Mtbf from failure rate
WebFor example, let’s say the radar system shown in Figure 1 has a requirement for a 10,000 hour mean-time-between-failure (MTBF). In order to determine if this goal can be achieved, failure rate data on each item is determined, as shown in Table 1. If an exponential failure distribution is assumed, indicating that failures are expected to occur ... WebThe failure rate predicts the average number of hours that an item, assembly, or piece part will operate before it fails, while the MTBF predicts the average elapsed time between …
