The origins of quality engineering are in manufacturing, where quality engineers apply basic
statistical methodologies to improve the quality and productivity of products and processes …

Progressive-stress accelerated life testing (PSALT) is a special type of experiment that tests
the lifetime of a product with continuously varying stress levels. Due to the limitations of …

In many industries including engineering, biology, and medical science, etc, interval failure
data commonly exist. Utilizing the data to estimate product lifetime is often confounded with …

To solve multiple response optimization problems that often involve incommensurate and
conflicting responses, a robust interactive desirability function approach is proposed in this …

In reliability improvement experiments, engineers are very interested in which factors affect
the reliability of products. Furthermore, they hope to terminate experiment early without …

In accelerated life tests (ALTs), test units may come from different groups (subsampling,
blocking, and clustering) and the group effect is random and significant. The ALTs, in this …

The reliability of products and processes will become increasing important in the near future.
One definition of reliability is “quality over time.” Customers increasing will make their …

Engineers use reliability experiments to determine the factors that drive product reliability,
build robust products, and predict reliability under use conditions. This article uses recent …

Reliability experiments provide important information regarding the life of an item, including
how various factors affect item life. Current analyses of reliability data usually assume a …

Abstract Design of experiment (DOE) is a useful tool to identify significant factors and choose
factor levels for product reliability improvement. In practice, practitioners often ignore random …
