summary	There is an essential contradiction between the making of buildings or built environments in a threedimensional modeler and the graphic control of this process. Three-dimensional modeling is a constructive activity, in which solids are assembled as they would be in an actual structure; it benefits the designer. Presentation and documentation, on the other hand, are prescriptive activities that direct some of the construction and all the visualization and criticism of the proposal; they benefit the user and builder. A building while being designed can be visualized and criticized from its solid model, and the model can take a variety of forms depending on its part): computer-based, drawn in orthographic or perspective projection, constructed of cardboard or wood, or described narratively by means of text, programmatic data, performance model or animation. However, practicing architecture is the process of recording and communicating the decision making process and the contractual obligations that result. In actual practice, in contrast to the designer directed ideal, more participants are brought in sooner at the beginning of a project and with more publicity, which in turn means keeping more, not fewer, records. As the profession evolves, records of the string of design decisions will become more automated, more carefully structured and more retrievable. More buildings will be "tracked" and exposed to review in this way because public environmental sensitivity will improve. The communication between a single designer and his own thoughts will become less and less important.

title	A model appraising the performance of structural systems used in sports hall and swimming pool buildings in greece

summary	The selection of the best performing structural system (among steel, timber laminated, concrete, fabric tents) for medium span (30-50m) sports halls and swimming pools in Greece formed the impetus for this research. Decision-making concerning selection of the structural system is difficult in this sector of construction, as was explained in the "Long Span Structures" conference (November 1990, Athens. Greece). From the literature it has been found that most building appraisals end up at the level of data analysis and draw conclusions on the individual aspects they investigate. These approaches usually focus on a fraction of the problem, examining it very deeply and theoretically. Their drawback is loss of comprehensiveness and ability to draw conclusions on an overall level and consequently being applicable to the existing conditions. Research on an inclusive level is sparse. In this particular research project, an inclusive appraisal approach was adopted, leading to the identification of three main variables: resources, human-user-satisfaction, and technical. Consequently, this led to a combination of purely quantitative and qualitative data. Case studies were conducted on existing buildings in order to assess the actual performance of the various alternative structural systems. This paper presents the procedure followed for the identification of the research variables and the focus on the development of the model of quantification. The latter is of vital importance if the problem of incompatibility of data is to be solved, overall relation of findings is to be achieved and holistic conclusions are to be drawn.

title	Working with prototypes: from cad to flexible tools for integrated building design
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	The formulation of design knowledge as concepts, goals and rules cannot be captured in fixed and valid statements. The dynamic modelling of concepts and goals is, on the contrary, part of the design process itself. Tools that effectively support architects in their design should therefore never use predefined mechanisms, but must be definable interactively according to design specifications. We propose the concept of prototypes as a cognitive model to represent and structure design knowledge. Prototypes incorporate an individual view of design in a synthetic and organizational model for a defined area of interest. They actively control and guide design processes in supporting the organizational concepts for solutions. The a+Tool implements these concepts on the basis of a modelling language. It provides a dynamic toolkit and user interface to support design as well as knowledge modelling.

title	Environmental Compatibility and Computer Aided Decision MakingRelated to the Third University in Rome: An Integrated Application of Several Methods
doi	https://doi.org/10.52842/conf.ecaade.1993.x.j1x
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
summary	The EC Human Capital and Mobility Project, has allowed collaboration between Universita' di Roma .'La Sapienza", and University of Strathclyde (Glasgow), on a research programme developed by the author. The research consists on an integrated application of assessment methods that will allow designers, planners, and public administrators to operate on defined rules, to evaluate "a priori" the designing and planning parameters. The new integrated operating method, could be used for the elaboration of developing urban plans, or even for public design competition assessment.

title	A decision-making process for choice of a flexible internal partition option in multi-unit housing using decision theory techniques
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	Recent demographic changes have increased the heterogeneity of user groups in the North American housing market. Smaller households (e.g. elderly, single parent) have non-traditional spatial requirements that cannot be accommodated within the conventional house layout. This has created renewed interest in Demountable/Flexible internal partition systems. However, the process by which designers decide which project or user groups are most suited for the use of these systems is quite often complex, non-linear, uncertain and dynamic, since the decisions involve natural processes and human values that are apparently random. The anonymity of users when mass housing projects are conceptualized, and the uncertainty as to the alternative to be selected by the user, given his/her constantly changing needs, are some contributing factors to this effect. Decision Theory techniques, not commonly used by architects, can facilitate the decision-making process through a systematic evaluation of alternatives by means of quantitative methods in order to reduce uncertainty in probabilistic events or in cases when data is insufficient. The author used Decision Theory in the selection of flexible partition systems. The study involved a multi-unit, privately initiated housing project in Montreal, Canada, where real site conditions and costs were used. In this paper, the author outlines the fundamentals of Decision Theory and demonstrates the use of Expected Monetary Value and Weighted Objective Analysis methods and their outcomes in the design of a Montreal housing project. The study showed that Decision Theory can be used as an effective tool in housing design once the designer knows how to collect basic data.

title	Graphical interfacing to a conceptual model for estimating the cost of residential construction
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	This paper presents a method for determining elemental square foot costs and cost significance for residential construction. Using AutoCAD's icon menu and dialogue box' facilities, a non-expert may graphically select (i) residential configuration; (ii) construction quality level; (iii) geographical location; (iv) square foot area; and finally, (v) add-ons, e.g. porches and decks, basement, heating and cooling equipment, garages and carports etc. in order to determine on-site builder's costs. Subsequent AutoLisp routines facilitate data transfer to a Lotus 1-2-3 spreadsheet where an elemental cost breakdown for the project may be determined. Finally, using Lotus 1-2-3 macros, computed data is transferred back to AutoCAD, where all cost significant items are graphically highlighted.

title	The use of computer visualisation in planning control: An investigation of its utility in selected examples
source	Town Planning Review, 64(2), pp. 193-212
summary	A study was undertaken of the application of computer visualisation to the control of design by local planning authorities in England. Several examples of major urban development and routine development control work were visualised for local councils, the images fed back into the decision-making process, and the results monitored. While the investigation of the decision-making process is still continuing, the results obtained to date demonstrate an important role for visualisation. The work undertaken is described and comment is made on both the pattern of possible use by a planning authority and the general issue of the objectivity of the images.

title	Design support via simulation of building and plant thermal interaction
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	Design decision support related to building energy consumption and/or indoor climate should be based on an integral approach to the environment, the building, heating, ventilating and air-conditioning (HVAC) system, and the occupants. The tools to achieve this are now available in the form of computer simulation systems which treat the building and plant as an integrated dynamic system. Although its potentials reach beyond the area of Computer Aided Building Design, the paper describes building and plant energy simulation within the context of CABD, design decision support and design evaluation. Currently, computer simulation is only used indirectly as a design decision support mechanism; that is, its power is not delivered very efficiently to the design profession. This paper suggests some future research directions. These are aimed at providing a mechanism to overcome this problem by developing an intelligent front end' which bridges the gap between sophisticated computer simulation tools and the design profession.

source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary	Presently, only a small percentage of people in the world typically hire an architect to design and build a home which is tailored to their preference. Besides the architect’s fee, clients also need to wait an interminable time for design and construction. Factory-made prefabricated housing systems tried to solve this problem previously. However, most pioneers failed to address the issues of variability and individual needs (Kieran & Timberlake, 2004). Plants closed because they produced more than the market demand, and prefabricated housing provided less flexibility than the traditional stick-built housing. The advanced digital technology makes it possible to communicate design ideas and concepts to others more effectively. The project delivery process leads itself to customization, embodying principles of lean production (Pine, 1993), flexible computer-integrated design interaction with clients, and reduced cycle times; all effecting rapid response between consumers and producers.

title	An approach to evaluating exhibition spaces in art galleries
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	There are certain building types in which movement of people is the most significant evaluation factor. Among these are art galleries and museums. Unlike other building types, which are often explicated by investigating the relationship between people and people, and between people and the built environment, art galleries and museums are a building type in which the social relationship between people hardly exists and peoples movement through space, that is, the functional relationship between people and space, is one of the most significant factors for their description. The typical museum experience is through direct, sequential, and visual contact with static objects on display as the visitor moves. Therefore, the movement pattern of the visitors must exert a significant influence on achieving the specific goal of a museum. There is a critical need for predicting the consequences of particular spatial configurations with respect to visitors movement. In this sense, it is the intention of this paper to find out the relationship between the spatial configuration of exhibition space and the visitors' movement pattern.

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	A functional approach to realizing decision support systems in technical regulation management for design and construction
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	Technical building standards defining the quality of buildings, building products, building materials and building processes aim to provide acceptable levels of safety, health, usefulness and energy consumption. However, the logical consistency between these goals and the set of regulations produced to achieve them is often hard to identify. Not only the large quantities of highly complex and frequently changing building regulations to be met, but also the variety of user demands and the steadily increasing technical information on (new) materials, products and buildings have produced a very complex set of knowledge and data that should be taken into account when handling technical building regulations. Integrating knowledge technology and database technology is an important step towards managing the complexity of technical regulations. Generally, two strategies can be followed to integrate knowledge and database technology. The main emphasis of the first strategy is on transferring data structures and processing techniques from one field of research to another. The second approach is concerned exclusively with the semantic structure of what is contained in the data-based or knowledge-based system. The aim of this paper is to show that the second or knowledge-level approach, in particular the theory of functional classifications, is more fundamental and more fruitful. It permits a goal-directed rationalized strategy towards analysis, use and application of regulations. Therefore, it enables the reconstruction of (deep) models of regulations, objects and of users accounting for the flexibility and dynamics that are responsible for the complexity of technical regulations. Finally, at the systems level, the theory supports an effective development of a new class of rational Decision Support Systems (DSS), which should reduce the complexity of technical regulations and restore the logical consistency between the goals of technical regulations and the technical regulations themselves.

title	Efficiency of Model Endoscopic Simulation - An Experimental Research at the University of Stuttgart
source	Endoscopy as a Tool in Architecture [Proceedings of the 1st European Architectural Endoscopy Association Conference / ISBN 951-722-069-3] Tampere (Finland), 25-28 August 1993, pp. 31-34
summary	At the Institute of Urban Planning at the University of Stuttgart early experiments were made with the help of endoscopes in the late 1970’s. The intention was to find new instruments to visualize urban design projects. The first experiment included the use of a 16 mm film of a 1:170 scale model of the market place at Karlsruhe, including design alternatives (with trees, without trees etc). The film was shown to the Karlsruhe authorities, who had to make the decision about the alternatives. It was said, that the film gave a great help for the decision-making and a design proposition had never before been presented in such understandable way. In 1975-77, with the support of the Deutsche Forschungsgemeinschaft (German Research Foundation) an investigation was carried out into existing endoscopic simulation facilities, such as those in Wageningen, Lund and Berkeley. The resulting publication was mainly concerned with technical installations and their applications. However a key question remained: ”Can reality be simulated with endoscopy?” In 1979-82, in order to answer that question, at the Institute was carried out the most extensive research of the time, into the validity of endoscopic simulation. Of special importance was the inclusion of social scientists and psychologists from the University of Heidelberg and Mannheim. A report was produced in 1983. The research was concerned with the theory of model simulation, its ways of use and its users, and then the establishment of requirements for effective model simulation. For the main research work with models or simulation films, psychological tests were developed which enabled a tested person to give accurate responses or evidence without getting involved in alien technical terminology. It was also thought that the use of semantic differentials would make the work imprecise or arbitrary.

source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	This paper illustrates a model used to construct the evaluation module for An Interface for Designing (AID), a system to aid architectural design. The model can be used at the end of every cycle of analysis-synthesis-evaluation in the intermediate phases of design development. With the aid of the model it is possible to evaluate the quality of a project in overall terms to establish whether the project is acceptable, whether it should be elaborated ex-novo, or whether it is necessary to begin a new cycle to improve it. In this last case, it is also possible to evaluate the effectiveness of the possible actions and strategies for improvement. The model is based on a procedure of trichotomic segmentation, developed with MCDA (Multi-Criteria Decision Aid), which uses the outranking relation to compare the project with some evaluation profiles taken as projects of reference. An application of the model in the teaching field will also be described.

title	Measuring the effect of attention on simple visual search
source	Journal of Experimental Psychology: Human Perception and Performance 19(1) 108-130.
summary	It is unclear to what extent attention affects perception rather than memory and decision. Is all of perception limited by attention, or is perception completely preattentive, and attention only affects memory and decision, or some compromise? The answer is in your definitions of these phenomena. Visual search task: display set size The display set size increases response time and/or response accuracy. This is a putative example of divided attention in the literature. The goal of this paper is to be more rigorous in studying this setsize phenomena, and try and decouple attention on perception Display set size: The total number of stimuli in an experiment. Relevant set size: Total number of 'cued' stimuli in an experiment.

title	Ratios for cost control
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	The design of buildings takes place in phases representing a development from rough to precision planning. Estimates are made in order to test whether the result is still within the budget set by the client or developer. In this way, the decisions taken during the design phase can be quantified and expressed in monetary terms. To prevent blaming the wrong person when an overrun is discovered, the cost control process has to be improved. For that purpose, two new procedures have been developed: (i) a new translation activity; and (ii) ratios by which quantities can be characterized. 'Translation is the opposite of estimation. A monetary budget is converted -'translated' - into quantities, reflecting the desired quality of the building materials. The financial constraints of the client are thus converted into quantities - the building components used by the designers. Characteristic quantity figures play an important role in this activity. In working out an estimate, the form factor (i.e., the ratio between two characteristic values of a building component) has to be determined. The unit cost is then tested against that ratio. The introduction of the 'translation' activity and the use of characteristic quantity figures and form factors enhance existing estimation methods. By implementing these procedures, cost control becomes considerably more reliable.

source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	In this paper we present a hierarchical decision support system for the allocation of organisations to available buildings, and for the allocation of employees of an organisation to the work units of a building. For both allocation problems a mathematical model and optimisation algorithm is developed, taking into account the relevant criteria, such as the extent to which the allocated floorspace is in accordance with the standards, and the extent to which departments are housed in connecting zones of a building. The decision support system is illustrated by two practical applications.

title	Decision support system for air base construction operations
source	The Int. Journal of Construction IT 1(2), pp. 69-82
summary	The United States Air Force has recently introduced a CAD software performing air base planning and operability functions. This paper presents a prototype system developed to support that software in enhancing decision-making processes for construction operations, by integrating its CAD/graphics capabilities with a database management system (DBMS). The system addresses the complexity and unique nature of the air base environment and takes due account of the importance of the efficient utilization of resources. It assists in the generation of alternative solutions and furnishes comparative and indicative evaluations of these, thus providing the decision maker with proper guidance towards the expeditious selection of good solution. System fundamentals and the rationale behind them are described. A typical scenario is presented, illustrating the concepts developed and demonstrating the potential benefits of the system as a practical decision-support tool. Although originally aimed for an air base environment, the proposed solution could also readily apply to civilian systems of similar characteristics.

summary	Architects and urban designers are increasingly using computers in their attempt to improve decision making in urban design. Most existing systems emphasize hard data such as statistics, land use data, etc. In recent years with the use of more powerful computers we have seen a greater emphasis on managing visual data. Computer systems are being used to generate urban models and simulations of the various kinds of impact new developments have on the existing cityscape. This project emphasizes the use of visual data. The purpose of the research has been to develop a computer system for urban designers to use in analyzing urban architectural qualities. Therefore this project focuses on applying traditional methods and theories of urban designers rather than developing new computer techniques. The traditional methods and theories of urban designers fall within the category which the French theorist Francoise Choay calls Pre-urbanism and Urbanism - the Cultural Model. Theorists within this category include Camillo Sitte, Gordon Cullen, Kevin Lynch, Leon Krier, Aldo Rossi, Michael Trieb, Roger Tranzick and Thiis-Evensen. This computer system has been developed as a prototype in order to gain experience and knowledge for future development of a large system. Later development will be based upon a vectorized threedimensional model of a whole city using texture mapping and tracing techniques to annotate important architectural features. The computer system consists of the basic analysis module supplied with a simulation unit and a theory unit. With this analytical tool, analysis is conducted on three different urban scales. The prototype has been developed on the Macintosh computer with SuperCard as the authoring tool. The computer system was developed as a prototype for Danish Urban Designers and is currently being tested in conjunction with the city of Viborg, Denmark. ( population 55,000). Located in Jutland, Viborg was the capital of Denmark around the year 1000. It now functions as a center for regional government. Viborg was selected as the test site because of its historical core.
