What is WeiBayes Analysis?
podcast episode with speaker Chris Jackson
Some of us might have heard of the Weibull distribution. Some of us might have heard about Weibull analysis. Weibull analysis uses the Weibull distribution to help us visualize failure data in a really useful way. We can see' if our product is wearing out. We can see if our product is wearing in. We can estimate how many things will have failed by certain times. We can do all manners of other wonderful reliability engineering' things through Weibull Analysis. But then there is WeiBayes Analysis.' It combines Weibull and Bayesian analysis ( I know that doesn't mean much to most people). It can be really useful if we know how' something we are testing fails. Because if we do, then we can essentially feed a certain parameter into the analysis to help it on its way. This means that we don't need as much data (always a good thing in reliability engineering). But there are quite a few catches. Interested in learning about Weibayes analysis? Join us for this webinar.

Collecting and Analyzing Your Field Data
Let's explore where the data comes from and how to prepare for analysis. Plus, let's discuss some ways to look at your data initially.

Time to Failure Data Analysis for Your Factory Equipment
For repairable items, the mean cumulative function and associated plots provide you with an estimate of the effectiveness of your repairs.

Reliability Data
We will discuss the pros and cons of various sources. Plus, let's examine a few ways to use simulations or models.

Fundamentals of Weibull Analysis
The Weibull distribution is a versatile tool to analyze time to failure data. Like any tool, it could be wielded well or not so well.

Fundamentals of Field Data Analysis
The design is done, the assembly process is working, now we can focus on answering the question: is the product hitting reliability targets?

Weibull Probability Plotting
Data is only as useful as the information you derive. So would you like to take your Weibull probability plotting skills to the next level?
