Topics:

Production Line Optimization
Want increased throughput? Less variance? Shorter time to steady state? Here's how... (Intermediate)

DORT, Design of Ongoing Reliability Tests
Estimate early-life reliability, the dependent variable, as a function of independent variables, primarily age. (Elementary)

Renewal Estimation Without Renewal Counts
Estimate field reliability from grouped ships and renewal counts, without knowing how many renewals have occurred. (Intermediate)

Field Reliability Without Life Data
Estimate and use field reliability. Gaap requires statistically sufficient data. Examples from Firestone, EEPROMs, computers. (Intermediate)

Credible Reliability Prediction
[ASQ-Reliability Division monograph, http://www.asq-rd.org/publications.htm ]. Make credible MTBF and reliability predictions for complex systems with redundancy. Use observed field reliability of comparable products or parts. (Intermediate)

DART, Design of Accelerated Reliability Tests
Use a piecewise linear failure rate to efficiently test reliability and control process defects. (http://www.ewh.ieee.org/r6/scv/rs/articles/DART.pdf). (Intermediate)

Reliability Estimation from Current Status Data
Suppose you knew only whether products or births were still alive or dead?

How to Forecast Repairable System Failures
Actuarial forecasts and prediction limits on failures include sample and failure rate function extrapolation uncertainties.

LED Reliability Analysis
Stock price stochastic differential equation models deterioration and implies L70 lifetime reliability has inverse Gauss distribution.
