Programs like Maple, Matlab, MathCAD and Mathematica are popular in this field. To the knowledge of the authors, the widest application functionality offers the program Maple. Its advantages are, e.g. the alternatively symbolic or numerical solution of differential equation systems, the easy handling of parameter studies, the immediate visualization of results, the definition of macros for selected calculation steps and their export in other computer languages and, not least, the automatically generated, very clear documentation of the matehematical calculus.}, subject = {Bautechnik}, language = {en} } @article{ZavadskasKaklauskas2004, author = {Zavadskas, Edmundas Kazimieras and Kaklauskas, Arturas}, title = {Civil Engineering Decision Support Systems in Lithuania}, doi = {10.25643/bauhaus-universitaet.257}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20111215-2579}, year = {2004}, abstract = {Civil engineering decision support systems (construction, building life cycle, refurbishment, total quality management, innovation, etc.) created in Lithuania are described in this paper. The above decision support systems comprise of the following constituent parts: data (database and its management system), models (model base and its management system) and a user interface. Presentation of information in databases may be in conceptual (digital, textual, graphical, photographic, video) and quantitative forms. Quantitative information presented involves criteria systems and subsystems, units of measurement, values and initial weight fully defining the variants provided. The databases were developed providing a multiple criteria analysis of alternatives from economical, infrastructure, technical, technological, qualitative, legislative, social and other perspectives. This information is provided in a user-oriented way. Since the analysis of alternatives is usually performed by taking into account economical, infrastructure, technical, technological, qualitative and other factors, a model-base include models which enable a decision maker to carry out a comprehensive analysis of the variants available and make a proper choice. These systems, related questions and practical case study were analysed the paper.}, subject = {Wissensmanagement}, language = {en} } @inproceedings{Hartmann2004, author = {Hartmann, Ulrich C.}, title = {Collaboration in AEC Design : Web-enabling Applications using Peer-to-Peer Office Communicator}, doi = {10.25643/bauhaus-universitaet.138}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20111215-1386}, year = {2004}, abstract = {A market analysis conducted by Gartner Dataquest in August 2001 has shown the typical characteristics of the AEC design process. High volatility in membership of AEC design groups and members dispersed over several external offices is the common collaboration scenario. Membership is most times short lived, compared to the overall duration of the process. A technical solution has to take that into account by making joining and leaving a collaborative work group very easy. The modelling of roles of collaboration between group members must be based on a commonly understood principle like the publisher / subscriber model, where the individual that is responsible for the distribution of vital information is clear. Security issues and trust in the confidentiality of the system is a central concern for the acceptance of the system. Therefore, keeping the subset of data that will be published under the absolute control of the publisher is a must. This is not the case with server-based scenarios, sometimes even due to psychological reasons. A loosely bound Peer-to-Peer network offers advantages over a server-based solution, because of less administrative overhead and simple installation procedures. In a peer-to-peer environment, a publish/subscribe role model can be more easily implemented. The publish/subscribe model matches the way AEC processes are modelled in real world scenarios today, where legal proof of information exchange between external offices is of high importance. Workflow management systems for small to midsize companies of the AEC industry may adopt the peer-to-peer approach to collaboration in the future. Further investigations are being made on the research level (WINDS) by integrating the viewer and redlining application Collaborate! into a collaborative environment.}, subject = {Ingenieurbau}, language = {en} } @inproceedings{HassanShelbournCarter2004, author = {Hassan, Tarek and Shelbourn, Mark and Carter, Chris}, title = {Collaboration in Construction: Legal and Contractual Issues in ICT Applications}, doi = {10.25643/bauhaus-universitaet.2007}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20111215-2005}, year = {2004}, abstract = {The construction industry is a project-based business bringing together many different organisations to complete a desired goal. The strategic use of Information and Communication Technologies (ICT) has enabled this goal to be completed more effectively. Two issues require addressing, the technology itself and the implementation factors of the technology. Such implementation factors should consider, among other factors, the legal and contractual issues associated with the use of ICT, training requirements and its effects on the organisational culture. To date the legal and contractual issues have not been extensively covered, and it is recognised that the technologies have not been properly covered by any recognised legal and contractual practices. This in turn is threatening to inhibit the growth and prosperity of the use of the technology on construction projects. This paper discusses these legal and contractual issues and describes methods and tools that can be used to enable the growth of technology to be used in a legal and contractually valid environment.}, subject = {Forschung}, language = {en} } @inproceedings{SoibelmanO'BrienElvin2004, author = {Soibelman, Lucio and O'Brien, William and Elvin, George}, title = {Collaborative Design Processes: A Class on Concurrent Collaboration in Multidisciplinary Design}, doi = {10.25643/bauhaus-universitaet.194}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20111215-1948}, year = {2004}, abstract = {The rise of concurrent engineering in construction demands early team formation and constant communication throughout the project life cycle, but educational models in architecture, engineering and construction have been slow to adjust to this shift in project organization. Most students in these fields spend the majority of their college years working on individual projects that do not build teamwork or communication skills. Collaborative Design Processes (CDP) is a capstone design course where students from the University of Illinois at Urbana-Champaign and the University of Florida learn methods of collaborative design enhanced by the use of information technology. Students work in multidisciplinary teams to collaborate from remote locations via the Internet on the design of a facility. An innovation of this course compared to previous efforts is that students also develop process designs for the integration of technology into the work of multidisciplinary design teams. The course thus combines both active and reflective learning about collaborative design and methods. The course is designed to provide students the experience, tools, and methods needed to improve design processes and better integrate the use of technology into AEC industry work practices. This paper describes the goals, outcomes and significance of this new, interdisciplinary course for distributed AEC education. Differences from existing efforts and lessons learned to promote collaborative practices are discussed. Principal conclusions are that the course presents effective pedagogy to promote collaborative design methods, but faces challenges in both technology and in traditional intra-disciplinary training of students.}, subject = {Hochschulbildung}, language = {en} } @inproceedings{MilesJoitaBurnap2004, author = {Miles, John and Joita, Liviu and Burnap, Peter}, title = {Collaborative Engineering: Virtual Teams in a Grid Environment Supporting Consortia in the Construction Industry}, doi = {10.25643/bauhaus-universitaet.136}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20111215-1362}, year = {2004}, abstract = {In the AEC (Architecture / Engineering / Construction) industry a number of individuals and organisations collaborate and work jointly on a construction project.
