title Urban Configuration, Attraction And Morphology
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Spatial Interaction (SI), based on the principle of attraction, has set up a powerful way of looking at the behaviour of urban systems. Within-place activities generate and/or attract trips, due to their inner fragmentary nature; several activities articulate a system of locations and flows which is supposed to be regulated by concentration of those activities and distance between them'. SI has been criticized for having a poor theory and little regard to spatial specifics. In general terms, planners and large-scale urban scientists have been more comfortable with it than designers and urban morphologists, whose questions about space configuration are awkwardly dealt with in such a framework. Recently, Space Syntax (SS) has been suggested as an alternative to describe possible roles of space in the urban system. Its theory looks very complex - a deep cultural, anthropological connection between man and space, an atavistic impulse driving the shaping of space. Teklenburg et al have shown, however, that it is, in fact, very simple and not far from the rude assumptions of SI: a matter of distance and orientation3. Hence, what does look new is just its way of describing orientation, through the axiallity of public space. Axial lines retain the fundamental issue of connectivity; so they describe space more efficiently than the traditional zones or links used in SI models. SI says little about configuration, SS says little about interaction between spaces and activities, and both say nothing about morphology, or the configurational development of urban systems. An alternative approach is suggested: (i) urban spatial configurati-on (urban grid and built form) strongly conditions activity location and flows, in the short term. In this way, a convenient description of such a configuration should denounce its potential to housing activities and generate flows. This required description should take the grid axiallity as a measure of connectivity and orientation, as in SS, as well as the built form as a measure of attraction, as in SI; (ii) activity location and flows strongly conditions urban spatial configuration change, in the long run. Location and flow patterns create values that are expressed by an increasing conflict between rising land values and declining building values. As a result, configuration is taken as a particular state of a morphology whose transformation rules are an economic expression of spatiality. Flows are cause and effect in the lagged process of mutual transformation which shapes the urban space.

title Impact-Analysis of Urban Design Realtime impact-analysis models for urban designers
source Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary The past five years Prof Dr Jr T.M. de Jong, professor in environmental planning and sustainability at the Technical University of Delft, has developed a theoretical foundation for the analysis of urban design on the ecological, technical, economical, cultural and political impacts of morphologic interventions on different levels of scale. From september 1994 Jr AJ. Boelen (Urban Design Scientist and Knowledge Engineer) started a research project at the same university to further explore the possibilities of these theories and to develop impact evaluation models for urban design and development with the theoretical work of De Jong as a starting point. The paper discusses the development of a design and decision support system based on these theories. For the development of this system, techniques like object-orientation, genetic algorithms and knowledge engineering are used. The user interface, the relation between the real world, paper maps and virtual maps and the presentation of design-interventions and impacts caused by the interventions are important issues. The development-process is an interactive step by step process. It consists of the making of a prototype of the system, testing the theory and hypothe-sisses the system is based on, by applying tests end adjusting the theory and hypothesisses where needed. Eventually the system must be able to act as an integrator of many different models already developed or still to be developed. The structure of the system will allow easy future expansion and adjustment to changing insights. The logic used to develop the basic theory on which this system is founded makes it possible to even introduce and maintain rather subjective aspects like quality or appraisal as impacts that can be evaluated. In a previously developed system "Momentum" this was proved to work effectively for the national level. In this project we will - amongst other things - try to prove the effectiveness of impact-evaluation for other levels of scale.

title Mastering Urban Network Intersection And Superimposition, in an Object-oriented Knowledge System Integrating Rules, Neurons and Processes
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Many networks cover the urban texture, either superimposed at a variable distance, or really intersecting, or even in interconnection. We briefly recall the HBDS model, working on persistent abstract data types associated to graphical representations and carrying algorithms expressing conditions to be verified and/or actions to be performed. HBDS is an integrated system too, including database, expert system dealing with fuzzy rules and facts, discrete simulation engine, and neural engine; it has a general purpose programming language. Any urban network is associated to a given prototype, according to the same scheme named prototype with more specific components. These prototypes allow to build the different thematic structures instantiations of the prototypes. All possible cases of arc intersection or "pseudo-intersection" (simple superimposition)or interconnection are obtained by, owing to new prototypes. Moreover, such (pseudo)-intersections are automatically recognized and processed without a human intervention, owing to classes ofconstraints and classes of rules. They deal with particular constraints concerning the location of some urban furniture, and rules concerning the way a cable or a pipe must follow according to thepre-existing other networks in a given area, the minimal distances, minimal or maximal depths, and some required equipments. Urban classes of (pseudo-)intersections inserted in the hyperciass"neuron", inheriting of neural features, may be used for automated learning of urban knowledge; owing to their "behavior", these neurons can communicate and perform actions on other components. Urban classes inserted in the hyperciass "process" may be used for building very large models simulating complex urban phenomenons, thus allowing a better understanding of the real phenomenons. As a conclusion, we emphasize the methodological aspects of object-oriented integration for an efficient processing of the urban context, based on prototyping and mixing rules, neurons and processes.

title THe "Allots" Model: A PC-Based Approach to Demand Distribution for Siting and Planning
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary This paper reports on the development and application of ALLOT: a user-friendly, flexible computer model which has been designed to help governmental jurisdictions and private landowners throughout the world to achieve more economically efficient and environmentally sound land use and development patterns in a short period of time. ALLOT has the potential to drastically change the way that land use planning is conducted, since it has the capability to allow theincorporation of a wide variety of previously ignored environmental characteristics and up-to-date land use patterns. ALLOT, which is written in the SAS programming language, contains twomajor parts. The first part employs a GIS database to conduct land suitability analyses for the area. It then produces maps showing the most suitable areas for various land use types. The second part appears to be unique in the field of computerized land use planning models. It combines the results of the suitability analysis with forecasted demand for various land use types to produce "optimum" future land use patterns. The model is capable of quickly analyzing a wide variety of forecasts, allowing easy comparison of different growth scenarios; and it can also be modified to reflect community goals and objectives, such as protection of wildlife habitat orattraction of industry. The flexibility, combined with the fact that it runs on any IBM-compatible PC (286 or higher), make it a powerful land use planning tool. The model has been successfully applied in two "real world" situations. First, three alternative future land use patterns were developed for a rural lakeside area. The area had rural characteristics and was lacking infrastructure, but a large influx of people was expected as the lake was filled. The success of this effort led to decision to test it´s use as a method for facility siting (using landfill siting as an example).

title Historical Background of the Visual Simulation Models in Architectural Design
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary It is well known that every sort of visualization model has its own capacity to represent the reality and designers' concepts of space. To the authors' knowledge, there are very few attempts to measure and compare their relative potential power of presentation. Given this lack of academic studies, it would be necessary to give a historical background on the use of visual models. Basically those tools could be divided into two main types : traditional visula techniques such as drawings , scale models and most advance technological tools ranging from basic slidesand films to recentlydeveloped techniquessuch as relatoscope, and computer aided simulation models. This paper covers the historical background of visual models .

title Graphical Knowledge Interfaces: The Extensive and Intensive Useof Precedent Data Bases in Architecture and Urban Planning
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Space syntax' is a family of techniques for the analysis of architectural and urban space which can be used both in research and design mode. This means, for example, that a redevelopment area in an urban context can be researched using space syntax models which can then be turned round and used as the basis for design idea of a 'graphical knowledge interface' (GM) is a further development of this in feeding research into design. It starts from the important role that the analysis and comparison of 'precedents', that is, cases with some similarity of the design problem in hand, often play in design. In a GM, 'precedents' which have already been researched using the space syntax methodology and which are relevant to a particular design problem - say a set of urban areas or a set of housing estates - can be brought into the modelling technique, so that the designer has on hand not simply a space syntax model of the problem in hand but an intelligent 'precedent' in the form of graphical and statistical representations which can be manipulated and interrogated during the design process, in much the same way as discussion of precedent are currently brought into design but with much more complex data and much more powerful theoretical tools. GM can be used as intensive mode, in which many different kinds of data - say on land uses, rents, or crime rates - are added to the model of an area, or in extensive mode where the emphasis is on comparing, say, the structures of a large number of urban areas. The GM will be illustrated through a worked example of a recent major urban design project in which the team has participated.

title Psychology of Early Design in Architecture
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Lately there has been a good deal of emphasis on the early stages of the design process, particularly by developers of computer aids and quantitative design models for both evaluation and generation of designs in a variety of domains. Yet, there is little understanding of the early design-process. While the early design process as manifested by human designers need not be the sole basis of the description of this phase, it certainly represents and important kernel of knowledge, especially for those who are interested in developing models, systems or merely interfaces for such systems. This paper focuses on the characterization of the psychology of the early design phase in architecture. It is described in terms of the general design strategies and problem solving tactics used; and is contrasted against some of the process characteristics that

title APPLICATION OF FULL-SCALE MODELLING IN VIETNAM: AN OUTLINE FOR DISCUSSION
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. 59-70
summary This paper discusses the possibility of applying full-scale modelling in Vietnam, a non-western so called developing country. It deals with two main questions: 1) Is the application of full-scale modelling to be restricted to the West only? 2) what are the possibilities, constraints and fields of application - with attention to the methodological validity and technical solution for full-scale modelling in Vietnam? It is argued that since full-scale modelling is based on people-environment interaction, it should, in principle, apply to studies about people–environment relation anywhere on earth. On the methodological validity, it is discussed that application of full-scale modelling in Vietnam faces similar methodological problems as encountered in European applications (such as people's behaviour in experiment, ability to understand the abstraction of models, etc.) although at another level as this paper will make clear. However, it would be needed to design a modelling kit that is of low costs and adapted to the availability of local materials and suitable for the climatic condition of Vietnam. Two fields of application are projected as most applicable in Vietnam: modelling in architectural education and research investigation. Application for user's participation in the design process will depend on the development of building policy in the country.

title A Multi-Purpose Multi-Stop Model Describing Consumers' Choices of Shopping Centres
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Recently, a number of interesting extensions to traditional decompositional and discrete choice models has been introduced that allow one to combine parameters estimated in different phases ofcomplex choice processes. These extensions offer new possibilities to model combinations of choices consumers make if they select shopping centres to visit. This paper will introduce a modelling approach that describes consumer choices of shopping centres involving multiple shopping functions (multi purpose) as well as locations (multi stop). The approach extends traditional decompositional models of single choices to a model of combinations of choices. It uses a recursive scaling procedure that combines attributes related to different shopping functions and to shopping centres at different locations. The model will be tested on data collected on shopping behaviour in Maastricht, the Netherlands.

title The Design of Decision Support Systems in Urban and Regional Planning
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Planning methodology over the years, has shifted from situations whereby planners think, plan and design for the people to one whereby both people and planners have become important components of the planning process. Consequently, the important urban planning methodology of the last two decades that utilized mathematical models in the planning process is fast becoming obsolete. The paper argues that model building should move to the creation of urban decision support systems for the planning process through the development of expert systems shells that interfaces existing planning models with the knowledge content of planning and planners. The expert system shells as the set of decision rules for determining how existing supply and demand relationships are applied for modelling land use and transportation would be responsible forguiding the development of appropriate geographical information systems, supporting land use and other models in a coordinated manner, for communicating with these other systems componentsand for guiding interactions between them and the user. Furthermore, decision support systems should be designed to bring the whole of the knowledge base to bear on a problem through a flexible and adaptive solution system that makes explicit use of both the analysts models and the decision makers expert knowledge. It is argued that this understanding leads to the development of three crucial issues for the design of decision support systems in urban and regional planning;namely the development of user friendly integrated urban land-use transportation models, the development of expert geographical information systems and the development of expert systemshells for many of the routine tasks planners deal with.

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

title Hypermedia-aided GIS in Urban Planning
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Town planning in Denmark is undergoing major changes from a planning approach focusing on regulation and individual frameworks for town districts, to a planning approach emphasizing the urban characteristics and drawing overall guidelines for planning. At the same time, attention has shifted to urban renewal and urban remodelling. This means that more qualitative data are needed.These new data types such as digital film, are to form part of a future GIS for the town. The digital film will change the impression of what data can profitably be used in a GIS. Even animations and 3D models, which were previously processed with considerable data power can beplayed as digital films. In the course of the next few years, the most ordinary applications will be able to play digital films and together with the progress made in other media, a development towards hypermedia will be a possibility. The paper will give some examples of how this integration may be carried out. In continuation of the preparation of a municipality atlas and in connection with an EC-subsidized urban renewal project, the municipality of Aalborg has chosen to work outa digital catalog which will in time replace the present local planning regulations.

title Matchmaker: An Instrument for Matching Demand for and Supply of Buildings and Revealing Specific Discrepancies
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary To match supply and demand of buildings, various approaches are possible. While artificial intelligenceis favoured by some, we think that a less 'heavy' approach can be more cost and time efficient. The casewe have chosen to exemplify our approach concerns architectural heritage. To match supply and demandwhile at the same time respecting the constraints imposed by cultural heritage, it is necessary to bringthem together and to effectuate feasibility studies in the shortest possible time. The feasibility study shouldbe served by tools allowing the various partners to communicate on the level of the match between them, translated in terms of spatial organisation and building constraints. In the past years, our designmorphology group has developed and tested a graphic-based reordering tool which has been applied to large governmental buildings, both existing and new. The same tool can be used for weighted objectives ranking and evaluation, to have a synthetic view of the combined basic preferences and differences of the involved parties as for example in a jury wise evaluation and ranking of alternative proposals. The proposed tool is the electronic and graphic version of the data and association matrices, which have been for a long time recommended for use in the preliminary phases of design. But as long as these instruments could only be drawn and redrawn on paper they were much too ineffectual and found little real application. The developed tool is connected by sub-routines to a computer aided design package, within which the spatial patterns are translated into plans and attached data bases. The matching takes place in a number of steps. The first is to describe the organisation (the demanding party) as functional units which can be made corresponding with spatial units. The prescription of spatial needs can take place in both quantitative and qualitative manners. The Matchmaker tools offer the possibility of interactive clustering of spatial needs. Another step, which can be taken concurrently, is to describe the monument in spatial units and distance relationships. The input can be generated directly within the matrix, but it is much easier, more self evident and realistic to generate this automatically from the draughted plan. The following step is the input of constraints originating from heritage preservation objectives, expressed in levels of authorised intervention. Again, the Matchmaker tools offer here the possibility of visual clustering of spatial units, their relationships and associated properties. In the next step, the matching takes place. In this step the actual positions, properties and constraints of existing spaces in the monument are compared (and visualised by discrepancies views) to the optimised and clustered spatial needs of the end user. In the following phase, the feasibility in terms of space, building fabric and costs can be appraised. Once a compromise has been attained, preliminary proposals can be designed and laid down in terms of drawings. The spatialdesigns can then again be translated into matrix views and evaluated.

title Sketch-Trigger: A Specification for a Form Generator and Design Analysis Toolbox for Architectural Sketching
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary In order to develop design and decision support techniques in the early sketch design phases, weshould (1) experience and (2) observe real behaviour in practice, (3) transform observations intoideas for improvement, (4) develop behaviour models to explain the sketch design activities and(5) to evaluate between the proposals, (6) decide between the alternatives, (7) implement theselected option in a supporting tool. Our paper reports about the results of step 3 in particular inthe first phase of a Ph D project, started this year. Our main objective is to amplify the effects ofthe sketch as a very effective instrument to generate original forms and to stimulate the mind to discover new shapes and meanings in the roughly sketched patterns. Instead of considering the sketch only as a representation of what the designer has in mind as is usually assumed in CAD systems, we see sketching as form activation. Thus, we want also to offer triggering images to spark off the imagination of the designer while generating images which are practically impossibleto create by hand and certainly not at short notice. The main improvement proposed is the use of an evolutionary form breeding system: one or more sketched parent images (either ready-made'partis' or basic schemes drafted by the designer) presented in the centre of the screen, will generate surrounding mutated children as defined at random but constrained by default or customization of the available transformations. By selecting one or more children a next generation will be produced in the same way. At all times the designer can introduce or reduce constraints. To complete the usually offered 'classical' symmetrical, spatial and logical operations,we want to introduce dis-functional operations like dislocation, explosion, deformation, anti-logic etc, in short all kinds of antagonistic operations, among them the transformations applied indeconstructionist and post-modern design. Our expectation is that these operations will correspond roughly to the 'move' pertaining to a design entity as the operational unit most appropriate for design behaviour research, in particular the analysis of the chunking and parsing behaviour of the designer. The applicability of the 'move' approach has been shown experimentally by Habraken and others. Goldschmidt has abandoned the usual typology approach of protocolanalysis based on moves and concentrated on the linking of moves, but has been hampered by the lack of a good representational instrument. This brings us to the representation of moves and linkages as a research instrument. The 'linkograph' approach as proposed by Goldschmidt is a first step towards a graphical representation of the designers associative reasoning mode, necessary for tracking the heuristics of designers at the most basic level, but its practical implementation remained as yet incredibly laborious. What is proposed here is an instrument and approach which makes such registration and analysis possible within a structured software environment.

summary This paper describes a continuing research project aimed at the development of a prototype information system to represent and manipulate models of urban settlements. This inter-disciplinaryproject involves researchers and teachers in the fields of urban design, photogrammetry and CAD. Based upon the requirements identified by the urban design team, the photogrammetry teamused aerial imagery to produce accurate digital models of various features of urban settlements. The models comprise natural features like terrain data, water and vegetation systems, and man made features like transportation networks, land parcels, and built-up volumes. These data are represented in the three dimensions, and they are further linked with nongraphic attributes stored in an external database schemata. The architecture of the system under development has been described previously. In this paper, we focus on the generation of thematic abstractions. The working hypothesis for our current work is that (i) to enable reliable decision-making in urbandesign contexts, we require digital models that are complete and accurate at a certain degree of resolution, and (ii) during various stages in the decision-making, we need useful abstractionswhich encode only the salient information and no more. In more specific terms, we are interested in finding computational means to automatically generate schematic generalizations of data that succinctly represent some information without recomputing or displaying all the vectrs and other details. In this papar we present some of the strategies that we employ to support such operations in our system and also present graphic examples that demonstrate the potential andlimitations of our approach.
