| INFORMATION TECHNOLOGY IN CIVIL AND STRUCTURAL ENGINEERING DESIGN Edited by: B. Kumar, I.A. MacLeod, A. Retik Paper VI.1 Design from Breakdowns: The Integration of Design and Diagnosis W.P.S. Dias Civil Engineering Department, University of Moratuwa, Sri Lanka Full Bibliographic Reference for this paper W.P.S. Dias, "Design from Breakdowns: The Integration of Design and Diagnosis", in B. Kumar, I.A. MacLeod, A. Retik, (Editors), "Information Technology in Civil and Structural Engineering Design", Inverleith Spottiswoode, Edinburgh, UK, pp 77-80, 1996. Abstract The complementarity between design and diagnosis is
highlighted, using Heidegger's ideas regarding
"breakdowns", Popper's advocacy of theory falsification and
Blockley's model of a reflective practice loop. The influence
of structural failures on structural design codes is discussed.
Product models, process models and expert systems are
proposed as information technology and artificial intelligence
tools that can enhance design. It is argued that the attributes
and structuring of these models and the relevance of the
expert system rules could be improved by incorporating
knowledge obtained from diagnosis of failures. However,
more work is required to develop systems that can transform
diagnostic data into design knowledge.
