Development of Fuzzy Failure mode effect analysis (FFMEA) model for Risk Priority Number (RPN) analysis

  title={Development of Fuzzy Failure mode effect analysis (FFMEA) model for Risk Priority Number (RPN) analysis},
  author={Ashwani Kharola and Sb Singh},
Failure mode effect analysis (FMEA) is one of the well known and widely used technique of Quality Management. The purpose of FMEA is to examine failure modes in different products, designs, business processes/services. Traditional FMEA technique involves the determination of Risk Priority Number (RPN) which was obtained by multiplication of three risk factors i.e. Occurrence (O), Severity (S) and Detection (D). In this study we have treated the risk factors as fuzzy variables and evaluate them… 

Graded Approach Establishment for the HTGR Maintenance Activities Using Modified Fuzzy FMEA & Expert Judgement Methodology

Grading is an important step of the Nuclear Power Plant (NPP) operation & maintenance activities. However, there are several grading difficulties for the High Temperature Gas Reactor (HTGR) as well

Using Fuzzy FMEA to Increase Patient Safety in Fundamental Processes of Operating Room

F fuzzy logic is employed to overcome shortages in FMEA, and two months after implementation of corrective actions, RPN was calculated, and results showed 8.23 percent reduction averagely.

A review of applications of fuzzy sets to safety and reliability engineering

Fuzzy-FMSA: Evaluating Fault Monitoring and Detection Strategies Based on Failure Mode and Symptom Analysis and Fuzzy Logic

Failure mode and symptoms analysis (FMSA) is a relatively new and still not very much employed variation of failure modes, effects and criticality analysis (FMECA), a technique broadly used in reli...

The OWA distance operator and its application in business failure

A goodness index based on Hamming distance and ordered weighted averaging distance (OWAD) is developed, which is useful to make decisions and enrich the results of diagnostic fuzzy models and facilitate the experts’ task in decision-making.

Utilization of risk priority number to systems-theoretic process analysis: A practical solution to manage a large number of unsafe control actions and loss scenarios

An additional procedure was suggested to system-theoretic process analysis to ensure a systematic evaluation, screening, and prioritization of analysis results, and the risk priority number approach was adopted to evaluate the criticality of the results of analyses.

Risk Analysis of Propeller Failure due to Wave-Induced Oscillation

In this paper, a risk analysis is carried out to identify the causes of propeller failure by wave-induced oscillations. Propellers need to be optimized for their actual operating condition rather

Failure Mode and Effect Analysis for CNC machines used in GG Valves Industry

India beat England by six wickets in the one-day international series to win the Champions Trophy for the second time in three years.




Failure mode and effects analysis (FMEA) is one of the well-known techniques of quality management. The purpose of FMEA is to identify possible failure modes of the system components, evaluate their

Fuzzy assessment of FMEA for engine systems

Fuzzy FMEA with a guided rules reduction system for prioritization of failures

A guided rules reduction system (GRRS) is proposed to regulate the number of rules required during the fuzzy RPN modeling process and the effectiveness of the proposed GRRS is investigated using three real‐world case studies in a semiconductor manufacturing process.

Fuzzy FMEA Analysis for Identification and Control of Failure Preferences in ERP Implementation

ERP began in the 1960s as material requirements planning, an outgrowth of early efforts in bill of material processing. However ERP Implementing as a new set of decision-making processes is a major

Cost‐oriented failure mode and effects analysis

By implementing the cost‐oriented FMEA, quality management can be improved and in order to decide on improvement actions, costs arising from faults detected by the customer, costs of faults detected within the boundaries of the company and costs associated with false positive inspection results should be included in the evaluation of potential failures.

A Chance Constrained Multiple Objective Goal Programming Model of Fuzzy QFD and FMEA: Model Development

The proposed MOCC-QFD-FMEA model is a right model to include variety of objectives as well as the risk factors into the model of the problem, and takes into consideration the concept of Fuzzy set.
