G511

Application of Reliability Growth Models in Developmental Testing and Fielded Systems

Learn Applications for Crow (AMSAA), Power Law and Other RGA Models

G511 provides an overview of reliability growth analysis models and their application for data captured from developmental (reliability growth) testing and also from fielded (repairable) systems.

The course presents concepts and software tools that you could use to help your organization:

  • Analyze data from developmental tests in order to quantify reliability growth and determine the feasibility of achieving reliability goals with a given test/fix strategy.
  • Analyze data from fielded systems in order to calculate optimum overhaul times and other results without the detailed data sets that would normally be required for repairable system analysis.
