title	How do Architects Design?
source	Artificial Intelligence and Pattern Recognition in Computer Aided Design. North-Holland Publishing Company, 1978. pp. 65-98. includes bibliography
summary	This study is proposes a descriptive model of the design behavior of architects. In the first section a framework for the model is proposed. In the second section the framework is tested against empirical data. 11 information processing mechanisms are observed in the data. Eight of these: information acquisition, problem interpretation, problem representation, solution generation, solution integration, solution evaluation, perception and sketching, are used in developing design solutions. The three remaining mechanisms: design 'plans,' transformation rules and design-symbols, represent the categories of the priori knowledge used in design. In the third section these three knowledge mechanisms are explored in detail using the results of two additional experiments with designers

title	Syntactic structures
source	The Hague : Mouton
summary	Noam Chomsky's first book on syntactic structures is one of the first serious attempts on the part of a linguist to construct within the tradition of scientific theory-construction a comprehensive theory of language which may be understood in the same sense that a chemical, biological theory is understood by experts in those fields. It is not a mere reorganization of the data into a new kind of library catalogue, nor another specualtive philosophy about the nature of man and language, but rather a rigorus explication of our intuitions about our language in terms of an overt axiom system, the theorems derivable from it, explicit results which may be compared with new data and other intuitions, all based plainly on an overt theory of the internal structure of languages; and it may well provide an opportunity for the application of explicity measures of simplicity to decide preference of one form over another form of grammar.

title	The Development of Three-Dimensional Spatial Modeling Techniques for the Construction of Nuclear Power Plants
source	SIGGRAPH-ACM Quarterly Report. August, 1978. pp. 26-30 : ill. includes bibliography
summary	This paper presents the results of the first phase of a research project on the application of spatial modeling techniques to the process of planning and executing the construction of a nuclear power plant. A computer modeling technique, based on sets of polyhedra and spatial set operations, was developed and applied to modeling the components of a nuclear power plant. The objectives of the modeling are: To store and retrieve information about the various systems in the facility; to produce drawings of those systems from any angle in differing amounts of detail; to aid in the search for interference among the parts of the plant by identifying those elements that occupy the same space or are too close to each other; to calculate information such as surface area, length, and volume of selected elements of the plant; and to aid in finding the optimum construction sequence by simulating the construction of selected areas of the plant. Computer techniques are described for inputing information by digitizing directly from engineering drawings, for editing the spatial model, for management of the spatial and non-spatial data, and for graphic output from the model. The software is implemented on the University central time- sharing computer system and on a mini-computer system in the Architectural Research Laboratory

doi	https://doi.org/10.52842/conf.acadia.2009.026
source	ACADIA 09: reForm( ) - Building a Better Tomorrow [Proceedings of the 29th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-9842705-0-7] Chicago (Illinois) 22-25 October, 2009), pp. 26-29
summary	The architectural office of Herzog & de Meuron (HdM) started in 1978 and has grown to a company of about 330 employees. Besides the two founding partners who participate in every project there are nine additional partners who take responsibility for individual projects. Furthermore, the office collaborates with artists and outside experts of various fields to support and enhance the available knowledge and skills. The partners ensure that each project has a distinct and unique identity and is well adapted to its environment. This emphasis on the uniqueness of a project characterizes the design philosophy of HdM.The growth of the office and the size and complexity of the projects has demanded continuous adaptation of the office structure. The amount of required data is increasing exponentially, while the design cycles are, generally, becoming shorter. The challenge is to find the right tools and media. HdM does not restrict itself to the realm of digital tools but, rather, uses all possible media: hand sketches in pencil, together with diagrams, drawings, and images, as well as physical and digital models.

title	Digital Architecture in CAD studio and Internet-based competition
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	Architectural design has been changing because of the vast and creative use of computer in different ways. From the viewpoint of designing itself, computer has been used as drawing tools in the latter phase of design (Mitchell 1977; Coyne et al. 1990), presentation and simulation tools in the middle phase (Liu and Bai 2000), and even critical media which triggers creative thinking in the very early phase (Maher et al. 2000; Liu 1999; Won 1999). All the various roles that computer can play have been adopted in a number of professional design corporations and so-called computer-aided design (CAD) studio in schools worldwide (Kvan 1997, 2000; Cheng 1998). The processes and outcomes of design have been continuously developing to capture the movement of the computer age. However, from the viewpoint of social-cultural theories of architecture, the evolvement of design cannot be achieved solely by designers or design processes. Any new idea of design can be accepted socially, culturally and historically only under one condition: The design outcomes could be reviewed and appreciated by critics in the field at the time of its production (Csikszentmihalyi 1986, 1988; Schon and Wiggins 1992; Liu 2000). In other words, aspects of design production (by designers in different design processes) are as critical as those of design appreciation (by critics in different review processes) in the observation of the future trends of architecture.Nevertheless, in the field of architectural design with computer and Internet, that is, so-called computer-aided design computer-mediated design, or internet-based design, most existing studies pay more attentions to producing design in design processes as mentioned above. Relatively few studies focus on how critics act and how they interact with designers in the review processes. Therefore, this study intends to investigate some evolving phenomena of the interaction between design production and appreciation in the environment of computer and Internet.This paper takes a CAD studio and an Internet-based competition as examples. The CAD studio includes 7 master's students and 2 critics, all from the same countries. The Internet-based competition, held in year 2000, includes 206 designers from 43 counties and 26 critics from 11 countries. 3 students and the 2 critics in the CAD studio are the competition participating designers and critics respectively. The methodological steps are as follows: 1. A qualitative analysis: observation and interview of the 3 participants and 2 reviewers who join both the CAD studio and the competition. The 4 analytical criteria are the kinds of presenting media, the kinds of supportive media (such as verbal and gesture/facial data), stages of the review processes, and interaction between the designer and critics. The behavioral data are acquired by recording the design presentation and dialogue within 3 months. 2. A quantitative analysis: statistical analysis of the detailed reviewing data in the CAD studio and the competition. The four 4 analytical factors are the reviewing time, the number of reviewing of the same project, the comparison between different projects, and grades/comments. 3. Both the qualitative and quantitative data are cross analyzed and discussed, based on the theories of design thinking, design production/appreciation, and the appreciative system (Goodman 1978, 1984).The result of this study indicates that the interaction between design production and appreciation during the review processes could differ significantly. The review processes could be either linear or cyclic due to the influences from the kinds of media, the environmental discrepancies between studio and Internet, as well as cognitive thinking/memory capacity. The design production and appreciation seem to be more linear in CAD studio whereas more cyclic in the Internet environment. This distinction coincides with the complementary observations of designing as a linear process (Jones 1970; Simon 1981) or a cyclic movement (Schon and Wiggins 1992). Some phenomena during the two processes are also illustrated in detail in this paper.This study is merely a starting point of the research in design production and appreciation in the computer and network age. The future direction of investigation is to establish a theoretical model for the interaction between design production and appreciation based on current findings. The model is expected to conduct using revised protocol analysis and interviews. The other future research is to explore how design computing creativity emerge from the process of producing and appreciating.

title	An Incompatibility Projector Based on an Interpolant of Gregory
source	computer Graphics and Image Processing. 1978. vol. 8: pp. 294-298. includes bibliography
summary	This paper develops an 'incompatibility Projector' Qm, which is an intrinsically bivariate projector that is not the composition of two univariate projectors. Then it employs Qm to manifest a recent rational interpolant due to Gregory in projector form as a triple Boolean sum. This creates a mold for additional compatibility projectors which yield interpolants to functions that do not meet the ordinary compatibility constraints required for Boolean sum interpolation

title	Analysis of dimensions and tolerances in computer-aided mechanical design
source	Computer Aided Design, vol.10, n.3, may 1978, pp. 161-166
summary	The paper sets forth a theory to explain how dimensions and views combine to specify the shape of a mechanical component. It provides a method to determine whether a component is under, over, or exactly defined by a given dimensioning scheme. Measures for assessing the quality of a scheme are proposed. A solution is offered to a problem of tolerancing: given a toleranced dimensioning scheme, find the resulting tolerances between undimensioned parts of a component.

title	A Cognitive Framework of Collaborative Design Between Architects and Manufacturer-Designers
doi	https://doi.org/10.52842/conf.caadria.2003.855
source	CAADRIA 2003 [Proceedings of the 8th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 974-9584-13-9] Bangkok Thailand 18-20 October 2003, pp. 855-870
summary	The widespread application of prefabricated products in building has made prefabrication an indispensable part of building processes. In this context, instead of handling every detail by architects themselves, some parts of architectural design have been transferred to manufacturer-designers. This inevitably brings about problems in the integration of prefabricated products and the specific buildings they serve. As a result, collaboration between architects and manufacturer-designers takes place in building processes in various forms and extents (non-, semi-, and full-collaboration). In this study, we aim to investigate collaborative design process from the cognitive aspect of design generation between architects and manufacturer-designers in terms of project-related products design. By applying the Kernel of Conceptual System theory (Tzonis et al., 1978), we intend to set up two empirical models in terms of design differences' formation in collaborative design process based on a case study with seeking the answers for the following research questions: 1. What kinds of design differences are raised in design processes? 2. Why the design differences are raised in design processes? 3. What implications could be made in developing computational models to facilitate collaborative design between architects and manufacturer-designers?

title	Practices of Distributed Intelligence and Designs for Education
source	Distributed Cognitions, edited by G. Salomon. New York, NY: CambridgeUniversity Press
summary	v Knowledge is commonly socially constructed, through collaborative efforts... v Intelligence may also be distributed for use in designed artifacts as diverse as physical tools, representations such as diagrams, and computer-user interfaces to complex tasks. v Leont'ev 1978 for activity theory that argues forcibly for the centrality of people-in-action, activity systems, as units of analysis for deepening our understanding of thinking. v Intelligence is distributed: the resources that shape and enable activity are distributed across people, environments, and situations. v Intelligence is accomplished rather than possessed. v Affordance refers to the perceived and actual properties of a thing, primarily those functional properties that determine how the thing could possibly be used. v Norman 1988 on design and psychology - the psychology of everyday things" v We deploy effort-saving strategies in recognition of their cognitive economy and diminished opportunity for error. v The affordances of artifacts may be more or less difficult to convey to novice users of these artifacts in the activities to which they contribute distributed intelligence. v Starts with Norman's seven stages of action Ø Forming a goal; an intention § Task desire - clear goal and intention - an action and a means § Mapping desire - unable to map goal back to action § Circumstantial desire - no specific goal or intention - opportunistic approach to potential new goal § Habitual desire - familiar course of action - rapidly cycle all seven stages of action v Differentiates inscriptional systems from representational or symbol systems because inscriptional systems are completely external, while representational or symbol systems have been used in cognitive science as mental constructs. v The situated properties of everyday cognition are highly inventive in exploiting features of the physical and social situation as resources for performing a task, thereby avoiding the need for mental symbol manipulations unless they are required by that task. v Explicit recognition of the intelligence represented and representable in design, specifically in designed artifacts that play important roles in human activities. v Once intelligence is designed into the affordances properties of artifacts, it both guides and constrains the likely contributions of that artifact to distributed intelligence in activity. v Culturally valued designs for distributed intelligence will change over time, especially as new technology becomes associated with a task domain. v If we treat distributed intelligence in action as the scientific unit of analysis for research and theory on learning and reasoning... Ø What is distributed? Ø What constraints govern the dynamics of such distributions in different time scales? Ø Through what reconfigurations of distributed intelligence might the performance of an activity system improve over time? v Intelligence is manifest in activity and distributed in nature. v Intelligent activities ...in the real world... are often collaborative, depend on resources beyond an individual's long-term memory, and require the use of information-handling tools... v Wartofsky 1979 - the artifact is to cultural evolution what the gene is to biological evolution - the vehicle of information across generations. v Systems of activity - involving persons, environment, tools - become the locus of developmental investigation. v Disagrees with Salomon et al.'s entity-oriented approach - a language of containers holding things. v Human cognition aspires to efficiency in distributing intelligence - across individuals, environment, external symbolic representations, tools, and artifacts - as a means of coping with the complexity of activities we often cal "mental."
