summary An approach is presented for defining the information needed or used in a design task, based on data modeling techniques. Called EDM, it allows representation of the information complexity imposed both from the performances or technologies involved as well as imposed criteria, such as aesthetic intentions. Here, EDM is applied to the design of chairs, a design domain with highly diverse technologies and information structures. The relation is shown between the information considered and the class of designs possible. Also shown is the complexity of different design structures and the implication of information structures for conventional and creative design.

title ICAtect: Integrating Design Tools for Preliminary Architectural Design
source Wellington, New Zealand: Computer Science Department, Victoria University
summary ICAtect is a knowledge based system that provides an interface between expert systems, simulation packages and CAD systems used for preliminary architectural design. This thesis describes its structure and development.The principal work discussed in this thesis involves the formulation of a method for representing a building. This is developed through an examination of a number of design tools used in architectural design, and the ways in which each of these describe a building.Methods of enabling data to be transferred between design tools are explored. A Common Building Model (CBM), forming the core of the ICAtect system, is developed to represent the design tools knowledge of a building. This model covers the range of knowledge required by a large set of disparate design tools used by architects at the initial design stage.Standard methods of integrating information from the tools were examined, but required augmentation to encompass the unusual constraints found in some of the design tools. The integration of the design tools and the CBM is discussed in detail, with example methods developed for each type of design tool. These example methods provide a successful way of moving information between the different representations. Some problems with mapping data between very different representations were encountered in this process, and the solutions or ideas for remedies are detailed. A model for control and use of ICAtect is developed in the thesis, and the extensions to enable a graphical user interface are discussed.The methods developed in this thesis demonstrate the feasibility of an integrated system of this nature, while the discussion of future work indicates the scope and potential power of ICAtect.

title A digital Procedure of Building Construction: A practical project

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 The Limitations of Current Working Practices on the Development of Computer Integrating Modelling in Construction
source computer Integrated Future, CIB W78 Seminar. Calibre, The Netherlands: Eindhoven University of Technology, september, 1991. Unnumbered. includes bibliography
summary For the construction Industry to improve its processes through the application computer-based systems, traditional working practices must first change to support the integrated control of design and construction. Current manual methods of practice accept the limitations of man to process a wide range of building performance and production information simultaneously. However when these limitations are removed, through the applications of computer systems, the constraints of manual methods need no longer apply. The first generation of computer applications to the Construction Industry merely modelled the divided and sequential processes of manual methods i.e. drafting, specification writing, engineering and quantity calculations, estimating, billing, material ordering data-bases and activity planning. Use of these systems raises expectations that connections within the computer between the processes modelled can actually be made and faster and more integrated information processing be achieved. 'Linking' software is then developed. The end result of this approach was that users were able to produce information faster, present it in an impressive manner but, in reality, no perceived improvement in actual building performance, production economy or efficiency was realized. A current government sponsored Teaching Company Programme with a UK design and build company is addressing the problem of how real economic benefit can be realized through improvement in, amongst other things, their existing computer applications. This work is being carried out by both considering an academic conceptual model of how 'designing for production' can be achieved in computer applications and what is immediately realizable in practice by modelling the integration of a limited number of knowledge domains to which computers are already being applied. i.e. billing from design, estimating and buying. This paper describes each area of work and how they are impacting on each other

title Dynamic Information System for Modelling of Design Processes
source Computer Integrated Future, CIB W78 Seminar. september, 1991
summary Unnumbered : ill. DINAMO is a Dynamic Information System for Modelling of Design Processes. It is intended for use along with product models, data management systems and existing applications. In DINAMO a programming user can define processes. These processes are represented by graphs. The graphs are characterized by nodes and relations between nodes. Each node in a graph represents a task, and each relation can be restricted to conditions. So the way in which a process is actually being performed, that is, the actual path to be evaluated through the graph, can depend on certain conditions. Processes and functions (=software modules) are available to the user as tasks. A consuming user can activate tasks; the DINAMO system regulates the dispatch of the tasks, conform the process and function definitions. Tasks are collected on sheets; sheets are collected in a task box. A task box can be regarded as a certain environment, determined by the programming user. A consuming user can choose between the environments which are available at that moment. With the DINAMO system software and process definitions can be re-used in a simple way

summary Until now, books on CAD aimed at architects have addressed the use of computer-aided design and drafting as a recording tool, a faster means of producing and storing finished working drawings-and not as an adjunctive creative tool for the design process. Without being software specific, this book will guide the professional and student architect and graphics designer in how to use the computer as an electronic modelling tool, exploring graphic and geometric forms and systems with the freedom and speed of the computer. The reader will be led through a progression of design exercises and design problems, learning how to come up with multiple solutions to a given program.

title BECOC : A Knowledge Bank and its Use in Construction and CAD Systems
source The Computer Integrated Future, CIB W78 Seminar. September, 1991. Unnumbered : ill. include some bibliographical references
summary The Development of the BECOC prototype (Structured Knowledge Bank for Construction Elements) was undertaken in order to test the integration of Data and Knowledge using the SITEC model (Construction Technology Information System). After the graphical definition of a building exterior, the assignment of the construction solutions is dynamically controlled using the Knowledge Bank for real time decision making. To represent the knowledge that acts on the data the knowledge bank consists of an Object Oriented Data Base and a Rule System, developed using the NEXPERT/OBJECT package. In this manner it is possible to establish relationships among properties, concepts, restrictions in values, structural relations and the control of standards compliance, which in this case has been limited to thermal, acoustic and weight requirements. The system helps the user to make decisions and it analyzes the context in order to make the deductions needed to maintain internal data consistency. The positive results of this work indicate the way for further developments, and demonstrate that expert systems and traditional technologies coupled together can be effective and give the desired answers in monitoring design in the everyday problems in construction technology

title The Vector-drawing as a Means to Unravel Architectural Communication in the Past
source [eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
doi https://doi.org/10.52842/conf.ecaade.1993.x.q9a
summary Unlike in painting, in architecture one single person never controls the whole process between conception and realization of a building. Ideas of what the building will eventually look like, have to be conveyed from patron to the actual builders, by way of drawings. Generally the architect is the key-figure in this process of communication of visual ideas. Nowadays many architects design their new buildings by using computers and Computer-Aided (Architectural) Design programs like AutoCad and VersaCAD. Just like traditional drawings, all these computer drawings are in fact vector-drawings; a collection of geometrical primitives like lines, circle segments etc. identified by the coordinates of their end points. Vector-based computer programs can not only be used to design the future, but also as a means to unravel the architectural communication in the past. However, using the computer as an analyzing tool for a better comprehension of the past is not as simple as it seems. Historical data from the past are governed by unique features of date and place. The complexity of the past combined with the straightforwardness of the computer requires a pragmatic and basic approach in which the computer acts as a catalytic agent, enabling the scholar to arrive manually at his own - computer-assisted - conclusions. From this it turns out that only a limited number of projects of a morphological kind are suited to contribute to new knowledge, acquired by the close-reading of the information gained by way of meaningful abstraction. An important problem in this respect is how to obtain the right kind of architectural information. All four major elements of the building process - architect, design, drawing and realization - have their own different and gradually shifting interpretations in the past. This goes especially for the run-of-the-mill architecture which makes up the larger part of the historical urban environment. Starting with the architect, one has to realize that only a very limited part of mainstream architecture was designed by architects. In almost all other cases the role of the patron and the actual builder exceeds that of the architect, even to the extent that they designed buildings themselves. The position of design and drawing as means of communication also changed in the past. Until the middle of the nineteenth century drawings were not the chief means of communication between architects and builders, who got the gist of the design from a model, or, encountering problems, simply asked the architect or supervisor. From the nineteenth century onwards the use of drawings became more common, but almost never represented the building entirely "as built". In 1991 I published my Ph.D. thesis: Constructing the past: computerassisted architectural-historical research: the application of image-processing using the computer and Computer-Aided Design for the study of the urban environment, illustrated by the use of treatises in seventeenth-century architecture (Utrecht 1991). Here, a reconstruction of this historical communication process will be presented on the basis of a project studying the use of the Classical orders as prescribed in various architectural treatises, compared to the use of the orders in a specific group of still existing buildings in The Netherlands dating from the late sixteenth and entire seventeenth century. Comparisons were made by using vector-drawings. Both the illustrations in the the treatises and actual buildings were "translated" into computer-drawings and then analyzed.

title Imagining Light: A Visualization of Daylighting Data
source Computer Aided Architectural Design Futures: Education, Research, Applications [CAAD Futures ‘91 Conference Proceedings / ISBN 3-528-08821-4] Zürich (Switzerland), July 1991, pp. 97-104
summary The task of designing effective lighting for buildings requires both artistic and technical competence. In this way it is archetypical of the discipline of architectural design. The interaction of buildings with solar lighting is complex and ever-changing. Added complexity comes with the use of electric lights and their daylight-sensitive control systems. State-of-the-art daylight prediction tools most often provide precision data that is in obscure numerical formats hindering the communication and perception of information hidden within. We are exploring the use of scientific visualization to transform incomprehensible tables of data into images that visually oriented designers will find more accessible. By representing lighting data and their interactions with the environment visually, students and design professionals may be able to "imagine the light" in ways that will help them understand and solve complex lighting design problems.

title A Common Data Model for Computer Integrated Building
source computer Integrated Future, CIB W78 Seminar. September, 1991. Unnumbered : some ill. includes bibliography
summary The connection of various building performance evaluation tools in a collaborative way is an essential request to develop true CAD systems. It is a basic requirement for the future of integrated information systems for building projects, where data concerning multiple aspects of the project can be exchanged during the different design steps. This paper deals with the on-going research concerning the generation of a common data model in the framework of a European collaborative action, the COMBINE Project, which is supported by the CEC, General Directorate XII for Research Science and Development, within the JOULE programme. The first step of the research concerns the progressive construction of a conceptual model and the paper focuses on the development of this Integrated Data Model (IDM). The paper reports on the definition of the architecture of the IDM. The main issues and the methodology of the IDM development are presented. The IDM development methodology is based on successive steps dealing with the identification of the data and context which are considered by the Design Tool Prototypes (DTP) to be connected through the IDM, the conceptual integration of this knowledge, and the implementation of the model on an appropriate software environment

This conceptual model is formed by extending the Finnish RATAS building product data model to include also construction activities, resources, costs, organizations, contracts, etc. and relationships between them. The overall conceptual framework model can be used to extract conceptual submodels related to the information needs of particular participants of the construction process. As an example of different views to design and construction information the views of design, cost estimating and production planning discussed in the paper.

summary In the field of architectural design, “visualization¨ generally refers to some media, communicating and representing the idea of designers, such as ordinary drafts, maps, perspectives, photos and physical models, etc. (Rahman, 1992; Susan, 2000). The main reason why we adopt visualization is that it enables us to understand clearly and to control complicated procedures (Gombrich, 1990). Secondly, the way we get design knowledge is more from the published visualized images and less from personal experiences (Evans, 1989). Thus the importance of the representation of visualization is manifested.Due to the developments of computer technology in recent years, various computer aided design system are invented and used in a great amount, such as image processing, computer graphic, computer modeling/rendering, animation, multimedia, virtual reality and collaboration, etc. (Lawson, 1995; Liu, 1996). The conventional media are greatly replaced by computer media, and the visualization is further brought into the computerized stage. The procedure of visual impact analysis and assessment (VIAA), addressed by Rahman (1992), is renewed and amended for the intervention of computer (Liu, 2000). Based on the procedures above, a great amount of applied researches are proceeded. Therefore it is evident that the computer visualization is helpful to the discussion and evaluation during the design process (Hall, 1988, 1990, 1992, 1995, 1996, 1997, 1998; Liu, 1997; Sasada, 1986, 1988, 1990, 1993, 1997, 1998). In addition to the process of architectural design, the computer visualization is also applied to the subject of construction, which is repeatedly amended and corrected by the images of computer simulation (Liu, 2000). Potier (2000) probes into the contextual research and restoration of historical architecture by the technology of computer simulation before the practical restoration is constructed. In this way he established a communicative mode among archeologists, architects via computer media.In the research of restoration and preservation of historical architecture in Taiwan, many scholars have been devoted into the studies of historical contextual criticism (Shi, 1988, 1990, 1991, 1992, 1995; Fu, 1995, 1997; Chiu, 2000). Clues that accompany the historical contextual criticism (such as oral information, writings, photographs, pictures, etc.) help to explore the construction and the procedure of restoration (Hung, 1995), and serve as an aid to the studies of the usage and durability of the materials in the restoration of historical architecture (Dasser, 1990; Wang, 1998). Many clues are lost, because historical architecture is often age-old (Hung, 1995). Under the circumstance, restoration of historical architecture can only be proceeded by restricted pictures, written data and oral information (Shi, 1989). Therefore, computer simulation is employed by scholars to simulate the condition of historical architecture with restricted information after restoration (Potier, 2000). Yet this is only the early stage of computer-aid restoration. The focus of the paper aims at exploring that whether visual simulation of computer can help to investigate the practice of restoration and the estimation and evaluation after restoration.By exploring the restoration of historical architecture (taking the Gigi Train Station destroyed by the earthquake in last September as the operating example), this study aims to establish a complete work on computer visualization, including the concept of restoration, the practice of restoration, and the estimation and evaluation of restoration.This research is to simulate the process of restoration by computer simulation based on visualized media (restricted pictures, restricted written data and restricted oral information) and the specialized experience of historical architects (Potier, 2000). During the process of practicing, communicates with craftsmen repeatedly with some simulated alternatives, and makes the result as the foundation of evaluating and adjusting the simulating process and outcome. In this way we address a suitable and complete process of computer visualization for historical architecture.The significance of this paper is that we are able to control every detail more exactly, and then prevent possible problems during the process of restoration of historical architecture.

title Design Tool Integration: Model Flexibility for the Building Profession
source Proceedings of Building Systems Automation - Integration, University of Wisconsin-Madison
summary The development of ICAtect, as discussed in the Building Systems Automation and Integration Symposium of 1991, provides a way of integrating simulation tools through a common building model. However, ICAtect is only a small step towards the ultimate goal of total integration and automation of the building design process. In this paper we investigate the next steps on the path toward integration. We examine how models structured to capture the physical attributes of the building, as required by simulation tools, can be used to converse with knowledge-based systems. We consider the types of mappings that occur in the often different views of a building held by these two classes of design tools. This leads us to examine the need for multiple views of a common building model. We then extend our analysis from the views required by simulation and knowledge-based systems, to those required by different segments of the building profession (e.g. architects, engineers, developers, etc.) to converse with such an integrated system. This indicates a need to provide a flexible method of accessing data in the common building model to facilitate use by different building professionals with varying specialities and levels of expertise.

title ABLOOS : an evolving hierarchical design framework
source Carnegie Mellon University, Department of Architecture
summary The research reported in this thesis develops an approach toward a more effective use of hierarchical decomposition in computational design systems. The approach is based on providing designers a convenient interactive means to specify and experiment with the decompositional structure of design problems, rather than having decompositions pre-specified and encoded in the design system. Following this approach, a flexible decomposition capability is combined with an underlying design method to form the basis for an extensible and evolving framework for cooperative (humdcomputer) design. As a testbed for this approach, the ABLOOS framework for layout design is designed and constructed as a hierarchical extension of LOOS.’The framework enables a layout task to be hierarchically decomposed, and for the LOOS methodology to be applied recursively to layout subtasks at appropriate levels of abstraction within the hierarchy; layout solutions for the subtasks are then recomposed to achieve an overall solution, Research results thus far are promising: ABLOOS has produced high quality solutions for a class of industrial layout design tasks (an analog power board layout with 60 components that have multiple complex constraints on their placement); the adaptability of the framework across domains and disciplines has been demonstrated; and, further development of ABLOOS is underway including its extension to layouts in 2 1/2D space and truly 3D arrangements. The contribution of this work is in demonstrating an effective, flexible and extensible capability for hierarchical decomposition in design. It has also produced a more comprehensive layout system that can serve as a foundation for the further investigation of hierarchical decomposition in a variety of design domains.

title Handbook of genetic algorithms
source Van Nostrand Reinhold, New York
summary This book sets out to explain what genetic algorithms are and how they can be used to solve real-world problems. The first objective is tackled by the editor, Lawrence Davis. The remainder of the book is turned over to a series of short review articles by a collection of authors, each explaining how genetic algorithms have been applied to problems in their own specific area of interest. The first part of the book introduces the fundamental genetic algorithm (GA), explains how it has traditionally been designed and implemented and shows how the basic technique may be applied to a very simple numerical optimisation problem. The basic technique is then altered and refined in a number of ways, with the effects of each change being measured by comparison against the performance of the original. In this way, the reader is provided with an uncluttered introduction to the technique and learns to appreciate why certain variants of GA have become more popular than others in the scientific community. Davis stresses that the choice of a suitable representation for the problem in hand is a key step in applying the GA, as is the selection of suitable techniques for generating new solutions from old. He is refreshingly open in admitting that much of the business of adapting the GA to specific problems owes more to art than to science. It is nice to see the terminology associated with this subject explained, with the author stressing that much of the field is still an active area of research. Few assumptions are made about the reader's mathematical background. The second part of the book contains thirteen cameo descriptions of how genetic algorithmic techniques have been, or are being, applied to a diverse range of problems. Thus, one group of authors explains how the technique has been used for modelling arms races between neighbouring countries (a non- linear, dynamical system), while another group describes its use in deciding design trade-offs for military aircraft. My own favourite is a rather charming account of how the GA was applied to a series of scheduling problems. Having attempted something of this sort with Simulated Annealing, I found it refreshing to see the authors highlighting some of the problems that they had encountered, rather than sweeping them under the carpet as is so often done in the scientific literature. The editor points out that there are standard GA tools available for either play or serious development work. Two of these (GENESIS and OOGA) are described in a short, third part of the book. As is so often the case nowadays, it is possible to obtain a diskette containing both systems by sending your Visa card details (or $60) to an address in the USA.

summary What a Difference a Tool Makes : discoveries made during the evolution of the Advanced Design Studio (a.k.a. 'working drawings') at the University of Texas at Austin since the time this core course was switched to computers, when student design teams were provided with computers and required to use them for design and presentation. Covers the period from the course?s inception in 1991 to the present, during which the course has been under the continuing aegis of Professor Richard Dodge, who has taught design since 1967. Contrapuntal presentation by Professor Dodge and co-instructor and former student Marla Smith: what was done, what worked, and what went wrong. Discusses students, faculty, hardware, software, design problems assigned, and the most educational computer-related catastrophes.

summary The need to explore development techniques in computer-based design is reviewed. Some premises are given for design development using computers, including integrating multiple representations, the use of object-based modeling and the importance of visual analysis and 3-D modeling. We then present techniques used in a UCLA design studio that explored methods of computer-based design development based on these premises. The two main methods used were hierarchical object structures and multi-representational coordination. They were applied using conventional CAD systems. Some lessons learned from this class are reviewed.

summary The concept of ODE (Open Design Environment) and corresponding system were presented in 1991. Then the new concept of NODE. which is networked version of ODE. was generated to make wide area collaboration in 1994. The aim of our research is to facilitate the collaboration among the various people involved in the design process of an urban or architectural project. This includes various designers and engineers, the client and the citizens who may be affected by such a project. With the new technologies of hyper medium, network, and component architecture, we have developed NODE system and applied in practical use of the collaboration among the various people. This study emphasizes the interactive 3-D design tool of NODE which is able to make realistic and realtime presentation with interactive interface. In recent years, ProjectFolder of NODE system, which is a case including documents, plans, and tools to proceed project., is created in the World Wide Web (WWW) and makes hyper links between a 3-D object and a text, an image. and other digital data.
