Your Reliability Engineering Professional Development Site
In the article Calculating Network Reliability the lack of published analytical solution for dual-ring network reliability was highlighted.  This article provides a neat solution and further challenges readers to offer their proof or prior publication reference.  The solution and the author’s general proof will be presented at RAMS 2020.
I have worked in the field of reliability for a good many years. I have presented both beginner and advanced reliability engineering courses. I have even read several books. 🙂 But, across all this, component redundancy has never been explained beyond simple serial and parallel configurations.
So, it was a shock to my system to be presented with a scenario that couldn’t be solved using a simple parallel system.
My previous work had challenged me only as far as:
But now I was being challenged by a network that was none of these.
