[mod.ai] Seminar - An Expert System for Building Layout

Steven.Minton@K.CS.CMU.EDU (11/19/86)

This week's seminar is being given by Robert Coyne and Tim Glavin.
As usual, Friday, 3:15 in 7220.

ABSTRACT:
We report on work in progress on a generative expert system for the design
of building layouts that can be adapted to various problem domains.  The
system does not reproduce the behavior of human designers; rather, it
intends to complement their performance through (a) its ability to
systematically search for alternative solutions with promising trade-offs;
and (b) its ability to take a broad range of design concerns into account.
Work on the system also aims at providing insights into the applicability of
artificial intelligence techniques to space planning and building design in
general.

Spacial relations between the objects to be allocated serve as basic design
variables which define differences between layouts.  They are represented by
a novel scheme, called an orthogonal structure, which allows us to enumerate
layouts in an abstract space, following a 'least commitment' strategy with
regard to details such as the dimensions of the objects.  The
representation, and the generator based on it, are general and flexible
enough to allow generation of layouts in various 'domains'.  The knowledge
required to distinguish good or 'best' layouts in particular domains is
located in special testers which are to be built up through the process of
'knowledge acquisition' as it typically occurs in the development of expert
systems.
