Abstract
This work addresses three issues in intelligent tutoring systems.
First, how to explain and illustrate the functioning of physical
devices. This capability is useful for understanding and using past designs.
The second issue is how to illustrate and explain the reasoning of an
expert designer. This capability is often required for supporting learning by
observation. Finally, might the same kinds of representations and
processes support these two capabilities? This thesis explores how
Structure-Behavior-Function models of physical devices and
Structure-Behavior-Function meta models of an autonomous design system
help to address these issues. The Structure-Behavior-Function model of
a device (or a system) explicitly specifies its structure, its
function and its internal behaviors that map its structure into its
function. This research has resulted in a system called Canah-chab
that provides an interactive graphical interface to an autonomous
design system called Kritik2. It illustrates and explains both the
physical devices in Kritik2's memory and the processes by which it
generates new design. In addition, Canah-chab enables a user to
navigate Kritik2's memory and access the stored designs.
