      Lifetime information obtained from one‐shot devices is very limited as the entire data are either left‐ or right‐censored. For this reason, the analysis of one‐shot device testing data poses a special challenge. This book provides several statistical inferential methods for analyzing one‐shot device lifetime data obtained from accelerated life‐tests and also develops optimal designs for two mainstream accelerated life‐tests – constant‐stress and step‐stress accelerated life‐tests – that are commonly used in reliability practice. The discussions provided in the book would enable reliability practitioners to better design their experiments for data collection from efficient accelerated life‐tests when there are budget constraints in place. This is important from estimation and prediction point of view as such optimal designs would result in as accurate an inference as possible under the constraints imposed on the reliability experiment. Moreover, R codes are presented within each chapter so that users can try out performing their own analysis on one‐shot device testing data.

      In addition, the inferential methods and the procedures for planning accelerated life‐tests discussed in this book are not only limited to one‐shot devices alone but also can be extended naturally to accelerated life‐tests with periodic inspections (interval‐censoring) and those with continuous monitoring and censoring (right‐censoring). The book finally concludes by highlighting some important issues and problems that are worth considering for further research. This may be especially useful for research scholars and new researchers interested in taking on this interesting and challenging area of research in reliability theory and practice.

      It is possible that some pertinent results or references got omitted in this book, and we assure you that it is due to inadvertency on our part and not due to scientific antipathy. We will appreciate greatly if the readers inform us of any corrections/omissions, or any comments pertinent to any of the discussions in the book!

      Finally, the first author (NB) wishes to state to his older daughter, Ms. Sarah Balakrishnan, that though she lost out on getting his Volvo car due to a major car accident, she should be heartened by the fact that the accident resulted in the germination of his interest and ideas on one‐shot devices (airbags), and ultimately this book solely dedicated to the topic!

      1.1 Brief Overview

      One‐shot device testing data analyses have recently received great attention in reliability studies. The aim of this chapter is to provide an overview on one‐shot device testing data collected from accelerated life‐tests (ALTs). Section 1.2 surveys typical examples of one‐shot devices and associated tests in practical situations. Section 1.3 describes several popular ALTs, while Section 1.4 provides some examples of one‐shot device testing data that are typically encountered in reliability and survival studies. Finally, Section 1.5 details some recent developments on one‐shot device testing data analyses and associated issues of interest.

      Valis et al. (2008) defined one‐shot devices as units that are accompanied by an irreversible chemical reaction or physical destruction and could no longer function properly after its use. Many military weapons are examples of one‐shot devices. For instance, the mission of an automatic weapon gets completed successfully only if it could fire all the rounds placed in a magazine or in ammunition feed belt without any external intervention. Such devices will usually get destroyed during usual operating conditions and can therefore perform their intended function only once.
