Risk management and improving the processes’ reliability are important in
operations and production management. Failure modes and effects analysis
(FMEA) is regarded as one of the most powerful methods in this area. High
applicability and proper analyzability have caused FMEA to be among the
most important techniques of systems’ risk analysis and safety improvement.
On the other hand, widespread application of this method in various
fields has revealed some weak points and constrains; subsequently many
researchers have offered revisions and modifications on it. In this article,
analytical network process (ANP), a modern and powerful method in
decision-making field, has been used in combination with FMEA (ANPFMEA)
for defeating the shortcomings.
ANP-FMEA considers mutual relationships of hazardous factors, and by
offering certain structure, develops a systematic and flexible view in risk
management scope. The suggested method deploys simple concept of risk
priority number and assigns different importance in the form of power for each
factor. The resulted RPN will cope better with the system, in which it is applied.
This method provides more accurate analysis of risk and, consequently, more
efficient and effective actions, causing attainment and maintenance of more
desirable reliability.
