title Roles for Computing in Schools of Architecture and Planning
source Journal of Architectural Education, Sep. 94, pp. 56-64
summary A successful effort to incorporate computing in a school of architecture and planning must satisfy varying student objectives and encompass a range of computing roles. This article reviews these roles and presents a case study of computing at the College of Architecture and Planning (formerly Environmental Design) at the University of Colorado at Boulder. Three categories of instruction make up the curriculum: Tool-using courses teach specific applications, tool-building courses focus on developing new design software, and design theory and methods courses provide rationale for specific computational approaches. Finally, strategies employed in developing this curriculum are discussed.

title Geographical Information Systems and Decision Support for Envi-ronmental Management
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary The growing requirement for spatial decision support systems in Urban and Regional Management is pointed out. This has come about due to the increasing complexity of modern human activities, the increase in awareness of the negative consequences of mankind's technological development on the environment, and also due to the need to respect new regulations and legislation regarding environmental impacts. Such spatial decision support systems need to manipulate and analyze a wide variety of spatially referenced information, frequently in large quantities. Geographical Information Systems are now the chosen means for supporting such information, but in order to arrive at decisions further analysis modules and decision aids frequently need to be linked to them, or integrated with them. Linking multicriteria decision aid with spatial analysis is one way in which spatially referenced information can be used to arrive at decisions in situations where there are many and conflicting criteria. Examples of applications of these ideas to real management problems, including waste management, river management and site management are used to show how spatial information can now be manipulated to aid decisions, and to arrive at some of the design requirements for more flexible and applicable decision support systems. The merits and disadvantages of several different approaches to design and implementation of decision support systems, especially from the users point of view, are discussed.

title A Hypermedia Model for Supporting Energy Design in Buildings
source Reconnecting [ACADIA Conference Proceedings / ISBN 1-880250-03-9] Washington University (Saint Louis / USA) 1994, pp. 39-49

summary Several studies have discussed the limitations of the available CAAD tools and have proposed solutions [Brown and Novitski 1987, Brown 1990, Degelman and Kim 1988, Schuman et al 1988]. The lack of integration between the different tasks that these programs address and the design process is a major problem. Schuman et al [1988] argued that in architectural design many issues must be considered simultaneously before the synthesis of a final product can take place. Studies by Brown and Novitski [1987] and Brown [1990] discussed the difficulties involved with integrating technical considerations in the creative architectural process. One aspect of the problem is the neglect of technical factors during the initial phase of the design that, as the authors argued, results from changing the work environment and the laborious nature of the design process. Many of the current programs require the user to input a great deal of numerical values that are needed for the energy analysis. Although there are some programs that attempt to assist the user by setting default values, these programs distract the user with their extensive arrays of data. The appropriate design tool is the one that helps the user to easily view the principal components of the building design and specify their behaviors and interactions. Data abstraction and information parsimony are the key concepts in developing a successful design tool. Three different approaches for developing an appropriate CAAD tool were found in the literature. Although there are several similarities among them, each is unique in solving certain aspects of the problem. Brown and Novitski [1987] emphasize the learning factor of the tool as well as its highly graphical user interface. Degelman and Kim [1988] emphasize knowledge acquisition and the provision of simulation modules. The Windows and Daylighting Group of Lawrence Berkeley Laboratory (LBL) emphasizes the dynamic structuring of information, the intelligent linking of data, the integrity of the different issues of design and the design process, and the extensive use of images [Schuman et al 19881, these attributes incidentally define the word hypermedia. The LBL model, which uses hypermedia, seems to be the more promising direction for this type of research. However, there is still a need to establish a new model that integrates all aspects of the problem. The areas in which the present research departs from the LBL model can be listed as follows: it acknowledges the necessity of regarding the user as the center of the CAAD tool design, it develops a model that is based on one of the high level theories of human-computer interaction, and it develops a prototype tool that conforms to the model.

title What's Real About Virtual Reality
source IEEE Computer Graphics and Applications, Vol. 19, no. 6, Nov/Dec, 27
summary As is usual with infant technologies, the realization of the early dreams for VR and harnessing it to real work has taken longer than the wild hype predicted, but it is now happening. I assess the current state of the art, addressing the perennial questions of technology and applications. By 1994, one could honestly say that VR "almost works." Many workers at many centers could doe quite exciting demos. Nevertheless, the enabling technologies had limitations that seriously impeded building VR systems for any real work except entertainment and vehicle simulators. Some of the worst problems were end-to-end system latencies, low-resolution head-mounted displays, limited tracker range and accuracy, and costs. The technologies have made great strides. Today one can get satisfying VR experiences with commercial off-the-shelf equipment. Moreover, technical advances have been accompanied by dropping costs, so it is both technically and economically feasible to do significant application. VR really works. That is not to say that all the technological problems and limitations have been solved. VR technology today "barely works." Nevertheless, coming over the mountain pass from "almost works" to "barely works" is a major transition for the discipline. I have sought out applications that are now in daily productive use, in order to find out exactly what is real. Separating these from prototype systems and feasibility demos is not always easy. People doing daily production applications have been forthcoming about lessons learned and surprises encountered. As one would expect, the initial production applications are those offering high value over alternate approaches. These applications fall into a few classes. I estimate that there are about a hundred installations in daily productive use worldwide.

title First Drawings, Then Semantics
source Reconnecting [ACADIA Conference Proceedings / ISBN 1-880250-03-9] Washington University (Saint Louis / USA) 1994, pp. 13-26
doi https://doi.org/10.52842/conf.acadia.1994.013
summary The Semantic Modeling Extension (SME) prototype implements a unique approach to integrated architectural CAD that places the drawing act first in the design process. After drawing a design idea using a computer graphic system, the designer interprets the design, providing semantic content to the graphic entities. An interpretation expresses the meaning of the design with respect to a particular issue, such as structural sufficiency, energy consumption, or requirements for egress, and provides reasoning to evaluate the design addressing that issue. A design may have many interpretations to express the multiple issues that are relevant in a design project. The designer may add or delete interpretations of the design as issues change during the course of the project. Underlying the SME prototype are the concepts of form, function and behavior. In the prototype, evaluation of a design is done by deriving behavior from the graphically represented forms and relating the behavior to stated functions or requirements. The concepts of interpretations and form, function and behavior together establish a virtual product model for design. In contrast to component based approaches to product modeling that tightly bind form representations to their behavior and function, a virtual product model allows the designer to manipulate the relations among these three descriptors of a design, and thus manipulate the semantics of the design entities. By distinguishing between the act of proposing a design by drawing the conceived form and the act of assigning meaning to the form, the virtual product model approach supports both graphic thinking for design synthesis and symbolic reasoning for design evaluation. This paper presents a scenario of the use of the SME prototype in building design; provides an analysis of the design process and computational support described in the scenario; contrasts a virtual product model approach with a component-oriented product model approach; describes the software implementation of SME; and presents implications and conclusions regarding design process and technical integration.

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 Identification And Analysis of the Recreational Behaviour Forms and the Needed Recreational Space Using the Integrated Spatial and Object-Oriented Gis: Concepts and Statements
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary This paper is concerned with how to measure and investigate changes in the recreational behaviour and the required recreational space in Polish seaside recreational areas in last few years. Spatial information is an integral part of the identification and analysis of recreational behaviour and required recreational space. We postulate, therefore, that spatial information should be fully incorporated in integrated object-oriented GIS and Decision Support Technology. We argue in this paper that the existing theoretical approaches with their descriptive and technical basis do not offer directions for its application and evaluation. They do not seek to explain the processes undergone by spatial information, nor define appropriate data models. New approaches to GIS use object-oriented structures and expert systems concepts, and they will become increasingly helpful in understanding GIS. It is not unreasonable to expect that the most important issue is to use a data model or object-oriented models which closely represent the user's concept of the geographic object for representing spatial phenomena. We have discovered that most Polish users in this field are unable to collect the data they require directly. Thus they have to use methods and techniques, which cannot be found in GIS such as SWOT analysis. According to our experiences, the identification and analysis of the recreational behaviour and the required recreational space should be defined as a system approach where: (i) recreational space requires an object, (ii) state of recreational space is defined by the set of values of recreational space features, and (iii) the utility of the recreational space is defined by a set of features. The identification and analysis of the recreational behaviour in the presented approach are based on the features/utilities matrix of the recreational space and the computer map. The development of such a system needs many organizational changes. It is shown that in many applications organizational rather than the technical aspects of GIS determine their future and open the way to new spatial analytical techniques.

title A Functional Framework For Conceptual Modelling
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary A conceptual model is not only indispensable for the design and implementation of knowledge based systems, but also for their validation, modification, maintenance and enhancement. Experience indicates, however, that in many cases reality is not well reflected in a full-fledged conceptual model. What is systematically lacking in the prevailing conceptualization methods is a well-developed theory of knowledge that underlies conceptualization methods: a theory that precedes the process of forming meaningful classifications and that precedes the specification of a conceptual model. To date, conceptualization methods are based on the probabilistic assumption that, in essence, all conditions necessary for creating a classification, are provided initially and can easily be revealed by utilizing mathematical measures of similarity. Another frequently occurring prototypical assumption is that for creating a classification, necessary conditions are sufficient. Furthermore, it is assumed that the categories of conditions are a priori fixed and unconditional. That conceptualizing takes place without any explicit background knowledge about goals of classifications and without contextual influences and that categorizations have an unconditional status are not viewed as problems. In contrast to these approaches, the functional view states that relevant descriptive attributes are not necessarily a priori given but should be acquired through knowledge about goals of classifications and about contexts. It is also asserted that an explicit concern for necessary conditions will not suffice for capturing the dynamics of reality. Furthermore, the functional view puts forward that a goal- and context-oriented strategy leads to the reconstruction of new attributes and categorizations with a dynamic status. The aim of this paper is to discuss the theoretic and practical merits of the functional view compared to the probabilistic and prototype approaches. Conceptual models developed in the Computer Integrated Manufacturing-Project will serve as illustrations for the main ideas.

title Maximising the Benefits of CAD Systems in Architectural Education
source The Virtual Studio [Proceedings of the 12th European Conference on Education in Computer Aided Architectural Design / ISBN 0-9523687-0-6] Glasgow (Scotland) 7-10 September 1994, p. 228

summary The positive impact of Computer Aided Design (CAD) in professional architectural practice has been in focus in recent times but relatively little has been written on its significance in the education of the contemporary architect. It is common knowledge that the profession of architecture is currently undergoing enormous strains as it battles to keep abreast of trends and developments in a period of series of rapid advancement in science, technology and management (RIBA, 1992). Whilst attempts are being made to redress the shortcomings of the profession in the above context, the requirements for architectural education are yet to forge a coherent strategy for the implementation of CAD/IT in the curriculum of schools of architecture. In almost every other field, including engineering, medicine and the humanities, computing application to problem-solving and decision-making is seen as a way forward as we move into 21st century. Architectural education must integrate CAD/IT into the teaching of core modules that give the architect distinctive competence: studio design. That is one of the best ways of doing justice to the education of the architect of today and the future. Some approaches to the teaching of CAD in schools of architecture have been touched upon in the recent past. Building upon this background as well as an understanding of the nature of design teaching/learning, this paper examines ways of maximising the benefits of CAD systems in architectural education and of bringing computer aided designing into the studio not only to enhance design thinking and creativity but also to support interactive processes. In order to maximise or optimise any function, one approach is to use the hard systems methodology which utilises analytic, analogic and iconic models to show the effect of those factors which are significant for the purposes being considered. The other approach is to use the soft systems methodology in which the analysis encompasses the concept of a human activity system as a means of improving a situation. The use of soft systems methodology is considered more appropriate for dealing with the problem of design which is characterised by a flux of interacting events and ideas that unroll through time. The paper concludes that the main impediment to maximising the benefits of CAD systems in architectural education is not only the inappropriate definition of the objectives for the implementation of CAD education but also that the control subsystems are usually ill-structured and relatively poorly defined. Schools must attempt to define a coherent and consistent policy on the use of CAD systems as an integral part of studio design and evolve an in-house strategic and operational controls that enable the set objectives to be met. Furthermore, it is necessary to support the high level of productivity from CAD systems with a more efficient management system, especially in dealing with communication, data sharing via relational database, co-ordination and integration. Finally, the use of soft systems methodology is recommended as the way forward to optimising CAD systems in design education as it would provide continuous improvements while maintaining their productive value.

title Navigation in Spatial Information Environments: User Interface Design Issues for Hypertext and VR Systems Posters
source Proceedings of the ECHT'94 European Conference on Hypermedia Technologies 1994
summary The Information City project (presented in a poster at Hypertext 93) uses the spatial user interface metaphor of a city to organize and navigate large collections of hypertextual information. As we are used to navigate real life cities the city metaphor -- enriched with magic features -- should help to navigate information structures. A first implementation of the Information City was started in a MUD system. MUDs are networked multi-user text-adventure games which usually make use of a house / city metaphor. MUDs are conceptually similar to hypertext systems and navigational findings in those systems are therefore relevant also to hypertext. While implementing the first parts of the city research into navigation in MUDs was found necessary. This poster presents some results of this navigational study and describes how knowledge in the domains of architecture and city-planning can be used to design an easy to navigate virtual city. Highlights of the results concern magic features and collaboration. Magic features extend the spatial metaphor beyond typical properties of space. An example is the hypertext link which allows tunneling through the spatial structure. Other results concern the richness of spaces (or space-descriptions) and communication between users. It seems the chief benefit of the spatial metaphor of the city is in communication about spatial relationships of information. The findings probably are valuable in designing any information system using spatial metaphors. They are especially useful for hypertext systems realized in some virtual environment -- be it a MUD or an immerse virtual reality system.

source Computer Graphics and Applications, Vol. 14, No. 1, January 1994
summary We survey European activities in virtual reality, with an emphasis on selected efforts in architecture and sound, telepresence, scientific visualization, simulation, software design, and entertainment. This article surveys European activities and funding for VR with two caveats: First, nearly a year separates writing and publication. For most scientific fields, this publication delay for survey material would be minimal: for virtual reality, significant changes might have since occurred in some programs. We took advantage of the revision period to upgrade our information and the references as much as possible. Second, some long standing, significant European efforts go unmentioned as outside the scope of our short survey or as duplicates of others included. Despite the limitations, this sampling of Europe's leading efforts collectively gives an accurate snapshot of current European activity.

summary Twenty years of revolution, from the middle '70 to the middle '90. Many things have changed since the origins of computer graphics and computer aided design in architecture. We started teaching drafting on terminals which connected to mini computers, complex procedures or sets of graphics libraries working with keywords, vectors and storage screens. The next step was devoted to the discovery of workstations in the early '80's, where the user sat face on to the whole power of a multitasking system. At that time to use up to 16 time sharing processes running on the same work station seemed to have no practical use at all. Fortunately someone (ie Xerox PARC laboratories) at the same time started to develop the so-called GUI. Graphical user interface started a revolution in human/machine interface (ie Smalltalk). The desktop metaphor, the use of multiple windows and dialogues joined with icons and pop up menus let the user manage more applications and, even more important, created a standard in application/user interface (CUA). In the meantime focus had moved from hardware to software, systems being chosen from the software running. The true revolution we have seen starting from that base and involving an ever increasing number of users was the birth of PC based applications for CAAD. Generally speaking nowadays there are three main technologies concerning teaching: communication, multimedia and virtual reality. The first is the real base for future revolution. In the recent past we have started to learn how to manage information by computers. Now we can start to communicate and share information all over the world in real time. The new age opened by fax, followed by personal communication systems and networks is the entry point for a real revolution. We can work in the virtual office, meet in virtual space and cooperate in workgroups. ATM and ISDN based teleconferencing will provide a real working tool for many. The ever increasing number of e-mail addresses and network connections is carrying us towards the so called 'global village'. The future merger between personal digital assistant and personal communication will be fascinating. Multi & HyperMedia technology is, like a part of VR, a powerful way to share and transfer information in a structured form. We do not need to put things in a serial form removing links because we can transfer knowledge as is. Another interesting and fundamental aspect typical of VR applications is the capability to change cognitive processes from secondary (symbolic - reconstructive) to primary (perceptive - motory). In this way we can learn by direct experience, by experiment as opposed to reading books. All these things will affect not only ways of working but also ways of studying and teaching. Digital communications, multimedia and VR will help students, multimedia titles will provide different kinds of information directly at home using text, images, video clips and sounds. Obviously all those things will not substitute human relationship as a multimedia title does not compete against a book but it helps.

summary This paper describes a physically-based rendering system tailored to the demands of lighting design and architecture. The simulation uses a light-backwards ray-tracing method with extensions to efficiently solve the rendering equation under most conditions. This includes specular, diffuse and directional-diffuse reflection and transmission in any combination to any level in any environment, including complicated, curved geometries. The simulation blends deterministic and stochastic raytracing techniques to achieve the best balance between speed and accuracy in its local and global illumination methods. Some of the more interesting techniques are outlined, with references to more detailed descriptions elsewhere. Finally, examples are given of successful applications of this free software by others.

title The comparison of animation, virtual reality, and scenario scripting in design process
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 Design media is a fundamental tool, which can incubate concrete ideas from ambiguous concepts. Evolved from freehand sketches, physical models to computerized drafting, modeling (Dave, 2000), animations (Woo, et al., 1999), and virtual reality (Chiu, 1999; Klercker, 1999; Emdanat, 1999), different media are used to communicate to designers or users with different conceptual levels¡@during the design process. Extensively employed in design process, physical models help designers in managing forms and spaces more precisely and more freely (Millon, 1994; Liu, 1996).Computerized drafting, models, animations, and VR have gradually replaced conventional media, freehand sketches and physical models. Diversely used in the design process, computerized media allow designers to handle more divergent levels of space than conventional media do. The rapid emergence of computers in design process has ushered in efforts to the visual impact of this media, particularly (Rahman, 1992). He also emphasized the use of computerized media: modeling and animations. Moreover, based on Rahman's study, Bai and Liu (1998) applied a new design media¡Xvirtual reality, to the design process. In doing so, they proposed an evaluation process to examine the visual impact of this new media in the design process. That same investigation pointed towards the facilitative role of the computerized media in enhancing topical comprehension, concept realization, and development of ideas.Computer technology fosters the growth of emerging media. A new computerized media, scenario scripting (Sasada, 2000; Jozen, 2000), markedly enhances computer animations and, in doing so, positively impacts design processes. For the three latest media, i.e., computerized animation, virtual reality, and scenario scripting, the following question arises: What role does visual impact play in different design phases of these media. Moreover, what is the origin of such an impact? Furthermore, what are the similarities and variances of computing techniques, principles of interaction, and practical applications among these computerized media?This study investigates the similarities and variances among computing techniques, interacting principles, and their applications in the above three media. Different computerized media in the design process are also adopted to explore related phenomenon by using these three media in two projects. First, a renewal planning project of the old district of Hsinchu City is inspected, in which animations and scenario scripting are used. Second, the renewal project is compared with a progressive design project for the Hsinchu Digital Museum, as designed by Peter Eisenman. Finally, similarity and variance among these computerized media are discussed.This study also examines the visual impact of these three computerized media in the design process. In computerized animation, although other designers can realize the spatial concept in design, users cannot fully comprehend the concept. On the other hand, other media such as virtual reality and scenario scripting enable users to more directly comprehend what the designer's presentation.Future studies should more closely examine how these three media impact the design process. This study not only provides further insight into the fundamental characteristics of the three computerized media discussed herein, but also enables designers to adopt different media in the design stages. Both designers and users can more fully understand design-related concepts.

title Communicative Acts in Cooperative Architectural Design Environments
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary The purpose of this paper is to present a scheme, that can be used to support the communication process in cooperative design. Computational aids for design have largely been for a designerworking by himself/herself. These aids have also been supplemented by the widespread use of artificial intelligence approaches. However, design is so complex, and very rarely acted upon by a single designer but many more working towards the same aim. This involves a new paradigm in which designers need to cooperate with each other using a computational medium. A protocol analysis in cooperative design has been carried out and technological support has been proposed.Cooperative design becomes an important paradigm for the next generation of intelligent computer aided design systems. It will be conducted in many forms among several designers and willrequire the support of advanced communication facilities beyond the "passive" transmission of data and messages. Technological advances in communication networks have opened up new ways for cooperative design interaction across several processes of cooperation among designers, designers and computer aided design systems, computer aided design systems and knowledge based systems, and knowledge based systems themselves. In cooperative design environments, aunit of communication among designers is the transfer of a message from one designer (a sender) to another (a receiver). The aim of such communication is to provide the receiver with some information or to have the receiver take certain actions. Inspired by the speech act theory, a branch of the philosophy of language and linguistics, such a unit is called a communicative act. By analogy to architectural design, a communicative act is a performing act in designers communication.

title GIS: Science or Tool - The Built Environment Perspective
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary This paper attempts to locate GIS in the context of the built environment professions, rather than in the context of computer science, recognizing the integrated but limiting approach of viewingGIS from a strictly computer / spatial science perspective. The paper reviews the conflicts and tensions appearing in the GIS debate seeing them as reflecting the differences between the perceptions and interests of software developers and those of the professions. The "spatial science versus professional tool" dilemma is therefore critically assessed. Science is identified as the dominant paradigm within which GIS development has taken place. This encompasses the emphasis on GIS as spatial science; the interest in particular forms of spatial analysis; a narrow approach to the idea of information; the debate about the appropriate emphasis on the location for GIS in undergraduate education. The interests and activities of the professions cannot be encompassed within the pre-existing science paradigm. The paper identifies the interest the professions have had in broad geographical issues (as distinct from narrow spatial issues). It recognizes the different conventions and procedures used in recording and using geographical information, not all of them objective or scientific. It views the computer, not as a "scientific engine", but as a modern medium for representing and analyzing information. This includes storage and analysis, both internally (algorithmic manipulation) and outside (qualitative manipulation, beyond formal -"computer"- logic). This approach suggests a framework for research of a nature more sympathetic to the needs of the built environment professions in particular and an agenda which would include an examination of: (i) the conventions and procedures used in the professions to collect, store and process information and how these translate to computer technology; (ii) the types of software used and the way procedures may be accommodated by combining and integrating packages; (iii) the dynamism of GIS development (terms such as "dedicated", "mainframe", "PC-based", "distributed", "pseudo-", etc. are identified as indicativeof the need for professions-based approaches to GIS development); (iv) a critique of "information" (modelling of information flows within the professions, may yield valuable insights into the (modelling of information flows within the professions , may yield valuable insights into the similarity of requirements for a variety of "workplace scenarios").

title Solving design problems by computational exploration
source J. S. Gero and E. Tyugu (eds), Formal Design Methods for CAD, NorthHolland, Amsterdam, pp. 249-270
summary Most real-world problems, especially design problems, are ill-structured, but formal approaches to problem-solving in AI have only really made progress into techniques for solving well-structured problems. Nevertheless, such research contains clues which illuminate the way towards formal approaches to solving ill-structured problems. This paper presents the foundations of an approach towards developing a better computational understanding of ill-structured problems and how to solve them computationally, with the eventual aim of giving AI problems a much greater and more useful role in the design process. The main issues which come up in this endeavour are the notions of different kinds of ill-structuredness, and the meaning of a 'solution' to an ill-structured (and hence possibly insoluble) problem. Some basic algorithmic recipes are proposed for dealing with the main kinds of ill-structuredness, and the initial design of a general computational technique which deals with general ill-structuredness is discussed.

title Matchmaker: An Instrument for Matching Demand for and Supply of Buildings and Revealing Specific Discrepancies
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary To match supply and demand of buildings, various approaches are possible. While artificial intelligenceis favoured by some, we think that a less 'heavy' approach can be more cost and time efficient. The casewe have chosen to exemplify our approach concerns architectural heritage. To match supply and demandwhile at the same time respecting the constraints imposed by cultural heritage, it is necessary to bringthem together and to effectuate feasibility studies in the shortest possible time. The feasibility study shouldbe served by tools allowing the various partners to communicate on the level of the match between them, translated in terms of spatial organisation and building constraints. In the past years, our designmorphology group has developed and tested a graphic-based reordering tool which has been applied to large governmental buildings, both existing and new. The same tool can be used for weighted objectives ranking and evaluation, to have a synthetic view of the combined basic preferences and differences of the involved parties as for example in a jury wise evaluation and ranking of alternative proposals. The proposed tool is the electronic and graphic version of the data and association matrices, which have been for a long time recommended for use in the preliminary phases of design. But as long as these instruments could only be drawn and redrawn on paper they were much too ineffectual and found little real application. The developed tool is connected by sub-routines to a computer aided design package, within which the spatial patterns are translated into plans and attached data bases. The matching takes place in a number of steps. The first is to describe the organisation (the demanding party) as functional units which can be made corresponding with spatial units. The prescription of spatial needs can take place in both quantitative and qualitative manners. The Matchmaker tools offer the possibility of interactive clustering of spatial needs. Another step, which can be taken concurrently, is to describe the monument in spatial units and distance relationships. The input can be generated directly within the matrix, but it is much easier, more self evident and realistic to generate this automatically from the draughted plan. The following step is the input of constraints originating from heritage preservation objectives, expressed in levels of authorised intervention. Again, the Matchmaker tools offer here the possibility of visual clustering of spatial units, their relationships and associated properties. In the next step, the matching takes place. In this step the actual positions, properties and constraints of existing spaces in the monument are compared (and visualised by discrepancies views) to the optimised and clustered spatial needs of the end user. In the following phase, the feasibility in terms of space, building fabric and costs can be appraised. Once a compromise has been attained, preliminary proposals can be designed and laid down in terms of drawings. The spatialdesigns can then again be translated into matrix views and evaluated.

title Europe '94 - A Visitor's Report on the State of CAAD in Education
source The Virtual Studio [Proceedings of the 12th European Conference on Education in Computer Aided Architectural Design / ISBN 0-9523687-0-6] Glasgow (Scotland) 7-10 September 1994, pp. 262
doi https://doi.org/10.52842/conf.ecaade.1994.x.s5h
summary During May, June and July of this year, I had the pleasure of visiting twelve institutions across Europe where computers are being used in the teaching of Architecture. There are as many different approaches to the incorporation of computers in the curriculum as there are places, and they all have some degree of success. My greatest surprise was the large size of these Schools, even in relatively small countries. Dealing with a huge number of students makes any kind of mandatory computer instruction almost impossible. In spite of all difficulties, enthusiasm and willingness to work directly with students was the single most important characteristic in the faculty and staff who are having the greatest success. Support staff dedicated to the maintenance of equipment and software were provided at most of the institutions. For those who do not have this benefit it is critical to relieve the teaching and research faculty of the need for these time-consuming tasks. Formal research activities are not essential to effective education. The process of setting up such efforts is again a distraction from the more important job of teaching. If research projects grow naturally out of the curriculum, they may be pursued without impeding instruction. Most serious of all, there is a substantial lack of communication and cooperation among these schools, and by implication, among all of the other schools in Europe. The mechanism of annual conferences held by ECAADE is insufficient to exchange information and interests. There were several occasions when I mentioned work that was being carried out at one place that would match very nicely with efforts at another. However, it is clearly impossible for any one school to spearhead this kind of collection and coordination of activities. The only appropriate organisation for this kind of exchange would be a centralised service initiated and maintained by the European Community. It is very important that such a body does not attempt to limit or direct the work of individual schools, rather simply serves as a clearinghouse through which the various groups can benefit from each other's work, to the mutual benefit of all.

title Collaboration and Coordination in Architectural Design: approaches to computer mediated team work
source TeamCAD 97, 17-23
summary In 1993 and 1994, instructors and students of architecture at several universities around the world* collaborated briefly on two "virtual design studio" projects. Using off-the-shelf technology of the time-email, CU-See-Me internet video, international conference calls, and exchange of CAD drawings, images, and Quicktime animations-this ambitious project explored the possibility of bringing together diverse members of an international design team together to collaborate on a short term (two week) project. Central to the "Virtual Design Studio" was a 'digital pinup board', an area where participating designers could post and view drawings and textual comments; video links and email exchange provided the media for direct communication media about designs. A report on the project [21] makes clear that the process was not without technical difficulties: a significant amount of communication concerned scheduling and coordinating file formats; disappointingly little was devoted to discussions of design issues. Although it's clear that many of the minor technical problems that inevitably plague a forward-looking effort like the Virtual Design Studio will be solved in the near term, the project also reveals the need for research on software and design practices to make computer mediated design collaboration realize its attractive promise.
