Subject: Markov Modeling and European Reliability
We are working with several customers from Europe that are starting to ask for some analysis that is unique. Such things as Markov Modeling, FMECA with that modeling and Accelerated life testing for determining in use MTBF. This is usually above what US companies are asking. My question is this. Is the European standards (what are they) different that US standards (what are they) for commercial industry? I am begining to suspect that Europe and the US are diverging with regards to how we evaluate a product and required or commonly asked for reliability results.

It also depends on what business/market they are in. It is not uncommon for commercial telecom and networking companies to use Markov models to solve for availability and MTBCF. Likewise, for power supply companies to use FMECA and fault-tree analysis. The real add in a design for reliability program is using these tools to improve the design as the product is being developed.
