title Defects Defined by Form Making Method for Improving Generative Design System
source International Conference on Generative Art
summary Evolutionary-based Generative Design System (GDS) is generally designed for industrial designers during the early stage of conceptual design. Although “additive” Rapid Prototyping (RP) methods are commonly applied for the physical realization, grown Surfaces Object (SO) created from these GDS still has room to be considered to a combined workable volume,especially for the more complex design. The inarticulate processes from GDS to Generative Production System (GPS) are linking up with different aspects and contexts as well as the conventional Computer-Aided Design (CAD)/RP integration, which has been conducted for along time. There are design constraints existing between 3D SO in industry design representation and feasible 3D production solution. Perception to object designing with knowledge is limited at SO forming by incomplete interpretations. Meanwhile, it is difficult to discern the problemsof incomplete object generation as hidden illegal design occurred from time to time because of the design constraints, despite the completion of the design representation. It has led to some of the invalidity of surface feature at the end. The reconstruction of the RP process ofthe SO pre-processing procedure can help to clarify these defects with thickness requirement in generative production. The aim of this paper is to verify an effective generative design strategy as a possibility ofimplementing method(s) or tool. They will be built within a surface-oriented GDS by mapping a valid object directly accepted by any RP system without any influence on generative object creating. Through the involvement of Form Making processes of RP from selected instants with their solid phenomena, evidences are used for defending this viewpoint.Throughout the process, generative design method and CAD method have been utilized for the creation of virtual form. The 3D printer and Fused Deposition Modeling (FDM) technology with “trial and error” method were employed in the RP processes.

title Function-to-form mapping: model, representation and applications in design synthesis
source Computer-Aided Design, Vol. 33 (10) (2001) pp. 699-719
summary Design of a new artifact begins with incomplete knowledge about the final product and the design evolves as it progresses from the conceptual design stage to a moredetailed design. In this paper, an effort has been made to give a structural framework, through a set of generic definitions, to product specification, functionalrepresentation, artifact representation, artifact behavior and tolerance representation. A design synthesis process has been proposed for evolution of a product from theproduct specification. The proposed design synthesis method is a mapping from the functional requirements to artifacts, with multi-stage constrained optimization duringstages of design evolution. Provisions have been kept to augment and/or modify the product specification and domain knowledge during stages of development to guidethe design process. The effectiveness of the proposed design process has been illustrated with a simple design example based on a sample artifact library. An overalldesign scheme has been presented.

title Some Phenomena of Spatial Characteristics of Cyberspace

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

title Non-Linear Postrationalisation: Architectural Values Emergence in a Teamwork Interpretation

summary The paper presents the outcomes of the experiment being conducted at the Faculty of Architecture in Bialystok, which derives form three main sources: a new course of architectural composition by computer modelling, developed and conducted in Bialystok postrationalisation as a formulation platform for new architectural values and theories, applied by e.g. Bernard Tschumi the idea of new values emergence resulting form a teamwork, when placed in an appropriate environment; It is assumed that the work performed first intuitively, can be later seriously interpreted, and to some extent rationalised, verbalised, described. With no doubt we can state, that in creative parts of architectural activities, very often decision are taken intuitively (form design). So this ‘procedure’ of postrationalisation of intuitively undertaken efforts and results seems to be very important –when trying to explain ideas. This kind of activity is also very important during the first years of architectural education. In case of this experiment, the students’ works from the course of architectural composition are taken as a base and subjects for interpretation, and values research. However, when at first, individual works are being interpreted by their authors, at the latter stage, the teams are to be formed. The aim of the teamwork is to present individual works, analyse them, find common value(s), and represent it (them) in an appropriate, creative way. The ideal environment to perform this work is hypertext based internet, because the non-linearity of team interpretations is unavoidable. On the other hand, the digital input data (computer models) is a very appropriate initial material to be used for hypermedia development. The experiment is to analyse the specific of the following: the self-influence of the group on the individual work ‘qualification’, mutual influence of the team members on their own work interpretation, the influence of the digital non-linear environment on the final outcome definition. The added value of hypertext in architectural groupwork digital performance shall be examined and described. A new value of individualised, though group based, non-linearity of expression will be presented and concluded.

title Can simulations in VE support architects in solving complex design problems?

summary Building design is facing development of industrialization of the production on the one hand and more complex 'One of a Kind' products on the other. This will be for rebuilding of a large stock of existing buildings and what can be left to new production. In both cases the results of the design process have to be solid to guarantee a successful product. In both cases an integrated and careful design process is absolutely crucial. The demands on the built environment make the systems of buildings more and more complex and have to be handled by a lot of different expertise. To avoid the 'Relay Race' of today the design teams of tomorrow must work much more integrated. To make integrated solutions, which means simultaneous constrains on all systems, the experts of different fields have to understand more of how all engaged systems relate and influence each other. Communication then consists of complex situations and processes that have to be understood and related to reality. In this aspect a multidimensional Virtual Environment interface has advantages and has been successfully used in design processes in other industries. In this paper the problems that have to be studied are for example Methodical, Conceptual, Technical and Process economical.

title Designers‚ Cognition in Traditional versus Digital Media during Conceptual Design
source Bilkent University Ankara Turkey
summary Designers depend on representations to externalize their design thoughts. External representations are usually in the form of sketches (referred to as traditional media) in architectural design during the conceptual design. There are also attempts to integrate the use of digital representations into the conceptual design in order to construct a digital design medium. This thesis aims at gaining an insight on designers’ cognitive processes while sketching in digital versus traditional media. The analysis of cognitive processes of designers based on their protocols is necessary to reveal their design behavior in both media. An experiment was designed employing six interior architects (at Bilkent University) solving an interior space planning problem by changing the design media they work with. In order to encode the design behavior, a coding scheme was utilized so that inspecting both the design activity and the responses to media transition was possible in terms of primitive cognitive actions of designers. The analyses of the coding scheme constituents, which are namely segmentation and cognitive action categories enabled a comparative study demonstrating the effect of the use of different media in conceptual design phase. The results depicted that traditional media had advantages over the digital media such as supporting perception of visual-spatial features, and organizational relations of the design, production of alternative solutions and better conception of the design problem. These results also emerged implications for the computer aid in architectural design to support the conceptual phase of the design process.

summary The architectural design business is marked by a progressive increase in operators all cooperating towards the realization of building structures and complex infrastructures (Jenckes, 1997). This type of design implies the simultaneous activity of specialists in different fields, often working a considerable distance apart, on increasingly distributed design studies. Collaborative Architectural Design comprises a vast field of studies that embraces also these sectors and problems. To mention but a few: communication among operators in the building and design sector; design process system logic architecture; conceptual structure of the building organism; building component representation; conflict identification and management; sharing of knowledge; and also, user interface; global evaluation of solutions adopted; IT definition of objects; inter-object communication (in the IT sense). The point of view of the research is that of the designers of the architectural artefact (Simon, 1996); its focus consists of the relations among the various design operators and among the latter and the information exchanged: the Building Objects. Its primary research goal is thus the conceptual structure of the building organism for the purpose of managing conflicts and developing possible methods of resolving them.

title SHARED SPACE’ AND ‘PUBLIC SPACE’ DIALECTICS IN COLLABORATIVE ARCHITECTURAL DESIGN.
source Proceedings of Collaborative Decision-Support Systems Focus Symposium, 30th July, 2002; under the auspices of InterSymp-2002, 14° International Conference on Systems Research, Informatics and Cybernetics, 2002, Baden-Baden, pg. 27-44.
summary The present paper describes on-going research on Collaborative Design. The proposed model, the resulting system and its implementation refer mainly to architectural and building design in the modes and forms in which it is carried on in advanced design firms. The model may actually be used effectively also in other environments. The research simultaneously pursues an integrated model of the: a) structure of the networked architectural design process (operators, activities, phases and resources); b) required knowledge (distributed and functional to the operators and the process phases). The article focuses on the first aspect of the model: the relationship that exists among the various ‘actors’ in the design process (according to the STEP-ISO definition, Wix, 1997) during the various stages of its development (McKinney and Fischer, 1998). In Collaborative Design support systems this aspect touches on a number of different problems: database structure, homogeneity of the knowledge bases, the creation of knowledge bases (Galle, 1995), the representation of the IT datum (Carrara et al., 1994; Pohl and Myers, 1994; Papamichael et al., 1996; Rosenmann and Gero, 1996; Eastman et al., 1997; Eastman, 1998; Kim, et al., 1997; Kavakli, 2001). Decision-making support and the relationship between ‘private’ design space (involving the decisions of the individual design team) and the ‘shared’ design space (involving the decisions of all the design teams, Zang and Norman, 1994) are the specific topic of the present article.

Decisions taken in the ‘private design space’ of the design team or ‘actor’ are closely related to the type of support that can be provided by a Collaborative Design system: automatic checks performed by activating procedures and methods, reporting of 'local' conflicts, methods and knowledge for the resolution of ‘local’ conflicts, creation of new IT objects/ building components, who the objects must refer to (the ‘owner’), 'situated' aspects (Gero and Reffat, 2001) of the IT objects/building components.

Decisions taken in the ‘shared design space’ involve aspects that are typical of networked design and that are partially present in the ‘private’ design space. Cross-checking, reporting of ‘global’ conflicts to all those concerned, even those who are unaware they are concerned, methods for their resolution, the modification of data structure and interface according to the actors interacting with it and the design phase, the definition of a 'dominus' for every IT object (i.e. the decision-maker, according to the design phase and the creation of the object). All this is made possible both by the model for representing the building (Carrara and Fioravanti, 2001), and by the type of IT representation of the individual building components, using the methods and techniques of Knowledge Engineering through a structured set of Knowledge Bases, Inference Engines and Databases. The aim is to develop suitable tools for supporting integrated Process/Product design activity by means of a effective and innovative representation of building entities (technical components, constraints, methods) in order to manage and resolve conflicts generated during the design activity.

summary Building activity in Germany is moving increasingly toward combined newbuild and renovation projects. Essential for effective computer-aided planning within an existing context is not only the use of on-site computer-aided measurement tools but also an integrative cooperation between the different disciplines involved via an information and communication system. Interdisciplinary cooperation needs to be tailored to the integrative aspects in renovation and revitalisation work. Economic factors determine the viability of an architectural project, and reliable costing information is vital. Existing IT-approaches to this problem are not yet sufficiently exploited. In ongoing research at our university (collaborative research center ”Materials and Structure in the Revitalisation of Buildings”) methods and techniques of revitalisation are being investigated. A special branch of the collaborative research center is investigating possibilities of computer-aided building measurement and communication platforms for professional disciplines (www.uni-weimar.de/sfb). The aim is to develop a general approach to the revitalisation of buildings. This paper discusses possible application areas of AR/VR techniques in the revitalisation of buildings from the point of view of the user and are based on the real project “Cooling factory Gera”. Based on the necessities of revitalisation projects, technical requirements are developed. The project is funded by the Deutsche Forschungsgesellschaft (DFG).

title Awareness Space in Distributed Social Networks
source Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 615-628
summary In the real work environment we are constantly aware of the presence and activity of others. We know when people are away from their desks, whether they are doing concentrated work, or whether they are available for interaction. We use this peripheral awareness of others to guide our interactions and social behaviour. However, when teams of workers are spatially separated we lose 'awareness' information and this severely inhibits interaction and information flow. The Theatre of Work (TOWER) aims to develop a virtual space to help create a sense of social awareness and presence to support distributed working. Presence, status and activity of other people are made visible in the theatre of work and allow one to build peripheral awareness of the current activity patterns of those who we do not share space with in reality. TOWER is developing a construction set to augment the workplace with synchronous as well as asynchronous awareness. Current, synchronous activity patterns and statuses are played out in a 3D virtual space through the use of symbolic acting. The environment itself however is automatically constructed on the basis of the organisation's information resources and is in effect an information space. Location of the symbolic actor in the environment can therefore represent the focus of that person's current activity. The environment itself evolves to reflect historic patterns of information use and exchange, and becomes an asynchronous representation of the past history of the organisation. A module that records specific episodes from the synchronous event cycle as a Docudrama forms an asynchronous information resource to give a history of team work and decision taking. The TOWER environment is displayed using a number of screen based and ambient display devices. Current status and activity events are supplied to the system using a range of sensors both in the real environment and in the information systems. The methodology has been established as a two-stage process. The 3D spatial environment will be automatically constructed or generated from some aspect of the pre-existing organisational structure or its information resources or usage patterns. The methodology must be extended to provide means for that structure to grow and evolve in the light of patterns of actual user behaviour in the TOWER space. We have developed a generative algorithm that uses a cell aggregation process to transcribe the information space into a 3d space. In stage 2 that space was analysed using space syntax methods (Hillier & Hanson, 1984; Hillier 1996) to allow the properties of permeability and intelligibility to be measured, and then these fed back into the generative algorithm. Finally, these same measures have been used to evaluate the spatialised behaviour that users of the TOWER space show, and will used to feed this back into the evolution of the space. The stage of transcription from information structure to 3d space through a generative algorithm is critical since it is this stage that allows neighbourhood relations to be created that are not present in the original information structure. It is these relations that could be expected to help increase social density.

title Ideas - The Embodiment of Ideas, and Drawing: An Experimental Investigation of Inventing
source J. S. Gero, B. Tversky and T. Purcell (eds), 2001, Visual and Spatial Reasoning in Design, II - Key Centre of Design Computing and Cognition, University of Sydney, Australia
summary The term visual reasoning, in cognitive psychology, oftenrefers to the use of visual spatial relations in making inferences aboutcorresponding conceptual relations. The conclusion is that external visualrepresentations have special properties, which can aid reasoning abouthigher order abstract concepts. The design literature is more specific andoften sees visual reasoning as synonymous with drawing, and considersthis a core activity in resolving design problems. The research to bereported examined visual reasoning and design, by investigating the rolethat drawing plays in the practicality and creativity of inventions. Themost striking finding was that using only mental imagery produced morecreative and practical inventions than the use of drawing and that this wasdependant on the area of expertise of the participants. This appears to runcounter to the views found in both the visual reasoning and designliterature regarding the effectiveness of visual representations anddrawing. This has implications for our understanding of both the visualreasoning and design thinking processes.

title Improving design processes through structured reflection : a domain-independent approach
source Eindhoven University of Technology
summary In the world of designing, three fields of attention can be recognised, namely design research, design practice, and design education. Gaps exist between these three fields. In this thesis about designing, the focus is on the gap between design research and design practice. Design practice includes many design disciplines and an increasing number of multidisciplinary teams. Main problems in design practice are the communication between designers with a different background and the integration and co-ordination of important aspects during a design process. By tackling these problems, the effectiveness and efficiency of design processes in practice can be improved. The study of similarities and differences between design processes in several design disciplines and the development of support for reflection on design processes are topics that can improve design practice and that deserve more attention in design research. The goal of my research is to decrease the gap between design research and design practice in order to improve design processes. Reflection on design processes can help designers to improve their design process, its results, and the designer’s proficiency: By reflecting explicitly on the current design situation and on the performed design activities, in a systematic way and on a regular basis, designers can plan next design activities that can be performed effectively and efficiently given the design goal at that moment. In this thesis, the combination of systematic and regular reflection is called structured reflection. To improve design processes in various design disciplines in practice, the study of similarities and differences between design processes in several disciplines can be useful. Similarities between design processes are the basis for domain-independent design knowledge (as distinguished from domain-specific design knowledge). To reach the goal of my research, I have chosen to combine, in a broad explorative study, the development of support for structured reflection on design processes and the development of domain-independent design knowledge. This thesis describes a domain-independent approach to improve design processes through structured reflection. My research process can be summarised as follows. I studied three design disciplines, namely architecture, mechanical engineering, and software engineering. To get input from design practice, I did qualitative empirical research: I performed twelve case studies in the three disciplines to inventory characteristics of design processes and I compared the cases for similarities and differences. The similarities, together with the results of a literature study, have been the basis for the development of domain-independent descriptive design knowledge. The developed descriptive knowledge, in turn, formed the basis for developing domain-independent prescriptive design knowledge. At the end of the project, I confronted all results with design practice to get feedback on the results in another empirical study and I performed a literature study to position the results in the design literature. My design philosophy and design frame are the descriptive results developed to answer the first research question, namely “How to describe design processes in a domain-independent way?”. My design philosophy is a set of domain-independent concepts and terms for describing a design process. The concepts and terms are based on an application of the general theory of state-transition systems to the context of designing; the concepts of state and state transition correspond to the main concepts of design situation and design activity in my design philosophy. The answer to the first research question given by the design philosophy is refined in a design frame: The design frame offers a means to structure the description of a design process in a domain-independent way. Major structuring concepts of the design frame are dimensions and subjects. I define three dimensions, namely level, perspective, and time. These dimensions define a three-dimensional space, called a positioning space, in which important aspects of design processes can be positioned. A positioning space must be defined for each subject, being the three parts of a design situation: the product being designed, the design process, and the design context. My design frame is a domain-independent structure formed by the combination of the three dimensions for each subject. My design method is the prescriptive result developed to answer the second research question, namely “How to support structured reflection on design processes in a domain-independent way?”. My design method is a domain-independent aid that offers designers support for reflecting on design processes in a structured way. Reflection on design processes is defined as an introspective contemplation on the designer’s perception of the design situation and on the remembered design activities. A reflection process is described as a process that consists of three steps that are called preparation, image forming, and conclusion drawing. The design method is based on two main concepts: The first concept is the systematic description and analysis of design situations and design activities by means of forms and checklists; only systematic support for the preparation step of a reflection process is developed. The second concept is the idea of design sessions, introduced to stimulate designers to reflect regularly during a design process. A design session is defined as a period of time during which one or more designers are working on a subtask of a certain design task, for example, one afternoon, a whole day, or a week. Both concepts are combined to support structured reflection on design processes. The complete design method consists of five steps for each design session, namely planning a design session, defining the subtask of the design session, reflecting at the beginning of a design session, designing during the core of a design session, and reflecting at the end of a design session. A prototype software tool, called ECHO, has been developed to explore the benefits of using a software system to facilitate the use of the design method. Together, the design philosophy and the design frame offer concepts, a vocabulary, and a structure to describe design processes in a domain-independent way. The design method is a first proposal of a method that supports structured reflection on design processes. My results are thus possible answers to the mentioned research questions and are starting points to improve the effectiveness and efficiency of design processes. Based on the feedback I collected, I am optimistic about the applicability of my results in design practice. By asking input from design practice and by developing results that are useful for design practice and that contribute to design research, I contribute to decrease the gap between design research and design practice. The most important recommendations for further research are to test all results extensively in design practice and to investigate how to apply the results in design education.

title Interactive Storytelling and Its Role in the Design Process

summary Projects of ever increasing complexity and size have incited the need for new and robust design methodologies and tools in an effort to manage complexity, lower costs, ascertain quality and reduce risk. Technology convergence through the growing availability of networked computers, rapid progress in Computer Aided Design (CAD) and information management have encouraged the undertaking of even more complex designs that demand high degrees of interaction, collaboration and the efficient sharing and dissemination of information. It is suggested that interactive storytelling and interactive design (Rafi and Karboulonis, 2001) techniques that use non-linear information mapping systems can be deployed to assist users as they navigate information that is structured to address localized needs as they arise. The design process is a collaborative effort that encompasses diverse knowledge disciplines and demands the management and utilization of available resources to satisfy the needs of a single or set of goals. It is thought that building industry specialists should work close together in an organised manner to solve design problems as they emerge and find alternatives when designs fall short. The design process involves the processing of dynamic and complex information, that can be anything from the amount of soil required to level lands - to the needs of specific lightings systems in operation theatres. Other important factors that affect the design process are related to costs and deadlines. This paper will demonstrate some of our early findings in several experiments to establish nonlinear storytelling. It will conclude with a recommendation for a plausible design of such a system based on experimental work that is currently being conducted and is reaching its final stages. The paper will lay the foundations of a possible path to implementation based on the concept of multi-path animation that is appropriate for structuring the design process as used in the building industry.

summary In Architecture, it is essential to design functional and topologically complicated 3D shapes (i.e. shapes with many holes, columns and handles). In this paper, we present a robust and interactive system for the design of functional and topologically complicated 3D shapes. Users of our system can easily change topology (i.e. they can create and delete holes and handles, connect and disconnect surfaces). Our system also provide smoothing operations (subdivision schemes) to create smooth surfaces. Moreover, the system provides automatic texture mapping during topology and smoothing operations. We also present new design approaches with the new modeling system. The new design approaches include blending surfaces, construction of crusts and opening holes on these crusts.

title Using a Spatial Microsimulation Decision Support System for Policy Scenario Analysis
source Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Recent Advances in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Kluwer Academic Publishers, ISBN: 1-4020-2408-8, p. 177-191
summary This paper discusses the potential of a spatial microsimulation-based decision support system for policy analysis. The system can be used to describe current conditions and issues in neighbourhoods, predict future trends in the composition and health of neighbourhoods and conduct modelling and predictive analysis to measure the likely impact of policy interventions at the local level. A large dynamic spatial micro-simulation model is being constructed for the population of Leeds (approximately 715,000 individuals) based on spatial microsimulation techniques in conjunction with a range of data, including 2001 Census data for Output Areas and sample data from the British Household Panel Survey. The project has three main aims as follows: (i) to develop a static microsimulation model to describe current conditions in Leeds; (ii) to enable the performance of ‘What if?’ analysis on a range of policy scenarios; and (iii) to develop a dynamic microsimulation model to predict future conditions in Leeds under different policy scenarios. The paper reports progress in meeting the above aims and outlines the associated difficulties and data issues. One of the significant advantages of the spatial microsimulation approach adopted by this project is that it enables the user to query any combination of variables that is deemed desirable for policy analysis. The paper will illustrate the software tool being developed in the context of this project that is capable of carrying out queries of this type and of mapping their results. The decision support tool is being developed to support policy-makers concerned with urban regeneration and neighbourhood renewal.

summary In 1997, the Research Institute of Faculty of Architecture and Design, University of Zulia, started the R&D project of a decision making support system for tourism planning. For this, GIS technologies have been used for geocodification and spatial analysis of all the tourism facilities and resources existing in Zulia State, studying this kind of socioeconomic development according to critical poverty problems that are typical of their population. This paper describes this geographic information system, with the application of accessibility analysis, areas of influence, and threedimensional studies through network analysisó three-dimensional analysis with ArcView GIS clients, ArcExplorer clients, and MapObjects clients, on an MS Windows NT client/server environment.

title Performance-based computational design via differential modeling and two-staged mapping
source Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 667-680
summary Computational performance-based building design support faces a conflict. It is important to provide building performance feed back to the designer as early as possible in the design process. But many aspects of building performance are significantly affected by the design of the building’s technical systems, which are typically configured in detail only in the later stages of design. The challenge is thus to find a method to use detailed simulation tools even during the early stages of design when values for many of the variables for the building’s technical sub-systems are not yet available. In this paper, we demonstrate how this problem can be partially solved by combining two levels of automation. The first level consists of differential building representation involving a number of domain (application-specific) object models that are derived from a shared object model automatically. The second level uses generative agents that create reference designs for the technical sub-systems of the building. To demonstrate the feasibility of the proposed approach, we use the building energy systems domain (heating, cooling, ventilation, and air-conditioning) as a case in point.

title Component-based architecture for online collaborative disaster relief mission planning environments
source CIDAC, Volume 3 Issue 2 May 2001
summary International disaster relief mission planning situations involve geographically dispersed participants working in a stressful environment towards a common goal. When a large-scale disaster occurs, issues such as search and rescue, survivor relocation and infrastructure rebuilding need to be addressed in a short amount of time. Several constraints exist in this environment such as cultural differences among the relief agencies and the need for flexibility to handle changes in the situation. These constraints lead ot the need for a complex collaboration system which includes support for meeting protocol enforcement, session logging, multiple device access and reliability during periods of highly unstable network conditions.   A component based collaboration infrastructure to support multi-device web-based collaboration sessions has been designed to address such requirements. The system components include a data repository, a collaboration manager and an information policy enforcer to address such constraints. The system can support communcation applications like simulation systems, GIS mapping and resouce management. To support such a wide range of applications and provide access to their data from various hardware devices, the design of the system developed in this research effort is applicatin and configuration neutral for greatest flexibility and applicability.

summary This research presents our progress of the second phase of City Administration System (CAS) (Rafi and Fazidin, 2001). It covers the terrain generation of Kuala Lumpur’s Central Business District about 30km x 30km at 1 meter resolution using the latest stereoscopic satellite data and survey data from Mapping Department of Malaysia’s Ministry of Science, Technology and Environment. CAS will be designed to have three main functions, namely: Flood Crisis Management (FCM), Architectural and Town Planning Management, and City Services and Administration. At a 1meter resolution, CAS will be able to predict, manage and visualise flash and major floods within the city with a very high degree of accuracy. It has been identified for CAS that there is a need to share information through collaborative environment in a more centralised manner that allows collective decisions, facilitates continuous updates, communicates effectively and permits the sharing of experiences and ideas.
