Hot Topics
A Response Surface Approach for Robust Parameter Design
Robust parameter designs have been used widely in industry. In Issue 122 of the Reliability Hotwire, we discussed using Taguchi’s method to design robust products and processes. An example with a cross-array design using ReliaSoft’s DOE++ was given. In this article, we will use a single-array design with response surface method approach for robust parameter design.

Reliability Basics
Bayesian Reliability Demonstration Test Design
For life tests, especially for systems like missiles, sample size is always limited. It is a challenge to get accurate reliability estimates with limited samples, and Bayesian methods have been used to solve this problem. Weibull++ 8 now offers non-parametric Bayesian reliability demonstration test (RDT) design. Unlike traditional non-parametric test design methods, this new feature allows engineers to integrate engineering knowledge or subsystem testing results into system reliability test design. In this article, we will explain the theory of Bayesian RDT and illustrate how to use Weibull++ to design an efficient reliability demonstration test.

Tool Tips
  • What does the "System is new on start date" option mean in the Weibull++ event log?
  • Can I use different time units for different types of inputs/results in Synthesis applications?
