title	Any Progress in Systematic Design?

summary	In order to discuss this question it is necessary to reflect awhile on design methods in general. The usual categorization discusses 'generations' of design methods, but Levy (1981) proposes an alternative approach. He identifies five paradigm shifts during the course of the twentieth century which have influenced design methods debate. The first paradigm shift was achieved by 1920, when concern with industrial arts could be seen to have replaced concern with craftsmanship. The second shift, occurring in the early 1930s, resulted in the conception of a design profession. The third happened in the 1950s, when the design methods debate emerged; the fourth took place around 1970 and saw the establishment of 'design research'. Now, in the 1980s, we are going through the fifth paradigm shift, associated with the adoption of a holistic approach to design theory and with the emergence of the concept of design ideology. A major point in Levy's paper was the observation that most of these paradigm shifts were associated with radical social reforms or political upheavals. For instance, we may associate concern about public participation with the 1970s shift and the possible use (or misuse) of knowledge, information and power with the 1980s shift. What has emerged, however, from the work of colleagues engaged since the 1970s in attempting to underpin the practice of design with a coherent body of design theory is increasing evidence of the fundamental nature of a person's engagement with the design activity. This includes evidence of the existence of two distinctive modes of thought, one of which can be described as cognitive modelling and the other which can be described as rational thinking. Cognitive modelling is imagining, seeing in the mind's eye. Rational thinking is linguistic thinking, engaging in a form of internal debate. Cognitive modelling is externalized through action, and through the construction of external representations, especially drawings. Rational thinking is externalized through verbal language and, more formally, through mathematical and scientific notations. Cognitive modelling is analogic, presentational, holistic, integrative and based upon pattern recognition and pattern manipulation. Rational thinking is digital, sequential, analytical, explicatory and based upon categorization and logical inference. There is some relationship between the evidence for two distinctive modes of thought and the evidence of specialization in cerebral hemispheres (Cross, 1984). Design methods have tended to focus upon the rational aspects of design and have, therefore, neglected the cognitive aspects. By recognizing that there are peculiar 'designerly' ways of thinking combining both types of thought process used to perceive, construct and comprehend design representations mentally and then transform them into an external manifestation current work in design theory is promising at last to have some relevance to design practice.

title	A digital Procedure of Building Construction: A practical project
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	In earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.

title	Virtual Reality and the Future of Publishing Archaeological Excavations: the multimedia publication of the prehistoric settlement on Tsoungiza at Ancient Nemea
source	New York: The Metropolitan Museum of Art
summary	The Nemea Valley Archaeological Project is a study of settlement and land use in a regional valley system in Greece extending from the Upper Paleolithic until the present. Active field research was conducted by four teams between 1981 and 1990. The first component was a regional archaeological survey. Second, and closely related to the first, was a social anthropological study of modern settlement and land use. Next was a team assigned to excavate the succession of prehistoric settlements of Ancient Nemea on Tsoungiza. Last, historical ecologists, a palynologist, and a geologist formed the environmental component of the research. As a result of advances in electronic publishing, plans for the final publication of the Nemea Valley Archaeological Project have evolved. Complete publication of the excavation of the prehistoric settlements of Ancient Nemea on Tsoungiza will appear in an interactive multimedia format on CD/DVD in Fall 2000. This project is planned to be the first electronic publication of the American School of Classical Studies at Athens. We have chosen to publish in electronic format because it will meet the needs and interests of a wider audience, including avocational archaeologists, advanced high school and college students, graduate students, and professional archaeologists. The multimedia format on CD/DVD will permit the inclusion of text, databases, color and black-and-white images, two and three-dimensional graphics, and videos. This publication is being developed in cooperation with Learning Sites, Inc., which specializes in interactive three-dimensional reconstructions of ancient worlds http://www.learningsites.com. The Nemea Valley Archaeological Project is particularly well prepared for the shift towards electronic publishing because the project's field records were designed for and entered in computer databases from the inception of the project. Attention to recording precise locational information for all excavated objects enables us to place reconstructions of objects in their reconstructed architectural settings. Three-dimensional images of architectural remains and associated features will appear both as excavated and as reconstructed. Viewers will be able to navigate these images through the use of virtual reality. Viewers will also be able to reference all original drawings, photographs, and descriptions of the reconstructed architecture and objects. In this way a large audience will be able to view architectural remains, artifacts, and information that are otherwise inaccessible.

title	The K-D-B-Tree : A Search Structure of Large Multidimensional Dynamic Indexes
source	22 p. : ill
summary	Pittsburgh, PA: Department of Computer Science, CMU, February, 1981. CMU-CS-81-106. includes some bibliographical references. The problem of retrieving multikey records via range queries form a large, dynamic index is considered. By large it is meant that most of the index must be sorted on secondary memory. By dynamic it is meant that insertions and deletions are intermixed with queries, so that the index cannot be built beforehand. A new data structure, the K-D-B-tree, is presented as a solution to this problem. K-D-B-trees combine properties of K-D-trees and B-trees. It is expected that the multidimensional search efficiency of balanced K-D-trees and the I/O efficiency of B-trees should both be approximated in the K-D-B-tree. Preliminary experimental results that tend to support this are reported

title	The Complexity of Manipulating Hierarchically Defined Sets of Rectangles
source	40 p. : ill. Pittsburgh, PA: Department of Computer Science, CMU., April, 1981. CMU-CS-81-109. includes bibliography
summary	Algorithms that manipulate sets of rectangles are of great practical importance in VLSI design systems and other applications. Although much theoretical work has appeared recently on the complexity of rectangle problems, it has assumed that the inputs are given as a list of rectangles. In this paper the authors study the complexity of rectangle problems when the inputs are given in a hierarchical language that allows the designer to build large designs by replicating small designs. They show that while most of the problems are NP-hard in the general case, there are O(N log N) algorithms that process inputs obeying certain restrictions

source	ACM IEEE Design Automation Conference Proceedings (18th : 1981 : Nashville, Tennessee). pp. 75-81 : ill. includes bibliography
summary	A general purpose, research oriented, interactive modeling system is presented. It is based on two different coherent polyhedral shape representations: a planar graph, used for computation and data manipulation, and relational-database for compact store and general communication with application programs. The two representations effectively partition the system shape-space into active and inactive shapes, respectively. These are explicitly interchangeable by the user, keeping the actual workspace at a manageable size. The basic functionalities provided by the system include the combination of primitive shapes into complex objects by means of spatial set operators (union, intersection and difference), their modeling by means of scaling, rotation and translation, spatial interference detection and graphical display capabilities

title	Systems Thinking, Systems Practice
source	John Wiley & Sons, Chichester
summary	Whether by design, accident or merely synchronicity, Checkland appears to have developed a habit of writing seminal publications near the start of each decade which establish the basis and framework for systems methodology research for that decade."" Hamish Rennie, Journal of the Operational Research Society, 1992 Thirty years ago Peter Checkland set out to test whether the Systems Engineering (SE) approach, highly successful in technical problems, could be used by managers coping with the unfolding complexities of organizational life. The straightforward transfer of SE to the broader situations of management was not possible, but by insisting on a combination of systems thinking strongly linked to real-world practice Checkland and his collaborators developed an alternative approach - Soft Systems Methodology (SSM) - which enables managers of all kinds and at any level to deal with the subtleties and confusions of the situations they face. This work established the now accepted distinction between hard systems thinking, in which parts of the world are taken to be systems which can be engineered, and soft systems thinking in which the focus is on making sure the process of inquiry into real-world complexity is itself a system for learning. Systems Thinking, Systems Practice (1981) and Soft Systems Methodology in Action (1990) together with an earlier paper Towards a Systems-based Methodology for Real-World Problem Solving (1972) have long been recognized as classics in the field. Now Peter Checkland has looked back over the three decades of SSM development, brought the account of it up to date, and reflected on the whole evolutionary process which has produced a mature SSM. SSM: A 30-Year Retrospective, here included with Systems Thinking, Systems Practice closes a chapter on what is undoubtedly the most significant single research programme on the use of systems ideas in problem solving. Now retired from full-time university work, Peter Checkland continues his research as a Leverhulme Emeritus Fellow. "

title	Man Machine Interface Problems in Computer Aided Architectural Design
source	1981. pp. 231-250 : ill. includes bibliography. -- discussion (pp. 247-250)
summary	The author and two other researchers conducted a world-wide survey of existing computer aided architectural design programs in 1978. The purpose of the survey was to validate an earlier study of the architectural design process and to investigate problem areas in Computer Aided Architectural Design (CAAD). The survey indicated that two problems of man machine interaction in CAAD, though partly solved, remain a challenge for computer scientists: the description and graphical representation of three-dimensional objects. The formalization of the information collected in the survey, together with the experience of the author in teaching computer graphics to architecture students for the past ten years, is used to give some insight in these two problems and to make some recommendations for the improvement of the man machine interface in CAAD

title	Computers in Architecture, Design, and Fine and Performing Arts Education
source	5, [6] p. May, 1981
summary	In the next ten years it is expected that the processes and techniques for teaching design will greatly change. Feedback on design decisions - visually and analytically - will be fast and more powerful than is possible today. Much of the busy paper and pencil construction work will be eliminated or greatly reduced. The author anticipates students designing buildings and artifacts on the computer, quickly and with sophistication, achieving results beyond what can be expected through manually based education today. This proposal cannot realize this whole revolution. Rather, it attempts to only take a step outward from the neck of a funnel, showing people opportunities and providing a framework that allows easy extension. Some of these extensions, most of them trivial to develop, are presented in the scenario section of the proposal

title	Lego Free-Form? Towards a Modularized Free-Form Construction

summary	Design Media is the tool designers use for concept realization (Schon and Wiggins, 1992; Liu, 1996). Design thinking of designers is deeply effected by the media they tend to use (Zevi, 1981; Liu, 1996; Lim, 2003). Historically, architecture is influenced by the design media that were available within that era (Liu, 1996; Porter and Neale, 2000; Smith, 2004). From the 2D plans first used in ancient egypt, to the 3D physical models that came about during the Renaissance period, architecture reflects the media used for design. When breakthroughs in CAD/CAM technologies were brought to the world in the twentieth century, new possibilities opened up for architects.

doi	https://doi.org/10.52842/conf.acadia.2003.411
summary	In this research the concept of Solar Envelope has been used to develop a 3D Spatial Design Tool tool, SolCAD, for generating an envelope over a given site based on various design parameters. The solar envelope can be imagined as a container, whose boundaries are derived from the sun’s relative motion. Buildings within this container will not overshadow their surroundings during critical periods of solar access for passive and low-energy architecture. The solar envelope is a space-time construct. Its spatial limits are defined by the parameters of land parcel size, shape, orientation, topography and latitude. It also depends on the time or the period of the time for which it is designed. Its time limits are defined by the hours of each day and the season for which solar access is provided to the land parcel (Knowles 1981). This tool intends to generate an envelope over a site of any shape, size and orientation and for different boundary and height conditions of shadow lines. It is suitable for initial stages of building design process to determine the shape of the building even before the design has been conceptualized.

summary	The Association for Computer Aided Design in Architecture (ACADIA) was founded on October 17, 1981. The first meeting was held at Carnegie-Mellon University and attended by 24 founding members. When the history of ACADIA is discussed, out of these two dozen founders, three are frequently noted: William Mitchell, Charles Eastman, and Chris Yessios. Mitchell was a pioneer in computer-aided design and smart cities research and is, as Wassim Jabi, ACADIA’s 21st president put it, “one of ACADIA’s most famous founding members.”1 Eastman was not only ACADIA’s first president, but also one of the leading figures in the history of Building Information Modeling (BIM) and is often referred to as “the father of BIM.” Yessios is widely known for his work at Ohio State University and his role in developing Form.Z.

doi	https://doi.org/10.52842/conf.caadria.2006.x.q2e
summary	The paper demonstrates the need for advanced models of representation for circular dependency networks common in design problems that deal with multiple constraints. Constraints in a design problem are generally perceived as limitations to design exploration. The careful construction of constraint relationships can help to turn constraints into design drivers for the problem instead. Closely related to the notion that new goals may emerge from creating designs is the idea that one goal of planning may be the design activity itself (Simon 1981). The interplay of many constraints can lead to circular dependencies that make design exploration a challenge as any change causes ripples throughout the entire design construct. D’Arcy Thompson (1942) describes form as a diagram of forces. The construction of design representations that reflect such dependency networks pose a challenge and are far from exact matches of the task environment (Simon 1981). The paper proceeds in mapping these abstract observations of the circular dependencies in the design process to a chair experiment from design to fabrication giving detailed descriptions of the interdependencies of material, fabrication and aesthetic constraints. The experiment shows how those constraints were instrumental in achieving the aesthetics of the full scale prototype.

summary	A procedure for defining new languages of designs from known or given ones is presented. It is specified in terms of shape equivalence rules or shape equivalence rule schemata which allow shapes in spatial relations given or inferred from existing design languages to be replaced with other shapes. The new spatial relations so defined can be used to determine a wide variety of new, original languages of designs. The possibility of using shape equivalence rules or rule schemata for characterizing formal compositional aspects of historic styles or languages of designs and relationships between them is also discussed

title	The Language of the Prairie : Frank Lloyd Wright's Prairie Houses
source	Environment and Planning B. 1981. vol. 8: pp. 295-323 : ill. includes bibliography
summary	The following parametric shape grammar generates the compositional forms and specifies the function zones of Frank Lloyd Wright's prairie-style houses. The establishment of a fireplace is the key to the definition of the prairie-style house. Around this fireplace, functionally distinguished Froebelean-type blocks are recursively added and interpenetrated to from the basic compositions from which elaborated prairie-style houses are derived. The grammar is based on a corpus of eleven houses from the Winslow house, the evolutionary precursor of the style, to the Robie house, considered by many as the culmination of the style. Much has been written about prairie-style houses - their balance, their debt to Beaux Arts and Japanese design traditions, and their organic qualities. However, such descriptions do not explicitly inform us as to how prairie-style houses are constructed, and consequently provide little help in designing new members of this style. The power of a grammar, such as the one given here, is that it establishes a recursive structure from which new designs can be constructed. Three new prairie houses generated by the grammar as well as step-by-step generation of one of these designs are shown

summary	The concept of describing and analyzing architecture from a fractal point of view, on which this paper is based, can be traced back to Benoît Mandelbrot (1981) and Carl Bovill (1996) to a considerable extent. In particular, this includes the distinction between scalebound (offering a limited number of characteristic elements) and scaling objects (offering many characteristic elements of scale) made by B. Mandelbrot (1981). In the fi rst place such a differentiation is based upon a visual description. This paper explores the possibility of assistance by two measurement methods, fi rst time introduced to architecture by C. Bovill (1996). While the box-counting method measures or more precisely estimates the box-counting dimension D b of objects (e.g. facades), range analysis examines the rhythm of a design. As CAD programs are familiar to architects during design processes, the author implemented both methods in AutoCAD using the scripting language VBA. First measurements indicate promising results for indicating the distinction between what B. Mandelbrot called scalebound and scaling buildings.
