title	Mastering Urban Network Intersection And Superimposition, in an Object-oriented Knowledge System Integrating Rules, Neurons and Processes
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	Many networks cover the urban texture, either superimposed at a variable distance, or really intersecting, or even in interconnection. We briefly recall the HBDS model, working on persistent abstract data types associated to graphical representations and carrying algorithms expressing conditions to be verified and/or actions to be performed. HBDS is an integrated system too, including database, expert system dealing with fuzzy rules and facts, discrete simulation engine, and neural engine; it has a general purpose programming language. Any urban network is associated to a given prototype, according to the same scheme named prototype with more specific components. These prototypes allow to build the different thematic structures instantiations of the prototypes. All possible cases of arc intersection or "pseudo-intersection" (simple superimposition)or interconnection are obtained by, owing to new prototypes. Moreover, such (pseudo)-intersections are automatically recognized and processed without a human intervention, owing to classes ofconstraints and classes of rules. They deal with particular constraints concerning the location of some urban furniture, and rules concerning the way a cable or a pipe must follow according to thepre-existing other networks in a given area, the minimal distances, minimal or maximal depths, and some required equipments. Urban classes of (pseudo-)intersections inserted in the hyperciass"neuron", inheriting of neural features, may be used for automated learning of urban knowledge; owing to their "behavior", these neurons can communicate and perform actions on other components. Urban classes inserted in the hyperciass "process" may be used for building very large models simulating complex urban phenomenons, thus allowing a better understanding of the real phenomenons. As a conclusion, we emphasize the methodological aspects of object-oriented integration for an efficient processing of the urban context, based on prototyping and mixing rules, neurons and processes.

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.

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	Strategic Decision Support: Using Neural Networks to Enhance and Explore Human Strategizing
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	This paper focuses on a mechanism by which planners and designers are thought to reduce complexity. The mechanism involves choosing a potentially profitable direction of search, or choosing potentially profitable set of aims to pursue, within which a detailed solution might be found, and rejecting all potentially unprofitable directions of search. The literature of psychology, planning and operations research is drawn upon to argue that designers base such initial choice of direction on their candidate aims' relative scores for eight key parameters: probability, returns for effort, delay, robustness, difficulty, present satisfaction and dependence. The paper then describes a piece of decision support software which, by eliciting any user's scores for their candidate aims on the eight key parameters, is able to order such aims into a strategic plan. Such software also incorporates a simulated neural network which attempts to "learn", from users' recorded responses to the software-suggested strategies, how users actually weight the relative importances of the eight key parameters. That is, it is hoped that the neural network will "converge' to some prototypical pattern(s) of weightings. Having such a tool would certainly constitute an advance in the state of the art of computer-aided strategy development. Alternatively, if the network never converges, the use of neural networks in computer-aided planning is perhaps not advisable. Accordingly, a test was conducted in which a group of planners used the software to address a typical spatial problem. The results, in terms of whether or not the neural network converged, will be reported.

title	User Interfaces and Systems for Remote Design Working on ISDN Systems
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	This paper will discuss the requirements and possible configurations of user interfaces suitable for remote working multi-disciplinary design practices. Telecom companies throughout Europe are making heavy investments in digital communication technology (ISDN). The networks being created will form a standard method of high speed data transfer which can be readily accessed by any computer hardware platform. There are great opportunities for remote working by design groups, not simply sharing data but also interactive working and video communications. Digital communications provide the electronic arterial system to the new field of remote computing,whilst cheap and effective hardware and software support systems provide readily usable platforms on which to build remote multi-disciplinary design practices where the exploitation of specialistknowledge and skills is not limited by traditional methods of communication. ISDN networks allow real time video, voice and design software interaction - indeed, everything except the designer's physical presence. However as with all computer technology and indeed communications technology the user interface which gives access and control is vitally important. The user interface should provide the following features: be transparent to the user and simple and reliable to operate; allow an interactive window/s into the remote site's design information whatever the type of application being dealt with; carry out data compression, file transfer and file management procedures with minimum input from the user; cause no conflicts with design software or secondary applications;be able to access different platforms.

title	Maximising the Benefits of CAD Systems in Architectural Education
doi	https://doi.org/10.52842/conf.ecaade.1994.x.u8n
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	Style: Approach From a Cognitive Point of View
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	This research sets up a theory about style from a cognitive point of view. It has been observed that the constant applications of some factors in a design process constitute the formation of a style. Those factors included design constraints, search methods, goals, and the sequential order of applying them. A style may result from certain actions and interactions of these factors. And because of the constant applications of the factors, constant forms by which a style is manifested . The contents of the factors determine the expression of a style which can be imitated and changed from time , whereas the quantities of the factors determine the degree of a style. Thus, this theory provides, explanations about the cause, the degree, the change and the imitation of style.

title	Mapping a Single Data Stream to Multiple Auditory Variables: A Subjective Approach to Creating a Compelling Design
source	Proceedings of the Third International Conferenceon Auditory Display, Santa FO Institute
summary	Representing a single data variable changing in time via sonification, or using that data to control a sound in some way appears to be a simple problem but actually involves a significant degree of subjectivity. This paper is a response to my own focus on specific sonification tasks (Kramer 1990, 1993) (Fitch & Kramer, 1994), on broad theoretical concerns in auditory display (Kramer 1994a, 1994b, 1995), and on the representation of high-dimensional data sets (Kramer 1991a & Kramer & Ellison, 1991b). The design focus of this paper is partly a response to the others who, like myself, have primarily employed single fundamental acoustic variables such as pitch or loudness to represent single data streams. These simple representations have framed three challenges: Behavioral and Cognitive Science-Can sonifications created with complex sounds changing simultaneously in several dimensions facilitate the formation of a stronger internal auditory image, or audiation, than would be produced by simpler sonifications? Human Factors and Applications-Would such a stronger internal image of the data prove to be more useful from the standpoint of conveying information? Technology and Design-How might these richer displays be constructed? This final question serves as a starting point for this paper. After years of cautious sonification research I wanted to explore the creation of more interesting and compelling representations.

title	On the Role of Hypermedia in Architectural Design 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. 115-120
summary	Teaching architectural design is not primarily concerned with presenting a body of knowledge analytically, but rather with influencing the way students act in a design situation. Previous design cases play an important part in this process, as they provide students with sets of objectives and corresponding solution patterns. Nevertheless, one of the main problems with using precedents in the design studio is that students take them rather as models to be copied than as starting points for their own research. To overcome this problem, the representation of design cases has to be improved. Our thesis is that in architectural design the structure of a case base of design precedents relies to a large extent on the various, and often conflicting, interpretations of precedents that are provided by architectural theory and discourse. Within a theory of design where exploration is the dominant strategy, we propose a method of using design cases and design theories in an integrated way. Through the use of hypermedia as a medium for representation of design cases, the process of looking for information can be based on the same metaphor as the design process itself.

title	Sequential and Concurrent Cad Layering
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	Most CAD software allows graphical and text objects to be grouped into layers. There are two fundamentally different methods for layering: sequential layering and concurrent layering. With sequential layering, layers are attributes of the CAD database and objects are attributes of a layer. With concurrent layering, objects are attributes of the CAD database and a layer is an attribute of an object. Sequential layering emulates the pinbar drafting technique. As a result, it is output oriented. Only one layer at a time can be edited. Concurrent layering is uniquely a computer based layering method which has no manual equivalent. User specified sets of layers can be edited concurrently. It makes it possible to organize the infrastructure of the CAD database which equally facilitates input, i.e. editing design information, and output, i.e. presenting construction information on paper. Specification levels are related to design levels and to construction phases. Specification levels can serve as interfaces between input and output. In particular, a concurrently layered CAD database can be structured in layers which conform to specification levels. Furthermore, the layers can be subdivided by sub-system such as construction discipline, and by partial-system such as room finish schedules. It is demonstrated how a concurrently layered environment for computer aided design can be developed which permits deductive and inductive design activities. The appendix provides a detailed example of a concurrently layered CAD file with a default input and output environment of layers and layer groups. The environment was developed to coordinate the design and production activities of an architectural practice. The connections between layers and layer groups are illustrated in a 22 x 32 matrix.

title	Graphic Data Comprehension In Design Thinking
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	There exist several kinds of data qualities when we see a graphic. In such a procedure, we rarely describe all the qualities by language. This is an interesting phenomenon. We are doing something that we understand but we cannot tell when we are thinking or drawing a graphic. A problem like this touches the central point related to the understanding of drawing in design. It is the purpose of this study. A series of experiments is conducted to compare two sets of data: design by drawing and design without drawing. The major result of this experiment is that the type without drawing contains less design contents and is easy to reassemble. The drawing type contains much richer design contents which easily disappeared when reassembled through the descriptions. We believe there exist two major characters of visual data: nameable and unnameable. Nameable data may be designed and communicated without drawing. For the unnameable one, we may proceed when its qualities show out. According to this study, we conclude that the mental representation of visual data is basically prepositional rather than picture-like. But, in design procedures, the picture-like one may appear when the figure comes out of the mental world, with lots of unnameable qualities.

title	An Information Model of Energy Performance in Early Building Design
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	Design is a creative and dynamic process. The level to which a future generation of Intelligent Integrated Building Design Systems will be able to support this process depends on the power of the underlying conceptual models to cover the semantics of design. In the definition of generic building models, the concept of constraints appears to be a powerful means to formalize those semantics. Both design performance goals, and rules and relations in design composition can be described as constraints. The Engineering Data Model (EDM), recently developed at UCLA, acknowledges this fact. It allows the formal definition of object oriented building models, using constraints as the central concept for describing relations. This paper will discuss the development of an EDM building model for the integrated design for energy performance, and the implementa-tion of this model in a small prototype system. We will specifically deal with modelling informati-on in the early design stages. This information typically consists of multiple global design alternatives on one hand, and a wide range of conflicting design goals on the other hand. In the paper, it is demonstrated that integration of these conflicting views on building performance in one coherent model is the key to obtaining an optimal design result. Using the Dutch building codes for energy performance (NEN 2916) as an example of design goals, the concepts and relations of these building codes were translated to a formal EDM model. A small shell was built on top of this computer-interpretable model, to demonstrate the useability of the model during the solving of a concrete design problem. It is shown that the EDM building model is able to provide the designer with integrated information through combining different sets of performance constraints and design alternatives in one environment.

source	Terry Knight, Transformation in Design: A Formal Approach to Stylistic Change and Innovation in the Visual Arts, Cambridge University Press, 1994, 258 p.
summary	Shape grammars are languages of two- and three-dimensional forms analogous to spoken languages. A great deal of attention has been centered on them as a basis for supporting design with computers. They are sets of rules which can be used to create families of visually related designs. Each design, in the family of possible designs that can be created by a set of rules, is generated by successively applying rules from the set to the current state of a design until no more rules are applicable. A rule may be applied if certain shapes specified by the rule exist in the current state of the design. After application of a rule, the specified shapes are substituted with one or more replacement shapes specified by the rule thereby adding, subtracting or modifying shapes in the current design. From a single initial state many alternative designs can be generated because there is usually more than one applicable rule at any stage.

title	Housing Performance, Data Management and Decisionmaking
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	This paper focusses on performance measurement in the framework of the strategic housing management. Reference is made to studies regarding two housing corporations in the Netherlands. The performance measurement is an element in the methodology of intervention planning and market positioning of housing estates. Aside of the measurement of technical and functional performances in this methodology market-technical and price-technical data are processed. These data sets, eventually, can be completed with data of consumer's living appreciation. An insight is acquired based on this methodology in (i) the market position of the estate; (ii) the performances of the dwelling and living environment; (iii) the relative position among estates. Diverse performance aspects and performance levels can be distinguished in the offered representation. The performance measurement is dealt with from 2 angles of incidence (i) from the dwelling and living environment; (ii) from the target group. On the level of the estate the performances are represented in the form of a quality profile. To enable the comparison of performances on the portfolio level a performance-index is developed, a so-called Housing Performance Rate (HPR). The performance measurement on estate and portfolio level is the basis of diverse management decisions, such as quality policy, rent policy, target groups policy and policies concerning neighbourhood management.

title	The Use of Genetic Algorithms in Spatial Optimisation Problems
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	The manipulation of a set of associative data usually involves the search of a huge search-space (e.g. a set of 20 elements can be ordered in 20! ways, which is approximately equal to 2.4e+ 18). Rooms on a floor can be considered as a set of associative data. Optimising such a set according to some criterion (for example, minimising the distance between the related elements) can therefore be a daunting task. In order to assist in this task, a program (called ROP) has been developed, which graphically represents the relations in a matrix. The points in this matrix can be moved manually, thereby transforming the search process into a visual task. However, a considerable amount of skill remains required. In order to further alleviate the user in this task, ROP has been augmented with a Genetic Algorithm. A genetic algorithm is ideally suited to deal with very large search-spaces, and proved to be a valuable addition to ROP. In addition to employing the genetic algorithm for finding the optimal ordering, it can also be made to suggest several different orderings with approximately equal fitness, thereby providing elementary creativity support. The combination of ROP with a genetic algorithm provides a generic tool for the manipulation of all multivariate or associative data sets; in- as well as outside the design realm.

title	Spatial Schemata and Design Competence: A Case of Beginning Designers
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	In the course of learning professional skills in architectural design, students will develop, usually with the help of instructors, certain ways of analyzing spatial relations. Such spatial schemes are considered critical means to the comprehension of the graphical representations of spaces, and therefore schemes of different kind will have different effects on design performance. This study intends to explore this issue. Three sets of experiments are conducted to test our working hypotheses as stated as follows: (i) to reproduce a plane graphic requires knowledge and skills different from those to recognize; (ii) some schemes are more effective than others in reproducing plane graphics; (iii) the kind of schemes that can effectively reproducing given forms (in plane graphics) can also have positive effects on design capabilities. It is interesting to further differenti-ate the kinds of schemes and their power as design tools. All these experiments employ three kinds of spatial schemes: the categorical, the referential, and the hierarchical from the results we can reach the following conclusions: (i) reconstruction is a different mental activity from recognition which is mainly a comparison between the input data and the known characteristics reconstruction relies more on the structured relations among data that should be established in the course of recognition. Therefore, effective cognition is a part of design competence; (ii) categori-cal schema is found most effective in recognition test. The quality of this type has to do with the quality of its contents. Referential schema can effectively relate elements to one another and to the context in which they are located. This schema contributes to the quality of spatial compositions. Hierarchical schemata are more general that can help identify dependent relations among elements, and therefore reduce the complexity. Conceivably this can increase the efficiency of problem-solving in design.

title	Free-Form Shape Design Using Triangulated Surfaces
source	Computer Graphics, no. 28, pp. 247-256
summary	We present an approach to modeling with truly mutable yet completely controllable free-form surfaces of arbitrary topology. Surfaces may be pinned down at points and along curves, cut up and smoothly welded back together, and faired and reshaped in the large. This style of control is formulated as a constrained shape optimization, with minimization of squared principal curvatures yielding graceful shapes that are free of the parameterization worries accompanying many patch-based approaches. Triangulated point sets are used to approximate these smooth variational surfaces, bridging the gap between patch-based and particle-based representations. Automatic refinement, mesh smoothing, and re-triangulation maintain a good computational mesh as the surface shape evolves, and give sample points and surface features much of the freedom to slide around in the surface that oriented particles enjoy. The resulting surface triangulations are constructed and maintained in real time.

summary	The need for regional styles to exist in architecture has been broadly and long discussed. In general, regionalisms are socially accepted and they should be employed. Discussions usually become more intensified together with the search for inspiration to create new styles in architecture. In Poland Stanislaw Witkiewicz, arts critic and theoretitian, a painter and a writer, created and developed “the Zakopane style” on the turn of the 19th century. This is the only one architectural style focussed on the regional features that has been preserved until nowadays. It referred both to architecture and industrial forms. It was received by the contemporaries with ambivalent attitude, from the uncritical enthusiasm to emotional negation. One side claimed that the style affected the national consciousness and united the nation without the State. According to the other side, “the Zakopane style”, when outside the Podhale region, shocked with its non-conformity to the surroundings. About 1910 there was an attempt to create the style not exactly regional but rather national. The designs referred to neoclassic Old Polish mansion house with a porch supported by columns and high mansard roof. Between 1915 and 1918 projects to rebuild the Polish villages and little towns were thrown open to competition. Afterwards, neatly published project catalogues presented universal, all-Polish type of architecture. In 1918, after I World War and after Poland regained independence, whole housing estates were built in manorial style. At the same time the described sets of competition projects were used together with the new ones, prepared by eg. Polish Hygenic Society (1936). All the project proposals show the all-Polish type of regionalism. Another intensification of discussion concerning the regional style is linked with the post-modernist ideas. Modernism-lacking ornament, cosmopolitan, without any homely features (by the way, he is jolly smart who knows what this “homeliness” is all about) despite its undeniable achievements has been finally faced with crushing criticism. Together with this reaction the search for inspiration in regional features of architecture has been revived. But then there has been a lack of Witkiewicz’s enthusiasm and stubbornness. We deal with constant attempts to solve the problem of creation in regional style. The situation described allows for the statement that there are two forms of regionalism: one on a narrow, territorial and second on the all-Polish scale. No doubt, “the Zakopane style” was the territorial regionalism, and the manorial architecture-the all-Polish one. The condition and quantity of traditional forms are really varied in Poland. For these still existing objects to serve as “model” and inspiration, they have to be examined, classified and made accessible to the designers. The next step is to extract the most distinct features of sub-regions and to popularize the knowledge of these problems. At the Faculty of Architecture of Bialystok Technical University the relative data base concerning the regional architecture is being created on the basis of Microsoft’s ACCESS. It is still another attempt to preserve and uphold the cultural landscape of Poland.

title	Using Post-Occupancy Evaluation To AID Reflection in ConceptualDesign: Creating a Case-Based Design Aid For Architecture
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	The design of large complex "real-world" objects such as buildings requires that the intentions of many potentially competing stakeholders be understood and reconciled. The process of conceptual design itself can be understood as a set of discourses among design team participants and between the designer and the design that gradually reveal these intentions and their relationships to design moves. Our goal is to aid this discourse by creating a Case-based Design Aid (CBDA) that provides design team participants access to specific evaluated cases of experience with previous buildings. This represents a merger of two sets of theories and methodologies: case-based reasoning (CBR) in artificial intelligence; and, post-occupancy evaluation (POE) in architectural research. In developing our CBDA, we have focused on several problems in architectural design: understanding the interactions between intentions, and making links between various modes of understanding and communication, and particularly between verbal description and visual representation. This has led to a particular way of parsing experience, and to several modes of entering and browsing the system. For instance, each case is accessible as a specific building, such as the Santa Clara County Hall of Justice, that can be explored much as an architect might browse a magazine article about the building, looking at a brief text description of the building, photos, and plans. However, each plan is annotated with "problematic situations" that are actually hypertext links into the discursive part of the program. By clicking on the button, the users reaches a "story" screen that lists the intentions of various stakeholders relevant to the problematic situation, a fuller text description of the general problematic situation with a diagram, text and diagram for a specific problematic situation as it operates in a specific building, several general design responses showing how one might respond to the problematic situations, and specific design responses from specific buildings. In addition, the user can browse the system by listing his or her interests and moving directly to stories about a given space type such as "courtroom" or issue such as "way finding." In addition, the designer can access brief synopses of key issues in a building type, for a space type, or for an issue. We are currently implementing the system on the Macintosh using Common Lisp and are focusing on libraries and courthouses as initial building types. Initial feedback from designers has been encouraging. We believe that this approach provides a useful alternative to design guidelines, that often tend to be too prescriptive, and the entirely inductive approach of many designers that may miss critical intentions.

title	Design of a View-Based DSS For Location Planning
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	This paper describes the design of a DSS for locating facility networks. The proposed DSS is based on the principle of dynamic data definitions. The declarative and procedural forms of knowledge involved are identified by a logical analysis of planning tasks. The DSS supports an iterating process of adjusting and evaluating plan options. A flexible and interactive problem solving environment is achieved by means of a user defined set of views that captures both forms of knowledge. Each view describes the system to be planned in terms of a set of variables and attached evaluation procedures. The views are dynamic and linked data structures, so that changes in one view automatically lead to updating all linked views. The DSS supports both the specification of the set of views and its application to solve a specific location problem.
