News Item: exida Article on Cybersecurity Featured in Hydrocarbon Processing
An article on ICS cybersecurity written by Dr. William Goble is featured in the July 2018 issue of Hydrocarbon Processing. Unfortunately, nation states appear to be launching cybersecurity attacks on other nation states. In this “arms war,” some attacks have been focused on industrial control systems (ICS). Three of these…
Training Course: Practical Mechanical FMEDA with FMEDAx™
The FMEDA method was invented to predict failure rates for each failure mode of a device, subsystem, or component. The ”Practical Mechanical FMEDA with FMEDAx” course explains the FMEDA method, objectives, and output. In this course an example device FMEDA will be done showing the fundamental concepts including environmental profile…

Recorded Webinars: Using Manufacturer Warranty Failure Data (Not)
For decades manufacturers have been using their customer return data to estimate failure rates for their products. exida also uses this data but only for comparison and validation purposes. This webinar will show the result of several of our recent warranty failure calculations and the comparison to the corresponding FMEDA prediction for the same product. We will show how the data is useful for calibrating a component database. We will show why warranty data is not a useful method for realistic failure rates used for safety verification calculations.
