summary	Several studies have discussed the limitations of the available CAAD tools and have proposed solutions [Brown and Novitski 1987, Brown 1990, Degelman and Kim 1988, Schuman et al 1988]. The lack of integration between the different tasks that these programs address and the design process is a major problem. Schuman et al [1988] argued that in architectural design many issues must be considered simultaneously before the synthesis of a final product can take place. Studies by Brown and Novitski [1987] and Brown [1990] discussed the difficulties involved with integrating technical considerations in the creative architectural process. One aspect of the problem is the neglect of technical factors during the initial phase of the design that, as the authors argued, results from changing the work environment and the laborious nature of the design process. Many of the current programs require the user to input a great deal of numerical values that are needed for the energy analysis. Although there are some programs that attempt to assist the user by setting default values, these programs distract the user with their extensive arrays of data. The appropriate design tool is the one that helps the user to easily view the principal components of the building design and specify their behaviors and interactions. Data abstraction and information parsimony are the key concepts in developing a successful design tool. Three different approaches for developing an appropriate CAAD tool were found in the literature. Although there are several similarities among them, each is unique in solving certain aspects of the problem. Brown and Novitski [1987] emphasize the learning factor of the tool as well as its highly graphical user interface. Degelman and Kim [1988] emphasize knowledge acquisition and the provision of simulation modules. The Windows and Daylighting Group of Lawrence Berkeley Laboratory (LBL) emphasizes the dynamic structuring of information, the intelligent linking of data, the integrity of the different issues of design and the design process, and the extensive use of images [Schuman et al 19881, these attributes incidentally define the word hypermedia. The LBL model, which uses hypermedia, seems to be the more promising direction for this type of research. However, there is still a need to establish a new model that integrates all aspects of the problem. The areas in which the present research departs from the LBL model can be listed as follows: it acknowledges the necessity of regarding the user as the center of the CAAD tool design, it develops a model that is based on one of the high level theories of human-computer interaction, and it develops a prototype tool that conforms to the model.

title	Requirements for Developing an Information System for Architecture
source	CAAD futures ‘87 [Conference Proceedings / ISBN 0-444-42916-6] Eindhoven (The Netherlands), 20-22 May 1987, pp. 149-170
summary	This paper discusses possibilities of developing new tools for architectural design. It argues that architects should meet the challenge of information technology and computer-based design techniques. One such attempt has been the first phase of the development of an architectural design information system (ADIS), also an architectural design decision support system. The system should benefit from the developments of the artificial intelligence to enable the architect to have access to information required to carry out design work. In other words: the system functions as a huge on-line electronic library of architecture, containing up-to-date architectural design information, literature, documents, etc. At the same time, the system offers necessary design aids such as computer programs for design process, drawing programs, evaluation programs, cost calculation programs, etc. The system also provides data communication between the architect and members of the design coalition team. This is found to be of vital importance in the architectural design process, because it can enable the architect to fit in changes, brought about in the project by different parties. Furthermore, they will be able, to oversee promptly the consequences of changes or decisions in a comprehensive manner. The system will offer advantages over the more commonly applied microcomputer based CAAD and IGDM (integrated graphics database management) systems, or even larger systems available to an architect. Computer programs as well as hardware change rapidly and become obsolete. Therefore, unrelenting investment pressure to up-date both software and hardware exists. The financial burden of this is heavy, in particular for smaller architectural practices (for instance an architect working for himself or herself and usually with few or no permanent staff). ADIS, as an on-line architectural design aid, is constantly up-dated by its own organisation. This task will be co-ordinated by the ADIS data- base administrator (DBA). The processing possibilities of the system are faster, therefore more complex processing tasks can be handled. Complicated large graphic data files, can be easily retrieved and manipulated by ADIS, a large system. In addition, the cost of an on-line system will be much less than any other system. The system is based on one model of the architectural design process, but will eventually contain a variety of design models, as it develops. The development of the system will be an evolutionary process, making use of its users' feed-back system. ADIS is seen as a step towards full automation of architectural design practices. Apart from being an architectural design support system, ADIS will assist the architect in his/her administrative and organisational activities.

title	The knowledge based representation and manipulation of geometry
source	Carnegie Mellon University
summary	An approach to the integration of geometric information in knowledge based systems is described as an architecture for geometric reasoning. The general requirements for this integration arise from the need for rich geometry representations in engineering domains and the conflicting demands of current geometric modelling and knowledge based systems. Four concepts are used as a basis: (1) Classes of spatial sets, which act by inheritance as a means for incremental definition by specialization, (2) Features, which denote evaluated portions of a geometric model, (3) Abstractions, which provide partial representations of geometric objects, and (4) Constraints through which spatial relationships are expressed. These four concepts combine in a synergistic manner to define the complete architecture. A prototype implementation of the architecture, built using object oriented programming techniques and a boundary based solid modeller, has been achieved and demonstrated through examples in the domains of robot task planning and automotive parts design.

title	Shape Models in Computer-Integrated Manufacture : A Review
source	18 p. Winchester: IBM UK Scientific Center, IBM United Kingdom Laboratories Limited, January, 1988. IBM UKSC Report 183. includes bibliography
summary	Existing computer-aided manufacturing systems are based on models of shape tailored to a particular process. Computer- integrated manufacture involves many different processes, and hence requires more complete models of components or assemblies. This can be provided by solid modelling techniques extended to include extra data related to manufacture such as form features and tolerances. These developments are being applied to many manufacturing processes, from casting to assembly, but profound questions remain concerning both the structure and the use of shape models in manufacture

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

title	Computer Vision: A First Course
source	Blackwell Scientific Publications
summary	Computer vision is a new discipline recently developed from image processing, which is able to take raw images, and, after suitable processing, derive information from them automatically. Computer vision applications are legion in the areas of automated manufacture and robotics, where it may be addressed to such problems as resolving motion in images, and 3-D analysis. This book is a much-needed introduction to the subject for senior undergraduates and graduates. It covers the necessary mathematical techniques at a level suitable for the mathematical literate who has not encountered any image processing before, and proceeds to an examination of some pure vision applications. There is a discussion of human perception and how it relates to machine perception, and there are examples throughout the text, with exercises at the end of each chapter.

title	Elements for Spatial Reasoning in Construction
source	Robotics in Construction, International Symposium (5th : 1988 : Tokyo, Japan). pp. 105- 113 : ill. includes bibliography
summary	According to AI techniques, spatial reasoning is seen in construction as generation and solving of goals involving a spatial representation model of buildings defining a rich taxonomy of parts and elements, and spatial relationships between these parts and elements. The authors define spatial representation model and spatial relationship from previous experiments in architect knowledge representation and automated surveying. The aim is to enable very abstract and short descriptions of building component assemblies, from designers at drawing-boards or from workers on sites, which can be processed and transformed in basic geometrical properties

title	A Model for Knowledge-Based Design Optimization [PhD dissertation]
source	Dept. of Architectural Science, University of Sydney
summary	Unpublished. CADLINE has abstract only. This dissertation is concerned with developments in design decision methodologies applied to computer-aided design. The major aim of this research was to design and develop a knowledge-based computer-aided optimization system that has the ability to emulate some of the human performances in design decision processes. The issues and problems involved in developing a knowledge-based system for design optimization are addressed. A knowledge-based methodology to aid design optimization formulation is investigated. The major issues considered include representation of design description, the variety of knowledge required for the formulation process, recognizing optimization formulations, and selection of appropriate algorithms. It is demonstrated that the knowledge-based control of numerical processes leads to efficient and improved decisions in design. In developing knowledge-based systems for computer-aided decision applications an effective human-machine interface is essential. A model for knowledge-based graphical interfaces is proposed. This model incorporates knowledge for graphics interpretation, extraction of features of graphics objects and identification of prototypical objects. An experimental system developed in Prolog and C is demonstrated in the domain of structural design. The system shows one way of combining knowledge-based systems technology with computer graphics and indicates how knowledge-based interfaces improve the system's interactive capabilities. Finally, the system, OPTIMA, is presented. The system is designed as an integrated knowledge-based decision system using frames, rule bases, menu inputs, algebraic computation and optimization algorithms. The system has been written in LISP, Prolog and C and implemented on SUN Microsystems workstations. The performance of the system is demonstrated using two example problems from the domains of structural and architectural design respectively. The knowledge-based approach to design optimization is shown to be considerably easier and more efficient than those using conventional programs.

title	Integrated Design and Building System for the Provision of Customized Housing: the Case of Post-Earthquake Haiti
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 247-264.
summary	The paper proposes integrated design and building systems for the provision of sustainable customized housing. It advances previous work by applying a methodology to generate these systems from vernacular precedents. The methodology is based on the use of shape grammars to derive and encode a contemporary system from the precedents. The combined set of rules can be applied to generate housing solutions tailored to specific user and site contexts. The provision of housing to shelter the population affected by the 2010 Haiti earthquake illustrates the application of the methodology. A computer implementation is currently under development in C# using the BIM platform provided by Revit. The world experiences a sharp increase in population and a strong urbanization process. These phenomena call for the development of effective means to solve the resulting housing deficit. The response of the informal sector to the problem, which relies mainly on handcrafted processes, has resulted in an increase of urban slums in many of the big cities, which lack sanitary and spatial conditions. The formal sector has produced monotonous environments based on the idea of mass production that one size fits all, which fails to meet individual and cultural needs. We propose an alternative approach in which mass customization is used to produce planed environments that possess qualities found in historical settlements. Mass customization, a new paradigm emerging due to the technological developments of the last decades, combines the economy of scale of mass production and the aesthetics and functional qualities of customization. Mass customization of housing is defined as the provision of houses that respond to the context in which they are built. The conceptual model for the mass customization of housing used departs from the idea of a housing type, which is the combined result of three systems (Habraken, 1988) -- spatial, building system, and stylistic -- and it includes a design system, a production system, and a computer system (Duarte, 2001). In previous work, this conceptual model was tested by developing a computer system for existing design and building systems (Benr__s and Duarte, 2009). The current work advances it by developing new and original design, building, and computer systems for a particular context. The urgent need to build fast in the aftermath of catastrophes quite often overrides any cultural concerns. As a result, the shelters provided in such circumstances are indistinct and impersonal. However, taking individual and cultural aspects into account might lead to a better identification of the population with their new environment, thereby minimizing the rupture caused in their lives. As the methodology to develop new housing systems is based on the idea of architectural precedents, choosing existing vernacular housing as a precedent permits the incorporation of cultural aspects and facilitates an identification of people with the new housing. In the Haiti case study, we chose as a precedent a housetype called ‚Äúgingerbread houses‚Äù, which includes a wide range of houses from wealthy to very humble ones. Although the proposed design system was inspired by these houses, it was decided to adopt a contemporary take. The methodology to devise the new type was based on two ideas: precedents and transformations in design. In architecture, the use of precedents provides designers with typical solutions for particular problems and it constitutes a departing point for a new design. In our case, the precedent is an existing housetype. It has been shown (Duarte, 2001) that a particular housetype can be encoded by a shape grammar (Stiny, 1980) forming a design system. Studies in shape grammars have shown that the evolution of one style into another can be described as the transformation of one shape grammar into another (Knight, 1994). The used methodology departs takes off from these ideas and it comprises the following steps (Duarte, 2008): (1) Selection of precedents, (2) Derivation of an archetype; (3) Listing of rules; (4) Derivation of designs; (5) Cataloguing of solutions; (6) Derivation of tailored solution.

title	Logic Models of Design
source	Pitman, London
summary	This monograph places design in a theoretical context which applies developments in knowledge-based systems, logic programming and planning to design. It addresses two important design issues: the interpretation of designs, which concerns the discovery of implicit design attributes, a key activity in design evaluation that can be modelled by deductive inference in logic programming; and the process of generation, whereby a design description is produced which exhibits these implicit design attributes. Implicit attributes can be seen as analogous to the semantic content of natural language utterances. The work presented here is mainly concerned with design generation, and an operational model of design is investigated in which operations on processes are treated in a similar way to operations on form. It is argued that there are advantages in representing control knowledge as rules in a design system, and that logic is an effective medium for this purpose. This is demonstrated by means of programs developed in Prolog and C using the example of spatial layout in buildings. Primarily, this book is directed at those in artificial intelligence (AI) involved in logic programming, planning and expert systems. However, since AI techniques are finding widespread application in industry, the use of an architectural design example makes this work relevant to architects, designers, engineers and developers of intelligent architectural design software.

title	A Hierarchical Boundary Model for Solid Object Representation
source	ACM Transactions on Graphics. January, 1988. vol. 7: pp. 42-60 : ill. includes bibliography
summary	A new hierarchical model for solid object representation is described. This model, called a Hierarchical Face Adjacency Hypergraph (HFAH), is based on a relational description of the object boundary, called a Face Adjacency Hypergraph (FAH), which considers faces as the primary topological entities defining the object boundary. The HFAH consists of a hierarchy of FAHs describing the decomposition of the boundary of an object into form features. In this paper the HFAH is described together with its internal encoding structure. Two basic transformations, called refinement and abstraction, are defined on the hierarchical model; these allow effective and efficient modifications of the hierarchical boundary model

source	Artificial Intelligence in Engineering: Design. editor. John J. Gero. Elsevier (Computational Mechanics Publications), 1988. PP. 445-464 : ill. includes bibliography
summary	The paper describes an attempt to increase the intelligence of a CAD system by adding capabilities (1) to systematically enumerate alternative solutions to a design problem, and (2) to take, at the same time, a broad spectrum of criteria or concerns into account. These capabilities are intended to complement the designer's abilities and performance. In connection with such attempts, fundamental problems arise when the objects to be designed have shape and are located in space. These problems are identified, and an approach to solve them is outlined. This approach is currently being tested over a range of domains all of which deal with the design of layouts of rectangles subject to constraints and criteria. The search for alternatives takes place in a state space with properties that make it possible to systematically explore and evaluate the power of various search strategies or planning paradigms. The state space is established through a domain-independent generator, while the evaluation of points in that space is carried out by a domain-dependent tester built up through a process of knowledge acquisition familiar from work with expert systems

summary	Discovery and innovation, which have traditionally involved thinking visually and producing images, increasingly benefit from labor-saving devices like GIS and CAD. As new visualization technologies are implemented, it is particularly important to understand the human faculties which use pictures as tools in thinking. Science and engineering define problems, explain processes, and design solutions through observation, imagination and logic. This conceptual thought relies on a cognitive `database' of sensed verbal and non-verbal information, which is retained, managed, and updated within the short and long-term human memories. Research suggests that the individual must actively manipulate a phenomenon under study and its representations to enhance and maintain this database, and to produce abstractions and generalizations. Graphics are particularly important in this process of discovering correlations, contradictions and connections, and subsequent communication to others. Graphics offer high information density, simultaneity, variable detail and the capacity for showing multivariate relations. A `gestalt' property leads to the discovery of new relationships since the graphic whole always exceeds the sum of its parts. A cycle occurs in which the individual interacts with the phenomenon and produces explicit knowledge in the form of graphics and text, testing and refining each against knowledge and abstractions held in the mind

title	A new paradigm for life-cycle management of kit-of-parts building systems
source	UNIVERSITY OF MICHIGAN , PhD
summary	The research described in this dissertation brings together various technologies in manufacturing and information management and suggests a new paradigm for the design, manufacture, and lifetime use of artifacts using kit-of-parts systems and rule-based assembly. The questions are asked: If architects, designers, and users were given direct online connection to real-time design information sources and fabrication processes, and have the ability to monitor and control the current state of designed objects throughout the objects' lifetime, how would the entire life-cycle of a product be affected, and how would design processes change? During the course of the research described in this dissertation, a series of simulations and experiments were conducted which produced a computer-based simulated design, manufacture, and use environment wherein these questions could begin to be answered. A kit-of-parts model building system was devised which could be used to design model buildings in virtual form by downloading virtual representations of the components from the Internet and assembling them into a desired form. The virtual model building could then be used to order the manufacture of real components online, and remotely controlled robots used to assemble the actual building on the site. Through the use of special hardware manufactured into the components, real-time remote monitoring and control of the current state of the finished model building was affected during the building's lifetime. The research establishes the feasibility of an online life-cycle environment where a virtual representation of an artifact is created and used to both manufacture a real-world counterpart and also monitor and control the current state of the real-world object. The state-of-the-art of pertinent technologies were explored through literature searches and experiments. Data representation, rule-based design techniques, robotics, and digital control were studied, and a series of design principles established which lend themselves toward a life-cycle management paradigm. Several case studies are cited which show how the design principles and life-cycle management environment can be applied to real buildings and other artifacts such as vehicles and marine structures. Ideas for expanded research on the life-cycle management paradigm are cited.

title	A Preliminary Model of Creativity in Digital Development of Architecture

summary	Research into the various forms and processes of creativity has been a topic of great interest in the design field for many years. Part of the view is personality, and part of the answer is behavioural. Creativity is also explained through the identity of social values and the whole creative process. This paper proposes to use the interacting creativity model of Csikszentmihalyi as the basic structure, to establish the major criteria of testing creativity in the digital era. This paper demonstrates two facts: first, it confirms that creativity in architecture is truly valuable in the digital age; second, it proves that in the digital era, individuals, cultures and societies are all under the impact of digital technologies, a fact which transforms the model of interacting creativity proposed by Csikszentmihalyi in 1988 into a new model of digital interacting creativity.

title	A Conceptual Framework for Computing in Architectural Design
source	Pennsylvania State University
summary	A brief historical overview of architectural design reveals that there has been a slow development in the conceptualization of the scope of architectural design. Advancing our understanding of the architectural design process reveals new directions for computing in architectural design. This study proposes a conceptual framework for an integrated computing environment. Design disciplines have embarked on a rigorous search for theoretical perspectives and methods that encompass a comprehensive view of architecture. Architectural design has been seen as a sequential process similar to that of industrial design. Attempts to formalize this process based on industrial design methods solved only a fraction of the overall integration problem. The resultant models are inadequate to deal with the complexity of architectural design. Emerging social problem-solving paradigms seek to construct a cognitive psychology of problem solving and have a direct relevance to architectural design. These problem-solving activities include structured, semi-structured, and ill-defined problems, which are included to varying degrees in each problem situation across a continuum of difficulty. Problem solving in architectural design involves the determination of certain objectives and also whether or not it is possible to accomplish them. Developments in computing in architecture have paralleled developments in architectural methodologies. The application of computing in architectural design has predominantly focused only on sequential process, optimum solutions, and quantifiable tasks of the design process. Qualitative, generative, tasks of architectural design were dealt with through the introduction of paradigms from linguistics and knowledge-based systems borrowed from engineering applications. Although the application of such paradigms resulted in some success, this reductionist approach to computing in architecture fragmented its integration into the design process. What is required, therefore, is a unified approach to computing in architecture based on a holistic view of the architectural design process. The model proposed in this study provides such a conceptual framework. This model shifts the focus from product to process and views the design problem as a goal-oriented problem-solving activity that allows a design team to identify strategies and methodologies in the quest for design solutions.

summary	The architectural design process has more than one participant. Each participant has his own way of approaching the information embedded in a design. In the future the CAAD systems of these participants must be able to communicate and exchange information. For a communication of this kind there must be a common ground, a frame of reference, in which these different points of view can be expressed. This frame of reference or model must support participants accessing the same information with different objectives and for different purposes. We shall propose such a model based on research results obtained by the analysis of architectural knowledge and designs. The model incorporates certain aspects drawn from AI.

title	Introducing CAD to a Big Corporation
source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 497-512
summary	The report presents the ongoing activity of introducing CAD to the entire range of facilities planning and management of the Frankfurt Airport Corporation. It addresses issues of organizing the shift from conventional to computer supported planning and facilities management,- the problems of training professionals with various background in the use of new tools; aspects of data validity; regulation of data exchange; and customization of software to the needs of special tasks within the corporation. The report is based on about four years of project runtime. The preparation of the project started in fall 1988. The project proper started in June 1989. It is entering its last year. Up to now about 120 persons have been trained to use CAD.
