Quantifying parameters for Bayesian prior assumptions when estimating the probability of failure of software [PDF]

Software reliability has become increasingly important, especially in life-critical situations. The ability to measure the results of testing and to quantify software reliability is needed. If this is accomplished, a certain minimum amount of reliability

A Bayesian Approach to Step-Stress Partially Accelerated Life Testing for a Novel Lifetime Distribution

Axioms
In lifetime testing, the failure times of highly reliable products under normal usage conditions are often impractically long, making direct reliability assessment impractical.

Fatigue Reliability Analysis of Wind Turbine Cast Components

Energies, 2017
The fatigue life of wind turbine cast components, such as the main shaft in a drivetrain, is generally determined by defects from the casting process.

Accelerated Life Test for Reliability Evaluation of Pneumatic Cylinders

IEEE Access, 2018
Pneumatic cylinders are intended to be designed for high reliability and long lifetimes. Evaluating such designs through conventional life tests is difficult as the affordable test time is too short to generate a meaningful amount of failure data.

Parameter Estimates of General Failure Rate Model: A Bayesian Approach [PDF]

, 2014
The failure rate function plays an important role in studying the lifetime distributions in reliability theory and life testing models. A study of the general failure rate model $r(t)=a+bt^{\theta-1}$, under squared error loss function taking $a$ and $b$
