Supporting engineering design using knowledge based systems technology with a case study in electricity distribution network designMcDonnell, Janet Theresa January 1994 (has links)
This thesis explores the architectural requirements of engineering design support systems based on knowledge based systems technology. The exploration is based on an understanding of the nature of designing as a professional activity and on the extent to which designers' competence can be modelled. Attention is focused on certain salient aspects of designers' competent behaviour. The theoretical study leads to the specification of requirements to be satisfied by a knowledge based system which will support designers in their professional setting and to the proposal of some knowledge based system components which will meet the requirements identified. The theoretical aspect of the thesis is complemented by a case study based on a designer of high voltage electricity distribution networks. The case study illustrates the theoretical component of the thesis and the methodological basis for the work. The practical realizability of the components of the knowledge based systems architecture proposed are demonstrated using the results of the analysis of the knowledge elicited in the case study without prejudicing the general applicability of the ideas. An object-oriented knowledge engineering software development environment is used to demonstrate how some components of the design situation represented can be implemented.

Computer aided architectural evaluation and design : a cost modelling experimentBelhadj, Tami A. January 1989 (has links)
This dissertation addresses the problem of Computer Aided Architectural Evaluation and Design, with particular reference to building cost evaluation and cost modelling. It identifies the lack of building evaluation tools in the CAAD environment, and suggests an integrated approach to building modelling and cost modelling. The interaction of elemental and spatial descriptions of a design solution is considered as an original contribution to the field of computer aided building modelling and evaluation. It demonstrates the potential of CAAD and Bills of Quantities intergration to give an extra dimension to cost modelling at early design stages. Essentially, this research project advocates a larger overlap in the use of computers for the generation and evaluation of design. It asserts that any computer aided solution evaluation system must be able to converse with the designer during the highly integrated iteration of briefing, analysis, synthesis and evaluation stages of design. A working example is produced after software specification and implementation, to demonstrate to possibilities and/or limitations of such an approach.

A knowledge based support tool for the early stages of electronic engineering designScothern, Dean Grant Curtis January 1991 (has links)
A desire to produce a design support system for the early stages of electronic engineering design, has led to the conception of the Plymouth Engineer's Design Assistant (PEDA), pulling together experience from the three fields of computing, psychology and electronic engineering. The basic emphasis of this tool has been to use psychological techniques to analyze the cognitive aspects of designers in action and then make recommendations for design tool improvement. The results of the complementary psychological research, and other relevant literature are examined and potential avenues to realizing an improving design explored. A new idealized abstract representation of early electronic engineering is proposed, which is more in line witli the cognitive needs of designers, thus enabling the production of more capable design tools. The main points of the representation are discussed, and comparisons with other approaches and tools drawn. The abstract representation is then taken and used to form a specific implementation as the core to the PEDA tool. An overview of the PEDA tool is given, followed by a discussion regarding the important aspects of the implementation. Important issues and problems raised during the course of the research are discussed, together with suggestions for future work.

A specification for a next generation CAD toolkit for electronics product designCulverhouse, Philip Frederick January 1993 (has links)
Electronic engineering product design is a complex process which has enjoyed an increasing provision of computer based tools since the early 1980's. Over this period computer aided design tool development has progressed at such a pace that new features and functions have tended to be market driven. As such CAD tools have not been developed through the recommended practise of defining a functional specification prior to any software code generation. This thesis defines a new functional specification for next generation CAD tools to support the electronics product design process. It is synthesized from a review of the use of computers in the electronics product design process, from a case study of Best Practices prevalent in a wide range of electronics companies and from a new model of the design process. The model and the best practices have given rise to a new concept for company engineering documentation, the Product Book which provides a logical framework for constraining CAD tools and their users (designers) as means of controlling costs in the design process. This specification differs from current perceptions of computer functionality in the CAD tool industry by addressing human needs together with company needs of computer supported design, rather than just providing more technological support for the designer in isolation.
