Modeling Creativity and Knowledge-Based Creative Design


Over the last decade research into design processes utilizing ideas and models drawn from artificial intelligence has resulted in a better understanding of design -- particularly routine design -- as a process. Indeed, most of the current research activity directly or indirectly deals only with routine design. Not surprisingly, many practicing designers state that the level of understanding represented by these models is only of mild interest because they fail to embody any ideas about creativity.

This volume provides a set of chapters in the areas of modeling creativity and knowledge-based creative design that examines the potential role and form of computer-aided design which supports creativity. It aims to define the state-of-the-art of computational creativity in design as well as to identify research directions. Published at a time when the field of computational creativity in design is still immature, it should influence the directions of growth and assist the field in reaching maturity.


Design is one of the most significant of the purposeful acts of human beings. It creates a new, artificial world for us to inhabit and as such changes us all. The burgeoning ability to model and implement design processes as reasoning systems, making use of artificial intelligence research and techniques, has given new impetus to the study of design theory and methodology.

There is general acceptance that design activities can be categorized as being either routine or nonroutine. The distinction being drawn by this categorization is to separate design processes, in which the functions (i.e., goals or requirements) are known as are the available structures and the processes which map function to structure, from those in which one or more of function, structure or mapping is not known a priori. This allows us to begin to address one of the fundamental issues in design: that of creativity. Dictionary definitions of creativity are too imprecise to provide either a formal or operational definition that is useful.

An operational definition of creativity in design that has been found to be useful states that creativity involves the introduction of new variables into the design process, variables which were not originally considered by the designer or design system. Such a definition begs important questions related to the value of artifacts designed by such processes.

The problem-solving paradigm used in artificial intelligence appears to preclude the introduction of new variables because it was initially concerned with finding ways of achieving predefined goals from a specified initial state while passing through known states in some state-space representation.

Because creative design involves exploration (i.e., finding new goals, new states, and new state transition processes), it would appear that the original . . .
