Course Descriptions: Reliability Engineering is concerned with the design, implementation, and prediction of the life profile of a system or component using a disciplined analysis approach that has strong roots in statistics, mathematics and engineering. Given a system, subsystem or component, one of the major challenges is to understand the inherent failure mechanisms that govern the system behavior as well as the development of the appropriate analytical scheme to determine system or component life profile. The problem becomes even daunting due to aging and related transient phenomenon as well as the lack of meaningful data. In addition the related challenge of maintenance intervention which has the ultimate goal of prolonging system/component life or enhancing performance of repairable systems. There is also the issue of reliability growth which speaks to system or component reliability improvement.
Today, those challenges still persist especially as companies strive to shorten time to market in order to gain market share. Equally important the issue of system safety in the larger context of design for survivability and performability continues to be of concern to designers and engineers. In this course, we will examine analytical approaches for estimating reliability for components and for system of components. We will also explore some of the important metrics used to assess reliability performance for commercial versus military applications, and for repairable versus nonrepairable systems. The idea of formulating the reliability function without necessarily assuming a known underlying probability structure is without question a key element in reliability assessment and so it is important to develop the analytical scheme in order to address this important issue.
