The adaptive type-II progressive hybrid censoring has the advantage of saving both the total
test time and the cost of the experiment; also it increases the efficiency of the statistical …

A reliability experimenter is often interested in studying the effects of extreme or varying
stress factors such as load, pressure, temperature and voltage on the lifetimes of …

Based on progressively type-II censored samples, constant-partially accelerated life tests
(PALTs) when the lifetime of items under use condition follow the two-parameter Burr type …

Step-stress models form an essential part of accelerated life testing procedures. Under a
step-stress model, the test units are exposed to stress levels that increase at intermediate …

The step-stress accelerated life tests allow the experimenter to increase the stress levels at
fixed times during the experiment. The lifetime of a product at any level of stress is assumed …

In this article, we consider a simple step-stress life test in the presence of exponentially
distributed competing risks. It is assumed that the stress is changed when a pre-specified …

In this article, we investigate the optimization problem when the competing risks data come
from a progressive type II censoring in an accelerated life test with multiple levels of constant …

In a life testing experiments, accelerated life tests (ALTs) model has provided a significant
decrease for the cost and time. The problem of statistical inference of constant-stress ALTs …

In this paper, the problem of constant partially accelerated life tests when the lifetime follows
the generalized exponential distribution is considered. Based on progressive type-II …

This paper gives a reliability sampling plan for progressively type I interval censored life
tests when the lifetime follows the exponential distribution. We use the maximum likelihood …
