Understanding Terms and JargonBefore any discussion involving these terms can take place it is essential that the word FAILURE is fully defined and understood. Unless the failed state is defined it is impossible to explain the meaning of Quality or of Reliability.作者: jabber 時(shí)間: 2025-3-22 08:04

Interpreting Data and Demonstrating ReliabilityThis chapter deals with the interpretation of failure rates and MTBFs for the special case where random failures are assumed. We are dealing thus with constant failure rates and the equality λ = 1/. applies. The next chapter explains the analysis of variable failure rates.作者: 全神貫注于 時(shí)間: 2025-3-22 16:49
Interpreting Variable Failure Rate Data by Probability PlottingThe Bathtub Curve in figure 3.5 showed that, in addition to random failures, there are distributions of increasing and decreasing failure rate. In these variable failure rate cases it is of little value to consider the actual failure rate since only Reliability and MTBF are meaningful.作者: 顧客 時(shí)間: 2025-3-22 20:08
