summary	Progress is being made towards integrating computing into architectural design. This progress is not being made in a coordinated and systematic manner, which is actually a positive factor. Architects will never be scientists or engineers, who hold the distinguishing characteristic of being masters of the scientific method. We have never been so incumbered, although we certainly have given it our best effort. Architects are creative problem solvers, primarily driven by intuition, while coming from a sense of the past and the logic of the present. Our initial attempts at integrating computing into the studio, as evidenced by this collection of papers, is very diverse, based on differing pedagogical assumptions, and the achieving of significantly different results. This would appear to be evidence of a revolutionary approach to the problem rather than a scientific evolutionary approach. Terrific! This is when we as architects are at our best. Although we reach a great number of emphatically dead ends, the successes and discoveries achieved along the way are significant. The diversity and quality of papers submitted suggest that we are indeed pursuing the task of integration in our typical, individual, intuitive, logical manner. I commend all of the authors who submitted proposals and thank them for expanding the envelope of integration into their personal exploration.

title	Relational Database Design Using An Object- Oriented Methodology
source	communications of the ACM. April, 1988. vol. 31: pp. 414-427 : ill. includes a short bibliography
summary	Object-oriented concepts provide a useful abstraction for relational database design. In this article the authors present a design technique that has been used for several projects at General Electric. The methodology is intuitive, expressive, and extensible. The new approach to relational database design is based on the work of Loomis, Sha, and Rumbaugh

summary	This paper will present examples of current practice in the Design Studio course of the BDE, University of Strathclyde. The paper will demonstrate an integrated approach to teaching design, which includes CAD among other visual communication techniques as a means to exploring design concepts and the presentation of complex information as part of the design process. It will indicate how the theoretical dimension is used to direct the student in their areas of independent study. Projects illustrated will include design precedents that have involved students in the review and assessment of landmarks in the history of design. There will be evidence of how students integrate DTP in the presentation of site analysis, research of appropriate design precedents and presentation of their design solutions. CADET underlines the importance of considering design solutions within the context of both our European cultural context and of assessing the environmental impact of design options, for which CAD is eminently suited. As much as a critical method is essential to the development of the design process, a historical perspective and an appreciation of the sophistication of communicative media will inform the analysis of structural form and meaning in a modem urban context. Conscious of the dynamic of social and historical influences in design practice, the student is enabled "to take a critical stand against the dogmatism of the school "(Gadamer, 1988) that inevitably insinuates itself in learning institutions and professional practice.

title	A Generative Expert System for the Design of Building Layouts -- Version 2
source	Artificial Intelligence in Engineering: Design. editor. John J. Gero. Elsevier (Computational Mechanics Publications), 1988. PP. 445-464 : ill. includes bibliography
summary	The paper describes an attempt to increase the intelligence of a CAD system by adding capabilities (1) to systematically enumerate alternative solutions to a design problem, and (2) to take, at the same time, a broad spectrum of criteria or concerns into account. These capabilities are intended to complement the designer's abilities and performance. In connection with such attempts, fundamental problems arise when the objects to be designed have shape and are located in space. These problems are identified, and an approach to solve them is outlined. This approach is currently being tested over a range of domains all of which deal with the design of layouts of rectangles subject to constraints and criteria. The search for alternatives takes place in a state space with properties that make it possible to systematically explore and evaluate the power of various search strategies or planning paradigms. The state space is established through a domain-independent generator, while the evaluation of points in that space is carried out by a domain-dependent tester built up through a process of knowledge acquisition familiar from work with expert systems

source	CAAD futures ‘87 [Conference Proceedings / ISBN 0-444-42916-6] Eindhoven (The Netherlands), 20-22 May 1987, pp. 199-208
summary	Plastic Modelling is a technique which allows the computer model to be easily developed and manipulated. In particular it models not only building geometry but also logical relationships between elements, components, structure and spaces. It is the author's contention that this approach to solid modelling is particularly suitable for the interactive development of architectural design ideas.

title	Concept Design Games
source	Design Studies, Volume 9, Number 3, 1988, pp. 12-23
summary	This paper describes our work on using games as a tool for research in design theory and methods. Games offer a means of isolating certain aspects, or concepts, of designing for purposes of scrutiny. A game provides an environment for a group of players, acting with individual goals and a shared program, to make and transform complex configurations, free of functional requirements. Adjusting game parameters emphasizes different concepts. We have developed nine games that explore a variety of concepts of general interest to those concerned with organizing physical configurations. Beyond these particular concepts, we argue that games are a useful way to couch studies in design theory and methods.

title	Generalizing Active Zones for Set-Theoretic Solid Models
source	8 p. : ill Winchester, UK: IBM UK Scientific Centre, January, 1988. IBM UKSC Report 182. includes bibliography.
summary	A major drawback of the set-theoretic solid model is the global and non-unique way in which it is defined. In a recent paper, Rossignac and Voelcker introduced the concept of the active zone of a primitive or sub-model, which provides a localization of a set-theoretic model which is useful for a number of purposes. A more general, but simplified, definition of the active zone is presented which exploits the properties of the symmetric difference operator. A novel application of the active zone to the interactive graphical editing of set- theoretic solid models is also outlined

title	An Evaluation of Programming Languages and Language Features for Engineering Software Development
source	International Journal of Engineering with Computers. Springer-Verlag, 1988. vol. 3: pp. 183-199
summary	Also published as 'Procedural Programming Languages for the Development of CAD and CAE Systems Software,' in the proceedings of ASME International Conference on Computers in Engineering (1987 : New York, NY). The scope of engineering software has increased dramatically in the past decade. In its early years, most engineering applications were concerned solely with solving difficult numerical problems, and little attention was paid to man- machine interaction, to data management, or to integrated software systems. Now computers solve a much wider variety of problems, including those in which numerical computations are less predominant. In addition, completely new areas of engineering applications such as artificial intelligence have recently emerged. It is well recognized that the particular programming language used to develop an engineering application can dramatically affect the development cost, operating cost. reliability, and usability of the resulting software. With the increase in the variety, functionality, and complexity of engineering software, with its more widespread use, and with its increasing importance, more attention must be paid to programming language suitability so that rational decisions regarding language selection may be made. It is important that professional engineers be aware of the issues addressed in this paper, for it is they who must design, acquire, and use applications software, as well as occasionally develop or manage its development. This paper addresses the need for engineers to possess a working knowledge of the fundamentals of computer programming languages. In pursuit of this, the paper briefly reviews the history of four well known programming languages. It then attempts to identify and to look critically at the attributes of programming languages that significantly affect the production of engineering software. The four procedural programming languages chosen for review are those intended for scientific and general purpose programming, FORTRAN 77, C, Pascal, and Modula-2. These languages are compared and some general observations are made. As it is felt important that professional engineers should be able to make informed decisions about programming language selection, the emphasis throughout this paper is on a methodology of evaluation of programming languages. Choosing an appropriate language can be a complex task and many factors must be considered. Consequently, fundamentals are stressed

title	Automatic Floorplan Design Using PIAF
source	August, 1988. 36 p. : ill. tables
summary	This paper presents PIAF (a Package for Intelligent and Algorithmic Floorplanning), developed at Sydney University Electrical Engineering (SUEE) for use in custom integrated circuit design. Floorplanning plays a crucial role in the design of custom integrated circuits. When design is approached in a top-down fashion, the function to be implemented on silicon is first decomposed in a conceptual phase into a Functional Block Diagram (FBD). This FBD has a 'blocks and buses' structure where blocks represent sub- functions and buses represent the interconnections that carry data and other information between blocks. The decomposition of the function into sub-functions is hierarchical and aims at reducing the complexity of the design problem. When the FBD is known, the floorplanning process may be performed. When this task is performed manually, the designer searches for a relative placement of the blocks and for an area and shape for each block to minimize the overall chip layout area while at the same time meeting design constraints such as design tool limitations, interconnection characteristics and technological design rules. PIAF is a knowledge-based system (KBS) that has been developed at SUEE during the last four years. It relies on a strategy that partitions the floorplanning task in a way that allows efficient use of heuristics and specialized design knowledge in the generation and pruning of the solution space. This paper presents the operation of PIAF and discusses several implementation issues including; KBS structure, knowledge representation, knowledge acquisition, current context memory design, design quality factors and explanation facility. This paper uses a running example to present the operation of each PIAF's KBS-based solving phases

summary	There is a significant variance in the way computer courses are taught at various institutions around the country. Generally, it is useful to think of these courses falling either into a "tool-building" or a "tool-using" category. However, within either category, there is a variety of focus on the application of the "tool". Two courses have been developed at the University of Hawaii at Manoa which deal with computer applications. The first course is more quantitatively oriented, encouraging students to explore ways of dealing with problems in a more complex and substantial manner. This paper deals with the second course whose focus has shifted toward design issues, using the computer as a tool to explore these issues. This course exposes the student, not to training on a specific computer-aided drafting system, but to issues in computer-aided design which include hardware and software systems, human-machine interface, and the nature of the design process. This course seems to be an appropriate model for introducing computer-aided design to undergraduates in a professional design program.

title	A Computational Tool for Evaluation of Seismic Performance of RC Buildings
source	February, 1990. [1] 15 p. : ill. graphs, tables. includes bibliography: p. 10-11
summary	Recent events have demonstrated the damaging power of earthquakes on structural assemblages resulting in immense loss of life and property (Mexico City, 1985; Armenia, 1988; San Francisco, 1989). While the present state-of-the-art in inelastic seismic response analysis of structures is capable of estimating response quantities in terms of deformations, stresses, etc., it has not established a physical qualification of these end-results into measures of damage sustained by the structure wherein system vulnerability is ascertained in terms of serviceability, repairability, and/or collapse. An enhanced computational tool is presented in this paper for evaluation of reinforced concrete structures (such as buildings and bridges) subjected to seismic loading. The program performs a series of tasks to enable a complete evaluation of the structural system: (a) elastic collapse- mode analysis to determine the base shear capacity of the system; (b) step-by-step time history analysis using a macromodel approach in which the inelastic behavior of RC structural components is incorporated; (c) reduction of the response quantities to damage indices so that a physical interpretation of the response is possible. The program is built around two graphical interfaces: one for preprocessing of structural and loading data; and the other for visualization of structural damage following the seismic analysis. This program can serve as an invaluable tool in estimating the seismic performance of existing RC buildings and for designing new structures within acceptable levels of damage

source	CAAD futures ‘87 [Conference Proceedings / ISBN 0-444-42916-6] Eindhoven (The Netherlands), 20-22 May 1987, pp. 71-80
summary	Drawing in all its various forms, from freehand sketching to detailed technical layout, is a type of modelling that designers find indispensable. In many cases, indeed, drawing is the only form of external modelling a designer uses. It has two basic functions: to assist in the externalisation and development of mental concepts and to help in the presentation of these concepts to others. The current thrust of work in computer graphics - although valuable - tends to concentrate almost exclusively on the presentation aspects and it is now possible to create images almost resembling photographs of real objects as well as production drawings of great accuracy and consistency. This paper summarises some of this presentation work as well as developments which might go further in assisting the activities and processes of design.

summary	--- Also published in Artificial Intelligence Developments and Applications edited by J. S. Gero and R. Stanton, North-Holland Pub. 1988. The combination of a heuristic driven search and a tree systems inference technique to induce context-free design grammars is presented. This is achieved by searching for the most useful interpretations of each design in a sample set and discovering regularities in their tree systems representation. The knowledge induced is represented as an accepting tree systems automation and generative grammar. Examples from the domain of architectural design are given

title	The Topdown System and its use in Teaching - An Exploration of Structured, Knowledge-Based Design
doi	https://doi.org/10.52842/conf.acadia.1988.251
source	Computing in Design Education [ACADIA Conference Proceedings] Ann Arbor (Michigan / USA) 28-30 October 1988, pp. 251-262
summary	The Topdown System is a shell for use in developing simple (but we believe non-trivial) knowledge-based CAD systems. It provides a data structure, graphics capabilities, a sophisticated user interface, and programming tools for rapid construction of knowledge bases. Implementation is for Macintosh, Macintosh II, IBM PC/AT, PS12, and Sun workstations. The basic idea is that of top-down design - beginning with a very abstract representation, and elaborating that, in step-by-step fashion, into a complete and detailed representation. The basic operations are real-time parametric variation of designs (using the mouse and slide bar) and substitution of objects. Essentially, then, a knowledge-base in Topdown implements a kind of parametric shape grammar. The main applications of Topdown are in introductory teaching of CAD, and (since it provides a very quick and easy way for a user to develop detailed geometric models) to provide a uniform front-end for a variety of different applications. The shell, and some example knowledge-bases, are publicly available. This paper discusses the principles of the Topdown Shell, the implementation of knowledge bases within it, and a variety of practical design applications.
