Accelerated Life Testing Data Analyses for One-Shot Devices

Abstract

One-shot device testing data arises from devices that can be used only once, for example, fire extinguishers, electro-explosive devices, and airbags in cars. In life tests, only the conditions of the tested devices at a specified time can be observed, instead of their actual lifetimes. Such data is therefore of either left- or right-censored. For these heavily censored data, there is an increasing need to develop innovative techniques for reliability analysis. In this chapter, we provide an overview of analyses of one-shot device testing data collected from accelerated life tests and discuss some statistical issues on the statistical estimation and inference as well as optimal designs of accelerated life tests for one-shot devices.
