title	SOME EPISTEMOLOGICAL CONCERNS REGARDING ARTIFICIAL INTELLIGENCE AND KNOWLEDGE-BASED APPROACHES TO ARCHITECTURAL DESIGN - A RENEWED AGENDA
source	Education and Practice: The Critical Interface [ACADIA Conference Proceedings / ISBN 1-880250-02-0] Texas (Texas / USA) 1993, pp. 155-162
doi	https://doi.org/10.52842/conf.acadia.1993.155
summary	It has been noted that designers - when confronted with computers - have, by and large, refused to accept the introduction of apparently new design methodologies, and it has been speculated that this is the result of a failure of those methodologies to address the cognitive processes which take place in the course of designing. This position is somewhat suspect in that such innovations as computer-aided drafting -which also fail to recognize these processes have been widely accepted. It is perhaps more likely that the lack of acceptance results from a perception on the part of designers that the new methodologies either do not reflect some or all of those concerns that designers consider fundamental to design, or that they actively interfere with the designer's ability to accomplish what he/she sees as the goals of design. Given that the application of artificial intelligence and related work to architecture is still in its infancy, all of this suggests the need for a reassessment of the role of computing in design in order to clarify and strengthen those roles deemed appropriate. Two approaches to the integration of artificial intelligence and knowledge-based systems into architectural design practice are currently dominant. One attempts to create systems which can on their own produce designs, the other provides intelligent support for those doing design. It was, in part, the recognition of limitations in the ability of traditional CAD systems and building modelers to reflect what designers actually do that led to explorations into the idea of intelligent assistants. Development of such assistants was aided by research into the act and process of design through protocol and other studies. Although some work is currently being done in the development of artificial intelligence and knowledge based applications in architecture, and work continues to be done on the study of design methodologies, the bulk of available information in each of these areas remains in the realm of design disciplines related to but outside of architecture and do not reflect the explicit role of architectural design in the embodiment and expression of culture. The relationship of intelligence to culture has resulted in some skepticism regarding the ultimate capacity of neural nets and symbolically programmed computers in general. Significant work has been done questioning the rational tradition in computer development for its failure to address phenomena which are not easily subject to scientific analysis. Further skepticism regarding the role of artificial intelligence and knowledge-based or expert systems in architectural design has been emerging recently. Such criticism tends to focus on two issues: the nature of drawing as an activity which involves both the generation and interpretation of graphic artifacts, and the nature of the human designer as an active agent in the design process.

title	Personality assessment in regard to design strategies
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 discusses some preliminary results of several knowledge-acquisition and documentation-structuring techniques that were used to assess the working styles of architects. The focus of this assessment was on their strategic design behaviour. Hettema's Interactive Personality Model (Hettema 1979, 1989) was used to explain and interpret these results. The methods used to acquire the necessary data are protocol analysis, card sorting and interviews. The results suggest that at least three parameters can be used to explain and differentiate the strategic design behaviour of architects. These parameters are S (site-oriented), B (brief-oriented) and C (concept-oriented). A priority hierarchy of these parameters reveals six major distinguishable working styles. These results are captured in a new design model that can be used in data bank implementations.

summary	IPER (hypertext for the knowledge of building patrimony) is the result of a research developed with C.N.R. (National Research Institute). The aim of IPER is to provide the knowledge, the description and the management of one or more historical buildings for public or private institutions. IPER allowed us to improve our methodology of building analysis, covering various disciplinary fields, in two different systems. (1.) the first one, synthetic and suitable for a group of historical buildings, (2.) the second one, complex and particularly made for monumental buildings. // This experience is related to the new regulation of teaching architecture in Italy made in 1993. The main novelty is the introduction of the laboratories with the contemporary presence of two or three teachers of different disciplines, working together with the students on the same project with different approaches. This opportunity allowed us to introduce the "knowledge engineer" as a teacher in the laboratory of building technology. IPER is given to the students with the aim of experimenting and solving the theoretical and practical difficulties that students of different years may encounter in the knowledge and representation of buildings and in the organisation of all the data from the case study.

title	Design Tool Integration: Model Flexibility for the Building Profession
source	Proceedings of Building Systems Automation - Integration, University of Wisconsin-Madison
summary	The development of ICAtect, as discussed in the Building Systems Automation and Integration Symposium of 1991, provides a way of integrating simulation tools through a common building model. However, ICAtect is only a small step towards the ultimate goal of total integration and automation of the building design process. In this paper we investigate the next steps on the path toward integration. We examine how models structured to capture the physical attributes of the building, as required by simulation tools, can be used to converse with knowledge-based systems. We consider the types of mappings that occur in the often different views of a building held by these two classes of design tools. This leads us to examine the need for multiple views of a common building model. We then extend our analysis from the views required by simulation and knowledge-based systems, to those required by different segments of the building profession (e.g. architects, engineers, developers, etc.) to converse with such an integrated system. This indicates a need to provide a flexible method of accessing data in the common building model to facilitate use by different building professionals with varying specialities and levels of expertise.

title	A Hierarchical Model for Building Applications
source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 423-435
summary	Advanced computer-aided architectural applications must model buildings as multi-level compositions supporting distinct points of view. Hierarchies of encapsulated, autonomous elements can be derived from ISO-STEP's General AEC Reference Model and configured for various applications. For analysis of life-cycle costs, we define a Pyramid of evaluable production steps leading to the final building; for optimization of renovation task schedules, a topological model of access paths and traffic flow. These separate viewpoints can be embedded in a single unifying structure permitting the communication and propagation of changes among its specialized aspects.

title	A model appraising the performance of structural systems used in sports hall and swimming pool buildings in greece
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 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	Knowledge and data modelling in cad/cam applications
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	Modelling knowledge and data in CAD/CAM applications is complex because different goals and contexts have to be taken into account. This complexity makes particular demands upon representation formalisms. Today many modelling tools are based on record structures. By analyzing the requirements for a product model of a portal structure in steel, this paper shows that in many situations record structures are not well suited as a representation formalism for storing knowledge and data in CAD/CAM applications. This is illustrated by performing a knowledge-level analysis of the knowledge and data generated in the design and manufacturing process of a portal structure in steel.

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.

doi	https://doi.org/10.52842/conf.ecaade.1993.x.w2h
summary	The interdisciplinary research project aims at the development of a hard- and software environment to support the representation, analysis, manipulation and design of urban development areas for architects and city planners. It was started in 1990 and involves three groups at the ETH Zurich: Architecture/Urban design - Processing of Geographic Data/Photogrammetry -Computer Sciences/CAAD. The first part of this paper will give an introduction to the goals and implications of the project by comparing it with a similar project one of the authors took part in as a student. Then the paper gives a brief description of the work of the three groups involved, an overview of the methods they employed and the results that were achieved. The main focus will be on the work of the CAAD group . Finally some conclusions are drawn and problems are discussed. The future work includes the testing of the tool by students during the winter term 1993/94.

title	A Tool for Conceptual Design Evaluation Based on Compliance with Site-Development Briefs and Related Planning Regulations
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
doi	https://doi.org/10.52842/conf.ecaade.1993.x.c6i
summary	The need has been established for a computer based decision support tool to use during the conceptual stages of architectural design. The main functions are to check design compliance with the requirements of local planning authorities; characteristics evaluated will include building size, height, plot ratios, circulation and accessibility, and the preservation of natural features on site. This tool is being developed to operate under AutoCAD environment; the construction industry standard computer aided design software, following standard layering convention, integrated command lines, and pull-down menus. In addition to the common graphical output; i.c. plans, elevations and three dimensional models, it will generate textual analysis in report format to use as part of the Environmental Impact Analysis of proposed development. The tool's functions will be based upon the result of two types of field studies. First, interviews and questionnaires will be carried out with architects and planners of both private and public sectors. These will cover issues related to the performance of Computer Aided Architectural Design applications with regard to the evaluation of design schematics, and decision-making for the production of data for environmental statements. Second, field observation and participation will be carried out to observe decision-makers behaviour during assessment of building design proposals. A prototype is currently under development and will be tested against the expectations of the tool designer, Ashraf Ismail, and a team of professionals to be involved in the field studies. A critical analysis of the prototype design methodology and the study findings will be documented in the research thesis to be presented in June 1995.

summary	People’s voluntary movement through an environment is essential for their comprehension of three dimensional space. It may be hypothesized that they move and look around in order to pick up wanted information at the time. This study investigated the following more specific hypotheses by an experiment using a user-controlled space-sequence simulator and the analysis of the subjects’ behavioral data recorded by the simulation system: (1) The strategy of visual search behavior (body movement and viewing direction) is influenced by spatial structure (form and organization). (2) The strategy can be explained by the amount of visual information in the environment, i.e., people move and look in a certain direction in order to maximize effective information at a given moment and position. - If these hypotheses are supported, we can predict people’s behavior in an unfamiliar place on the basis of the spatial structure.

title	Toward a procedure of computer simulation in the restoration of historical architecture
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	In the field of architectural design, “visualization¨ generally refers to some media, communicating and representing the idea of designers, such as ordinary drafts, maps, perspectives, photos and physical models, etc. (Rahman, 1992; Susan, 2000). The main reason why we adopt visualization is that it enables us to understand clearly and to control complicated procedures (Gombrich, 1990). Secondly, the way we get design knowledge is more from the published visualized images and less from personal experiences (Evans, 1989). Thus the importance of the representation of visualization is manifested.Due to the developments of computer technology in recent years, various computer aided design system are invented and used in a great amount, such as image processing, computer graphic, computer modeling/rendering, animation, multimedia, virtual reality and collaboration, etc. (Lawson, 1995; Liu, 1996). The conventional media are greatly replaced by computer media, and the visualization is further brought into the computerized stage. The procedure of visual impact analysis and assessment (VIAA), addressed by Rahman (1992), is renewed and amended for the intervention of computer (Liu, 2000). Based on the procedures above, a great amount of applied researches are proceeded. Therefore it is evident that the computer visualization is helpful to the discussion and evaluation during the design process (Hall, 1988, 1990, 1992, 1995, 1996, 1997, 1998; Liu, 1997; Sasada, 1986, 1988, 1990, 1993, 1997, 1998). In addition to the process of architectural design, the computer visualization is also applied to the subject of construction, which is repeatedly amended and corrected by the images of computer simulation (Liu, 2000). Potier (2000) probes into the contextual research and restoration of historical architecture by the technology of computer simulation before the practical restoration is constructed. In this way he established a communicative mode among archeologists, architects via computer media.In the research of restoration and preservation of historical architecture in Taiwan, many scholars have been devoted into the studies of historical contextual criticism (Shi, 1988, 1990, 1991, 1992, 1995; Fu, 1995, 1997; Chiu, 2000). Clues that accompany the historical contextual criticism (such as oral information, writings, photographs, pictures, etc.) help to explore the construction and the procedure of restoration (Hung, 1995), and serve as an aid to the studies of the usage and durability of the materials in the restoration of historical architecture (Dasser, 1990; Wang, 1998). Many clues are lost, because historical architecture is often age-old (Hung, 1995). Under the circumstance, restoration of historical architecture can only be proceeded by restricted pictures, written data and oral information (Shi, 1989). Therefore, computer simulation is employed by scholars to simulate the condition of historical architecture with restricted information after restoration (Potier, 2000). Yet this is only the early stage of computer-aid restoration. The focus of the paper aims at exploring that whether visual simulation of computer can help to investigate the practice of restoration and the estimation and evaluation after restoration.By exploring the restoration of historical architecture (taking the Gigi Train Station destroyed by the earthquake in last September as the operating example), this study aims to establish a complete work on computer visualization, including the concept of restoration, the practice of restoration, and the estimation and evaluation of restoration.This research is to simulate the process of restoration by computer simulation based on visualized media (restricted pictures, restricted written data and restricted oral information) and the specialized experience of historical architects (Potier, 2000). During the process of practicing, communicates with craftsmen repeatedly with some simulated alternatives, and makes the result as the foundation of evaluating and adjusting the simulating process and outcome. In this way we address a suitable and complete process of computer visualization for historical architecture.The significance of this paper is that we are able to control every detail more exactly, and then prevent possible problems during the process of restoration of historical architecture.

title	An Electronic Tool for Urban Design Analysis
source	Education and Practice: The Critical Interface [ACADIA Conference Proceedings / ISBN 1-880250-02-0] Texas (Texas / USA) 1993, pp. 77-85
doi	https://doi.org/10.52842/conf.acadia.1993.077
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.

summary	This paper describes our current work in the development of an interactive, collaborative design space. It attempts to anticipate a future in which complex design Problems are undertaken by an interdisciplinary, collaborative group of contributors working within an electronic, networked environment. These networked working groups are made possible by the expanded use of high-speed digital networks and are expected to continue to grow within the design profession Using the design of an academic building as a case study, several new tools and techniques were used to develop an information place superimposed over the three-dimensional digital model of the site and proposed building. These tools allow the user to create a collection of data including site documentation and analysis; propose interventions; and access the data through three-dimensional icons in the modeL Several new techniques related to collecting and accessing information within the collaborative space are discussed.

source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 543-555
summary	A comprehensive method for identifying the impacts on solar access of large scale architectural projects still continues to be an important and controversial area in city planning and urban design. Previous research studies such as the Sun Wind and Pedestrian Comfort, a study of Toronto's Central Area, demonstrated approaches possible when dealing with solar issues related to urban design. Existing techniques for solar inventory, analysis and evaluation, while effective, are often dependent on single event analysis (shadow casting) or manual procedures that are time consuming and exceedingly complex especially when needed for day-to-day use by planners or architects involved in complex urban projects. The Centre for Landscape Research has undertaken as part of its research to develop a computational approach that would help city urban designers evaluate and represent the issues of solar access in an urban setting. This paper will outline a series of computational methods developed to utilize an existing municipal digital data base and to describe complex issues of solar access in terms of urban form and context. A technique will be described that quantitatively assesses the total solar potential of a site as compared to changes in solar access due to different urban design proposals. Two-, three- and four-dimensional representation techniques are developed to facilitate understanding of the analysis to users such as city officials, the public, developers, etc.

title	An integrated system to aid the planning of concrete structures: introducing the system
source	The Int. Journal of Construction IT1(2), pp.1-14
summary	This paper reports on the development at Loughborough University of a CAD-based integrated model to aid the planning of in-situ concrete structures. The system development started after a review of the planning models currently available and after a detailed questionnaire survey undertaken amongst the top UK and US contractors on the current status of planning techniques and information technology. The main aim of this system is to automate the planning process of in-situ concrete structures using data generated by CAD systems. So far, the integration of a CAD system (AutoCAD 10) and a computerized scheduling system (Artemis 2000) has been achieved on a typical IBM-PC. This enables the generation of network plans using AutoCAD which are then automatically transferred to the Artemis system for time and cost analyses.Traditionally, construction planners are faced with many conventional drawings and documents which are used to re-extract information relevant to their planning processes. Such an approach can be very inefficient as it involves data double-handling and is often error prone. In addition, current computerized construction planning applications are little more than the automation of manual formulations of plans. For example, data are fed into the planning system and computations are performed using either CPM (Critical Path Method) or PERT (Programme Evaluation and Review Technique). However, data relating to the planning process such as activity lists, resources requirements and durations are not automatically generated within the system. It would thus seem logical to devise a CAD-based integrated planning model which accepts data in its electronic format and involves some integration of the traditional planning approach. This paper introduces the proposed CAD-based integrated planning model and describes its different components. In addition, it discusses the system functional specifications and summarizes the main benefits and limitations of such a model.

title	CAD geometry data exchange using STEP
source	Berlin: Springer-Verlag
summary	With increasing demand for data exchange in computer integrated manufacturing, a neutral connection between dissimilar systems is needed. After a few national and European attempts, a worldwide standardization of product data has been developed. Standard ISO 10303 (STEP - STandard for Exchange of Product data) produced in its first version those parts that are relevant for CAD geometrical data. A European consortium of 14 CAD vendors and users was supported by the ESPRIT programme to influence the emerging standard and implement early applications for it. Over the years 1989-1992, project CADEX (CAD geometry data EXchange) worked out application protocols as a contribution to STEP; developed a software toolkit that reads, writes, and manipulates STEP data; and, based on this toolkit, implemented data exchange processors for ten different CAD and FEA systems. This book reports the work done in project CADEX and describes all its results in detail.

title	A Tool for Typological Analysis
source	[eCAADe Conference Proceedings] Eindhoven (The Netherlands) 11-13 November 1993
doi	https://doi.org/10.52842/conf.ecaade.1993.x.q0g
summary	Any design problem is faced drawing from the architect's knowledge both case knowledge and general knowledge. One type of the latter is abstracted from a multiplicity of cases of which the common features are recognised in such a way as to single out a prototype representing in the best way a class of architectural objects. If applied to a set of residential buildings and to the flats in them the analysis is typological and it is one of the fundamental ways of acquiring general knowledge to be used to face design problems. The tool we present is aimed at such a type of analysis and is based on the idea that it possible to acquire qualitative knowledge through the statistical analysis of measurable characteristics of the examined architectural objects. It has been tested by applying it to the typological analysis of a set of flats of illegal buildings in Sicily. The procedure is organised in two main phases. The first one consists in a series of elaborations performed during the reading of architectural organism; the second one consists in a series of statistical analyses on the results (characteristic variables) of the first.

summary	Everybody who has read his Gordon Cullen or his Edmund H. Bacon knows that movement has long been recognized as a factor in environmental planning in many ways. For example, in the traditional Japanese promenade garden the importance of movement has always been appreciated. The promenader gains an intense experience of the succession, variation and rhythm of the surrounding scene. The spaces and paths lead him from one stage to another. The spatial structure of the Japanese promenade garden, as well as of traditional Japanese architecture in general, is joined most intensively to time and motion. The environment is in relation to the flow of change in many sense, both concretely and existentially. Taking an example of western urban environment. Here perhaps the most marked sequential spaces are to be found in small medieval, mediterranean towns. Thanks to their organic growth, narrow and winding streets and the emphasis on public squares, most of them provide exciting experiences if the observer is only interested in seeing the townscape from the point of view of movement. There are also examples of this kind of environment in Finland. In old wooden towns like Porvoo and Rauma one can still find varied and rhythmic streetscapes and networks of streets and squares, together with a human scale and an almost timeless atmosphere. One could say that such an opportunity to experience spaces sequentially, or as serial visions, is an important dimension for us, especially as pedestrians. And as Gordon Cullen has shown there is in any urban environment much scope to heighten this experience. For example, by creating a sense of ’entering in’ some place, ’leaving for’, ’moving towards’, ’turning into’, ’walking through’ some place or ’following on’ the flow of spaces. Or, as Edmund H. Bacon has said, the departure point of good town planning should be that the successive towns spaces give rise to a flow of harmonic experiences: present experiences merge with earlier ones and become a step towards a future. Or, again in the words of Donald Appleyard, Kevin Lynch and John R. Myer: “The experience of a city is basically of a moving view, and this is the view we must understand if we wish to reform the look of our cities”.

title	Thonet Chairs Design Grammar: a Step Towards the Mass Customization of Furniture
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 181-200.
summary	The paper presents the first phase of research currently under development that is focused on encoding Thonet design style into a generative design system using a shape grammar. The ultimate goal of the work is the design and production of customizable chairs using computer assisted tools, establishing a feasible practical model of the paradigm of mass customization (Davis, 1987). The current research step encompasses the following three steps: (1) codification of the rules describing Thonet design style into a shape grammar; (2) implementing the grammar into a computer tool as parametric design; and (3) rapid prototyping of customized chair designs within the style. Future phases will address the transformation of the Thonet’s grammar to create a new style and the production of real chair designs in this style using computer aided manufacturing. Beginning in the 1830’s, Austrian furniture designer Michael Thonet began experimenting with forming steam beech, in order to produce lighter furniture using fewer components, when compared with the standards of the time. Using the same construction principles and standardized elements, Thonet produced different chairs designs with a strong formal resemblance, creating his own design language. The kit assembly principle, the reduced number of elements, industrial efficiency, and the modular approach to furniture design as a system of interchangeable elements that may be used to assemble different objects enable him to become a pioneer of mass production (Noblet, 1993). The most paradigmatic example of the described vision of furniture design is the chair No. 14 produced in 1858, composed of six structural elements. Due to its simplicity, lightness, ability to be stored in flat and cubic packaging for individual of collective transportation, respectively, No. 14 became one of the most sold chairs worldwide, and it is still in production nowadays. Iconic examples of mass production are formally studied to provide insights to mass customization studies. The study of the shape grammar for the generation of Thonet chairs aimed to ensure rules that would make possible the reproduction of the selected corpus, as well as allow for the generation of new chairs within the developed grammar. Due to the wide variety of Thonet chairs, six chairs were randomly chosen to infer the grammar and then this was fine tuned by checking whether it could account for the generation of other designs not in the original corpus. Shape grammars (Stiny and Gips, 1972) have been used with sucesss both in the analysis as in the synthesis of designs at different scales, from product design to building and urban design. In particular, the use of shape grammars has been efficient in the characterization of objects’ styles and in the generation of new designs within the analyzed style, and it makes design rules amenable to computers implementation (Duarte, 2005). The literature includes one other example of a grammar for chair design by Knight (1980). In the second step of the current research phase, the outlined shape grammar was implemented into a computer program, to assist the designer in conceiving and producing customized chairs using a digital design process. This implementation was developed in Catia by converting the grammar into an equivalent parametric design model. In the third phase, physical models of existing and new chair designs were produced using rapid prototyping. The paper describes the grammar, its computer implementation as a parametric model, and the rapid prototyping of physical models. The generative potential of the proposed digital process is discussed in the context of enabling the mass customization of furniture. The role of the furniture designer in the new paradigm and ideas for further work also are discussed.
