Failure Mode and Effects Analysis Using Data Envelopment Analysis

In this paper, we propose a bounded dea based model to measure the overall risk of failuremodes. in the proposed model risk is measured within the range of an interval, whoseperformance is definitely superior to any one. the risks, obtained from bounded deamodels, turn out to be all intervals and are referred to as interval risk, which combine thebest and the worst relative risk in a reasonable manner to give an overall assessment ofperformances for all failure modes. assessor’s preference information on input and outputweights is also incorporated into bounded dea models reasonably and conveniently. apractical example is provided to compare the proposed model with those in the literature.
