title	Anticipation in Evaluation and Assessment of Urban and Regional Plans
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 order to start a move toward better computer based supporting tools for the assessment of urban and regional plans, a new research and development endeavour is proposed. In so doing, anticipation andanticipatory computing, i.e. a technique applying modelling and simulation, is found to be an interesting and promising point of departure. Hence, a fuzzy cellular automata computer model (STF) for simulation and anticipation of geographical or physical space is constructed. The main idea is to map anurban plan onto the STF for its assessing. STF has a normalised and continuous, i.e. fuzzy, system variable while both the time and space dimensions take on discrete values. Further, while ordinary cellularautomata use local rules, global ones are employed in STF, i.e. there is a total interdependence among all the cells of the automata. Outcomes of STF can be interpreted more as possible future states than exact predictions. Preliminary results seem to be well in line with main characteristics of planned urban or regional geographical spaces. Further, for the managing of multi-criteria choice situations, a fuzzy procedure – the Ordered Weighted Average (OWA) procedure – with continuous control over the degree of ANDOR-ness and with independent control over the degree of tradeoff, is proposed.

title	The use of genetic programming for applications in the field of spatial composition
source	International Conference on Generative Art
summary	Architectural design teaching using computers has been a preoccupation of CECA since 1991. All design tutors provide their students with a set of models and ways to form, and we have explored a set of approaches including cellular automata, genetic programming ,agent based modelling and shape grammars as additional tools with which to explore architectural ( and architectonic) ideas.This paper discusses the use of genetic programming (G.P.) for applications in the field of spatial composition. CECA has been developing the use of Genetic Programming for some time ( see references ) and has covered the evolution of L-Systems production rules( coates 1997, 1999b), and the evolution of generative grammars of form (Coates 1998 1999a). The G.P. was used to generate three-dimensional spatial forms from a set of geometrical structures .The approach uses genetic programming with a Genetic Library (G.Lib) .G.P. provides a way to genetically breed a computer program to solve a problem.G. Lib. enables genetic programming to define potentially useful subroutines dynamically during a run .* Exploring a shape grammar consisting of simple solid primitives and transformations. * Applying a simple fitness function to the solid breeding G.P.* Exploring a shape grammar of composite surface objects. * Developing grammarsfor existing buildings, and creating hybrids. * Exploring the shape grammar of abuilding within a G.P.We will report on new work using a range of different morphologies ( boolean operations, surface operations and grammars of style ) and describe the use of objective functions ( natural selection) and the "eyeball test" ( artificial selection) as ways of controlling and exploring the design spaces thus defined.

title	Integrated Land-Use and Network Modelling
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.

title	A methodological approach to object modelling in the architectural designprocess
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	The paper describes a first prototype constructed in search for a central object model. It presents all possible data, concepts and operations concerning the architectural design process in the early phases.A central model of the process of design is essential: going from one design phase into another, the model describes geometrical shapes, abstract concepts like space and activity, concrete physical building elements and the basic operations all these entities undertake. Emphasis is put on combining all these different viewpoints, thus enabling the designer to use a broad range of design strategies. The aim is to help him and not steer or even hamper his creative process. Information necessary toassist the user of the system concerning energy calculation, stability checks etc can be extracted. By means of appropriate interfaces not only those tests built on top of the system but also existing software packages can make use of the model’s object structure. The implemented object model is one of the cornerstones of the IDEA+ project, aiming to provide an Integrated Design Environment for Architecture.

title	Wireless communication and computing at the construction jobsite
source	Automation in Construction 7 (4) (1998) pp. 327-347
summary	For many years, the walkie-talkie has been synonymous with the construction industry. During jobsite project execution, there are three variables which can either hinder or facilitate successful results, namely, quality, quantity, and timing of information. Wireless data communications technology is capable of delivering just-in-time information within the `last mile' between the trailer and a desired location on the jobsite. This paper reports on a study which surveyed information needs at the jobsite, emerging wireless data communications technology, and assessed the extent to which wireless data technology can fulfill the information needs of the jobsite [J.M. de la Garza, I. Howitt, Wireless communication and computing at the jobsite, Research Report 136-11, Construction Industry Institute, Austin, TX, 1997]. We have organized jobsite information needs into the following ten categories: (a) requests for information, (b) materials management, (c) equipment management, (d) cost management, (e) schedule and means and methods, (f) jobsite record keeping, (g) submittals, (h) safety, (i) QC/QA, and (k) future trends. Each category was analyzed in terms of its appropriateness to take advantage of wireless technology. The four formats considered to transmit information wirelessly were: (a) live voice, (b) live video, (c) batched data, and (d) live data. Current wireless communication technology has been classified into the following five classes: (a) circuit-switched wireless data systems, (b) packet-switched wireless data systems––this class was further subdivided into specialized mobile radio systems and cellular digital packet data systems, (c) wireless local area networks, (d) paging systems, and (e) satellite-based data communications. A primer for wireless communications covering both fundamental and advanced communications concepts has also been included to enable a better understanding of the issues involved in making trade-offs while configuring a wireless jobsite communication system. The example presented in this paper shows how a contractor can define a subset of information needs by choosing from those already articulated herein and determine if a given wireless technology should even be considered as a viable way of meeting the information needs that such company has.

title	Consequences for practical aesthetics and for aesthetical theory of the insertion of principles from quantum theory in cellular automata
source	International Conference on Generative Art
summary	A cellular automaton that includes some principles from quantum theory is considered. The automaton generates forms of an aesthetic nature. At every time step, a form grows with a single cell. This cell is selected with a selection probability that is determined by an amplitude. If the algorithm is run with selection of the cell of maximal amplitude at every time step, a type of form results that is called 'platonic'. Such forms typically have higher aesthetic complexity than their non-platonic counterparts. The case of selection probabilities determined by squares of amplitudes has a strong analogy with quantum theory. This analogy is elaborated by consideration of forms that have mutual correlations. These correlations can be of a classical nature, of a quantum mechanical type, or of a type that is termed 'super-correlation'.

title	Geometric Modeling intThe Simulation of Fire - Smoke Spread in Buildings
source	II Seminario Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings / ISBN 978-97190-0-X] Mar del Plata (Argentina) 9-11 september 1998, pp. 438-445
summary	Since the performance simulation of buildings, such as fire/smoke spread, energy loss/gain, acoustics, etc. greatly rely on building geometry, the way the physical environment is modeled can substantially effect the reliability of the predictions made by such simulations. Most computer models that simulate fire and smoke spread in buildings limit the computer representation of the building to simpler geometries and define rooms as rectangular spaces or as spaces with uniform crossections. Such a definition does not account for the variety of building elements that can exist in a building such as large overhangs, half height walls, etc. Existing simulations are typically developed as mathematical models and use the principles of thermodynamics to represent the spread of the elements of fire through space over a given time period. For example, in zone models each room is defined as a two tier space with heat and smoke exchange between lower and upper tiers as the fire progresses. On the other hand, field models divide the space into small contiguous units where thermodynamic state of each unit is calculated as the simulated fire progresses. Dynamic processes such as fire and smoke spread must recognize both intangible (i.e. voids) and tangible (i.e. solids such as walls, balconies, ceiling, etc.) architectural entities. This paper explores the potential of solid modeling techniques in generating geometric definitions for both solid and void architectural entities that can interact With mathematical models of fire/smoke spread in buildings. The implications of cellular spatial partitioning techniques for zone or field models of fire/smoke spread are investigated, and the methods of creating cellular decomposftion models for architectural spaces as well as for spatial boundaries such as walls are explored. The size of each cellular partition, i.e. the resolution of the partition, and the material and heat transfer attributes of each cell were found to be very critical in modeling the spread fire through voids as well as through solids in a building.

title	A Feature-Based Description Technique for Design Processes: A Case Study
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 order to develop appropriate tools for decision support in design processes, it is necessary to found them on an understanding of design. Analytical techniques of design processes that have a direct relationship with tool development can enhance design support systems development. The paper focuses on a design support system in the VR-DIS research program. The aim of this research program is to develop insight in the architectural design process and to establish design tools for architectsworking in Virtual Reality. The basic approach for data modelling in VR in this research is based on an extension of the Feature Based Modelling paradigm taken from design in mechanical engineering. The computer model of the design in the system is a Feature-based model. This paper describes design processes in terms of changes in the Feature-based model of the design. For this purpose, a case of a house design is used. Drawings in the conceptual design phase up to the preliminary design phase arestudied. Each state of the drawings is described in terms of a Feature-model. Particular design actions such as creation of spaces, definition of architectural elements, and changes during the design process can be expressed in terms of changes in the Feature-model. Because of the use of Features, the changes can be formalised in the VR-DIS system. The description in terms of Features offers an analytical toolthat leads to a functional brief for design support tools. The paper ends with a discussion of implications and future work.

title	Changing trends and approaches in human and computer modelling for social housing policies
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	The paper discusses conceptual issues, goals and preliminary results of an on-going research which aims at building a Decision Support System for public housing environmental oriented maintenance and management in a city in Southern Italy, Bari. Traditional post-war Italian housing policies are compared with more recent approaches in the field, pointing out the change from quantitative, aggregated, more simple building problems and relatedapproaches to qualitative, differentiated, complex ones integrating social, economic and environmental dimensions with the aim of regenerating deteriorated residential areas. The paper claims for the need shift, both in the human and computer areas, from traditional quantitative models to new approaches able to manage also qualitative variables, temporal dynamics, emergencies, and intentionality, since they appear key aspects of the real world to be modelled. The housing estate of Bari and its needs of maintenance and management are examined, eliciting essential related knowledge using the interview technique. The clear orientation towards sustainable policies for urban regeneration, at a local, national, and Community level, is also considered. The innovative and collaborative nature of such policies and the attention to be paid to the social aspects ofthe problem require a complex DSS, integrating various kind of hypertexts, information systems and case-based fuzzy expert systems, whose main aims, functions, software and general organisation are outlined in the paper.

title	Java collaborative interface for architectural simulations A case study on wooden ceilings of Krakow
source	International Conference On Conservation - Krakow 2000, 23-24 November 1998, Krakow, Poland
summary	Concern for the architectural and urban preservation problems has been considerably increasing in the past decades, and with it the necessity to investigate the consequences and opportunities opened for the conservation discipline by the development of computer-based systems. Architectural interventions on historical edifices or in preserved urban fabric face conservationists and architects with specific problems related to the handling and exchange of a variety of historical documents and representations. The recent development of information technologies offers opportunities to favour a better access to such data, as well as means to represent architectural hypothesis or design. Developing applications for the Internet also introduces a greater capacity to exchange experiences or ideas and to invest on low-cost collaborative working platforms. In the field of the architectural heritage, our research addresses two problems: historical data and documentation of the edifice, methods of representation (knowledge modelling and visualisation) of the edifice. This research is connected with the ARKIW POLONIUM co-operation program that links the MAP-GAMSAU CNRS laboratory (Marseilles, France) and the Institute HAiKZ of Kraków's Faculty of Architecture. The ARKIW programme deals with questions related to the use of information technologies in the recording, protection and studying of the architectural heritage. Case studies are chosen in order to experience and validate a technical platform dedicated to the formalisation and exchange of knowledge related to the architectural heritage (architectural data management, representation and simulation tools, survey methods, ...). A special focus is put on the evolution of the urban fabric and on the simulation of reconstructional hypothesis. Our contribution will introduce current ARKIW internet applications and experiences: The ARPENTEUR architectural survey experiment on Wie¿a Ratuszowa (a photogrammetrical survey based on an architectural model). A Gothic and Renaissance reconstruction of the Ratusz Krakowski using a commercial modelisation and animation software (MAYA). The SOL on line documentation interface for Kraków's Rynek G_ówny. Internet analytical approach in the presentation of morphological informations about Kraków's Kramy Bogate Rynku Krakowskiego. Object-Orientation approach in the modelling of the architectural corpus. The VALIDEUR and HUBLOT Virtual Reality modellers for the simulation and representation of reconstructional hypothesis and corpus analysis.

title	Business objects in construct IT
source	R. Amor (ed.) Product and Process Modelling in the Building Industry, Building Research Establishment, Watford, England, pp. 117-130
summary	Objective: EU Esprit Project 25.741 Wonda aims to meet the needs for Enterprise Information Systems and E-Commerce in the construction and banking industries. Wonda aims to deliver a solution suitable for contracting firms. The solution should enable take-up by SMEs, incremental value-added growth (perhaps Incremental Radicalism), mobile computing for location independent access by project managers and quick set-up of virtual enterprises reflecting both the short customer-supplier relationships in the industry and the need of construction firms to constantly re-configure and re-invent themselves. Method: Wonda will develop an open and secure framework for business objects and electronic payment. Business objects can be defined as software components, which encapsulate business rules and procedures and which can run anywhere on the network. They provide secure and sophisticated access to diverse electronic content and software applications. Indeed, just as a building can be described as a unique arrangement of standard products, a building project can be described as a unique arrangement of standard product data. Business Objects give a high level view of product data. They can be assembled into frameworks to support high-level views on industrial projects. The open framework will enable a distributed architecture through CORBA thus facilitating the interoperation of heterogeneous software components as found in legacy systems. The modular security of the framework and its support for electronic payment ensure authenication, confidentiality and non-repudiation as required for the business processes of construction virtual enterprises. Indeed the modular and incremental implemenation of security will be achieved partly through a Business Object architecture. Results will comprise o a pilot in 2 product cycles, o an open & secure framework architecture, o Commotion middleware for enabling business objects on top of Corba, o WeBuild (construction), WeBank (banking) and SILK (security) business objects o OpenDMX component to enable object orientated access to legacy databases.

doi	https://doi.org/10.52842/conf.ecaade.1998.041
summary	As the cost of 3D digitisers drops and PC price performance rises, opportunities for hand - computer co-operation improve. Architectural form may now be experimentally moulded or carved using manual techniques in close association with the computer. At any stage the model can be mechanically digitised and translated to a computer database for explorations that go beyond simple physical manipulation. In the virtual environment, the resulting forms can be rationalised using an ordering geometry or further de-rationalised. This potential for debasing intuitive, sensually haptic and responsive handwork through its translation into numerically cogent formulations is risky business. But it may also bring new and unlikely rewards. This paper considers the implications and aesthetics of negotiations between handcraft and consecutive or synchronous computer digitalisation of intentions. Two situations will be discussed and compared. The first is the nature of computer modelling and its representation per se, and the second is the relevance of using handcraft as a sponsor for computer-based manipulation and morphological experimenting.

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.

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 presents the basic ideas of a computer system for supporting urban design and decisions on land use. We argue, that the high complexity of urban design - inherent in the its large number of interdependent views and aspects - seems to justify a flexible support system capable of reasoning and conceptual modelling. Such a system may be prohibitively resource demanding unless we are able to build it up from smaller and larger modules of different types and functionality and which canbe created basically in an incremental way without a complete plan in advance. Two prototypes concerning urban designs and a small flexible design rule interpreter/handler is presented for free standing buildings.

title	Design concept as a model for modelling design process and its knowledge
source	The Int. Journal of Construction IT 6(2), pp. 87-103
summary	The strategy of decomposing a design problem into subproblems is commonly used in engineering design. One difficulty in applying this strategy to computer-based design systems is the assembly of subproblem solutions to construct a whole solution. Despite its advantages, this design strategy suffers two major problems. First, as constraints are ill defined and implicitly exist among design objects, it is very difficult to articulate and represent design constraints in computable forms. Second, as design subproblems are designated separately in computer-based design systems, the inherent relationships among subproblems are not considered in contriving these subproblems. As a result, recomposing subproblem solutions is hard to do. This paper presents a model for modelling design processes and the knowledge involved. The model is called ‘design concept’, which represents empirical interconnections of design attributes and intraconnections of design subproblems. Topological relations are represented using decomposition trees. The advantages and disadvantages of integratively using decomposition trees and design concepts in facilitating conceptual design are discussed

source	II Seminario Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings / ISBN 978-97190-0-X] Mar del Plata (Argentina) 9-11 september 1998, pp. 342-349
summary	In the modelling process of curve shapes, some conic lines have been privileged to the point that they have become tools in CAD systems: circumferences and ellipses. Others have been ignored to the point of being excluded: parabolas and hyperbolas. Important reasons make this rescue convenient. One of those is that these curves are frequently used in design because of their distinct identification. In theory, modern "splines" and "nurbs" cover the whole range of whatever a designer might want to draw (as far as curve shapes are concerned). However, its structuring capacity cannot be compared to that of conic lines. To have all the conceivable curves and to lack the possibility of organizing them, restricts its morphological potentialities. There is a set of notable curves, among others lemiscates, spirals and Cassinian ovals, that keep waiting for new technologies to give them the possibility of existence. Though these lines have a high aesthetic and graphic value, they are not frequently included in projects. This is not because they are unsuitable, but because there are not simple possibilities of drawing them. We expect graphic computing will fill this empty place, so that these shapes become part of our habitat.

title	Model of Design Parts and its Use to the Design Team

doi	https://doi.org/10.52842/conf.caadria.1998.233
summary	This paper discusses the impact of the choice of representation on the final result in design and construction projects. Representation is an integrated part of the design process used by architects as a communication tool to help them present a concept to their clients and other consultants. The representation choice, in addition, reflects the professional’s perception of the design process and the architectural artefact. Architects’ offices work with a wide range of problems - aesthetic and spatial issues, detailing, choice of materials, and systems design. The multiplicity of representations enriches the understanding of these issues. Today, the model-oriented approach in design is common among both architects and leading software producers for the construction industry. While STEP (Standard for the Exchange of Product Data) aims at developing very comprehensive product models, we examine the possibility of building up a small-scale model responding to the information needs of a design team. In our research work, we view a model of design parts as a suitable carrier of information allowing the designers to store data reflecting their accumulated and refined professional knowledge and experience. Besides, the team of architects can later easily retrieve information needed for future design reuse from the model. To reuse design solutions and learn from previous work is an essential part of the professional culture. The construction industry as a whole has been slow in implementing information technology to improve the work methods. Neither have architects’ offices used the full potential of this technology to structure information and rationalize the design process. The objective of this study is to examine whether information technology makes it possible to organize all the design information in an office archive. The proposed model of design parts relates to national standards and universal models for product data representation and exchange, such as STEP. Today, the construction sector is becoming increasingly aware of the potential of the model-oriented approach both to rationalize the design and construction process and offer designers new options to store, broaden and reuse professional knowledge. We have used the information modelling language EXPRESS to describe our concept.

summary	This paper presents a specification of a Local Housing Strategy Decision Support System (LHS-DSS) (Conceptual and Physical model design). Emphasis throughout the design process is laid on the techniques that provide housing planners with accurate rapid assistance during the preparation process of local housing strategy. Relevant knowledge (descriptive, procedural, reasoning) and data about each step of the process, options for each situation as it arises, and a record of decisions made with underlying reasons are provided to system users. Three main components are identified to shape up the LHS-DSS: the language system for addressing housing problems; knowledge system which is responsible for gathering and accumulating the housing knowledge required; and problem processing system (an inquiry system) which produces suitable and effective recommendations to support the strategy preparation process.
