Reliability Engineering: Evaluation of Various Growth Models

Reliability goals are generally associated with a reliability growth program. A program may have more than one reliability goal. For e.g. there may be a reliability goal associated with failures resulting in unscheduled maintenance actions & a separate goal associated with those failures causing a mission abort or catastrophic failure. Other reliability goals may be associated with failures modes that are safety related. The monitoring of the increase of the product’s reliability through successive phases in a reliability growth analysis (RGA) concerns itself with the quantification and assessment of parameters (or metrics) relating to the products reliability growth over time. Reliability growth management addresses the attainment of the reliability objectives through planning and controlling of the reliability growth process.
