Systems Reliability Analysis

During the conceptual design studies that NASA often performs, there is a need to bring reliability predictions into the screening process as one of the evaluation metrics (along with mass, power, cost, and any other metrics). Since detailed subsystem descriptions are generally unavailable during the conceptual design phase, a good deal of experience is required to estimate component failure rates based on mission duration, on-off cycles, degree of redundancy, and similarity of novel new parts to historical database components.  By performing such system-level reliability analyses, N&R has contributed to design decisions made by NASA for next-generation launch vehicles and interplanetary spacecraft including the Earth Departure Stage (EDS) and the Orion Service Module.
