title	Computer-aided design systems for the 21st century: some design guidelines
source	Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary	This paper proposes nine design principles for a new generation of computer-aided design (CAD) systems that actively support the decision making and problem solving activities of environmental design. Foremost among these are: a meaningful internal object-based representation of the artifact being designed within its environmental context; a collaborative problem solving paradigm in which the human designer and the computer form a complementary partnership; and, the notion of decision-support tools rather than predefined solutions. Two prototype computer-aided design systems implemented by the CAD Research Center that embody most of these concepts are described. ICADS (Intelligent Computer-Aided Design System) incorporates multiple expert agents in domains such as natural and artificial lighting, noise control, structural system selection, climatic determinants, and energy conservation. Given a particular building design context, the agents in ICADS draw upon their own expertise and several knowledgebases as they monitor the actions of the human designer and collaborate opportunistically. KOALA (Knowledge-Based Object-Agent Collaboration) builds on the multi-agent concepts embodied in ICADS by the addition of two kinds of agents. Mentor agents represent the interests of selected objects within the ontology of the design environment. In the implemented KOALA system building spaces are represented by agents capable of collaborating with each other, with domain agents for the provision of expert services, and with the human designer. Facilitator agents listen in on the communications among mentor agents to detect conflicts and moderate arguments. While both of these prototype systems are limited in scope by focussing on the earliest design stages and restricted in their understanding of the inherent complexity of a design state, they nevertheless promise a paradigm shift in computer-aided design.

title	On the Translation of Design Data into Design Form in Evolutionary Design
source	International Conference on Generative Art
summary	The marriage of advanced computational methods and new manufacturing technologies give rise to new paradigms in design process and execution. Specifically, the research concerns itself with the application of Generative and Evolutionary computation to the production of mass-customized products and building components. The work is based on the premise that CAD-CAM should evolve into a dynamic, intelligent, multi-user environment that encourages creativity and actively supports the evolution of individual, mass-customized designs that exhibit common features. The concept of Parametric Design is well established, and chiefly concerns itself with generating design sets that exists within the boundaries of pre-set parametric values. Evolutionary Design extends the notion of parametric control by using rule-based generative algorithms to evolve common families of individual design solutions. These can be optimized according to particular criteria, or can form a wide variety of hierarchically related design solutions, while supporting design intuition. The integration of Evolutionary Design with CAD-CAM, in particular the areas of flexible manufacturing and mass-customization, creates a unique scenario which exploits the full power of both approaches to create a new design-process paradigm that can generate limitless possibilities in a non-deterministic manner within a variable search-space of possible solutions.This paper concerns itself with the technical and philosophical aspects of the codification, generation and translation of data within the evolutionary-parametric design process. The efficiency and relevance of different methods for treating design data form the most fundamental aspect within the realm of CAD/CAM and are crucial to the successful implementation of Evolutionary Design mechanisms. This begins at the level of seeding and progresses through the entire evolutionary sequence, including the codification for evaluation criteria. Furthermore, the integration of digital design mechanisms with CAM and CNC technologies requires further translation of data into manufacturable formats. This paper examines different methods available to system designers and discussed their effect on new paradigms of digital design methods.

title	Perception Aspects in Underground Spaces using Intelligent Knowledge Modeling
source	Delft University of Technology
summary	The intensification, combination and transformation are main strategies for future spatial development of the Netherlands, which are stated in the Fifth Bill regarding Spatial Planning. These strategies indicate that in the future, space should be utilized in a more compact and more efficient way requiring, at the same time, re-evaluation of the existing built environment and finding ways to improve it. In this context, the concept of multiple space usage is accentuated, which would focus on intensive 4-dimensional spatial exploration. The underground space is acknowledged as an important part of multiple space usage. In the document 'Spatial Exploration 2000', the underground space is recognized by policy makers as an important new 'frontier' that could provide significant contribution to future spatial requirements.In a relatively short period, the underground space became an important research area. Although among specialists there is appreciation of what underground space could provide for densely populated urban areas, there are still reserved feelings by the public, which mostly relate to the poor quality of these spaces. Many realized underground projects, namely subways, resulted in poor user satisfaction. Today, there is still a significant knowledge gap related to perception of underground space. There is also a lack of detailed documentation on actual applications of the theories, followed by research results and applied techniques. This is the case in different areas of architectural design, but for underground spaces perhaps most evident due to their infancv role in general architectural practice. In order to create better designs, diverse aspects, which are very often of qualitative nature, should be considered in perspective with the final goal to improve quality and image of underground space. In the architectural design process, one has to establish certain relations among design information in advance, to make design backed by sound rationale. The main difficulty at this point is that such relationships may not be determined due to various reasons. One example may be the vagueness of the architectural design data due to linguistic qualities in them. Another, may be vaguely defined design qualities. In this work, the problem was not only the initial fuzziness of the information but also the desired relevancy determination among all pieces of information given. Presently, to determine the existence of such relevancy is more or less a matter of architectural subjective judgement rather than systematic, non-subjective decision-making based on an existing design. This implies that the invocation of certain tools dealing with fuzzy information is essential for enhanced design decisions. Efficient methods and tools to deal with qualitative, soft data are scarce, especially in the architectural domain. Traditionally well established methods, such as statistical analysis, have been used mainly for data analysis focused on similar types to the present research. These methods mainly fall into a category of pattern recognition. Statistical regression methods are the most common approaches towards this goal. One essential drawback of this method is the inability of dealing efficiently with non-linear data. With statistical analysis, the linear relationships are established by regression analysis where dealing with non-linearity is mostly evaded. Concerning the presence of multi-dimensional data sets, it is evident that the assumption of linear relationships among all pieces of information would be a gross approximation, which one has no basis to assume. A starting point in this research was that there maybe both linearity and non-linearity present in the data and therefore the appropriate methods should be used in order to deal with that non-linearity. Therefore, some other commensurate methods were adopted for knowledge modeling. In that respect, soft computing techniques proved to match the quality of the multi-dimensional data-set subject to analysis, which is deemed to be 'soft'. There is yet another reason why soft-computing techniques were applied, which is related to the automation of knowledge modeling. In this respect, traditional models such as Decision Support Systems and Expert Systems have drawbacks. One important drawback is that the development of these systems is a time-consuming process. The programming part, in which various deliberations are required to form a consistent if-then rule knowledge based system, is also a time-consuming activity. For these reasons, the methods and tools from other disciplines, which also deal with soft data, should be integrated into architectural design. With fuzzy logic, the imprecision of data can be dealt with in a similar way to how humans do it. Artificial neural networks are deemed to some extent to model the human brain, and simulate its functions in the form of parallel information processing. They are considered important components of Artificial Intelligence (Al). With neural networks, it is possible to learn from examples, or more precisely to learn from input-output data samples. The combination of the neural and fuzzy approach proved to be a powerful combination for dealing with qualitative data. The problem of automated knowledge modeling is efficiently solved by employment of machine learning techniques. Here, the expertise of prof. dr. Ozer Ciftcioglu in the field of soft computing was crucial for tool development. By combining knowledge from two different disciplines a unique tool could be developed that would enable intelligent modeling of soft data needed for support of the building design process. In this respect, this research is a starting point in that direction. It is multidisciplinary and on the cutting edge between the field of Architecture and the field of Artificial Intelligence. From the architectural viewpoint, the perception of space is considered through relationship between a human being and a built environment. Techniques from the field of Artificial Intelligence are employed to model that relationship. Such an efficient combination of two disciplines makes it possible to extend our knowledge boundaries in the field of architecture and improve design quality. With additional techniques, meta know/edge, or in other words "knowledge about knowledge", can be created. Such techniques involve sensitivity analysis, which determines the amount of dependency of the output of a model (comfort and public safety) on the information fed into the model (input). Another technique is functional relationship modeling between aspects, which is derivation of dependency of a design parameter as a function of user's perceptions. With this technique, it is possible to determine functional relationships between dependent and independent variables. This thesis is a contribution to better understanding of users' perception of underground space, through the prism of public safety and comfort, which was achieved by means of intelligent knowledge modeling. In this respect, this thesis demonstrated an application of ICT (Information and Communication Technology) as a partner in the building design process by employing advanced modeling techniques. The method explained throughout this work is very generic and is possible to apply to not only different areas of architectural design, but also to other domains that involve qualitative data.

title	AUGMENTED REALITY MEETING TABLE: A NOVEL MULTI-USER INTERFACE FOR ARCHITECTURAL DESIGN
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. 213-231
summary	Immersive virtual environments have received widespread attention as providing possible replacements for the media and systems that designers traditionally use, as well as, more generally, in providing support for collaborative work. Relatively little attention has been given to date however to the problem of how to merge immersive virtual environments into real world work settings, and so to add to the media at the disposal of the designer and the design team, rather than to replace it. In this paper we report on a research project in which optical see-through augmented reality displays have been developed together with prototype decision support software for architectural and urban design. We suggest that a critical characteristic of multi user augmented reality is its ability to generate visualisations from a first person perspective in which the scale of rendition of the design model follows many of the conventions that designers are used to. Different scales of model appear to allow designers to focus on different aspects of the design under consideration. Augmenting the scene with simulations of pedestrian movement appears to assist both in scale recognition, and in moving from a first person to a third person understanding of the design. This research project is funded by the European Commission IST program (IST-2000-28559).

title	Virtual situation rooms: connecting people across enterprises for supply-chain agility
source	Computer-Aided Design, Vol. 32 (2) (2000) pp. 109-117
summary	Agility and time-based manufacturing are critical success factors for today's manufacturing enterprise. To be competitive, enterprises must integrate their supply chains moreeffectively and forge close memberships with customers and suppliers more quickly. Consequently, technologies must be developed that enable enterprises to respond toconsumer demand more quickly, integrate with suppliers more effectively, adapt to market variations more efficiently and evolve product designs with manufacturing practicesmore seamlessly. The mission of the Extended-Enterprise Coalition for Integrated Collaborative Manufacturing Systems coalition is to research, develop, and demonstratetechnologies to enable the integration of manufacturing applications in a multi-company supply chain planning and execution environment. We believe real-time andasynchronous collaboration technology will play a critical role in allowing manufacturers to increase their supply chain agility. We are realizing our efforts through our VirtualSituation Room (VSR) technology. The primary goal of the VSR technology is to enhance current ad-hoc, limited methods and mechanisms for spontaneous, real-timecommunication using feature-rich, industry standards-based building blocks and network protocols. VSR technology is being designed to find and engage quickly all relevantmembers of a problem solving team supported by highly interactive, conversational access to information and control and enabled by business processes, security policies andtechnologies, intelligence, and integration tools.

summary	In this paper we discuss the basis for the design of an Intelligent Design Assistants system, as for the development and application of an intelligent agent for design, predict and evaluate fenestrations. Its main goal is to answer our worries about the possibility of the implementation of the Partnership Paradigm through the development of one Intelligent Design Assistant. The paper deals from the difficulties of defining what design is, through its two main Paradigms, their instrumentation in CAAD systems, definition and explanation of the Partnership Paradigm, as proposed by Swerdloff y Kalay, agents approach, to the Intelligent Design Assistants system, in special one Assistant for Designing fenestrations. The paper finishes with the author’s vision on what the future on the Architecture profession will be in a world of Intelligent Design Assistants.

title	Conceptual design: issues and challenges
source	Computer-Aided Design, Vol. 32 (14) (2000) pp. 849-850
summary	Decisions made during conceptual design have significant influence on the cost, performance, reliability, safety and environmental impact of a product. It has been estimated that design decisions account for more than 75% of final product costs. It is, therefore, vital that designers have access to the right tools to support such design activities. In the early 1980s, researchers began to realize the impact of design decisions on downstream activities. As a result, different methodologies such as design for assembly, design for manufacturing and concurrent engineering, have been proposed. Software tools that implement these methodologies have also been developed. However, most of these tools are only applicable in the detailed design phase. Yet, even the highest standard of detailed design cannot compensate for a poor design concept formulated at the conceptual design phase. In spite of this, few CAD tools have been developed to support conceptual design activities. This is because knowledge of the design requirements and constraints during this early phase of a product's life cycle is usually imprecise and incomplete, making it difficult to utilize computer-based systems or prototypes. However, recent advances in fields such as fuzzy logic, computational geometry, constraints programming and so on have now made it possible for researchers to tackle some of the challenging issues in dealing with conceptual design activities. In this special issue, we have gathered together discussions on various aspects of conceptual design phase: from the capturing of the designer's intent, to modelling design constraints and solving them in an efficient manner, to verifying the correctness of the design.

title	Building product information search by images
source	Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary	Building product information is required during the architectural design and technical design. The common access to the technical information system is the multi-criteria search mode. This search mode is adapted to the situation where an architect has a precise demand of information. But most of the time, the architect looks for ideas and wants to obtain many illustrations of product uses. Therefore, the system has to propose another search mode adapted to the situation where the demand is still fuzzy. Considering that the architect has the capacity to think with image and that an image can generate easily ideas, then a search by images seems to be suitable to the situation where an architect looks for ideas. The web is an inexhaustible resource of images we can exploit to provision an image database on a specific area. The system we propose allows making building product information search with images extracted from the web. This article presents the method used to extract images from web sites of French building product companies and how these images are used in an interactive and progressive image retrieval process.

title	Mass-Customization in Design Using Evolutionary and Parametric Methods
doi	https://doi.org/10.52842/conf.acadia.2000.239
source	Eternity, Infinity and Virtuality in Architecture [Proceedings of the 22nd Annual Conference of the Association for Computer-Aided Design in Architecture / 1-880250-09-8] Washington D.C. 19-22 October 2000, pp. 239-244
summary	This paper describes a project within the authors’ 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-customized designs which exhibit common features. The authors describe this idea by illustrating the implementation of a research project, which explores the notions of mass-customization in design by using evolutionary and parametric methods to generate families of simple objects, in our case a door handle. The project examines related approaches using both complex CAD/CAM packages (CADDS, CATIA) and a proprietary software tool for evolutionary design. The paper first gives a short historical and philosophical background to the work, then describes the technical and algorithmic requirements, and concludes with the implementations of the project.

title	Multi-objective design for space layout topology
source	Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary	A novel method to produce space layout topologies for architectural design is described. From the uniformly distributed design solutions in the solution space the corresponding design requirements are computed according to a given norm and metric function. The system is based on graph representation of the layout so that the desired relations between the pairs of nodes are considered to be independent variables of appropriate series of multivariable functions mapping the requirements into the solution space. The system so established is used as a knowledge-base for robust layout design where knowledge base having been established, the layout design requirements are introduced to the system as design constraints and the output is identified in the multidimensional solution space by means of interpolation. Since the smoothness of the interpolation is guaranteed, robust design layout, in the form of node locations, is obtained.

title	A CAD-based decision support system for the design stage of a construction project
source	Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary	Decisions made during the design process are multi-dimensional, combining together factors which range from the highly subjective to the perfectly objective. These decisions are made by many, often non co-located, actors belonging to different disciplines. Moreover, there is a high risk for misunderstandings, inappropriate changes, and decisions, which are not notified to all interested parties. The ADS project (Advanced Decision Support for Construction Design) builds on the results of the earlier COMMIT project to provide an information management system, which addresses these problems. It defines mechanisms to handle the proactive management of information to support decision-making in collaborative projects. Different aspects of the COMMIT system have already been widely published, and the team is now applying the results in the context of construction design. These are referenced in the present paper, which gives an overview of the results of the COMMIT project and discusses some of the issue involved in applying them to the design process in conjunction with an advanced CAD tool.

title	Enhanced Boundary Representation: A Lingua Franca for Computer-Based Building Performance Simulation?
doi	https://doi.org/10.52842/conf.acadia.2000.012
source	ACADIA Quarterly, vol. 19, no. 4, pp. 12-14
summary	With the realistic visual representation of buildings on the computer having reached maturity, the emphasis has now shifted to the performance simulation of buildings on the computer. The challenge of performance simulation in computer-based models of buildings lies in the integration of various simulation techniques that require different kinds of building representations. Traditional simulation techniques for luminous, acoustic and thermal environments require different building representations. Thepaper proposes that an enhanced boundary representation is a viable, common building representation format for performance simulation of illumination levels, acoustical parameters and thermal comfort, thereby providing a building representation format for multi-domain performancesimulation on the computer. Simulation techniques that have been developed for radiosity-based modeling of illumination in buildings, radiation-based modeling of sound propagation in spatial enclosures, and the modeling of thermal comfort based on mean radiant temperatures, point to a convergence of techniques. These techniques can all work based on an enhanced boundary or surface representation of buildings. The paper suggests that an enhanced boundary representation format, and integrated performance simulation techniques based on radiation, can together serve as a core model for developers of computer-aided design analysis systems.

title	The Computer Integrated Road Construction project
source	Automation in Construction 9 (5-6) (2000) pp. 447-461
summary	This paper is about the "Computer Integrated Road Construction" (CIRC) project, which is a Brite-EuRam III funded project, lasting 1997–1999, aiming at introducing a new generation of control and monitoring tools for road pavements construction. These new tools are designed to bring on the sites significant improvements by creating a digital link between design office and job site. The first part of the paper describes the background of the project, which gathers seven European partners from five different countries, and gives the objectives of the project, in general and for each of the two targeted products: one for the compactors (CIRCOM) and one for the asphalt pavers (CIRPAV). Then, the two prototypes are described, each of them being broken down into three main sub-systems: the ground sub-system (GSS), the on-board sub-system (OB) and the positioning sub-system (POS). The expected benefits for the different users are also presented and quantified. The central part of the paper is devoted to the main technical innovations that have been developed in the frame of the project: universal vector database for road equipment guidance, multi-machine functionalities of CIRCOM and the two positioning systems which are actually the technological keys of the systems. Finally, the state of progress of the developments of the two CIRC products and the first commercial success achieved in parallel are presented.

title	A catalogue of built forms, using a binary representation
source	Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary	A technique is described for the representation of a class of rectangular built forms. Each individual form is produced by applying a series of transformations to a single generic or ‘archetypal’ form, which is designed to take care of the broad constraints, on built space, of close-packing and the requirements for natural light and views. Parts of the archetype which are selected for inclusion in any particular built form are then designated by 1s, and parts which are suppressed by 0s. This makes it possible to assign a unique binary code to each different (undimensioned) built form produced from the archetype. Binary codes corresponding to all legitimate forms may then be arranged in ascending order, to create a comprehensive catalogue. The paper describes such a catalogue comprising forms with up to four courtyards, described by 22-digit binary strings. Metric values may be assigned to the various dimensions of each form, making it a matter of simple arithmetic to compute such attributes as volume, surface area, minimum site area or floor space index. From logical operations on the binary strings it is possible to identify a series of configurational characteristics of the corresponding forms, such as their overall plan shapes, the number of courtyards or the potential for symmetry. The catalogue may thus be searched for built forms fulfilling some set of specifications, for example total floor area, site size and certain desired shape attributes. Worked examples are illustrated from the design of multi-storey office buildings. Possible applications are suggested for this approach, in architectural science and the early strategic stages of architectural design.

title	Indecision in quest of design
source	Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary	Designers all start with a solution (Darke, 1984), with what is known (Rittel, 1969, 1970). Hans Menghol, Svein Gusrud and Peter Opvik did so with the chair in the 1970s. Not content with the knowledge of the chair, however, they walked backward to the ignorance of the question that has always elicited the solution of chair and asked themselves the improbable question, “What is a chair?” Their answer was the Balans chair. “Until the introduction of the Norwegian Balans (balance) chair, the multi-billion dollar international chair industry had been surprisingly homogeneous. This chair is the most radical of the twentieth century and probably since the invention of the chair-throne itself (Cranz 1998). Design theorists have tried to understand in a measurable way what is not measurable: the way that designers think. Rather than attempt to analyze something that cannot be taken apart, I attempt to illuminate methods for generating new knowledge through ways of seeing connections that are not logical, and in fact are sometimes ironic. Among the possibilities discussed in this dialogue are the methodological power of language in the form of metaphor, the power of the imagination in mind experiments, the power of mythological story telling, and the power of immeasurable intangibles in the generation of the new knowledge needed to design.

title	Interfaces for Virtual Environments; A Review Recent Developments and Potential Ways forward

summary	The physical and visual nature of the interface devices and media that enable the human agent to interact with a virtual world have evolved over the past few years. In this paper we consider the different lines of development that have taken place in the refinement of these interfaces and summarise what has been learned about the appropriate nature of the interface for such interaction. In terms of the physical aspects we report on the kind of devices that have been used to enable the human agent to operate within the computer generated environment. We point out the successes and failures in the systems that have been tried out in recent years. Likewise we consider the kinds of software generated interface that have been used to represent virtual worlds. Again, we review the efficacy of the environments that have been devised; the quality of the Cyberplace. Our aim is to be able to comment on the effectiveness of the systems that have been devised from a number of points of view. We consider the physical and software-based aids for navigation; the nature of the representation of architectural worlds; strengthening “groundedness”; the inclusion of “otherness”; and reinforcement of the idea of “presence”

summary	In this study, we proposed a concept of virtual and real-field construction management systems (VR-Coms), which is integrated with virtual construction simulation, planning, scheduling, and performance management systems to evaluate productivity and safety in virtual simulated and real-field constructions. And, we built up a computational environment to develop the VR-Coms. The VR-Coms offer supporting modules for learning and discovering solutions with objective to manage construction at right speed with improved humanware and constructability. The configuration of VR-Coms is described. This paper also shows an application of agent theory to construction management.

summary	Virtual Reality (VR), and Artificial Intelligence (AI) technology have become increasingly more common in all disciplines of modern life. These new technologies range from simple software assistants to sophisticated modeling of human behavior. In this research project, we are creating an AI agent environment that helps architects to identify user preferences through a Virtual Reality Interface. At the current stage of development, the research project has resulted in a VR application - MuseV2 that allows users to instantly modify an architectural design. The distinctive feature of this application is that a space is considered as a base for all user modifications and as a connection between all design elements. In this paper we provide some technical information about MuseV2. Presentation of a design through VR allows AI agents to observe user-induced modifications and to gather preference information. In addition to allowing for an individualized design, this information generalized across a sample of users should provide the basis for developing basic designs for particular market segments and predict the market potential of those designs. The system that we envision should not become an automated design tool, but an adviser and viewer for users, who have limited knowledge or no knowledge at all about CAD systems, and architectural design. This tool should help investors to assess preferences for new community housing in order to meet the needs of future inhabitants.

title	Measuring user satisfaction for design variations through virtual reality
source	Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary	This paper describes Virtual Reality as an environment to collect information about user satisfaction. Because Virtual Reality (VR) allows visualization with added interactivity, this form of representation has particular advantages when presenting new designs. The paper reports on the development of a VR system that supports architects to collect opinions about their design alternatives in terms of user preferences. An alternative to conjoint analysis, that uses statistical choice variations to estimate user preference functions, is developed. Artificial Intelligence (AI) Agent technology will be implemented to build a model for data collection, prediction, and learning processes.

title	Refurbishment of building services engineering systems under a collaborative design environment
source	Automation in Construction 9 (2) (2000) pp. 185-196
summary	In this paper hypermedia is suggested as a suitable paradigm to represent the design processes associated with a shopping center refurbishment project. In addition, by adopting a collaborative design model, the paper makes reference to such factors as synchronous vs. asynchronous and active vs. passive modeling. Concepts in complex problem solving are also explored such as the soft system methodology as well as the application of agent-based decision support systems. Identification of primary information elements and analysis of the relations between these elements indicates that the flow of design information may be readily represented in hypermedia which features nonlinear characteristics in organizing information. The justification of developing a hypermedia tool to cope with changing conditions of a complex design problem instead of providing a solution for a predetermined problem is also argued. The paper illustrates the complex nature of collaborative design process with reference to a case study associated with the building services systems design for a Hong Kong Housing Authority refurbishment project.
