title	An Agent Framework for Recognition of Graphic Units in Drawings
source	Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 246-253
doi	https://doi.org/10.52842/conf.ecaade.2002.246
summary	Architects use graphic conventions in their drawings that have meaningful content to the design task. In previous work, such well-defined sets of graphic entities have been identified and defined. These sets are called graphic units. In this paper, we discuss how graphic unit recognition in drawings can take place using a multi-agent systems approach. This approach seems promising as singular agents may specialize in graphic unit-recognition, and multi-agent systems can address problems of ambiguity through negotiation mechanisms. We present an agent framework for this purpose, how it connects to the theory of graphic units, and how agents for recognizing graphic units are defined. The paper ends with a discussion of current findings and future work.

title	Artificial Design and Planning Support: Interactive Plan Generation andCoordination in Distributed Decision-Making
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings Avegoor, the Netherlands), 2002
summary	In this paper we discuss some basic issues pertaining to artificial plan design as a paradigm for architectural design and urban planning support. We present a model for artificial design generation based on learning control methodologies. Plan design is seen as a search for "coordinated" solutions (changes) that satisfy distributed domain requirements and views expressed by human or artificial agents. Learning control is used as a method to search for solutions that direct partial descriptionsproduced by agents, to follow their dynamically defined targets -despite conflicting requirements. The model is simulated for land use and layout plan design, involving decisions for the location and physical configuration of a hypothetical housing and retail development.

title	Can Doors and Windows Become Design Team Players?
source	Gero JS and Brazier FMT (eds) (2002) Agents in Design 2002. Key Centre of Design Computing and Cognition, University of Sydney, pp. 3-22
summary	In an architectural design session, suppose design objects such as doors, windows and rooms can look after themselves, what kind of recommendations would a designer get? What is the nature of a design environment that facilitates such interactions? Where would a design object acquire the knowledge that allows it to interact intelligently? How would such localized recommendations be aggregated to support global design decisions made by the designer? This paper investigates these questions through the notion of objects as agents in design.

title	Collaborative design of structures using intelligent agents
source	Automation in Construction 11 (1) (2002) pp. 89-103
summary	The construction industry has a long tradition of collaborative working between the members of a construction project team. At the design stage, this has traditionally been based on physical meetings between representatives of the principal design disciplines. To aid these meetings, the information and communications technologies that are currently available have been utilised. These have yielded some success but are hampered by the problems posed by the use of heterogeneous software tools and the lack of effective collaboration tools that are necessary to collapse the time and distance constraints, within which increasingly global design teams work. In particular, there are very few tools available to support distributed asynchronous collaboration. Distributed artificial intelligence, which is commonly implemented in the form of intelligent agents, offers considerable potential for the development of such tools. This paper examines some of the issues associated with the use of distributed artificial intelligence systems within the construction industry. It describes the potential for the use of agent technology in collaborative design and then goes on to present the key features of an agent-based system for the collaborative design of portal frame structures. An example is presented to demonstrate the working and benefits of the prototype system, which makes a significant contribution by allowing for peer to peer negotiation between the design agents.

title	Role of Trust in Automated Distributed Design
source	Gero JS and Brazier FMT (eds) (2002) Agents in Design 2002. Key Centre of Design Computing and Cognition, University of Sydney, pp. 71-83
summary	Distributed design involves many participants, each with their own expertise and goals. Information acquired from different participants may be valued differently in terms of accuracy and trustworthiness. Human participants in a distributed design setting often know whom they trust, and whose abilities they value. This knowledge is not often made explicit. It does, however, influence distributed design processes (i.e. the way in which members of a design team assess and incorporate each others' designs, objectives, evaluations). These trust relations need to be made explicit to be able to effectively support distributed design.

source	Gero JS and Brazier FMT (eds) (2002) Agents in Design 2002. Key Centre of Design Computing and Cognition, University of Sydney, pp. 249-256
summary	This paper presents the architecture of a two-layer A-design system. It then goes on to use that system in an example configuration design problem. Two-layer A-Design limits the bias of selecting the most commonly used components by having the ability to introduce new components.

title	Digital Design - Research and Practice
source	Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1 / Tainan (Taiwan) 13–15 October 2003, 464 p.
summary	The use of computers in the design of the built environment has reached a watershed. From peripheral devices in the design process, they have in recent years come to take centre stage. An illustration is immediately at hand. Just as the entries to the competition for the Chicago Tribune Tower in 1922 defined the state-of-the-art at the beginning of the twentieth century, we have a similar marker at the end of the century, the competition in 2002 to replace the World Trade Centre towers in Lower Manhattan offered us a range of architectural solutions that exemplified the state-of-the-art eighty years later, setting forth not only architectural statements but also illustrating clearly the importance of computers in the design of the built environment. In these entries of 2002, we can see that computers have not only become essential to the communication of design but in the investigation and generation of structure, form and composition. The papers in this book are the current state-of-the-art in computer-aided design as it stands in 2003. It is the tenth in a series sponsored by the CAAD Futures Foundation, compiled from papers presented at the biennial CAAD Futures Conferences. As a series, the publications have charted the steady progress in developing the theoretical and practical foundations for applications in design practice. This volume continues in that tradition; thus, this book is entitled Digital Design: Research and Practice. The papers are grouped into three major categories, reflecting thrusts of research and practice, namely: Data and information: its organisation, handling and access, including agents; Virtual worlds: their creation, application and interfaces; and Analysis and creation of form and fabric. The editors received 121 abstracts after the initial call for contributions. From these, 61 abstracts were selected for development into complete papers for further review. From these submissions, 39 papers were chosen for inclusion in this publication. These papers show that the field has evolved from theoretical and development concerns to questions of practice in the decade during which this conference has showcased leading work. Questions of theoretical nature remain as the boundaries of our field expand. As design projects have grasped the potentials of computer-aided design, so have they challenged the capabilities of the tools. Papers here address questions in geometric representation and manipulation (Chiu and Chiu; Kocaturk, Veltkamp and Tuncer), topics that may have been considered to be solved. As design practice becomes increasingly knowledge based, better ways of managing, manipulating and accessing the complex wealth of design information becomes more pressing, demanding continuing research in issues such as modelling (Yang; Wang; Zreik et al), data retrieval and querying (Hwang and Choi; Stouffs and Cumming; Zreik, Stouffs, Tuncer, Ozsariyildiz and Beheshti), new modes of perceiving data (Segers; Tan). Tools are needed to manage, mine and create information for creative work, such as agents (Liew and Gero; Smith; Caneparo and Robiglio; Ding et al) or to support design processes (Smith; Chase). Systems for the support and development of designs continue (Gero; Achten and Jessurun). As progress is made on some fronts, such as user interfaces, attention is again turned to previously research areas such as lighting (Jung, Gross and Do; Ng et al; Wittkopf; Chevier; Glaser, Do and Tai) or services (Garcia; Chen and Lin). In recent years the growth of connectivity has led to a rapid growth in collaborative experience and understanding of the opportunities and issues continues to mature (Jabi; Dave; Zamenopoulos and Alexiou). Increasing interest is given to implications in practice and education (Dave; Oxman; Caneparo, Grassi and Giretti). Topics new to this conference are in the area of design to production or manufacture (Fischer, Burry and Frazer; Shih). Three additional invited papers (Rekimoto; Liu; Kalay) provide clear indication that there is still room to develop new spatial concepts and computer augmented environments for design. In conclusion, we note that these papers represent a good record of the current state of the evolving research in the field of digital design.

title	Towards a multi-agent model for visualizing simulated user behavior to support the assessment of design performance
source	Automation in Construction 11 (2) (2002) pp. 135-145
summary	We introduce the outline of a multi-agent model that can be used for visualizing simulated user behavior to support the assessment of design performance. We will consider various performance indicators of building environments, which are related to user reaction to design decisions. This system may serve as a media tool in the design process for a better understanding of what the design will look like, especially for those cases where design or planning decisions will affect the behavior of individuals. The system is based on cellular automata and multi-agent simulation technology. The system simulates how agents move around in a particular 3D (or 2D) environment, in which space is represented as a lattice of cells. Agents represent objects or people with their own behavior, moving over the network. Each agent will be located in a simulated space, based on the cellular automata grid. Each iteration of the simulation is based on a parallel update of the agents conforming local rules. Agents positioned within an environment will need sensors to perceive their local neighborhood and some means with which to affect the environment. In this way, autonomous individuals and the interaction between them can be simulated by the system. As a result, designers can use the system to assess the likely consequences of their design decisions on user behavior. We think that the system provides a potentially valuable tool to support design and decision-making processes, related to user behavior in architecture and urban planning.

title	Distributed Agents for Morphologic and Behavioral Expression in Cellular Design Systems
source	Thresholds - Design, Research, Education and Practice, in the Space Between the Physical and the Virtual [Proceedings of the 2002 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-11-X] Pomona (California) 24-27 October 2002, pp. 111-121
doi	https://doi.org/10.52842/conf.acadia.2002.111
summary	After more than a century of domination by neo-Darwinian theory, biological thought is beginning to giveincreasing recognition to developmental theory. Amongst other reasons, this recent widening ofperspective is grounded on the incompleteness of the neo-Darwinian perspective in providing modelsfor the invention of novel forms or species and individual development. Evolutionary design theory hasdrawn much of its inspiration from evolutionary biology and consequently shows analogous flaws. Thispaper demonstrates an adoption of biological developmental theory to the field of design theory in orderto fill the corresponding gap. As natural developmental processes are based on the development ofcellular units, which form composite structures, this paper employs the cellular model as a means for thedevelopment of a corresponding design and construction theory. The discussion of this approachincludes possible linkages between morphologic and behavioral attributes of tissues with implicationsfor self-assembly, growth, healing and self-reproduction of man-made structures.

title	An Agent-Based System for Capturing and Indexing Software Design Meetings
source	Gero JS and Brazier FMT (eds) (2002) Agents in Design 2002. Key Centre of Design Computing and Cognition, University of Sydney, pp. 203-218
summary	We present an agent-based system for capturing and indexing software design meetings. During these meetings, designers design object-oriented software tools, including new agent-based technologies for the Intelligent Room, by sketching UML-type designs on a white-board. To capture the design meeting history, the Design Meeting Agent requests available audio, video, and screen capture services from the environment and uses them to capture the entire design meeting. However, finding a particular moment of the design history video and audio records can be cumbersome without a proper indexing scheme. To detect, index, and timestamp significant events in the design process, the Tahuti Agent, also started by the Design Meeting Agent, records, recognizes, and understands the UML-type sketches drawn during the meeting. These timestamps can be mapped to particular moments in the captured video and audio, aiding in the retrieval of the captured information. Metaglue, a multiagent system, provides the computational glue necessary to bind the distributed components of the system together. It also provides necessary tools for seamless multi-modal interaction between the varied agents and the users.

title	A Complex Systems Perspective on How Agents Can Support Collaborative Design
source	Gero JS and Brazier FMT (eds) (2002) Agents in Design 2002. Key Centre of Design Computing and Cognition, University of Sydney, pp. 95-111
summary	Almost all complex artifacts nowadays, including physical artifacts such as airplanes, as well as informational artifacts such as software, organizational designs, plans and schedules, are created via the interaction of many, sometimes thousands of participants, working on different elements of the design. This collaborative design process is typically expensive and time-consuming because strong interdependencies between design decisions make it difficult to converge on a single design that satisfies these dependencies and is acceptable to all participants. Complex systems research concerning the generic dynamics of distributed networks has much to offer to the understanding of this process. This paper describes some insights derived from this novel perspective.

doi	https://doi.org/10.52842/conf.caadria.2002.199
summary	Situated design agents require new types of memory. The design of a memory system for use in such a design agent, based on the notion of constructive memory is proposed. The specification of the memory system is derived from the architecture of a situated design agent. Cognitive studies of the human memory system provide the functional and behavioural characterization of the memory system.

title	A Knowledge Based Collaborative Design Environment
source	Gero JS and Brazier FMT (eds) (2002) Agents in Design 2002. Key Centre of Design Computing and Cognition, University of Sydney, pp. 233-246
summary	In this paper, we propose an agent based collaborative design environment in which human designers and software agents interact with each other, exchange design information and keep track of state information to assist with collaborative design. First of all, it presents a hierarchical multi-agent system architecture for integrating design and engineering tools, software agents and human specialists in an open environment. The hierarchical multi-agent system architecture offers a promising framework with their novel approaches for dynamically creating and managing design tasks in widely distributed and ever-changing design environments. Secondly, it introduces a collaborative design process model and the dynamic management approach for collaborative design process. Then, the structure of a design agent, its static knowledge and dynamic knowledge are introduced respectively. The knowledge based design approach provides a foundation for supporting reusable design activities. Finally, the cooperative design process is illustrated by a bicycle design example.

source	Gero JS and Brazier FMT (eds) (2002) Agents in Design 2002. Key Centre of Design Computing and Cognition, University of Sydney, pp. 23-38
summary	This paper presents a User-centred Virtual Architecture (UcVA) Agent, a kind of rational agent capable of representing a person in virtual worlds and designing virtual worlds based on current needs. The two major structural aspects of this agent are Avatar Agent and Design Agent. The UcVA agent in this paper is presented from various perspectives: structure, process, and use scenarios. A proposed application of these agent models and an analysis of User-centred Virtual Architecture designed by this agent illustrates and evaluates this approach to designing virtual architecture.

source	Gero JS and Brazier FMT (eds) (2002) Agents in Design 2002. Key Centre of Design Computing and Cognition, University of Sydney, pp. 181-200
summary	A simple learning mechanism was added to an agent-based computational design system to see if it could then transfer knowledge across problems. An existing system, A-Design, was enhanced by giving it the ability to store useful design knowledge in a memory store so that this knowledge could be used in new design problems. Three electromechanical design problems were used to evaluate this new learning mechanism, and results indicate that this simple learning mechanism is successful at transferring design knowledge to new problems with some limitations.

summary	We are now at a stage in which ICKT techniques allows us to develop knowledge intensive systems, such as intelligent decision support systems, to support collaboration and cooperation. This paper describes a theoretical approach, in which collaborative agents take on the role as a partner during the decision making process, in order to support various actors in the building process. The group-decision making set-up will be discussed and we will give an overview on the state of art of this subject. We will give some insights into their application in the building practice. In addition, we will provide some examples of use-case-scenarios as inception and early design support and evaluate it.
