title The Studio CTH-A and the Searching Picture
source Endoscopy as a Tool in Architecture [Proceedings of the 1st European Architectural Endoscopy Association Conference / ISBN 951-722-069-3] Tampere (Finland), 25-28 August 1993, pp. 129-140
summary What happens during an architect’s search for the best solution? How does he (or she) begin, which tools are chosen, what happens when he comes to a standstill? The activities – sketching, discussions with other people, making models, taking walks to think, visits to the library, etc? What is an ordinary procedure and what is more specific? Do the tools have an impact on the final solution chosen? What happens during periods of no activity? Are they important? In which fields of activities are signs of the searching process to be found? In other words — what is the process of creative thinking for architects? Mikael Hedin and myself at Design Methods, Chalmers University of Technology, have started research into architects’ problem-solving. We have finished a pilot study on a very experienced architect working traditionally, without Cad (”The Bo Cederlöf Case”). We have started preliminary discussions with our second ”Case”, an architect in another situation, who has been working for many years with Cad equipment (Gert Wingårdh). For our next case, we will study a third situation – two or more architects who share the responsibility for the solution and where the searching is a consequence of a dialogue between equal partners. At present, we are preparing a report on theories in and methods for Searching and Creativity. I will give you some results of our work up till now, in the form of ten hypotheses on the searching process. Finally, I would like to present those fields of activity where we have so far found signs of searching. Our approach, in comparison with earlier investigations into searching (the most respected being Arnheim’s study on Picasso’s completion of the Guernica) is to collect and observe signs of searching during the process, not afterwards. We are, to use a metaphor, following in the footsteps of the hunter, recording the path he chooses, what marks he makes, what tools, implements and equipment he uses. For practising architects: a better understanding of what is going on and encouragement to try new ways of searching, for architectural students: better preparation and training for problem solving. It all began while we compared the different objects in our collection of sketches at the Chalmers STUDIO for Visualisation and Communication. (For some years, we have been gathering sketches by Alvar Aalto, Jorn Utzon, Ralph Erskine, Erik and Tore Ahlsén, Lewerenz, Nyrén, Lindroos, Wingårdh and others in a permanent exhibition). We observed similarities in these sketches which allowed us to frame ten hypotheses about the searching process.

title Spatial Perception in Virtual Environments: Evaluating an Architectural Application
source IEEE Virtual Reality Annual International Symposium, 1993, Seattle
summary Over the last several years, professionals from many different fields have come to the Human Interface Technology Laboratory (H.I.T.L) to discover and learn about virtual environments. In general, they are impressed by their experiences and express the tremendous potential the tool has in their respective fields. But the potentials are always projected far in the future, and the tool remains just a concept. This is justifiable because the quality of the visual experience is so much less than what people are used to seeing; high definition television, breathtaking special cinematographic effects and photorealistic computer renderings. Instead, the models in virtual environments are very simple looking; they are made of small spaces, filled with simple or abstract looking objects of little color distinctions as seen through displays of noticeably low resolution and at an update rate which leaves much to be desired. Clearly, for most applications, the requirements of precision have not been met yet with virtual interfaces as they exist today. However, there are a few domains where the relatively low level of the technology could be perfectly appropriate. In general, these are applications which require that the information be presented in symbolic or representational form. Having studied architecture, I knew that there are moments during the early part of the design process when conceptual decisions are made which require precisely the simple and representative nature available in existing virtual environments.

title Designing the Future: The Computer Transformation of Reality
source Thames and Hudson, Hong Kong
summary A coffee table book on computer applications? Well, yes, because it does deal largely with matters of graphic design in architecture, fashion and textiles, painting, and photography; but it also has items which might be of interest in its sections on digital publication, typography, and electronic communication in general. It also seeks to discuss the way in which these applications may force us to change the way we think. Robin Baker writes in an unfortunately stiff and abstract manner about the impact computer programmes have had on the world of art and design, but the graphic images and extended picture captions help to keep the reader awake - even though the main text sometimes disappears for two or three double page spreads on end. There are also smatterings of pretentious art-world-speak about 'solving certain spatial problems' (in the design of curtain fabrics or teapots) and the introduction (inevitable?) of new jargon: 'shape grammar'(a list of so-called shape 'rules'), 'repurposing' (putting somebody else's work to new use) and 'genetic algorithms' (sculptural designs based on re-processed organic shapes - most of which look like stomach tumours). In his favour, Baker very generously credits students and commercial designers who have produced the effects he describes and illustrates so well. For writers, he sketches in the possibilities of Hypertext and Hypermedia and points to the future of Hyper publishing which he (and Rupert Murdoch)believes will be with us before the end of the century. He seems to have a good oversight of what is possible and practicable - though one wonders how up-to-date the view is when his book may have begun its life anything up to three years ago. He usefully points out that much new technology exists in or drags along with it the forms of earlier periods - so that in an age of electronic communication we still have printed books as a dominant cultural form. Maybe this is as it should be - but Baker makes a persuasive case for the claim that All This is Going to Change.

title SOME EPISTEMOLOGICAL CONCERNS REGARDING ARTIFICIAL INTELLIGENCE AND KNOWLEDGE-BASED APPROACHES TO ARCHITECTURAL DESIGN - A RENEWED AGENDA
source Education and Practice: The Critical Interface [ACADIA Conference Proceedings / ISBN 1-880250-02-0] Texas (Texas / USA) 1993, pp. 155-162
doi https://doi.org/10.52842/conf.acadia.1993.155
summary It has been noted that designers - when confronted with computers - have, by and large, refused to accept the introduction of apparently new design methodologies, and it has been speculated that this is the result of a failure of those methodologies to address the cognitive processes which take place in the course of designing. This position is somewhat suspect in that such innovations as computer-aided drafting -which also fail to recognize these processes have been widely accepted. It is perhaps more likely that the lack of acceptance results from a perception on the part of designers that the new methodologies either do not reflect some or all of those concerns that designers consider fundamental to design, or that they actively interfere with the designer's ability to accomplish what he/she sees as the goals of design. Given that the application of artificial intelligence and related work to architecture is still in its infancy, all of this suggests the need for a reassessment of the role of computing in design in order to clarify and strengthen those roles deemed appropriate.

Two approaches to the integration of artificial intelligence and knowledge-based systems into architectural design practice are currently dominant. One attempts to create systems which can on their own produce designs, the other provides intelligent support for those doing design. It was, in part, the recognition of limitations in the ability of traditional CAD systems and building modelers to reflect what designers actually do that led to explorations into the idea of intelligent assistants. Development of such assistants was aided by research into the act and process of design through protocol and other studies. Although some work is currently being done in the development of artificial intelligence and knowledge based applications in architecture, and work continues to be done on the study of design methodologies, the bulk of available information in each of these areas remains in the realm of design disciplines related to but outside of architecture and do not reflect the explicit role of architectural design in the embodiment and expression of culture.

The relationship of intelligence to culture has resulted in some skepticism regarding the ultimate capacity of neural nets and symbolically programmed computers in general. Significant work has been done questioning the rational tradition in computer development for its failure to address phenomena which are not easily subject to scientific analysis. Further skepticism regarding the role of artificial intelligence and knowledge-based or expert systems in architectural design has been emerging recently. Such criticism tends to focus on two issues: the nature of drawing as an activity which involves both the generation and interpretation of graphic artifacts, and the nature of the human designer as an active agent in the design process.

title Grammatical programming : an algebraic approach to the description of design spaces
source Carnegie Mellon University
summary The intuitiveness of spatial grammars makes them an attractive method of describing spaces of design. But grammars suffer from several inadequacies that limit their usefulness in design practice: (1) they cannot describe spaces of parametric, constrained designs, (2) they provide no control mechanisms for sequencing sets of rules, (3) they provide no 'subroutines' for dealing with complexity, and (4) they do not accommodate transformation mechanisms other than the rewrite rule. All of these inadequacies my [sic] be remedied by embedding grammars in a larger framework of nondeterministic functional programming, a paradigm we call 'grammatical programming.' In grammatical programs, rewrite rules are obtained from arbitrary nondeterministic functions by means of a 'rewrite closure' operator. Both rules and the designs they operate upon may be parametric and have attached constraints, permitting grammatical programs to describe spaces of parametric, constrained designs. Rewrite rules, and more generally, nondeterministic functions, are combined into compound functions by means of the operators of a control algebra, which provides functional composition, union, iteration, and a type of negation called 'failure.' The resulting modularity permits design space descriptions to be constructed, tested, and debugged piecewise, and to draw upon libraries of standard, debugged grammatical components. We begin this dissertation with an informal introduction to grammatical programming. We then give a formal, implementation-independent semantics of grammatical programs similar to the semantics of stratified logic programs. We discuss the implementation of a prototype compiler/interpreter and present case studies of the use of the prototype in describing spaces of rectangular dissections and a style of early Gothic traceries. We conclude with a discussion of lessons learned from the case studies and an agenda of further research necessary to make grammatical programming a useful tool in design practice.

title The role of visual emergence in collaborative design
source Computational Support for Distributed Collaborative Design, Key Centre of Design Computing, University of Sydney, pp. 103-115
summary There are two fundamental approaches to the use of computers to support collaborative design: (i) to use the computer as a device which increases the efficiency of what designers could do previously, and (ii) to use the computer as an active device which allows designers to do what they could not readily do previously. // This paper is concerned with the latter approach by introducing the concept of visual or graphical emergence as one form of collaboration at a distance that can not readily be carried out without the aid of the computer.

title Looking into Endoscopy - The Limitations of Evaluation in Architectural Design

summary The means available to architects in their age-old task of creating (most usually, though not necessarily) buildings that do not yet exist (ie. virtual realities), can be seen as falling into two groups. Those that help us develop architectural ideas (exploring), and those that help us evaluate or test them (illustrating). In the former category, we have, for instance, the ”drawing on the back of the envelope”, the discursive brainstorm, and the design ”conversation with ourselves via paper and pencil” (the drawing strikes back). In the latter, we may include physical model building, careful (projective) drawing (including drawings that are instructions for making), mathematical and design science modelling and calculating, visualising techniques such as the rendered perspective, most CAD (computer aided design) work and architectural endoscopy. These techniques may be thought of in two ways, as Bosselman reported: the explanation (eg. the organisational plan) and the experience (eg the ”photo-realistic” perspective). Attached to these we have rules for success, such as those of ”style” (in the broad sense of the personal style that allows us to assume that we have answers to problems that have yet to appear). It should be clear even from the list above that there are many more techniques and technologies for evaluation (illustration) than for exploration (design): such is the mystery of design. It is the primary purpose of this paper to invite those involved in providing the enormous effort that has gone into making such techniques for illustration — evaluation — to consider how their efforts help with that other, and crucial, area — that of exploring: and to redress some of the balance of that effort towards exploration. For it occurs to me (as a teacher of architecture), that evaluation does not provide a course for action — it merely helps us determine what may be wrong (according to some criteria with which we choose not to argue). And, no matter how right or wrong a design may be, knowing that it is wrong doesn’t help us either modify it, or find a better initial idea. It only tells us we are not right — always assuming the evaluative model is correct; perhaps.

doi https://doi.org/10.52842/conf.ecaade.1993.x.r9o
summary The field of Computer-Aided Architectural Design (CAAD) is composed of two main threads of development, Academic and Professional, and can be described in three decades, which correspond roughly with three generations of computer systems. This paper presents a brief description of the entire period of school- and practice-based research and development on the applications of computers in Architectural design, and shows how these efforts have and have not been relevant to students' future experiences. Educators must take a fresh look at their current courses and research programs to make sure that they are relevant in the rapidly changing world of professional practice. With limited human and financial resources at most institutions, it is critical to make the best possible choices for the immediate and long-term benefit of today's students. While it is not appropriate for Schools of Architecture to operate strictly at the behest of the profession, we must prepare our students for the world in which they will practice. Therefore, I believe that it is important for the faculty at each School to consider the following questions: (-) Are our students prepared to enter realistic positions as soon as they graduate? (-) Do they have the background necessary to use computers effectively in the future? (-) Do our research efforts have results that designers are likely to use today or any time soon to make better buildings or to make buildings better?

doi https://doi.org/10.52842/conf.ecaade.1993.x.g6a
summary It is not always obvious to Architecture students how database and spreadsheet programs can be used as a design aid. At Liverpool we discuss and illustrate the use of such programs as part of a compulsory first year course, but it is clear that students on the course find it much easier to appreciate the usefulness and relevance of the drawing and modelling programs which they look at than other elements of the course, such as database handling. What we plan to do for the academic year 1993/4 is to illustrate how a (relational) database can have the potential to aid design and to analyse the design process for real projects. The particular example which we will be describing is that of the design of Health Centres in the UK.

title A model appraising the performance of structural systems used in sports hall and swimming pool buildings in greece
source Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary The selection of the best performing structural system (among steel, timber laminated, concrete, fabric tents) for medium span (30-50m) sports halls and swimming pools in Greece formed the impetus for this research. Decision-making concerning selection of the structural system is difficult in this sector of construction, as was explained in the "Long Span Structures" conference (November 1990, Athens. Greece). From the literature it has been found that most building appraisals end up at the level of data analysis and draw conclusions on the individual aspects they investigate. These approaches usually focus on a fraction of the problem, examining it very deeply and theoretically. Their drawback is loss of comprehensiveness and ability to draw conclusions on an overall level and consequently being applicable to the existing conditions. Research on an inclusive level is sparse. In this particular research project, an inclusive appraisal approach was adopted, leading to the identification of three main variables: resources, human-user-satisfaction, and technical. Consequently, this led to a combination of purely quantitative and qualitative data. Case studies were conducted on existing buildings in order to assess the actual performance of the various alternative structural systems. This paper presents the procedure followed for the identification of the research variables and the focus on the development of the model of quantification. The latter is of vital importance if the problem of incompatibility of data is to be solved, overall relation of findings is to be achieved and holistic conclusions are to be drawn.

doi https://doi.org/10.52842/conf.ecaade.1993.x.q8a
summary This paper shows work exemplifying the further extent of computer capabilities in the field of design. The work stems from a belief that for computers to be used effectively within the architectural profession their utility must stretch far beyond the process of description of geometric data, but be incorporated in the fundamental roots of design: that of conceptual design. Computers can be used to access the knowledge we have and then formulate this knowledge into a working language of design. Computers can be used to generate space and form in accordance with any relationship the designer may choose to set. This allows them to be used from the very conception of design. It is only by working from the very beginning, the very basis of the design of a building that we can fully develop the integration of computers in the construction industry. The work undertaken sets out primarily to explore one of the ways computers could be used in the field of architectural design. In recognition that an important byproduct of any design search is the enhanced understanding of the problem itself, the work was directed towards a particular project. This allowed each stage of thought to be to be considered as it arose and subsequently incorporated into the design model. The work does not attempt to automise the design process but simply tries to explore some of the opportunities offered by computers and see if they can be easily incorporated into the design process offering design solutions that may not otherwise have been considered. The exploration resulted in a simple design process model that incorporates the more accessible and useful aspects of computer technology.

summary Within the Dutch Ministry of Transport a special Division on Transport and Traffic Research is occupied with all aspects concerning mobility and traffic safety on a national level. Research and advice on the quality of the road–infrastructure is one of the main topics. For road–design a set of very detailed guidelines have been developed. Construction and reconstruction of parts of the high–way–network are tested against these guidelines. In this matter the actual road–user takes a central place. In the design–phase of a project on road-infrastructure contributions of a number of experts are taken into account. Expert–opinions on elements of the road–design result in a overall road–design. The road–scene of the overall–design is tested against visual requirements for safe driving, from a drivers point of view. Goal is to give advice on improvement of the visual quality of the road design. Research in this field is now carried out by Grontmij Consulting Engineers, mainly under authority of the Ministry of Transport. Key–word is Improvement of Quality. Who is going to notice? Who will benefit from it? Of course it is a comforting thought for road–owners and designers to know they won’t have to be ashamed for what they have come up with. Primary goal is that ‘We the people’ are provided with a high–standard road infrastructure. The road–scene research section studies the quality of the visual information as presented to the roadusers. We try to create visual circumstances in which drivers will be able to perform their driving task is a proper way. When the visual representation in the brain differs from reality, you have a serious problem. A traffic safety problem, with casualties and fatalities. A burden for society, financially and emotionally.

summary Presently, only a small percentage of people in the world typically hire an architect to design and build a home which is tailored to their preference. Besides the architect’s fee, clients also need to wait an interminable time for design and construction. Factory-made prefabricated housing systems tried to solve this problem previously. However, most pioneers failed to address the issues of variability and individual needs (Kieran & Timberlake, 2004). Plants closed because they produced more than the market demand, and prefabricated housing provided less flexibility than the traditional stick-built housing. The advanced digital technology makes it possible to communicate design ideas and concepts to others more effectively. The project delivery process leads itself to customization, embodying principles of lean production (Pine, 1993), flexible computer-integrated design interaction with clients, and reduced cycle times; all effecting rapid response between consumers and producers.

title The Vector-drawing as a Means to Unravel Architectural Communication in the Past

doi https://doi.org/10.52842/conf.ecaade.1993.x.q9a
summary Unlike in painting, in architecture one single person never controls the whole process between conception and realization of a building. Ideas of what the building will eventually look like, have to be conveyed from patron to the actual builders, by way of drawings. Generally the architect is the key-figure in this process of communication of visual ideas. Nowadays many architects design their new buildings by using computers and Computer-Aided (Architectural) Design programs like AutoCad and VersaCAD. Just like traditional drawings, all these computer drawings are in fact vector-drawings; a collection of geometrical primitives like lines, circle segments etc. identified by the coordinates of their end points. Vector-based computer programs can not only be used to design the future, but also as a means to unravel the architectural communication in the past. However, using the computer as an analyzing tool for a better comprehension of the past is not as simple as it seems. Historical data from the past are governed by unique features of date and place. The complexity of the past combined with the straightforwardness of the computer requires a pragmatic and basic approach in which the computer acts as a catalytic agent, enabling the scholar to arrive manually at his own - computer-assisted - conclusions. From this it turns out that only a limited number of projects of a morphological kind are suited to contribute to new knowledge, acquired by the close-reading of the information gained by way of meaningful abstraction. An important problem in this respect is how to obtain the right kind of architectural information. All four major elements of the building process - architect, design, drawing and realization - have their own different and gradually shifting interpretations in the past. This goes especially for the run-of-the-mill architecture which makes up the larger part of the historical urban environment. Starting with the architect, one has to realize that only a very limited part of mainstream architecture was designed by architects. In almost all other cases the role of the patron and the actual builder exceeds that of the architect, even to the extent that they designed buildings themselves. The position of design and drawing as means of communication also changed in the past. Until the middle of the nineteenth century drawings were not the chief means of communication between architects and builders, who got the gist of the design from a model, or, encountering problems, simply asked the architect or supervisor. From the nineteenth century onwards the use of drawings became more common, but almost never represented the building entirely "as built". In 1991 I published my Ph.D. thesis: Constructing the past: computerassisted architectural-historical research: the application of image-processing using the computer and Computer-Aided Design for the study of the urban environment, illustrated by the use of treatises in seventeenth-century architecture (Utrecht 1991). Here, a reconstruction of this historical communication process will be presented on the basis of a project studying the use of the Classical orders as prescribed in various architectural treatises, compared to the use of the orders in a specific group of still existing buildings in The Netherlands dating from the late sixteenth and entire seventeenth century. Comparisons were made by using vector-drawings. Both the illustrations in the the treatises and actual buildings were "translated" into computer-drawings and then analyzed.

summary "Space," which has long been an important concept in architecture (Bloomer & Moore, 1977; Mitchell, 1995, 1999), has attracted interest of researchers from various academic disciplines in recent years (Agnew, 1993; Benko & Strohmayer, 1996; Chang, 1999; Foucault, 1982; Gould, 1998). Researchers from disciplines such as anthropology, geography, sociology, philosophy, and linguistics regard it as the basis of the discussion of various theories in social sciences and humanities (Chen, 1999). On the other hand, since the invention of Internet, Internet users have been experiencing a new and magic "world." According to the definitions in traditional architecture theories, "space" is generated whenever people define a finite void by some physical elements (Zevi, 1985). However, although Internet is a virtual, immense, invisible and intangible world, navigating in it, we can still sense the very presence of ourselves and others in a wonderland. This sense could be testified by our naming of Internet as Cyberspace -- an exotic kind of space. Therefore, as people nowadays rely more and more on the Internet in their daily life, and as more and more architectural scholars and designers begin to invest their efforts in the design of virtual places online (e.g., Maher, 1999; Li & Maher, 2000), we cannot help but ask whether there are indeed sensible spaces in Internet. And if yes, these spaces exist in terms of what forms and created by what ways?To join the current interdisciplinary discussion on the issue of space, and to obtain new definition as well as insightful understanding of "space", this study explores the spatial phenomena in Internet. We hope that our findings would ultimately be also useful for contemporary architectural designers and scholars in their designs in the real world.As a preliminary exploration, the main objective of this study is to discover the elements involved in the creation/construction of Internet spaces and to examine the relationship between human participants and Internet spaces. In addition, this study also attempts to investigate whether participants from different academic disciplines define or experience Internet spaces in different ways, and to find what spatial elements of Internet they emphasize the most.In order to achieve a more comprehensive understanding of the spatial phenomena in Internet and to overcome the subjectivity of the members of the research team, the research design of this study was divided into two stages. At the first stage, we conducted literature review to study existing theories of space (which are based on observations and investigations of the physical world). At the second stage of this study, we recruited 8 Internet regular users to approach this topic from different point of views, and to see whether people with different academic training would define and experience Internet spaces differently.The results of this study reveal that the relationship between human participants and Internet spaces is different from that between human participants and physical spaces. In the physical world, physical elements of space must be established first; it then begins to be regarded as a place after interaction between/among human participants or interaction between human participants and the physical environment. In contrast, in Internet, a sense of place is first created through human interactions (or activities), Internet participants then begin to sense the existence of a space. Therefore, it seems that, among the many spatial elements of Internet we found, "interaction/reciprocity" Ñ either between/among human participants or between human participants and the computer interface Ð seems to be the most crucial element.In addition, another interesting result of this study is that verbal (linguistic) elements could provoke a sense of space in a degree higher than 2D visual representation and no less than 3D visual simulations. Nevertheless, verbal and 3D visual elements seem to work in different ways in terms of cognitive behaviors: Verbal elements provoke visual imagery and other sensory perceptions by "imagining" and then excite personal experiences of space; visual elements, on the other hand, provoke and excite visual experiences of space directly by "mapping".Finally, it was found that participants with different academic training did experience and define space differently. For example, when experiencing and analyzing Internet spaces, architecture designers, the creators of the physical world, emphasize the design of circulation and orientation, while participants with linguistics training focus more on subtle language usage. Visual designers tend to analyze the graphical elements of virtual spaces based on traditional painting theories; industrial designers, on the other hand, tend to treat these spaces as industrial products, emphasizing concept of user-center and the control of the computer interface.The findings of this study seem to add new information to our understanding of virtual space. It would be interesting for future studies to investigate how this information influences architectural designers in their real-world practices in this digital age. In addition, to obtain a fuller picture of Internet space, further research is needed to study the same issue by examining more Internet participants who have no formal linguistics and graphical training.

title Architectural Theory and Design Grammars

summary The idea of artificial brains and artificial intelligence (AI) has been subject to criticism. The objection of J. Searle, for instance, which has been published in 1984 and which was partially directly addressed to one of the centres of AI, the Carnegie Mellon University in Pittsburgh, is mainly based on two points: (1) interactions between physiological and mental functions, and (2) the intentionality and context-relatedness of meaning. - With an emphasis on architectural design, this paper is about the second point, because the problem of meaning is a neuralgic point in the discussion of "artificial intelligence in design" (AID). Technical parameters are incompatible with mechanisms of meaning in any field of artistic, cultural or non-technical expression. This point, that is the relation between acts of meaning and acts of technical problem-solving and, connectedly, the relation between technological and architectural design, has been widely ignored in the discussion on AID. The development seems to be dominated by the tacit assumption that architecture can be articulated and generated purely in technical and formal terms of information processing beyond the field of architecture itself. Design and shape grammars have become a well established field in the discussion of AID, also with respect to architecture. But questions of architectural history and theory are touched on only incidentally and not sufficiently in this discussion. The problem is not, in other words, simply to include more or less unrelated cases of architecture, or architectural concepts -even if these are famous ones, such as Laugier's original hut for instance but to establish structural relations between arguments of architectural theory and arguments of AID.

title Case-Based Structural Design - using weakly structured product and process information
source Chalmers University of Technology, Division of Steel and Timber Structures, Publ. S 00:7, Göteborg
summary Empirical knowledge plays a significant role in the human reasoning process. Previous experiences help in understanding new situations and in finding solutions to new problems. Experience is used when performing different tasks, both those of routine character and those that require specific skill. This is also the case for structural designers. Over 50% of the work done by the designer on a day-to-day basis is routine design that consists of modifying past designs (Moore 1993). That is, most of the design problems that the designer solves have been solved before, in many cases over and over again. In recent years, researchers have started to study if cases (information about specific problem-solving experiences) could be used as a representation of experiential knowledge. Making use of past experience in the form of cases is commonly known as Case-Based Reasoning (CBR). A requirement for Case-Based Design (Case-Based Reasoning applied in design) to be successful is that the design information is computerized. One information type used in structural design that is starting to become computerized is the one in design calculation documents. Such information is weakly structured (which holds for much of the information representing experience) and it contains both product and process information. In this thesis it is shown how the weak structure of this information can be used to subdivide it into components, which in turn makes it possible to apply the object-oriented abstraction principles also to this kind of information. It is also shown how the detailed design process can be represented and how this representation can facilitate automatic acquisition, retrieval of relevant old design information, and adaptation of this information. Two prototypes BridgeBase and ARCADE have been developed, where the principles described above are applied. Using ARCADE, the more general of these two prototypes, it is presented how information in computerized design calculation documents, gathered from real projects, can serve as containers and carriers for both project information and experience. The experience from the two prototypes shows that Case-Based Design can be usable as a tool for structural engineers.

title Case-Based Reasoning
source San Mateo, CA:Morgan Kaufmann
summary Case-based reasoning systems store information about situations in their memory. As new problems arise, similar situations are searched to help solve them. The author places special emphasis on applying case-based reasoning to complex real-world problem- solving tasks such as medical diagnosis, design, conflict resolution, and planning. The approach combines cognitive science and engineering, and is based on analysis of both expert and common- sense tasks. Guidelines for building case-based expert systems are provided.

title Recognizing Emergent Subshapes in Design Problem Solving: A Connectionist Investigation
source Education and Practice: The Critical Interface [ACADIA Conference Proceedings / ISBN 1-880250-02-0] Texas (Texas / USA) 1993, pp. 131-139
doi https://doi.org/10.52842/conf.acadia.1993.131
summary Human problem-solving behavior has been modelled as a search through the space as defined as problem states, within which earlier states move to subsequent ones by applying rules in the human mind until the goal state is found. This cognitive model of problem-solving has been broadly accepted and has become dominant in both cognitive psychology and artificial intelligence (AI). In the field of computeraided architectural design (CAAD), search models are also widely used for solving design problems, although various foci of design knowledge are differently represented by shape grammars, graphs, and knowledge-based systems using predicate logic for different purports.

In design search, design evolves from one state to another by exhaustively or heuristically applying proper rules. Each rule application involves, first, pattern-matching the antecedent of a rule to the current state and, second, transforming the matched portion of that state into the consequence of the rule. However pattern-matching techniques of current CAAD systems are still limited. In current CAAD systems, only those two squares can be dealt with by patternmatching for further development. However, a human designer can effortlessly recognize not only those two but other emergent subshapes, for example a smaller square in the middle where the two squares overlap and two L-shapes in the corners. Therefore a human designer can thoroughly deliberate all these alternatives before making a decision. In other words, human designer is capable of restructuring shapes in terms of emergent subshapes in any step of designing.

title Computer Assistance in Design Engineering User Interface Evaluation Methods
source Behaviour and Information Technology 1993 v.12 n.3 p.165-173
summary The design engineering process is analysed from a cognitive ergonomics point of view, relating it to models of problem-solving and cognitive skills. Observations from several Swedish studies are discussed in this framework. Results indicate that CAD systems require some re-thinking; in particular concepts related to the computer storage have to be incorporated in the problem space of design. As to heuristics, CAD systems seem to offer a wide variety of working. Cognitive skills related to CAD seem to be easily acquired, although the transition between different CAD systems will cause some initial problems. In general it is found that current CAD systems mainly support the detail design phase. Some ideas for future systems which would support the conceptual design phase in addition are discussed.
