Den Gegenstand der Dissertation bilden die Konzeption und die exemplarische Realisierung eines verknüpfungsbasierten Bauwerksmodellierungsansatzes zur Schaffung einer integrierenden Arbeits- und Planungsumgebung für den Lebenszyklus von Bauwerken. Die Basis der Integration bildet ein deklarativ ausgerichteter Bauwerksmodellverbund bestehend aus abstrahierten, domänenspezifischen Partialmodellen. Auf Grund der de facto existierenden Dynamik im Bauwerkslebenszyklus werden sowohl der Bauwerksmodellverbund als auch die einzelnen Partialmodelle dynamisch modifizierbar konzipiert und auf Basis spezieller Modellverwaltungssysteme technisch realisiert. Die Verständigung innerhalb der vorgeschlagenen Gesamtbauwerksmodellarchitektur basiert auf anwenderspezifisch zu erstellenden Verknüpfungen zwischen den Partialmodellen und wird im Sinne einer hybriden Modellarchitektur durch eine zentrale, die Verknüpfungen verwaltende Komponente koordiniert. Zur Verwaltung und Abarbeitung der Verknüpfungen wird der Einsatz von Softwareagenten im Rahmen eines Multiagentensystems vorgeschlagen und diskutiert.
The processes in the life cycle of buildings are characterised by highly distinct teamwork. The integration of all the distributed working participants, by providing an environment, which especially supports the communication and collaboration between the actors, is a fundamental step to improve the efficiency of the involved processes and to reduce the total costs. In this article, a link based modelling approach and its “intelligent” link management is introduced (1). This approach realises an integration environment based on a special building model that acts as a decision support system. The link-based modelling is characterised by the definition and specialisation of links between partial models. These intelligent managed links enable a very flexible and task specific data access and exchange between all the different views and partial models of the participants.
Information science researchers and developers have spent many years addressing the problem of retrieving the exact information needed and using it for analysis purposes. In informationseeking dialogues, the user, i.e. construction project manager or supplier, often asks questions about specific aspects of the tasks they want to perform. But most of the time it is difficult for the software systems to unambiguously understand their overall intentions. The existence of information tunnels (Tannenbaum 2002) aggravates this phenomenon. This study includes a detailed case study of the material management process in the construction industry. Based on this case study, the structure of a formal user model for information retrieval in construction management is proposed. This prototype user model will be incorporated into the system design for construction information management and retrieval. This information retrieval system is a user-centered product based on the development of a user configurable visitor mechanism for managing and retrieving project information without worrying too much about the underlying data structure of the database system. An executable UML model combined with OODB is used to reduce the ambiguity in the user's intentions and to achieve user satisfaction.
