Hello Designers:

I am a researcher working in the field of uncertainty quantification, developing tools that propagate uncertainty through a system. Whenever I make a presentation I claim that one has uncertainties in every design because of tolerances and these lead to uncertainties in performance characteristics.

I would like to know how "you" (a designer) would feel if I deliver a tool that takes your design with tolerances and give you the bounds on the response ( stress, displacement, frequency, etc.) at the click of a button. And tell you the probability of failure of that component.

Would you like to have this tool so that you can work on your design, control parameters to have a safer design even before it is sent for testing.

Any comments from the designers out there would help me understand the real need for this type of work. It would not only help me but many researchers like me would lookinto this when I mention it in my future conferences.

Thank you in advance for any input that you might provide.
