| Title: Reducing Inpatient Suicide Risk: Using Human
Factors Analysis to Improve Observation Practices |

THE LAW, 37 (1): 15-24 2009 |

| Abstract: In 1995, the joint Commission began requiring
that hospitals report reviewable sentinel events as a condition of
maintaining accreditation. Since then, inpatient suicide has been
the second most common sentinel event reported to the joint
Commission. The joint Commission emphasizes the need for
around-the-clock observation for inpatients assessed as at high risk
for suicide. However, there is sparse literature on the observation
of psychiatric patients and no systematic studies or recommendations
for best practices. Medical errors can best be reduced by focusing
on systems improvements rather than individual provider mistakes.
The author describes how failure modes and effects analysis (FMEA)
was used proactively by an inpatient psychiatric treatment team to
improve psychiatric observation practices by identifying and
correcting potential observation process failures. Collection and
implementation of observation risk reduction strategies across
health care systems is needed to identify best practices and to
reduce inpatient suicides. |

| Abstract: Digitalization of not only non-safety but also
safety-grade I &C systems With full computerized Main Control ROOM
(MCR) is the recent trend of I&C systems Of nuclear power plants
(NPP) around the world, while plant maintenance has been shifting
From traditional time based maintenance to condition based
maintenance. In order to cope with the new trend of operation and
maintenance in NPP, a concept of online distributed diagnostic
system for both plant operation and maintenance has been proposed in
order to Further improve both the plant efficiency and file work
environment of plant operation staff members by organizational
learning. In this respect., the research subjects Of human machine
interface (HMI) for the online distributed diagnostic system are
also discussed for supporting the plant personnel at both MCR and
local working places in the plant by the application of advanced ICT
(Information and Communication Technologies). |

| Abstract: An assessment model is usually a mathematical
model that produces a measuring index, in the form of a numerical
score to a situation/object, with respect to the subject of measure.
To allow a valid and useful comparison among various
situations/objects according to their associated numerical scores to
be made, two important properties, i.e., the monotone output
property and output resolution property, are essential in fuzzy
inference-based assessment problems. In this paper, the conditions
for a fuzzy assessment model to fulfill the monotone output property
is investigated using a derivative approach. A guideline on how the
input membership functions should be timed is also provided.
Besides, the output resolution property is defined as the derivative
of the output of the assessment model with respect to the input,
whereby the derivative should be greater than a minimum resolution.
Based on the derivative, improvements to the output resolution
property by refining the fuzzy production rules are suggested. A
case study on the Bowles fuzzy RPN model to demonstrate the
effectiveness of the properties is also included. |

| Title: EXAMPLE FOR MOBILE ECG HOLTER DESIGN USING FMEA
MODEL |
| Source: BIOMEDICAL ENGINEERING-APPLICATIONS BASIS
COMMUNICATIONS, 21 (1): 61-70 FEB 2009 |
| Abstract: This paper describes an approach for evaluating
the risk of components used in the Holter. Holter is a portable
device for recording patients' electrocardiogram in medicine. Holter
might hurt users as a result of a bad design, and might record
incorrectly when malfunction happens. To prevent risk of injury, we
analyze the potential failures of the Holter based on the Failure
Mode and Effects Analysis, which is a risk assessment technique.
Then, we calculate the Risk Priority Number (RPN) of each failure.
According to the RPN, we give two strategies for reducing the risk.
One is protection, and the other is alarm. The protection system is
used to prevent hazards of the Holter from incorrect operations by
the user, and the alarm system is used to detect the malfunction of
the Holter. The experimental results show that the safety of the
Holter is improved with these two circuits. |

and cause and effect analysis on processing of ready to eat
vegetables - part II |
| Source: INTERNATIONAL JOURNAL OF FOOD SCIENCE AND
TECHNOLOGY, 44 (5): 932-939 MAY 2009 |
| Abstract: Failure mode and effect analysis (FMEA) model
has been applied for the risk assessment of ready to eat vegetables
manufacturing. A tentative approach of FMEA application to the ready
to eat vegetables industry was attempted in conjunction with cause
and effect diagrams. critical control points have been identified
and implemented in the cause and effect diagram (also known as
Ishikawa, tree diagram and fishbone diagram). The main emphasis was
put on the quantification of risk assessment by determining the risk
priority number (RPN) per identified processing hazard. Receiving,
storage and distribution, packaging and cooling were the processes
identified as the ones with the highest RPN (225, 225, 180 and 144
respectively) and corrective actions were undertaken. Following the
application of corrective actions, a second calculation of RPN
values was carried out leading to considerably lower values (below
the upper acceptable limit of 130). It is noteworthy that the
application of Ishikawa (cause and effect or tree diagram) led to
converging results thus corroborating the validity of conclusions
derived from risk assessment and FMEA. Therefore, the incorporation
of FMEA and cause and effect analysis within the ISO22000 system of
a ready to eat vegetables processing industry is considered
imperative. |

| Title: Hazard assessment for the safe storage,
manufacturing and handling of flash compositions |
| Source: JOURNAL OF LOSS PREVENTION IN THE PROCESS
INDUSTRIES, 22 (2): 254-256 MAR 2009 |
| Abstract: Fireworks manufacturing in India is generally
carried out manually due to sensitive nature of the chemical
mixtures to thermal, mechanical and electrical hazards. Despite
extreme care accidents continue to record leading to fatalities and
complete destruction of the facility. Since there are no piping and
instrumentation diagrams, it becomes difficult to apply the
conventional hazard assessment techniques like HAZOP, FTA, and FMEA.
In this work, for the first time one of the well-known hazard
identification procedures called "what-if analysis" was used to
identify hazards in a typical firework manufacturing facility. Such
methodical analysis helped to identify conditions that can lead to
an accident situation. This paper discusses many necessary safety
precautions to be followed in the manufacture of flash compositions.

Abstract: To reduce development costs and time,
automobile manufacturers intend to limit the number of
cost-intensive and time-consuming prototypes to verify the
functional characteristics of the vehicles. Hence, verifications
based on experimental testing in former times shall be replaced
today by numerical simulations. To stay abreast of these changes and
to account for rising complexity in modelling and methods, there is
the need of accurately defined and quality controlled practices and
processes for numerical analysis and simulation. The results of
corresponding initiatives are presented here.
Within the scope of an ongoing research project, methods known for
quantifying the quality used in design engineering, production and
experimental testing were adapted systematically - if appropriate -
to numerical simulations for the functional design of car bodies. In
particular, a procedure model was developed for managing the quality
of the product as well as the process of numerical analyses and
simulations. The proprietary procedure model is based on a
combination of "Quality Function Deployment" (QFD) and "Failure Mode
and Effects Analysis" (FMEA), which is already approved in several
other scopes. The successful transfer to virtual design is shown
here. |

| Title: The Risk Assessment and Management of Port
Security Using Fuzzy Modeling |
| Source: MARINE TECHNOLOGY AND SNAME NEWS, 46 (2): 61-73
APR 2009 |
| Abstract: A security assessment is considered to be a
difficult mission because of the characteristically unpredictable
outcomes associated with high consequences. This study offers an
illustration using different approaches both in thinking about and
in dealing with this issue. The security risk can be modeled and a
risk ranking can be obtained based on the concept of "Failure Mode,
Effects, and Criticality Analysis" (FMECA) using a fuzzy rule base
method. The model presented in this study is based on the assumption
that the elements of criticality at each port facility, and of the
vulnerability of the security measures associated, are more
important than the elements of probability of occurrence the threat
associated and also of its severity. This is because the former two
elements are the only factors that can be fully under control by the
port authority. The priority of the order in implementing the
modified security measures proposed to enhance the security level of
each scenario is determined using "Expanded Failure Mode and Effects
Analysis" (EFMEA), taking into account their feasibility and effect. |

| Abstract: Electric power industry deregulation has
brought about the unbundling of generation, transmission and
distribution services and as such, new techniques for reliability
assessment are being developed to account for the consequent
structural changes in the restructured environment through direct
analytical techniques or stochastic simulation. To this end,
reliability equivalent techniques have been proposed in recent
literature and are continuously being improvised upon, especially
for the multi-bilateral contracts market structure. Power flow
tracing, a potential tool that has so far only been effectively
employed in transmission pricing in the open access environment, is
deemed to be equally effective in capturing the effect of structural
and economic alterations for the purpose of reliability evaluation
in the liberalized regime. This paper elaborates on the idea that
when used in tandem with reliability equivalent methods, tracing is
bound to improve the accuracy of the indices in vogue. The
contribution of individual generators and loads to tine flows is
obtained using a graph theoretic approach, relying on the
proportional sharing principle. This information is then proposed to
be used in the transmission line Failure Modes and Effects Analysis
(FMEA) phase of the established procedure of reliability network
equivalents. Comparisons are drawn to highlight the computational as
well as accuracy benefits accrued in doing so. |

process and the theory of lose control of energy releasing, an
investigation on identification, analysis and control of hazard
sources in the process system of preparing coal, coking, reclaiming,
maintaining and dynamics in a coking plant has been carried out.
Many analysis methods, such as Preliminary Hazard Analysis (PHA),
Failure Modes Effects Analysis (FMEA), Fault Tree Analysis (FTA)and
Hazard And Operability Studies (HAZOP) have been used. In the hazard
units, index of hazard frequency and degree of hazard severity have
been calculated. Hazard source management grades have also been
confirmed. Based on the identification and analysis results, the
hazard control measures in a coking production process have been
brought forward. |

analysis based on polychromatic sets |
| Source: AI EDAM-ARTIFICIAL INTELLIGENCE FOR ENGINEERING
DESIGN ANALYSIS AND MANUFACTURING, 23 (2): 119-129 MAY 2009 |
| Abstract: Traditional failure modes and effects analysis
(FMEA) methods lack Sufficient semantics and structure to provide
full traceability between the failure modes and the effects of the
complex system. To overcome this limitation, this paper proposes a
formal failure knowledge representation model combined with the
Structural decomposition of the complex system, The model defines
the failure modes as the inherent properties of the physical
entities Lit different hierarchical levels, and employs the
individual color. unified color. and Boolean matrix of the
polychromatic sets to represent the failure modes in terms of their
interrelationships and their relations to the physical system. This
method is a structure-based modeling technique that provides a
simple. yet comprehensive framework to organize the failure modes
and their causes and effects More systematically and completely.
Using the iterative search process operated oil the reasoning
matrices. the end effects on the entire system call be achieved
automatically. which allows for the consideration of both the single
and multiple failures. Ail example is embedded in the description of
the methodology for better understanding. Because of the powerful
mathematical modeling capability of the polychromatic sets. the
approach presented in this paper makes significant progress in FMEA
formalization. |

| Abstract: Classical risk assessment and risk management
which is gaining importance in many industries is usually based on
well defined processes and uses techniques like FTA and FMEA.
However, classical risk analysis techniques like FTA and FMEA should
ideally be automated, at least to some extent and without loss of
effectiveness, to enable fast and cost effective iterations of
system modelling and risk analysis that can meet the tight cost and
time constraints of most offshore projects. This paper is focused on
the presentation of a new concept and tool extension for model-based
synthesis of fault trees and FMEAs in which these failure analyses
are automatically constructed from engineering design models, e.g.
simulation models that have been augmented with information about
the local propagation of failures. The simulation model is developed
in the commercial system modelling tool SimulationX. The proposed
process enables the automatic generation of both fault trees and
FMEA tables in a single run of the tool, allowing the FMEA and fault
trees to share failure data and allowing the FMEA to include
failures caused by multiple basic events. As it is a largely
automated process, it could be easily iterated to enable the
continuous assessment of evolving designs. It provides an automatic
generation of fault trees and FMEA tables for multiple top events in
a single run of the tool. The potential benefits from application of
this technique and tool are substantial and include simplifying the
analysis, easing the examination of effects of design modifications
on safety and keeping the safety analyses consistent with the
design. Furthermore, the presented approach combines the benefits of
simulation and risk analysis in one tool. The benefits of this
approach are demonstrated by the example of a blow out preventer for
a subsea installation valve. |

| Abstract: This study utilized the failure modes and
effects analysis (FMEA) to analyze the risks of green components in
compliance with the European Union (EU) the Restriction of Hazardous
Substance (RoHS) directive in the incoming quality control (IQC)
stage, which is based on a case of an OEM/ODM electronic
manufacturer in Taiwan. There are three indices of FMEA in this
work: the occurrence (0) that can be learned from the testing
report; the likelihood of being detected (D) that refers to the
difficulty of detection: and severity (S) that can be quantified
from the declaration statement and the frequency of green component
used by project. The fuzzy analytic hierarchy process (FAHP) was
applied to determine the relative weightings of four factors, then a
green component risk priority number (GC-RPN) can be calculated for
each one of the components, which are provided by the suppliers to
identify and manage the risks that may be derived from them.
Numerical results indicated that through the use of the proposed
approach, the detected rate of the high risk green components can at
least be improved to 20% while the CC-RPN is above 7, and the
highest risk green components can be increased by 46.2% within the
CC-RPN between 9 and 10. (C) 2008 Elsevier Ltd. All rights reserved. |

| Abstract: In the reliability centered maintenance (RCM)
methodology, the reliability estimates of the system are used to
provide a cost-effective & satisfactory maintenance schedule. In
this paper, a new framework for improvement of the RCM procedure
based on the failure mode and effect analysis (FMEA) is developed.
In order to achieve the objective, first based on the OREDA handbook
classification the critical failure modes of centrifugal pumps &
causes of these failures are identified. Then through the FMEA, the
interactive impacts of these failure causes on both hydraulic &
mechanical operating parameters of the centrifugal pumps (e.g. flow
rate, discharge pressure, vibration) are indicated in linguistic
variables. Next, based on the obtained failure information, the
linguistic rules for failure diagnosis are extracted, and moreover
based on the failure analysis the maintenance intervals are
determined. The ability of the proposed approach to identify and
classify faults, which result in correct and timely diagnosis, will
increase the reliability of the system by maximizing the equipment
availability, and consequently the system performance is improved. |

| Source: INTERNATIONAL JOURNAL OF HYDROGEN ENERGY, 34 (2):
1135-1141 JAN 2009 |
Abstract: In recent years, consumers calling for the
protection of the environment on a regional and global scale are
demanding the use of vehicles that do not emit harmful exhaust. It
is anticipated that one response to this demand is the widespread
use of fuel cell vehicles (FCVs). in order to achieve this, it is
necessary to provide hydrogen fueling stations where FCVs can
refuel.
A liquid hydrogen fueling station was selected for the purpose of
this study as liquid hydrogen can be transported and stored in much
larger quantities than compressed hydrogen gas. The facility of
hydrogen fueling stations must be safe. In order to gauge the safety
measures necessary for liquid hydrogen fueling stations we used a
risk assessment approach. A large number of accident scenarios were
identified using FMEA and HAZOP. The consequence level for each
accident scenario was evaluated using data from liquid hydrogen
explosion experiments. The size of the risk of the accident scenario
was evaluated using a risk matrix and, in order to reduce that risk,
a study was made into the necessary safety measures for liquid
hydrogen fueling stations. As a result of this study, we were able
to gauge the safety measures required to guarantee a high level of
safety for liquid hydrogen fueling stations. (c) 2008 International

| Abstract: IT risk management currently plays more and
more important role in almost all aspects of contemporary
organizations' functionality. It requires reliable and cyclical
realization of its key task which is risk analysis. Literature of
subject presents problems of risk analysis in different way, the
most often skipped or selectively treated the problem of
quantitative methods application for the purpose of risk analysis.
The article presents the issue of one of the most significant stages
of risk analysis which is IT risk assessment, especially focusing on
chosen quantitative methods such as ALE (Annual Loss Eypected)
method, Courtney method, Fisher's method, using survey research
ISRAM model (Information Security Risk Analysis Method) and other
derived ratios. There were also shortly presented chosen qualitative
methods - FMEA (Failure Mode and Effects Analysis) and FMECA
(Failure Mode and Effects Criticality Analysis), NIST SP 800-30
method and CRAMM methodology. |

DIAGNOSIS SYSTEM FOR URBAN TRANSIT |
| Source: INTERNATIONAL JOURNAL OF AUTOMOTIVE TECHNOLOGY,
10 (1): 123-129 FEB 2009 |
| Abstract: Urban transit is a complex system that contains
both electrical and mechanical entities; therefore, it is necessary
to construct a maintenance system for ensuring safety during
high-speed driving. Expert systems are computer programs that use
numerical or non-numerical domain-specific knowledge to solve
problems. This research aims to develop an expert system that
diagnoses the causes of failures quickly and displays measures to
correct them. For the development of this expert system, the
standardization of a failure code classification and the creation of
a Bill of Materials (BOM) were first performed. Through the analysis
of both failure history and maintenance manuals, a knowledge base
has been constructed. Also, for retrieving the procedure of failure
diagnosis and repair linking with the knowledge base, we have built
a Rule-Based Reasoning (RRB) engine with a pattern matching
technique and a Case-Based Reasoning (CBR) engine with a similar
search method. Finally, this system has been developed as web based
in order to maximize accessibility. |

was used for process analysis considering complex dependences among
various parts of the system. On the base of created IDEFO model the
reliability evaluation of the process was completed by contemporary
reliability analysis (RA) techniques such as FTA, FMEA, and RBD. As
the reliability analysis has been performed, it was possible to
determine major system problems and to assist in implementation of
design changes and process improvements. |

| Abstract: This paper proposes an approach to develop a
quality/cost-based conceptual process planning (QCCPP). This
approach aims to determine key process resources with estimation of
manufacturing cost taking into account the risk cost associated to
process plan. Quality Function Deployment (QFD) method is used to
select process alternatives. The results of QFD method have been
taken as input to complete process Failure Mode and Effects Analysis
(FMEA). To estimate manufacturing cost, the proposed approach
deploys Activity-Based Costing (ABC) method. Then cost-based FMEA
method is employed to estimate the cost of all risks associated to
studied process plan. The output data gathered in this approach
could be used as the guidelines for detailed process planning in
order to improve product quatity/cost ratio. |

| Abstract: At the present time, Failure Mode and Effect
Analysis (FMEA) technique is frequently used in manufacturing
industry to deal with undesirable situations. These can occur
throughout the various phases of the product life cycle. The
objectives of this research are to analyze and identify potential
problems in the spindle motor assembly process for 2.5-inch hard
disk drives. The process often encounters the problem of hub flange
height failure. The result of this research may reveal the failures
within five steps of the focusing process. The Risk Priority Number
(RPN) of each failure may now be calculated. As a result of this,
the five highest RPNs may be selected in order to take corrective
action. It could be concluded that, by applying the FMEA technique,
all risks in the process have been pinpointed and all recommended
corrective actions have been taken. As a final step, the process can
be improved by a two-factor factorial experiment with the
significant level at 0.05 in order to determine the optimum setup
conditions. By implementing FMEA, the defective parts could be
reduced from 6,294.36 DPPM to 3,788.27 DPPM. |

INDUSTRIES, 22 (1): 25-34 JAN 2009 |
| Abstract: Maintenance process and planning are at the
heart of industrial occupations. Processes and equipments require
controls and strategies to reduce costs and yield loss. Risk Based
Maintenance (RBM) helps in reducing machinery failure rate and
managing actions priorities. This paper proposes a method using
FMECA as an operational tool which unveils productivity improvement
areas. it demonstrates that it is possible to use FMECA method in a
more dynamic environment, continuously updated by operational
events. The article proposes a risk based maintenance method, which
relies on the regular and automatic update of equipments risk
analyses including equipment failure history. The method gives
up-to-date information about equipments' risks. The article is
structured in four parts. After a risk management domain literature
overview, the paper presents a new risk based maintenance method. A
case study in semiconductor industry shows that FMECA can be
employed in a dynamic way for managing maintenance activities. The
proposed model simplifies and makes more reliable risks
identification and estimation. Results and a brief discussion
conclude the article. (c) 2008 Elsevier Ltd. All rights reserved. |

Abstract: A Failure Mode and Effect Analysis (FMEA) at
component level was done to study safety-relevant implications
arising from possible failures in performing remote handling (RH)
operations at ITER facility [1].
Autonomous air cushion transporter, pallet, sealed casks and tractor
movers needed for port plug mounting/dismantling operation were
analysed. For each sub-system, the breakdown of significant
components was outlined and, for each component, possible failure
modes have been investigated pointing out possible causes, possible
actions to prevent the causes. consequences and actions to prevent
or mitigate consequences.
Off-normal events which may result in hazardous consequences to the
public and the environment have been defined as Postulated
Initiating Events (PIEs). Two safety-relevant PIEs have been defined
by assessing elementary failures related to the analysed system.
Each PIE has been discussed in order to qualitatively identify
accident sequences arising from each of them.
As an output of this FMEA study, possible incidental scenarios,
where the intervention of rescue RH equipments is required to
overcome critical situations determined by fault of RH components,
were defined as well. Being rescue scenarios of main concern for
ITER remote handling activities, such families could be helpful in
defining the design requirements of port handling systems in general
and on RH transfer system in particular. Furthermore, they could be
useful in defining casks and vehicles to be used for rescue
activities. (C) 2008 Elsevier B.V. All rights reserved. |

Abstract: A failure mode and effect analysis (FMEA) at
component level was done to study possible safety relevant
implications arising from failures in European test blanket modules
(TBMs) for ITER: the helium cooled pebble bed (HCPB) and the helium
cooled lithium lead (HCLL) TBMs.
The following sub-systems have been analysed by this study: TBM, TBM
port Plug (PP), inter-space and Port Cell equipment, Helium Coolant
System (HCS). Coolant Purification System (CPS), coolant pressure
control system, PbLi ancillary system and tritium extraction system.
The present study is focused on the modules that will operate in the
last period of the high duty cycle D-T phase of ITER, the plant
integration TBM (PI-TBM) for the HCPB and the integral TBM (IN-TBM)
for the HCLL.
For both modules, six PIEs have been highlighted as the ones more
relevant to be Studied with deterininistic assessments. (C) 2008

| Abstract: This paper presents summary of preliminary
safety assessment of the water-cooled solid breeder (WCSB) test
blanket module (TBM) proposed by Japan for the ITER TBM test
program. For the purpose of basic evaluation of source terms oil
nuclear heating and radioactivity generation, distribution of
neutron flux, tritium breeding ratio, nuclear heating, decay heat
and induced activity of radioactive waste are calculated. For the
purpose of occupational radiological exposure evaluation,
radiological isotope (RI) inventories. i.e., tritium in the breeder
pebble bed, tritium ill purge gas, permeated tritium in cooling
system and active corrosion product (ACP) in the cooling system, are
estimated. Failure mode effect analysis (FMEA) has been carried out
for identification of the postulated initiating events (PIEs) that
need safety evaluation. The PIEs are Summarized into three groups,
i.e., release of RI, pressurization and heatup. With respect to PIEs
about release of RI, the maximum released RI is evaluated for three
RI inventories. i.e., RI in vacuum vessel (VV) (tritium and
radioactive dust), RI in purge gas (tritium) and RI in coolant
(tritium and ACP). With respect to the PIEs about pressurization,
the maximum pressures of the compartments nearby the pipes of
cooling system are evaluated. (C) 2008 Elsevier B.V. All rights

| Title: Six Sigma(A (R)) can be dangerous to your health |
| Source: ACCREDITATION AND QUALITY ASSURANCE, 14 (1):
49-52 JAN 2009 |
| Abstract: Six Sigma(A (R)) is a popular quality program
that has been applied to clinical laboratory assays. Sigma is
calculated as (TEa - bias)/CV and these sigma numbers are often
claimed as a sole measure of quality based on medical requirements.
But these sigma calculations do not account for all results. An
additional set of wider limits must be added, such that all data are
accounted for. This gives a minimum of three zones: zone A, where
95% of the data should be; zone C, where there should be no data;
and zone B, where 5% of the data is allowed. An additional problem
is that sigma calculations are often based on valid analytical data,
meaning that pre-analytical and post-analytical errors are excluded.
Also, samples that are flagged by the system and produce no results
are, of course, excluded, but delayed results can cause patient
harm. A better measure of assay quality can be provided by a failure
mode effects analysis (FMEA), which attempts to assess the
probability of failure and its severity for every possible failure
mode. In this paper, an example of what is entailed is described for
two failure modes and the overall process is outlined. The amount of
effort required for a full FMEA is beyond virtually any clinical
laboratory. Some compromises are suggested. Calculating sigma
values, which have little meaning about patient harm, is not
recommended. |

| Title: Risk evaluation in failure mode and effects
analysis using fuzzy weighted geometric mean |
| Source: EXPERT SYSTEMS WITH APPLICATIONS, 36 (2):
1195-1207 Part 1 MAR 2009 |
| Abstract: Failure mode and effects analysis (FMEA) has
been extensively used for examining potential failures in products,
processes, designs and services. An important issue of FMEA is the
determination of risk priorities of the failure modes that have been
identified. The traditional FMEA determines the risk priorities of
failure modes using the so-called risk priority numbers (RPNs),
which require the risk factors like the occurrence (O), severity (S)
and detection (D) of each failure mode to be precisely evaluated.
This may not be realistic in real applications. In this paper we
treat the risk factors O, S and D as fuzzy variables and evaluate
them using fuzzy linguistic terms and fuzzy ratings. As a result.
fuzzy risk priority numbers (FRPNs) are proposed for prioritization
of failure modes. The FRPNs are defined as fuzzy weighted geometric
means of the fuzzy ratings for O, S and D, and can be computed using
alpha-level sets and linear programming models. For ranking purpose.
the FRPNs are defuzzified using centroid defuzzification method, in
which it new centroid defuzzification formula based on alpha-level
sets is derived. A numerical example is provided to illustrate the
potential applications of the proposed fuzzy FMEA and the detailed
computational process of the FRPNs. (C) 2007 Elsevier Ltd. All

| Title: Failure mode and effects analysis using a
group-based evidential reasoning approach |
| Source: COMPUTERS & OPERATIONS RESEARCH, 36 (6):
1768-1779 JUN 2009 |
| Abstract: Failure mode and effects analysis (FMEA) is a
methodology to evaluate a system, design, process or service for
possible ways in which failures (problems, errors, risks and
concerns) can occur. It is a group decision function and cannot be
done on an individual basis. The FMEA team often demonstrates
different opinions and knowledge from one team member to another and
produces different types of assessment information such as complete
and incomplete. precise and imprecise and known and unknown because
of its cross-functional and multidisciplinary nature. These
different types of information are very difficult to incorporate
into the FMEA by the traditional risk priority number (RPN) model
and fuzzy rule-based approximate reasoning methodologies. In this
paper we present an FMEA using the evidential reasoning (ER)
approach, a newly developed methodology for multiple attribute
decision analysis. The proposed FMEA is then illustrated with an
application to a fishing vessel. As is illustrated by the numerical
example, the proposed FMEA can well capture FMEA team members'
diversity opinions and prioritize failure modes under different
types of uncertainties. (C) 2008 Elsevier Ltd. All rights reserved. |

| Abstract: In this paper the possibilities of a
qualitative and systematic procedure for the selection of the most
developable concept in early design stages and the transfer of the
gained information into a failure mode and effects analysis are
shown. Further, the possibility of deriving reasonable lifetime
distributions from the FMEA assessment values for the description of
the system behaviour is demonstrated. With this integrative
qualitative approach new products can be accompanied with a
procedure, which passes on all its information without any losses,
over the complete product design cycle. Copyright (C) 2008 John

(FMEA) and cause and effect analysis for industrial processing of
common octopus (Octopus vulgaris) - Part II |
| Source: INTERNATIONAL JOURNAL OF FOOD SCIENCE AND
TECHNOLOGY, 44 (1): 79-92 JAN 2009 |
| Abstract: Failure mode and effect analysis (FMEA) model
was applied in conjunction with cause-and-effect analysis for the
risk assessment of octopus processing (Octopus vulgaris). Critical
control points were identified and implemented in the
cause-and-effect diagram (also known as Ishikawa, tree diagram and
fishbone diagram). The main emphasis was put on the quantification
of risk assessment by determining the risk priority numbers (RPN)
per identified processing hazard. Chemically contaminated product,
decomposed raw materials, scombrotoxin presence in the final
product, incorrectly labelled product, storage in cans (foreign
matter) and defective products, were identified as those with the
highest RPN (378, 294, 280, 252, 245 and 144 respectively) and
corrective actions were undertaken. Following the application of
corrective actions, a second calculation of RPN values was carried
out, leading to considerably lower values (below the upper
acceptable limit of 130). It is concluded that the incorporation of
FMEA analysis within the ISO2200 system of an octopus-processing
industry is imperative. |

| Title: A Comparative Presentation of Implementation of
ISO 22000 Versus HACCP and FMEA in a Small Size Greek Factory
Producing Smoked Trout: A Case Study |
| Source: CRITICAL REVIEWS IN FOOD SCIENCE AND NUTRITION,
49 (2): 176-201 2009 |
| Abstract: ISO 22000 is the new standard bound to replace
HACCP on issues related to food safety. Although several companies,
especially the big ones, have either implemented or are on the point
of implementing ISO 22000, there are many others which are rather
timid and/or reluctant to implement it. The main reason behind that
is the lack of information and the fear that the new standard is too
demanding in terms of bureaucratic work. This paper aims at making a
comparative presentation of how the two systems can be applied to a
small smoked salmon producing company thereby facilitating the
emergence of the differences. The main difference is that in ISO
22000 systems like Good Manufacturing Practice and Good Hygiene
Practice are prerequisites thus leading to lower number of CCPs. In
this case study for example, the number of CCPs dropped from eight
(8) in HACCP to four (4) in ISO 22000. Furthermore, the Failure Mode
and Effect Analysis was applied to the smoked trout manufacturing
process in an attempt to calculate quantitatively the Risk Priority
Number (RPN) and to find out whether it can be effectively
correlated to ISO 22000 and/or HACCP. RPN was found to be higher
than 130 for eight steps, in close agreement with HACCP, thereby
indicating that corrective actions will have to be undertaken. |
