title	GIS Support for urban planning in wuhan, p.r.china
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary	The shift from a planned economy to a market economy has been a great challenge for the urban planning bureau of Wuhan. This challenge lies partially in finding new land for the rapid urban expansion as well as redeveloping existing urban areas especially inner city areas. The urban planning bureau initiated two projects: the revision of the master plan and the development of an urban renewal plan. In both plans the university assisted in spatial data analysis and the development of a spatial data model to support the inner city redevelopment process.

title	How to support city planning using map interpretation techniques
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary	We suggest and motivate a system to support city traffic planning. Our approach is derived from Case-Based Reasoning (CBR), where former experiences (cases) are stored and made available for reuse. To start with, a collection of examples from books or other sources is stored as hypermedia documents. Retrieval of useful examples is enabled by describing (indexing) the examples in several aspects. While some descriptors have to be attached by users or system administrators, others could be automatically inferred. The vision is, that in the long run cases are derived from GIS plans and the CBR support is an integrated tool in a GIS working environment.

title	A computer simulation model of the TU district of Delft with use of the GIS and VR
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary	One of the big problems for GIS users is a luck of such an visual presentation of data which will easily transform them into a spatial image. Existing systems based on Human-Computer-Interfaces (Ha) have limitations and for this reason it is necessary to discover new explicit way of spatial data presentation and manipulation. Virtual Reality technology with its specificity and characteristics based on spatial displaying and multisensory interactivity, give to VR users a new promising possibility to solve GIS limitations. This research is an exploration of integration of GIS and yR. VR is a kind of production of a simulation of a real world, and GIS-databases contain data that describe this world, therefore a success of combination of both technologies is very probable. This research shows possibilities for creating a virtual GIS world in which is possible to handle, explore, analyse and present spatial data by free navigation through a virtual model. The virtual model of Delft University of Technology's Campus presents Virtual Reality as a new type of 3D interface for GIS and demonstrates some basic GIS functions in virtual environment. It has been created by importing of GIS databases into VR system. Virtual model is based on geometric and attributive data. GIS functionality is enabled by 3D interface objects, that symbolically and semantically represents GIS functions. Their use should initiate intuitive users action. This application combines spatial data, user interface, text, sound, thematic data and virtual hypertext. Virtual model enables the use of quantitative and qualitative information. The results of the research can be implemented to support design strategies ax! decision making in the field of physical and urban planning.

title	Multimedia Training "Designing Randstad"
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary	The project multimedia training "Designing Randstad" (MTDR) is an experimental attempt to introduce multimedia in education at the Faculty of Architecture in Delft. It intends to develope teachware which will learn the students the basics of Geographic Informational Systems (GIS) implementation in land use evaluation appropriate for physical planning purposes. Interaction between students and the system will enable students to learn about GIS, to design a model of the spatial development of Randstad area and to evaluate their own designs, to produce immediate graphic visualisation of the evaluation and to compare it with the evaluations of the fellow students. The project will be applied in the first year curriculum, in the course "Region" of the Department of Urban planning of the Faculty of Architecture, in the first half of the year 1997.

title	Consequences of Interdisciplinary Approaches in the Construction ofKnowledge-Bases
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 character of interdisciplinarity in planning approaches create a new, intriguing, emerging complexity (Funtowitcz and Ravetz, 1994) in problems and in knowledge-structuring of contexts of planning practices. The key-role played by information systems (IS) implicates a re-consideration ofcharacter of knowledge to be used in knowledge-bases. The necessity of considering knowledge domains coming from social, cultural, economical, technical, physical and naturalistic approaches means dealing with different scales of value, with non homogenous parameters. The necessity ofmanaging flexible knowledge rises on the fore as fundamental issue for future information system oriented to supporting decisions. Might information systems be useful in this interdisciplinary approach ? It is necessary to contain in a knowledge-base both quantitative and qualitativeinformation ? Three alternatives are available for a conceptual discussion :the possibility of identify new approaches, in order to develop information systems able in managing new knowledge; the necessity of adding new support systems oriented to manage soft knowledge, to traditionalgeographic information systems (GIS); the possibility of non using support systems coming from a technological vision of problem for nontechnical knowledge (Latouche 1996). The first two paragraphs are due to F. Selicato. The third and the fourth paragraph are due to C. Torre.

title	Route related data of shopping centre visitors and geographical information systems
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary	Pedestrian route information can support different research activities such as the calculation of economic performances of shopping streets, the evaluation of parking policy measures, and the development of pedestrian design standards. These research activities are helpful in planning and designing shopping centres. Pedestrians' routes are used to measure walking distances, calculate other route related data, and estimate pedestrians' densities. To use route related data efficiently, it is necessary to capture the observed routes of pedestrians in some kind of computer system. Geographical Information Systems (GIS) might offer an opportunity to deal with route related data because they can handle spatial and non-spatial data for example of line segments. However, very few GIS offer tools to enter, store, analyze and display route related data. In the new version of TransCAD a special Route System module is implemented to handle routes. The route system stores the routes, the different links routes are made up, and the possible stops on the route in separate tables that can be analyzed and displayed in a map. This paper describes the structure and the contents of pedestrians' route information as it can be used in various research projects. From these research projects some general requirements to handle route related, are extracted. Special attention is paid to the way TransCAD deals with routes. A parking research conducted in the main shopping centre of Veldhoven is used to describe and illustrate the possibilities of route related data of pedestrians, and evaluate the possibilities TransCAD offers to deal with this kind of data.

title	Generic Representations and the Generic Grid: Knowledge Interface, Organisation and Support of the (early) Design Process
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary	Computer Aided Design requires the implementation of architectural issues in order to support the architectural design process. These issues consist of elements, knowledge structures, and design processes that are typical for architectural design. The paper introduces two concepts that aim to define and model some of such architectural issues: building types and design processes. The first concept, the Generic grid, will be shown to structure the description of designs, provide a form-based hierarchical decomposition of design elements, and to provide conditions to accommodate concurrent design processes. The second concept, the Generic representation, models generic and typological knowledge of building types through the use of graphic representations with specific knowledge contents. The paper discusses both concepts and will show the potential of implementing Generic representations on the basis of the Generic grid in CAAD systems.

title	An optimization method of the facility location by genetic algorithm
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary	In planning of community-facilities, it is important to decide the facility location to provide the effective service for residents. The behavior of residents using the facility and the evaluation methods of the location have been studied. But, finding the optimum location is very hard in actual planning because the volume of calculation depends on the number of feasible locating points of facilities. To conquer the difficulty of searching the optimum location, we propose an optimization method using Genetic Algorithm. An alternative of location is expressed by a chromosome. Each chromosome consists of genes, and each gene expresses a located zone of the facility. We gave definitions of genetic procedures; crossing-over, mutation and selection. Alternatives of the facility location are generated by these genetic procedures like as life evolution. For each alternative, the behaviors of users are estimated by a spatial-interaction model, and the facilities that residents in each place choose are determined. The effectiveness of the location is measured by a total sum of distances between the facility and the user. After the confirmation of the effectiveness of our method by applying on ideal example problems, we applied it on the actual problem in Japanese town. By this method we could find the optimum location in about one-third time and effort as compared with the ordinal method.

title	A knowledge-based model for developing location strategies in a DSS for retail planning
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary	Most DSS for retail planning are based on impact assessment models to support the evaluation of plan scenario's. This paper introduces a complementary knowledge-based model to support also the earlier stage of formulating plan scenario's. An analysis of the retail planning problem reveals the main lines of the strategies adopted by most Dutch planners and retailers to achieve their goals. A basic strategy that seems to be appropriate in most problem contexts is formulated in the form of a set of decision tables. Each decision table or system of decision tables specifies for a problem area decision rules to identify and analyse problems and to formulate possible actions. The model is implemented in a DSS where it is used in combination with quantitative impact assessment models. A case study in the area of daily good facilities demonstrates the approach. The major conclusion is that the knowledge-based approach and in particular the decision table technique provides interesting possibilities to implement planning task structures in a DSS environment.

title	Semi-manual design support for increasing railwaystation catchment & sustainable traffic routing
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary	The shape ('configuration'), location and direction of the pattern of potential trips by foot or bicycle can help decision makers and designers:- the shape of such a pattern informs about the potential size of a traffic calming area(such as 30Km-zoning),- the location of such a pattern refers to the user-groups and specific destinations that a urban network should bring in safe reach for dictated groups,- the direction of such a pattern, together with shape and location, points to the best routing to raise the Sustainable Traffic Modal Split or to improve the reach of destinations like a railway-station.The patters can be generated from zip-code's of user-groups with obvious and daily destinations (school-children, rail-passengers). The next step confronts the theoretical pattern with the layout of streets and the traffic flow, mapping or listing (potential) confrontations between cars and the non-motorised modes, a basis for economical investment in traffic-safety.A design can 'model' the analysed pattern(s) to a economic, direct and safe base (cycle or pedestrian) network. In co-operation, the Dutch the traffic consultant "Verkeersadviesbureau Diepens & Okkema" in Delft, The Netherlands and the Faculty of Architecture, Delft University of Technology, in Delft, The Netherlands, develloped the semi-manual design & decision support system "STAR-Analysis"

title	A Conceptual Model for Concurrent Engineering in Building Design according to Domain Theory
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary	Concurrent engineering is a design strategy in which various designers participate in a co-ordinated parallel process. In this process series of functions are simultaneously integrated into a common form. Processes of this type ask for the identification, definition and specification of relatively independent design fields. They also ask for specific design knowledge designers should master in order to participate in these processes. The paper presents a conceptual model of co-ordinated parallel design processes in which architectural space is simultaneously defined in the intersection of three systems: a morphological or level-bound system, a functional or domain-bound system and a procedural or phase-bound system. Design strategies for concurrent engineering are concerned with process design, a design task which is comparable to the design of objects. For successfully accomplishing this task, knowledge is needed of the structural properties of objects and systems; more specifically of the morphological, functional and procedural levels which condition the design fields from which these objects emerge, of the series of generic forms which condition their appearance and of the typological knowledge which conditions their coherence in the overall process.

title	Impact-Analysis of Urban Design Realtime impact-analysis models for urban designers
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary	The past five years Prof Dr Jr T.M. de Jong, professor in environmental planning and sustainability at the Technical University of Delft, has developed a theoretical foundation for the analysis of urban design on the ecological, technical, economical, cultural and political impacts of morphologic interventions on different levels of scale. From september 1994 Jr AJ. Boelen (Urban Design Scientist and Knowledge Engineer) started a research project at the same university to further explore the possibilities of these theories and to develop impact evaluation models for urban design and development with the theoretical work of De Jong as a starting point. The paper discusses the development of a design and decision support system based on these theories. For the development of this system, techniques like object-orientation, genetic algorithms and knowledge engineering are used. The user interface, the relation between the real world, paper maps and virtual maps and the presentation of design-interventions and impacts caused by the interventions are important issues. The development-process is an interactive step by step process. It consists of the making of a prototype of the system, testing the theory and hypothe-sisses the system is based on, by applying tests end adjusting the theory and hypothesisses where needed. Eventually the system must be able to act as an integrator of many different models already developed or still to be developed. The structure of the system will allow easy future expansion and adjustment to changing insights. The logic used to develop the basic theory on which this system is founded makes it possible to even introduce and maintain rather subjective aspects like quality or appraisal as impacts that can be evaluated. In a previously developed system "Momentum" this was proved to work effectively for the national level. In this project we will - amongst other things - try to prove the effectiveness of impact-evaluation for other levels of scale.

title	Prototyping of Designs in Virtual Reality
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary	Conventional CAD systems have not yet proven their ability to provide support for activities which characterise the early conceptual phase of design. We propose to refer to this set of capabilities of the human designer in conventional design as, design prototyping. We define the theoretical limitations of current CAD systems for supporting design prototyping, and postulate the potential of functionally dedicated, task related, CAD modules in Virtual Reality as a means to provide a unique form of a knowledge-based, visual design support environment for design prototyping support. We are currently engaged in a research program in which we explore CAD as a medium to support early conceptual design through rapid prototyping of architectural form. Furthermore we are exploring Virtual Reality as a potential design prototyping environment in which prototypes of designs can be constructed, communicated and visually evaluated at a high level of verisimilitude. In the first phase we have built the prototype system VIDE. This system has been used for extensive internal evaluation. In the ongoing second phase we are constructing an empirical research to observe designers at work on design prototyping in the Virtual Reality environment.

title	Morphogenetic Designing in Architecture resolving controversies in and between design, research and development
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary	There is a dearth of software able to support the working styles of all types of designers and design scholars, spanning the whole spectrum of hermeneutical and empirical traditions. The development of morphogenetic designing in architecture opens new possibilities to bridge the gap between the different traditions. It can support the birth of forms evolving one from the other with the help of local and global rules in genetic algorithms and neural networks which translate the wishes of the designer. It can also support the communication about these forms and the testing of their adequacy. On the other hand the design process which is reflected in the sequence of form generating acts can be studied by design researchers better than by protocols alone.

title	Criteria for the Selection of Conceptual Modelling Languages for Knowledge Based Systems
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary	In recent years knowledge is increasingly recognised as a critical production factor for organisations. Performance of activities such as designing, diagnosing, advising and decision making, depend on the availability and accessibility of knowledge. However, the increasing volume and complexity of knowledge endangers its availability and accessibility. By their knowledge processing competence, knowledge based systems containing a structured and explicit representation of knowledge, are expected to solve this problem. In the realisation of a knowledge based system, the phase in which a knowledge model is reconstructed through a conceptual language, is essential. Because the knowledge model has to be an adequate reflection of real-world knowledge, the conceptual language should not only offer sufficient expressiveness for unambiguous knowledge representation, but also provide facilities to validate knowledge on correctness, completeness and consistency. Furthermore, the language should supply facilities to be processed by a computer. This paper discusses fundamental criteria to select a conceptual language for modelling the knowledge of a knowledge based system. It substantiates the claim that the selection depends on the nature of the knowledge in the application domain. By analysing the nature of knowledge using the theory of functional object-types, a framework to compare, evaluate and select a conceptual language is presented. To illustrate the selection process, the paper describes the choice of a conceptual language of a knowledge based system for checking office buildings on fire-safety demands. In this application domain, the language formed by decision tables has been selected to develop the conceptual model. The paper provides an in-depth motivation why decision tables form the best language to model the knowledge in this case.

title	The TIE-system, a KBS for the Evaluation of Thermal Indoor office Environments
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary	A Knowledge-Based System [KBS] for the evaluation of Thermal Indoor office Environments [TIE] (in the Netherlands) was the product of a one-year project, undertaken by researchers of the Physical Aspects of the Built Environment group [FAGO] in cooperation with the Knowledge-Based System Section of the TNO-Building & Construction research Institute in Delft. The objective of the project was to develop a KBS capable of evaluating thermal indoor environments of existing or proposed office buildings designs. The approach used in this study was based on a traditional method of predicting thermal sensation by calculating Fanger's 'Predicted Mean Vote' [PMV]. PMV is influenced by four environmental parameters of a room: air temperature, radiant temperature, air velocity and relative humidity, and by two personal parameters of the employees: metabolic rate and clothing insulation. The knowledge required to determine these six parameters was placed in KBS-databases and tables using a KBS-building tool called Advanced Knowledge Transfer System [AKTS]. By questioning the user, the TIE-system is capable of determining the PMV for a particular office room. The system also provides conclusions and advice on improving the thermal comfort. The TIE-system was a pilot-study for the long-term Building Evaluation research project, being undertaken at FAGO, that examines in all aspects of office building performance, and in which KBS may play a major pole.

title	CAD Systems for early design phases or CAD systems for designers' early phases
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary	Most of the problems, related with the use of CAD systems are the results of some general principles; the philosophy that, those systems are based on. Therefore, mainly the relation between these principles and early design phase performance of CAD systems and designers are discussed in this paper. The circumstances of novice CAD user architects in Turkey is considered first. In formation of the research, the knowledge gained during my personal experience based on real cases from the university (education, research) and practice (design, consulting) is used. Beside this the results of a survey including a serious of interviews projecting the opinions of the architects is used. Vendors of commonly used CAD systems were interviewed. In this manner to answer the main question about the relation of "CAD" and "early design phase" the answers of some following questions and facts were investigated: What means CAD for architects? What are the main purposes of using CAD? Are CAD systems sufficient to be used in early design phases in terms of either hardware and / or software, or should we say thinkware?. The advantages and disadvantages of using CAD. The target user fact and its consequences (the difference between general purpose systems and the sophisticated architectural systems). Should we adapt to computerized way of thinking? Is 3D a basic feature? What are the education related problems of CAD? Is software integration problem solved? Modularity concept for CAD systems. What is the minimum time, and the budget required for a start? The illegal software use problem Complaints, demands, needs and thanks of architects? Simply, what do architects expect from CAD during design process and particularly in early phases (both of design and designer)? Do CAD systems match this?

title	A Design & Decision Support System Proposal for Housing
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary	The subject of this study is to develop an information management system integrating all the related specialists and sources of information virtually from all related fields in building sector (housing) of Turkey; including design, production, construction, marketing, research. The application field has been chosen as housing for having a contribution to the existing housing problem. Although the subject of architecture is one : "the building", the specialists taking place during the lifetime of a building (from design, to destruction) are numerous. Moreover the links between practitioners, academicians, industry are missing Conventional methods, technology are expensive, time consuming. and insufficient to establish and maintain a healthy coordination between these contributors (mainly the design team and all the other related persons, institutions etc.). This has a strong negative effect on the concepts of "wholeness " and "integrity". The result is a built environment which is lacking significant qualities, while the money has been spent is even much more than required for a proper result. This means the loss of a considerable amount of resources. Especially in a country, which has to build thousands of houses each year, for low income groups, the efficient use of the limited sources becomes more essential. Though the potential user range of the system may include constructors, contractors, building element / material producers and retailers, surveyors, institutions, universities, the main user is aimed to be the architect. The system is aimed to support designers to deal with "complexity" without neglecting the concept of "wholeness". Within the study, the problems which became a stimulus for the development of this system will be investigated. The philosophical base, structure and the possible advantages of the proposal will be discussed.

title	Conjoint measurement in virtual environment: a framework
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary	Conjoint analysis (also called stated preference analysis) involves the use of designed hypothetical choice situations to measure individuals' preferences and predict their choice in new situations. Conjoint experiments involve the design and analysis of hypothetical decision tasks. Alternatives are described by their main features, called attributes. Multiple hypothetical alternatives (product profiles) are generated and presented to respondents, who are requested to express their degree of preference for these profiles. Conjoint experiments have become a popular tool to model individual preferences and decision-making in a variety of research areas. Most studies of conjoint analysis have involved a verbal description of product profiles, although some studies have used a pictorial presentation of product profiles. This paper describes a framework for a conjoint analysis system in a virtual environment. Product profiles are generated in a virtual environment and respondents are requested to choose in that virtual environment the product profile they prefer. Advantages of a virtual environment in this area of research include 3D presentation, improved experience and the possibility to include measurable attributes such as time and sound. This framework is a first attempt to explore the possibilities of virtual reality systems in conjoint analysis.
