This paper reviews the potential for collaborative groupwork creation and maintenance of such models and suggests an approach to data entry, data management and generation of appropriate levels of detail models from a Geographic Information System (GIS). Staff at the University of the West of England (UWE) modelled a large area of Bristol to demonstrate millennium landmark proposals. It became swiftly apparent that continued amendment of the model to keep it an accurate reflection of changes on the ground was a major data management problem. Piecing in new CAAD models received from Architectural Practices to visualise them in context as part of the planning negotiation process has often taken staff several days of work for each instance. The model is so complex and proprietary that Bristol City operates a specialist visualisation bureau service. UWE later modelled the environs of the Tower of London to support bids for funding and to provide the context for judging the visual impact of iterative design development. Further research continued to develop more effective approaches to. Data conversion and amalgamation from all the diverse sources was the major impediment to effective group working to create the models. It became apparent that a GIS would assist retrieving all the appropriate data that described the part of the model under creation. It was possible to predict that management of many historic part models stepping back through time, allowing for different expert interpretations to co-exist would be in itself a major task requiring a spatial database/GIS. UWE started afresh from the original source data, to explore the collaborative use of GIS and Virtual Reality Modelling Language (VRML) to integrate models and interventions from various sources and to generate an overall navigable interactive whole. Current exploration of the combination of event driven behaviours and Structured Query Language is seeking to define how appropriately to modify objects in the VRML model on demand. This is beginning to realise the potential for use of this process for: asynchronous group modelling on the lines of a collaborative virtual design studio; historic building maintenance management; visitor management; interpretation of historic sites to visitors and public planning information.}, subject = {Raumordnung}, language = {en} } @phdthesis{Schneider2000, author = {Schneider, Ulrich}, title = {Standardisierung der Kommunikation als Integrationsansatz f{\"u}r das Bauwesen}, doi = {10.25643/bauhaus-universitaet.72}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20040311-751}, school = {Bauhaus-Universit{\"a}t Weimar}, year = {2000}, abstract = {In dieser Arbeit wird eine neue Methode f{\"u}r die Integration von Informationen in digitalen Planungsunterlagen erarbeitet.

This trend is even more evident in high technology industries, such as the computer industry and the chemical industry. Fast changing markets, such as the computer industry, force companies to have to build new facilities quickly. To make a statement about construction progress, the status of a building has to be determined and monitored over a period of time. Depicting the construction progress in a diagram over time, statements can be made about the anticipated completion of the project and delays and problems in certain areas. Having this information, measures can be taken to efficiently >catch up< on the schedule of the project. New technologies, such as wearable computers, speech recognition, touch screens and wireless networks could help to move electronic data processing to the construction site. Progress monitoring could very much take advantage of this move, as several intermediate steps of processing progress data can be made unnecessary. The processing of progress data could be entirely done by computers, which means that data for supporting decisions can be made available at the moment the construction progress is measured. This paper describes a project, that investigates how these new technologies can be linked to create a system that enhances the efficiency of progress monitoring. During the project a first prototype of a progress monitoring system was developed that allows construction companies and site supervisors to measure construction progress on site using wearable computers that are speech controlled and connected to a central database via a wireless network.}, subject = {Bauablauf}, language = {en} } @inproceedings{Hommel2000, author = {Hommel, Angela}, title = {The Theory of Difference Potentials in the Three-Dimensional Case}, doi = {10.25643/bauhaus-universitaet.595}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20111215-5956}, year = {2000}, abstract = {The method of difference potentials can be used to solve discrete elliptic boundary value problems, where all derivatives are approximated by finite differences. Considering the classical potential theory, an integral equation on the boundary will be investigated, which is solved approximately by the help of a quadrature formula. The advantage of the discrete method consists in the establishment of a linear equation system on the boundary, which can be immediately solved on the computer. The described method of difference potentials is based on the discrete Laplace equation in the three-dimensional case. In the first step the integral representation of the discrete fundamental solution is presented and the convergence behaviour with respect to the continuous fundamental solution is discussed. Because the method can be used to solve boundary value problems in interior as well as in exterior domains, it is necessary to explain some geometrical aspects in relation with the discrete domain and the double-layer boundary. A discrete analogue of the integral representation for functions in will be presented. The main result consists in splitting the difference potential on the boundary into a discrete single- and double-layer potential, respectively. The discrete potentials are used to establish and solve a linear equation system on the boundary. The actual form of this equation systems and the conditions for solvability are presented for Dirichlet and Neumann problems in interior as well as in exterior domains}, subject = {Randelemente-Methode}, language = {en} } @inproceedings{WainainaRichterKirchheim2000, author = {Wainaina, Simon and Richter, Matthias and Kirchheim, Alfred}, title = {The Use of Activity Chain Models to Analyse Stochastic Travel Demand}, doi = {10.25643/bauhaus-universitaet.615}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20111215-6157}, year = {2000}, abstract = {For analysis and planing of transport networks detailed information concerning travel sequences is required. The paper examines an activity chain model to determine stochastic travel demand which individual generates in order to participate in activity or sequence of activities over the day. The transition from one activity to another depends on the activity participation decision, which is made sequentially and is constrained in space and time. Activity chains derived from travel survey data are used as a base to develop a more realistic model than conventional discrete trip models. Probabilistic concepts and statistical procedures are used to estimate characteristics of travel demand such as the number of daily out-of-home activities and transition probability from one activity to another participated by homogeneous behavioural groups.
