G400

Foundations of Reliability Engineering Data Analysis and Modeling

Learn Life Data Analysis (aka Weibull Analysis) and Other Essential Reliability Methods

The immensely popular G400 course sets the foundation for all subsequent seminars by introducing and familiarizing the attendee to the fundamental concepts in reliability engineering mathematics, from basic data analysis and modeling to advanced methods and concepts. It begins with an in-depth discussion of the fundamentals of Weibull and Life Data Analysis and continues by expanding the learned concepts to more advanced subjects.

G400 presents concepts and software that will help you to:

  • Understand how life data analysis methodologies can be applied when you need to understand and communicate how a product will perform over time, such as:
    • Setting meaningful reliability targets, demonstrating whether an item meets the specification and/or effectively communicating performance estimates to management.
    • Identifying whether an item will experience infant mortality and/or wearout and making predictions about performance during the useful life (or warranty) period.
    • Evaluating suppliers and/or comparing designs based on reliability.
  • Become familiar with the applications of other essential reliability data analysis methods, such as ALT, RBDs and RGA.

Note that G400A is a truncated version of G400 that covers only the first three days.
