How to use Weibull to analyze historical data

In our webinar series “How to Use Your Tools”. We spent about 30 to 40 minutes covering the topic of using Weibull to analyze historical information. This is an educational webinar intended to teach our users and prospective users how to better use our tools to properly model their systems.

Weibull is another treasure to add to your analysis. Weibull analyzes historical failure or repair data and assigns probability distributions which represent the failure or repair characteristics of a given failure mode.
The failure distribution assigned to a given set of times to failure (known as a Weibull set) may be assigned to basic events or generic failure models in the Fault Tree Analysis module and to reliability blocks or generic failure models in the RBD analysis.

The Weibull Analysis Module analyses times-to-failure and time-to-repair data using the following distributions:
• Exponential Distribution
• 1-Parameter Weibull Distribution
• 2-Parameter Weibull Distribution
• 3-Parameter Weibull Distribution
• Weibayes
This webinar is the 6th webinar in this series, topics already covered:

• Fault Tree Analysis
• Fault Tree Analysis and the IEC 61508
• Data Links FMECA to Fault Tree
• Event Tree Analysis as part of a Fault Tree Study
• How to use Markov in an FTA or RBD
• How to use Weibull to analyse historical information

Past webinars can be viewed on our blog . Its not necessary to have attended past webinar to attend our current webinar. However, for a bit of free training it will be useful to check out the series so far.
