RS 511 Training Seminar
Application of Reliability Growth Models in Developmental Testing
and Fielded Systems

RS 511 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. ReliaSoft’s RGA software is used for hands-on practical examples. Topics include reliability growth tracking and projection models and calculating optimum overhaul times and other metrics for 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.
