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.

title	A Case Study in Knowledge-Based System Development : Envelope Design for Reduction of Traffic Noise Transmission
source	February, 1990. 19 p. : some ill. and table. includes a bibliography
summary	Researchers have demonstrated the value of replication of research and explicit testing of concepts in artificial intelligence (Ritchie and Hanna 1989). In this study, a rule- based system was implemented as an exercise in the application of the theory and practice of knowledge-based systems development to architectural design analysis. The test domain was the selection of wall and window assemblies to provide adequate noise reduction given a set of traffic and building site conditions. This domain was chosen for two reasons: (1) considerable detailed heuristic information was available; and (2) it avoided large solutions spaces, 'errorful' and time-dependent data, and unreliable knowledge. Development of the system in conjunction with an extensive literature review revealed that publications on construction and performance of rule-based systems provided insufficient detail on key aspects of system architecture. Topics suffering from neglect or insufficiently rigorous treatment included algorithms used in automated inference, methods for selection of inference procedures, the integration of numerical and symbolic processing, the formulation of explanation mechanisms to deal with integrated numerical and symbolic processing, testing methods, and software standardization. Improving the quality and scope of knowledge in these areas is essential if expert systems are to be applied effectively in architectural design

summary	Because of the special geography features and subtropics weather in Taiwan, we need to provide correct information to help people making decision when they are in disaster. So the disaster decision support system must offer proper information of evacuation path to people. 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. Firstly, we establish the node relationship of GA calculation, the level of the weight is the standard of the date that is exported by Disaster Database. Secondly, we apply GA to calculate different evacuation path in different time series. Finally, we build the model of choosing flooding evacuation path.

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
source	CAAD: Education - Research and Practice [eCAADe Conference Proceedings / ISBN 87-982875-2-4] Aarhus (Denmark) 21-23 September 1989, pp. 8.3.1.8.3.10
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.

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 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	Computer Integrated Design: Transformation as Process

summary	To bring together poetry, magic and science, to explore beyond preconceptions, to invent spaces and forms which re-form and inform man's experience, these are the possibilities of architecture. Computer integrated design offers a means for extending the search, one which integrates both conceptual and perceptual issues in the making of architecture. The computer may assist in generating constructs which would not have been created by conventional methods. The application of computer techniques to design has to date been focused primarily on production aspects, an area which is already highly organizable and communicable. In conceptual and perceptual aspects of design, computer techniques remain underdeveloped. Since the impetus for- the development of computer applications has come from the immediate economics of practice rather than a theoretically based strategy, computer-aided design is currently biased toward the replication of conventional techniques rather than the exploration of new potentials. Over the last two years we have been involved in experimentation with methodologies which engage the computer in formative explorations of the design idea. Work produced from investigations by 4th and 5th year undergraduate students in computer integrated design studios that we have been teaching at the University of Southern California demonstrates the potential for the use of the computer as a principal tool in the exploration of syntax and perception, space and program. The challenge is to approach the making of architecture as an innovative act, one which does not rely on preconceived notions of design.

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

summary	Conventional computer systems currently used by architecture and landscape architecture are not addressing complex decision making, system interface, dynamic manipulation and real time visualization of data. This paper identifies a strategy by which Canadian Schools could form a supportive network, incorporate and expand their research development. Within this larger framework schools would have better tools, a larger research base and access to funding as a group. The following discussion is an idea of what we at the Canadian Schools need to do differently over the next five years in our research and teaching in order to make a unique contribution to our fields.

source	Engineering Design Research Center, CMU, Pittsburgh, PA, USA
summary	As VLSI design frameworks evolve, a distributed control mechanism for CAD tools has become a central research issue. In this paper, we present an object oriented tool integration methodology that treats the tools as objects. This approach simplifies CAD tool control within a design framework making the framework more general, easier to use, and more capable of supporting a large population of CAD tools.

title	Messina 1908: The Invisible City
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. 239-246
summary	The initial purposes of this work were to build a 3D model of the old city of Messina and to reconstruct a walk through it; to understand the "Ghost city," the parts that form it, and the rules of its plan, which are explicit in some cases but hidden most of the time; to measure its space, appreciate the similarities to and differences from modern city plans, and use the information to improve the plans of tomorrow. It might seem a useless study of a nonexistent city, and yet during the months of detailed work, of patient reconstruction from the surveys and photographs of the city destroyed in 1908, we began to consider how it was still possible to obtain spatial values of and to project behaviors in the lost city, in other words, to practice tests on memory that are very interesting for people working in a context in which memory no longer exists. The work presented here is the first stage of a more complex research project still to be carried out on Messina as it was at the end of the nineteenth century. Here we constructed a 3D model of some parts of the city prior to the earthquake of 1908 and made a five-minute video, using cartoon techniques, of an "impossible" walk through the city. The fragments of the city were reconstructed from available documentary sources, primarily photographic images, which tended to be of the most important places in the city.

doi	https://doi.org/10.52842/conf.ecaade.1989.x.u3h
source	CAAD: Education - Research and Practice [eCAADe Conference Proceedings / ISBN 87-982875-2-4] Aarhus (Denmark) 21-23 September 1989, pp. 7.3.1-7.3.9
summary	The paper presents a study aimed at the modelization of a design operation of perturbation of an architectural framework in order to comply with a series of given design specifications. A formalized representation of the building object is assumed, Artificial Intelligence techniques are adopted to work on it. It is assumed that the computer carries out deformations starting from one of these structures in order to attain to a solution consistent with project specifications. A description of the structures employed for the representation of the building body (matroids) is firstly proposed. A planning theme is then assumed, as an example, whose main feature is to maintain the outer perimeter of a dwelling, to change its internal distribution in such a way as to resemble as closely as possible to the original and yet meaningfully alter its typology.

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.

title	SEED: A Software Environment to Support the Early Phases in Building Design
source	Proceeding of IKM '94, Weimar, Germany, pp. 5-10
summary	The SEED project intends to develop a software environment that supports the early phases in building design (Flemming et al., 1993). The goal is to provide support, in principle, for the preliminary design of buildings in all aspects that can gain from computer support. This includes using the computer not only for analysis and evaluation, but also more actively for the generation of designs, or more accurately, for the rapid generation of design representations. A major motivation for the development of SEED is to bring the results of two multi-generational research efforts focusing on `generative' design systems closer to practice: 1. LOOS/ABLOOS, a generative system for the synthesis of layouts of rectangles (Flemming et al., 1988; Flemming, 1989; Coyne and Flemming, 1990; Coyne, 1991); 2. GENESIS, a rule-based system that supports the generation of assemblies of 3-dimensional solids (Heisserman, 1991; Heisserman and Woodbury, 1993). The rapid generation of design representations can take advantage of special opportunities when it deals with a recurring building type, that is, a building type dealt with frequently by the users of the system. Design firms - from housing manufacturers to government agencies - accumulate considerable experience with recurring building types. But current CAD systems capture this experience and support its reuse only marginally. SEED intends to provide systematic support for the storing and retrieval of past solutions and their adaptation to similar problem situations. This motivation aligns aspects of SEED closely with current work in Artificial Intelligence that focuses on case-based design (see, for example, Kolodner, 1991; Domeshek and Kolodner, 1992; Hua et al., 1992).

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. 31-48
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	The School of Architecture at Lund Institute of Technology was augmented by the establishment of the Computer Studio in 1987. As a result the school now has a device for teaching and research in the architects' use of computers. We are now conducting several research projects as well as courses and an education project. The third and fourth years of the education at the school of architecture are arranged as education projects instead of traditional lecturing. The students choose from projects that are organised by different departments at the School of Architecture. The issue is that the students will ask for instruction when felt needed, and that learning will therefore be more efficient. The Computer Studio has conducted such a project during the first half of 1989. We have tried to encourage the students to use our different computers and programs in new and creative ways. One of the issues of the computer project is to teach the students how computers are used at the architects offices today as well as expected future developments. The students shall be acquainted well enough with present and future possibilities to make good choices when deciding upon buying computers for architectural use. Another issue is to develop new ways of making and presenting architecture by using computers. As a group the teachers at the school of architecture have a very restrictive attitude towards the use of computers. We hope that our project will open their minds for the possibilities of computers, and to engage them in the development of new ways to use computers creatively in architecture. An interesting question is if the use of computers will yield different outcomes of he students' work than traditional methods. An object for research is whether the added possibilities of considering different aspects of he design by using a computer will make for higher quality of the results.

title	Integrating Microcomputer CADr and Bill of Material Routines Using AutoCad
doi	https://doi.org/10.52842/conf.ecaade.1989.x.r8o
source	CAAD: Education - Research and Practice [eCAADe Conference Proceedings / ISBN 87-982875-2-4] Aarhus (Denmark) 21-23 September 1989, pp. 9.2.1-9.2.10
summary	Through the integration of microcomputer-aided draughting (CADr), and in particular with AutoCAD, the industries most extensively used CADr program, and automated routines for the production of bills of materials, a dramatic incr-ease in productivity is possible in the architectural design domain. Working from a variety of material take off methods complete cost estimates may be achieved through the manipulation of drawing data and exchanging the information with third-party estimating software. However, the area of study is currently at a formative stage of development and full integration, although technically feasible, is rarely attempted. Therefore, the paper comments on the development of 'in-house' routines using AutoCAD's data extraction features and AutoLISP; reviews current commercial systems of interfacing AutoCAD with bills of materials and automated specification routines; and, finally, discusses possible future advances in this major area of study.

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.

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.
