A Chi-Squared Accelerated Reliability Growth (CARG) model has been developed as a new method for single- and multi-stress level reliability growth life data analysis. The model is relatively easy to apply and is very practical. The CARG method is appropriate when an exponential distribution can be assumed. The chi-squared distribution has been used as a traditional method of identifying reliability...
Planning for reliability growth requires a disciplined approach rather than an “ad hoc” approach. The reliability growth program must be devised early so that adequate test phase lengths and test assets can be planned to optimize reliability growth opportunities. The primary goal of the Reliability Growth Test (RGT) is to improve the probability of demonstrating achievement of the reliability requirement...
Reliability growth planning is an important part of the reliability growth process. Its purpose is to provide achievable benchmarks throughout developmental testing in order to evaluate whether the project is on track to meet its requirement. Different models produce different growth curves. This paper compares two popular models, the Planning Model Based on Projection Methodology (PM2) and Crow Extended...
The reliability and Design for Reliability (DFR) guidelines, discussed are based on established design principles and rapid innovation methods for failure avoidance. These guidelines can move you, your design team and your organization from one which simply tracks, charts, and reports reliability, to one that engages meaningful Design for Reliability (DFR) activities and initiates powerful but inexpensive...
