title On the Conceptual Feasibility of a CAAD-CAAI Integrated Decision Support System: A Computer Aided Environment for Technical Decision Making in Architecture
source Delft University of Technology
summary This document addresses two questions: What are the ultimate means of design support we can offer to the architect, and how can we devise them? We are not the first ones to address these questions, neither the first ones to point our finger in the direction of Decision Support Systems for such purposes. Nevertheless, we may be among those scholars that understanding 'Decision Support" in terms of "Learning Support", are willing to explore the implications that such an understanding assumes for the concept of Decision Support Systems. Our exploration in such regards has shown us that knowledge application and knowledge acquisition cycles describe a continuum, and that such cycles, encapsulated in our "Practice Based Learning" and "Continuing Professional Development" dynamics are present in both our instructional and professional environments. From such a perspective, our scope regarding feasible Decision Support Systems is not restricted to the use of CAAD instrumental resources, but expanded into a context of CAAD-CAAI integration. Throughout this document we conceive a system that blends CAAD and CAAI resources looking forward to the creation of a Support Environment that seeks to motivate a reflective attitude during design, in such a way, upgrade our capability for acquiring as well as applying knowledge in design. In instrumental terms, this document explains how mainstream CAAD developments in the field of "Intelligent Front End Technology" and CAAI developments in the field of "Knowledge-based Curricular Networks" can complement each other in the establishment of a Decision Support System of trans-environmental relevancy. As an application framework for the concept and instrumental base described above, this document presents an image of the kind of decision-making model that it will intend to support, the kind of task support model it will look forward to implement, and the kind of general instrumental layout it will require. On the basis of such an instrumental layout, the system that is hereby outlined can be regarded as a "CAAD-CAAI Integrated", "Intelligent", and "User-Oriented" Interface System.

title Computing And Manipulation In Design - A Pedagogical Experience Using Symmetry
source SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary The concept of symmetry has been usually restricted to bilateral symmetry, though in an extended sense it refers to any isometric transformation that maintains a certain shape invariant. Groups of operations such as translation, rotation, reflection and combinations of these originate patterns classified by modern mathematics as point groups, friezes and wallpapers (March and Steadman, 1974). This extended notion represents a tool for the recognition and reproduction of patterns, a primal aspect of the perception, comprehension and description of everything that we see. Another aspect of this process is the perception of shapes, primary and emergent. Primary shapes are the ones explicitly represented and emergent shapes are the ones implicit in the others (Gero and Yan, 1994). Some groups of shapes known as Semantic Shapes are especially meaningful in architecture, expressing visual features so as symmetry, rhythm, movement and balance. The extended understanding of the concept of symmetry might improve the development of cognitive abilities concerning the creation, recognition and meaning of forms and shapes, aspects of visual reasoning involved in the design process. This paper discusses the development of a pedagogical experience concerned with the application of the concept of symmetry in the creative generation of forms using computational tools and manipulation. The experience has been carried out since 1995 with 3rd year architectural design students. For the exploration of compositions based on symmetry operations with computational support we followed a method developed by Celani (2003) comprising the automatic generation and update of symmetry patterns using AutoCAD. The exercises with computational support were combined with other different exercises in each semester. The first approach combined the creation of two-dimensional patterns to their application and to their modeling into three-dimensions. The second approach combined the work with computational support with work with physical models and mirrors and the analysis of the created patterns. And the third approach combined the computational tasks with work with two-dimensional physical shapes and mirrors. The student’s work was analyzed under aspects such as Discretion/ Continuity –the creation of isolated groups of shapes or continuous overlapped patterns; Generation of Meta-Shapes –the emergence of new shapes from the geometrical relation between the generative shape and the structure of the symmetrical arrangement; Modes of Representation –the visual aspects of the generative shape such as color and shading; Visual Reasoning –the derivation of 3D compositions from 2D patterns by their progressive analysis and recognition; Conscious Interaction –the simultaneous creation and analysis of symmetry compositions, whether with computational support or with physical shapes and mirrors. The combined work with computational support and with physical models and mirrors enhanced the students understanding on the extended concept of symmetry. The conscious creation and analysis of the patterns also stimulated the student’s understanding over the different semantic possibilities involved in the exploration of forms and shapes in two or three dimensions. The method allowed the development of both syntactic and semantic aspects of visual reasoning, enhancing the students’ visual repertoire. This constitutes an important strategy in the building of the cognitive abilities used in the architectural design process.

summary A general framework of a system that supports building engineering is presented. It accounts for a set of desirable features. Among them are (1) graphical man-machine interaction, (2) high interactivity to facilitate the acquisition of the huge amount of knowledge necessary to support design, (3) incremental knowledge acquisition as the basis for incrementally increasing system support, and (4) adaptability to the tasks which are tackled, the distinctive features of the domain, and user preferences. This paper provides the underlying assumptions and basic approaches of the modules constituting this framework and sketches the current implementation.

title Galathea: A Case-Based Planning Tool for Knowledge Navigation in the Architectural Design Process

summary We report on an on-going Ph.D. research aimed at the analysis of the nature of process knowledge in architectural design and the development of a conceptual model for a case-based navigation tool for its support. We describe architectural design from a process viewpoint and assume it as a form of intentional planning, leading from an initial state configuration toward a desired situation, by means of an incremental specification of goals, constraints and involved variables. We consider the very essence of design and of the specific professional skill characterising designers as the continual recursive transformation of the initial solution model, in order to map the desired state onto the enacted one and the capability to govern a number of continually changing variables in this direction. On the basis of this general concept of the design process, we describe the model of Galathea, a case-based planning tool, aimed at progressively representing the enlarging space of acquired knowledge, and at supporting the designer´s central role in the management of the design process.

title Applying Formal Methods to Multimedia Design Aid
doi https://doi.org/10.52842/conf.ecaade.1995.283
source Multimedia and Architectural Disciplines [Proceedings of the 13th European Conference on Education in Computer Aided Architectural Design in Europe / ISBN 0-9523687-1-4] Palermo (Italy) 16-18 November 1995, pp. 283-296
summary In the last decade we assisted at an evolution of computer aided design systems from drafting, calculation and simulation utilities toward systems able to support the conceptual phase of the design process. Systems supporting conceptual design use knowledge about the design domain and assume a will defined model of the design activity. Their computational framework is usually built by means of a set of representational schemata which lack a formal semantics. This aspect causes a limitation on the applicability of their computational framework to different domains. In this paper we propose a formal knowledge representation language, that has been defined in order to represent the structural relationships of domain knowledge. On the basis of language structure we propose a number of inferences tailored to case-based conceptual design aiding. Finally we apply the representational framework to the implementation of a computational architecture for conceptual design aiding that integrates multimedia representation of design cases with symbolic information processing. The architecture combines a knowledge representation server and a multimedia server. The knowledge representation server processes both domain knowledge and design experiences according to the Case Based Reasoning paradigm. The multimedia server produces the required case representation.

title AN EVOLUTIONARY ARCHITECTURE
source London: Architectural Association
summary In "An Evolutionary Architecture", John Frazer presents an overview of his work for the past 30 years. Attempting to develop a theoretical basis for architecture using analogies with nature's processes of evolution and morphogenesis. Frazer's vision of the future of architecture is to construct organic buildings. Thermodynamically open systems which are more environmentally aware and sustainable physically, sociologically and economically. The range of topics which Frazer discusses is a good illustration of the breadth and depth of the evolutionary design problem. Environmental Modelling One of the first topics dealt with is the importance of environmental modelling within the design process. Frazer shows how environmental modelling is often misused or misinterpreted by architects with particular reference to solar modelling. From the discussion given it would seem that simplifications of the environmental models is the prime culprit resulting in misinterpretation and misuse. The simplifications are understandable given the amount of information needed for accurate modelling. By simplifying the model of the environmental conditions the architect is able to make informed judgments within reasonable amounts of time and effort. Unfortunately the simplications result in errors which compound and cause the resulting structures to fall short of their anticipated performance. Frazer obviously believes that the computer can be a great aid in the harnessing of environmental modelling data, providing that the same simplifying assumptions are not made and that better models and interfaces are possible. Physical Modelling Physical modelling has played an important role in Frazer's research. Leading to the construction of several novel machine readable interactive models, ranging from lego-like building blocks to beermat cellular automata and wall partitioning systems. Ultimately this line of research has led to the Universal Constructor and the Universal Interactor. The Universal Constructor The Universal Constructor features on the cover of the book. It consists of a base plug-board, called the "landscape", on top of which "smart" blocks, or cells, can be stacked vertically. The cells are individually identified and can communicate with neighbours above and below. Cells communicate with users through a bank of LEDs displaying the current state of the cell. The whole structure is machine readable and so can be interpreted by a computer. The computer can interpret the states of the cells as either colour or geometrical transformations allowing a wide range of possible interpretations. The user interacts with the computer display through direct manipulation of the cells. The computer can communicate and even direct the actions of the user through feedback with the cells to display various states. The direct manipulation of the cells encourages experimentation by the user and demonstrates basic concepts of the system. The Universal Interactor The Universal Interactor is a whole series of experimental projects investigating novel input and output devices. All of the devices speak a common binary language and so can communicate through a mediating central hub. The result is that input, from say a body-suit, can be used to drive the out of a sound system or vice versa. The Universal Interactor opens up many possibilities for expression when using a CAD system that may at first seem very strange.However, some of these feedback systems may prove superior in the hands of skilled technicians than more standard devices. Imagine how a musician might be able to devise structures by playing melodies which express the character. Of course the interpretation of input in this form poses a difficult problem which will take a great deal of research to achieve. The Universal Interactor has been used to provide environmental feedback to affect the development of evolving genetic codes. The feedback given by the Universal Interactor has been used to guide selection of individuals from a population. Adaptive Computing Frazer completes his introduction to the range of tools used in his research by giving a brief tour of adaptive computing techniques. Covering topics including cellular automata, genetic algorithms, classifier systems and artificial evolution. Cellular Automata As previously mentioned Frazer has done some work using cellular automata in both physical and simulated environments. Frazer discusses how surprisingly complex behaviour can result from the simple local rules executed by cellular automata. Cellular automata are also capable of computation, in fact able to perform any computation possible by a finite state machine. Note that this does not mean that cellular automata are capable of any general computation as this would require the construction of a Turing machine which is beyond the capabilities of a finite state machine. Genetic Algorithms Genetic algorithms were first presented by Holland and since have become a important tool for many researchers in various areas.Originally developed for problem-solving and optimization problems with clearly stated criteria and goals. Frazer fails to mention one of the most important differences between genetic algorithms and other adaptive problem-solving techniques, ie. neural networks. Genetic algorithms have the advantage that criteria can be clearly stated and controlled within the fitness function. The learning by example which neural networks rely upon does not afford this level of control over what is to be learned. Classifier Systems Holland went on to develop genetic algorithms into classifier systems. Classifier systems are more focussed upon the problem of learning appropriate responses to stimuli, than searching for solutions to problems. Classifier systems receive information from the environment and respond according to rules, or classifiers. Successful classifiers are rewarded, creating a reinforcement learning environment. Obviously, the mapping between classifier systems and the cybernetic view of organisms sensing, processing and responding to environmental stimuli is strong. It would seem that a central process similar to a classifier system would be appropriate at the core of an organic building. Learning appropriate responses to environmental conditions over time. Artificial Evolution Artificial evolution traces it's roots back to the Biomorph program which was described by Dawkins in his book "The Blind Watchmaker". Essentially, artificial evolution requires that a user supplements the standard fitness function in genetic algorithms to guide evolution. The user may provide selection pressures which are unquantifiable in a stated problem and thus provide a means for dealing ill-defined criteria. Frazer notes that solving problems with ill-defined criteria using artificial evolution seriously limits the scope of problems that can be tackled. The reliance upon user interaction in artificial evolution reduces the practical size of populations and the duration of evolutionary runs. Coding Schemes Frazer goes on to discuss the encoding of architectural designs and their subsequent evolution. Introducing two major systems, the Reptile system and the Universal State Space Modeller. Blueprint vs. Recipe Frazer points out the inadequacies of using standard "blueprint" design techniques in developing organic structures. Using a "recipe" to describe the process of constructing a building is presented as an alternative. Recipes for construction are discussed with reference to the analogous process description given by DNA to construct an organism. The Reptile System The Reptile System is an ingenious construction set capable of producing a wide range of structures using just two simple components. Frazer saw the advantages of this system for rule-based and evolutionary systems in the compactness of structure descriptions. Compactness was essential for the early computational work when computer memory and storage space was scarce. However, compact representations such as those described form very rugged fitness landscapes which are not well suited to evolutionary search techniques. Structures are created from an initial "seed" or minimal construction, for example a compact spherical structure. The seed is then manipulated using a series of processes or transformations, for example stretching, shearing or bending. The structure would grow according to the transformations applied to it. Obviously, the transformations could be a predetermined sequence of actions which would always yield the same final structure given the same initial seed. Alternatively, the series of transformations applied could be environmentally sensitive resulting in forms which were also sensitive to their location. The idea of taking a geometrical form as a seed and transforming it using a series of processes to create complex structures is similar in many ways to the early work of Latham creating large morphological charts. Latham went on to develop his ideas into the "Mutator" system which he used to create organic artworks. Generalising the Reptile System Frazer has proposed a generalised version of the Reptile System to tackle more realistic building problems. Generating the seed or minimal configuration from design requirements automatically. From this starting point (or set of starting points) solutions could be evolved using artificial evolution. Quantifiable and specific aspects of the design brief define the formal criteria which are used as a standard fitness function. Non-quantifiable criteria, including aesthetic judgments, are evaluated by the user. The proposed system would be able to learn successful strategies for satisfying both formal and user criteria. In doing so the system would become a personalised tool of the designer. A personal assistant which would be able to anticipate aesthetic judgements and other criteria by employing previously successful strategies. Ultimately, this is a similar concept to Negroponte's "Architecture Machine" which he proposed would be computer system so personalised so as to be almost unusable by other people. The Universal State Space Modeller The Universal State Space Modeller is the basis of Frazer's current work. It is a system which can be used to model any structure, hence the universal claim in it's title. The datastructure underlying the modeller is a state space of scaleless logical points, called motes. Motes are arranged in a close-packing sphere arrangement, which makes each one equidistant from it's twelve neighbours. Any point can be broken down into a self-similar tetrahedral structure of logical points. Giving the state space a fractal nature which allows modelling at many different levels at once. Each mote can be thought of as analogous to a cell in a biological organism. Every mote carries a copy of the architectural genetic code in the same way that each cell within a organism carries a copy of it's DNA. The genetic code of a mote is stored as a sequence of binary "morons" which are grouped together into spatial configurations which are interpreted as the state of the mote. The developmental process begins with a seed. The seed develops through cellular duplication according to the rules of the genetic code. In the beginning the seed develops mainly in response to the internal genetic code, but as the development progresses the environment plays a greater role. Cells communicate by passing messages to their immediate twelve neighbours. However, it can send messages directed at remote cells, without knowledge of it's spatial relationship. During the development cells take on specialised functions, including environmental sensors or producers of raw materials. The resulting system is process driven, without presupposing the existence of a construction set to use. The datastructure can be interpreted in many ways to derive various phenotypes. The resulting structure is a by-product of the cellular activity during development and in response to the environment. As such the resulting structures have much in common with living organisms which are also the emergent result or by-product of local cellular activity. Primordial Architectural Soups To conclude, Frazer presents some of the most recent work done, evolving fundamental structures using limited raw materials, an initial seed and massive feedback. Frazer proposes to go further and do away with the need for initial seed and start with a primordial soup of basic architectural concepts. The research is attempting to evolve the starting conditions and evolutionary processes without any preconditions. Is there enough time to evolve a complex system from the basic building blocks which Frazer proposes? The computational complexity of the task being embarked upon is not discussed. There is an implicit assumption that the "superb tactics" of natural selection are enough to cut through the complexity of the task. However, Kauffman has shown how self-organisation plays a major role in the early development of replicating systems which we may call alive. Natural selection requires a solid basis upon which it can act. Is the primordial soup which Frazer proposes of the correct constitution to support self-organisation? Kauffman suggests that one of the most important attributes of a primordial soup to be capable of self-organisation is the need for a complex network of catalysts and the controlling mechanisms to stop the reactions from going supracritical. Can such a network be provided of primitive architectural concepts? What does it mean to have a catalyst in this domain? Conclusion Frazer shows some interesting work both in the areas of evolutionary design and self-organising systems. It is obvious from his work that he sympathizes with the opinions put forward by Kauffman that the order found in living organisms comes from both external evolutionary pressure and internal self-organisation. His final remarks underly this by paraphrasing the words of Kauffman, that life is always to found on the edge of chaos. By the "edge of chaos" Kauffman is referring to the area within the ordered regime of a system close to the "phase transition" to chaotic behaviour. Unfortunately, Frazer does not demonstrate that the systems he has presented have the necessary qualities to derive useful order at the edge of chaos. He does not demonstrate, as Kauffman does repeatedly, that there exists a "phase transition" between ordered and chaotic regimes of his systems. He also does not make any studies of the relationship of useful forms generated by his work to phase transition regions of his systems should they exist. If we are to find an organic architecture, in more than name alone, it is surely to reside close to the phase transition of the construction system of which is it built. Only there, if we are to believe Kauffman, are we to find useful order together with environmentally sensitive and thermodynamically open systems which can approach the utility of living organisms.

title A Dialogical Model for Participatory Design; A Computational Approach to Group Planning
source Delft University of Technology
summary In participatory design, design concepts are generated collectively through discussion, dialogical interactions, in which the interchange of normative and supporting factual descriptions builds a collective design discourse. The goal of this research is to develop a method for participatory design to support this collective, face-to-face design problem-solving, in order to increase the acceptability of the design product. Since the mid-1960s, there has been an important movement towards increasing the participation of citizens in determining their built environment. At first, the movement was associated with social-political ideologies and rhetoric. By the end of the 1970s, participatory design had become an accepted component of professional practice. The objectives of the movement became more pragmatically and more modestly focused on exchanging practical information, resolving conflicts, and supplementing design. Today, participatory design is in a new phase. Traditional participatory design methods are seen as insufficient to fulfill an increasing demand for dialogue. The point of departure of the study is the assumption that new information technologies can satisfy this demand. The method includes: (1) a group-reasoning model, (2) a dialogical system and (3) a framework for participation-based design guidelines. The group-reasoning model formulates the process of knowledge acquisition, the learning and sharing of belief systems, the generation of design alternatives and design evaluations--by which reasoning takes place dialogically. The dialogical system provides a clear description of how the information should be processed, what aspects should be paid attention to, what results can be anticipated, and when and how to control the process. The framework for participation-based design guidelines guides and structures the design process. It facilitates a reconstruction of the implicit cognitive structure which underlines dialogue and is generated through the discussion of a group.

summary The design problem has a multi-disciplinary nature and the design itself evolves as solutions are attempted by the designer. To support inter-disciplinary communication of design concepts and decisions, the integration of relevant CAAD tools is essential. Based upon a large set of design criteria and all corresponding knowledge, with the help of computer aided design tools, the result could be highly effective and novel. The integration of CAAD tools should be performed on the basis of generating better solutions by enabling designers to manipulate and appraise various solutions quickly and with a minimum of effort. The proposed system provides the foundations for a seamless and continuous working environment for architects and building engineers through a data modelling module, an integrated data management framework and various design tools. In the environment, stand-alone design tools can be plugged-in in order to access information stored in central databases. The suggested data modelling module helps integrated CAAD systems represent and exchange domain dependent design information at a semantic level, such as exchanging components and features of a building rather than graphical primitives. The suggested data management framework supports the straight-forward mechanisms for controlling the data representation through the inter-connected modules and design tools.

summary Designing is a complicated human behaviour and method, and is often treated as a mysterious "black box” operation in human mind. In the early period as for theory-studying of design thinking, the way of thinking that the researchers took were mostly descriptive discussions. Therefore, they lacked direct and empirical evidence although those studies provided significant exploration of design thinking (Wang, 1995). In recent years as for the study of cognitive science, they have tried to make design "glass box”. That is to try to make the thinking processes embedded in designers publicized. That is also to externalize the design procedure which provided the design studies another theoretical basis of more accurate and deeply researched procedure (Jones, 1992). Hence the studying of design thinking has become more important and the method of designing has also progressed a lot. For example, the classification of the nature of design problem such as ill-defined and well-defined (Newell, Shaw, and Simon, 1967), and different theoretical procedure modes for different disciplines, such as viewing architectural models as conjecture-analysis models and viewing engineering models as analysis-synthesis (Cross, 1991).

summary The villas of Le Corbusier from his Purist Corpus (1923-1929) are appropriate for reconstruction using computational tools for how their inherent logic is revealed by this process. Conceived but never built, the following seven design examples are inferred from incomplete and fragmentary original documentation and rebuilt as three-dimensional computer models. The analytic process of reconstruction depends upon available descriptive information, but more significant is the assumption of a design methodology based in geometry and elemental volumes. Understanding the basis of this method and its rules begins the systematic geometric reconstruction of the villas. The record of this process and the role of the machine in representing the object and its cognitive aspects is supported by the syntactic organization of images.

summary "Space," which has long been an important concept in architecture (Bloomer & Moore, 1977; Mitchell, 1995, 1999), has attracted interest of researchers from various academic disciplines in recent years (Agnew, 1993; Benko & Strohmayer, 1996; Chang, 1999; Foucault, 1982; Gould, 1998). Researchers from disciplines such as anthropology, geography, sociology, philosophy, and linguistics regard it as the basis of the discussion of various theories in social sciences and humanities (Chen, 1999). On the other hand, since the invention of Internet, Internet users have been experiencing a new and magic "world." According to the definitions in traditional architecture theories, "space" is generated whenever people define a finite void by some physical elements (Zevi, 1985). However, although Internet is a virtual, immense, invisible and intangible world, navigating in it, we can still sense the very presence of ourselves and others in a wonderland. This sense could be testified by our naming of Internet as Cyberspace -- an exotic kind of space. Therefore, as people nowadays rely more and more on the Internet in their daily life, and as more and more architectural scholars and designers begin to invest their efforts in the design of virtual places online (e.g., Maher, 1999; Li & Maher, 2000), we cannot help but ask whether there are indeed sensible spaces in Internet. And if yes, these spaces exist in terms of what forms and created by what ways?To join the current interdisciplinary discussion on the issue of space, and to obtain new definition as well as insightful understanding of "space", this study explores the spatial phenomena in Internet. We hope that our findings would ultimately be also useful for contemporary architectural designers and scholars in their designs in the real world.As a preliminary exploration, the main objective of this study is to discover the elements involved in the creation/construction of Internet spaces and to examine the relationship between human participants and Internet spaces. In addition, this study also attempts to investigate whether participants from different academic disciplines define or experience Internet spaces in different ways, and to find what spatial elements of Internet they emphasize the most.In order to achieve a more comprehensive understanding of the spatial phenomena in Internet and to overcome the subjectivity of the members of the research team, the research design of this study was divided into two stages. At the first stage, we conducted literature review to study existing theories of space (which are based on observations and investigations of the physical world). At the second stage of this study, we recruited 8 Internet regular users to approach this topic from different point of views, and to see whether people with different academic training would define and experience Internet spaces differently.The results of this study reveal that the relationship between human participants and Internet spaces is different from that between human participants and physical spaces. In the physical world, physical elements of space must be established first; it then begins to be regarded as a place after interaction between/among human participants or interaction between human participants and the physical environment. In contrast, in Internet, a sense of place is first created through human interactions (or activities), Internet participants then begin to sense the existence of a space. Therefore, it seems that, among the many spatial elements of Internet we found, "interaction/reciprocity" Ñ either between/among human participants or between human participants and the computer interface Ð seems to be the most crucial element.In addition, another interesting result of this study is that verbal (linguistic) elements could provoke a sense of space in a degree higher than 2D visual representation and no less than 3D visual simulations. Nevertheless, verbal and 3D visual elements seem to work in different ways in terms of cognitive behaviors: Verbal elements provoke visual imagery and other sensory perceptions by "imagining" and then excite personal experiences of space; visual elements, on the other hand, provoke and excite visual experiences of space directly by "mapping".Finally, it was found that participants with different academic training did experience and define space differently. For example, when experiencing and analyzing Internet spaces, architecture designers, the creators of the physical world, emphasize the design of circulation and orientation, while participants with linguistics training focus more on subtle language usage. Visual designers tend to analyze the graphical elements of virtual spaces based on traditional painting theories; industrial designers, on the other hand, tend to treat these spaces as industrial products, emphasizing concept of user-center and the control of the computer interface.The findings of this study seem to add new information to our understanding of virtual space. It would be interesting for future studies to investigate how this information influences architectural designers in their real-world practices in this digital age. In addition, to obtain a fuller picture of Internet space, further research is needed to study the same issue by examining more Internet participants who have no formal linguistics and graphical training.

source Automation in Construction 4 (2) (1995) pp. 101-110
summary Identifying and establishing a basic structure for knowledge representation is one of the keys to successful design of knowledge-based computer systems. In Building Design and Construction, this initial knowledge structure can be achieved by utilizing a query driven approach to software engineering. As (user) queries reflect the user's demand for in/output, it is natural to link the overall user dialogue with key elements in the knowledge base direct connections between user screen and objects in the knowledge base support prototyping and testing the application during development. However, the price for pursuing this approach in its pure form can be high, as needs for later maintenance and augmentation of the system can be very hard to fulfill. To overcome these problems, a strict user interlace, software separation strategy must be. introduced at early stages of software design. and implemented as a global control module as independent of the knowledge processing as possible.

title Patriarch: A Hypermedia Environment for the Support of Architectural Design
doi https://doi.org/10.52842/conf.ecaade.1995.187
source Multimedia and Architectural Disciplines [Proceedings of the 13th European Conference on Education in Computer Aided Architectural Design in Europe / ISBN 0-9523687-1-4] Palermo (Italy) 16-18 November 1995, pp. 187-198
summary This paper reports on current research in the field of architectural design and knowledge- based systems, through the conception and implementation of two software tools operating as a part of an integrated hypermedia environment denominated PatriArch. Main concern of this set of tools operating in PatriArch is the support of design since the very beginning, in that phase of not yet correctly explored or interpretated constraints and of scarcely specified goals, in which an initial solution model - provisionally composed of fragments of supposed fitting ideas - for the design theme has to take place. The creative activity of the designer is assumed as an 'intentional planning activity' that represents the acquired level of knowledge of the network of connections defining the nature, function, shape in the space etc. of the increasingly integrated solution-model: the final design will be an evolution of this - and other competitive and concurrent - models. PatriArch is meant to be the environment containing and allowing the representation of this evolution through its ability of linking the fragments of designers' knowledge, supported by an integrated relational data base: Sysinfo. These works were conceived inside an educational software development program for architecture students.

title DOM: An Active Assistance System for Architectural and Engineering Design
source Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 153-162
summary This article delineates an active design assistance system for conceptual design, called DOM which is the abbreviation for Domain Ontology Modelling. The intention of our work is to endorse the role of modelling a common and shared platform of design knowledge as well as to address the crucial task of representing design decisions and engineering judgements in order to evaluate design layouts and to support layout construction from scratch.The prerequisites and assumptions for an appropriate role of an active design assistance system are explained. The presented paper contains both a conceptual and a technical exploration of the DOM system.

title Faculties of Architecture
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary In order to be inscribed in the European Architect’s register the study program leading to the diploma ‘Architect’ has to meet the criteria of the EC Architect’s Directive (1985). The criteria are enumerated in 11 principles of Article 3 of the Directive. The Advisory Committee, established by the European Council got the task to examine such diplomas in the case some doubts are raised by other Member States. To carry out this task a matrix was designed, as an independent interpreting framework that mediates between the principles of Article 3 and the actual study program of a faculty. Such a tool was needed because of inconsistencies in the list of principles, differences between linguistic versions ofthe Directive, and quantification problems with time, devoted to the principles in the study programs. The core of the matrix, its headings, is a categorisation of the principles on a higher level of abstractionin the form of a taxonomy of domains and corresponding concepts. Filling in the matrix means that each study element of the study programs is analysed according to their content in terms of domains; thesummation of study time devoted to the various domains results in a so-called ‘profile of a faculty’. Judgement of that profile takes place by committee of peers. The domains of the taxonomy are intrinsically the same as the concepts and categories, needed for the description of an architectural design object: the faculties of architecture. This correspondence relates the taxonomy to the field of design theory and philosophy. The taxonomy is an application of Domain theory. This theory,developed by the authors since 1977, takes as a view that the architectural object only can be described fully as an integration of all types of domains. The theory supports the idea of a participatory andinterdisciplinary approach to design, which proved to be awarding both from a scientific and a social point of view. All types of domains have in common that they are measured in three dimensions: form, function and process, connecting the material aspects of the object with its social and proceduralaspects. In the taxonomy the function dimension is emphasised. It will be argued in the paper that the taxonomy is a categorisation following the pragmatistic philosophy of Charles Sanders Peirce. It will bedemonstrated as well that the taxonomy is easy to handle by giving examples of its application in various countries in the last 5 years. The taxonomy proved to be an adequate tool for judgement ofstudy programs and their subsequent improvement, as constituted by the faculties of a Faculty of Architecture. The matrix is described as the result of theoretical reflection and practical application of a matrix, already in use since 1995. The major improvement of the matrix is its direct connection with Peirce’s universal categories and the self-explanatory character of its structure. The connection with Peirce’s categories gave the matrix a more universal character, which enables application in other fieldswhere the term ‘architecture’ is used as a metaphor for artefacts.

title An integrated approach to CAD: modelling concepts in building design and construction
source Design Studies 16 (3) (1995) pp. 327-347
summary The ICON project is concerned with the creation of a generic information structure for the construction industry. A central feature of the information model is the use of object-oriented modelling techniques to allow information to be viewed from different 'perspectives' and at different levels of abstraction, according to the requirements of the user. This paper discusses the object modelling of concepts and information in the design area. Drawing on knowledge elicited from protocol analysis of the design activity, a series of interrelated object models has been developed, reflecting different perspectives and abstraction levels within the design domain. Three of these models (spatial design, physical design and structural design) are presented and their implications for the communication and sharing of information discussed.

title A Brief Note on Virtual Space
source CAD Space [Proceedings of the III International Conference Computer in Architectural Design] Bialystock 27-29 April 1995, pp. 83-92
summary In its efforts to represent space, and then create architecture on the basis of this representation, humanity has taken three major steps. STEP 1. Representation of space in the form of a drawing or model; representations compared to the mental vision and then redrawn or remodelled, until the vision takes the shape of a finished building. This technology of design" followed different conventions, depending on the epoch. In the Middle Ages the method of approximation by triangles was introduced. The Renaissance used Projection, Elevation and Cross-Section. In order to construct a building, a flat, abstract representation is used, supplemented by a model showing spatial relations and a verbal description, impossible to convey graphically. STEP 2. Methods as in Step 1, but, beginning in the 1970s, with the use of computers, which allows also for the gradual integration of these methods in one program. Theoretically speaking, all necessary data can be now recorded, visualized, animated, etc., on a PC class computer. The design-aid software is based on the method of creating a 3D model of the whole building, and then generating the rest (projections, cross-sections) from it. STEP 3. The above step have - brought us to near- perfection in photorealistic representation of space, which remains, however only a 2D abstraction from 3D space. The next step, which is now taking place before (and in?) our very eyes, is to use systems which bring us directly into 3D space.
