Authors:

Abstract

Failure mode and effects analysis (FMEA) is a risk assessment tool that mitigates potential failures in systems, processes, designs, or services and has been used in a wide range of industries. The conventional risk priority number (RPN) method has been criticized for having many shortcomings. Various risk priority models have been proposed in various literature to improve the performance of the FMEA itself. However, there has been no literature review on this topic. This study reviewed 50 FMEA papers published between 1998 and 2019 in international journals and categorized them according to various industry and industry output. The automotive and manufacturing industries dominated the implementation of FMEA. For the industry's production: goods and services, mostly dominated by interests in implementing FMEA in their industries. Hopefully, this finding will be useful for goods and services industries willing to implement FMEA, especially the services industry.

Failure mode and effects analysis (FMEA) is a risk
assessment tool that mitigates potential failures in systems,
processes, designs, or services and has been used in a wide
range of industries. The conventional risk priority number
(RPN) method has been criticized for having many
shortcomings. Various risk priority models have been
proposed in various literature to improve the performance of
the FMEA itself. However, there has been no literature
review on this topic. This study reviewed 50 FMEA papers
published between 1998 and 2019 in international journals
and categorized them according to various industry and
industry output. The automotive and manufacturing
industries dominated the implementation of FMEA. For the
industry's production: goods and services, mostly dominated
by interests in implementing FMEA in their industries.
Hopefully, this finding will be useful for goods and services
industries willing to implement FMEA, especially the

1. INTRODUCTION
Failure mode and effects analysis (FMEA), first
developed as a formal design methodology in the
1960s by the aerospace industry, has proven to be
a useful and powerful tool in assessing potential
failures and preventing them from occurring.
FMEA is a technique to analyze, identify,
determine, and eliminate a known failure,
problem, or error with the potential of a system,
design, process, or service before they reach the
customer. The primary purpose of FMEA is to
identify potential failure modes, evaluate the
causes of failure and the effects of various
component failures. The analysis results can help
analysts identify and correct the failure modes that
have a detrimental effect on the system and
improve its performance during the stages of
design and production. And FMEA has been
widely used in various industries, including
aerospace, automotive, nuclear, electronics,
chemical, mechanical, food and beverage,
education, construction, medical technology, and
other industries. It is frequently observed that
productivity is related to guidelines for
productivity improvements achieved through
strategic planning (Gold, 1985). As a sector that
contributes to more than 50% of Gross Domestic
Product (GDP) in the global economy, the service

sector's importance will grow in the future (Gecky
et al., 2010). Currently, most FMEA is used for
industrial production that produces the goods, and
not much services industry using FMEA method.
2. LITERATURE REVIEW
FMEA is an important technique used to identify
and eliminate known failures or have the potential
to improve the reliability and security of complex
systems and is intended to provide critical
information for making decisions in risk
management. To analyze a specific product or
system, a cross-functional team should be
established for carrying out FMEA first. The first
step in FMEA is to identify all possible potential
failure modes of the product or system by a session
of systematic brainstorming. After that, critical
analysis is performed on these failure modes
taking into account the risk factors: occurrence
(O), severity (S), and detection (D). The purpose
of FMEA is to prioritize the failure modes of the
product or system to assign limited resources to
the most serious risk items. In general, the
prioritization of failure modes for corrective
actions is determined through the risk priority
number (RPN), which is obtained by finding the
multiplication of the O, S, and D of a failure. That
is: RPN = O x S x D. FMEA is a structured
technique that can help in identifying all failure
modes within a system, assessing their impact, and
planning for corrective actions, and to extend the
application of FMEA to risk management in the
construction industry (Abdelgawad & Fayek,
2010). In FMEA, component failures are linked to
risk events, while each failure can become the
object of detailed failure analysis and corrective
action planning (Aboutaleb et al., 2019). Due to
innovation in implementing and managing
projects, effective use of Failure Modes and
Effects Analysis (FMEA) technique has been
proposed (Bahrami et al., 2012). FMEA aims to
delight and satisfies the customer by preventing
failures that may occur at all levels from product
conception to its completion for delivery to ensure
improved quality and reliability of product
delivered in time for the user (Belu et al. 2013).
3. RESEARCH METHOD
This research aims to explore deeper into FMEA
implementation in various industries. The study
was carried out using the goals in mind. The terms'
FMEA' and 'Implementation in Industries' were
used to search for articles. The range of journals
published for this research from year 1998 to
2019.
This research was conducted by reviewing
80 papers found using FMEA. However, 30
journals did not meet the requirements and aspects
discussed. So it can be concluded that there are
only 50 journals left in accordance with this
discussion. So the data used in the journal is data
that has been implemented correctly in their
respective industries.
In this study, the author reviewed several
international journals, all of which were related to
the implementation of FMEA. The review in this
study is based on two aspects: (1) goods output;
(2) services output (Fig. 1).

4. RESULT AND DISCUSSION
The 50 journals of FMEA implementation in
various industries were selected for review (Table
1). The selected journals or articles were analyzed
from the aspect of FMEA methodologies, consist
of FMEA basic concepts and FMEA
enhancement, then also analyzed by research
object and the result for following review of
selected articles.

4.1. Type of Industries
At the previous Table 1. Above, showing the most
dominant implementation FMEA mostly in the
manufacture and automotive industries. Of 50
papers collected in table 1, above mentioned 11
papers are discussions about the implementation
of FMEA in manufacturing industries, and ten
papers also talk about the implementation of
FMEA in automotive industries. The classification
articles based on the implementation of FMEA in
various industries can see in Fig.2 below.
Fig. 2. Implementation FMEA in various
industries.
The advantages of FMEA have resulted in its
implementation into nearly every branch of
modern industry, both for unitary and mass
production and the example of application of
FMEA in mass production is a production process
of beverage cans (Rękas et al. 2014). Failure mode
and effect analysis (FMEA) is methodologies that
facilitate process improvement and manufacturing
capabilities ( Puvanasvaran & Jamibollah 2014).
The classification based on percentage of
implementation FMEA in various industries we
can see at Fig.3 as below.
Fig. 3. Percentage implementation FMEA in
various industries.
From the fig.3 above, it is showing that the
percentage of comparison each industries in
implementing FMEA, founded the big 3 are
manufacture dominated 22% with the first rank,
next the second rank is by automotive industries
with 20% and the third is by food and beverage
with 5% of implementing FMEA. This
phenomenon indicated that most industries that
produce goods implementing FMEA to assess the
potential failure and improve, so the Severity,
Occurrence, Detection, and RPN will be reduced.
FMEA helps the SPC implementation either in
process selection or output analysis. Also, this
integration has been applied in a car battery
industry that is less-developed (Khorshidi et al.,
2013). FMEA method (Failure Modes and Effects
Analysis), which is widely used in the motor
vehicles industry (Popović et al. 2010).

4.2 Year of Publication
The distribution of final samples per year of
publishing is shown in Figure 4. Some articles
published online that have been included in this
review can be seen from the following Fig. 4.
Fig. 4. Year of publication
From the data collected above, most researchers
publish the article for implementation FMEA in
the industry in year 2014, then followed in 2013.
This also indicated that in those years, the
researcher found some industrial problems that
have been solved using FMEA.
4.3 Industries Output
Fig. 5. is the result of a journal review that has
implemented FMEA of industries output. From 50
journals, showed 90% (around 45 journals) the
output produce is goods and the rest only 5%
showing the output produce is services.
Fig. 5. Goods and services output produce in
implementing FMEA
4.4 Research Challenge in Implementing of
FMEA in Industries produces output
For service industries, providing error-free
services is even more challenging because their
intangible nature renders subjective perceptions of
quality. Equally troublesome is the uncontrollable
element of customer participation in the service
process because production and consumption
occur as simultaneous processes. Despite these
challenges, however, service quality and customer
satisfaction are closely related constructs. When
service providers continuously strive to develop
error-free strategies, customer satisfaction is sure
to follow. And what potential rewards can FMEA
provide? Does the Service Company that will
conduct FMEA experience the following:
a. Minimized customer defection or increased
customer satisfaction?
b. Increased consistency in service quality?
c. Reduction of costly design changes?
d. Reduced transaction costs/increased profits?
e. Reduced reliability?
5. CONCLUSION
Although many endeavors have been dedicated to
utilizing FMEA in various industries sectors,
driven by the challenges in modern business and
the escalation of global disastrous events, the
implementation of FMEA in services sector gaps
is still left for future study. As this study is merely
based on limited literature, we encourage future
research to extend our initial survey using more
databases and incorporating other references such
as book chapters, dissertations, and literature.
Moreover, we also suggest that other researchers
to widen the discussion on the role of FMEA in
enhancing six sigma-oriented service systems and
its role in creating value within a collaborative
business framework.

The complex nature of operations in the oil and gas sector makes it highly exposed to risks that might impact its overall performance. Maintaining the industry's competitive edge and ensuring the efficiency of supply chain operations requires proper risk identification and management. This paper focuses on the study of the risks associated with the oil and gas supply chain in Oman. This study uses the Failure Mode and Effects Analysis (FMEA) approach to evaluate the risks associated with several stages of the supply chain in Oman's oil and gas sector, such as exploration, drilling, production, transportation, storage, refinement, and distribution. As a structured methodology for mitigating risks and improving supply chain reliability, FMEA systematically identifies and prioritizes potential failure modes. To do this, interviews were conducted with four experts from two distinct Omani-based oil and gas companies, utilizing their knowledge and experience with supply chain operations and associated risks. According to the results obtained, drilling and transportation emerge as the riskiest activity in the Omani oil and gas supply chain, while exploration is rated the least risky. This study advances the knowledge of supply chain risk management in the oil and gas sector by demonstrating the effectiveness of the FMEA technique for detecting and mitigating supply chain hazards. The study's findings are important for supply chain managers and industry experts in Oman's oil and gas industry, as they can help improve risk mitigation approaches and overall supply chain efficiency.

PT. XYZ is a company that produces plywood. The issue faced by this company is the increasing risk of defective plywood products resulting from the production process. This research conducts a risk analysis of rejected defective products using the Statistical Process Control (SPC) method to identify the types of defects and their causes, as well as the Failure Mode and Effect Analysis (FMEA). Based on production data from January 2022 to April 2023, PT. XYZ Samarinda has produced 6,629,815 plywood pieces, with 356,137 rejected defective products. There are 10 types of defects, namely delamination defects, blisters, 2x process fractures, impacts, cores that are too narrow, patches, defective sander F/B, F/B too narrow, defective press F/B, and uneven cores. The results obtained from the SPC method indicate that there are four priority defect types: delamination defects, blisters, 2x process fractures, and impacts. According to the FMEA method, the most risky cause for delamination defects is applying a layer of adhesive that is too thin, with an RPN value of 280. The most risky cause for blister defects is an excessively high adhesive dose, with an RPN value of 180. The most risky cause for 2x process fractures is excessive pressure during the core scratching process that penetrates the F/B, with an RPN value of 210. The most risky cause for impact defects is careless workers when moving plywood lots using a cart, with an RPN value of 144. Subsequently, improvement proposals are made using the 5W+1H method to determine the causes of defects and the necessary improvements that the company should undertake.
... FMEA is a structured method used to identify, determine, and prevent all forms of failure (failure modes) that cause problems, errors, etc. that change the function of the product or design [15]. Risk Priority Number (RPN) is a technique for analyzing risks related to potential problems that have been identified during FMEA creation to determine appropriate corrective actions according to the failure mode [16]. RPN is used in the FMEA procedure using three criteria Severity (S), Occurrence (O), and Detection (D). ...

PT. XYZ is a leading manufacturing company that focuses on the textile industry, especially in producing yarn from cotton, polyester, and rayon raw materials. Even though it has adequate infrastructure and machines, the performance of the Winding machines at PT. XYZ is not yet optimal, characterized by machine downtime problems and defective products. This research aims to identify and analyze the performance of Winding machines to find the root of the problem and formulate the necessary follow-up actions. The analysis method used is Overall Equipment Effectiveness (OEE) which includes three main aspects: Availability, Performance Rate, and Quality Rate. International standards set optimal values for OEE, where Availability Ratio > 90%, Performance Rate > 95%, Quality Rate > 99%, and OEE > 85.4%. The research results show that although the average Availability Ratio reaches 90.5%, the Performance Rate and Quality Rate are still below international standards. Improvements in Performance Rate and Quality Rate are needed to meet international standards and increase production efficiency. The average OEE value is 77.1%, therefore improvements are needed in the Performance Ratio and Quality Rate to meet international standards. Among the factors causing Six Big Losses, three main causes contribute to losses, namely: Equipment Failure (Breakdown Losses) of 11.7%, Process Defect Losses of 7.34%, and Reduce Yield Losses of 64.6%. Of these three main causes, reduced yield Losses have the largest impact with a percentage of 64.6%, which is caused by machine instability due to improper handling by maintenance operators. Through the application of the Failure Mode Effect and Analysis (FMEA) method, it was found that bearings that experienced cracks were the most influential cause of failure with a Risk Priority Number (RPN) value reaching 60. This problem is caused by the production operator’s lack of concern regarding machine damage, delays in reporting to maintenance officers, errors in installing spare parts, poor maintenance control, and insufficient compressor air pressure. Therefore, the main improvements that need to be made to increase the productivity of Winding machines at PT. XYZ is in the areas of Equipment Failure (Breakdown Losses), Process Defect Losses, and Reduce Yield.
... Based on evaluation criteria such as the risk, occurrence, and detection, a value from 1 to 10 is assigned (where 1 represents minimal risk, low impact, or high detectability), and then, all values are multiplied to obtain the RPN index value. The resulting value helps determine which problems should be prioritized, helping organizations more effectively identify areas for improvement [28][29][30]. ...

This article discusses the subject of the environmental assessment of products based on specific methods (LCA, ReCiPe, and SM2013) and tools (GaBi, SimaPro, and Sustainable Minds). The aim of this work was to analyze selected IT tools for supporting such an assessment. Assumptions and criteria were adopted, based on which specific IT tools were selected for a comparative analysis. Then, an environmental assessment of reference products was carried out using three different IT tools. The structure of the products was prepared in such a way that the parts and subassemblies met two basic requirements. First, they were made of construction materials that are generally available and used in industry. The second requirement was that the technologies for manufacturing these parts included as many frequently used technological processes as possible. This allowed for a comparison of the results of estimated environmental assessments generated by selected IT tools. As a result, the strengths and weaknesses of each of the IT tools were identified.

PT Wijaya Karya (Persero) Tbk, a leading state-owned construction enterprise, faces significant waste management challenges that have caused financial losses in previous projects. This study applies lean construction and risk management to identify waste and risks in the Jragung Dam Construction Project Package 2. Waste identification began with brainstorming sessions with the project management team, followed by a borda questionnaire to prioritize waste using the pareto principle. 5-whys discussions were then used to determine the risks causing critical waste. These risks were categorized using the Risk Breakdown Structure (RBS) and analysed through Failure Mode and Effect Analysis (FMEA), with risks plotted on a cartesian diagram based on Risk Priority Number (RPN) and Risk Severity Value (RSV). The four critical waste types identified were defects (20.05%), waiting (19.80%), over-processing (17.79%), and overproduction (14.04%). The highest-priority risks were unfinished diversion channels (RPN 108, RSV 36), geological issues found (RPN 105, RSV 35), and design revision (RPN 96, RSV 32). The benefit of this research is a systematic approach for identifying waste through lean construction and risk management principles, facilitating targeted waste identification. This process is expected to help the company make informed decisions, enhancing project efficiency and reducing potential financial losses.
