title	Development of a Knowledge-Based System for Structural Optimization
source	Dordrecht: Kluwer, 1988. pp. 17-24
summary	Optimization is a useful and challenging activity in structural design. It provides designers with tools for better designs while saving time in the design process. The features of conventional optimization tools are presented and their limitations are outlined. The impact and role of knowledge-based methodologies in structural optimization processes is discussed. Structural optimization involves a number of tasks which require human expertise, and are traditionally assisted by human designers. These include design optimization formulation, problem recognition and the selection of appropriate algorithm(s). In this representation and processing of constraints are crucial tasks. This paper presents a framework for developing a knowledge-based system to accomplish these tasks. Based on the needs and the nature of the optimization process, a conceptual architecture of an integrated knowledge-based system is presented. The structure and functions of various components of the system are described

title	A Model for Knowledge-Based Design Optimization [PhD dissertation]
source	Dept. of Architectural Science, University of Sydney
summary	Unpublished. CADLINE has abstract only. This dissertation is concerned with developments in design decision methodologies applied to computer-aided design. The major aim of this research was to design and develop a knowledge-based computer-aided optimization system that has the ability to emulate some of the human performances in design decision processes. The issues and problems involved in developing a knowledge-based system for design optimization are addressed. A knowledge-based methodology to aid design optimization formulation is investigated. The major issues considered include representation of design description, the variety of knowledge required for the formulation process, recognizing optimization formulations, and selection of appropriate algorithms. It is demonstrated that the knowledge-based control of numerical processes leads to efficient and improved decisions in design. In developing knowledge-based systems for computer-aided decision applications an effective human-machine interface is essential. A model for knowledge-based graphical interfaces is proposed. This model incorporates knowledge for graphics interpretation, extraction of features of graphics objects and identification of prototypical objects. An experimental system developed in Prolog and C is demonstrated in the domain of structural design. The system shows one way of combining knowledge-based systems technology with computer graphics and indicates how knowledge-based interfaces improve the system's interactive capabilities. Finally, the system, OPTIMA, is presented. The system is designed as an integrated knowledge-based decision system using frames, rule bases, menu inputs, algebraic computation and optimization algorithms. The system has been written in LISP, Prolog and C and implemented on SUN Microsystems workstations. The performance of the system is demonstrated using two example problems from the domains of structural and architectural design respectively. The knowledge-based approach to design optimization is shown to be considerably easier and more efficient than those using conventional programs.

title	Requirements for Developing an Information System for Architecture
source	CAAD futures ‘87 [Conference Proceedings / ISBN 0-444-42916-6] Eindhoven (The Netherlands), 20-22 May 1987, pp. 149-170
summary	This paper discusses possibilities of developing new tools for architectural design. It argues that architects should meet the challenge of information technology and computer-based design techniques. One such attempt has been the first phase of the development of an architectural design information system (ADIS), also an architectural design decision support system. The system should benefit from the developments of the artificial intelligence to enable the architect to have access to information required to carry out design work. In other words: the system functions as a huge on-line electronic library of architecture, containing up-to-date architectural design information, literature, documents, etc. At the same time, the system offers necessary design aids such as computer programs for design process, drawing programs, evaluation programs, cost calculation programs, etc. The system also provides data communication between the architect and members of the design coalition team. This is found to be of vital importance in the architectural design process, because it can enable the architect to fit in changes, brought about in the project by different parties. Furthermore, they will be able, to oversee promptly the consequences of changes or decisions in a comprehensive manner. The system will offer advantages over the more commonly applied microcomputer based CAAD and IGDM (integrated graphics database management) systems, or even larger systems available to an architect. Computer programs as well as hardware change rapidly and become obsolete. Therefore, unrelenting investment pressure to up-date both software and hardware exists. The financial burden of this is heavy, in particular for smaller architectural practices (for instance an architect working for himself or herself and usually with few or no permanent staff). ADIS, as an on-line architectural design aid, is constantly up-dated by its own organisation. This task will be co-ordinated by the ADIS data- base administrator (DBA). The processing possibilities of the system are faster, therefore more complex processing tasks can be handled. Complicated large graphic data files, can be easily retrieved and manipulated by ADIS, a large system. In addition, the cost of an on-line system will be much less than any other system. The system is based on one model of the architectural design process, but will eventually contain a variety of design models, as it develops. The development of the system will be an evolutionary process, making use of its users' feed-back system. ADIS is seen as a step towards full automation of architectural design practices. Apart from being an architectural design support system, ADIS will assist the architect in his/her administrative and organisational activities.

title	Computer-Aided Diagramming and the `Generator-Test' Cycle
source	1988. 22 p.: ill. includes bibliography
summary	Simon's `generator-test' model is both a metaphor and a literal prescription for the organization of computer systems for designing. In most approaches to computer-aided design, one side of the cycle - generating or testing - is reserved to the human designer, the other side delegated to the computer. A more comfortable and comprehensive approach is to support switching these roles between designer and computer. This approach underlies a prototype system for computer-aided diagramming, the CBD (Constraint-Based Diagrammer). Diagramming is an important design activity, especially in preliminary design, as diagrams play a pivotal role between graphic and symbolic knowledge. Diagrams as a medium of knowledge representation and as means of inference have an ambivalent status in the generator-test model; they may serve either purpose. Examination of CBD sheds some light on Simon's model and on the requirements for sharing generating and testing with computational design tools

title	Concept Design Games
source	Design Studies, Volume 9, Number 3, 1988, pp. 12-23
summary	This paper describes our work on using games as a tool for research in design theory and methods. Games offer a means of isolating certain aspects, or concepts, of designing for purposes of scrutiny. A game provides an environment for a group of players, acting with individual goals and a shared program, to make and transform complex configurations, free of functional requirements. Adjusting game parameters emphasizes different concepts. We have developed nine games that explore a variety of concepts of general interest to those concerned with organizing physical configurations. Beyond these particular concepts, we argue that games are a useful way to couch studies in design theory and methods.

title	An Evaluation of Programming Languages and Language Features for Engineering Software Development
source	International Journal of Engineering with Computers. Springer-Verlag, 1988. vol. 3: pp. 183-199
summary	Also published as 'Procedural Programming Languages for the Development of CAD and CAE Systems Software,' in the proceedings of ASME International Conference on Computers in Engineering (1987 : New York, NY). The scope of engineering software has increased dramatically in the past decade. In its early years, most engineering applications were concerned solely with solving difficult numerical problems, and little attention was paid to man- machine interaction, to data management, or to integrated software systems. Now computers solve a much wider variety of problems, including those in which numerical computations are less predominant. In addition, completely new areas of engineering applications such as artificial intelligence have recently emerged. It is well recognized that the particular programming language used to develop an engineering application can dramatically affect the development cost, operating cost. reliability, and usability of the resulting software. With the increase in the variety, functionality, and complexity of engineering software, with its more widespread use, and with its increasing importance, more attention must be paid to programming language suitability so that rational decisions regarding language selection may be made. It is important that professional engineers be aware of the issues addressed in this paper, for it is they who must design, acquire, and use applications software, as well as occasionally develop or manage its development. This paper addresses the need for engineers to possess a working knowledge of the fundamentals of computer programming languages. In pursuit of this, the paper briefly reviews the history of four well known programming languages. It then attempts to identify and to look critically at the attributes of programming languages that significantly affect the production of engineering software. The four procedural programming languages chosen for review are those intended for scientific and general purpose programming, FORTRAN 77, C, Pascal, and Modula-2. These languages are compared and some general observations are made. As it is felt important that professional engineers should be able to make informed decisions about programming language selection, the emphasis throughout this paper is on a methodology of evaluation of programming languages. Choosing an appropriate language can be a complex task and many factors must be considered. Consequently, fundamentals are stressed

title	A Computational Tool for Evaluation of Seismic Performance of RC Buildings
source	February, 1990. [1] 15 p. : ill. graphs, tables. includes bibliography: p. 10-11
summary	Recent events have demonstrated the damaging power of earthquakes on structural assemblages resulting in immense loss of life and property (Mexico City, 1985; Armenia, 1988; San Francisco, 1989). While the present state-of-the-art in inelastic seismic response analysis of structures is capable of estimating response quantities in terms of deformations, stresses, etc., it has not established a physical qualification of these end-results into measures of damage sustained by the structure wherein system vulnerability is ascertained in terms of serviceability, repairability, and/or collapse. An enhanced computational tool is presented in this paper for evaluation of reinforced concrete structures (such as buildings and bridges) subjected to seismic loading. The program performs a series of tasks to enable a complete evaluation of the structural system: (a) elastic collapse- mode analysis to determine the base shear capacity of the system; (b) step-by-step time history analysis using a macromodel approach in which the inelastic behavior of RC structural components is incorporated; (c) reduction of the response quantities to damage indices so that a physical interpretation of the response is possible. The program is built around two graphical interfaces: one for preprocessing of structural and loading data; and the other for visualization of structural damage following the seismic analysis. This program can serve as an invaluable tool in estimating the seismic performance of existing RC buildings and for designing new structures within acceptable levels of damage

title	Chips, chunks and sauces
source	International Journal of Design Computing, 1, 1997 (Editorial)
summary	I am sure there is an art in balancing the chunks to use with your chips. Then there is the sauce that envelops them both. I like my chips chunky and not too saucy. Not that I am obsessed with food but I don't think you can consider design computing without chunks. It's the sauce I'm not sure about.The chunks of which I write are not of course those in your salsa picante but those postulated by Chase and Simon (1973) reflecting on good chess players; the chunks of knowledge with which an expert tackles a problem in their domain of expertise. The more knowledge an expert has of complex and large configurations of typical problem situations (configurations of chess pieces), the greater range of solutions the expert can bring a wider to a particular problem. Those with more chunks have more options and arrive at better solutions. In other words, good designs come from having plenty of big chunks available. There has been a wealth of research in the field of computer-supported collaborative work in the contexts of writing, office management, software design and policy bodies. It is typically divided between systems which support decision making (GDSS: group decision support systems) and those which facilitate joint work (CSCW: computer-based systems for co-operative work) (see Dennis et al. (1988) for a discussion of the distinctions and their likely convergence). Most implementations in the world of design have been on CSCW systems, few have looked at trying to make a group design decision support system (GDDSS?). Most of the work in CSCD has been grounded in the heritage of situated cognition - the assumption that collaborative design is an act that is intrinsically grounded in the context within which it is carried out, that is, the sauce in which we find ourselves swimming daily. By sauce, therefore, I am referring to anything that is not knowledge in the domain of expertise, such as modes of interaction, gestures, social behaviours.

summary	Much of the building designer's time is taken up correlating the various sources of information so as to incorporate it in the design within a limited time span. The building information service should be able to provide him or her by the up-to-date information in a user friendly format. Optical disc technology makes it possible to combine different forms of building data into images which can be mass stored and randomly accessed on a single disc, with the minimal response time by personal computer or CAD- workstation. In this paper the use of various forms of optical disc technology in construction industry and the prototype video disc produced by VTT are described.

title	Digital Image: A Bridge Towards Mental Images?
source	CAAD futures ‘87 [Conference Proceedings / ISBN 0-444-42916-6] Eindhoven (The Netherlands), 20-22 May 1987, pp. 209-216
summary	How we see things depends on our education and our cultural pre-suppositions. This does not allow to convey some logical form, but nevertheless makes possible a more global and less formalized understanding of the objects, their environment and their physical proprieties. In architecture, the digital image acts according to two directions: (-) representation: the fine images are a means of communication between the different parties implementing building projects. (-) modelization: in addition to its iconic qualities the layers of different models simulate the most different aspects of the ,image and the environment characteristics. // At this level our vision is directly concerned with the design of the studied object; it acts both in the design process and in the expression of our conceptual images. How does modelization work? Infographical representation deals with a more or less schematic and conceptualized world the reading of which is more typified than particularized. It deals with a schematization nearly "ideographical" of the mental image thus is produced "synthetism", a neologism similar to such expressions as realism or abstractionism.

summary	Passive solar energy design is not an exact science in which a set of analytical procedures can be followed to produce results. Rather it depends heavily on subjective parameters and experience collected over time which is heuristic by nature. At present this knowledge is available in books but while this knowledge is comprehensive, it is unstructured and not always easy to make use of. A computer-based system allows for flexible interactive dialogue and for the incorporation of analytical procedures which may be required. This paper describes work on SOLAREXPERT, a prototype expert system to aid designers in passive solar energy design for single dwellings. The system operates at a strategic level to provide basic advice on the form of construction and types of passive solar systems and at a spatial zone level to provide more detailed advice on sizes and materials. It allows for modification of the information entered so that users may explore several possibilities

summary	--- Also printed in 1989 Civil Engineering Systems 6(1&2):11-20. Engineering is concerned with much more than calculation and numeric analysis. It is concerned with ideas, concepts, judgement and deploying experience which cannot be represented numerically. All of these appear to be outside the realm of traditional engineering computing. Engineers make use of knowledge about objects, events and processes and make declarative statements about them which are often written down symbolically. These limitations of traditional computing in civil engineering can be overcome by expert systems. In this paper a number of expert systems dealing with analysis, design and knowledge acquisition in the field of civil engineering are presented

summary	It is the impact of the new media upon the way we view, model, and evaluate our architectural work that may change architecture and architectural education. Work by the authors and Filez Ozel with their students at the New Jersey School of Architecture has integrated microcomputer graphics into the school's mainstream design curriculum. The mechanical means have been two aging off the shelf software system- one that first creates wire-frame models and another that 'paints' them to create solids, as well as draw in a more freehand fashion. However the models were achieved, the results point to profound changes in the way that future architects can view the design process
