# Applied Reliability Analysis Course

## Using Reliasoft Weibull++

A little background, motivation, course overview, and a welcome from the instructor, Steven Wachs

## Training Objectives

The key training objectives are summarized below:

- Understand reliability concepts and unique aspects of reliability data
- Understand underlying probability and statistical concepts for reliability analysis
- Develop competency in the modeling and analysis of time-to-failure data
- Use and interpret probability plots for distribution fitting
- Understand reliability metrics and how to estimate and report them
- Handle multiple failure modes in reliability estimation
- Utilize degradation Data and models to predict failure times for life data analysis
- Use nonparametric estimation methods when appropriate
- Determine if reliability specifications are met (at specified confidence level) or whether design improvements are required
- Estimate estimate uncertainty using confidence intervals and bounds
- Estimate reliability of subsystems and systems
- Handle basic series and parallel systems
- Become aware of system reliability activities such as Reliability Block diagramming, Reliability importance, and Reliability allocation
- Develop competency in the planning of reliability tests (sample sizes)
- Use simulation to support estimation test planning
- Develop reliability demonstration test plans (testing time vs. number of units tradeoffs)
- Analyze existing warranty data to predict future returns
- Analyze data from Accelerated Life Tests to estimate reliability at normal use conditions (single stress, multiple stress, time-varying stress models)
- Plan Accelerated Life tests (sample sizes, determination of test stress combinations, allocation of units to stress levels)
- Incorporate degradation data modeling into Accelerated Life Test analysis
- Perform stress-strength analysis using analytical methods, software, and simulation
- Model reliability from binary response data (i.e. pass/fail)
- Analyze repair data from repairable systems to predict the number of failures over time, conditional reliability, and failure rates
- Develop proficiency in the use of Reliasoft Weibull++ for Reliability analyses

Vladimir Todorov says

Marked by mistake that Module 2 is completed, now can’t go back to it and access the Lessons

Steven Wachs says

Vladimir,

I’m sorry about this trouble. Fred Schenkelberg should be able to correct this. He’s on US Pacific time zone so should see this in a few hours. Best, Steve

Vladimir Todorov says

Thanks!

Fred Schenkelberg says

Thanks for letting us know Vlad. You should be able to view lessons within a module that is marked complete – the issue this morning is the lessons were not associated with the course anymore, thus not available to view. I’m working on restoring the associations and starting an investigation on what happened to cause the problem.

Please do let us know if you notice any issues –

cheers,

Fred
