Abstract:
|
Traditionally, system engineering and system reliability estimation have been separate activities. Reliability methods have focused on predicting how a particular inventory of systems will age and for how long a given percent will remain functional. This effort has been predicated on the assumption that a system architecture is defined, and that a sufficient body of testing (whether derived from functional or component sources) exists. In contrast, system engineering has focused on the determination of an architecture that can be validated against customer requirements. In this paper, I will discuss these issues, and describe how concurrent system engineering approaches can be included in reliability prediction efforts.
