1.4 Examples in Reliability and Survival Studies 1.4.1 Electro‐Explosive Devices Data
ОглавлениеFan et al. (2009) considered data, presented in Table 1.1, on 90 electro‐explosive devices under various levels of temperature at different inspection times. Ten devices under test at each condition were inspected to see whether there were any failures or not at each inspection time for each temperature setting. These data were then used to estimate the reliability of electro‐explosive devices at different mission times under the normal operating temperature.
