Web除了MTBF指标，还有其他可靠性量化表征指标，如故障率λ（Failure Rate）和年化故障率AFR（Annualized Failure Rate）。 故障率λ ： SSD关键元器件选型时、需要确保每个元器件的故障率 λ 达标。 相比故障率指标，MTBF的定义更加直接，也更适用于表现系统级的可 … Web9 apr. 2024 · The system’s MTTF is depicted in Fig. 4.5 and Table 4.3. The importance of MTTF analysis is to determine how much the system's MTTF changes with respect to each failure rate, in the event that a failure could be catastrophic to the system, so that failure of that subsystem/unit can be avoided.
Web4 iun. 2024 · Similar to MTBF, the mean time to failure (MTTF) is used to predict a product’s failure rate.
