AMSAA MODEL -
A reliability growth model developed at the U.S. Army Materiel Systems Analysis Activity by Larry H. Crow. Can be viewed as a stochastic extension (a non- homogeneous Poisson process) of the Duane model.
DUANE MODEL -
A reliability growth model developed by J.T. Duane based on the empirical observation of straight-line decrease in failure rate versus cumulative test time when plotted on log-log paper.
Environmental Stress Screening: A stimulation process intended to induce early detection and correction of workmanship flaws, weak parts, etc., by the application of thermal and vibrational stresses to electronic products.
Failure Reporting Analysis and Corrective Action System.
Full-Scale Engineering Development: The acquisition phase immediately preceding production.
Reliability Development/Growth Test: A formal environmental test simulating operational parameters in which failures are welcome to achieve reliability growth via the TAAF process. In such a test, growth also may be analyzed; for example, by use of the AMSAA model.
Reliability Development Test: See RD/GT
RELIABILITY GROWTH -
The improvement of reliability as a result of maturation--that is, the elimination or reduction of specific, individual failure causes by improvements in design or processes.
Reliability Growth Test: See RD/GT.
TAAF - Test, Analyze, and Fix: The
process by which growth is achieved.
