A critical review of General Design Theory
نویسنده
چکیده
This study is a critical review of General Design Theory (GDT), a mathematical theory of design. The study reviews the assumptions (axioms) and predictions (theorems) of GDT with respect to design and illustrate them with a simple example. The scope of GDT with respect to design, the guidelines it provides for building computer-aided design (CAD) systems, and the possibility of implementing these guidelines are examined. GDT assumptions are too restrictive to apply directly to design, and several potential avenues for modifying the theory to attempt to broaden its scope are discussed. Nevertheless, these modiications may not lead to proving strong predictions about design. Treating GDT as a model, rather than as an accurate reeection of design, allows treating the guidelines as hypotheses to be tested empirically. The paper discusses these guidelines and some experimental implementation that embody some of them.
