title	A Situated Agent-Based Design Assistant
doi	https://doi.org/10.52842/conf.caadria.2004.145

summary	This paper introduces a situated agent-based design assistant. The agent is wrapped around an existing design tool in order to adapt that design tool to its use. Current design tools are unchanged by their use and as a consequence as the designer develops experience in using the tool, the tool remains the same. Such an agent is able to learn from its interactions with environments through its “experience”. This learning is based on situated representation mechanisms and a constructive memory system. The agent wrapper will be able to adapt the tool’s behaviours to its use and as a result improve the tool’s usability.

title	Crowd Modeling and Simulation

summary	The paper introduces a Multi Agent Systems (MAS) approach to crowd modelling and simulation, based on the Situated Cellular Agents (SCA) model. This is a special class of Multilayered Multi Agent Situated System (MMASS), exploiting basic elements of Cellular Automata. In particular SCA model provides an explicit spatial representation and the definition of adjacency geometries, but also a concept of autonomous agent, provided with an internal architecture, an individual state and behaviour. The latter provides different means of space-mediated interaction among agents: synchronous, between adjacent agents, and asynchronous among at-a-distance entities. Heterogeneous entities may be modelled through the specification of different agent types, defining different behaviours and perceptive capabilities. After a brief description of the model, its application to simple crowd behaviours will be given, and an application providing the integration of a bidimensional simulator based on this model and a 3D modelling application (3D Studio) will also be described. The adoption of this kind of system allows the specification and simulation of an architectural design with reference to the behaviour of entities that will act in it. The system is also able to easily produce a realistic visualization of the simulation, in order to facilitate the evaluation of the design and the communication with involved decision-makers. In fact, while experts often require only abstract and analytical results deriving from a quantitative analysis of simulation results, other people involved in the decision-making process related to the design may be helped by qualitative aspects better represented by other forms of graphical visualization.

title	A Critical Evaluation of Early Stages Software in its Capacity of Coping with Contextual Issues
source	LOCAL VALUES in a NETWORKED DESIGN WORLD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Stellingwerff, Martijn and Verbeke, Johan (Eds.), (2004) DUP Science - Delft University Press, ISBN 90-407-2507-1.
summary	In this paper we analyse critically early design stages software in its capacity of coping with contextual data at large (i.e. representing cultural, aesthetical context, etc.). We identified 5 categories of early stages software: geometry based graphic editors, evaluation architectural software, generative and shape-grammar based systems, evolutionary systems and other systems. Calling the object under creation during of the early stages a CAD conceptual model, we will investigate to what extend this software allows the architect to experience and represent the context in which a design is situated. Especially we will focus on its capacity to allow interaction, playful interaction on our way to the design. Designers, and particularly architects, interact with the local context similarly to interacting in a game: the context influences the users’ decisions, surprises them and causes permanent changes to their ways of thinking. On the other hand, architects permanently shape and reshape the context, and reduce the context to a protean point of reference. Such behaviour characterises creative thinking that is crucial for the early stage of design. The investigation led us to the conclusions that the effective interactivity with the context needs simple rules, a plain interface and data reduced as simple as possible, especially when interaction with the context is performed during the early stages of a design process. The findings can be used in organising computer environments for early-stage design.

title	Towards a Multi Agent System for the Support of Collaborative Design

summary	In this paper we are drafting the outline of a framework for a Multi Agent System (MAS) for the support of Collaborative Design in the architectural domain. The system we are proposing makes use of Machine Learning (ML) techniques to infer personalized knowledge from observing a users’ action in a generic working environment using standard tools such as CAD packages. We introduce and discuss possible strategies to combine Concept Modelling (CM)-based approaches using existing ontologies with statistical analysis of action sequences within a domain specific application. In a later step, Agent technologies will be used to gather additional related information from external resources such as examples of similar problems on the users hard disk, from corresponding work of team-members within an intranet or from advises of expert from different knowledge domains, themselves represented by agents. As users deny or reward resulting proposals offered by the agent(s) through an interface the system will be enhanced over time using methods like Reinforced Learning.

title	How to Construct an Audience in Collaborative Design - The Relationship Among which Actors in the Design Process
doi	https://doi.org/10.52842/conf.ecaade.2004.426
source	Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 426-434
summary	The features of complexity in architectural design have now been clarified. Complexity, intrinsic in architectural work, has increased in recent years as in all other fields of human endeavour – social, economic and cultural. In the specific case of architectural design, the most significant factors in this regard consist of the large number of actors, the numerous disciplines involved, technological innovation, regulations and rules governing the design process and the various different design aims. In order to address this complex of problems, long-term research based on the Collaborative Design paradigm, CD, is now being carried out. In it, thanks to the reciprocal exchange of information, the complementary nature of the knowledge possessed by the various actors, and the contemporary nature of the design action by the various actors on the same components, positive effects are exerted on the design as a whole. The latter thus gains in coherence and in improved integration among the design solutions proposed by the various actors. In CD all the actors are involved from the outset of the design work and are helped by distributed Knowledge Bases (KBs) and Intelligent Assistants (IAs). In this case it may happen that information and knowledge automatically exchanged among KBs (through the IAs) are excessive and/or not addressed to the right actors. How can information redundancy be avoided, and how can the flow of information sent over the network be controlled? The present paper introduces and defines the concept of „Audience“, that is, the group of actors to which it is permitted to send information concerning non respected requirements and the „reduced Audience“ to which to send the knowledge needed to overcome the difficulties encountered.

summary	The creation of virtual environments is becoming the alternative for spatial design, while what can be expanded from the real environment is often questioned. This paper proposes the agent interface based on curiosity to create human computer interaction in virtual exhibitive environments. From a social and behavioral point of view, this research explores the use of places as metaphors and simulative human-computer interactions in virtual environments by reactive agents and proactive curious agents based on situation detection. The process is demonstrated by a museum exhibition project. Both the physical and the virtual environment are built, and studied the human behaviors and experiences from their presence at both environments. Agent interfaces are adopted in the virtual environment to enhance people-to-people and people-to-place interactions. The development process, the observation, the interface agent, and discussion based on the findings are presented.

summary	Urban design involves coordination and communication for collecting consensus among citizens and developing the design strategy and spatial program. While these are web-based systems for representing the real world actions, there is lack of human interaction for receiving feedbacks during the process. Therefore, the purpose of this study is to introduce the agents into the participatory design process (PDP) based on scenarios. This paper has developed a webbased system prototype to demonstrate how the agent can interact with users and how the interface facilitates incremental design. We present a participatory design project in an old street to illustrate how the Scenario-Based Agent System (SBAS) model functions in a real application. Meanwhile, four issues will be discussed in regarding with building a learning interaction agent as an actor.

title	STUDY ON COMPUTER-AIDED DESIGN SUPPORT OF TRADITIONAL ARCHITECTURAL THEORIES
source	Technische Universität München
summary	The research presented in this thesis describes a computer-aided design support of traditional architectural theories. Traditional architectural theories in western architecture have been considered as a basis for answering the fundamental questions of architecture: proportion, symmetry, colour, harmony and so on. In particular, the aesthetic aspect of these theories has been one of many important architectural aspects, and which is concerned with the field of architecture in determining the beauty of architectural form. The most significant role of the traditional theories in architecture is to maintain unity, to avoid chaos and then to achieve harmony in a design, using some specific design principles. However, current technology-guided constructions tend to neglect often the importance of these theories due to the standardization of building elements, due to mechanically-prepared construction and the reducing completion costs, etc. Thus, this research proposes a design support system as a design assistant that gives an intelligent advice on architectural design, using analytical design- and ordering- principles of traditional theories for the optimization of the architectural design from the aesthetic perspective. To evaluate the aesthetic quality of an architectural design, this system is implemented in the AutoCAD environment, using the AutoLISP. It is applied so as to explain and develop aesthetic qualities of a design. Designs proposed by this system include optimum designs, which are based on the traditional architectural theories, and new ones which can be in future connected to information models. To do this, the definition of information about building elements is accomplished by using the neutral format EXPRESS and EXPRESS-G for such application systems. The results of the application system are presented, such as the easily generating and quickly conceptualising of an object model, the checking of the aesthetic value of the design during the various design phases, the helping to find direction during rational searching for a solution. The user can easily appreciate the usefulness of the proposed system as a set of tools for searching for rational architectural aesthetics and formal solutions at different design-stages. It is to be hoped that a new "traditional" fundamental of architecture, such as the proposed system, incorporating CAAD systems, will find its place among new technological methods in the AEC industry and so help to bridge the gap between the value of traditional architecture and CAAD systems.

summary	This paper presents an account of our research and development of processes providing seamless transition from design to fabrication. The narrative of our design, development, and prototyping experi¬ments spans seven years, including our current project, the Trusset software/structural system. Trusset is a combined building system and agent-based software design tool. The building system is based on a differential space-truss designed for fabrication entirely with computer numerically controlled (CNC) linear cutting devices, such as laser cut¬ters or three-axis mills. The software component is a set of agent-based design tools for developing surfaces and envelopes formally suitable to be built using the space-truss structure. Developed in parallel, the soft¬ware and building components combine within the Trusset system to provide a seamless pipeline from design to fabrication and assembly. The story of the development of software components and structural system, leading to the Trusset, act as a means of discussing the larger issues framing the research: the potential pitfalls and benefits of design and fabrication integration via the computer.

title	Improved Understanding of Urban Sprawl Using Neural Networks
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: 14020-2408-8, p. 33-49
summary	It is widely accepted that the spatial pattern of settlements is a crucial factor affecting quality of life and environmental sustainability, but few recent studies have attempted to examine the phenomenon of sprawl by modelling the process rather than adopting a descriptive approach. The issue was partly addressed by models of land use and transportation which were mainly developed in the UK and US in the 1970s and 1980s, but the major advances were made in the area of modelling transportation, while very little was achieved in the area of spatial and temporal land use. Models of land use and transportation are well-established tools, based on explicit, exogenouslyformulated rules within a theoretical framework. The new approaches of artificial intelligence, and in particular, systems involving parallel processing, (Neural Networks, Cellular Automata and Multi-Agent Systems) defined by the expression “Neurocomputing”, allow problems to be approached in the reverse, bottom-up, direction by discovering rules, relationships and scenarios from a database. In this article we examine the hypothesis that territorial micro-transformations occur according to a local logic, i.e. according to use, accessibility, the presence of services and conditions of centrality, periphericity or isolation of each territorial “cell” relative to its surroundings. The prediction capabilities of different architectures of supervised Neural networks are implemented to the south Metropolitan area of Milan at two different temporal thresholds and discussed. Starting from data on land use in 1980 and 1994 and by subdividing the area into square cells on an orthogonal grid, the model produces a spatial and functional map of urbanisation in 2008. An implementation of the SOM (Self Organizing Map) processing to the Data Base allows the typologies of transformation to be identified, i.e. the classes of area which are transformed in the same way and which give rise to territorial morphologies; this is an interesting by-product of the approach.

title	Artificial intelligence and emergence in architecture: A multi-agent based model for design processes
source	SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary	The purpose of this paper is to provide an alternative approach to traditional design process formulation and elaboration. In contrast to traditional models of design process fundamentally defined by the abstract manipulation of objects, this study recognizes that the resources available for rethinking architecture are to be found in a reformulation of its theory and practice. This reformulation should be based on non-linear design processes in which dynamic emergence and invention take the place of a linear design process fixed on a particular object evolution. Design is possible to be defined in two different and commonly confused ways; one as the process of designing or design activity and the second as the product of designing. In this study, we are concerned with design as a process to emphasize the misconceptions, derived from studying design products solely. Therefore, we propose a change from a design knowledge based on objects to a one focused on design as a network of processes.

summary	In this paper we report on recent developments in ARTHUR: an approach to support complex design and planning decisions for architects together with the simulation of pedestrian movement and the integration of existing CAD tools on the design table. Following a brief introduction, past and current work that has taken a similar approach will be reviewed. Next we describe a scenario that integrates agent-based simulations of pedestrian movement with space creation, and then give an overview of the system before finally discussing findings related to recent user evaluation studies of the system. This paper suggests that the integration of simulated pedestrian movement on the design table, while going through a cycle of reflection-in-action, plays a vital role in exploring possible design solutions and encourages new and different ways of thinking about design problems.

summary	Capturing and sharing design concepts is necessary if we want to support the design process by means of Information & Communication Technology (ICT). Standardized concepts are important for support at the end of the design process when designs need to conform to set standards and norms, and in order to enable communication, but are less useful in the early design stages. We propose an approach that takes into account a more developmental attitude that will be better suited for design support and the sharing of design concepts. In this approach, design concepts are formalised by means of a technology called concept modelling. Capturing and exchange of concepts are based on a multi-agent approach. The whole of concepts that are used in a domain or for a design task can be considered a design ontology. In this paper we outline the motivations for the research, outline the basic approach in the research work, and identify the major challenges and research problems that need to be tackled.

title	FROM REPOSITORY TO RESOURCE -- EXCHANGING STORIES OF AND FOR ARCHITECTURAL PRACTICE
source	Journal of Design Research, Volume 4, Issue 1, 2004 [ISSN 1569-1551]
summary	Central to Case-Based Reasoning (CBR) is the claim that knowledge in human memory takes the form of cases, i.e. interpreted representations of concrete experiences. The intimate relationship between knowledge and experience in design has inspired CBR researchers to develop various Case-Based Design tools, which try to support architects (and designers in general) in capitalizing on previous design experience. Typically, these tools is built around a case base, an indexed collection of concrete cases labeled by a set of characteristic features. In general, cases document buildings, i.e. design products. By contrast, Building Stories has chosen to complement product data by stories about the process that generated the product. Previous papers have documented and illustrated the ideas underlying Building Stories and situated the methodology with regard to other case study approaches. The present paper focuses on establishing the growing repository of building stories into a valuable resource of and for the profession.

summary	Cyberspace is more malleable than a physical environment, so it can afford much wider range of responsiveness. By applying the concept of place-making, we are experimenting virtual environments which are responsive to their users’ context-specific needs. Since objects are essential components that anchor the users’ various activities, having interactive objects in a 3D virtual environment is a major design concern for developing a dynamic and experience-rich virtual environment. We propose a layered agent model for intelligent behavior control of 3D objects, based on constraint solving process.

summary	This paper introduces a study of pedestrian behaviour modelling which incorporates ideas about agent-based systems and the traffic models based on the utility-maximization theory. The aim of this study is to examine the applicable scope of one of the basic assumptions in existing spatial behaviour models; the route with shortest distance maximizes the utility of each pedestrian’s travel. Although shortest-path models have been widely used in the field of Traffic management to predict routing behaviour, there can be seen a lot of erratic behaviour in urban areas, shopping migration behaviour for instance, which can not be explained by them. Thus, it is important to identify other possible influential factors on their utility maximization process in order to develop more explicable models of pedestrian movements. In this study, we implemented a simulation model using the shortest-path model as one of evaluation criteria of Genetic Algorithms (GA) to computationally emulate retail movements of shoppers in a big shopping centre and to test the accuracy of the model by comparison between the routes estimated by the model and actual trajectories of shoppers. This simulation system will be used as a platform for further modelling.

title	Space is the Machine, with a Ghost Inside
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Developments in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN 90-6814-155-4, p. 157-173
summary	The purpose of this paper is to report efforts towards the construction of a model for urban spatial dynamics simulation, based on multi-agents and space. The underlying idea is to have urban space producers and consumers operating in a two-layer, two-circuit model. The first layer holds urban space and its successive transformations; a second layer contains agents related to space; the first circuit simulates space production, and a second one simulates space consumption. Relationship between layers is represented as objective spatial features that agents are submitted to (the machine) and subjective meanings agents attach to each spatial feature (the ghost). While space works always in the same way, meanings vary according to each agent’s background and context. Relationships between circuits are represented by means of a market game in which producers try to maximize their profits by gambling with their risks, whereas consumers try to foresee the spatial distribution of local externalities that maximizes their utilities and investments. Urban Spatial Features are captured through centrality and land use patterns; every single agent’s action leads to changes in both patterns. Producers’ profit is a function of built form location. Consumers’ local externalities are concerned basically with present and future services. The model iteration is twofold: first it generates and allocates a number of built forms within a previously determined spatial system (a cellular matrix, for example), and second it allocates users to built forms. Population of users have its social profile and growth rate externally determined. Built form allocation is decided on the basis of a combination of profitXrisk perspectives. Users’ locational choice is supported by accessibility to services and present/future neighbourhood profile. Built form allocation works as parameter for users’ locational assessment, whereas users’ choices are used as parameters for developers. The model tends to adjust itself, in terms of quantities and types of built forms to be erected, although through a market lag of some iterations. Allocations are always made through weighted draws, so that mutations (non deterministic allocations) do occur.
