This interdisciplinary option is offered by the Department of Mechanical Engineering. Typical areas of study include topics such as the mechanisms and physics of failure, methods of design for reliability, maintainability engineering, life cycle costing and equipment sparing policies. There are five core courses plus a one-credit seminar course required in reliability engineering and five technical electives (at least 6 courses at the 600 level or above).

Technical Electives
Approved courses in reliability engineering or approved technical electives in other programs such as systems engineering, electronic packaging materials and manufacturing, and mechanical engineering.
ENPM 808Q Probabilistic Methods in Engineering Mechanics (3) The objective is to understand probability concepts as applied to problems in engineering mechanics with particular emphasis on mechanical system reliability. The probability of failure (and its complement, reliability) will be calculated for several failure mechanisms; exceeding ultimate strength, yielding, fatigue, fracture, buckling, etc.
ENPM 808X Engineering Reliability & Risk Assessment (3) With ever-increasing frequency, aerospace professionals are being tasked with quantifying the reliability and the subsequent risk of aerospace systems. This is most evident in the engineering efforts for maintaining aging aircraft systems. Indeed, denumerable reliability and risk are the very core problems of the RCM (reliability centered maintenance) concept. Without objectively calculated reliability and risk assessments, life extension issues become clouded in vaguely expressed uncertainties. The vagueness engenders a lack of confidence in the knowledge base, which in turn engenders substantial conservatism in the decision-making process.
