Prioritizing Potential Risks based on Failure Mode and Effects Analysis Using Data Envelopment Analysis: a case study

The need to establish power plants to supply the required electricity of the country has been rising due to increasing demand levels as well as the lack of governmental resources. Furthermore, the available traditional attitude in performing and conducting power plant projects has made government seek a modern attitude. This paper tries to use the topics that have been employed in automotive industry of the company for many years to detect and analyse failure reasons as well as the solutions that are suggested to prevent and improve them. The present study has used Failure Mode & Effects Analysis along with Data Envelopment Analysis to evaluate 17 failure modes of South Esfahan Power Plant. Severity, Occurrence and Detection are 3 failure factors considered in this study. Failure mode dealing with Scaling on rotor and diaphragms blades has the highest importance with the highest Risk Priority Number,Severity and its first grade.
