title	Evolutionary Design Tools for Mass-Customisation
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 152-156
summary	This paper describes an instance of the author’s ongoing research in the field of Generative Design. The work is based on the premise that computer-aided design (CAD) should evolve beyond its current limitation of one-way interaction, and become a dynamic, intelligent, multi-user environment that encourages creativity and actively supports the evolution of individual, mass-customised designs which exhibit common features. The understanding of fundamental shape-forming processes in nature inspires us to move beyond the existing CAD paradigms and re-examine the way we can benefit from the computers in design. We can use this knowledge to create a new generation of computer-based design tools which use evolutionary search algorithms to generate create a common family of individual designs optimised according to particular criteria, while supporting our design intuition. The author explores this idea by illustrating a research project between the Hong Kong Polytechnic University and Deakin University (Australia). The project implements a multi-user oriented design tool for evolutionary design, which was tailored to produce a simple object such as door handle. The paper first gives a short historical and philosophical to the work, then describes the technical and algorithmic requirements, and implementation of the system. It concludes by describing an experiment in which the system was used on a "live" test group of people to generate individual, mass-customised designs.

summary	Facilities Management (FM) can't be seen as a subject with a specific area of knowledge with exactly defined borders relative to other subjects. Analysing the economic aspects of FM leads to the realisation that building management is experiencing a process of increasing specialisation and professionalism. It is possible to define FM from a variety of different points of origin. One possible approach views FM as an integral solution for the administration of buildings, their commercial activities, and technical maintenance from an economic perspective, during the whole life of a building. FM covers all strategies in order to efficiently provide, adequately operate and adapt buildings, their contents and systems to changing organisational demands. The current practice of limited analysis of specific administrative aspects, e.g. maintenance, is replaced by consideration of all factors that affect costs. Since all costs can be directly traced to space, the perfect procedure requires that FM is practised during the *hole living-cycle, starting with the definition of the program of construction until the day of conversion or demolition. Through successful FM, the real estate can contribute decisively to the improvement of productivity and the quality of life.

summary	New technologies often reshape expectations, needs and Opportunities so as to develop strategic Plans for the implementation of Information Techniques in education and research. The widespread acceptance of the internet and more specifically the World Wide Web (WWW) has raised the awareness of educators to the potential for online education, virtual classrooms and even virtual universities. With the advent of computer mediated communication, especially the widespread adoption of the web as a publishing medium, educators see the advantages and potential of delivering educational material over the Internet. The Web offers an excellent medium for content delivery with full text, colour graphics support and hyperlinks. The Purpose of this paper is to present a model for the usage of web-based information technology in computer aided architectural design and engineering education. It involves the key features of a full educational system that is capable of offering the teacher and the student flexibility with which to approach their teaching and learning tasks in ways most appropriate to the architectural design and engineering education. Web-based educational system aims at creating quality in on-line educational materials taking collaboration, support, new skills, and, most of all, time. The paper concludes with a discussion of the benefits of such an education system suggesting directions for further work needed to improve the quality of architectural design and engineering education.

title	A database supporting evolutionary product model development for design
source	Automation in Construction 8 (3) (1999) pp. 305-323
summary	This paper presents the facilities in the EDM-2 product modeling and database language that support model evolution. It reviews the need for model evolution as a system and/or language requirement to support product modeling. Four types of model evolution are considered: (1) translation between distinct models, (2) deriving views from a central model, (3) modification of an existing model, and (4) model evolution based on writable views associated with each application. While the facilities described support all for types of evolution, the last type is emphasized. The language based modeling capabilities described in EDM-2 include: (a) mapping facilities for defining derivations and views within a single model or between different models; (b) procedural language capabilities supporting model addition, deletion and modification; (c) support for object instance migration so as to partition the set of class instances into multiple classes; (d) support for managing practical deletion of portions of a model; (e) explicit specification and automatic management of integrity between a building model and various views. The rationale and language features, and in some cases, the implementation strategy for the features, are presented.

title	XML for Flexibility an Extensibility of Design Information Models
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	The VR-DIS research programme aims at the development of a Virtual Reality – Design Information System. This is a design and decision support system for collaborative design that provides a VR interface for the interaction with both the geometric representation of a design and the non-geometric information concerning the design throughout the design process. The major part of the research programme focuses on early stages of design. The programme is carried out by a large number of researchers from a variety of disciplines in the domain of construction and architecture, including architectural design, building physics, structural design, construction management, etc.Management of design information is at the core of this design and decision support system. Much effort in the development of the system has been and still is dedicated to the underlying theory for information management and its implementation in an Application Programming Interface (API) that the various modules of the system use. The theory is based on a so-called Feature-based modelling approach and is described in the PhD thesis by [first author, 1999] and in [first author et al., 2000a]. This information modelling approach provides three major capabilities: (1) it allows for extensibility of conceptual schemas, which is used to enable a designer to define new typologies to model with; (2) it supports sharing of conceptual schemas, called type-libraries; and (3) it provides a high level of flexibility that offers the designer the opportunity to easily reuse design information and to model information constructs that are not foreseen in any existing typologies. The latter aspect involves the capability to expand information entities in a model with relationships and properties that are not typologically defined but applicable to a particular design situation only; this helps the designer to represent the actual design concepts more accurately.The functional design of the information modelling system is based on a three-layered framework. In the bottom layer, the actual design data is stored in so-called Feature Instances. The middle layer defines the typologies of these instances in so-called Feature Types. The top layer is called the meta-layer because it provides the class definitions for both the Types layer and the Instances layer; both Feature Types and Feature Instances are objects of the classes defined in the top layer. This top layer ensures that types can be defined on the fly and that instances can be created from these types, as well as expanded with non-typological properties and relationships while still conforming to the information structures laid out in the meta-layer.The VR-DIS system consists of a growing number of modules for different kinds of functionality in relation with the design task. These modules access the design information through the API that implements the meta-layer of the framework. This API has previously been implemented using an Object-Oriented Database (OODB), but this implementation had a number of disadvantages. The dependency of the OODB, a commercial software library, was considered the most problematic. Not only are licenses of the OODB library rather expensive, also the fact that this library is not common technology that can easily be shared among a wide range of applications, including existing applications, reduces its suitability for a system with the aforementioned specifications. In addition, the OODB approach required a relatively large effort to implement the desired functionality. It lacked adequate support to generate unique identifications for worldwide information sources that were understandable for human interpretation. This strongly limited the capabilities of the system to share conceptual schemas.The approach that is currently being implemented for the core of the VR-DIS system is based on eXtensible Markup Language (XML). Rather than implementing the meta-layer of the framework into classes of Feature Types and Feature Instances, this level of meta-definitions is provided in a document type definition (DTD). The DTD is complemented with a set of rules that are implemented into a parser API, based on the Document Object Model (DOM). The advantages of the XML approach for the modelling framework are immediate. Type-libraries distributed through Internet are now supported through the mechanisms of namespaces and XLink. The implementation of the API is no longer dependent of a particular database system. This provides much more flexibility in the implementation of the various modules of the VR-DIS system. Being based on the (supposed to become) standard of XML the implementation is much more versatile in its future usage, specifically in a distributed, Internet-based environment.These immediate advantages of the XML approach opened the door to a wide range of applications that are and will be developed on top of the VR-DIS core. Examples of these are the VR-based 3D sketching module [VR-DIS ref., 2000]; the VR-based information-modelling tool that allows the management and manipulation of information models for design in a VR environment [VR-DIS ref., 2000]; and a design-knowledge capturing module that is now under development [first author et al., 2000a and 2000b]. The latter module aims to assist the designer in the recognition and utilisation of existing and new typologies in a design situation. The replacement of the OODB implementation of the API by the XML implementation enables these modules to use distributed Feature databases through Internet, without many changes to their own code, and without the loss of the flexibility and extensibility of conceptual schemas that are implemented as part of the API. Research in the near future will result in Internet-based applications that support designers in the utilisation of distributed libraries of product-information, design-knowledge, case-bases, etc.The paper roughly follows the outline of the abstract, starting with an introduction to the VR-DIS project, its objectives, and the developed theory of the Feature-modelling framework that forms the core of it. It briefly discusses the necessity of schema evolution, flexibility and extensibility of conceptual schemas, and how these capabilities have been addressed in the framework. The major part of the paper describes how the previously mentioned aspects of the framework are implemented in the XML-based approach, providing details on the so-called meta-layer, its definition in the DTD, and the parser rules that complement it. The impact of the XML approach on the functionality of the VR-DIS modules and the system as a whole is demonstrated by a discussion of these modules and scenarios of their usage for design tasks. The paper is concluded with an overview of future work on the sharing of Internet-based design information and design knowledge.

title	Knowledge-Aided Design System for Intelligent Building Design
doi	https://doi.org/10.52842/conf.caadria.1999.305
source	CAADRIA '99 [Proceedings of The Fourth Conference on Computer Aided Architectural Design Research in Asia / ISBN 7-5439-1233-3] Shanghai (China) 5-7 May 1999, pp. 305-312
summary	In the age of information technology, architectural design problems become increasingly complex, the finding of optimal solutions has become more difficult and obscure. Computer-aided design techniques have been applied to solve these ill-structured design problems; however, most of these applications have been used for graphical automation. Design improvement in quality has not been achieved using traditional computer programs. To handle the critical design decision problems, design systems need to be structured based on theoretical problem solving models. This would enable the design system to handle the problem solving design knowledge as well as the various technological aspects and geometrical representations. A theoretical model, knowledge-aided design, is proposed. Knowledge-aided design is a conceptual and theoretical model based on fundamental principles of design. It provides a problem-solving environment and a procedure for knowledge-based computer-aided architectural design based on cognitive science and artificial intelligence techniques. As a partial implementation of the theoretical model, the development of knowledge-aided design system for intelligent building design is described.

title	Practical Support for Collaborative Design Involving Divided Interests
doi	https://doi.org/10.52842/conf.acadia.1999.126
source	Media and Design Process [ACADIA ‘99 / ISBN 1-880250-08-X] Salt Lake City 29-31 October 1999, pp. 126-137
summary	Collaboration is common in design, yet relatively little is known about the cognitive reasoning processes that occur during collaboration. This paper discusses collaborative design, emphasizing the elaboration and transformations of the problem search space, and the roles that unstructured verbal communication and graphic communication can play in these processes. The paper discusses a prototype system called the Immersive Discussion Tool (IDT) that supports asynchronous design. IDT allows collaborators to mark-up 3-D models over the Internet using a variety of tools, including diagrammatic marks, dynamic simulations and text annotations. IDT relies on VRML to view the models, with an extensive Java-based interface on the backend powering the interactive construction and playback of graphical annotations, the management of threaded discussions, and the management of file input/output. The development of this tool has revealed the difficulty of constructing complex marks in a virtual 3-D space, and the initial implementation of IDT suggests several strategies for solving these problems.

title	Use Case Driven Object Modeling with UML
source	A Practical Approach. Reading, MA: Addison-Wesley
summary	Combining some of today's best ideas about customer-driven object-oriented design, Use Case Driven Object Modeling with UML: A Practical Approach shows you how to use Unified Modeling Language (UML) in the real world, keeping with the author's proprietary software design process. The book begins with the genesis of the author's ICONIX Unified Object Modeling Approach, borrowing ideas and strategies from the "three amigos" who invented UML: Grady Booch, James Rumbaugh, and Ivar Jacobson. Throughout this text, the ICONIX method is used to model a stock trading system, with all the relevant UML diagrams, beginning with class definition and use cases. The author's approach to software relies heavily on customer requirements and use case scenarios for which he has a good deal of practical advice. He provides numerous hints for avoiding bogged-down diagrams. After preliminary design, he advocates drilling down into specifics with robustness diagrams, which trace how classes interact with one another. The most detailed design work comes next with sequence diagrams. Subsequent chapters offer tips on project management, implementation, and testing. Throughout this lively and intelligently organized book, the author presents numerous real-world tips (and Top 10 lists) that supply wisdom to his perspective on effective software design.

summary	The purpose of this research is to develop the CAFM system that supports the cost management related to the building maintenance. Furthermore, we examine the possible implementation of CAFM as the supporting tools of medium-long term planning and fiscal year planning of the Facility Management. The function of the building-maintenance-system-oriented-Life-Cycle Cost (LCC)-supporting CAFM system is the feasibility of reference with the relating information database, which are later used for comparative analysis. The following is a detailed explanation of its functions:1) Outlined data display function of the building parts and materials. 2) 3-dimensional CAD models management. 3) LCC display function of building parts and materials. 4) Search function. This system supports the development of an efficient maintenance planning, and an efficient undertaking of the maintenance program. The concrete effects are as follow, (1) Cost-efficient building maintenance planning. (2) Building value increased by appropriate budget planning of maintenance. (3) Processing load and time are shortened. (4) Human mistakes are decreased.

title	xWORLDS, the implementation of a three-dimensional collaborative sketch tool within the context of a third year design course
source	International Conference on Generative Art
summary	This work is the result of a postgraduate thesis done at the chair for Architecture and CAAD at the ETH in Zurich Switzerland. It proposes a prototype for a three-dimensional modelling tool in a networked environment. The work is composed of two distinct parts. (1) A modeling tool to create three-dimensional objects in an intuitive and interactive manner. (2) A database component to store and retrieve the objects. This modeller has been implemented for the first time in a design course, where students where using the modeller to sketch and interact within a large group to formulate aspects of their design. The Paper focuses on the modeller and on the experience from a one week workshop.1. Modelling Tool. The modeling tool operates in two different modes: (A). Composing cubic forms within a limited cubic space. (B). Deforming the composition of boxes by means of their interaction with a separate volume. For the composition of cubes, the user has to drag a cube with the mouse to continue placing cubes in space. Furthermore, he can move and delete the placed cubes. Simple and complex objects can be created this way, in an easy and intuitive manner. For the second mode, the forms are generated by intersecting a volume with an object created previously in the first mode. The volume can be scaled and moved. The part of the existing object located outside the volume remains unchanged, while the part that lies inside it is transformed in the same way as the volume. Complex forms can be created in this way with simple transformations. 2. Database Storage and Retrieval.The created objects can be stored in a database. Other users can access the objects stored in the database and continue working on them in the same modeling environment. There are two ways to interact with objects from the database. On one side it is possible to substitute the composition of cubes, and keep the distorted framestructure of the currently active object unchanged. On the other side it is possible to initiate a morphing process between the currently active framestructure and the framestructure of an object from the database. This process can be stopped at any time. It is always possible to switch back in the modeling modus and continue work on the object.3. Workshop at the the School of Design at the Hong Kong Polytechnic University.A Group of over 100 students were using the tool in a second year design course. The tool has been implemented as part of a workshop in the second half of the design studio. The workshop lasted for one week in which a collective dataset of over 1000 models has been created by the students. Afterwards, a possibility was given to the students to retrieve models from the database and to process them in different software packages or have them physically built by a 3D printer, and then continue working on the physical model.

title	Quantitative constructability analysis with a neuro-fuzzy knowledge-based multi-criterion decision support system
source	Automation in Construction 8 (5) (1999) pp. 553-565
summary	This paper presents a multi-criterion decision model for quantitative constructability analysis based on a neuro-fuzzy knowledge-based system. The traditional constructability definition is modified so that constructability can be quantified, measured, and improved. A multi-layer information aggregation network is proposed to incorporate the manager's subjective preference information. The constructor's technology management policy can be reflected in the constructability evaluation process based on technology implementation preferences. A systematic approach to constructability problem detection and constructability improvement is developed to improve technology performance. Two examples of constructability analyses for alternative concrete formwork technologies are given to demonstrate the functions of the proposed methodology.

title	From 2D Base Map To 3D City Model
source	UMDS '02 Proceedings, Prague (Czech Republic) 2-4 October 2002, I.17-I.28
summary	Since 1997 Helsinki City Survey Division has proceeded in experimenting and in developing the methods for converting and supplementing current digital 2D base maps in the scale 1:500 to a 3D city model. Actually since 1986 project areas have been produced in 3D for city planning and construction projects, but working with the whole map database started in 1997 because of customer demands and competitive 3D projects. 3D map database needs new data modelling and structures, map update processes need new working orders and the draftsmen need to learn a new profession; the 3D modeller. Laser-scanning and digital photogrammetry have been used in collecting 3D information on the map objects. During the years 1999-2000 laser-scanning experiments covering 45 km2 have been carried out utilizing the Swedish TopEye system. Simultaneous digital photography produces material for orto photo mosaics. These have been applied in mapping out dated map features and in vectorizing 3D buildings manually, semi automatically and automatically. In modelling we use TerraScan, TerraPhoto and TerraModeler sw, which are developed in Finland. The 3D city model project is at the same time partially a software development project. An accuracy and feasibility study was also completed and will be shortly presented. The three scales of 3D models are also presented in this paper. Some new 3D products and some usage of 3D city models in practice will be demonstrated in the actual presentation.

title	Virtual Reality and the Future of Publishing Archaeological Excavations: the multimedia publication of the prehistoric settlement on Tsoungiza at Ancient Nemea
source	New York: The Metropolitan Museum of Art
summary	The Nemea Valley Archaeological Project is a study of settlement and land use in a regional valley system in Greece extending from the Upper Paleolithic until the present. Active field research was conducted by four teams between 1981 and 1990. The first component was a regional archaeological survey. Second, and closely related to the first, was a social anthropological study of modern settlement and land use. Next was a team assigned to excavate the succession of prehistoric settlements of Ancient Nemea on Tsoungiza. Last, historical ecologists, a palynologist, and a geologist formed the environmental component of the research. As a result of advances in electronic publishing, plans for the final publication of the Nemea Valley Archaeological Project have evolved. Complete publication of the excavation of the prehistoric settlements of Ancient Nemea on Tsoungiza will appear in an interactive multimedia format on CD/DVD in Fall 2000. This project is planned to be the first electronic publication of the American School of Classical Studies at Athens. We have chosen to publish in electronic format because it will meet the needs and interests of a wider audience, including avocational archaeologists, advanced high school and college students, graduate students, and professional archaeologists. The multimedia format on CD/DVD will permit the inclusion of text, databases, color and black-and-white images, two and three-dimensional graphics, and videos. This publication is being developed in cooperation with Learning Sites, Inc., which specializes in interactive three-dimensional reconstructions of ancient worlds http://www.learningsites.com. The Nemea Valley Archaeological Project is particularly well prepared for the shift towards electronic publishing because the project's field records were designed for and entered in computer databases from the inception of the project. Attention to recording precise locational information for all excavated objects enables us to place reconstructions of objects in their reconstructed architectural settings. Three-dimensional images of architectural remains and associated features will appear both as excavated and as reconstructed. Viewers will be able to navigate these images through the use of virtual reality. Viewers will also be able to reference all original drawings, photographs, and descriptions of the reconstructed architecture and objects. In this way a large audience will be able to view architectural remains, artifacts, and information that are otherwise inaccessible.

source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 341-348
summary	This paper is about the development of a system that supports excavation surveys by use of a PC. The system consists of two sub-systems: One is the Onsite Support System (OSS). Other is the Excavation Data Shearing System (EDSS). OSS combines a database with a general purpose CAD system. When OSS is used, it is description by excavation site and information can be managed. EDSS combines a WEB server, a database, and a VRML server. When EDSS is used, information of relic can be shared on the Internet and discussed by researchers away from the site. It provides the users with a virtual reality experience of the excavation site. The experimental system has been used as a tool by practical excavation survey of Islam city ruins from the Middle Ages in the Arab Republic of Egypt. In this paper, the framework of the system is introduced. The authors verified the effectiveness of the system by participating in an excavation survey.

title	CAD Interfaces to the ARROW Manufactured Product Server
source	Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 1-11
summary	The UK national project ARROW (Advanced Reusable Reliable Objects Warehouse) provides an Internet based framework through which it is possible to identify any of a range of manufactured products meeting specific design criteria. This open framework (based upon the IAI's IFCs) provides a mechanism for users to search for products from any participating manufacturer or supplier based both on specific attributes of a product or on any of the textual descriptions of the product. The service returns the closest matching products and allows the user to navigate to related information including manufacturer, suppliers, CAD details, VR displays, installation instructions, certificates, health and safety information, promotional information, costings, etc. ARROW also provides a toolkit to enable manufacturers and suppliers to more easily map and publish their information in the format utilised by the ARROW system. As part of the ARROW project we have examined the ability to interface from a design tool through to ARROW to automatically retrieve information required by the tool. This paper describes the API developed to allow CAD and simulation tools to communicate directly with ARROW and identify appropriate manufactured information. The demonstration system enables CAD systems to identify the closest matching manufactured product to a designed product and replacing the designed product with the details supplied by the manufacturer for the manufactured product as well as pulling through product attributes utilised by the design application. This paper provides a description of the ARROW framework and issues faced in providing information based upon standards as well as containing information not currently modelled in public standards. The paper looks at issues of enabling manufacturers and suppliers to move from their current world-view of product information to a more data-rich and user accessible information repository (even though this enables a uniform comparison across a range of manufacturer's products). Finally the paper comments on the likely way forward for ARROW like systems in providing quality information to end users.

source	Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 245-262
summary	This paper introduces the concept of responsive design. It elaborates this concept as an approach to free form, adaptable, automated design applying physically based modeling techniques to the design process. Our approach attempts to bridge the gap between totally automated design and the free form brainstorming designers normally employ. We do this by automating the initial placement and sizing of design elements, with an interactive engine that appears alive and highly responsive. We present a method for applying these techniques to architectural space layout planning, and preliminary implementation details for a prototype system for developing rectangular, two-dimensional, single- story floor plans.

This methodology provides for a responsive design process, which allows a designer to easily make decisions whose consequences immediately propagate throughout the design. It combines the speed of automated design methods with the flexibility of manual design methods, while adding a highly interactive quality and a sense of collaboration with the design itself. In our approach, the designer creates a space plan by specifying and modifying graphic design objectives rather than by directly manipulating primitive geometry. The plan adapts to the changing state of objectives by applying the physics of motion to its elements. For design objectives to have an effect on a physically based space plan, they need to be able to apply appropriate forces to space plan elements. Space planning can be separated into two problems, determining topological properties and determining geometric properties. Design objectives can then be categorized as topological or geometric objectives. Topological objectives influence the location of individual spaces, affecting how one space relates to another. Geometric objectives influence the size and shape of space boundaries, affecting the dimensions of individual walls. This paper focuses on how to model a variety of design objectives for use in a physically based space planning system. We describe how topological objectives, such as adjacency and orientation, can be modeled to apply forces to space locations, and how geometric objectives, such as area, proportion, and alignment, can be modeled to apply forces to boundary edges.

title	GIS and the Investigation of the Environmental Heritage
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 219-224
summary	This paper presents an investigation on the architectural, natural, and cultural resources in the southern part of the state of Rio Grande do Sul, according to their historical or environmental value, identifying natural and cultural elements known and valued by local communities, regardless their experts’ classification. Resources are identified by means of geographical information systems, combined with field information. The area comprises the coastal strip and the plains located in the last frontier of the Brazilian territory and the water system dominated by the lakes Patos, Mangueira and Mirim. The inventory of the environmental, sociocultural and economic heritage provides the necessary insight for issuing new development alternatives based on local resources. Research activities will include: the ellaboration of general and thematic maps, based on LANDSAT 5 [bands 3, 4 and 5] images; aerial photographs; DSG/SGE and municipal maps [scales 1:250.000, 1:50.000 and 1:25.000]; field work for the recognition of remarkable elements; interviews with residents for assessing their perception of local values; and community and institutional statements. These informations, comprising the elements valued by their architectural and urban quality, historical relevance and environmental significance, organised in a database, will provide contextual guidelines for the planning of a tourist route. This route, delineated by the preservation, recovery and use of representative local resources, valued as expressions of a native culture, evocates the initial occupation of the gaúcho territory, and may be touristically promoted as "The Gaúcho’s Way". The project also aims at showing the potential offered by GIS for identifying and evaluating specific spatial characteristics.

title	Parametric Urbanism: Explorations in Generative Urban Design
source	International Conference on Generative Art
summary	This paper is the result of several years of research by the Authors into the new field of generative design, as applied to urbanism. Its purpose is to formulate a concept of parametric urbanism and data-driven urban design, and how it departs from existing concepts of urban analysis and resulting design methods. This paper first gives a definition and description of the notion of generative urban design, and its relevance to current the practice of architecture and global political, sociological and economic developments. The difference between dogmatic forms of urban design and new parametric research methods is explained, and the Authors argue the fundamental relevance of using examples of post-colonial large-scale projects. In support of this, the Authors explore the widening field of research into parametric and data-driven architecture and urban design and the history of rule-based and evolutionary design methodologies. The paper illustrates examples of successful research in the field of parametric and rule-based urban design, by the Authors as well as colleagues within the field. It surveys the Authors’ work done at the Architectural Association School of Architecture, at the Hong Kong Polytechnic University School of Design, as well as in practice and research-oriented consultancy. The projects illustrated support the thesis of parametric urbanism by showing its power and versatility when applied to very large-scale projects, in particular within the People’s Republic of China.

title	CoCoMa: a Collaborative Constraint Management System for the Collaborative Design

summary	Collaborative Design is a topic of particular current interest. Existing software allows a multiplicity of designers to work on the same project. What the software really allows is accessing to a part of the information of the project and changing it. Sometimes there is a hierarchical distribution of the power of change: some participants can be permitted to operate only on some limited layers of the object representation. In this case the changes they propose are to be accepted by a general manager of the design process. What is lacking in this kind of software is the explicit management on the reciprocal constraints posed by different participants. In this paper, an elementary Collaborative Design System is presented whose main concern is just the management of constraints. Each participant designs the part of the project of his/her concern instantiating objects comprised of geometric description, alphanumeric variables and constraints on both. Constraints can be of two types: absolute or defined by a range of allowed values of the constrained variable. A participant intervening later can accept the constraint, choosing a value in the permitted range, or decide to violate it. In this case the proposed violation is signalled to whom posed it.
