title	Capturing Designer Expertise : The CGEN System
source	18 p. : ill Pittsburgh, PA: Engineering Design Research Center, CMU, August, 1989. EDRC 18-08-89. includes bibliography.
summary	Knowledge-based systems are becoming pervasive in the computer-aided design area. For these systems to achieve satisfactory levels of performance large amounts of knowledge are necessary. However, the acquisition of knowledge is a difficult and tedious task. Automated knowledge-acquisition tools (AKAT) provide capabilities for quickly building and maintaining knowledge-bases. This paper describes the CGEN AKAT, which allows hardware designers, unfamiliar with artificial intelligence programming techniques, to deposit their expertise into a synthesis tool's knowledge-base. A set of experiments which tested CGEN's capabilities are presented. The experiments show that with CGEN hardware designers can produce high quality knowledge-bases

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	Knowledge-based Design Systems in Architecture : a Linguistic Perspective
source	Knowledge Based Systems in Architecture. Helsinki: Acta Polytechnica Scandinavica, 1989. pp. 27-36
summary	The separation of syntax and semantics in systems for the production of architectural designs is discussed. In producing designs we are less interested in mapping between buildings and their meaning than in mapping between an intended meaning and a design description of a kind that can be constructed, a mapping between semantic and syntactic realms. The thesis of this paper is that it is both feasible and operationally useful to separate the consideration of interpretation and syntactic generating in design. The authors first examine the possibility of operating in the syntactic realm, then the possibility of operating in the interpretative realm. Finally they examine how a design system might combine interpretative and syntactic systems

title	A Study of Human Performance in Computer-Aided Architectural Design
source	International Journal of Human-Computer Interaction. 1989. vol. 1: pp. 69-107 : ill. includes bibliography
summary	This paper describes the development and application of a cognitively-based performance methodology for assessing human performance on computer-aided architectural design (CAAD) tasks. Two CAAD tasks were employed that were hypothesized to be different in terms of the underlying cognitive processes required for these tasks to be performed. Methods of manipulating task complexity within each of these tasks were then developed. Six architectural graduate students were trained on a commercially available CAAD system. Each student performed the two experimental design tasks at one of three levels of complexity. The data collected included protocols, video recordings of the computer screen, and an interactive script (time-stamped record of every command input and the computers textual response). Performance measures and methods of analysis were developed which reflected the cognitive processes used by the human during design (including problem- solving techniques, planning times, heuristics employed, etc.) and the role of the computer as a design aid. The analysis techniques used included graphical techniques, Markov process analysis, protocol analysis, and error classification and analysis. The results of the study indicated that some measures more directly reflected human design activity while others more directly reflected the efficiency of interaction between the computer and the human. The discussion of the results focuses primarily on the usefulness of the various measures comprising the performance methodology, the usefulness of the tasks employed including methods for manipulating task complexity, and the effectiveness of this system as well as CAAD systems in general for aiding human design processes

title	Designing with Diagrams: A Role for Computing in Design Education and Exploration
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. 107-122
summary	Environmental designers, design educators and design students using computers are a constituency with a set of requirements for database structure and flexibility, for knowledge representation and inference mechanisms, and for both graphical and non-graphical operations, that are now articulatable and to-date largely unmet. This is especially so in the area called 'preliminary' or 'schematic' design, where our requirements are related to, but different from, those of our colleagues in mechanical and electrical engineering, whose needs have dominated the notable developments in this area. One manifestation of these needs is in the peculiar form of graphics called diagrams , and the ways in which environmental designers (architects, landscape architects., urban designers) use them. Our diagrams are both similar to and different from structural, circuit, or logical diagrams in important ways. These similarities and differences yield basic insights into designing and design knowledge, and provide guidance for some necessary steps in the development of the next generation of CAD systems. Diagrams as a form of knowledge representation have received little scrutiny in the literature of graphic representation and computer graphics. In the following sections I present an overview of the theoretical basis for distinguishing and using diagrams; examine some of the computational requirements for a system of computer-aided diagramming; describe a prototype implementation called CBD (Constraint Based Diagrammer) and illustrate one example of its use; and speculate on the implications and potential applications of these ideas in computer-aided design education.

title	SEED: A Software Environment to Support the Early Phases in Building Design
source	Proceeding of IKM '94, Weimar, Germany, pp. 5-10
summary	The SEED project intends to develop a software environment that supports the early phases in building design (Flemming et al., 1993). The goal is to provide support, in principle, for the preliminary design of buildings in all aspects that can gain from computer support. This includes using the computer not only for analysis and evaluation, but also more actively for the generation of designs, or more accurately, for the rapid generation of design representations. A major motivation for the development of SEED is to bring the results of two multi-generational research efforts focusing on `generative' design systems closer to practice: 1. LOOS/ABLOOS, a generative system for the synthesis of layouts of rectangles (Flemming et al., 1988; Flemming, 1989; Coyne and Flemming, 1990; Coyne, 1991); 2. GENESIS, a rule-based system that supports the generation of assemblies of 3-dimensional solids (Heisserman, 1991; Heisserman and Woodbury, 1993). The rapid generation of design representations can take advantage of special opportunities when it deals with a recurring building type, that is, a building type dealt with frequently by the users of the system. Design firms - from housing manufacturers to government agencies - accumulate considerable experience with recurring building types. But current CAD systems capture this experience and support its reuse only marginally. SEED intends to provide systematic support for the storing and retrieval of past solutions and their adaptation to similar problem situations. This motivation aligns aspects of SEED closely with current work in Artificial Intelligence that focuses on case-based design (see, for example, Kolodner, 1991; Domeshek and Kolodner, 1992; Hua et al., 1992).

title	Integration of case-based reasoning and model-based reasoning for adaptive design problem solving
source	Ohio State University
summary	In the case-based approach to design, a novel problem is solved by adapting a design known to solve a related problem. Adapting a known design to solve a related problem by the commonly used methods of heuristic association and search, however, can be computationally expensive if the adaptation search space is not small. The adaptation space, then, needs to be decomposed into smaller and simpler spaces that can be searched more efficiently and effectively. The knowledge for decomposing the adaptation search space can be represented as a behavior-structure model that specifies how the structure of the known design results in its output behaviors. This research investigates the use of such behavior-structure models for adapting the designs of physical devices. Comprehension of how the output behaviors of a design arise from its structure is represented as a behavioral component-substance model for the design. The model explicitly specifies (i) the expected output behaviors of the design including its functions, (ii) the elementary structural and behavioral interactions between components and substances constituting the structure of the design, and (iii) the internal causal behaviors of the design that compose the elementary interactions into its output behaviors. The causal behaviors of the design, in this model, are indexed by the expected output behaviors for which they are responsible. The model aids case-based design in several ways. First, it identifies conceptual primitives for specifying the functions of designs, which are used to index the known designs stored in a case-based memory. Second, it identifies elementary types of behavior transformations and elementary types of structure modifications. Third, it provides knowledge for decomposition of the adaptation search space into smaller spaces so that the search for the needed structure modifications is localized. Fourth, it leads to a novel method for simulating the behavioral effects of structure modifications. The output and causal behaviors of the modified design, in this method, are derived by revising the output and causal behaviors of the known design. This integrative approach unifies case-based methods, associative methods, heuristic search methods, decomposition methods, and model-based methods into one architecture for adaptive design problem solving. Core portions of this approach have been implemented in an experimental design system called KRITIK.

title	Hierarchical Design Synthesis : The M1 System
source	Pittsburgh: Engineering Design Research Center, September, 1989. 22 p. : ill. tables. includes bibliography
summary	Rapid advances in semiconductor technology are motivating the development of computer-aided design tools to assist human designers at the higher levels of the design process. In particular, there is a need for tools that aid system-level design synthesis - the process of producing a detailed artifact satisfying high level specifications given a set of components. A knowledge-based approach that uses a hierarchical design synthesis methodology is described. M1 is a knowledge-based system that implements the approach for the domain of single board computer design. A set of experiments which indicate M1's capabilities and the effectiveness of the approach in organizing and utilizing knowledge are presented

summary	Computer assistants to building process management are not able nowadays to efficiently work out the problems generated by the increased complexity of designing. Actual difficulties depend, on one hand, on the fact D.B.M.S. that have been developed on other environments than CAAD, and on the other hand, on the fact that architectural design process is scarcely formalized. At the Department of T.E.C.A., at the University of Rome, a PhD research program is aimed to overcome difficulties, working out techniques of information management based on Knowledge Engineering and particularly on Knowledge Base Management Systems and Expert Database Systems. At present a prototype system is being developed, that can manage existing technical information, connected with buiIding process.

title	A Case Study in Knowledge-Based System Development : Envelope Design for Reduction of Traffic Noise Transmission
source	February, 1990. 19 p. : some ill. and table. includes a bibliography
summary	Researchers have demonstrated the value of replication of research and explicit testing of concepts in artificial intelligence (Ritchie and Hanna 1989). In this study, a rule- based system was implemented as an exercise in the application of the theory and practice of knowledge-based systems development to architectural design analysis. The test domain was the selection of wall and window assemblies to provide adequate noise reduction given a set of traffic and building site conditions. This domain was chosen for two reasons: (1) considerable detailed heuristic information was available; and (2) it avoided large solutions spaces, 'errorful' and time-dependent data, and unreliable knowledge. Development of the system in conjunction with an extensive literature review revealed that publications on construction and performance of rule-based systems provided insufficient detail on key aspects of system architecture. Topics suffering from neglect or insufficiently rigorous treatment included algorithms used in automated inference, methods for selection of inference procedures, the integration of numerical and symbolic processing, the formulation of explanation mechanisms to deal with integrated numerical and symbolic processing, testing methods, and software standardization. Improving the quality and scope of knowledge in these areas is essential if expert systems are to be applied effectively in architectural design

title	Supporting Reflection-in-Action in the Janus Design Environment
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. 247-259
summary	We have developed a computer-based design aid called Janus, which is based on a model of computer-supported design that we think has significance for the future of architectural education. Janus utilizes a knowledge-based approach to link a graphic construction system to hypertext. This allows the computer to make useful comments on the solutions that students construct in a CAD-like environment. These comments contain information intended to make students think more carefully about what they are doing while they are doing it. In other words, Janus promotes what Donald Schon has called "reflection-inaction" (Schon, 1983). The Janus design environment is named for the Roman god with a pair of faces looking in opposite directions. In our case the faces correspond to complementary design activities we call construction and argumentation. Construction is the activity of graphically creating the form of the solution e.g., a building. Traditionally this has been done with tracing paper, pencils, and pens. Argumentation is the activity of reasoning about the problem and its solution. This includes such things as considering what to do next, what alternative courses of action are available, and which course of action to choose. Argumentation is mostly verbal but partly graphical.

summary	Innovative and creative design occurs when fragments of previous design episodes are retrieved and incorporated into the present design context. This paper presents an implementable approach to innovative and creative design based on notions of prototypes and instances within a dynamic memory model of episodic memory. Innovative and creative design are defined in terms of operators. The requirements of a reasoning system to support these classes of design activity are outlined. Examples of the processes are presented

title	Top-Down Knowledge-Based Design

summary	Traditional computer drafting systems and three- dimensional geometric modeling systems work in bottom-up fashion. They provide a range of graphic primitives, such as vectors, arcs, and splines, together with operators for inserting, deleting, combining, and transforming instances of these. Thus they are conceptually very similar to word processors, with the difference that they operate on two- dimensional or three-dimensional patterns of graphic primitives rather than one-dimensional strings of characters. This sort of system is effective for input and editing of drawings or models that represent existing designs, but provides little more help than a pencil when you want to construct from scratch a drawing of some complex object such as a human figure, an automobile, or a classical column: you must depend on your own knowledge of what the pieces are and how to shape them and put them together. If you already know how to draw something then a computer drafting system will help you to do so efficiently, but if you do not know how to begin, or how to develop and refine the drawing, then the efficiency that you gain is of little practical consequence. And accelerated performance, flashier color graphics, or futuristic three-dimensional modes of interaction will not help with this problem at all. By contrast, experienced expert graphic artists and designers usually work in top-down fashion-beginning with a very schematic sketch of the whole object, then refining this, in step-by-step fashion, till the requisite level of precision and completeness is reached. For example, a figure drawing might begin as a "stick figure" schema showing lengths and angles of limbs, then be developed to show the general blocking of masses, and finally be resolved down to the finest details of contour and surface. Similarly, an architectural drawing might begin as a parti showing just a skeleton of construction lines, then be developed into a single-line floor plan, then a plan showing accurate wall thicknesses and openings, and finally a fully developed and detailed drawing.

title	A Primitive-Instancing Interactive 3-D Modeling System for Spatial Design Studies
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. 457-468
summary	The authors have developed a basic, interactive, primitive-instancing 3-D modeling system (CAADF), which is based on a high-speed 3-D color graphic workstation, and have tested its potential ability to support spatial design studies in an architectural design studio. After- a review of work performed by a student with the system, this paper concludes that this system provides an attractive environment for spatial design studies which conventional CAD systems have not achieved. The interactive process of 3-D modeling in perspective or isometric view images and the dynamic viewing utility are the most successful features of the system. In contrast to those advantages, the resolution of color graphic display is a limitation of the system. The authors conclude that if sufficiently many appropriate 3-D geometric primitives are supported by a CAD system, a primitive instancing method can significantly reduce the work entailed in object modeling.

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. 187-199
summary	The concept of a knowledge based design shell is proposed as a basis for teaching design. The significance of the concept of design shell is discussed with respect to formalization, implementation, application and operation. GPRS-a generative prototype refinement design shell-is proposed, defined and elaborated. A plan type is introduced as one significant kind of structure of knowledge in architectural design is introduced. A method for representing syntactic and the semantic content to be used in design refinement is proposed. The method exploits the characteristics of both rules and frames, and integrates them in a prototype-based design system. This is demonstrated in a system called PRODS. Finally, the significance of such an approach in teaching is discussed.

summary	A primary aim of the Light Table project was to see if a combination of the optical laser disc, local area networks, and interactive videographic workstation technology could bring a major visual collection, (such as the Rotch Visual Collections of the Massachusetts Institute of Technology), to a campuswide population of undergraduate users. VIS (Visual Information System) is the name being given to the new genre of information technology. Much research and development effort is currently being applied to areas where the image has a special significance, for example in architecture and planning, in graphic and fine arts, in biology, in medicine, and in photography. One particular advance in the technology of VIS has been the facility to access visual information across a distributed computer system via LAN (Local Area Networks) and video delivery systems, (such as campus TV cable). This advance allows users to retrieve images from both local and remote sources, dispatching the image search through the LAN, and receiving the images back at their workstation via dedicated channels on the campus TV cable. Light Table is the title of a system that acts as a computer-based interactive videographic interface to a variety of visual information systems described in the body of this paper. It takes its name from the traditional, back- lit, translucent light table that lecturers use to assemble and view collections of slides for talks and seminars. The component of Light Table which is being reported in greatest detail here, a software outcome called Galatea, is a versatile and robust system capable of controlling video devices in a networked environment.

title	Toward a procedure of computer simulation in the restoration of historical architecture

summary	In the field of architectural design, “visualization¨ generally refers to some media, communicating and representing the idea of designers, such as ordinary drafts, maps, perspectives, photos and physical models, etc. (Rahman, 1992; Susan, 2000). The main reason why we adopt visualization is that it enables us to understand clearly and to control complicated procedures (Gombrich, 1990). Secondly, the way we get design knowledge is more from the published visualized images and less from personal experiences (Evans, 1989). Thus the importance of the representation of visualization is manifested.Due to the developments of computer technology in recent years, various computer aided design system are invented and used in a great amount, such as image processing, computer graphic, computer modeling/rendering, animation, multimedia, virtual reality and collaboration, etc. (Lawson, 1995; Liu, 1996). The conventional media are greatly replaced by computer media, and the visualization is further brought into the computerized stage. The procedure of visual impact analysis and assessment (VIAA), addressed by Rahman (1992), is renewed and amended for the intervention of computer (Liu, 2000). Based on the procedures above, a great amount of applied researches are proceeded. Therefore it is evident that the computer visualization is helpful to the discussion and evaluation during the design process (Hall, 1988, 1990, 1992, 1995, 1996, 1997, 1998; Liu, 1997; Sasada, 1986, 1988, 1990, 1993, 1997, 1998). In addition to the process of architectural design, the computer visualization is also applied to the subject of construction, which is repeatedly amended and corrected by the images of computer simulation (Liu, 2000). Potier (2000) probes into the contextual research and restoration of historical architecture by the technology of computer simulation before the practical restoration is constructed. In this way he established a communicative mode among archeologists, architects via computer media.In the research of restoration and preservation of historical architecture in Taiwan, many scholars have been devoted into the studies of historical contextual criticism (Shi, 1988, 1990, 1991, 1992, 1995; Fu, 1995, 1997; Chiu, 2000). Clues that accompany the historical contextual criticism (such as oral information, writings, photographs, pictures, etc.) help to explore the construction and the procedure of restoration (Hung, 1995), and serve as an aid to the studies of the usage and durability of the materials in the restoration of historical architecture (Dasser, 1990; Wang, 1998). Many clues are lost, because historical architecture is often age-old (Hung, 1995). Under the circumstance, restoration of historical architecture can only be proceeded by restricted pictures, written data and oral information (Shi, 1989). Therefore, computer simulation is employed by scholars to simulate the condition of historical architecture with restricted information after restoration (Potier, 2000). Yet this is only the early stage of computer-aid restoration. The focus of the paper aims at exploring that whether visual simulation of computer can help to investigate the practice of restoration and the estimation and evaluation after restoration.By exploring the restoration of historical architecture (taking the Gigi Train Station destroyed by the earthquake in last September as the operating example), this study aims to establish a complete work on computer visualization, including the concept of restoration, the practice of restoration, and the estimation and evaluation of restoration.This research is to simulate the process of restoration by computer simulation based on visualized media (restricted pictures, restricted written data and restricted oral information) and the specialized experience of historical architects (Potier, 2000). During the process of practicing, communicates with craftsmen repeatedly with some simulated alternatives, and makes the result as the foundation of evaluating and adjusting the simulating process and outcome. In this way we address a suitable and complete process of computer visualization for historical architecture.The significance of this paper is that we are able to control every detail more exactly, and then prevent possible problems during the process of restoration of historical architecture.

summary	Key parameter of a reasoning process supporting real time performance is the use of active heuristics that facilitate the achievement of goals in a timely manner (Dodiawala et al. 1989). A real time approach should incorporate speed, timeliness and adaptation during the execution of tasks. Speed and efficient knowledge processing are addressed for the solution of complex building engineering problems, such as the calibration of Building Energy Models (BEM) to the actual performance data. During retrofit projects, calibrated BEM models aid the design process, and provide a solid base for performative assessments. Despite the demand for building performance evaluations, BEM calibration remains a work-intensive task (Lam et al. 2014). This study proposes a time efficient framework for BEM calibration input data management based on the methodology of a blackboard artificial intelligence knowledge processing system. The resulting model was used for sequential data mining for the energy assessment during the renovation of a commercial building.
