title Spatial Database for Model Analysis Methods
source CAADRIA ‘98 [Proceedings of The Third Conference on Computer Aided Architectural Design Research in Asia / ISBN 4-907662-009] Osaka (Japan) 22-24 April 1998, pp. 203-212
summary In the field of architectural and urban planning and design, computer education needs to move beyond basic computer literacy and have more emphasis placed on special subjects related to planning and design. How to manage spatial data is becoming an essential issue for research and education in planning and design especially in the analysis and evaluation phases. This paper discusses the importance of spatial data in planning education and shows how a common spatial database for model analysis methods was constructed at the University of Tsukuba. The database consists of many geographical and statistical data files classified under the standard region mesh codes and covers the whole country from global areas to local areas. Web-based instructions about how to use the database have also been prepared which enable students to study practical spatial analysis by themselves.

title The visual harmony between new and old materials in the restoration of historical architecture: A study of computer simulation
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 the research of historical architecture restoration, scholars respectively focus on the field of architectural context and architectural archeology (Shi, 1988, 1990, 1991, 1992, 1995; Fu, 1995, 1997; Chiu, 2000) or on architecture construction and the procedure of restoration (Shi, 1988, 1989; Chiu, 1990). How to choose materials and cope with their durability becomes an important issue in the restoration of historical architecture (Dasser, 1990; Wang, 1998).In the related research of the usage and durability of materials, some scholars deem that, instead of continuing the traditional ways that last for hundreds of years (that is to replace new materials with old ones), it might be better to keep the original materials (Dasser, 1990). However, unavoidably, some of the originals are much worn. Thus we have to first establish the standard of eliminating components, and secondly to replace identical or similar materials with the old components (Lee, 1990). After accomplishing the restoration, we often unexpectedly find out that the renewed historical building is too new that the sense of history is eliminated (Dasser, 1990; Fu, 1997). Actually this is the important factor that determines the accomplishment of restoration. In the past, some scholars find out that the contrast and conflict between new and old materials are contributed to the different time of manufacture and different coating, such as antiseptic, pattern, etc., which result in the discrepancy of the sense of visual perception (Lee, 1990; Fu, 1997; Dasser, 1990).In recent years, a number of researches and practice of computer technology have been done in the field of architectural design. We are able to proceed design communication more exactly by the application of some systematic softwares, such as image processing, computer graphic, computer modeling/rendering, animation, multimedia, virtual reality and so on (Lawson, 1995; Liu, 1996). The application of computer technology to the research of the preservation of historical architecture is comparatively late. Continually some researchers explore the procedure of restoration by computer simulation technology (Potier, 2000), or establish digital database of the investigation of historical architecture (Sasada, 2000; Wang, 1998). How to choose materials by the technology of computer simulation influences the sense of visual perception. Liu (2000) has a more complete result on visual impact analysis and assessment (VIAA) about the research of urban design projection. The main subjects of this research paper focuses on whether the technology of computer simulation can extenuate the conflict between new and old materials that imposed on visual perception.The objective of this paper is to propose a standard method of visual harmony effects for materials in historical architecture (taking the Gigi Train Station destroyed by the earthquake in last September as the operating example).There are five steps in this research: 1.Categorize the materials of historical architecture and establish the information in digital database. 2.Get new materials of historical architecture and establish the information in digital database. 3.According to the mixing amount of new and old materials, determinate their proportion of the building; mixing new and old materials in a certain way. 4.Assign the mixed materials to the computer model and proceed the simulation of lighting. 5.Make experts and the citizens to evaluate the accomplished computer model in order to propose the expected standard method.According to the experiment mentioned above, we first address a procedure of material simulation of the historical architecture restoration and then offer some suggestions of how to mix new and old materials.By this procedure of simulation, we offer a better view to control the restoration of historical architecture. And, the discrepancy and discordance by new and old materials can be released. Moreover, we thus avoid to reconstructing ¡§too new¡¨ historical architecture.

title Extending spatial DSS with spatial choice models of multipurpose shopping trip behaviour
source Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary Spatial choice or interaction models have been widely used in spatial DSS or customised GIS for analysing the impacts of retail location plans. The models typically used, however, do not account for spatial agglomeration effects on spatial choice behaviour. This study develops a model system for analysing the impacts of retail plans based on a choice model of multipurpose behaviour developed in earlier work. The model system is implemented in the spatial DSS called Location Planner. An empirical study demonstrates the empirical estimation and use of the model for analysing the impacts of an expansion of floor space in the major shopping centre of a middle-sized city in The Netherlands. The results indicate that agglomeration effects as predicted by the model can have substantial impacts on the performance of retail systems. Therefore, it is argued that when incorporated in a spatial DSS, the more complex models have the potential to improve the use of these systems for impact analysis.

title Balancing Computer Use and Design Content in Studio Projects
source Digital Design Studios: Do Computers Make a Difference? [ACADIA Conference Proceedings / ISBN 1-880250-07-1] Québec City (Canada) October 22-25, 1998, pp. 36-43
summary Particular design approaches must be taught in order to take advantage of the strengths of computers in design rather than attempting to make computers conform to methods developed as by-products of manual design techniques. For the last three years our team of faculty teaching the second year design studio has been trying different approaches to the use of computers in design, in order to find the advantages and opportunities especially suited to electronic media. There are several projects during the semester which use computers at different stages of the design process. One of these projects, called “A Spatial Sequence,” uses information from a previous project as well as the knowledge from the computer class in parallel to design studio. The project asked students to create spatial archetypes based on the work of well-known architects. They explore the following topics as represented in the work of one particular architect: relationships of major spaces/minor spaces, approach/entry, and transition/threshold. Following the analysis, they create digital models to explore the spaces formed by their archetypes. Before committing to a physical study model, they look at the transitions between spaces by creating a sequence using the digital model and producing a series of shots through the digital model to show the flow of spaces. The use of computer through the process accelerates the options available to explore a sequence of elements, while simultaneously giving them a window to look into the spaces they have created. This hybridized approach of precedent analysis, digital modeling, and physical modeling was uniquely suited to the studio problem.

title Visual Communication in Urban Planning and Urban Design
source Working Paper 2; Centre for Advanced Spatial Analysis Working Papers; London; June 1998
summary This Case Study documents the current status of visual communication in urban design and planning. Visual communication is examined through discussion of standalone and network media, specifically concentrating on visualisation on the World Wide Web (WWW). First, we examine the use of Solid and Geometric Modelling for visualising urban planning and urban design. This report documents and compares examples of the use of Virtual Reality Modelling Language (VRML) and proprietary WWW based Virtual Reality modelling software. Examples include the modelling of Bath and Glasgow using both VRML 1.0 and 2.0. The use of Virtual Worlds and their role in visualising urban form within multi-user environments is reviewed. The use of Virtual Worlds is developed into a study of the possibilities and limitations of Virtual Internet Design Arena's (ViDA's), an initiative undertaken at the Centre for Advanced Spatial Analysis, University College London. The use of Virtual Worlds and their development towards ViDA's is seen as one of the most important developments in visual communication for urban planning and urban design since the development plan. Secondly, the role of photorealistic media in the process of communicating plans is examined. The process of creating photorealistic media is documented, and examples of the Virtual Streetscape and Wired Whitehall Virtual Urban Interface System are provided. The conclusion is that, although the use of photo-realistic media on the WWW provides a way to visually communicate planning information, its use is limited. The merging of photorealistic media and solid geometric modelling in the creation of Augmented Reality is reviewed. Augmented Reality is seen to provide an important step forward in the ability quickly and easily to visualise urban planning and urban design information. Third, the role of visual communication of planning data through GIS is examined in terms of desktop, three dimensional, and Internet based GIS. The evolution to Internet GIS is seen as a critical component in the development of virtual cities that will allow urban planners and urban designers to visualise and model the complexity of the built environment in networked virtual reality. Finally, a viewpoint is put forward of the Virtual City, linking Internet GIS with photorealistic multi-user Virtual Worlds. At present there are constraints on how far virtual cities can be developed, but a view is provided on how these networked virtual worlds are developing to aid visual communication in urban planning and urban design.

source Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary In this paper, the integration of modelling the changes in land-use and the changes in the infrastructure network will be described. Emphasis is laid on the automatic development of the network instead of changing the network by hand before simulating the changes in the land-use pattern.The approach and working procedure were tested by developing a pilot model simulating the spatial situation on the Frisian island Ameland (The Netherlands). The pilot is developed within the geographical information system Arcinfo. In this pilot model, special attention is paid to the extension of the infrastructure network and the allocation of more than one activity. Network analysis for the purpose of network extension is based on graph theory. Selection of links is based on the increase of the total accessibility within the network system as a result of adding a link to the network. The allocation of activities is based on several selection criteria and takes place within a cellular grid. Several methods ofselecting cells and links and the choices made will be discussed.

summary Auditorium design is a complex task. Various programmatic, functional and acoustical parameters have to be resolved in the spatial design of an auditorium. This ongoing research project deals with the development of a computer-aided design system for the preliminary spatial design of proscenium type auditoriums. The concept of “acoustic sculpting” is used to generate the spatial form of the auditorium from programmatic, functional and acoustical parameters. These parameters are incorporated using a combination of mathematical, empirical and statistical methods. The generation of the spatial form of the auditorium is implemented as an algorithm that is executed on the computer. The spatial form of the auditorium generated by the system is exported as a computer model for design development and acoustical analysis.

title A Model for Integrated Spatial and Structural Design of Buildings

summary Recent advances in computer graphics and 3D user interfaces have enabled the emergence of 3D sketch modeling as a viable approach to architectural design, especially in the early schematic phase. This paper describes how a system can be built and used which integrates the capabilities of a good structural analysis system in the user-friendly working environment of a design-oriented modeling program. The structure of a building model as seen by finite element algorithms is a schematic idealization of the building's physical structure into nodes, elements, internal releases, boundary conditions, and loads. The more familiar architectural model used for design visualization represents spatial elements such as roofs, floors, walls, and windows. Rather than treat these models independently, the structural model can be defined in relation to the architectural as a virtual model with inherited common characteristics and additional relational and attribute information, using feature-based geometry data structures to organize topological intelligence in the spatial model. This provides the basis for synchronous modification of structural and architectural aspects of the design.

title A Model of Land use Conversion and Its Application
source Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary A quantitative model for analyzing the spatial distribution of land use utility is proposed. This model is based on the random bidding theory in which location behavior is decided according to the size of utility to be obtained. The utility function used here consists of the benefit and the cost in the process of land use transition. The benefit is described as the positive utility that can be obtained by doing the corresponding land use at the place. The cost is described as the negative utility that is necessary forchanging the land use from one state to the others. The most likelihood method is generally employed to estimate the parameters of this kind of models. However, we attempt to propose the other statistical method through the mathematical consideration. Using this model, it is possible to obtain the spatial distribution of land use utility that differs with the places and with the land use states. We can also evaluate the effects of a change of land-price or construction costs on our utility. Namely, our locationbehavior can be estimated numerically relating with the social or economic factors. As numerical examples, we apply the proposed model to the actual land use data and access the effectiveness of the model.

summary Location is often considered as the most important factor leading to the success of public or private services. Location is the key in maximising accessibility and keeping operating cost low. A collaborative research project between ‘Nottingham University’ and the ‘Environmental ServicesDepartment of Nottingham City Council’ is developing an ‘Intelligent Map’ for identifying optimum locations for the recycling centres in the city. The object is to develop a new decision support system for urban planners, to be used as a management and analytical tool for improving locational decisionmaking. This paper discusses the technique of the Intelligent Map, and its concept. The paper includes three main sections. The first discusses the introduction of the mini-recycling centres in Nottingham, theproblems associated with their spatial distribution, and the need for a new decision support system using GIS technology. The second examines traditional techniques using GIS for identifying optimum locations and calculating catchment areas. The third explains the concept of the Intelligent Map; discussion takes the form of an initial analysis of the likely method to be applied, and then briefly outlines some of the prototyping work that is currently taking place at Nottingham.

title Conceptual Structural Design Through Knowledge Hierarchies
source Carnegie Mellon University, Department of Civil and Environmental Engineering, Pittsburgh
summary Computer support for conceptual design still lags behind software available for analysis and detailed design. The Software Environment to Support the Early Phases in Building Design (SEED) project has the goal of providing design generation and exploration capabilities to aid in the conceptual design of buildings, from architectural programming and layout to enclosure design and structural configuration. The current work presents a component of the efforts of the SEED-Config Structure group in providing computer support for conceptual structural design. The Building Entity and Technology (BENT) approach models data about building elements in a general, hierarchical form, where design evolution is represented by the growing specificity of the design description. Two methods of system-supported design generation are provided: case-based reasoning and application of knowledge rules. The knowledge rules, termed technologies, and how they are specified and used are the primary focus of this thesis. In the BENT approach, conceptual structural engineering knowledge is modularized into technology nodes arranged in a directed 'AND/OR' graph, where OR nodes represent alternative design decisions and AND nodes represent problem decomposition. In addition, nodes in the graph may also be specified as having AND/OR incoming arcs thus reducing the duplication of nodes and enhancing the representational power of the approach. In order to facilitate the incorporation of new knowledge into the system, and verify and/or change the knowledge already in the system, the data model and the interface allow for dynamic creation, browsing, and editing of technology nodes. Design generation through the use of the knowledge hierarchy involves the conditional application of nodes according to the design context as represented by the building element(s) under consideration. Each application of a technology node expands the design of building elements by increasing the detail of the design description or by decomposing the elements into less abstract components. In addition, support for simultaneous design of multiple elements and for iteration control are also provided. An important feature of the BENT approach is that the generative knowledge (i.e., the technology hierarchy) is detached from the information repository (i.e., the database of entities which make up the building). This allows the technology hierarchies to be used in a modular fashion from building problem to building problem.

title A design tool for analysis and visual quality control of urbanenvironments supported by object databases
source Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary In the paper, the main concepts about a design tool supported by an object database system will be described. The design tool should improve architectural design with respect to analysis and improving existing and planned urban environments regarding several quality criteria, especially those associated with visual aspects. Preconditions for defining the design tool's purpose are the determination of the "well-situated" urban elements, their impact on cognitive mapping, and the exploitation of thisknowledge on cognitive mapping for the improvement of urban environments. Cognitive mapping is a kind of representation of schematic knowledge that a person has about familiar environments. A cognitive map is stored information or knowledge about the purpose and function of the environment. This leads to the conclusion that an urban environment design which takes of the process of cognitive mapping into consideration, will be experienced by most of the people in the same way. Investigationsof this process result in a theoretical model of elements of urban environments, their relationships and their dependencies. The theoretical platform of the tool is based on design theory, cognitive science andcomputer science. Design theory and cognitive science will be used to develop the theoretical model. This theoretical model together with computer science will be the basis for tool development. The tooluses a schematic representation of urban environment, based partly on Lynch's theory of "urban form". Lynch's theory is crucial for the tool because it explains almost all elements of urban environments. Systematic investigation of urban environments and their characteristics are important for theoretical modeling as well as for the later computational modeling of the tool. The main computational support for the tool will be provided by an object database system, which helps to represent and to handle all the urban elements with their properties and relationships, with their natural semantics. The information represented in the database will be used to analyze urban environments as well as to improve andcontrol their visual quality.

summary Efficient and well-managed urban bus transport systems supported by information systems with decision support capabilities developed within the framework of an advanced Relational Data Base Management System (RDBMS) can provide critical information at the right moment and assisttransport managers in conducting performance evaluations. This paper includes discussions on the use of the entity-relationship (E-R) model (a semantic data modeling technique) in the development of thestructure of the conceptual database for the information system planned to be implemented using RDBMS. The E-R data modeling approach enables database designers in obtaining the third normal forms of related databases for the efficient functioning of the information system. The inportance of decision tables in the development of DSS modules using Expert System shells are also discussed. The DSS modules will assist transport managers in the analysis of operational performance for bus depots or the organization as a whole. The E-R diagrams generated and the decision files developed will serve as important documents that can enhance the adaptability of the DSS to the changing needs ofthe organizations. The conceptualization of the information system to support decision-making in an RDBMS framework provides the advantage of a very low 'disk seek' time and facilitates frequent generation of reports.

source Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary This paper examines the functions of local authority particularly in the context of planning and development control. The process of development control involves a technique for the systematic compilation of expert quantitative analysis and qualitative assessment of a project's land use and development viability, including its effect on the surrounding area, andthe presentation of results in a way which enables the importance of the predicted results, and the scope for modifying or mitigating them, to be properly evaluated by the relevant decision making body before a planning application decision is rendered. Taking Kuala Lumpur as an example this paper will demonstrate the development of database and its application for development and building control. The application indicates that thefunctionality of GIS can be enhanced, i.e. by adding new model and analytical tools to existing systems and by using the GIS toolkit to best effect. Consequently it will be used to assist decision-making, taking into account among other things, the current scenarios of the proposed development, physical constraint and future impacts.

title Evaluating Office Buildings with MOLCA(Model for Office Life Cycle Assessment)
source Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary MOLCA (Model for Office Life Cycle Assessment) is a project that aims to develop a tool that enables designers and builders to evaluate the environmental impact of their designs (of office buildings) from a environmental point of view. The model used is based on guidelinesgiven by ISO 14000, using the so-called Life Cycle Assessment (LCA) method. The MOLCA project started in 1997 and will be finished in 2001 resulting in the aforementioned tool. MOLCA is a module within broader research conducted at the Eindhoven University of Technology aiming to reduce design risks to a minimum in the early design stages.Since the MOLCA project started two major case-studies have been carried out. One into the difference in environmental load caused by using concrete and steel roof systems respectively and the role of recycling. The second study focused on biases in LCA data and how to handle them. For the simulations a computer-model named SimaPro was used, using the world-wide accepted method developed by CML (Centre for the Environment, Leiden, the Netherlands). With this model different life-cycle scenarios were studied and evaluated. Based on those two case studies and a third one into an office area, a first model has been developed.Bottle-neck in this field of study is estimating average recycling and re-use percentages of the total flow of material waste in the building sector and collecting reliable process data. Another problem within LCA studies is estimating the reliability of the input data and modelling uncertainties. All these topics will be subject of further analysis.

title Advanced automation or conventional construction process?
source Automation in Construction 7 (4) (1998) pp. 299-314
summary The rapidly developing area of construction automation leads construction managers to critically evaluate the feasibility of replacing conventional construction processes by automated systems. This decision requires careful analysis of tangible and intangible factors such as need-based criteria, economic criteria, technological criteria, project specific criteria, and safety/risk criteria. This paper presents a decision making model and a decision support system (DSS) to assist construction managers in systematically evaluating whether to opt for a conventional construction process or an automated system for a given project. The proposed DSS, called AUTOCOP (AUTomation Option evaluation for COnstruction Processes), utilizes the Analytical Hierarchy Method (AHP) to analyze the tangible and the intangible set of criteria involved in the decision problem.

In our thesis we intend to propose an alternative from our Industrial Design point of view, we'll explain how to avoid the problems aforementioned. For the development of this thesis we've chosen computer software from CAD systems as an instrumental methodology. These systems allowed as to develop a theoretical model of interface. The empirical foundation on which our model is based, lies on the systematic analysis of the classic technique of pressore sores prevention. In computer simulation, a flexible plate, driven by a set of actuators, defines a kinematic behavior equivalent to the one produced by classic method. Two theoretical models were used, Model 1 and Model 2. Model 2 was created as a consequence of certain functional and ergonomic disorders found in electronic 3D maquettes developed during the design of Model 1. The development of Model 2 became the significant nucleus upon which the exposition of the theoretical model was centered.

summary In a chain of "real - perceived - imagined space" the computer reduces to a uniform model of only real and imagined space. It cannot undertake man's function or it cannot build the perception model. However, perception assumes physiological perception, psychological estimation and understanding, and emotional ho-experience. For a person the seizing of space during perception is constructing temporary spatial images and their development. The communicative relations of the person with environment are established during revealing internal and external structural communications and the interior represents the message, unwrapped in space and perceived in time. The real space is formed under influence of the sum of conceptual restrictions. The character of these restrictions depends on a super idea, a type of an initial situation, character of installations and on social-cultural stereotypes of the author. Without this stage transition to real architectural object is impossible. Result of activity of an architect at this stage becomes creation hypothetical cyberspace, with its own peculiarities and laws.
