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

summary	The paper presents an approach to the problems of architectural design aided by Artificial Intelligence techniques that can solve the difficulties related to combinatorial explosion, often encountered in the past. Three expert systems, dubbed "reasoners", capable of some elementary design work and a hypothesis for their interaction have been developed. Reasoner A has an "analogical" view of space. A notion of conflict, managed by means of fuzzy logic, has been introduced. It corresponds, in an intuitive and straightforward fashion, to the common notion of conflict or contradiction in real space as a consequence of improper overlapping of actual physical objects or of their functional pertinence. Reasoner B works on formalized models of building objects. It designs new patterns from given patterns taken as defaults. Reasoner C picks up from an archive of patterns the one which best suits a list of given goals. Design is the result of interaction between the three reasoners. Finally, the proposed schema raises questions about formal structures ("images") and about the nature of culturally-linked options ("memory") on which some preliminary considerations are made. Prototypes of the reasoners are operating at the Instituto di Edilizia of the University of Ancona, Italy.

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	A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary	Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

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

doi	https://doi.org/10.52842/conf.ecaade.1989.x.u3h
source	CAAD: Education - Research and Practice [eCAADe Conference Proceedings / ISBN 87-982875-2-4] Aarhus (Denmark) 21-23 September 1989, pp. 7.3.1-7.3.9
summary	The paper presents a study aimed at the modelization of a design operation of perturbation of an architectural framework in order to comply with a series of given design specifications. A formalized representation of the building object is assumed, Artificial Intelligence techniques are adopted to work on it. It is assumed that the computer carries out deformations starting from one of these structures in order to attain to a solution consistent with project specifications. A description of the structures employed for the representation of the building body (matroids) is firstly proposed. A planning theme is then assumed, as an example, whose main feature is to maintain the outer perimeter of a dwelling, to change its internal distribution in such a way as to resemble as closely as possible to the original and yet meaningfully alter its typology.

title	The Emperor's New Mind. Concerning Computers Minds, and the Laws of Physics.
source	Oxford University Press
summary	The Emperor's New Mind, physicist Roger Penrose's 1989 treatise attacking the foundations of strong artificial intelligence, is crucial for anyone interested in the history of thinking about AI and consciousness. Part survey of modern physics, part exploration of the philosophy of mind, the book is not for casual readers--though it's not overly technical, it rarely pauses to let the reader catch a breath. The overview of relativity and quantum theory, written by a master, is priceless and uncontroversial. The exploration of consciousness and AI, though, is generally considered as resting on shakier ground. Penrose claims that there is an intimate, perhaps unknowable relation between quantum effects and our thinking, and ultimately derives his anti-AI stance from his proposition that some, if not all, of our thinking is non-algorithmic. Of course, these days we believe that there are other avenues to AI than traditional algorithmic programming; while he has been accused of setting up straw robots to knock down, this accusation is unfair. Little was then known about the power of neural networks and behavior-based robotics to simulate (and, some would say, produce) intelligent problem-solving behavior. Whether these tools will lead to strong AI is ultimately a question of belief, not proof, and The Emperor's New Mind offers powerful arguments useful to believer and nonbeliever alike

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.

summary	Simple s-plane maps are used to graphically reveal interactions of performance requirements and constraints thus providing a control system designer insight into performance trade-offs. Two well-known but powerful ideas underlie this approach: (a) the characteristic equation of an nth-order system can be fully described by the specification of n variables and (b) any dynamic performance requirement or constraint can be expressed in terms of 2n variables of which n describe the open-loop and n describe the closed-loop characteristic equations. An example illustrates the application of the approach to controller design

summary	Focusing on the tasks of university architectural education, a special stress is first laid on the possibility of going beyond some limits of traditional CAAD. as coming out from the recent debate, and on the opportunities offered by knowledge based systems as metadesign supports in architectural domains. Particularly, with regard to image-databases, their importance for explaining and exemplifying the knowledge representation in KB Systems, and their integration via intelligent interface are discussed. At last, some possible uses of the whole as an educational tool in the daily university training are proposed.

summary	The context in which designers operate is becoming more and more complex, owing to the large number of codes, new materials, technologies and professional figures; new instruments are needed, therefore, to support and verify design activity. The results obtained in the first years of 'computer era' were barely sufficient. The hardware and software available today is capable of producing a new generation of CAD systems which can aid the designer in the process of conceiving and defining building objects. At the CAD Laboratory in the Department of Building and Environmental Control Techniques at the 'La Sapienza' University of Rome, research is being carried out with the aim of defining a new kind of Knowledge-based assistant for architectural design. To this purpose a partnership has been established whit a private firm called CARTESIANA, whose partners are software houses, designing and building associations.

summary	This paper is not just about the future of computerized design practice. It is about what to do today in contemplation of tomorrow-the issues of computercentered practice and the courses of action open to us can be discerned by the careful observer. The realities of computerized design practice are different from the issues on which design education still fixes its attention. To educators, the present paper recommends further clinical research on computerized design firms and suggests that case studies on the matter be developed and utilized as teaching material. Research conducted by the author of this paper indicates that a new form of design firm is emerging-the computerized design firm-totally supported and augmented by the new information technology. The present paper proceeds by introducing an abridged case study of an actual totally electronic, computerized design practice. Then, the paper concentrates on modelling the computerized design firm as an intelligent system, indicating non-trivial changes in its structure and strategy brought about by the introduction of the new information technology into its operations - among other considerations, different strategies and diverse conceptions of management and workgroup roles are highlighted. In particular, this paper points out that these structural and strategic changes reflect back on the technology of information with pressures to redirect present emphasis on the individual designer, working alone in an isolated workstation, to a more realistic conception of the designer as a member of an electronic workgroup. Finally, the paper underlines that this non-trivial conception demands that new hardware and software be developed to meet the needs of the electronic workgroup - which raises issues of human-machine interface. Further, it raises the key issues of how to represent and expose knowledge to users in intelligent information - sharing systems, designed to include not only good user interfaces for supporting problem-solving activities of individuals, but also good organizational interfaces for supporting the problem-solving activities of groups. The paper closes by charting promising directions for further research and with a few remarks about the computerized design firm's (near) future.

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.
