title Quantitative constructability analysis with a neuro-fuzzy knowledge-based multi-criterion decision support system
source Automation in Construction 8 (5) (1999) pp. 553-565
summary This paper presents a multi-criterion decision model for quantitative constructability analysis based on a neuro-fuzzy knowledge-based system. The traditional constructability definition is modified so that constructability can be quantified, measured, and improved. A multi-layer information aggregation network is proposed to incorporate the manager's subjective preference information. The constructor's technology management policy can be reflected in the constructability evaluation process based on technology implementation preferences. A systematic approach to constructability problem detection and constructability improvement is developed to improve technology performance. Two examples of constructability analyses for alternative concrete formwork technologies are given to demonstrate the functions of the proposed methodology.

title Some Phenomena of Spatial Characteristics of Cyberspace
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 "Space," which has long been an important concept in architecture (Bloomer & Moore, 1977; Mitchell, 1995, 1999), has attracted interest of researchers from various academic disciplines in recent years (Agnew, 1993; Benko & Strohmayer, 1996; Chang, 1999; Foucault, 1982; Gould, 1998). Researchers from disciplines such as anthropology, geography, sociology, philosophy, and linguistics regard it as the basis of the discussion of various theories in social sciences and humanities (Chen, 1999). On the other hand, since the invention of Internet, Internet users have been experiencing a new and magic "world." According to the definitions in traditional architecture theories, "space" is generated whenever people define a finite void by some physical elements (Zevi, 1985). However, although Internet is a virtual, immense, invisible and intangible world, navigating in it, we can still sense the very presence of ourselves and others in a wonderland. This sense could be testified by our naming of Internet as Cyberspace -- an exotic kind of space. Therefore, as people nowadays rely more and more on the Internet in their daily life, and as more and more architectural scholars and designers begin to invest their efforts in the design of virtual places online (e.g., Maher, 1999; Li & Maher, 2000), we cannot help but ask whether there are indeed sensible spaces in Internet. And if yes, these spaces exist in terms of what forms and created by what ways?To join the current interdisciplinary discussion on the issue of space, and to obtain new definition as well as insightful understanding of "space", this study explores the spatial phenomena in Internet. We hope that our findings would ultimately be also useful for contemporary architectural designers and scholars in their designs in the real world.As a preliminary exploration, the main objective of this study is to discover the elements involved in the creation/construction of Internet spaces and to examine the relationship between human participants and Internet spaces. In addition, this study also attempts to investigate whether participants from different academic disciplines define or experience Internet spaces in different ways, and to find what spatial elements of Internet they emphasize the most.In order to achieve a more comprehensive understanding of the spatial phenomena in Internet and to overcome the subjectivity of the members of the research team, the research design of this study was divided into two stages. At the first stage, we conducted literature review to study existing theories of space (which are based on observations and investigations of the physical world). At the second stage of this study, we recruited 8 Internet regular users to approach this topic from different point of views, and to see whether people with different academic training would define and experience Internet spaces differently.The results of this study reveal that the relationship between human participants and Internet spaces is different from that between human participants and physical spaces. In the physical world, physical elements of space must be established first; it then begins to be regarded as a place after interaction between/among human participants or interaction between human participants and the physical environment. In contrast, in Internet, a sense of place is first created through human interactions (or activities), Internet participants then begin to sense the existence of a space. Therefore, it seems that, among the many spatial elements of Internet we found, "interaction/reciprocity" either between/among human participants or between human participants and the computer interface seems to be the most crucial element.In addition, another interesting result of this study is that verbal (linguistic) elements could provoke a sense of space in a degree higher than 2D visual representation and no less than 3D visual simulations. Nevertheless, verbal and 3D visual elements seem to work in different ways in terms of cognitive behaviors: Verbal elements provoke visual imagery and other sensory perceptions by "imagining" and then excite personal experiences of space; visual elements, on the other hand, provoke and excite visual experiences of space directly by "mapping".Finally, it was found that participants with different academic training did experience and define space differently. For example, when experiencing and analyzing Internet spaces, architecture designers, the creators of the physical world, emphasize the design of circulation and orientation, while participants with linguistics training focus more on subtle language usage. Visual designers tend to analyze the graphical elements of virtual spaces based on traditional painting theories; industrial designers, on the other hand, tend to treat these spaces as industrial products, emphasizing concept of user-center and the control of the computer interface.The findings of this study seem to add new information to our understanding of virtual space. It would be interesting for future studies to investigate how this information influences architectural designers in their real-world practices in this digital age. In addition, to obtain a fuller picture of Internet space, further research is needed to study the same issue by examining more Internet participants who have no formal linguistics and graphical training.

title A software industry perspective on AEC information models for distributed collaboration
source Automation in Construction 8 (3) (1999) pp. 237-248
summary This paper focuses on information modeling and computing technologies that are most relevant to the emerging software for the Architecture, Engineering, and Construction (AEC) industry. After a brief introduction to the AEC industry and its present state of computer-based information sharing and collaboration, a set of requirements for AEC information models are identified. Next, a number of key information modeling and standards initiatives for the AEC domain are briefly discussed followed by a review of the emerging object and Internet technologies. The paper will then present our perspective on the challenges and potential directions for using object-based information models in a new generation of AEC software systems intended to offer component-based open architecture for distributed collaboration.

title AI and Regional Architecture

summary In 1976 Richard Foqu established periods in the development of methods of designing. The first stage (the 50's and early 60's) - automatization of the designing process - properly identified language of description that is understood by a machine is vital. Christopher Alexander publishes 'Pattern Language'. The second stage (late 60's) - the use of the Arts - research techniques as interview, questionnaire, active observation; ergonomic aspects are also taken into consideration. The third stage (starts at the turn of the 60's and 70's) - co-participation of all of the parties involved in the designing process, and especially the user. The designing process becomes more complex but at the same time more intelligible to a non-professional - Alexander's 'Pattern Language' returns. It's been over 20 years now since the publication of this work. In the mid 70's prototypes of integrate building description are created. We are dealing now with the next stage of the designing methods development. Unquestionable progress of computer optimalization of technical and economical solutions has taken place. It's being forecasted that the next stage would be using computer as a simulator of the designing process. This stage may be combined with the development of AI. (Already in 1950 Alan Turing had formulated the theoretical grounds of Artificial Intelligence.) Can the development of the AI have the influence on the creation of present time regional architecture? Hereby I risk a conclusion that the development of AI can contribute to the creation of modern regional architecture.
