WebMar 17, 2024 · Numerical Reliability Analysis Scope and Description. This topic covers prediction of the reliability of spacecraft electrical systems. The goal of a numerical reliability analysis is typically to obtain a probability of failure and a mean time between failures (MTBF) for a given system. WebHow do you calculate reliability from failure rate? For example, if two components are arranged in parallel, each with reliability R 1 = R 2 = 0.9, that is, F 1 = F 2 = 0.1, the resultant probability of failure is F = 0.1 0.1 = 0.01. The resultant reliability is R = 1 0.01 = 0.99.
