title	A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary	Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

source	The Virtual Studio [Proceedings of the 12th European Conference on Education in Computer Aided Architectural Design / ISBN 0-9523687-0-6] Glasgow (Scotland) 7-10 September 1994, pp. 127-134
doi	https://doi.org/10.52842/conf.ecaade.1994.127
summary	Pointing towards the ultimate goal of instrumental integration between our instructional and professional environments, the paper deals with the articulation of small scale R&D projects that, due to their consistency with main-stream tendencies, can have considerable impact on allowing people, institutions and enterprises to perform a relevant role in our dynamics of "Continuing Professional Development" and "Practice-Based Learning". The paper presents the results of a European Union R&D Project that aims to empower small and medium size enterprises of the building sector with the knowledge needed for the development of multimedia programmes with pedagogical value. The paper is explicit on addressing not only the achievements but also the difficulties that the consortium of European partners had to face, and makes reference to a future spin-off project that follows the same tactical approach.

title	A Taxonomy of Architecture: Core of a Theory of Design
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	The authors developed a taxonomy of concepts in architectural design. It was accepted by the Advisory Committee for education in the field of architecture, a committee advising the European Commission and Member States, as a reference for their task to harmonize architectural education in Europe. The taxonomy is based on Domain theory, a theory developed by the authors, based on General Systems Theory and the notion of structure according to French Structuralism, takes a participatory viewpoint for the integration of knowledge and interests by parties in the architectural design process. The paper discusses recent developments of the taxonomy, firstly as a result of a confrontation with similar endeavours to structure the field of architectural design, secondly as a result of applications of education and architectural design practice, and thirdly as a result of theapplication of some views derived from the philosophical work from Charles Benjamin Peirce. Developments concern the structural form of the taxonomy comprising basic concepts and levelbound scale concepts, and the specification of the content of the fields which these concepts represent. The confrontation with similar endeavours concerns mainly the work of an ARCUK workingparty, chaired by Tom Marcus, based on the European Directive from 1985. The application concerns experiences with a taxonomy-based enquiry in order to represent the profile of educational programmes of schools and faculties of architecture in Europe in qualitative and quantitative terms. This enquiry was carried out in order to achieve a basis for comparison and judgement, and a basis for future guidelines including quantitative aspects. Views of Peirce, more specifically his views on triarchy as a way of ordering and structuring processes of thinking,provide keys for a re-definition of concepts as building stones of the taxonomy in terms of the form-function-process-triad, which strengthens the coherence of the taxonomy, allowing for a more regular representation in the form of a hierarchical ordered matrix.

title	Applying Visual Design: Trade Secrets for Elegant Interfaces TUTORIALS
source	Proceedings of ACM CHI'94 Conference on Human Factors in Computing Systems 1994 v.2 pp. 353-354
summary	This tutorial describes a number of fundamental techniques applied routinely in communication-oriented visual design. The orientation, process, training, and culture of the visual design disciplines (graphic design, industrial design, interior design, architecture) are essential components of effective interface design. Unfortunately, few software developers or human factors engineers receive any training in these disciplines. This tutorial describes important design rules and techniques internalized by every visual designer through coursework and studio experience. While mastery will indeed require extended practice, the techniques we describe are not difficult to understand and can be immediately applied to real-world problems. We draw our background, training, and influence from the rational, functional, information oriented perspective of the Modernist design ethic. Because all graphical user interfaces are communication systems, we believe their design should reflect these same values. Our tutorial is organized not along the traditional subdisciplines of color, typography, or ideation, but along the problems of graphical interface design as experienced in commercial software development. We describe basic design principles (the what and why), common errors, and practical techniques (the how) for each of the six major areas outlined below. (1) Elegance and Simplicity (2) Scale, Contrast and Proportion (3) Organization and Visual Structure (4) Module and Programme (5) Image and Representation (6) So What About Style?

title	The Management of Knowledge in Architectural Companies by Reconstruction of Problem Solving Systems
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	The purpose of this paper is to present a theory for 'knowledge management' in architectural firms. This theory is based upon the premise that knowledge as well as employees (..the designer as a knowledge worker..) are regarded as means of production and that for both of these resources economic values exist during a limited period of time. Similar to the management efforts to optimize the use of labour and 'material' equipment the use of knowledge should be optimized by adequate management. The presented theory for the management of knowledge introduces a new profession in the organization of an architectural firm: the knowledge manager. And within this context a knowledge base is regarded as a tool to help to perform one of the tasks of this professional. The central part of this theory consists of a cognitive reconstruction of problem solving systems. This reconstruction provides a layout for a knowledge base as well as a 'road map' to guide the discussions on 'what knowledge is used', 'who learned what' and 'to whom must experience be transferred'. Employees as the most 'cognitive actors' in problem-solving in design processes can be traced. The management can decide on wether to emphasise the concentration of knowledge by these persons or to emphasize the transfer of their knowledge to others. The use and meaning of knowledge bases for each of these management approaches are completely different.

title	Maximising the Benefits of CAD Systems in Architectural Education
source	The Virtual Studio [Proceedings of the 12th European Conference on Education in Computer Aided Architectural Design / ISBN 0-9523687-0-6] Glasgow (Scotland) 7-10 September 1994, p. 228

summary	The positive impact of Computer Aided Design (CAD) in professional architectural practice has been in focus in recent times but relatively little has been written on its significance in the education of the contemporary architect. It is common knowledge that the profession of architecture is currently undergoing enormous strains as it battles to keep abreast of trends and developments in a period of series of rapid advancement in science, technology and management (RIBA, 1992). Whilst attempts are being made to redress the shortcomings of the profession in the above context, the requirements for architectural education are yet to forge a coherent strategy for the implementation of CAD/IT in the curriculum of schools of architecture. In almost every other field, including engineering, medicine and the humanities, computing application to problem-solving and decision-making is seen as a way forward as we move into 21st century. Architectural education must integrate CAD/IT into the teaching of core modules that give the architect distinctive competence: studio design. That is one of the best ways of doing justice to the education of the architect of today and the future. Some approaches to the teaching of CAD in schools of architecture have been touched upon in the recent past. Building upon this background as well as an understanding of the nature of design teaching/learning, this paper examines ways of maximising the benefits of CAD systems in architectural education and of bringing computer aided designing into the studio not only to enhance design thinking and creativity but also to support interactive processes. In order to maximise or optimise any function, one approach is to use the hard systems methodology which utilises analytic, analogic and iconic models to show the effect of those factors which are significant for the purposes being considered. The other approach is to use the soft systems methodology in which the analysis encompasses the concept of a human activity system as a means of improving a situation. The use of soft systems methodology is considered more appropriate for dealing with the problem of design which is characterised by a flux of interacting events and ideas that unroll through time. The paper concludes that the main impediment to maximising the benefits of CAD systems in architectural education is not only the inappropriate definition of the objectives for the implementation of CAD education but also that the control subsystems are usually ill-structured and relatively poorly defined. Schools must attempt to define a coherent and consistent policy on the use of CAD systems as an integral part of studio design and evolve an in-house strategic and operational controls that enable the set objectives to be met. Furthermore, it is necessary to support the high level of productivity from CAD systems with a more efficient management system, especially in dealing with communication, data sharing via relational database, co-ordination and integration. Finally, the use of soft systems methodology is recommended as the way forward to optimising CAD systems in design education as it would provide continuous improvements while maintaining their productive value.

title	A digital Procedure of Building Construction: A practical project

summary	In earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.

title	First Drawings, Then Semantics

summary	The Semantic Modeling Extension (SME) prototype implements a unique approach to integrated architectural CAD that places the drawing act first in the design process. After drawing a design idea using a computer graphic system, the designer interprets the design, providing semantic content to the graphic entities. An interpretation expresses the meaning of the design with respect to a particular issue, such as structural sufficiency, energy consumption, or requirements for egress, and provides reasoning to evaluate the design addressing that issue. A design may have many interpretations to express the multiple issues that are relevant in a design project. The designer may add or delete interpretations of the design as issues change during the course of the project. Underlying the SME prototype are the concepts of form, function and behavior. In the prototype, evaluation of a design is done by deriving behavior from the graphically represented forms and relating the behavior to stated functions or requirements. The concepts of interpretations and form, function and behavior together establish a virtual product model for design. In contrast to component based approaches to product modeling that tightly bind form representations to their behavior and function, a virtual product model allows the designer to manipulate the relations among these three descriptors of a design, and thus manipulate the semantics of the design entities. By distinguishing between the act of proposing a design by drawing the conceived form and the act of assigning meaning to the form, the virtual product model approach supports both graphic thinking for design synthesis and symbolic reasoning for design evaluation. This paper presents a scenario of the use of the SME prototype in building design; provides an analysis of the design process and computational support described in the scenario; contrasts a virtual product model approach with a component-oriented product model approach; describes the software implementation of SME; and presents implications and conclusions regarding design process and technical integration.

title	Problems of Chronology, Decoration, and Urban Design in the Forum at Pompeii
source	American Journal of Archaeology, vol. 08, no. 4, October, pp. 629-694
summary	This article offers an archaeological and structural analysis of the four main buildings on the east side of the forum at Pompeii and challenges widely published and generally accepted views about the forum. Major problems of chronology, decoration, and urban design are emphasized through a methodology that rejects the prevalent building-by-building approach to the forum in favor of an approach that allows the significance of the urban ensemble to reveal itself. Connections with Rome in areas of building type, iconography, and design are stressed. A reexamination of the evidence points to a comprehensive post-earthquake (i.e., post-62) plan for the east side of the forum, a design whose hallmarks are the unification and monumentalization of the urban center. These goals were achieved by blocking streets, linking facades, upgrading building materials, and emphasizing the now more prominent northeastern and southeastern entrances. The concomitant economic implications are significant. Rather than being a symbol of the depressed economic conditions at Pompeii after 62, the forum with its vigorous and ambitious post-earthquake building program reveals both a de- sire to rebuild on a grand scale and an ability (with assistance from Rome?) to carry it out.

title	Visual Reference for Design: Analogy, Transformation and the Act of Sketching
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	All designers know that it is impossible to infer a design solution from the givens of a task alone, no matter how complete and well presented they are. Therefore, designers seek to complementinformation they receive, and the material they bring into the task environment includes visual images. Images may be gathered from every imaginable source, from domain-specific images (in architecture they are usually classified and pertain to building type, location, period, technology, style or creator) through 'metaphoric' images (art, nature) to eclectic personal favourites. Inaddition, randomly encountered images may find their way into a database of references: a depository of potentially useful images. With the exception of factual information that fills in thetask givens, it is usually far from clear what purpose may be served by images in general, or to what use the specific images aligned for a particular task may be put. We propose that the singlemost significant 'on line' role of visual references during the process of designing is to suggest potential analogies to the entity that is being designed. The process of discovering and exploitingan analogy in design is complex; we shall explain it in terms of Gentner's structure mapping theory, which we adapt to visual structures. We further propose that the abstraction process thatmust take place for the successful identification and mapping from source (visual reference) onto target (designed entity) requires transformations of images, and such transformations are bestachieved through sketching. Sketching facilitates the two way process of movement from the pictorial to the diagrammatic and from the schematic to the figural. Such transformations musttake place to arrive at the match that allows conceptual transfer, mapping of structural relations and insight through analogy.

source	Beyond Tools for Architecture [Proceedings of the 5th European Full-scale Modeling Association Conference / ISBN 90-6754-375-6] Wageningen (The Netherlands) 6-9 September 1994, pp. 23-30
summary	How to develop an attractive built environment with the desired housing and well kept outdoor conditions? As long as experts do not ask lay-people for their needs and wants, we must not be surprised that people are not interested in their environment and show a lack of care. The contribution of (future) inhabitants in the planning process can have a material and a social impact on building, improving and maintaining a neighbourhood. One of the problems that have to be solved is the question how to improve the communication between non-professionals and professionals, between inhabitants and designers (architects). Inhabitants express themselves in a simple language about the number of rooms, cupboards, size of the garden and parking place. Architects communicate in drawings of designs and talk in a technical language about functions, forms, spacial structures, light and expression. It can be helpful - is the fundamental idea in Wageningen - to develop a shared language, to start talking about activities and to use scale models in a structured process. The participation process is a sort of exploratory expedition. Good communication is a must for a successful participation process. A clear expression of the 'programme of habitat wishes' is the first step in the dialogue between inhabitants and architect. The Structural Space Planning Method is a structured process to develop a 'programme of habitat wishes' for the built environment. It can be related to all sorts of objects: houses, co-housing projects, institutions, playgrounds, streets or neighbourhoods. Full scale and scale models are part of the Structural Space Planning Method, as described by Van Dam (these proceedings). This contribution describes some practical experiences with the development of the 'programme of habitat wishes' and the effects on the participation process.

title	Building Integration Tools for Collaborative Design
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	For many years, research in CAAD systems has been mostly oriented towards single environ-ments, thus restricting the designer to a static environment. In reality the activities of user designers constantly interact with other participants activities (i.e. a structural engineer, services engineer, etc.). For instance, the architect is heavily influenced by the nature of the structural engineering process. It defines the character and integration of the basic components in other words, design is a collaborative process carried out by several participants with a single overall objective. The separation of architectural and engineering aspects in building design has brought on isolated computer tools. These tools are not interchangeable, the situation demands for their integration, all the interaction are supported by the social aspect of members of group participa-ting in collaborating work. The benefits of sharing CAD tools and related data between all members of the design team are that everyone works on the same information, co-ordination is easier and more accurate, and there is a reduction in the amount of repetition, as the need to redraw information is eliminated. The result is an increase in the accuracy and speed of the production of drawings. The technological aspects to support collaborative work and in particular the interaction process in design, is the main work issue being carried out at Strathclyde University, Department of Architecture and Building Science, Glasgow, Scotland U.K.

title	Development of an Expert Cad System for Visual Design of a Bridge in a Landscape
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	Architects, landscape architects and urban designers are often required to be involved in the process of bridge design from an aesthetic point of view. The authors have been developing a comprehensive CAD system to support such visual design works, especially at an early stage of design. Conventional complicated technical standards and guidelines tend to discourage creative design. In order to support free conception and creation of bridge forms, this system includes a visual design core system as a workshop, even enabling freehand sketch drawing on existing landscape images of the site. This is supported by a landscape simulation subsystem. The system can also provide initial design ideas with several different types of bridge form, derived from knowledge based subsystems on design guidelines and precedent examples which can be quoted also to examine the physical possibility of sketch drawn alternatives in terms of structural dimensions and construction costs. Created design alternatives will be analyzed by a visual impact analysis subsystem to assess their influences on surrounding environments from a visual geometri-cal standpoint. This system is intended to enable architects, landscape architects or urban designers to create and examine design alternatives on a real-time basis.

title	Some Phenomena of seeing shapes in design
source	Design Studies, v 16, n 3, pp. 367-385
summary	This paper is a look at some of the pyschological results that suggest how shape emergence manifest itself in the human mind. The first interesting result goes back to top down expectation guiding recognition. Some experimental suggest that it is easier (quicker) to recognize shapes which we have some alternate mental familiarity. (I.E. verbal, structural descriptions). So if we can easily say a shape then we can easily discern it as an emergent shape. The paper then goes on to discuss the definition of emergent subshapes and gives various authors definitions of what makes up and emergent shape. One interesting classification is the difference between explicit and implicit emergent shapes made by Mitchell. This difference amounts to a fine line between imagination and emergence. The results of an experiment between experienced and in-experienced designers is discussed. The results suggest that experienced designers are able to find more emergent shape than non experienced designers. From these results and from the opinions of others, the author goes on to specify 3 phenomena related to emergent recognition. The first is as above that it is easier to see shapes with which we are familiar. Second from this, the harder shapes are found after the initial period. Third, from the first two, time is required to find more subshapes. The author then searches for an explanation of this phenomena. He suggests that the underlying cause is related to an experience person having a lower threshold of what it is to be a member of a shape. When seeing an L shape the experienced design is likely to consider it also a square, because his requirement for the set of features which must be present for some object to be a considered a square is a smaller set than the inexperienced. While the author suggests that this is a phenomena it is actually an hypothesis. An alternate hypothesis may be that top down inhibitions effect the bottom up performance of the inexperienced design more because of different representation.

title	PLACE, TIME AND THE VIRTUAL DESIGN STUDIO
source	Reconnecting [ACADIA Conference Proceedings / ISBN 1-880250-03-9] Washington University (Saint Louis / USA) 1994, pp. 115-132
doi	https://doi.org/10.52842/conf.acadia.1994.115
summary	A design problem shared over the Internet raises issues of how digital media and group dynamics affect networked design collaborations. This paper describes how to conduct a long-distance studio and compares asynchronous and synchronous collaborative techniques. Digital methods are discussed in relationship to both the creative process and design communication. In schematic stages, less precise tools used asynchronously allow free exploration and creative misreadings, while in later stages, more direct real-time exchanges bring a project to resolution. For the final review, synchronous video-conferencing with interactive graphics allow comparison of cross-cultural differences. Used effectively, these tools can electronically create a compelling sense of place. Ways to foster a strong virtual community are discussed in an agenda for future virtual design.

title	A Strategic Planning and Policy Decision Support Tool for Urban Regions
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	In this paper we present a Decision Support System developed to assist urban designers, planners and policy makers to explore and evaluate possible urban layouts and their growth patterns. Thecore of the system consists of a modelling shell allowing the user to specify cellular automata based models of urban and regional systems. These models capture the effect of local spatial processes in which the use, or desired use of each parcel or cell of land is determined partly by institutional and environmental factors, and partly by the activities present in its neighbourhood. Since each cell affects every other cell within its neighbourhood, a complex dynamic emerges. Unlike conventional cellular automata, the models are defined with a large neighbourhood --over a hundred cells-- a relatively large number of states --more than a dozen in some applications-- representing socio-economic and natural land-uses. The approach permits the straightforward integration of detailed physical, environmental, and institutional constraints, as well as including the effects of the transportation and communication infrastructure. These models thus permit a very detailed representation of evolving spatial systems. The current version of the system represents urban areas as consisting of up to 10.000 interacting zones, each roughly the size of an individual city block. These models are easy to build and apply, yet empirical tests show that they produce realistic simulations of urban land use dynamics. Consequently, they are well suited to form the heart of the DSS, which provides the user with a number of tools for exploration,analysis and evaluation of alternative futures of the system as they result from policy interventions that are imposed by means of what-if experiments and scenario analysis. For example, the DSS isable to identify areas in which pressure for change in land use restrictions may become critical under particular development strategies. In the DSS, the modelling shell is coupled to a simple,custom-built GIS. In the stand-alone application of the DSS, this stores the detailed geographical qualities of the area being modelled, and allows basic overlay manipulations. It also displays theresults of the model while the simulation proceeds. Alternatively, the GIS can serve as aninterface to more elaborate, commercial GIS systems.

title	Control of Parts: Identifying Patterns of Control in Production Chains
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	If we examine the stages of production of complex physical systems, we notice that parts change as they progress along a value chain. Parts are deformed, have parts removed, and are assembled and disassembled, in various sequences. In such processes, production operations (milling, cutting, aligning, attaching, and so on) are of particular interest, as are the sequences of production, since some operations and sequences have been found to be more efficient than others, lead to fewer mistakes and produce higher quality results. Research continues to be produced seeking to optimize production operations, sequences and product quality. The production operations we can observe in the making of artifacts are also of interest because they are by definition the result of action taken by certain agents. Parts are changed or controlled by human beings, employing their own hands or sophisticated machines. Today, we are used to making a distinction among agents involved in production: some agents specify what is to be made, and others make what is specified. One agent can do both, but specialization and division of labour has presented us with this distinction. This is now conventional, aside from whether it is "good" or not. The distinction is the basis for the interest in "concurrent design and production of products", the renewed focus on distribution and coordination of work in teams, and the related interest in understanding the dynamics of building systems in terms of the agents who control them. This paper focuses on the place certain kinds of agents take in complex production flows. Since production of parts is both a technical and a social enterprise, we will discover, when we look closely, complex webs of interactions which can be mapped, showing how agents relate to each other through the parts with which they are concerned. In examining the class of agents who control parts, we can see two patterns of control, termed DISPERSED PATTERNS and OVERLAPPING PATTERNS. These become palpable in a graphic diagramming tool, which is demonstrated in what follows. These diagrams also provide a means to consider the agents whose role is to specify what is to be made. The paper includes notes related studies in other fields.Finally, the paper suggests how this perspective can be useful, and several research topics based on it are sketched.

title	A Functional Framework For Conceptual Modelling
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	A conceptual model is not only indispensable for the design and implementation of knowledge based systems, but also for their validation, modification, maintenance and enhancement. Experience indicates, however, that in many cases reality is not well reflected in a full-fledged conceptual model. What is systematically lacking in the prevailing conceptualization methods is a well-developed theory of knowledge that underlies conceptualization methods: a theory that precedes the process of forming meaningful classifications and that precedes the specification of a conceptual model. To date, conceptualization methods are based on the probabilistic assumption that, in essence, all conditions necessary for creating a classification, are provided initially and can easily be revealed by utilizing mathematical measures of similarity. Another frequently occurring prototypical assumption is that for creating a classification, necessary conditions are sufficient. Furthermore, it is assumed that the categories of conditions are a priori fixed and unconditional. That conceptualizing takes place without any explicit background knowledge about goals of classifications and without contextual influences and that categorizations have an unconditional status are not viewed as problems. In contrast to these approaches, the functional view states that relevant descriptive attributes are not necessarily a priori given but should be acquired through knowledge about goals of classifications and about contexts. It is also asserted that an explicit concern for necessary conditions will not suffice for capturing the dynamics of reality. Furthermore, the functional view puts forward that a goal- and context-oriented strategy leads to the reconstruction of new attributes and categorizations with a dynamic status. The aim of this paper is to discuss the theoretic and practical merits of the functional view compared to the probabilistic and prototype approaches. Conceptual models developed in the Computer Integrated Manufacturing-Project will serve as illustrations for the main ideas.
