A Phase Advisor for Industrial Chemical Engineering

A recent conversation with a chemical engineer at MIT led me to remember an expert system a member of our AI group, Dan T. Davis wrote in the late 1980s.  It was meant to provide advisory consulting in the surfactant chemistry space. And was based on the expertise of  employee Bob Laughlin, author of "The Acqueous Phase Behavior of Surfactants".   It was based on methods of knowledge engineering and rule based expert systems.  I am doing some additional digging on the methods and history of this system and will post them here.    Anyone have specific examples of use and methods, contact me.
