International Journal of Reliability and Safety (IJRS), Vol. 11, No. 3/4, 2017

Abstract: This study deals with the development of a methodology for maintenance policy selection by assimilating the various factors as an alternative to traditional failure mode effect analysis. This methodology is based upon Dempster-Shafer theory (DST) of evidence which helps the plant managers/engineers to contrive an efficacious priority rating of various items of equipment/components under conditions of epistemic uncertainty considering the various parameters. A case study of a distillery plant is undertaken for selection of a suitable maintenance policy for the various items of equipment/components of the plant using the proposed methodology.
