efforts for optimal
outcomes.

In the recent era of globalisation and competitive scenario, quality plays a vital role in
ensuring customer satisfaction. Total quality management (TQM) involves the
implementation of appropriate tools/techniques to provide products and services to
customers with best quality. In order to ensure the success of TQM practices in a
modern automotive component manufacturing scenario, barriers and their mutual
interactions need to be systematically analysed to enable practicing managers for
effective deployment. In this context, this study depicts an interpretive structural
modelling (ISM)-based approach to understand the mutual influence of TQM
barriers. A total of 21 barriers have been identified for TQM practices and ISM
model has been developed. The barriers are grouped under four categories
(dependent, independent, autonomous and linkage) based on MICMAC analysis. The
conduct of the study enabled the decision-makers to systematically analyse the
influential barriers for effective deployment of TQM concepts in modern automotive
component manufacturing, which is one of the rapidly growing sectors in the Indian
scenario.

Introduction
During the past decade, manufacturing organisations have been adopting total quality
management (TQM) as a philosophy for bringing about quality improvements. TQM
enables the organisations to attain business excellence. TQM emphasises continuous
improvement as one of the top goals and it enables organisations to achieve business excel-
lence. TQM includes guiding principles and management practices that lead to continuous
improvement in quality and providing quality products to customers. TQM focuses on
management commitment and involvement, customer focus, teamwork, motivation and
employee involvement. In addition, modern automotive manufacturing organisations
have adopted advanced quality tools such as Quality Function Deployment, Failure
Mode and Effect Analysis and Six Sigma. In order to compete in the globalised market,
the organisations must inculcate TQM concepts into all activities of the organisation effec-
tively (Mahapatra & Sekhar, 2004). TQM practices have been widely acknowledged as a
disciplined management process in different sectors such as manufacturing, and service in
order to deal with changes in the marketplace and focus on product and service quality. It
provides a set of guidelines that will ...

It also analyzes common indicators of successful lean implementation and discusses the concept of critical success factors.
(3) The article synthesizes critical success factors identified in previous research, finding the most common to be top management commitment, culture change, training, communication, teamwork ability, understanding lean tools, and continuous improvement
This document summarizes an article from the International Journal of Management that proposes developing a computational tool to support minimizing waste in production processes using lean principles and knowledge management. It reviews literature on lean methodology, knowledge management, and knowledge-based systems. The proposed tool would identify improvements across the entire production process and reduce waste by organizing knowledge extracted from value stream mapping. The goal is to reorganize management processes and generate profits by reducing waste identified in the value stream map.

Multi criteria Decision model (MCDM) for the evaluation of maintenance practi...IJERA Editor
The perceptible impact of Total Productive Maintenance (TPM) lies in raising productivity standards, gaining
profitability, and improving the quality besides cutting down the non value added costs greatly. This paper is
an attempt to provide a frame work and pragmatic approach in implementation of TPM. A number of novel
success factors or practices that are responsible for the decisive role to overture the process are identified.
These practices are interchangeably called as sub-attributes. These practices must have evolved from different
strategies. The sub-attributes are quantified using least square multi attribute decision model (LSMADM) for
three alternatives strategies viz. corrective maintenance, reliability centered maintenance(RCM), and TPM. Any
sub-attribute irrespective of its own high or low relative score among the number of sub attributes is evaluated
over three alternative strategies. To implement any sub-attribute, an investigation of its highest relative score
for given alternatives will guide the managers to opt the best alternative. The best practices must come from
different strategies to get most optimal results. The priorities established using LSMADM will act as base line
to implement the industrial activities in a more systematic and balanced way to gain far-reaching optimized
productivity and quality standards. The higher priority task will be given higher consideration in terms of
committing the resources vis a vis less priority task. This will aid in orienting the collective efforts for optimal
outcomes.

This document summarizes an article about optimizing quality, cost, and time (QCT) in new product development. It discusses how these three objectives are interrelated and often require trade-offs. It proposes using a systematic, analytical approach to quantify the interrelationships between objectives to help with trade-off decision making. This would assess how movement in one objective impacts others. For example, reducing development time could increase costs. The document also discusses using profitability metrics like profitability index, net present value, and payback period to evaluate trade-offs based on long-term profitability. Graphically representing cash flows can help assess trade-offs subject to the specific project's profitability targets.

The document describes applying Quality Function Deployment (QFD) and Analytic Hierarchy Process (AHP) to optimize the design of a ceramic washbasin. QFD was used to determine customer needs and technical requirements through interviews. Key customer needs identified were that the basin should not splash water, be easy to clean, look good, resist bacteria/stains, prevent soap from spilling, and last a long time. AHP was then used to prioritize these customer needs by having customers provide pairwise comparisons. The results will help optimize the basin design to better meet customer wants.

In the recent era of globalisation and competitive scenario, quality plays a vital role in
ensuring customer satisfaction. Total quality management (TQM) involves the
implementation of appropriate tools/techniques to provide products and services to
customers with best quality. In order to ensure the success of TQM practices in a
modern automotive component manufacturing scenario, barriers and their mutual
interactions need to be systematically analysed to enable practicing managers for
effective deployment. In this context, this study depicts an interpretive structural
modelling (ISM)-based approach to understand the mutual influence of TQM
barriers. A total of 21 barriers have been identified for TQM practices and ISM
model has been developed. The barriers are grouped under four categories
(dependent, independent, autonomous and linkage) based on MICMAC analysis. The
conduct of the study enabled the decision-makers to systematically analyse the
influential barriers for effective deployment of TQM concepts in modern automotive
component manufacturing, which is one of the rapidly growing sectors in the Indian
scenario.

Introduction
During the past decade, manufacturing organisations have been adopting total quality
management (TQM) as a philosophy for bringing about quality improvements. TQM
enables the organisations to attain business excellence. TQM emphasises continuous
improvement as one of the top goals and it enables organisations to achieve business excel-
lence. TQM includes guiding principles and management practices that lead to continuous
improvement in quality and providing quality products to customers. TQM focuses on
management commitment and involvement, customer focus, teamwork, motivation and
employee involvement. In addition, modern automotive manufacturing organisations
have adopted advanced quality tools such as Quality Function Deployment, Failure
Mode and Effect Analysis and Six Sigma. In order to compete in the globalised market,
the organisations must inculcate TQM concepts into all activities of the organisation effec-
tively (Mahapatra & Sekhar, 2004). TQM practices have been widely acknowledged as a
disciplined management process in different sectors such as manufacturing, and service in
order to deal with changes in the marketplace and focus on product and service quality. It
provides a set of guidelines that will ...
Relationship and comparison between in jit, tqmprj_publication
The document reviews the relationship and comparisons between Just-in-Time (JIT), Total Quality Management (TQM), and Total Productive Maintenance (TPM). It finds that while the concepts have similarities in their origins, methodologies, tools and effects, they differ in some key areas such as their main theories and approaches. Specifically, JIT focuses on minimizing waste, TQM emphasizes customer and employee involvement, and TPM aims to maximize equipment effectiveness. However, the concepts are also complementary and organizations can benefit from combining elements of each.

The document proposes a modified version of the Manufacturing Cost Deployment (MCD) method called Project Cost Deployment (PCD) for analyzing engineer-to-order (ETO) production systems. The PCD introduces two key modifications: 1) replacing the concept of production stations with manual assembly macro-activities, and 2) introducing a new structure for classifying and analyzing losses specific to manual assembly tasks. The validity of the PCD approach is demonstrated through a real-world industrial application to a train wagon manufacturer. The results show that PCD can identify hidden losses, quantify wastes economically, and estimate the impacts of potential lean improvements in terms of efficiency and effectiveness.

This document summarizes a research article that examines how three contextual factors - plant size, age, and unionization status - influence the implementation of lean manufacturing practices. It identifies 22 key lean practices and groups them into four "bundles" - just-in-time (JIT), total quality management (TQM), total preventive maintenance (TPM), and human resource management (HRM). The study finds that plant size has a strong influence on lean implementation, while the effects of age and unionization are less significant. It also shows that implementing lean practice bundles contributes substantially to operational performance, explaining around 23% of the variation in performance outcomes.

This document discusses a study that examined the relationship between lean manufacturing practices (LMP), manufacturing performance, and the moderating role of ethical climate among Malaysia's manufacturing organizations. The study collected data from 335 manufacturing organizations and analyzed it using PLS-SEM techniques. The results found a positive relationship between LMP and manufacturing performance. It also found a positive relationship between ethical climate and manufacturing performance. However, ethical climate did not significantly moderate the relationship between LMP and manufacturing performance, though further analysis showed it may do so under different conditions. The study contributes to understanding these relationships in Malaysian manufacturing contexts and the potential moderating role of ethical climate.

Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...PriyankaKilaniya
Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.

Applications of artificial Intelligence in Mechanical Engineering.pdfAtif Razi
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.

ABSTRACT
The purpose of this study is to develop a new model to provide guidance and support for Indian manufacturing
companies who aim to reach at global level standards both in maintenance and manufacturing processes through
continual improvement. Based on this study, a strategic model was developed through conceptual integration of
popular process improvement strategies, which are based on ISO, TQM, TPM , Lean Production, six-sigma &
TPM. An attempt was made to analyze and address some major limitations of existing models to pave the way
of achieving manufacturing excellence.
Keywords:Manufacturing, Kaizen, JIT, six-sigma, lean, Agile manufacturing, TQM, total productive
maintenance, world-class, model.
I. INTRODUCTION
The word “World Class“ was coined by
Hayes & Wheelwright (1984) to describe the
capabilities of an organization which follows certain
proven methodologies by similar companies. Japan
has been considered as the model of best practice
using countries in manufacturing after the World
War I (Tauguchi et all). It goes without saying that,
becoming a world-class manufacturing (WCM)
company is a common industrial goal. Many
companies are trying to adopt this philosophy in
their production process to be the best in the world
within their particular sector of industry. Kodali et
al. (2004), by performing a comprehensive
performance value analysis on WCM and other
advanced manufacturing system such as job shop
(JS), agile manufacturing, transfer line (TL),
computer integrated manufacturing (CIM) Systems
and group technology(GT) demonstrated that the
WCM is the best alternative for implementation and
to achieve or maintain competitive advantages. A
review of the literature shows that there is no
universally recognized definition of WCM and
different researchers have different views about
WCM as the best manufacturing practice varies from
organization to organization. The problem which is
common in attempts of defining the concept of
world class manufacturing is how to interpret the
measures within the operating context of the firm
(Harrison, 1998). However, the description of WCM
by Sinha and Sinha (2007) can be a clue for
understanding the scope of WCM concept. They
stated that the term WCM is applied for
organizations that achieved a global competitive
advantage through the use of best practice
manufacturing capabilities. This improved
competitiveness in the broadest sense is referred to
as manufacturing excellence and is deemed to be
demonstrated by simultaneous improvements in
manufacturing performance as well as business
performance through indicators, such as
productivity, cost reduction and market share. If the
firm continues to excel in manufacturing, it may
dominate world markets, in which case it would be
called a world class manufacturer. Coping with the
ever changing conditions of today’s markets have
led to significant emphasize on production
flexibility. In this regard, traditional manufacturing
practices have been replaced with highly automated
processes and also application of Lean and just-in-
time (JIT) production strategies have led to
minimum inventory buffers. In such environment,
reaching to superior performance in manufacturing
requires near 100 percent uptime. On the other hand,
without excessive inventory buffers, unscheduled
equipment downtime usually costs 10 to 20 times
what the same equipment downtime costs in old
traditional batch processing or functional
departments (Cooper, 2004). This is due to the fact
that each equipment failure could results directly and
immediately in lost sale opportunity, failed shipping
schedules and loss in customer satisfaction. Hence, it
is also becoming increasingly difficult to ignore the
role of maintenance on the way of manufacturing
excellence. In fact, reaching to world-class
performance in maintenance is an important
prerequisite for WCM since there is a direct
relationship between these two that without one,
reaching to second would face serious problems. So
far, most studies in the field of world-class have only
focused on manufacturing, and researchers have not
treated “world class concept in maintenance in much
detail. Mostly each of them has studied
predominantly as independent methods based on

specific situations in application. Hence, this paper
aims to examine the integration of these popular
process improvement.
II. REVIEW OF EXISTING MODELS
Embarking on a journey towards WCM
without precise roadmap is very risky according to
Sharma and Kodali (2008, p. 51), lack of “practical
pursuit of excellence within manufacturing." So far,
many researchers have realized the importance of
this issue and developed models to assist
organizations in the way of reaching to their
manufacturing performance objectives. However,
most of the early models could not be used due to
narrow elements' consideration. Gradually, the
WCM models were improved by covering more
detailed conditions but yet could address only the
issues pertaining to individual industry. Schonberger
(1986) is known as one of the pioneers in devising
WCM models and in which he devised first
integration of tools to achieve the overall
performance. However, according to Nachiappan et
al. (2009), implementation of JIT at the beginning
stage of the model, un-clarified method and
sequence of implementation can cause failure in
many industries. Schonberger (1996) also introduced
16 principles of customer-focused ” or“ principles-
based management” that firms can use as WCM
achievement criteria. For each of the 16 principles,
there is a five-point scale, with 5 being the highest
level of attainment. Any firm that scores more than
67 points is thought to be in the stage of maturity.
Although, it is argued by Muda and Hendry (2002)
that scoring systems such as that suggested by
Schonberger (1996) can lead to misleading results if
some of the underlying assumptions do not apply to
particular types of company. Gunn (1987) presented
another simple model that relies on three pillars:
computer integrated manufacturing (CIM), total
quality control/management (TQC/TQM) and JIT
production methods. He believed that these are three
fundamental approaches in modern manufacturing,
which may enable an organization to gain
competitive. Farsijani and Carruthers (1996) also
developed a WCM through a conceptual model for
their successful model which shows the growth of
techniques and factors integration. Associated with
the concept of WCM, this model is the remainder of
this paper is organized as follows: actually an
upgraded toolbox from 1980 onwards, with first, a
review of the literature in relation to integration of
respect to the industrial environment and
organizational Secondly, an overview about current
WCM models to achieve a better understanding of
existing models was provided. In addition, the
design and development of an integrated Lean
Sigma Productive Maintenance (LSPM) model was
chronicled. Also, the evaluation of the model for its
effectiveness through comparative analysis
comprehensive researches to provide a model for
management principles and resources and also key
initiatives for organizations to be world class. A total
of 23 models and around 252 unique elements of
WCM were participated in their analysis. Based on
the comparison, it was found that only a few of the
models are similar and in the majority of the models,
the naming and number of elements differ
significantly. So they classified the 12 pivotal
elements as pillars of WCM based on the frequency
of participation in different models and the rest as
sub-elements which were grouped under various
pillars. However, it is argued by Nachiappan et al.
(2009) that WCM models which are proposed by
different authors have followed the trial-and-error
approach, and they just cover need-based
requirements. They also added that lack of clear
consensus and systematic reason or background in
the process of selection of tools to form WCM
models, has resulted in an inconsistency between
different tools and techniques, and increased the
chance of unavailing implementation in various
conditions. Therefore, in order to minimize the
number of tools which constitute WCM model and
yet maximize the effectiveness of their combination,
a statistical survey was conducted in a leading
multinational automotive company in India on 10
most recognized WCM tools. The results showed
that the combination of total Quality Management
(TQM), total productive maintenance (TPM), six-
sigma and lean manufacturing gain more than 40
percent weight in addressing manufacturing system
requirement for achieving world- class status. They
also concluded that each of these three tools
individually has more contributions in basic
components of manufacturing systems (man,
machine, method, material and operating
environment) in comparison with the remaining
seven WCM tools. According to Ross (1991), in
order to achieve the world-class status, the number
of tools and elements employed in the organization
must be minimum in number and maximum in
effect. Hence, it can be concluded that the model
developed by Nachiappan et al. (2009) is the most
effective one; so it was taken as a starting point in
developing a new model based on the concepts of
TQM/TPM, six-sigma and lean. In this report, the
synergistic effects of these methodologies were
investigated. From the literature survey, it is inferred
that direct application of current WCM models may
be faced with some major limitations. The
limitations may be caused by pillars of a model, or
type of industry for which the model is designed. In
other words, the applied strategies of each model
could influence the performance and universality of
the WCM model.

Consequently, the focal point of this study
is to develop a new model to rectify the deficiencies
of previous studies. This model is supposed to have
some critical features such as being easy to apply;
being able to restrict implementation costs based on
certain circumstances of a company in terms of size,
skill and industry; being intelligible for everyone
who is involved in the process and increasing overall
efficiency of technical systems. The model will be
evaluated subsequently for its effectiveness, through
verification of benefits and strengths of the new
model compared with current similar models.
III. MODEL STRATEGIES
Integration of six-sigma and lean
Both lean and six-sigma are two recognized
business process improvement strategies which are
adopted by many organizations for achieving
superior performance in quality, cost and time of
manufacturing operations (Thomas et al., 2008;
Kumar et al., 2006). But lean and six-sigma
approaches have often been used in separation or
sequential manner (Smith, 2003), which causes
establishing two different ways to reaching one goal
that results in a conflict of interest and consuming
resources ineffectively or excessively (Bendell,
2006). In addition, over the last decades, many
organizations have deployed either six-sigma or lean
and tried to renovate their operating and supporting
systems based on these strategies. After achieving
initial rapid growth in market share and competitive
advantages, gradually the velocity of this growth has
reached to a point of diminishing return in such a
way that further improvements are not readily
generated. Hence, these organizations have faced
with the necessity of finding another source of
competitive advantage (Arnheiter and Maleyeff,
2005). Therefore, once the apparent benefits of lean
and sixsigma were brought to the attention of the
business world, lean and six-sigma practitioners
integrated the two strategies into a more powerful
and effective hybrid way, overcoming the limitations
and retaining most of the strengths of each strategy.
The phrase- Sigma & Lean is to describe the
integration of lean and six-sigma philosophies
(Sheridan, 2000). There is little literature available
on the integration of these concepts when looking
for a “common model, the mutual content or
method” (BeWheat et al. (2003) stated that both lean
and six-sigma have some similarities in their
ultimate goal, which help six-sigma to have a
complementary role for Lean philosophy in such a
way that provides tools and procedures to overcome
specific problems along Lean journey. Pepper and
Spedding (2010) mentioned that using either one of
them alone has limitations; while Six- Sigma will
eliminate defects, it will not address the question of
how to optimize process flow. Furthermore, six-
sigma in itself does not consider the needs of
customers and can be said that it has been potential
to lose sight of the customer if not implemented
along lean principles. On the other hand, lean
principles exclude the advanced statistical tools
often required to achieve the scales sensitivity to
small changes duplication of RPN reliability, has
adopted different approaches from time-based
maintenance (PM) and condition monitoring
methods to the recent maintenance approaches that
focus more on application of risk measuring
methods in maintenance such as risk based
inspection (RBI), periodic maintenance optimization
(PMO), and reliability centered maintenance (RCM).
By deep pondering upon these methods, it can be
seen that all of them are based on subjective
estimation of risk and prioritization via specific
models and charts like failure mode effect analysis
(FMEA) charts. However, FMEA charts with
heavily relying on RPN methodology for ranking
and assessing the risk of potential failure modes,
have many defects that gradually are fading from the
field of maintenance. According to Bowles (2004),
although RPN technique is simple, easy to
understand, straight forward to use and well
documented from the management viewpoint, but
from the technical perspective, it is seriously process
capabilities needed to be truly 'Lean'. However,
Arnheiter and Maleyeff, (2005) argued that a crucial
aspect of integrating these two continuous
improvement approaches is retaining equilibrium
between them. The balance lies in creating sufficient
value final product from manufactured the by
customer’s the company and viewpoint so that
market share is maintained, while at the same time
reducing variation to acceptable levels so as to lower
costs incurred, without over-engineering the
processes. Smith (2003) also represented some of the
successful case studies in lean six-sigma application
that the beneficiaries have experienced significant
results from a combined approach to improvement.
However, the main point in these case studies is that
almost in all satisfactory experiences, one of the
techniques became predominant over the other, on
the way of improvement. Moreover, there is no
specific model for answering the questions of where
and in what applicable. Kumar et al. (2006) have
also presented a case study undertaken by
implementing a lean sigma model into an Indian
small to medium sized enterprises (SME) in order to
reduce the defects which occur in the thus satisfy
their customers. They suggested that within SME
environment, while lean organizes and simplifies the
processes, tries to eliminate wastes, reduces overall
complexity and helps to clarify value-added
activities, sixsigma can solve complex cross
functional problems where the root causes of a
problem (in this case, crack propagation) is unknown

and help to reduce undesirable variations in
processes.the scales, sensitivity to small changes,
duplication of RPN numbers and problems with
comparing different RPNs. Bowles (2004) also
argued that because of these deficiencies, the results
of this technique are not only meaningless but are, in
fact, misleading. So it is highly recommended to
drop this approach and different prioritization
technique being used. Deploying the concept of Six-
Sigma into equipment reliability / maintenance
applications has emerged lately, since this
methodology has traditionally been limited to
manufacturing and administrative processes (Al-
Mishari and Suliman, 2008). Six- Sigma is
considered as a strong alternative approach that
mainly focuses on statistical deduction rather than
subjective judgment. Hence, many researchers have
been done to show the successful intervention of
Six-Sigma in manufacturing, service sector (e.g.
healthcare) and also for reliability applications
(Revere, 2000). By comparing the six-sigma
approach With existing methods Such as reliability
centered Maintenance (RCM), it can be seen that
unlike risk- centered methods, which focus on
judgment, and unlike reliability/statistical analysis,
which relies heavily on numerical data, six-sigma
provides an integral mix of both valuable resources
of information Al-Mishari and Suliman2008).
Overall, review of recent works shows that sixsigma
is appropriate to be used in maintenance
management concept considering different aspects
such as, statistical evaluation.
Integration of TPM & Lean:
Both lean and TPM had evolved in parallel
from their Early concepts and are coming together
towards a common goal that is specifying areas of
hidden wastes that is - any human activity, which
absorbs resources but creates no value. Moreover,
both are approaches that spanned all over the
company and cover a wide Spectrum of techniques.
They have both achieved significant results by
delivering practical solutions to different business
issues. Although the origin of them is different,
having progress in each of them depends on
clarifying wasteful behaviors and practices
McCarthy and Rich, 2004). TPM acts as a bridge
between lean Thinking and maintenance to improve
efficiency and reduce wastes. This approach
provides a synergistic relationship among all
particularly between production and maintenance.
Ferrari et al. (2002) have emphasized upon lean and
TPM as two methodologies that can work together to
provide a holistic approach to continuous
improvement. While lean thinking tools improve the
design efficiency of transformation processes that
provide greater customer value with less effort
(Womack and Jones, 1996), TPM tools enhance the
effectiveness of this transformation process by
improving capacity, increasing control and
repeatability (Willmott and McCarthy, 2000). So
synergy of the two approaches can develop both
operational efficiency and organizational
effectiveness. Hence, it can be concluded that each
of six-sigma, lean and TPM has a significant
synergistic effect on the others and when integrated
in one model, can be substantially effective in
addressing all types of process problems and
necessary factors to achieve world-class status in
both manufacturing and maintenance.
Developing a New WCM Model
Ensuring the availability and reliability of
the equipment at the time of requirement, plays the
most fundamental role in reaching to outstanding
performance in manufacturing. So the journey
towards excellence in manufacturing should be
started from striving for reaching to world class
maintenance. The term of world class when comes
to maintenance, means the best model to reach the
sixsigma level in maintenance of Rall,2005).
Initially, it is necessary to consider company’s
mission statement a translating the mission and
vision into a set of objectives and performance
measures that can be quantified and appraised by
using balanced scorecard methodology as a strategic
management tool.
Contribution of TPM and SIX-SIGMA
Application of TPM concept in the process
of reaching to World class maintenance is inevitable.
Besides, the integration of six-sigma concept with
TPM in the model is presented by using PDCA
driven cycle called, DMAIC process of
performances improvement. Six-Sigma forms the
basic foundation for the TPM strategy and make it
easier to understand by shop floor operators who are
the most important enablers of successful TPM
implementation. Within phases of DMAIC, various
problems and circumstances of the maintenance
department are defined, the performance of the
process is measured, the most important causes of
defects are analyzed, improvemen t or corrective
actions are taken and the improvements are
maintained by continuous controlling. Moreover, the
iterative process of DMAIC is used as the main
operational approach for the implementation of this
model in order to have permanent improvement of
maintenance activities and ideally the company’s
functions, but Reaching to Six-Sigma process
performances. Furthermore, many six-sigma, lean
and quality advanced supportive tools are used in the
improvement process, to enhance the performance of
both manufacturing and maintenance operations.
Adding Lean concept to the scenario

Integration of TPM and Six-Sigma, which
result in fewer variations in a process and reaching
to process stability directly influences the
effectiveness of lean implementation in eliminating
wastes and reducing the amount of raw, WIP and
finished goods inventories. Due to these
complementary interactions, the proposed model is
focused also on applying lean tools to maintenance
as an effective way to promote these synergies,
which is achieved by integrating Lean
manufacturing and maintenance together. To this
end, the concepts of lean, maintenance and
reliability improvement was addressed
simultaneously, in order to maximize the asset
performance as the financial value generated by
organization’s facilities. to optimize the asset
performance and equipment effectiveness in the
model as a further step towards world class
maintenance: process stabilization, reduction of
inventory buffers and application of Lean
manufacturing tools in a maintenance process
Process stability
Unpredictable processes and/or high degree of
downtime variance usually lead to inconsistency
between cycle times of production units and time
taken (that is the maximum time per unit allowed to
produce a product in order to meet demand). This
situation usually disturbs the balance of buffers,
increases the waiting times between each stage of
the process and most importantly, raises the need of
investing on capital assets in order to cope with peak
capacity requirements. Hence, by stabilizing of
production process, an organization can benefit from
shorter cycle time, smaller buffers and higher
equipment effectiveness.
Inventory buffers
So far, inventory buffers have not been
considered as a maintenance and reliability
improvement issue. But it must be considered that
performing effective maintenance practices to
enhance the reliability of production process can
directly influence the amount of raw, WIP and
finished inventory buffers (Finigan and Humphries,
2006). With application of lean tools and techniques
in maintenance process three improvement
opportunities will be achieved: (1) The buffers can
be reduced due to high reliability of production
units; (2) With a smaller buffer, the WIP parts spend
less time in the buffers and as a result the processing
time in each work station will be decreased, while in
total, this reduction of lead time for each customer
order, can provide a significant competitive
advantage for the organization; (3) Smaller buffers
can also reduce the probability of producing large
amounts of defects prior to discovery at the next
workstation due to many WIP in a buffer. Therefore,
the costs of scrap and rework as two of the major
manufacturing overhead costs can be substantially
reduced.
Lean tools
In addition, application of five lean
manufacturing tools which are embedded in the
model has great compatibility with manufacturing
operations as well. Hence, they can optimize both
maintenance and manufacturing processes
simultaneously. In general, these tools can be
naturally fitted to every practice within an
organization that wants to promote to Leanness.
These tools include visual control, 5S, seven wastes,
Single Minute Exchange of Dies (SMED) and Poka-
Yoke (Doing things right First Time).
IV. FROM MANUFACTURING
EXCELLENCE TO WCM
Reaching to world class maintenance by
integration of TPM, six-sigma and lean tools and
techniques, predispose the development of world
class manufacturing as ultimate objective. All too
often, many advanced manufacturing technologies
and techniques are deployed before deep analysis of
the needs of the company owing to evolving
prevalent misconception which for achieving world
class standards, application of advanced
technologies or high degree of automation are
inevitable. However, without clear understanding of
problems and barriers on the way of ultimate goals
and also without clarifying the potential gap between
current and desired future state of the company,
superficial adaption of technological solutions may
result in poor return of investment and other
unfavorable results. Moreover, the process of
adaptation must consider the size and skills available
in various levels of the company. Today, many
SMEs are among the topnotched companies, not
because of implementing modern manufacturing
facilities but due to having skillful employees,
unique product features aimed at satisfying specific
market needs, price range and flexible business
strategies. In this regard, the model is extended to
include a key strategy that when applied alongside
Value Stream Mapping (VSM), Quality Function
Deployment (QFD) and other value identification
methodologies, can help to identify the gap between
current and future state of organization, through
measuring performance against world class
standards. To this end, tools and methodologies of
quality, lean and six-sigma is applied again in order
to develop a pipeline of specific projects that will
help to close the identified current and future gap.
The main role of lean philosophy in this stage of an
integrated improvement program is creating the
basis and a foundation for improvement. In this way,
6. R Nesamoorthy. Int. Journal of Engineering Research and Application www.ijera.com
ISSN : 2248-9622, Vol. 7, Issue 5, ( Part -2) May 2017, pp.01-10
www.ijera.com DOI: 10.9790/9622-0705020110 6|P a g e
the lean concept removes the dust of ambiguities
from hidden costs and hidden non value-added
activities, helping to reveal a realistic view of
current state of organization which allows Six-Sigma
to fill the business gaps faster and in a more efficient
manner in subsequent steps. From another point of
view, since some of the lean improvements occur
virtually immediately compared to entire
improvement project, observing the results of Lean
projects can keep alive the momentum and
motivation of employees to continue.. At the first
step, lean introduces VSM as the central tool to
develop a current state map which gives a holistic
yet detailed look at the processes in the company
which is essentially a snap shot capturing how things
are currently being done. Analytical study of the
current state map can disclose the weaknesses
strengths in production flow from raw materials
target product or service to the customers and driven
towards the world class state.
Subsequently, the scope and boundaries of
improvement should be defined by identifying the
WCM criteria for specific industry in which the
company with specific size and skill is operating. In
fact, due to substantial increase in advanced
manufacturing techniques, the only way to control
the complexity and economic feasibility of the
model is framing these advanced tools and
techniques based on the needs of the company.
Benchmarking of determinant features of current
position such as business strategy, technology
capabilities, work force skills and market share
besides simplicity and sequential nature, the
feedback- based nature of the process is particularly
important to the company, which is essentially a
snapshot capturing the company. By applying
iterative process, management how things are
currently being done can assess the suitability of
potential solutions and any changes that have made
in the process. Moreover, the model deploys seven
key performance indicators information to delivery
of (KPI) under quality, cost and delivery (QCD)
metrics as suggested by UK Department of Trade
and Industry (2004). The main reasons for choosing
this specific metrics are high capability in
simplifying the complex manufacturing process,
providing rapid feedback and streamlining the
process of benchmarking by providing a quantifiable
numeric comparison. Table 3 outlines seven key
measures and their potential impact on quality, cost
and delivery. Each of these measures uses simple
mathematical equation to analyze the performance of
manufacturing system and provides results that can
be used as the basis of continuous improvement.
Model Verification
Organization and by performing a series of
activities; it continually improves towards WCM as
ultimate objective. In many traditional organizations,
the success of each department is measured
independently and integration of each department
with other departments ends where the boundaries of
their respective responsibilities meet (Ross, 1991).
Thus they need major alignment and critical
infrastructures to become prepared for adoption of
WCM concept. The new model emphasizes on full
integration of all departments of organization,
especially maintenance and manufacturing
departments. Indeed without reaching to excellence
in the maintenance process, struggling for WCM
will be diminished to failure. Therefore, adaptation
of this culture and values has conceptually
embedded in the model. Moreover, successful
application of WCM methodology requires roles and
knowledge which may not be founded in the old
organizations. So the concept of management
commitment to the implementation of on-going
training and skills improvement opportunities for
employees is another underlying alignment for
WCM, which is considered in the model.
Furthermore, WCM requires a new operating culture
which is related to elimination of wastes,
identification of value-added manufacturing
activities, reducing costs and commitment to quality.
These issues are fundamental principles of WCM
which are attained by placing Lean thinking as a
pivotal concept in preparing both maintenance and
manufacturing functions to promote to world class
standards.
Potential benefits of many WCM models
cannot be achieved due to forcing the users to
implement many tools and techniques in the way of
WCM. Excessive and unjustifiable use of tools
intensifies the complexity of the model and
necessitates consuming most of the resources of the
company such as time, personnel, machines, etc.,
without considerable progress towards main
objectives, which most of the times cause
disappointment and frustration of the executives and
employees and made them reluctant to continue.
Keeping this fact in mind, the new model focuses on
the implementation of TPM, Six-Sigma, TPM and
Lean as three central tools, while other supporting
tools can be applied to increase the efficiency of the
process on an as-needed basis. The sequence and
method of implementing these central tools have
addressed precisely. For each phase of the change
process, a detailed, step-by-step road map has been
provided to help companies in the journey toward
implementing and sustaining the model (Okhovat,
2010). Moreover, following a systematic procedure
can result in a better understanding, direction and/or
commitment and motivation from management. In
parallel with implementation of three key
components of the model, specific yet most effective
tools from an advanced toolbox of quality
7. R Nesamoorthy. Int. Journal of Engineering Research and Application www.ijera.com

management, six-sigma and lean, related to each
phase is recommended in order to help users to
achieve maximum outcomes and avoids them from
the trial and error approach. In the way of reaching
to WCM, defining right metrics to measure
performance play a vital role. Simply put, only when
right questions are asked, right answers can be found
(Basu and Wright, 1996). Many performance
measures have been suggested by different
researchers in order to monitor and assess the
achievements of the improvement process. By
reviewing current models, it was noticed that almost
all of them have used very general terms to measure
the process which in turn may seem idealistic and
unable to motivate both managers and employees of
those organizations that initially started the journey
towards WCM. Therefore, the proposed model has
tried to cover this issue by developing an internal
benchmarking approach that enables an organization
to self-appraise against established WCM standards.
In this regard, the model concentrates on quality,
cost and delivery (QCD) outputs, which are seven
quantitative measures as suggested by British
Department of Trade and Industry (2004) (Table 3),
and can be readily calculated, plotted and analyzed
in a constant manner to provide rapid feedback to
assess the results of any changes made in the
production process. This can be effective to motivate
the executives in placing more commitment to
implementing the model by observing performance
improvement trend. In addition, QCD measures can
simplify a complex production process to establish a
straightforward route for continual improvements.
Benefits of New Model
1) Establishing a structure for efforts of
implementing manufacturing excellence.
2) All the advantages of TPM, lean and six-sigma
are kept in tact in the model. These advantages
are just integrated and systemized in order to
reach world-class status.
3) Application of the new model can develop a
culture of continuous improvement through re-
evaluation of appropriate performance measures
both in the maintenance and manufacturing
process. So, with every iteration of the model, a
further step towards reaching WCM can be
taken.
4) Coherent synthesis of six-sigma, TPM and lean
by using structured DMAIC technique, can
facilitate joint implementation of these systems
in order to excel both maintenance and
manufacturing process in parallel.
5) Aligning the cultural aspects of lean with the
data driven and project-focused investigations
of six-sigma and operator empower rment of
TPM, can bring high potential for a
comprehensive and sustainable approach to
organizational change and process
improvement.
6) The methodology of new model can promote
the culture of team work and problem solving,
which ensure high quality of outcomes.
7) Analogous to traditional manufacturing which is
revolutionized by lean concepts, maintenance as
a peopledriven function, can be transformed to a
predictive and proactive system that provides a
reliable process through lean philosophy.
Hence, adapting and applying lean
manufacturing techniques in maintenance
functions enhances the synergistic effects of
integrating maintenance excellence and world-
class manufacturing. Moreover, linking
maintenance improvements to buffer challenges
provides massive gains through leadtime
reduction, increasing asset performance and
profitability, as well as reducing manufacturing
costs as a result of performance improvement.
8) The culture of breaking down the internal
barriers between maintenance and
manufacturing departments has been
conceptually embedded in the model. This
culture and values create partnership and
authority, which in turn provides required
alignment and critical infrastructures to become
prepared for adoption of WCM concept.
Application of New Model:
Manufacturing industries that either
initially wants to start their journey towards WCM
or those that are at the middle of journey. The
developed model can also coherently fit to
improvement strategies of organizations that are
trying to reach excellence and wish to excel in
global scenario. It is believed that this model will
reinforce the strategic decisions which have to be
made by managers. Specific and new to this model is
that, unlike most of the current models that are
developed mainly in relation to the needs of larger
scale organizations, the proposed model can be
regardless of level of skills and size of the company.
Given adequate flexibility enables each company to
apply and customize the scope of the model based
on its requirement, extent of limitations and desired
organizational goals.
V. CONCLUSION
Since achieving world-class is a moving
target, the quest for reaching to such status is not a
destination but an ongoing journey that creates more
and more improvement opportunities over time. The
authors believe that with a minimum combination of
strategic concepts (that is - lean, six-sigma and
TPM), remarkable level of performance can be
achieved in both maintenance and manufacturing
arenas. It is remarkable that implementation of the
model should be based on an integrated fashion

rather than a sequential manner, since effective
application of each tool is embedded at the heart of
other concepts, and also methodology of all tools has
spread over every phase of model implementation.
This method highlights the significance of reaching
to maintenance excellence as an inseparable pre-
stipulation for progressing towards WCM. It must be
mentioned that in general, the improvement
achieved by implementing the WCM model will
take time; one cannot become world-class in all
functions overnight. However, genuine commitment
and direct involvement of management, followed by
the education and empowerment of the employee as
strong foundation, can catalyze the change process,
yet maximize its effectiveness. The proposed
integrated WCM model can be applied in real
environmental conditions to test the validity and
reliability of the model with proven examples and
data. This can be considered as one of the limitations
of this study. Hence, it is beneficial to apply the
model in different scenarios to understand the
effective use of this model by the use of experiments
in the real world, or empirically validate and refine
the suggestions of the model through a questionnaire
survey. The systematic approach presented by Flynn
et al. (1990) could be applied to conduct an
empirical investigation of WCM across a wide range
of manufacturing companies in different industrial
sectors with respect to the proposed model. Planning
for the questionnaire survey, it should be noted that
although obtaining questionnaire data are relatively
easy (because of their nature), however, there is
difficulty when it comes to vagueness of the
obtained analysis. Therefore, the pilot questionnaire
and data should try to reduce vagueness of the
survey in every step from designing of the
questionnaire to analyzing the data.
