title	Customer Configuration Systems as a Design Task: Architectural education and context-driven product configurator design
source	De Luca, F, Lykouras, I and Wurzer, G (eds.), Proceedings of the 9th eCAADe Regional International Symposium, TalTech, 15 - 16 June 2023, pp. 99–104
summary	This research deals with customer configuration systems for architecture and design products as a design task for students. The design of a product configurator accompanying the parametric design of a piece of furniture or an architectural element has been introduced in several courses over the last ten years at the HafenCity University Hamburg and at Hamburg University of Technology by the author. These studios are presented as case studies to discuss the didactic potential that lies in designing customer oriented product configuration systems with students of design and architecture.

title	Urban Street Space Analysis with Spherical Box-Counting: Holistic digital Gestalt analysis of architecture in urban space
doi	https://doi.org/10.52842/conf.ecaade.2024.2.567
source	Kontovourkis, O, Phocas, MC and Wurzer, G (eds.), Data-Driven Intelligence - Proceedings of the 42nd Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2024), Nicosia, 11-13 September 2024, Volume 2, pp. 567–576
summary	Spherical box-counting of urban street spaces is a novel method developed and refined by the authors to produce highly specific topological fractal fingerprinting of architecture in relation to observer position and in the context of the accompanying surroundings. The use of 360-degree spherical panoramas as input data and basis for fractal measurement lies at the center of this method. A holistic approach toward architectural and urban design, balancing between simplicity and complexity of all Gestalt qualities, needs to take the influence of every (especially man-made) object in view into consideration. This research shows that Gestalt complexity is linked to the observer’s viewpoint as well as the Gestalt complexity of all objects visible from the viewer’s position. This is another decisive step toward holistic fractal and overall digital Gestalt analysis of urban spaces.

summary	For over 10 years the author has been a teacher in the field of "computer application in architecture" at the Fachhochschule. Since 1985 he regularly has been taking part in the conferences of A.I.I.D.A. (Arbeitskreis INFORMATIK IN DER ARCHlTEKTENAUSBILDUNG). All the faculties of architecture at the Fachhochschulen (about 10) can send their representatives of CAAD to the conferences. A.I.I.D.A. has been having 2 conferences a year since 1985. At the last conference in Wiesbaden a paper with statements of A.I.I.D.A. for the further education in CAAD was finished. The author presents and explains this paper. On the other hand he shows the actual education program of CAAD of his faculty. The education in CAAD started in 1972 with basic information without practical elements. Now the practical work with the workstation is talking most of the time . The computer application is available for subjects like Building Economics, Building and Structure Design and others. With his assistant the author developed programs of the field of Building Economics. In 1986 he started introduce CAD with AutoCAD in the education program. Now also other colleagues start to integrate CAAD into their subjects.

title	Constructive Representation in Situated Analogy in Design. An essay on a bottle of Eau d'Issey pour Homme
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 507-520
summary	A model of situated analogy considered within the context of design is presented. It shows the impact of constructive knowledge representation on analogy making. The importance of a non-fixed but constructive representation is highlighted. It is suggested that a situated model of analogy fits the observed characteristics of design better than a non-situated one.

title	Traffic Flow Landscapes
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary	Major metropolitan areas and constituent independent jurisdictions face the problem of providing efficient transportation for their residents and in-and out commuters. A typical trip taker spends considerable time on the road to reach the workplace and other destinations. Though it may seem counter-intuitive, adding more links to existing road networks and/or increasing traffic capacity by adding lanes does not necessarily decrease travel times (eg. Braess' paradox). But it is certain that a dense redundant network of roads would provide a trip taker with alternate routes when traffic incidents occur. These types of questions raise the question of, how to evaluate the flow characteristics of the entire road network of a jurisdiction and its larger region in keeping the traffic moving? Further, how may the impact of adding more links/ lanes or the blocking of existing links! lanes be best measured? To answer these and related questions, we propose a methodology to evaluate a fitness criteria for road networks based on Kauffman's biological NK model (1993). We specify a transportation road traffic flow landscape analogous to the fitness landscape of the NK model. Using the transportation road traffic flow landscape we derive a road fitness index that can be used to evaluate either the entire road network's traffic flows or subparts of such network's traffic flows. We explore the possibility of investigating traffic flow landscapes to search for optimal routes to clear traffic. Finally we describe an approach for applying the theoretical framework developed in the paper to the traffic conditions on the road network of the city of Fairfax, Virginia.

title	Architecture and Industrial Design A Convergent Process for Design
doi	https://doi.org/10.52842/conf.acadia.2006.079
source	Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 79-94
summary	The use of technology has grown with the way design professions have evolved over time. Changing needs, desires of comfort, and perceptions of the consumers have led to a distinct improvement in the design of both product and architecture. The use of the digital media and emerging technologies has brought a dramatic change to the design process allowing us to view, feel, and mould a virtual object at every stage of design, development, and engineering. Change is often quick and easy since a virtual product does not inherently carry the biases of its physical counterpart. In order to communicate ideas across the team, digital processes are also used to bring together opinions, experiences, and perspectives. These methods encourage decision making based on information rather than prejudice or instinct. Thus, digital exchanges (technology) impact firm strategies at three levels: product, process, and administrative or support activities (Adler 1989).Digital tools for design exchange in Industrial Design (ID) began much earlier than many other professions. The profession of Architecture is also slowly moving to a similar model with digital exchange finding increasing prevalence in drawing, modeling, performance simulation, design collaboration, construction management, and building fabrication. The biggest problem is the disintegrated use of technology in the architectural profession without a strategy toward streamlining the design process from conception to fabrication. In this paper we investigate how the use of technology has evolved in the professions of Industrial Design and Architecture comparatively in their product, process, and support activities. Further, we will present a set of guidelines that will help architects in the convergence of design process, helping in a more efficient work flow with a strategic use of digital technology.

title	Efficient rendering of trimmed NURBS surfaces
source	Computer-Aided Design, Vol. 27 (7) (1995) pp. 509-521
summary	An algorithm for the interactive display of trimmed nurbs surfaces is presented. The algorithm converts the nurbs surfaces to Bézier surfaces, and nurbs trimming curves toBézier curves. It tessellates each trimmed Bézier surface into triangles, and renders them using the triangle rendering capabilities common in current graphics systems. Itmakes use of tight bounds for the uniform tessellation of Bézier surfaces into cells and it traces the trimming curves to compute the trimmed regions of each cell. Thisoperation is based on the tracing of trimming curves, intersection computation with the cells, and triangulation of the cells. The resulting technique also makes use of spatialand temporal coherence between successive frames for cell computation and triangulation. Polygonization anomalies such as cracks and angularities are avoided as well. Thealgorithm can display trimmed models described using thousands of Bézier surfaces at interactive frame rates on high end graphics systems.

title	Cyber-Physical Robotic Process for Re-Configurable Wood Architecture - Closing the circular loop in wood architecture
doi	https://doi.org/10.52842/conf.ecaade.2021.2.181
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 2, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 181-188
summary	The concept of circularity implies that materials, components, systems can be re-utilized to reduce their environmental impact by extending their life-cycle. This paper discusses an approach to circular construction that revolves around transformable wood architecture. What if we can make buildings that can be assembled, disassembled, and re-assembled by robots in infinite circular loops of reconfigurations? To explore this concept, a robotic process is developed to automate the reconfiguration of timber structures, considering the material, geometric and processual challenges involved in the operations. This method entangles establishing a cyber-physical process based on visual and force feedback, the development of wood construction elements suitable for the process, the deployment of design algorithms for semi-autonomous online construction. The paper describes this setup and demonstrates its functionality through a set of experimental prototypes conceived and evaluated in a three-phase collaborative process of assembly-disassembly-reassembly.

title	Collaborative design and construction of reconfigurable wood structures in a Mixed Reality environment

summary	Mixed Reality tools offer new possibilities for cyber-physical design and construction and promote novel collaboration protocols. This work tackles a multi-user open-end design and construction of reconfigurable timber structures in Mixed Reality by introducing a computational workflow, physical setup and custom-designed interface. The developed procedures are demonstrated in the design and making of a real-scale architectural mock-up based on a discrete construction kit that allows for numerous assembly combinations. The results show that such a construction system that is characterized by rich design and assembly data is processed faster and with fewer mistakes by the builders using Mixed Reality. This opens the possibility to execute, change and update the construction directly in the physical environment in real-time. Moreover, the projected holographic analytics and construction data allowed for more structured decision-making and understanding of the impacts that each building action had.

title	The Virtual Design Team
source	Communications of The ACM, Vol. 41, No. 11, November, 1998
summary	The long range goal of the Virtual Design Team" (VDT) research program is to develop computational tools to analyze decision making and communication behavior and thereby to support true organizational (re)engineering. This article introduces the underlying theory, the implementation of the theory as a computational model, and results from industrial test cases. Organization theory traditionally describes organizations only at an aggregate-level, describing and predicting the behavior of entire organizations in terms of general qualitative predictions. We define and implement a "micro" theory of the structure and behavior of components of organizations, explicitly representing activities, groups of people called "actors," and organizational structure and policies for project teams. A VDT model can be "run" by a discrete event simulation. Emergent aggregate model output behaviors include the predicted time to complete a project, the total effort to do the project, and a measure of process quality. More detailed model behaviors include the time-varying backlog of individual actors and the "exceptions" associated with activities. The results are detailed and specific, so they can guide specific managerial interventions in a project team and can support sensitivity studies of the relative impact of different organizational changes. We conclude that such a theory is tractable and predictive for complex but relatively routine, project-oriented design tasks. The application for which VDT offers unique new kinds of insights is where an organization is striving to shrink time to market dramatically for a product that is similar to ones it has previously developed. Reducing time to market dramatically almost always requires that previously sequential activities are executed more concurrently. In this situation, experienced managers can still correctly identify the required activities and estimate their durations and skill requirements; but they almost always underestimate the increased workload arising from exponentially higher coordination needs and the propagation of rework between the now highly concurrent activities. The VDT framework, which explicitly models information dependency and failure propagation between concurrent activities, has proven to be far more accurate, and to incorporate a wider range of parameters, than CPM/PERT process models for these fast-paced development projects."

summary	This research paper concentrates on a conceptual framework for the creation of high-level procedural city models. A workflow is presented, which enables users to create city models in an intuitive way by using design-code-driven building typologies. This drastically advances traditional procedural city modelling where usually low-level implementations of city model components take place. New planning methods and instruments have to be developed for the growing demand of the rapid environmental, social and economic changes in cities and agglomerations. The presented method allows for quick visualization and iteration by using urban planning typologies.

summary	This paper focuses on the definition of a conceptual participatory design framework for urban planning. Traditional planning methods can no longer satisfy the growing demands on sustainable urban planning in regard to factors such as complexity, problem size, and level of detail and these limitations make the development of new approaches necessary. Expert knowledge as well as insights from stakeholders and community members needs to take part equally in the decision-making process since they are responsible for a broad understanding and acceptance of final planning decisions. Therefore, a participatory framework is presented in the following, which integrates needs and requirements of stakeholders. In order to enable diverse groups of stakeholders to act conjointly, we propose the application of interactive decision support tools, which will leverage general conclusions especially to solve crucial zplanning decisions.

title	Unsupervised Dynamic Concurrent Computer-Aided Design Assistant
source	Los Angeles: UCLA
summary	The increasing capability of computer-aided architectural design systems has strengthened the role that the computer plays in the workplace. Due to the complexity of developing new techniques and research, these systems are undertaken mostly by scientists and engineers without significant architectural input (Willey, 1991). The design concept of these systems may be based on a well-defined and well-understood process, which is not yet realized in architectural design (Galle, 1994). The output of such research may not be easily adapted into the design process. Most of the techniques assume a complete understanding of the design space (Gero and Maher, 1987) (Willey, 1991). The description or construction of the design space is always time and space consuming, and the result can never be complete due to the ever-changing nature of architectural design. This research intends to initiate a solution for the above problems. The proposed system is an unsupervised-dynamic-concurrent-computer-aided-design assistant. The “unsupervised” means the learning process is not supervised by the user because it is against the designer's nature to “think-aloud” in the design studio and it also increases the work load. It is dynamic because the size of the knowledge base is constantly changing. Concurrent means that there are multiple procedures active simultaneously. This research focuses on learning the operational knowledge from an individual designer and reapplying it in future designs. A computer system for this experiment is constructed. It is capable of The preliminary result shows a positive feedback from test subjects. The purpose of this research is to suggest a potent computational frame within which future developments may flourish.
