Has anyone tried to apply autocorrelation to the mathematical
measurement of dissonance?

http://en.wikipedia.org/wiki/Autocorrelation

This line is intriguing

"Autocorrelation is a mathematical tool for finding repeating
patterns, such as the presence of a periodic signal which has been
buried under noise, or identifying the missing fundamental frequency
in a signal implied by its harmonic frequencies."

I'm not clear exactly how to apply it to the above problem but as I
said it is intriguing

Yes. Autocorrelation models have been a major pillar
of psychoacoustics since Licklider 1951.
