“…However, for such highly reliable products, it is not an easy task to assess the product reliability within short test durations because sufficient lifetime data are generally required to precisely estimate product's lifetime (failure time, time-to-failure) distribution. Precise reliability estimation is an important part of subsequent managerial decisions such as determining the burn-in time (Sheu & Chien, 2005;Tsai, Tseng, & Balakrishnan, 2011;Ye, Shen, & Xie, 2012), establishing a warranty or maintenance policy (Chien, 2008;Jung & Park, 2003), or pricing extended warranties. To increase the likelihood of observing failures, Accelerated Life Test (ALT) is commonly used by exposing and testing products under a higher stressed condition (e.g., higher temperature, voltage, pressure, vibration, electric current, etc.).…”
