title	Coloured Petri Nets: Basic Concepts
source	2nd ed., Springer Verlag, Berlin
summary	This book presents a coherent description of the theoretical and practical aspects of Coloured Petri Nets (CP-nets or CPN). It shows how CP-nets have been developed - from being a promising theoretical model to being a full-fledged language for the design, specification, simulation, validation and implementation of large software systems (and other systems in which human beings and/or computers communicate by means of some more or less formal rules). The book contains the formal definition of CP-nets and the mathematical theory behind their analysis methods. However, it has been the intention to write the book in such a way that it also becomes attractive to readers who are more interested in applications than the underlying mathematics. This means that a large part of the book is written in a style which is closer to an engineering textbook (or a users' manual) than it is to a typical textbook in theoretical computer science. The book consists of three separate volumes. The first volume defines the net model (i.e., hierarchical CP-nets) and the basic concepts (e.g., the different behavioural properties such as deadlocks, fairness and home markings). It gives a detailed presentation of many small examples and a brief overview of some industrial applications. It introduces the formal analysis methods. Finally, it contains a description of a set of CPN tools which support the practical use of CP-nets. Most of the material in this volume is application oriented. The purpose of the volume is to teach the reader how to construct CPN models and how to analyse these by means of simulation. The second volume contains a detailed presentation of the theory behind the formal analysis methods - in particular occurrence graphs with equivalence classes and place/transition invariants. It also describes how these analysis methods are supported by computer tools. Parts of this volume are rather theoretical while other parts are application oriented. The purpose of the volume is to teach the reader how to use the formal analysis methods. This will not necessarily require a deep understanding of the underlying mathematical theory (although such knowledge will of course be a help). The third volume contains a detailed description of a selection of industrial applications. The purpose is to document the most important ideas and experiences from the projects - in a way which is useful for readers who do not yet have personal experience with the construction and analysis of large CPN diagrams. Another purpose is to demonstrate the feasibility of using CP-nets and the CPN tools for such projects. Together the three volumes present the theory behind CP-nets, the supporting CPN tools and some of the practical experiences with CP-nets and the tools. In our opinion it is extremely important that these three research areas have been developed simultaneously. The three areas influence each other and none of them could be adequately developed without the other two. As an example, we think it would have been totally impossible to develop the hierarchy concepts of CP-nets without simultaneously having a solid background in the theory of CP-nets, a good idea for a tool to support the hierarchy concepts, and a thorough knowledge of the typical application areas.

summary	The existing system of architectural education ( including computer ) as has shown practice has appeared not absolutly perfect. It not capable to dynamic changes, active introduction of a new engineering and computer technologies, to realization about of the inquiries of a modern time. It suggest of a way of search of new models of computer training. The computer education is represented by us as certain a universal system, which permits to solve the problem of arcitectural education at a higher level. The opportunities of computers and computer technologies at such approach are used as means of increase of efficiency teaching and training. The orientation goes on final result: a opportunity to generate of the creative decisions by learnees, based on attraction of received knowledge and use for their realization of arsenal of practical skills and skills. The system represents not only certain set of experiences elements, necessary and final result sufficient for achievement, but also quite certain interrelation between them. It means, that the knowledge from a initial rate " The Introduction in computer training" must be secured and transformed for utilization in special rates and through them- in practice. The functional nucleus of the software package of such universal system is under construction as opened, apparatus an independent system. A central part of a system is a database, the structure of which is uniform for all other modules and side of enclosures. The conceptual model of a system is under construction on principles structure idea, visualization, multimedia. The listed principles are realized in model so that to encourage the user to independent creative work.

title	Discourse Model for collaborative design
source	Computer-Aided Design, Vol. 28 (5) (1996) pp. 333-345
summary	A Discourse Model, including a structure and a process, is developed that provides software support for collaborative engineering design. The model shares characteristics of other design systems in the literature,including frames, constraints, semantic networks, and libraries of sharable design objects. It contributes a new model for conflict-aware agents, dynamic identification and dissemination of agent interest sets, avirtual workspace language, automatic detection of conflict, and a unique protocol for negotiation that ensures that interested agents have an opportunity to participate. The model is implementation independent andapplicable to many research and commercial design environments currently available. An example scenario is provided in the architecture/engineering/construction domain that illustrates collaboration during theconceptual design of a fire station.

title	Spatial objects and intelligent agents in a virtual environment
source	Automation in Construction 5 (3) (1996) pp. 141-150
summary	Many CAD software tools are available today for architectural design. They are useful for drafting, but tools that support design development in an early stage are still missing. In a conceptual phase of the design aspects other than precision and measurements become important. With today's knowledge and technological possibilities new ways of interaction, different data structures and intelligent support tools can be implemented. This article describes our research on new ways to support the design development in an early stage. The concept of modelling spaces, the virtual modelling tool and the integration of intelligent agents are described.

title	Artificial Life
source	Boden, M. A. (1996). The Philosophy of Artificial Life, 39-94.New York and Oxford: Oxford University Press
summary	Artificial Life contains a selection of articles from the first three issues of the journal of the same name, chosen so as to give an overview of the field, its connections with other disciplines, and its philosophical foundations. It is aimed at those with a general background in the sciences: some of the articles assume a mathematical background, or basic biology and computer science. I found it an informative and thought-provoking survey of a field around whose edges I have skirted for years. Many of the articles take biology as their starting point. Charles Taylor and David Jefferson provide a brief overview of the uses of artificial life as a tool in biology. Others look at more specific topics: Kristian Lindgren and Mats G. Nordahl use the iterated Prisoner's Dilemma to model cooperation and community structure in artificial ecosystems; Peter Schuster writes about molecular evolution in simplified test tube systems and its spin-off, evolutionary biotechnology; Przemyslaw Prusinkiewicz presents some examples of visual modelling of morphogenesis, illustrated with colour photographs; and Michael G. Dyer surveys different kinds of cooperative animal behaviour and some of the problems synthesising neural networks which exhibit similar behaviours. Other articles highlight the connections of artificial life with artificial intelligence. A review article by Luc Steels covers the relationship between the two fields, while another by Pattie Maes covers work on adaptive autonomous agents. Thomas S. Ray takes a synthetic approach to artificial life, with the goal of instantiating life rather than simulating it; he manages an awkward compromise between respecting the "physics and chemistry" of the digital medium and transplanting features of biological life. Kunihiko Kaneko looks to the mathematics of chaos theory to help understand the origins of complexity in evolution. In "Beyond Digital Naturalism", Walter Fontana, Guenter Wagner and Leo Buss argue that the test of artificial life is to solve conceptual problems of biology and that "there exists a logical deep structure of which carbon chemistry-based life is a manifestation"; they use lambda calculus to try and build a theory of organisation.

title	Functional Integration in CAD Systems
source	Advances in Engineering Software, 25, 103-109
summary	This paper examines the issue of integration in CAD systems and argues that for integration to be effective, it must address the functional aspects of a CAD system. It discusses the need for integrated systems and, within a structural engineering context, identifies several facets of integration that should be targeted. These include 2-D drafting and 3-D modelling, graphical and non-graphical design information, the CAD data structure and its user interface, as well as integration of the drafting function with other engineering applications. Means of achieving these levels of integration are briefly discussed and a prognosis for the future development of integrated systems explored. Particular attention is paid to the emergence (and potential role) of `product models' which seek to encapsulate the full range of data elements required to define completely an engineering artefact.

title	Data structures and DBMS for computer-aided design systems
source	Advances in Engineering Software, 25(2/3), 123-129
summary	The structures for the storage of data in CAD systems influence to a large extent the effectiveness of the system. This paper reviews the wide range of data structures and database management systems (DBMS) available for structuring CAD data. Examples of basic data types are drawn from the MODULA-2 language. The relationship between these basic data types, their composite structures and the classical data models (on which many DBMS are based) is discussed, and the limitations of existing DBMS in modelling CAD data highlighted. A set of requirements for CAD database management systems is drawn up and the emerging role of product models (which seek to encapsulate the totality of data elements required to define fully an engineering artefact) is explored.

title	GIS and Environmental Modeling: Progress and Research Issues
source	Fort Collins, CO: GIS World Books, pp.451-454
summary	GIS and Environmental Modeling: Progress and Research Issues Michael F. Goodchild, Louis T. Steyaert, Bradley O. Parks, Carol Johnston, David Maidment, Michael Crane, and Sandi Glendinning, Editors With growing pressure on natural resources and landscapes there is an increasing need to predict the consequences of any changes to the environment. Modelling plays an important role in this by helping our understanding of the environment and by forecasting likely impacts. In recent years moves have been made to link models to Geographical Information Systems to provide a means of analysing changes over an area as well as over time. GIS and Environmental Modeling explores the progress made to date in integrating these two software systems. Approaches to the subject are made from theoretical, technical as well as data stand points. The existing capabilities of current systems are described along with important issues of data availability, accuracy and error. Various case studies illustrate this and highlight the common concepts and issues that exist between researchers in different environmental fields. The future needs and prospects for integrating GIS and environmental models are also explored with developments in both data handling and modelling discussed. The book brings together the knowledge and experience of over 100 researchers from academic, commercial and government backgrounds who work in a wide range of disciplines. The themes followed in the text provide a fund of knowledge and guidance for those involved in environmental modelling and GIS. The book is easily accessible for readers with a basic GIS knowledge and the ideas and results of the research are clearly illustrated with both colour and black and white graphics.

title	From symbol to form: a framework for conceptual design
source	Computer-Aided Design, Vol. 28 (11) (1996) pp. 853-870
summary	This paper presents the design of a software framework for conceptual design. It develops an approach to mapping an evolving symbolic description of design into a geometric description. The distinct elements ofthe symbol-form mapping are: (a) deriving spatial relationships between objects as a consequence of the functional relationship; (b) instantiating alternative feasible solutions subject to these relationships; and (c)presenting the evolving descriptions of geometry. Computational support for each of these elements is provided within a conceptual design framework. The paper presents components of the framework, explicitlyidentifies interactions between these components, and explains how these interactions are developed into an integrated framework. It presents the rationale for the design decisions made in the framework. Anexample is presented to clarify the approach adopted. The applicability of the approach is then discussed.

title	From an architectural sketch to its semantic representation
source	The Int. Journal of Construction IT 4(2), pp. 67-84
summary	This paper presents an essay on the needs and viability of the semantic harnessing of architectural sketches in the framework of integrated computer design. A symbolic and relation representation is proposed as the shared architectural model. This is structured with the practical proposals of cognitive sciences about knowledge creation and manipulation. An experiment is described which observes and analyses the composition of professional sketches. Its results are taken as directives to build the architectural model content. Two computer software are presented as prototypes for managing a case base of architectural knowledge and deducing the semantic concepts from sketches. Back to Search Results

title	DEFLECT: A Computer Aided Learning Package For Teaching Structural Design
doi	https://doi.org/10.52842/conf.ecaade.1996.253
source	Education for Practice [14th eCAADe Conference Proceedings / ISBN 0-9523687-2-2] Lund (Sweden) 12-14 September 1996, pp. 253-262
summary	The teaching of structures and its integration with design teaching has been seen as one of the major problems in design education in schools of architecture world-wide. A number of suggestions have been put forward to improve the quality of teaching in structures in architecture. These include the production of computer based learning materials, and the use of the computer as a ‘substitute’ tutor. This paper reports on a SHEFC funded project jointly carried out by the Department of Civil Engineering, University of Paisley, the Mackintosh School of Architecture, and Lamp Software. The project aims to build a computer-assisted learning package on the response of structures to load. The software will be used as an interactive teaching tool for both architectural and engineering students. The package has three levels: Beginners (Level 1), Intermediate (Level 2) and Advanced (Level 3). The first two levels have been completed after continuous feedback from both institutions. Level 1 is geared towards architectural and engineering students to help them understand structural behaviour of building components, such as deflection. Level 2 is a graphical editor that enables students to draw precisely the structure of their designs, investigate the deflection of structural members and identify areas of tension and compression. Level 3 is a design tool aimed at architectural and civil engineering students where they can design and analyse realistic structures by choosing structural members from a library, and specify materials and multiple loads. Prior to its final release, the software package was appraised by students from both institutions. Analysis of results from questionnaires revealed that students expressed a great deal of 'satisfaction' with many of its teaching and learning attributes. The outcome of this project will promote and enhance students’ understanding of the response of structures to load; it will also help students grasp the impact of varying building materials and cross sectional properties on the structural form.

source	Computerised Craftsmanship [eCAADe Conference Proceedings] Paris (France) 24-26 September 1998
summary	The pedagogic approach in the architectural field is suffering a deep change taking in consideration the impact that has been produced mainly by the CAD and multimedia procedures. An additional view to be taken in consideration is the challenge produced by the influence of advanced IT which since 1990-92, has affected positively the exchange of information among people of the academic environment. Several studies confirm this hypothesis, from the wide cultural spectrum when the digitalization process was emerging as an alternative way to data processing (Bateson 1976) to the pedagogical-computational side analyzed by (Papert 1996). One of the main characteristics indicated by S. Papert (op.cit) is the idea of "self teaching" which students are used everywhere due to the constant augment of "friendly" software and the decreasing costs of hardware. Another consequences to point out by S. Paper (op.cit) is that will be more probably that students at home will have more actualized equipment that most of the computer lab. of schools in general. Therefore, the main hypothesis of this paper is, "if we are able to combine usual tutorials design methods with the concept of "self-teaching" regarding the paradigmatic architectural models that are used in practically all the schools of architecture (Le Corbusier, F.L.Wright, M.v. der Rohe, M.Botta, T.Ando, etc.) using a Web site available to everybody, what we are doing is expanding the existing knowledge in the libraries and fulfill the future requirements of the newly generations of students".

title	Form Processing: A System for Architectural Design
source	Harvard University
summary	This thesis introduces a new approach to developing software for formal synthesis in architectural design. It presents theoretical foundations, describes prototype specifications for computable implementation, and illustrates some examples. The approach derives from the observation that architects explore ideas through the use of sequences of drawings. Architects derive each drawing in a sequence from its predecessor by executing some transformation on a portion of the drawing. Thus, a formal design state is established by a sequence of drawings with historical information about their construction through progressive transformations. The proposed system allows an architect to develop a design in three ways. First, a new transformation can be added to a current sequence of drawings. Second, existing sequences can be edited by exchanging their subset sequences. Third, an existing sequence can be revised parametrically by assigning new values to its design variables. The system implements scripts that specify categories of shapes and transformations between any two shape categories. When an instance of a shape category is found in a design, a transformation can replace it with an instance of another shape category. Recursive application of a given set of transformations to an initial shape instance produces a sequence of drawings that represents a formal design state. The system encodes this formal design state as an assembly of all the shape instances used and their relationships (nesting, emergent and replacement). Furthermore, this assembly, called a construction graph, allows the existing sequences to be edited efficiently by exchanging subsets and to be revised parametrically. The advantage of this approach as demonstrated in the examples is that it allows intuitive, rapid and interactive construction of complex designs. Moreover, design knowledge can be captured by scripts that depict heuristic shapes and transformations as well as by assembled construction graphs which depict cases of formal design. Such a reusable and expandable knowledge base is essential for assisting disciplined and creative architectural design.

title	A World-wide Questionnaire Survey on the Use of Computers in Architectural Education
doi	https://doi.org/10.52842/conf.ecaade.1997.x.c8o
source	Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
summary	The paper reports on a study which examines the impact on architectural education needs arising from the changes brought about by the implications of CAD teaching/learning (CAI/CAL). The findings reflect the views of fifty-one (51) architecture schools through a world-wide questionnaire survey conducted in mid 1996. The survey was structured to cover four continents represented by seven countries, namely the USA, UK, Israel, Australia, Canada, Sweden and the Netherlands. Structurally the main findings of this study are summarised under five areas, namely: 1) General Information, 2) Program of Study (curriculum) and CAD course, 3) CAD Laboratories: Hardware, Software, 4) Departmental Current and Future Policies, 5) Multi-media and Virtual Reality. Principally, there were three main objectives for using the computers survey. Firstly, to accommodate a prevalent comprehension of CAD integration into the curriculum of architecture schools world wide. Secondly, to identify the main key factors that control the extent of association between CAD and architectural curriculum. Thirdly, to identify common trends of CAD teaching in Architecture schools world-wide and across the seven countries to establish whether there are any association between them. Several variables and factors that were found to have an impact on AE were examined, namely: the response rate, the conventional methods users and the CAD methods users amongst students, CAD course employment in the curriculum, age of CAD employment, the role of CAD in the curriculum, CAD training time in the Curriculum, CAD laboratories/Hardware & Software, computing staff and technicians, department policies, Multi-Media (MM) and Virtual-Reality (VR). The statistical analysis of the study revealed significant findings, one of which indicates that 35% of the total population of students at the surveyed architecture schools are reported as being CAD users. Out of the 51 architecture schools who participated in this survey, 47 have introduced CAD courses into the curriculum. The impact of CAD on the curriculum was noted to be significant in several areas, namely: architectural design, architectural presentation, structural engineering, facilities management, thesis project and urban design. The top five CAD packages found to be most highly used across universities were, namely, AutoCAD (46), 3DStudio (34), Microstation (23), Form Z (17), ArchiCAD (17). The findings of this study suggest some effective and efficient future directions in adopting some form of effective CAD strategies in the curriculum of architecture. The study also serves as an evaluation tool for computing teaching in the design studio and the curriculum.

title	Multimedia Teachware in the Field of Architectural Design
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary	Software systems for educational purposes have been developed and used in many application areas. In this paper we will describe a development in the field of building science. ClAD is a teachware system directed to be used in the education of students of architecture as well as a tool that gives a survey to architects and engineers in the practice. In the first place it provides information about the use of computer science technologies in the building design process. Furthermore, information about the architectural design process itself is included. Based on an analysis of general requirements and specific demands of the application field we describe our solution concept. Very important conclusions are that the system has to integrate the use of all media which are usually used by architects by offering a flexible and well-designed user interface and allowing a high degree of interactive work. After covering the development process as a combination of top down and bottom up strategies we describe the overall structure of ClAD as a modular system which can be extended and updated easily. Finally, we give an overview about some parts of the system to demonstrate the implementation of the concepts mentioned above.

title	CAAD - To Teach, or not to Teach?
doi	https://doi.org/10.52842/conf.ecaade.1996.403
source	Education for Practice [14th eCAADe Conference Proceedings / ISBN 0-9523687-2-2] Lund (Sweden) 12-14 September 1996, pp. 403-406
summary	Usefulness of CAAD in architectural practice is not a matter to discuss. Probably it is very hard nowadays to find an architect practitioner who really believes, that CAAD isn't a useful tool in architectural office. Finding a job after finishing the studies at faculty of architecture isn't easy without knowledge of computer. For us as teachers it is a great challenge. We want our students to be as well as possible prepared for their work. So problem, how to put CAAD into amount of their knowledge is a very important point. However, computers are nowadays probably the fastest changing element of our reality. Differences between software and hardware used a few years ago and now are sometimes colossal. In spite of the fact, that in the field of using computers in design we are usually ahead of most architects practitioners, I think we are sentenced to be backward contemporary demands. Program of teaching CAAD prepared even with great care and accuracy is obsolete even when it starts. It is impossible to catch up with future. Which is a right place for CAAD in architectural education? Is it not true, that sometimes we try to teach CAAD by architecture instead of teaching architecture by CAAD? For many students CAAD is the most natural tool for design, a tool which has replaced pencil and a sheet of paper. Is it our success? I am not so sure. Limitations of CAAD systems are much bigger than pencil's one. Like every sophisticated tool it limits amount of possible solutions. CAAD should not be a fetish! I think maybe it is not such a stupid idea not to teach CAAD, but let our students find a right place for it like for any other useful tools?

title	Weighing alternatives decision support systems for housing management in the Netherlands
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary	Under nowadays market conditions housing quality will be a major issue for the management of the housing stock. Even under the existing housing shortness in the Netherlands vacancy and demolition of post-war housing blocks is not any more a rare incident. In most cases the reason of depreciation and decay is found in a mismatch between supply and demand, caused by either an inadequate design or shifted market conditions.To cure the problems a range of possible interventions has been developed, varying from neglection and minor changes to radical redesign and demolition. Recently some decision support systems are developed to overview and compare the consequences of different concepts and strategies. Our paper provides an overview of recent Dutch tools and systems for this purpose, partly including computer software. Special attention is paid to the weighing of alternative interventions and practical experiences.

summary	In earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.
