title	The Computerized Design Firm

summary	This paper is not just about the future of computerized design practice. It is about what to do today in contemplation of tomorrow-the issues of computercentered practice and the courses of action open to us can be discerned by the careful observer. The realities of computerized design practice are different from the issues on which design education still fixes its attention. To educators, the present paper recommends further clinical research on computerized design firms and suggests that case studies on the matter be developed and utilized as teaching material. Research conducted by the author of this paper indicates that a new form of design firm is emerging-the computerized design firm-totally supported and augmented by the new information technology. The present paper proceeds by introducing an abridged case study of an actual totally electronic, computerized design practice. Then, the paper concentrates on modelling the computerized design firm as an intelligent system, indicating non-trivial changes in its structure and strategy brought about by the introduction of the new information technology into its operations - among other considerations, different strategies and diverse conceptions of management and workgroup roles are highlighted. In particular, this paper points out that these structural and strategic changes reflect back on the technology of information with pressures to redirect present emphasis on the individual designer, working alone in an isolated workstation, to a more realistic conception of the designer as a member of an electronic workgroup. Finally, the paper underlines that this non-trivial conception demands that new hardware and software be developed to meet the needs of the electronic workgroup - which raises issues of human-machine interface. Further, it raises the key issues of how to represent and expose knowledge to users in intelligent information - sharing systems, designed to include not only good user interfaces for supporting problem-solving activities of individuals, but also good organizational interfaces for supporting the problem-solving activities of groups. The paper closes by charting promising directions for further research and with a few remarks about the computerized design firm's (near) future.

title	A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary	Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

title	Computer Modeling: A First Course in Design Computing

summary	Computation in design has long been a focus in our department. In recent years our faculty has paid particular attention to the use of computation in professional architectural education. The result is a shared vision of computers in the curriculum [Woodbury 1985] and a set of courses, some with considerable historyland others just now being initiated. We (Dave and Woodbury) have jointly developed and at various times over the last seven years have taught Computer Modeling, the most introductory of these courses. This is a required course for all the incoming freshmen students in the department. In this paper we describe Computer Modeling: its context, the issues and topics it addresses, the tasks it requires of students, and the questions and opportunities that it raises. Computer Modeling is a course about concepts, about ways of explicitly understanding design and its relation to computation. Procedural skills and algorithmic problem solving techniques are given only secondary emphasis. In essential terms, the course is about models, of design processes, of designed objects, of computation and of computational design. Its lessons are intended to communicate a structure of such models to students and through this structure to demonstrate a relationship between computation and design. It is hoped that this structure can be used as a framework, around which students can continue to develop an understanding of computers in design.

title	Integration of case-based reasoning and model-based reasoning for adaptive design problem solving
source	Ohio State University
summary	In the case-based approach to design, a novel problem is solved by adapting a design known to solve a related problem. Adapting a known design to solve a related problem by the commonly used methods of heuristic association and search, however, can be computationally expensive if the adaptation search space is not small. The adaptation space, then, needs to be decomposed into smaller and simpler spaces that can be searched more efficiently and effectively. The knowledge for decomposing the adaptation search space can be represented as a behavior-structure model that specifies how the structure of the known design results in its output behaviors. This research investigates the use of such behavior-structure models for adapting the designs of physical devices. Comprehension of how the output behaviors of a design arise from its structure is represented as a behavioral component-substance model for the design. The model explicitly specifies (i) the expected output behaviors of the design including its functions, (ii) the elementary structural and behavioral interactions between components and substances constituting the structure of the design, and (iii) the internal causal behaviors of the design that compose the elementary interactions into its output behaviors. The causal behaviors of the design, in this model, are indexed by the expected output behaviors for which they are responsible. The model aids case-based design in several ways. First, it identifies conceptual primitives for specifying the functions of designs, which are used to index the known designs stored in a case-based memory. Second, it identifies elementary types of behavior transformations and elementary types of structure modifications. Third, it provides knowledge for decomposition of the adaptation search space into smaller spaces so that the search for the needed structure modifications is localized. Fourth, it leads to a novel method for simulating the behavioral effects of structure modifications. The output and causal behaviors of the modified design, in this method, are derived by revising the output and causal behaviors of the known design. This integrative approach unifies case-based methods, associative methods, heuristic search methods, decomposition methods, and model-based methods into one architecture for adaptive design problem solving. Core portions of this approach have been implemented in an experimental design system called KRITIK.

title	Creative Processes : Can They be Automated?
source	Design Computing Unit, Department of Architectural and Design Science, University of Sydney, 1989. pp. 69-94. CADLINE has abstract only
summary	This paper attempts to identify the nature of creative processes and the relationship of those processes to the automated information processing techniques. Creative processes are characterized in terms of three categories of activity: problem solving, selection and reminding. Intuitive control is identified as a necessary component of any process capable of yielding a creative outcome. The nature of intuitive control is explored. The possibility of automating such control is considered. The implications of the presented characterization of creative processes in relation to the development of fully-automated systems and semi-automated support systems are described

title	Towards a New Generation of Computer Assistants for Architectural Design: An Existing Scenario
doi	https://doi.org/10.52842/conf.ecaade.1989.x.f9h

summary	The context in which designers operate is becoming more and more complex, owing to the large number of codes, new materials, technologies and professional figures; new instruments are needed, therefore, to support and verify design activity. The results obtained in the first years of 'computer era' were barely sufficient. The hardware and software available today is capable of producing a new generation of CAD systems which can aid the designer in the process of conceiving and defining building objects. At the CAD Laboratory in the Department of Building and Environmental Control Techniques at the 'La Sapienza' University of Rome, research is being carried out with the aim of defining a new kind of Knowledge-based assistant for architectural design. To this purpose a partnership has been established whit a private firm called CARTESIANA, whose partners are software houses, designing and building associations.

summary	The building industry involves a larger number of disciplines, operators and professionals than other industrial processes. Its peculiarity is that the products (building objects) have a number of parts (building elements) that does not differ much from the number of classes into which building objects can be conceptually subdivided. Another important characteristic is that the building industry produces unique products (de Vries and van Zutphen, 1992). This is not an isolated situation but indeed one that is spreading also in other industrial fields. For example, production niches have proved successful in the automotive and computer industries (Carrara, Fioravanti, & Novembri, 1989). Building design is a complex multi-disciplinary process, which demands a high degree of co-ordination and co-operation among separate teams, each having its own specific knowledge and its own set of specific design tools. Establishing an environment for design tool integration is a prerequisite for network-based distributed work. It was attempted to solve the problem of efficient, user-friendly, and fast information exchange among operators by treating it simply as an exchange of data. But the failure of IGES, CGM, PHIGS confirms that data have different meanings and importance in different contexts. The STandard for Exchange of Product data, ISO 10303 Part 106 BCCM, relating to AEC field (Wix, 1997), seems to be too complex to be applied to professional studios. Moreover its structure is too deep and the conceptual classifications based on it do not allow multi-inheritance (Ekholm, 1996). From now on we shall adopt the BCCM semantic that defines the actor as "a functional participant in building construction"; and we shall define designer as "every member of the class formed by designers" (architects, engineers, town-planners, construction managers, etc.).

summary	In these years the researches on the computer science applied to the building have had a considerable development. The applications concern the whole design process, from the programming to the design and from the execution control to the programmed maintenance with a great deal of problems solved using expert systems. It doesn't seem that the same care of men and means has been dedicated to the architectural design theory, to its deep roots which motivate it and to its peculiarity in comparison with other fields in which now the design, with the aid of the computer, is the only one possible. The designer of architectural objects has been always helped by design assistants: it is enough to think that the sixteenth century treatises are a group of rules, descriptions, solutions to design problems and that they represent the "knowledge" of the age. As the knowledge increased those treatises amplified to the encyclopaedic dimensions of the nineteenth-century handbooks and of those of the first years of this century, while new professional figures rose, the teaching developed and the building art became more and more complex.

title	A Study of Human Performance in Computer-Aided Architectural Design
source	International Journal of Human-Computer Interaction. 1989. vol. 1: pp. 69-107 : ill. includes bibliography
summary	This paper describes the development and application of a cognitively-based performance methodology for assessing human performance on computer-aided architectural design (CAAD) tasks. Two CAAD tasks were employed that were hypothesized to be different in terms of the underlying cognitive processes required for these tasks to be performed. Methods of manipulating task complexity within each of these tasks were then developed. Six architectural graduate students were trained on a commercially available CAAD system. Each student performed the two experimental design tasks at one of three levels of complexity. The data collected included protocols, video recordings of the computer screen, and an interactive script (time-stamped record of every command input and the computers textual response). Performance measures and methods of analysis were developed which reflected the cognitive processes used by the human during design (including problem- solving techniques, planning times, heuristics employed, etc.) and the role of the computer as a design aid. The analysis techniques used included graphical techniques, Markov process analysis, protocol analysis, and error classification and analysis. The results of the study indicated that some measures more directly reflected human design activity while others more directly reflected the efficiency of interaction between the computer and the human. The discussion of the results focuses primarily on the usefulness of the various measures comprising the performance methodology, the usefulness of the tasks employed including methods for manipulating task complexity, and the effectiveness of this system as well as CAAD systems in general for aiding human design processes

source	The Electronic Design Studio: Architectural Knowledge and Media in the Computer Era [CAAD Futures ‘89 Conference Proceedings / ISBN 0-262-13254-0] Cambridge (Massachusetts / USA), 1989, pp. 363-376
summary	The capacity of most computer-aided design systems is inadequate to represent landscape architectural ideas and compute landscape scenes quickly. As part of our teaching agenda, we decided to write software for the Silicon Graphics Iris workstations to tackle this problem directly. This paper begins with a discussion of our concerns about the use of CAD tools in the representation of landscape architectural space. Secondly, we discuss the approach that Toronto takes to computing and teaching with particular emphasis on the use of computers to support an integrated representational work environment. Finally, a fourth-year design studio that used our software is reviewed. Static illustrations of the system are presented here, although there is a videotape that demonstrates the dynamic nature of the system.

title	The structure and function of diagrams in environmental design :a computational inquiry
source	Massachusetts Institute of Technology
summary	The design process often begins with a graphical description of the proposed device or system and sketching is the physical expression of the design engineer's thinking process. Computer Aided Design is a technique in which man and machine are blended into a problem solving team, intimately coupling the best characteristics of each. Solid modelling is developed to act as the common medium between man and the computer. At present it is achieved mainly by designing with volumes and hence does not leave much room for sketching input, the traditional physical expression of the thinking process of the design engineer. This thesis describes a method of accepting isometric free hand sketching as the input to a solid model. The design engineer is allowed to make a sketch on top of a digitizer indicating (i) visible lines; (ii) hidden lines; (iii) construction lines; (iv) centre lines; (v) erased lines; and (vi) redundant lines as the input. The computer then processes this sketch by identifying the line segments, fitting the best possible lines, removing the erased lines, ignoring the redundant lines and finally merging the hidden lines and visible lines to form the lines in the solid in an interactive manner. The program then uses these lines and the information about the three dimensional origin of the object and produces three dimensional information such as the faces, loops, holes, rings, edges and vertices which are sufficient to build a solid model. This is achieved in the following manner. The points in the sketch are first written into a file. The computer than reads this file, breaks the group of points into sub-groups belonging to individual line segments, fits the best lines and identify the vertices in two dimensions. These improved lines in two dimensions are then merged to form the lines and vertices in the solid. These lines are then used together with the three dimensional origin (or any other point) to produce the wireframe model in three dimensions. The loops in the wireframe models are then identified and surface equations are fitted to these loops. Finally all the necessary inputs to build a B-rep solid model are produced.

summary	This paper tackles the problem of the functional and morphological definition of elementary spaces (in relation to the overall definition of the building object) through the study and the modelization of the designer's knowledge and of the cognitive processes which use it. An interactive automatic system which solves the problem of the placing of objects within a predefined environment is then described. This is the first element in a more general system which is meant as an intelligent aid to building design.

summary	The present paper outlines a plan for the teaching of architectural composition with computer assistance.The approach is to introduce students to a series of architectural languages characterized by a vocabulary of elements and a grammar whose rules indicate how these elements can be placed in space. Exercises with each language include the analysis of precedents; the generation of forms using a given rule set; and follow-up studies with an expanded rule set. The paper introduces languages and exercises through illustrative examples. This architectural content can be taught in the traditional way. The use of computers is motivated by expectations which are stated, and some basic requirements for the needed software are listed. Work to develop this software has started.

summary	While the development of modelling and drafting tools for computer-aided design has reached a state of considerable maturity, computerized decision support in architectural sketch design is still in its infancy after more than 20 years. The paper analyzes the difficulties of developing computer tools for architectural problem solving in the early stages of design where decisions of majors importance are made. The potentials of computer methods are discussed in relation to design as a static system of information, and to design as a creative process. Two key problems are identified, and on this background current computer methods intended for use in architectural sketch design are critically reviewed. As a result some guidelines are suggested for future research into computer-aided architectural problem solving. The purpose of the paper is twofold: (1) to encourage research that will take this field into a state of maturity and acceptance by practitioners, and (2) to provoke further debate on the question of how to do it

title	Expert Systems in Engineering, Architecture and Construction
source	360 p University of Sydney: 1989. CADLINE has abstract only.
summary	Engineering involves both cognitive and calculational processes. It involves judgement as well as numeracy. Cognitive processes and judgement are better served by expert systems than other existing technologies. Expert systems are not designed to replace technologies currently used in engineering, rather they are and will continue to augment them. Clearly, better tools are needed and further education of engineers is needed. This conference aims to provide a forum for the presentation of developments and applications of expert systems in engineering, primarily in Australasia. The 20 papers accepted for presentation span the spectrum of engineering applications of expert systems from analysis and diagnosis, through simulation and modeling, learning, to design and synthesis

title	Relational Modeling: A Basis for Computer-Assisted Design

summary	Today's computer assisted design (CAD) systems automate traditional ways of working with tracing paper and pencil, but they cannot represent the rules and relationships of a design. As hardware becomes faster and memory less expensive, more sophisticated fundamental software technologies will be adopted. This shift in the basis of CAD will provide powerful capabilities and offer new ways to think about designing. Recently parametric design, a technique for describing a large class of designs with a small description in code, has become a focus of attention in architectural computing. In parametric CAD systems, design features are identified and keyed to a number of input variables. Changes in the input values result in variations of the basic design. Based on conventional software technologies, parametric design has been successfully applied in many design domains including architecture and is supported by several commercial CAD packages. A weakness of parametric techniques is the need to predetermine which properties are input parameters to be varied and which are to be derived. Relational modeling is a simple and powerful extension of parametric design that overcomes this weakness. By viewing relations as reversible rather than one-way, any set of properties can be chosen as input parameters. For example, a relational model that calculates the shadow length of a given building can also be used to calculate the building height given a desired shadow length. In exercising a relational model the designer is not limited to a pre-selected set of input variables but can explore and experiment freely with changes in all parts of the model. Co is a relational modeling environment under development on the Macintosh-II computer, and Co-Draw, a prototype CAD program based on Co. Co's relationaI engine and object-oriented database provide a powerful basis for modeling design relations. Co-Draw's interactive graphics offer a flexible medium for design exploration. Co provides tools for viewing and editing design models in various representations, including spreadsheet cards, tree and graph structures, as well as plan and elevation graphics. Co's concepts and architecture are described and the implications for design education are discussed.

summary	The use of technology has grown with the way design professions have evolved over time. Changing needs, desires of comfort, and perceptions of the consumers have led to a distinct improvement in the design of both product and architecture. The use of the digital media and emerging technologies has brought a dramatic change to the design process allowing us to view, feel, and mould a virtual object at every stage of design, development, and engineering. Change is often quick and easy since a virtual product does not inherently carry the biases of its physical counterpart. In order to communicate ideas across the team, digital processes are also used to bring together opinions, experiences, and perspectives. These methods encourage decision making based on information rather than prejudice or instinct. Thus, digital exchanges (technology) impact firm strategies at three levels: product, process, and administrative or support activities (Adler 1989).Digital tools for design exchange in Industrial Design (ID) began much earlier than many other professions. The profession of Architecture is also slowly moving to a similar model with digital exchange finding increasing prevalence in drawing, modeling, performance simulation, design collaboration, construction management, and building fabrication. The biggest problem is the disintegrated use of technology in the architectural profession without a strategy toward streamlining the design process from conception to fabrication. In this paper we investigate how the use of technology has evolved in the professions of Industrial Design and Architecture comparatively in their product, process, and support activities. Further, we will present a set of guidelines that will help architects in the convergence of design process, helping in a more efficient work flow with a strategic use of digital technology.

summary	This research has shown the difficulties associated with the GIS and the flooding evacuation path search through the huge searching space generated during the network analysis process. This research also presents an approach to these problems by utilizing a search process whose concept is derived from natural genetics. Genetic algorithms (GAs) have been introduced in the optimization problem solving area by Holland (1975) and Goldberg (1989) and have shown their usefulness through numerous applications. We apply GA and GIS to choice flooding evacuation path in metropolitan area in this study. We take the region of Shiji city in Taiwan for case. That could be divided into four parts. First, is to set the population of GA operation. Second, is to choose crossover and mutation. Third, is to calculate the fitness function of each generation and to select the better gene arrangement. Fourth, is to reproduce, after evolution, we can establish Flooding Evacuation Path that more reflect really human action and choice when flood takes place. However we can apply GA to calculate different evacuation path in different time series. Final, we compare and establish real model of evacuation path model to choosing flooding evacuation path.
