Introduction Modern technolog y has develo ped a ten dency to design and man ufa cture equ ipment and systems of greater capi ta l cost , sophis ti cation, complexity, and capa ci ty.

Due to des ign problems and poor produc t suppor t, man ufacturer equ ipment and systems are not able to meet these requirements. However with proper consi derat ion of reli abili ty,availability, maintainabili ty and suppo rtabi lity (RAlv!S) in the design, manufacturing, a nd i ns ta ll at io n p ha se , t he n um be r o f f ai lu re c ou ld b e reduced and their consequen ces minimize d.
