title	Design Tools: Future Design Environments for Visualizing Building Performance

summary	In the future of Computer Aided Architectural Design (CAAD), architects clearly need more than just computer aided design and drafting systems (CAD). Unquestionably CAD systems continue to become increasingly powerful, but there is more to designing a good building than its three-dimensional existence, especially in the eyes of all the non-architects of the world: users, owners, contractors, regulators, environmentalists. The ultimate measure of a building's quality has something to do with how well it behaves over time. Predictions about its performance have many different dimensions; how much it costs to build, to operate, and to demolish; how comfortable it is; how effectively people can perform their functions in it; how much energy it uses or wastes. Every year dozens of building performance simulation programs are being written that can predict performance over time along any of these dimensions. That is why the need for both CAD systems and performance predictors can be taken for granted, and why instead it may be more interesting to speculate about the need for 'design tools'. A design tool can be defined as a piece of software that is easy and natural for architects to use, that easily accommodates three-dimensional representations of the building, and that-predicts something useful about a building's performance. There are at least five different components of design tools that will be needed for the design environment of the future.

title	A Common Data Model for Computer Integrated Building
source	computer Integrated Future, CIB W78 Seminar. September, 1991. Unnumbered : some ill. includes bibliography
summary	The connection of various building performance evaluation tools in a collaborative way is an essential request to develop true CAD systems. It is a basic requirement for the future of integrated information systems for building projects, where data concerning multiple aspects of the project can be exchanged during the different design steps. This paper deals with the on-going research concerning the generation of a common data model in the framework of a European collaborative action, the COMBINE Project, which is supported by the CEC, General Directorate XII for Research Science and Development, within the JOULE programme. The first step of the research concerns the progressive construction of a conceptual model and the paper focuses on the development of this Integrated Data Model (IDM). The paper reports on the definition of the architecture of the IDM. The main issues and the methodology of the IDM development are presented. The IDM development methodology is based on successive steps dealing with the identification of the data and context which are considered by the Design Tool Prototypes (DTP) to be connected through the IDM, the conceptual integration of this knowledge, and the implementation of the model on an appropriate software environment

title	On the Thermal Interaction of Building Structure and Heating and Ventilating System
source	Eindhoven University of Technology
summary	In this dissertation, developments in the field of building performance evaluation tools are described. The subject of these tools is the thermal interaction of building structure and heating and ventilating system. The employed technique is computer simulation of the integrated, dynamic system comprising the occupants, the building and its heating and ventilating system. With respect to buildings and the heating and ventilating systems which service them, the practical objective is ensuring thermal comfort while using an optimum amount of fuel. While defining the optimum had to be left for other workers, the issue of thermal comfort is addressed here. The conventional theory of thermal comfort in conditions characteristic for dwellings and offices assumes steady-state conditions. Yet thermal conditions in buildings are seldom steady, due to the thermal interaction between building structure, climate, occupancy, and auxiliary systems. A literature rewiew is presented regarding work on thermal comfort specifically undertaken to examine what fluctuations in indoor climate may be acceptable. From the results, assessment criteria are defined. Although its potentials reach beyond the area of Computer Aided Building Design, a description is given of building and plant energy simulation within the context of the CABD field of technology. Following an account of the present state-of-the-art, the choice for starting from an existing energy simulation environment (ESPR) is justified. The main development areas of this software platform - within the present context - are identified as: fluid flow simulation, plant simulation, and their integration with the building side of the overall problem domain. In the field of fluid flow simulation, a fluid flow network simulation module is described. The module is based on the mass balance approach, and may be operated either in standalone mode or from within the integrated building and plant energy simulation system. The program is capable of predicting pressures and mass flows in a user-defined building / plant network comprising nodes (ie building zones, plant components, etc) and connections (ie air leakages, fans, pipes, ducts, etc), when subjected to flow control (eg thermostatic valves) and / or to transient boundary conditions (eg due to wind). The modelling and simulation techniques employed to predict the dynamic behaviour of the heating and ventilating system, are elaborated. The simultaneous approach of the plant and its associated control is described. The present work involved extensions to the ESPR energy simulation environment with respect to robustness of the program, and with respect to additional plant simulation features, supported plant component models and control features. The coupling of fluid flow, plant side energy and mass, and building side energy simulation into one integrated program is described. It is this "modular-simultaneous" technique for the simulation of combined heat and fluid flow in a building / plant context, which enables an integral approach of the thermal interaction of building structure and heating and ventilating system. A multi stage verification and validation methodology is described, and its applicability to the present work is demonstrated by a number of examples addressing each successive step of the methodology. A number of imaginary and real world case studies are described to demonstrate application of the present work both in a modelling orientated context and in a building engineering context. Then the general conclusions of the present work are summarized. Next and finally, there are recommendations towards possible future work in the areas of: theory, user interface, software structure, application, and technology transfer.

title	ICAtect: Integrating Design Tools for Preliminary Architectural Design
source	Wellington, New Zealand: Computer Science Department, Victoria University
summary	ICAtect is a knowledge based system that provides an interface between expert systems, simulation packages and CAD systems used for preliminary architectural design. This thesis describes its structure and development.The principal work discussed in this thesis involves the formulation of a method for representing a building. This is developed through an examination of a number of design tools used in architectural design, and the ways in which each of these describe a building.Methods of enabling data to be transferred between design tools are explored. A Common Building Model (CBM), forming the core of the ICAtect system, is developed to represent the design tools knowledge of a building. This model covers the range of knowledge required by a large set of disparate design tools used by architects at the initial design stage.Standard methods of integrating information from the tools were examined, but required augmentation to encompass the unusual constraints found in some of the design tools. The integration of the design tools and the CBM is discussed in detail, with example methods developed for each type of design tool. These example methods provide a successful way of moving information between the different representations. Some problems with mapping data between very different representations were encountered in this process, and the solutions or ideas for remedies are detailed. A model for control and use of ICAtect is developed in the thesis, and the extensions to enable a graphical user interface are discussed.The methods developed in this thesis demonstrate the feasibility of an integrated system of this nature, while the discussion of future work indicates the scope and potential power of ICAtect.

title	Integration of Simulation into the Building Design Process
source	J.A. Clarke, J.W. Mitchell, and R.C. Van de Perre (eds.), Proceedings, Building Simulation '91 IBPSA Conference, pp. 367-374
summary	We describe the need for a joint effort between design researchers and simulation tool developers in formulating procedures and standards for integrating simulation into the building design process. We review and discuss current efforts in the US and Europe in the development of next-generation simulation tools and design integration techniques. In particular, we describe initiatives in object-oriented simulation environments (including the US Energy 'Kernel System, the Swedish Ida system, the UK Energy Kernel System, and the French ZOOM program.) and consider the relationship of these environments to recent R&D initiatives in design integration (the COMBINE project in Europe and the AEDOT project in the US).

title	Analogical and inductive reasoning in architectural design computation
source	Swiss Federal Institute of Technology, ETH Zurich
summary	Computer-aided architectural design technology is now a crucial tool of modern architecture, from the viewpoint of higher productivity and better products. As technologies advance, the amount of information and knowledge that designers can apply to a project is constantly increasing. This requires development of more advanced knowledge acquisition technology to achieve higher functionality, flexibility, and efficient performance of the knowledge-based design systems in architecture. Human designers do not solve design problems from scratch, they utilize previous problem solving episodes for similar design problems as a basis for developmental decision making. This observation leads to the starting point of this research: First, we can utilize past experience to solve a new problem by detecting the similarities between the past problem and the new problem. Second, we can identify constraints and general rules implied by those similarities and the similar parts of similar situations. That is, by applying analogical and inductive reasoning we can advance the problem solving process.The main objective of this research is to establish the theory that (1) design process can be viewed as a learning process, (2) design innovation involves analogical and inductive reasoning, and (3) learning from a designer's previous design cases is necessary for the development of the next generation in a knowledge-based design system. This thesis draws upon results from several disciplines, including knowledge representation and machine learning in artificial intelligence, and knowledge acquisition in knowledge engineering, to investigate a potential design environment for future developments in computer-aided architectural design. This thesis contains three parts which correspond to the different steps of this research. Part I, discusses three different ways - problem solving, learning and creativity - of generating new thoughts based on old ones. In Part II, the problem statement of the thesis is made and a conceptual model of analogical and inductive reasoning in design is proposed. In Part III, three different methods of building design systems for solving an architectural design problem are compared rule-based, example-based, and case-based. Finally, conclusions are made based on the current implementation of the work, and possible future extensions of this research are described. It reveals new approaches for knowledge acquisition, machine learning, and knowledge-based design systems in architecture.

title	A digital Procedure of Building Construction: A practical project
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	In 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.

title	The Limitations of Current Working Practices on the Development of Computer Integrating Modelling in Construction
source	computer Integrated Future, CIB W78 Seminar. Calibre, The Netherlands: Eindhoven University of Technology, september, 1991. Unnumbered. includes bibliography
summary	For the construction Industry to improve its processes through the application computer-based systems, traditional working practices must first change to support the integrated control of design and construction. Current manual methods of practice accept the limitations of man to process a wide range of building performance and production information simultaneously. However when these limitations are removed, through the applications of computer systems, the constraints of manual methods need no longer apply. The first generation of computer applications to the Construction Industry merely modelled the divided and sequential processes of manual methods i.e. drafting, specification writing, engineering and quantity calculations, estimating, billing, material ordering data-bases and activity planning. Use of these systems raises expectations that connections within the computer between the processes modelled can actually be made and faster and more integrated information processing be achieved. 'Linking' software is then developed. The end result of this approach was that users were able to produce information faster, present it in an impressive manner but, in reality, no perceived improvement in actual building performance, production economy or efficiency was realized. A current government sponsored Teaching Company Programme with a UK design and build company is addressing the problem of how real economic benefit can be realized through improvement in, amongst other things, their existing computer applications. This work is being carried out by both considering an academic conceptual model of how 'designing for production' can be achieved in computer applications and what is immediately realizable in practice by modelling the integration of a limited number of knowledge domains to which computers are already being applied. i.e. billing from design, estimating and buying. This paper describes each area of work and how they are impacting on each other

summary	During the past ten years computers in architecture have evolved from machines used for analytic and numeric calculation, to machines used for generating dynamic images, permitting the creation of photorealistic renderings, and now, in a preliminary way, permitting the simulation of virtual environments. Digital systems have evolved from increasing the speed of human operations, to providing entirely new means for creating, viewing and analyzing data. The following essays illustrate the growing spectrum of computer applications in architecture. They discuss developments in the simulation of future environments on the luminous screen and in virtual space. They investigate new methods and theories for the generation of architectural color, texture, and form. Authors address the complex technical issues of "intelligent" models and their associated analytic contents. There are attempts to categorize and make accessible architects' perceptions of various models of "reality". Much of what is presented foreshadows changes that are taking place in the areas of design theory, building sciences, architectural graphics, and computer research. The work presented is both developmental, evolving from the work done before or in other fields, and unique, exploring new themes and concepts. The application of computer technology to the practice of architecture has had a cross disciplinary effect, as computer algorithms used to generate the "unreal" environments and actors of the motion picture industry are applied to the prediction of buildings and urban landscapes not yet in existence. Buildings and places from history are archeologically "re-constructed" providing digital simulations that enable designers to study that which has previously (or never) existed. Applications of concepts from scientific visualization suggest new methods for understanding the highly interrelated aspects of the architectural sciences: structural systems, environmental control systems, building economics, etc. Simulation systems from the aerospace industry and computer media fields propose new non-physical three-dimensional worlds. Video compositing technology from the television industry and the practice of medicine are now applied to the compositing of existing environments with proposed buildings. Whether based in architectural research or practice, many authors continue to question the development of contemporary computer systems. They seek new interfaces between human and machine, new methods for simulating architectural information digitally, and new ways of conceptualizing the process of architectural design. While the practice of architecture has, of necessity, been primarily concerned with increasing productivity - and automation for improved efficiency, it is clear that university based studies and research continue to go beyond the electronic replication of manual tasks and study issues that can change the processes of architectural design - and ultimately perhaps, the products.

source	Proceedings of the 3rd European Full-Scale Modelling Conference / ISBN 91-7740044-5 / Lund (Sweden) 13-16 September 1990, pp. 53-64
summary	This paper briefly examines five interrelated themes concerning the use of full-scale simulation models in architectural projects, in the context of research and professional practice. First, the meaning of design is discussed. Second, a multi-functional interpretation of building performance is presented. Third, the main reasons for simulating design projects, in general, and for using full-scale models, in particular, are summarized. Then the antecedent or prerequisite conditions for public participation to occur effectively are discussed. Finally, an overview of the use of full-scale simulation models in European workshops enables us to table four ma n classes of functions for full-scale models.

title	The Effect of Stereovision on the Experience of VR Models of the External Surroundings and the Interior of a Building

summary	Virtual reality offers considerable promise with regard to facilitating the building process. A good example is the facilitation of communication between architects and building companies, sellers and buyers or between community planners and the general public. It is often thought that in order to utilise the potential of VR in, for example, the above-mentioned contexts, it is necessary to use fully fledged versions of VR, including stereovision and the possibility of controlling the VR show. However, if a model can also be presented on less advanced equipment and still interpreted in a way that is useful to the viewer it will be possible to distribute the model simply and effectively. This would make it easier to create a more democratic urban planning process compared with if specialised equipment needed to be used and special shows needed to be arranged. In this study we compared the experience of two VR models (a large indoor exhibition hall and an outdoor street in Gothenburg, Sweden) when presented with and without stereovision. When the experience was measured using the Semantic Environmental Scale (the SMB scale, developed by Küller, 1975, 1991), questions on the experience of presence and six other questions on the experience of the models, the results only revealed one indication that stereovision made a difference. This indication was the result for the SMB factor Enclosedness. Suggestions are presented for future research in this area.

summary	A prototype for computer integrated design/analysis environment is being developed. Due to the nature and size of the author's institution, he opted for compatibility with existing and third party products as well for future developments. Frames are used in Minsky's sense to insulate knowledge and semantics of the tools being integrated. Frames are used again in a more traditional sense insulating components physically. Standards like STEP or AIS were not applied explicitly, but principles behind those standards are reflected in the solution. In the paper an architecture of shallow integration of the tools for integrated structural design is explained in greater detail. Some of the solutions are suggested from the blending of the Object Oriented approach and AI techniques

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

title	Computers for Architects - Only a Tool?
source	Experiences with CAAD in Education and Practice [eCAADe Conference Proceedings] Munich (Germany) 17-19 October 1991
doi	https://doi.org/10.52842/conf.ecaade.1991.x.i9j
summary	The paper states that, as a result of the schism between architecture as art and engineering as rationalism, the architectural community underestimates the computer as tool with a potential to substantially enlarge the possibilities of building design. It is claimed that the computer could serve as coordination tool for the ruptured design process, as a virtual workbench where all design disciplines sit together and develop their designs in enhanced conscience of what the whole design demands. The paper then concludes, that to develop such software tools, architects must participate in the development of software and may no longer be restricted to the role of applicants, especially during their universitary instruction. The corresponding research and training facilities at the University of Karlsruhe, Faculty of Architecture are described.

summary	"Design tools affect the results of the design process" - this is the starting point of our considerations about the efficient use of CAAD within architecture. To give you a short overview about what we want to say with this thesis lets have a short - an surely incomplete - trip through the fourth dimension back into the early time of civil engineering. As CAD in our faculty is integrated in the "Lehrstuhl für Hochbaustatik und Tragwerksplanung" (if we try to say it in English it would approximately be "institute of structural design"), we chose an example we are very familiar with because of its mathematical background - the cone sections: Circle, ellipse, parabola and hyperbola. If we start our trip two thousand years ago we only find the circle - or in very few cases the ellipse - in their use for the ground plan of greek or roman theaters - if you think of Greek amphitheaters or the Colosseum in Rome - or for the design of the cross section of a building - for example the Pantheon, roman aqueducts or bridges. With the rediscovery of the perspective during the Renaissance the handling of the ellipse was brought to perfection. May be the most famous example is the Capitol in Rome designed by Michelangelo Buonarotti with its elliptical ground plan that looks like a circle if the visitor comes up the famous stairway. During the following centuries - caused by the further development of the natural sciences and the use of new construction materials, i.e. cast-iron, steel or concrete - new design ideas could be realized. With the growing influence of mathematics on the design of buildings we got the division into two professions: Civil engineering and architecture. To the regret of the architects the most innovative constructions were designed by civil engineers, e.g. the early iron bridges in Britain or the famous bridges of Robert Maillard. Nowadays we are in the situation that we try to reintegrate the divided professions. We will return to that point later discussing possible solutions of this problem. But let us continue our 'historical survey demonstrating the state of the art we have today. As the logical consequence of the parabolic and hyperbolic arcs the hyperbolic parabolic shells were developed using traditional design techniques like models and orthogonal sections. Now we reach the point where the question comes up whether complex structures can be completely described by using traditional methods. A question that can be answered by "no" if we take the final step to the completely irregular geometry of cable- net-constructions or deconstructivistic designs. What we see - and what seems to support our thesis of the connection between design tools and the results of the design process - is, that on the one hand new tools enabled the designer to realize new ideas and on the other hand new ideas affected the development of new tools to realize them.

title	A First Step Towards an Intelligent Integrated Design System in the Building Field
source	computer Integrated Future, CIB W78 Seminar. September, 1991. Unnumbered pages : ill. includes bibliography
summary	This article presents the work the Knowledge Base Group is achieving towards the integration of Artificial Intelligence based facilities in the Building design process. After an overview of the current state of the integrated design process, the context and the technical guidelines to realize computer integrated software in the building design field is described. Then some tools are presented to model the knowledge (the HBDS method) and to implement such model in our Mips home-made knowledge modeling software platform (including object-oriented database management facilities, expert system reasoning facilities, hypertext edition facilities, 3D-design and 3D-view modules...). Finally the authors describe the Quakes application devoted to assess detached house anti-seismic capabilities during the design process. A deep conceptual model considers all the semantic entities (columns, resistant panels, openings, ...) involved in the anti-seismic expertise. Using both this conceptual model description of a detached house and the 3D design tool, they input the project. Then the seismic expertise is driven in a divide and conquer approach and records the alleged configuration recognized automatically linked to the corresponding section of the building regulation

summary	Design can be considered a process leading to the definition of a physical form that achieves a certain predefined set of objectives. The process comprises three distinct operations: (1) definition of the desired set of performance criteria (design goals); (2) production of alternative design solutions; (3) evaluation of the expected performances of alternative design solutions, and comparing them to predefined criteria. Difficulties arise in performing each one of the three operations, as well as in combining them into a purposeful, unified process. First, it is difficult to define the desired performance criteria prior to and independently of, the search for an acceptable solution that achieves them, since many aspects of the desired criteria can only be discovered through the search for an acceptable solution. Furthermore, the search for such a solution may well alter the definition of these criteria, as new criteria and incompatibilities between existing criteria are discovered. Second the generation of a design solution is a task demanding creativity, judgement, and experience, all three of which are difficult to define, teach, and otherwise capture in some explicit manner. Third, it is difficult to evaluate the expected performances of alternative design solutions and to compare them to the predefined criteria. Design parameters interact with each other in complex ways, which cause effects and side effects. Predicting the expected performances of even primary effects involves extrapolating non-physical characteristics from the proposed solution's physical organization, a process which relies on a host of assumptions (physical, sociological, psychological, etc.) and hence is seldom a reliable measure. A fourth problem arises from the need to coordinate the three operations in an iterative process that will converge on an acceptable design solution in reasonable time. Computational techniques that were developed in the past to assist designers in performing the above mentioned activities have shown limitations and proved inadequate to a large degree. In this paper we discuss the work in progress aimed at developing an intelligent support system for building and architectural design, which will be able to play a decisive role in the definition, evaluation and putting into effect of the design choices.

title	Sketch as Sketch Can - Design Sketching with Imperfect Aids and Sketchpads of the Future
source	Experiences with CAAD in Education and Practice [eCAADe Conference Proceedings] Munich (Germany) 17-19 October 1991

summary	Sketching plays a manifold role in design and design education now as much as it did in the computerless days. Design sketching is indispensable during the early phases of the architectural design process. But if we ask architects and design educators alike what they are doing with computers, idea sketching is the least mentioned answer if not left out entirely. It is not because they are computer-illiterates, as the computer industry would tend to imply, but because their computers are not offering an adequate environment for design sketching. In education this means that those trying to create computeraided design sketching courses are confronted with the choice of either working with imperfect tools, or waiting for better tools. But by exploring the possibilities in available surrogates we will build the necessary experiences for specifying what is really useful for idea-sketching. Without such exercises, we will never go beyond the electronic metaphor of the sketchbook with pencil or marker.

title	Handbook of genetic algorithms
source	Van Nostrand Reinhold, New York
summary	This book sets out to explain what genetic algorithms are and how they can be used to solve real-world problems. The first objective is tackled by the editor, Lawrence Davis. The remainder of the book is turned over to a series of short review articles by a collection of authors, each explaining how genetic algorithms have been applied to problems in their own specific area of interest. The first part of the book introduces the fundamental genetic algorithm (GA), explains how it has traditionally been designed and implemented and shows how the basic technique may be applied to a very simple numerical optimisation problem. The basic technique is then altered and refined in a number of ways, with the effects of each change being measured by comparison against the performance of the original. In this way, the reader is provided with an uncluttered introduction to the technique and learns to appreciate why certain variants of GA have become more popular than others in the scientific community. Davis stresses that the choice of a suitable representation for the problem in hand is a key step in applying the GA, as is the selection of suitable techniques for generating new solutions from old. He is refreshingly open in admitting that much of the business of adapting the GA to specific problems owes more to art than to science. It is nice to see the terminology associated with this subject explained, with the author stressing that much of the field is still an active area of research. Few assumptions are made about the reader's mathematical background. The second part of the book contains thirteen cameo descriptions of how genetic algorithmic techniques have been, or are being, applied to a diverse range of problems. Thus, one group of authors explains how the technique has been used for modelling arms races between neighbouring countries (a non- linear, dynamical system), while another group describes its use in deciding design trade-offs for military aircraft. My own favourite is a rather charming account of how the GA was applied to a series of scheduling problems. Having attempted something of this sort with Simulated Annealing, I found it refreshing to see the authors highlighting some of the problems that they had encountered, rather than sweeping them under the carpet as is so often done in the scientific literature. The editor points out that there are standard GA tools available for either play or serious development work. Two of these (GENESIS and OOGA) are described in a short, third part of the book. As is so often the case nowadays, it is possible to obtain a diskette containing both systems by sending your Visa card details (or $60) to an address in the USA.
