title	Perspective on Artificial Intelligence Programming
source	Science. February, 1986. vol. 231: pp. 951-956
summary	Programming systems for artificial intelligence application use specialized languages, environments, and knowledge-based tools to reduce the complexity of the programming task. Language style based on procedure, objects logic rules, and constraints reflect different models for organizing programs and facilitate program evaluation and understandability. To make programming easier, multiple styles can be integrated as sublanguages in programming environment. Programming environments provide tools that analyze programs and create informative displays of their structure. Programs can be modified by direct interaction with these displays. These tools and languages are helping computer scientists to regain a sense of control over systems that have become increasingly complex

title	Structuring a Learning Building Design System
source	Advancing Building Technology, CIB International Congress (10th : 1986 : Washington D. C.). 9 p. : ill. includes bibliography
summary	It is now vital to aim at formulating computer system modules that possess a high ability to adapt their behavior to fundamental human values and a complex and unstandardized (not uniform) building process but at the same time put constraints on them so that we don't end up with a confusion of computerized routines hard to access, control and understand. In the paper formulations are made of basic artifact skeletons outgoing from the properties to give integrated CAD systems and to those rules by which the growth of the systems are governed. System learning domains including conceptual modelling tools are presented aiming at supporting professional skill, creativity and integration between process actors. The basis for system implementation is frames, descriptive language (PROLOG) and relational databases with regard taken to future possibilities to parallel processing

title	A Conceptual Framework for Communication -Instruction in Architectural Design
source	Pennsylvania State University
summary	Existing design models, it is generally acknowledged, are inadequate to deal with the complexity of contemporary situations; and an assessment of self-conscious design manifests a slow development in the power and scope of conceptualizing. The quality of knowledge and conceptual tools available to the designer largely determine his ability to conceive and accomplish; conversely, the limitations of method are reflected in design solutions. Some emerging social problem-solving paradigms, which seek to construct a cognitive psychology of problem solving, have a direct relevance to architectural design. Notwithstanding the traditional criticism and scepticism, problem solving is predicated by task environment and problem space as these have a significant impact on design synthesis. Despite a rigorous search for theoretical perspectives and methods, the concern for the quality of the physical environment persists unabated. Historically, architecture has depended on other disciplines for its theoretical insight; but the application of borrowed theories without a viable framework for translation has often resulted in misinterpretation. Aggravating the problem is the art-science controversy which has consequences for architectural practice and education. What is required is a unified approach encompassing the scientific and artistic modes of inquiry. But a unified perspective, involving vast and disparate areas of human knowledge, demands a conceptual framework for integrative learning. The proposed model of this study provides such a framework and calls for a re-examination of the conventional boundaries of design disciplines. It advocates an interdisciplinary approach and recognizes the design process as inherently a learning process; this shifts the emphasis from product to process and allows students to plan and assess their own design/learning experience. While the study focuses on substantive issues, it identifies a strategy for integrative learning applicable within the existing context of design education. Despite its untested nature, the proposed model can become a vehicle for stimulating coordination of all facets of human knowledge and experience toward creative design synthesis. It inculcates a sense of critical assessment of generative ideas by presenting a conceptually clearer picture of the design process to elicit a response to and a better understanding of the task environment of architecture.

title	Transformations of Languages of Designs
source	University of California, Graduate School of Architecture and Urban PIanning, Los Angeles
summary	Stylistic change and innovation is a central and traditional issue in art and architecture. In this study, a formal model is developed for representing stylistic change. Styles are defined in terms of rule-based systems called shape grammars that generate languages of designs. Changes in styles are represented as transformations of the shape grammars that define these styles. The model is first sketched informally and considered in relation to other, traditional approaches to style and change. It is then presented in detail and illustrated with numerous simple examples. Last, the model is applied to describe actual, historical examples of stylistic transformations: one in the decorative arts, one in the fine arts, and one in architecture.

title	Learning in the Domain of Decisions and Performances
source	IAAI'86 Conference. 1986. pp. i:1:1-9. CADLINE has abstract only
summary	Many domains present themselves as mappings between two classes of spaces: decision spaces and performance spaces. All design domains can be represented in this manner where the designer takes decisions which manifest themselves as performances in the designed artifact. Learning in these domains can take account of the structural characteristics of the spaces and of the mappings. This paper describes a system, PARE, which learns in the domain of decisions and performances by making use of the characteristics of a particular structuring concept known as 'Pareto optimality.' Much is known about the concept and its features which are used as hypotheses. If the hypotheses succeed then learning takes place by specializing the hypotheses' characteristics. Characterizations of Pareto optimality are described and the feature extraction process shown. The feature extraction process utilizes fuzzy pattern matching. An example of the system, written in ConSUN workstations, is presented from the domain of fenestration design

title	The Computability of Architectural Knowledge
source	The Electronic Design Studio: Architectural Knowledge and Media in the Computer Era [CAAD Futures ‘89 Conference Proceedings / ISBN 0-262-13254-0] Cambridge (Massachusetts / USA), 1989, pp. 171-185
summary	In an important contribution to the theoretical foundation of design computing, Mitchell noted "an increasingly urgent need to establish a demonstrably sound, comprehensive, rigorously formalized theoretical foundation upon which to base practical software development efforts" (Mitchell, 1986). In this paper we propose such a theoretical framework. A basic assumption of this work is that the advancement of design computing is dependent upon the emergence of a rigorous formulation of knowledge in design. We present a model of knowledge in architectural design which suggests a promising conceptual basis for dealing with knowledge in computer-aided design systems. We require models which can represent the formal knowledge and manipulative operations of the designer in all of their complexity-that is formal models rather than just geometric models. Shape Grammars (Stiny,1980) represent an example of such models, and constitute a relatively high level of design knowledge as compared to, for example, use of symmetry operations to generate simple formal configurations. Building upon an understanding of the classes of design knowledge as the conceptual basis for formal modeling systems may contribute a new realization of the potential of the medium for design. This will require a comprehensive approach to the definition of architectural and design knowledge. We consider here the implications of a well-defined body of architectural and design knowledge for design education and the potential mutual interaction-in a knowledge-rich environment-of design learning and CAAD learning. The computational factors connected with the representation of design knowledge and its integration in design systems are among the key problems of CAAD. Mitchell's model of knowledge in design incorporates formal knowledge in a comprehensive, multi-level, hierarchical structure in which types of knowledge are correlated with computational concepts. In the main focus of this paper we present a structured, multi-level model of design knowledge which we discuss with respect to current architectural theoretical considerations. Finally, we analyze the computational and educational relevance of such models.

title	Case Studies in Architectural CADD Education
doi	https://doi.org/10.52842/conf.acadia.1986.157

summary	Stages in the formation of concepts necessary for mastery can be observed in cognitive development in many different areas of study. These stages seem to follow a particular hierarchy common to most learners. Distinct levels can be recognized by patterns of procedural errors. The remediation of errors can then take the form of building a conceptual framework rather than training in procedural patterns. This has been found to be highly efficient for learners at all stages since it can be aimed at the underlying problem area and not at isolated errors which may change frequently. It was felt, that concept development of architects learning to use computer-aided drawing programs would show such levels. Preliminary studies made at the U.S. Army Construction Engineering Research Laboratory upon selected subjects using computer-aided lessons in AutoCAD as a basis for observations reveal several categories of errors in using computer-aided design. These case studies show that the design process can be enhanced by automated drawing and design tools if the conceptual relationships are established as a part of the learning environment. Even more important, the observations show that architects have particular characteristics which differ from engineers and other CAD users. These differences require that education and software be tailored to their needs.

summary	After an introduction describing the present situation on computer- programs used in learning environments, some remarks are made on what future programs should look like. Although the design and the building process are both extremely complex, a proposal is made to carry out a project in a joint effort among ECAADE members to achieve a new generation of learning tools. These tools should also be of good service in a consulting environment.

title	A Format for a Graphical Communications Protocol
source	IEEE Computer Graphics and Applications vol. 6.no. 3 (March, 1986): pp. 52-62
summary	This article describes the requirements for a graphical format on which a graphical on-line communications protocol can be based. It is argued that on-line graphical communications is similar to graphical session capture, and thus the author proposes an interactive graphical communications format using the GKSM session metafile. The discussion includes items that complement the GKSM metafile such as a format for on-line interactive exchange. One key application area of such a format is multimedia on-line conferencing. Therefore, a conferencing software architecture for processing the proposed format is presented. This format specification is made available to those planning multimedia conferencing systems

title	Three-dimensional Input and Visualization
source	Computer-Aided Architectural Design Futures [CAAD Futures Conference Proceedings / ISBN 0-408-05300-3] Delft (The Netherlands), 18-19 September 1985, pp. 68-84
summary	The aim of this chapter is to investigate techniques by which man-computer interaction could be improved, specifically in the context of architectural applications of CAD. In this application the object being designed is often an assembly of defined components. Even if the building is not actually fabricated from such components, it is usually conceptualized in these terms. In a conventional graphics- based CAD system these components are usually represented by graphical icons which are displayed on the graphics screen and arranged by the user. The system described here consists of three- dimensional modelling elements which the user physically assembles to form his design. Unlike conventional architectural models which are static (i.e. cannot be changed by the users) and passive (i.e. cannot be read by a CAD system), this model is both 'user generated' and 'machine readable'. The user can create, edit and view the model by simple, natural modelling activities and without the need to learn complex operating commands often associated with CAD systems. In particular, the user can view the model, altering his viewpoint and focus of attention in a completely natural way. Conventional computer graphics within an associated CAD system are used to represent the detailed geometry which the different three-dimensional icons may represent. In addition, computer graphics are also used to present the output of the performance attributes of the objects being modelled. In the architectural application described in this chapter an energy- balance evaluation is displayed for a building designed using the modelling device. While this system is not intended to offer a completely free-form input facility it can be considered to be a specialist man-machine interface of particular relevance to architects or engineers.

title	From 2D Base Map To 3D City Model
source	UMDS '02 Proceedings, Prague (Czech Republic) 2-4 October 2002, I.17-I.28
summary	Since 1997 Helsinki City Survey Division has proceeded in experimenting and in developing the methods for converting and supplementing current digital 2D base maps in the scale 1:500 to a 3D city model. Actually since 1986 project areas have been produced in 3D for city planning and construction projects, but working with the whole map database started in 1997 because of customer demands and competitive 3D projects. 3D map database needs new data modelling and structures, map update processes need new working orders and the draftsmen need to learn a new profession; the 3D modeller. Laser-scanning and digital photogrammetry have been used in collecting 3D information on the map objects. During the years 1999-2000 laser-scanning experiments covering 45 km2 have been carried out utilizing the Swedish TopEye system. Simultaneous digital photography produces material for orto photo mosaics. These have been applied in mapping out dated map features and in vectorizing 3D buildings manually, semi automatically and automatically. In modelling we use TerraScan, TerraPhoto and TerraModeler sw, which are developed in Finland. The 3D city model project is at the same time partially a software development project. An accuracy and feasibility study was also completed and will be shortly presented. The three scales of 3D models are also presented in this paper. Some new 3D products and some usage of 3D city models in practice will be demonstrated in the actual presentation.

title	CAD and Management of Construction Projects
source	Journal of Construction Engineering and Management, Vol. 112, December, pp. 557-565
summary	The increasing interest in computer-aided design (CAD) has prompted research that is aimed at identifying the opportunities for construction managers and building contractors. It has been found that the use of CAD systems in the U.K. is mainly confined to the production of detailed drawings. Indeed, most of the systems used are 2-D drafting tools and incapable of supporting the integration of even modest amounts of nongraphical (construction) data. On the other hand, many 3-D modeling systems have the potential to integrate construction data, although they appear to be almostignored. The use of 3-D modeling systems is considered to be the most suitable vehicle for successfully integrating these data. However, this is likely to necessitate the introduction of separate databases, preferably of the relational type. The use of 3-D modeling systems in assessing the construction implications of outline designs also presents interesting possibilities and is discussed.

title	Knowledge-based Design Optimization
source	IAAI'86 Conference. 1986. pp. i:4:1-14
summary	CADLINE has abstract only. Optimization is a well understood process in design domains. A designer formulates the design problem as a single criterion or multicriteria optimization problem and then selects an appropriate optimization algorithm to search for the optimal values for the design variables. The formulation and algorithm selection procedures have been considered to be activities which relied on substantive human knowledge. This paper describes a computer system, OPTIMA, which formulates design optimization problems from a pseudo-English description into canonical algebraic expressions. It then recognizes the formulation and selects appropriate algorithm(s) for their solutions. Finally, it runs the selected algorithm(s) and sends the results to the original descriptions. Areas of expert knowledge involved in carrying out the above tasks are identified. Such knowledge is explicitly encoded in the systems. The basic philosophy and key features of the system are described and are illustrated by examples

summary	In applying optimization methodology to engineering design, a considerable amount of knowledge is utilized to construct and solve mathematical design models. However, computer based systems to assist this process have concentrated mainly on the numeric computational aspects of the process. This paper outlines a computer system which uses a knowledge-based systems approach to formulate and recognize design optimization problems. Areas of expert knowledge involved in mathematical design modeling and optimization are identified. Such knowledge is encoded explicitly in the system. An example is presented

summary	This study has been carried out during the Course of Ergotecnica Edile hold at the Instituto Dipartimentale di Architettura e Urbanistica of Catania University, and it has been addressed to the students of the Faculty of Civil Engineering (manufacturing and direction of civil works). The present study aims at instructing the students as refers to planning, through computers, erecting yards. Work-planning is specifically important with reference both to the starting program and to the carrying on of the work. Within this context, workplanning is useful as regard the control and contingent correction of the work. In the latter case, divergencies between work-evolution and forecast are of primary value.

source	Teaching and Research Experience with CAAD [4th eCAADe Conference Proceedings] Rome (Italy) 11-13 September 1986, pp. 167-179
summary	Any applied research, no matter what discipline is concerned, needs affined and suitable tools; as regards the studies in the field of architecture and planning, the use of automatic systems of analysis, data ordering and comparison is of particular interest. The quickness of operations by means of computers and the corresponding graphical representation gives new possibilities for scientific work, once impossible, not certainly because of conceptual limits, but practically, for the limits of available tools. It is the wideness of applications of computers to be pointed out, for although studied for scientific reasons, their practical usefulness is often enormous. This has been generally verified. It guilts in particular for the CAD System, proposed and explained in this paper. The practical utility this and other systems from the same field have for the public administration, contractors and consultants is well known and therefore not necessary to be described further. The use of such systems is particularly convenient in those sectors where the graphical representation is the basic part of the production process.
