    Work in artificial intelligence has shown that rule induction is a useful aid to knowledge acquisition but that its general applicability is limited. In particular, induced rules can be difficult to understand and hard to modify. This paper describes a computer program to generate knowledge bases from examples in a form which can be interpreted either as a set of rules or as an inference network. ... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (556 KB)

    The databases of contemporary CAD systems cannot be used to drive most CAE and CAM systems in an automated manner since CAD systems do not produce a complete product definition. The information that is supported is in the form of low-level details, from which higher-level information such as form features cannot be obtained easily.

    Software engineers responsible for producing CAE tools have been relying, to the detriment of their product, on primitive design tools. The roots of this puzzle lie in the short history of software engineering as a discipline and the amount of foundation work that has had to be done to establish a proper base from which to build. Sufficient groundwork has now been done to allow software engineers ... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (3472 KB)

    The design of LSI/VLSI circuits requires a simple but formalised methodology. This paper outlines a high-level design methodology based on the use of Petri nets. The system is assumed to consist of communicating modules that are synchronised for the purpose of passing data but which otherwise operate concurrently. The description of the net in both graphic and text form is considered. View full abstract»

    Integrated CAE implies the intimate interlinking of many diverse engineering systems. This could be achieved on a piecemeal basis with data distributed over the various systems and managed in local databases. However, a much more elegant solution for system integration, and certainly the only viable long-term one, is through the medium of a central engineering database. This database must store al...
