title	SHARED SPACE’ AND ‘PUBLIC SPACE’ DIALECTICS IN COLLABORATIVE ARCHITECTURAL DESIGN.
source	Proceedings of Collaborative Decision-Support Systems Focus Symposium, 30th July, 2002; under the auspices of InterSymp-2002, 14° International Conference on Systems Research, Informatics and Cybernetics, 2002, Baden-Baden, pg. 27-44.
summary	The present paper describes on-going research on Collaborative Design. The proposed model, the resulting system and its implementation refer mainly to architectural and building design in the modes and forms in which it is carried on in advanced design firms. The model may actually be used effectively also in other environments. The research simultaneously pursues an integrated model of the: a) structure of the networked architectural design process (operators, activities, phases and resources); b) required knowledge (distributed and functional to the operators and the process phases). The article focuses on the first aspect of the model: the relationship that exists among the various ‘actors’ in the design process (according to the STEP-ISO definition, Wix, 1997) during the various stages of its development (McKinney and Fischer, 1998). In Collaborative Design support systems this aspect touches on a number of different problems: database structure, homogeneity of the knowledge bases, the creation of knowledge bases (Galle, 1995), the representation of the IT datum (Carrara et al., 1994; Pohl and Myers, 1994; Papamichael et al., 1996; Rosenmann and Gero, 1996; Eastman et al., 1997; Eastman, 1998; Kim, et al., 1997; Kavakli, 2001). Decision-making support and the relationship between ‘private’ design space (involving the decisions of the individual design team) and the ‘shared’ design space (involving the decisions of all the design teams, Zang and Norman, 1994) are the specific topic of the present article. Decisions taken in the ‘private design space’ of the design team or ‘actor’ are closely related to the type of support that can be provided by a Collaborative Design system: automatic checks performed by activating procedures and methods, reporting of 'local' conflicts, methods and knowledge for the resolution of ‘local’ conflicts, creation of new IT objects/ building components, who the objects must refer to (the ‘owner’), 'situated' aspects (Gero and Reffat, 2001) of the IT objects/building components. Decisions taken in the ‘shared design space’ involve aspects that are typical of networked design and that are partially present in the ‘private’ design space. Cross-checking, reporting of ‘global’ conflicts to all those concerned, even those who are unaware they are concerned, methods for their resolution, the modification of data structure and interface according to the actors interacting with it and the design phase, the definition of a 'dominus' for every IT object (i.e. the decision-maker, according to the design phase and the creation of the object). All this is made possible both by the model for representing the building (Carrara and Fioravanti, 2001), and by the type of IT representation of the individual building components, using the methods and techniques of Knowledge Engineering through a structured set of Knowledge Bases, Inference Engines and Databases. The aim is to develop suitable tools for supporting integrated Process/Product design activity by means of a effective and innovative representation of building entities (technical components, constraints, methods) in order to manage and resolve conflicts generated during the design activity.

title	P3: Computational environment to support design collaboration
source	Automation in Construction 8 (1) (1998) pp. 37-48
summary	The work reported in this paper addresses the paradoxical state of the construction industry (also known as A/E/C, for Architecture, Engineering and Construction), where the design of highly integrated facilities is undertaken by severely fragmented teams, leading to diminished performance of both processes and products. The construction industry has been trying to overcome this problem by partitioning the design process hierarchically or temporally. While these methods are procedurally efficient, their piecemeal nature diminishes the overall performance of the project. Computational methods intended to facilitate collaboration in the construction industry have, so far, focused primarily on improving the flow of information among the participants. They have largely met their stated objective of improved communication, but have done little to improve joint decision-making, and therefore have not significantly improved the quality of the design project itself. We suggest that the main impediment to effective collaboration and joint decision-making in the A/E/C industry is the divergence of disciplinary `world-views', which are the product of educational and professional processes through which the individuals participating in the design process have been socialized into their respective disciplines. To maximize the performance of the overall project, these different world-views must be reconciled, possibly at the expense of individual goals. Such reconciliation can only be accomplished if the participants find the attainment of the overall goals of the project more compelling than their individual disciplinary goals. This will happen when the participants have become cognizant and appreciative of world-views other than their own, including the objectives and concerns of other participants. To achieve this state of knowledge, we propose to avail to the participants of the design team highly specific, contextualized information, reflecting each participant's valuation of the proposed design actions. P3 is a semantically-rich computational environment, which is intended to fulfill this mission. It consists of: (1) a shared representation of the evolving design project, connected (through the World Wide Web) to (2) individual experts and their discipline-specific knowledge repositories; and (3) a computational project manager makes the individual valuations visible to all the participants, and helps them deliberate and negotiate their respective positions for the purpose of improving the overall performance of the project. The paper discusses the theories on which the three components are founded, their function, and the principles of their implementation.

title	Computational decision support and the building delivery process: a necessary dialogue
source	Automation in Construction 7 (2-3) (1998) pp. 205-211
summary	The current critical discourse of computational design support systems (particularly building performance modeling tools) focuses more often than not on the `endogenous' system problems, that is deficiencies in user communication, absence of integration, and the `black-box' character of the underlying computational routines. As a result of this mostly valid criticism, work has been initiated in various quarters to improve modeling-based decision support environments. This paper argues that parallel efforts are needed to address other factors that go beyond the immediate technical realm of tool-making and involve matters pertaining to issues of building design and construction process at large. The building delivery process has traditionally been regarded as a discrete and sequential set of activities. This state of affairs is the result of a historical evolution driven by many factors, one of which might be the necessity to organize the activities for the purpose of establishing a professional fee structure that is commensurate with the scope of work and level of accountability or responsibility. However, within the context of rapidly changing building technologies, production processes, and knowledge transfer mechanisms, the existing procedural framework no longer seems capable of meeting the increasingly complex demands associated with the creation of the built environment. While the technical capabilities of decision support tools are expanding, they still fall short of challenging the very logic of the often nonintegrated processes they are designated to support. It may be understandable that, as compared to tools, processes tend to be more resilient to structural changes because of their inherent communicative nature, evolved over time through general acceptance and consensus. This paper argues, however, that careful study of the necessary conditions under which significant structural changes in the building delivery process would evolve, can effectively inform the developmental strategies in computational design support toward anticipation and encouragement of such changes.

title	Computer animation for architectural visualisation
source	University of Strathclyde
summary	This thesis critically reviews the state of architectural animation, and relates this specific field to the more general motion-based representations, particularly traditional film-making techniques. It identifies key elements from traditional filmmaking and shows how these elements can improve computer-based architectural animation. The process of identification of the key elements from traditional film-making starts with a critical survey of the use of motion-based representation in local architectural practices and an empirical analysis of several architectural-based documentary films and past and present computer animations. All of the key ideas are illustrated on video by comparing real shooting clips to digital sequences focusing on production and post-production works. Some of these were implemented in two live projects ( Ministry of Finance, Malaysia and Damansara Parade ) for architects to understand the real problems and potentials in each process. These sets of illustrations expand the architect ideas to make full use of the motion-based process to improve the skill of combining architectural information in a good animation. The overall production process becomes more efficient when the motion-based footage is edited using a non-linear editing platform as it enhances the professional appearance as well as vastly saving most of the production time. The thesis concludes with specific recommendations relative to the stage at which the animation is produced. This technology can be best utilised with the right skills (a gained from film-making) and an understanding of each stage that requires a different level of input and gives a certain impact to the viewers.

title	A Shape Compactness Measurement Indexing with Fuzzy Multicriteria Decision Making Approach
source	CAADRIA 2002 [Proceedings of the 7th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 983-2473-42-X] Cyberjaya (Malaysia) 18–20 April 2002, pp. 093-100
doi	https://doi.org/10.52842/conf.caadria.2002.093
summary	Compactness of a district or zone is determined by considering its appearance and the area of dispersal of the district (Altman, 1998) and it is used as a characteristic to describe shape (Shiode, 1998; Knight, 1997). However, existing compactness measurement used to assess district plans in redistricting applications are vague and imprecision although there are more than thirty over Euclidean or non-Euclidean measurement methods. Therefore, this paper presents an integrated shape compactness measurement indexing with a fuzzy multicriteria decision making approach (FMCDM) to enhance the measurement of shape compactness. An experiment is conducted in order to verify the practically of the proposed model to improve existing compactness measurement method.

title	A comparison of land valuation methods supported by GIS
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	The purpose of this work was to study three different strategies for the appraisal of urban land. The first, a theoretical strategy created by the authors of this study to reproduce the common conditions of Brazilian cities, uses increments and reductions in the value of a square meter of land according to each lot’s individual features. The second method, based on Multiple Regression techniques, is widely used for valuation purposes. Finally, the effectiveness of Artificial Neural Networks to deal with thiskind of problem is studied. A sample of 157 lots was collected from several neighbourhoods of a small Brazilian city for the case study. The lot features recorded were area, width, shape, distance to the downtown district of the city through the street network, existence of fences and paved sidewalks, and market price. Prediction errors have been estimated for each of the three methods in order to compare their results. Predicted and error values, added to Geographical Information Systems, may be used to build thematic maps and to check how each strategy applies to different areas of the city. The analyses of error values conducted in this study showed that Artificial Neural Networks presented the best performance as a land appraisal method for the case studied.

title	Prototypical Laboratory Design to Support Learning and Teaching
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	Collaboration between designers and scientists is an unusual combination to undertake the prototypical design of a teaching laboratory funded by Howard Hughes Medical Institute. The zoologists are developing a cooperative learning and interactive teaching pedagogy to make learningscience a process of critical inquiry and discovery. The industrial and interior designers are paying attention to the design issues of function and environmental support for teaching and doing the work required in a three-hour, hands-on beginning science learning space. Using both qualitative andquantitative research methods, the designers are able to determine a framework for making design decisions in prototypical beginning science environments. This framework is being developed as a guideline for designing similar environments at other institutions of higher learning. Videotape analysis precedes the research to uncover the underlying problems of the existing space and to formulate the questions for the research. Elements of a case study and an evaluative study integratewith the design process to form the basis of an intensive investigation of design issues for a beginning science teaching laboratory. Using two pretests as a baseline, the posttest data evaluates the success orfailure of the prototypical design. Both the pretests and the posttest evaluate the physical attributes of the old and new learning environment related to a beginning laboratory course in Zoology at Arizona State University.

title	Meshworks, Hierarchies and Interfaces
source	Virtual Dimension Ed. Beckmann, J., Princeton Architectural Press, NewYork
summary	The world of interface design is today undergoing dramatic changes which in their impact promise to rival those brought about by the use of the point-and-click graphical interfaces popularized by the Macintosh in the early 1980's. The new concepts and metaphors which are aiming to replace the familiar desk-top metaphor all revolve around the notion of semi-autonomous, semi-intelligent software agents. To be sure, different researchers and commercial companies have divergent conceptions of what these agents should be capable of, and how they should interact with computer users. But whether one aims to give these software creatures the ability to learn about the users habits, as in the non-commercial research performed at MIT autonomous agents group, or to endow them with the ability to perform transactions in the users name, as in the commercial products pioneered by General Magic, the basic thrust seems to be in the direction of giving software programs more autonomy in their decision-making capabilities.

title	Verification of Building Assemblage Compatability
source	Computerised Craftsmanship [eCAADe Conference Proceedings] Paris (France) 24-26 September 1998, pp. 234-238
doi	https://doi.org/10.52842/conf.ecaade.1998.234
summary	A computer program is being elaborated as an aid in designing assembled parts whose assembly presents high degrees of complexity. The newly created program, once incorporated in the CAD sector to increase its potential applications, will facilitate the analysis of reciprocal relationhips between pieces of the assemblage; this will enhance optimum decision-making in terms of geometric and functional characteristics with respect to the previously conceived assembly sequence. The program will automatically create images in three different ways: instantaneous images of assembly stages for each piece of the assembled part; exploded axonometric view of the whole structure with indications of necessary procedures for inserting or connecting the assembled part;sequenced procedures for connecting the assembled part. The different methods of visualization listed above will allow for project verification of the part by means of simultaneous visual analysis of the images and rapid updating should any changes in their properties arise. These types of visualization include simulations of piece by piece assemblage, which will facilitate an "optimal assemblage", meaning a set of components which are assembled in a specific sequence according to their "structural compatibility" and taking into consideration "particular assembly requirements".

title	Prototype of an Interactive Case Library for Architectural Design
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	Architects acquire an important part of their design knowledge from existing designs. Specific design projects from the past form an indispensable source of information and inspiration. Hence the idea todevelop a digital library of design cases that can be easily accessed during design. The paper describes a recently developed prototype of such a case library, intended to assist architecture students in the studio,yet with the potential of expansion into the office setting. When students enrol into a design project, they usually receive a reader with some relevant examples. At first sight, the digital case library only seems torepresent these examples into another medium, yet there are some important differences between both. Unlike the reader, the library has at its core an indexing-system which allows the easy retrieval of relevantinformation. By labelling projects with several features and making links between similar designs, the tool supports both directed search and browsing. A second difference is that the library is interactive. Studentsare not only able to consult interesting examples, but also to add other projects they consider relevant, to make links between them, to create extra indices etc. Finally, the tool allows to combine several media andto create links to external information sources.

title	The Role of Artifacts in Collaborative Design
source	CAADRIA ‘98 [Proceedings of The Third Conference on Computer Aided Architectural Design Research in Asia / ISBN 4-907662-009] Osaka (Japan) 22-24 April 1998, pp. 271-280
doi	https://doi.org/10.52842/conf.caadria.1998.271
summary	With the proliferation of digital technology, a new category of design artifacts, usually described with the term virtual, has emerged. Virtual artifacts have gained further prominence due to the advances made in collaboration software and networking technologies. These technologies have made it easier to communicate design intentions through the transfer and sharing of virtual rather than physical artifacts. This becomes particularly true in the case of long-distance or international collaborative efforts. This paper compares the two major categories of artifacts – the physical and the computer-based – and places them in relationship to an observed collaborative design process. In order to get at their specific roles in collaboration, two case studies were conducted in which designers in academic and professional settings were observed using a methodology which focused on participation in the everydayness of the designer as well as casual discussions, collection of artifacts, note-taking, and detailed descriptions of insightful events. The collected artifacts were then categorized according to the setting in which they were created and the setting in which they were intended to be used. These two attributes could have one of two values, private or public, which yield a matrix of four possible categories. It was observed that artifacts belonging in the same quadrant shared common qualities such as parsimony, completeness, and ambiguity. This paper finds that distinguishing between physical and virtual artifacts according to their material and imagined attributes is neither accurate nor useful. This research illustrates how virtual artifacts can obtain the qualities of their physical counterparts and vice versa. It also demonstrates how a new meta-artifact can emerge from the inclusion and unification of its material and imagined components. In conclusion, the paper calls for a seamless continuity in the representation and management of physical and virtual artifacts as a prerequisite to the success of: (1) computer-supported collaborative design processes, (2) academic instruction dealing with making and artifact building, and (3) executive policies in architectural practice addressing the management of architectural documents.

title	Making Models Architectural: Protean Representations to Fit Architects’ Minds
source	Digital Design Studios: Do Computers Make a Difference? [ACADIA Conference Proceedings / ISBN 1-880250-07-1] Québec City (Canada) October 22-25, 1998, pp. 354-365
doi	https://doi.org/10.52842/conf.acadia.1998.354
summary	A rich vocabulary has evolved for describing architecture. It serves not only as a means of communication, but also as an embodiment of concepts relating to form, space, structure, function, mood, and symbolism. We architects not only speak in terms of walls, rooms, roofs, arches, etc., we see in terms of them and think in terms of them, as well. Such concepts are integral to our ability to design. Typical CAD representations, however, are based on geometric/mathematical elements like points, lines, planes, and symbols. Even more experimental approaches like parametric shapes or procedural assemblies correspond poorly to architectural elements, and seldom lend themselves well to making conceptual changes that would allow exploration of design alternatives. Small wonder some architecture schools experience a division between computer and studio courses, or even between computer and studio faculty. Different ways of talking and thinking are involved. The concepts involved are often mutually exclusive. This paper discusses an attempt to address this conceptual mismatch, using what are termed “protean” (meaning “very changeable”) elements. These are high-level elements corresponding to architectural concepts like “wall,” or “dome.” They each have parameters appropriate for the particular type of element they represent, and produce the polyhedra necessary for graphics based on these parameters. A system is being implemented to allow models to be constructed using these elements. The protean elements form a loosely structured model, in which some elements hierarchically contain others, and some elements are essentially freestanding, being created and manipulated independently of other elements. Characteristics of protean element are discussed, including the underlying object-oriented structure, the relationship between elements and graphics, and functions associated with the objects. A scheme is explained whereby all parts of a design can be represented even when the design includes extremely unusual forms not conforming to predictable classes of elements. The necessary support framework is also discussed; general flow of the system and mechanisms for viewing the model and editing subcomponents are explained. The current status of the project, and intentions for future work are discussed. The project has been partially implemented, and the necessary framework to support the system is mostly complete.

source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	This paper presents the basic ideas of a computer system for supporting urban design and decisions on land use. We argue, that the high complexity of urban design - inherent in the its large number of interdependent views and aspects - seems to justify a flexible support system capable of reasoning and conceptual modelling. Such a system may be prohibitively resource demanding unless we are able to build it up from smaller and larger modules of different types and functionality and which canbe created basically in an incremental way without a complete plan in advance. Two prototypes concerning urban designs and a small flexible design rule interpreter/handler is presented for free standing buildings.

title	The Virtual Design Team
source	Communications of The ACM, Vol. 41, No. 11, November, 1998
summary	The long range goal of the Virtual Design Team" (VDT) research program is to develop computational tools to analyze decision making and communication behavior and thereby to support true organizational (re)engineering. This article introduces the underlying theory, the implementation of the theory as a computational model, and results from industrial test cases. Organization theory traditionally describes organizations only at an aggregate-level, describing and predicting the behavior of entire organizations in terms of general qualitative predictions. We define and implement a "micro" theory of the structure and behavior of components of organizations, explicitly representing activities, groups of people called "actors," and organizational structure and policies for project teams. A VDT model can be "run" by a discrete event simulation. Emergent aggregate model output behaviors include the predicted time to complete a project, the total effort to do the project, and a measure of process quality. More detailed model behaviors include the time-varying backlog of individual actors and the "exceptions" associated with activities. The results are detailed and specific, so they can guide specific managerial interventions in a project team and can support sensitivity studies of the relative impact of different organizational changes. We conclude that such a theory is tractable and predictive for complex but relatively routine, project-oriented design tasks. The application for which VDT offers unique new kinds of insights is where an organization is striving to shrink time to market dramatically for a product that is similar to ones it has previously developed. Reducing time to market dramatically almost always requires that previously sequential activities are executed more concurrently. In this situation, experienced managers can still correctly identify the required activities and estimate their durations and skill requirements; but they almost always underestimate the increased workload arising from exponentially higher coordination needs and the propagation of rework between the now highly concurrent activities. The VDT framework, which explicitly models information dependency and failure propagation between concurrent activities, has proven to be far more accurate, and to incorporate a wider range of parameters, than CPM/PERT process models for these fast-paced development projects."

title	Criteria for an object oriented library system of high–level parametric CADelements

summary	The subject of this paper is the development of criteria and specifications for an object oriented library system of high–level parametric elements that have an integrated 2D and 3D representation. High–levelelements are virtual representations of architectural elements such as windows, doors, etc. High–level parametric elements need few components to be flexible and easily customizable. The generalization ofeach element by its characteristic parts results in a substantial reduction in the number of polygons that must be processed by the computer during the 3D transformation, graphically clean 3D images and low demandon user intervention. Gestalt theory emphasizes the importance of contour lines for the perception of an element. The “minimalist” symbolic representation will simplify contour lines that enhance perception. Theinherent flexibility and functionality of object oriented elements are augmented when the elements are rigorously developed as an object oriented library system, with classes and sub-classes of elements whichinherit characteristics of the parent–class. Attribute values of a parent–class give the user global control over all instances of that class and its sub–classes in the model’s database. The concepts which SystemsTheory uses for making an abstraction of reality are analogous to the concepts used in object oriented programming. This paper describes how Systems Theory is used as tool to develop high–level parametric elements as a functionally and computationally efficient library system.

title	A practical experiment in representation and analysis of buildings
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	The TYPOLOGY project was set up by the Dutch Government Building Agency (GBA) to explore computerised representations of buildings that allow analysis of various aspects of their performance. So far this project produced the RF-model, an abstract computerised representation.Physical elements of the building are not represented as such, only individual spaces and boundary segments along which they are adjacent are represented explicitly. Spaces can have any number of functional properties such as the general category of floor area they are included in, the activities they accommodate, or the particular safety compartment or circulation system they belong to. Similarly, boundary segments may, for example, provide access or view, may be included in a particularcategory, such as interior walls, or in a safety or security barrier.The RF-model enabled the presentation and quantitative analysis of design proposals for large and complex buildings such as courts of justice and prison buildings. The model is also used in a multiaspect analysis of a series of recently erected Dutch prison buildings. We expect that these first results will develop into a rich and professional precedent-based system, to be used in the early stages of design. The strategic goal of the project is to derive from the accumulated models and their analysis a more general understanding of the relations between a building’s actual characteristics and various aspects of its performance.
