| summary |
It seems by now fairly accepted by many researchers in the field of the Computer
Aided Design that the way to realise support tools for the architectural design is by
means of the realisation of Intelligent Assistants.
This kind of computer program, based on the Knowledge Engineering and machine
learning, finds his power and effectiveness by the Knowledge Base on which it is
based.
Moreover, it appears evident that the modalities of dialogue among architects and
operators in the field of building industry, are inadequate to support the exchange of
information that the use of these tools requires. In fact, many efforts at international level are in progress to define tools in order to
make easier the multiple exchange of information in different fields of building
design. Concerning this point, protocol and ontology of structured information
interchanges constitute the first steps in this sense, e.g. those under
standardisation by ISO (STEP), PDT models and Esprit project ToCEE.
To model these problems it has brought forth a new research field: the collaborative
design one, an evolution of distributed work and concurrent design. The CAAD Laboratory of Dipartimento di Architettura and Urbanistica per
l'Ingegneria has carried out a software prototype, KAAD, based on Knowledge
Engineering in the fields of hospital building and of building for aged people.
This software is composed by an Interface, a Knowledge Base, a Database and
Constraints.
The Knowledge Base has been codified by using the formal structure of frames,
and has been implemented by the Lisp language. All the elements of KB are objects |
