A Survey of Design Philosophies, Models, Methods and Systems

Abstract
The study of the design process, design theory and methodology has been a preoccupation of engineers, designers and researchers over the last four to five decades. As the end of this millenium is approached and with the renewed interest around the world in engineering design, it is fitting to examine the state of the art and current status of issues relating to design philosophies, theory and methodology. Over the last 40 years, many approaches to design have been put forward by various researchers, designers and engineers, both in academia and industry, on how design ought to and might be carried out. These proposals on design have tended towards what has come to be regarded as design philosophies, design models and design methods. The thesis of this paper is to discuss various aspects of generic research in design, within the above classifications in the light of the work that has been done in the last four decades. Discussions will focus on various definitions of design, design theory and methodology, the nature and variety of design problems, design classifications, philosophies, models, methods and systems.
