  abstract  = {In Zeiten volatiler Immobilienm{\"a}rkte und einer hohen Wettbewerbsintensit{\"a}t sind leistungsf{\"a}hige Systeme der Analyse und Entscheidungsunterst{\"u}tzung unverzichtbar. Entscheidungen zu Investitionsstrategien und Einzelinvestitionen basieren zumeist auf mehreren entscheidungsrelevanten Kriterien. Unterschiedliche immobilienwirtschaftliche Entscheidungsalternativen k{\"o}nnen dabei durchaus Kriterienauspr{\"a}gungen aufweisen, die eine bestimmte Alternative nicht als stets besser bzw. stets schlechter ausweisen. Klassische finanzwirtschaftliche Modelle oder verbreitete qualitative Verfahren wie das Scoring k{\"o}nnen die gegebene Komplexit{\"a}t meist nicht angemessen ber{\"u}cksichtigen. Eine Weiterentwicklung immobilienwirtschaftlicher Entscheidungsmodelle ist durch die {\"U}bertragung und Spezifizierung multikriterieller Verfahren der Entscheidungsunterst{\"u}tzung m{\"o}glich. Speziell die Untergruppe des Outranking besch{\"a}ftigt sich mit der schrittweisen Strukturierung, Ordnung und Priorisierung von komplexen Auswahlalternativen. Als spezifische immobilienwirtschaftliche Fragestellung dient hier die Auswahl und Priorisierung von Zielm{\"a}rkten im taktischen Portfoliomanagement eines institutionellen Immobilienportfoliosmit internationaler Ausrichtung. Die Formalisierung des Entscheidungsproblems „Priorisierung von Zielm{\"a}rkten" erfolgt mit dem ELECTRE-Verfahren.},

  abstract  = {Die Charakteristiken von Großprojekten werden bei internationaler Baut{\"a}tigkeit vor allem durch das erh{\"o}hte Risiko und die Komplexit{\"a}t infolge l{\"a}nderspezifischer Rahmenbedingungen erweitert. Aufgrund des anwachsenden Konkurrenzkampfes international t{\"a}tiger Bauunternehmen, m{\"u}ssen die Gewinnmargen jedoch kontinuierlich verringert werden, w{\"a}hrend Reaktionsf{\"a}higkeit, Spezialisierung und Flexibilit{\"a}t vorausgesetzt wird. Daher gewinnt das Risikomanagement und die bewusste Entscheidungsfindung im Umgang mit Risiken verst{\"a}rkt an Bedeutung. Die zur Verf{\"u}gung stehenden Risikoanalysetechniken untersuchen zumeist Teilbereiche und stellen in der Regel hohe Anforderungen an den Dateninput. Die Daten k{\"o}nnen nur aus vorangegangenen Projekten oder aus Expertenurteilen abgeleitet werden. Diese Tatsache steht im Widerspruch zur Einmaligkeit von Bauprojekten und zur schwierigen Beschaffung realer Daten und Einsch{\"a}tzungen von Praxispartnern. Folglich leitet sich der Bedarf nach einer Entscheidungsmethode ab, die den Risikoumfang in seiner Gesamtheit erfassen kann und losgel{\"o}st von quantitativen Daten eine Entscheidungsunterst{\"u}tzung herbeif{\"u}hrt. Aus diesem Grund wurde in der vorliegenden Diplomarbeit am Beispiel von identifizierten Risiken f{\"u}r Wasserbauprojekte in Indien ein multikriterielles Entscheidungsmodell entwickelt, dem die Arbeitsweise des Analytic Hierarchy Process (AHP) zugrunde liegt und dessen Umsetzung in Excel 2000 erfolgte. Das Modell strukturiert die Problemsituation anhand einer Risikohierarchie, dient der systematischen Risikobewertung zur Veranschaulichung der relativen Bedeutungen innerhalb des Gesamtrisikoumfangs, beinhaltet ein risikobezogenes Zielsystem zur Bewertung von Risikobehandlungsalternativen und erm{\"o}glicht die selbstst{\"a}ndige Wahl der Risikobehandlung. Infolge der prozentualen Anteile jeder Risikobehandlung am Gesamtrisikoumfang k{\"o}nnen Projektstrategien und weitere Erfolgsfaktoren abgeleitet werden.},

  abstract  = {The research reported in this article was conducted to mainly explore the two common numeric prediction techniques, the model tree and the regression tree, when used in conjunction with bagging as a wrapper method. Bagging is used to improve the prediction accuracy of these two algorithms, and results are compared with the ones obtained earlier by the k-nearest neighbor (KNN) algorithm. From the conducted experiments, both the bagged regression tree and bagged model tree produce better results than not only their corresponding regression tree and model tree alone, but also the KNN with optimal value of k equal to 7. In addition, the bagged model tree yields the lowest prediction errors and a highest correlation coefficient of 0.81. It is demonstrated that it is feasible to use the bagged model tree for engineering applications in prediction problems such as estimating the remaining service life of bridge decks.},

  abstract  = {This article discusses how the failures of construction projects could be prevented. The focus is on using IT tools in communication. The article is based on the findings of the PROLABproject. The project seeks to find solutions for how the information can effectively be used in project management, specially in construction projects, what kind of procedures help the management of the knowledge and how the obstacles for efficient ways of administrating the information can be removed. These obstacles can be either related to use of new technology or to organization culture. The paper discusses e-mail as a medium of communication with the media richness framework (Fulk \& Boyd 1991) based on the interviews done with the participants of construction projects. We found out that the emails were used in both rich way and not so rich way. Obstacles of rich use of IT communication were partly technical and partly psychological. Technology acceptance model (TAM) is used to study the actual use of emails in communication. Obstacles of the use of emails were mostly individual differences like the skills to use the system or external variables like they did not have proper software to open the attachments. Also people talked about information overload. Emails often push too much information. Keywords: IT tools, Communication, Knowledge management, Construction},

  abstract  = {This paper reports on the latest results in the development of a new approach for simulating the thermal behavior of buildings that overcomes the limitations of conventional heat-transfer simulation methods such as FDM and FEM. The proposed technique uses a coarse-grain approach to model development whereby each element represents a complete building component such as a wall, internal space, or floor. The thermal behavior of each coarse-grain element is captured using empirical modeling techniques such as artificial neural networks (ANNs). The main advantages of the approach compared to conventional simulation methods are: (a) simplified model construction for the end-user; (b) simplified model reconfiguration; (c) significantly faster simulation runs (orders of magnitude faster for two and three-dimensional models); and (d) potentially more accurate results. The paper demonstrates the viability of the approach through a number of experiments with a model of a composite wall. The approach is shown to be able to sustain highly accurate longterm simulation runs, if the coarse-grain modeling elements are implemented as ANNs. In contrast, an implementation of the coarse-grain elements using a linear model is shown to function inaccurately and erratically. The paper concludes with an identification of on-going work and future areas for development of the technique.},

  abstract  = {A/E/C Team members, while collaborating on building projects, rely on past experiences and content through the use of project design archives (whether in paper or digital format). This leads to underutilization of potential knowledge, as decision-making of data, information, and knowledge reuse is limited by access to these archives, due to sheer size and inconvenient presentation. This paper presents an integrated solution that leverages two technologies CoMem (Corporate Memory) and iRoom (interactive Room) developed at Stanford. This addresses critical limitations, i.e., content, context, visualization and interactivity, constraining the process of collaborative exploration towards knowledge reuse and decision-making.},

  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.},

  abstract  = {This paper describes a research project that addresses the difficulties in dealing with regulatory documents such as national and regional codes. These documents tend to be voluminous, heavily cross-referenced, possibly ambiguous and even conflicting at times. There are often multiple documents that need to be consulted and satisfied; however it is a difficult task to locate all of the relevant provisions. In addition, sections dealing with the same or similar conceptual ideas sometimes lay down conflicting requirements. We propose a framework for regulation representation, analysis and comparison with emphasis on the extraction of similarities between provisions. We focus on accessibility regulations, whose intent is to provide the same or equivalent access to a building and its facilities for disabled persons. An XML regulatory repository is developed to extract structural as well as non-structural features from government regulations to help user understanding and computational analysis. A similarity analysis is performed between different sources of regulations. In order to achieve a better comparison between provisions, we employ a combination of feature matching and structural analysis. Results are shown on comparisons between American and European codes, as well as on the domain of electronic-rulemaking.},

It presents the experience of two high-performance typical but extreme AEC teamwork cases adopting and adapting to collaboration technologies and how these technologies in practice impact their work processes. The findings illustrate the importance of collaboration technologies in cross-disciplinary, global teamwork. Observations indicate that high performance teams that use the collaboration technologies effectively exhibit collaboration readiness at an early stage and manage to define a "third way" to meet the demands of the cross-disciplinary, multi cultural and geographically distributed AEC workspace. The observations and implications represent the blueprint for yearly innovations and improvements to the design of the AEC Global Teamwork program.},
