I looking for information on an expert system called MDL/MAD for large-
scale software design.  I've heard a little bit about it already.  It has
about 1500 rules concerned with relationships among design data, the design
decision-making procedure and the format for expressing design information. 
It has been claimed to reduce design errors by 40% and specification/
correction time by 80%.  It is still under development at Hitachi's Software 
Development Laboratory and is two years away from commercial release.  

The questions are:  What does it really do and how does it work?

I would also be interested in related systems ICAS (Hitachi), DEA/I (NEC)
and SDEM/SDSS (Fujitsu).
