Close cooperation of engineers in different fields is the basis of high product quality, short development periods and a minimum of investment costs. For each building the engineers have to create a new fire engineering model. The consistent realization of the fire engineering model in all details has high demands on communication, collaboration and building models. Thereby, to preserve the related design models consistent to each other and compatible with the rules of fire engineering is a complex task. In addition, regulations and guidelines vary according to the building location, so the knowledge base must be integrated dynamically into the planning process. This contribution covers the integration of engineers and design models into a cooperation network on the basis of mobile agents. The distributed models of architectural design, structural planning and fire engineering are supported. These models are implemented as XML-based models which can be accessed by mobile agents for information retrieval and for processing tasks. Agents are provided to all planners, they are enabled to check up the distributed design models with the knowledge base of the fire protection regulations,. With the use of such an agent each planner is supported to check up his planning for accordance with the fire protection requirements. The fire-engineering-agent analyzes the design and detects inconsistencies by processing fire protection requirements and design model facts in a rule-based expert system. The possibility to check the planning information at an early state in the sense of compatibility to the fire protection regulations enables a comprehensive diagnosis of the design and the reduction of planning errors. 2004 urn:nbn:de:gbv:wim2-20111215-1447 10.25643/bauhaus-universitaet.144 Professur Informatik im Bauwesen OPUS4-164 Konferenzveröffentlichung Rueppel, Uwe; Klauer, Thomas Internet-based Workflow-Management for Civil Engineering Projects The growing competition pressure in the building industry increases the demands on the design and construction processes in respect to economical, technical and time aspects. These demands require efficient improvements of the value-added chain, which can be realized mainly with the usage of innovative information- and communication-technologies. To support the collaboration of all participants involved in a certain building project the Workflow-Management-System "BauKom-Online" has been developed. In the focus of the system is to support the coordination of the participants and their information exchange. Such a software-method is well suited to ensure a high quality planning process. The modelling of business-processes enables a better self-comprehension of the participants work and helps to enhance the project performance. The system architecture of BauKom-Online contains two basic components: the processmodelling tool and the workflow-engine. The process-model contains of activities and states of the planning and construction processes and their relations. These connected processes compose the workflow. Such a process-model for engineering purposes has to satisfy several needs, e.g., the consideration of planning and building alternatives, dynamic changes of the model during execution of the project and the linkage to further technical objects like costs, building structure, specifications and documentmanagement. Furthermore, the scheduling of the project can be done within the process-model and can be visualized as a Gantt-diagram. ... 2004 urn:nbn:de:gbv:wim2-20111215-1647 10.25643/bauhaus-universitaet.164 Professur Informatik im Bauwesen OPUS4-141 Konferenzveröffentlichung Hartmann, Dietrich; Meißner, Udo F.; Rueppel, Uwe Integration of Productmodel Databases into Multi-Agent Systems This paper deals with two different agent-based approaches aimed at the incorporation of complex design information into multi-agent planning systems. The first system facilitates collaborative structural design processes, the second one supports fire engineering in buildings. Both approaches are part of two different research projects that belong to the DFG1 priority program 1103 entitled "Network-based Co-operative Planning Processes in Structural Engineering" (DFG 2000). The two approaches provide similar database wrapper agents to integrate relevant design information into two multi-agent systems: Database wrapper agents make the relevant product model data usable for further agents in the multi-agent system, independent on their physical location. Thus, database wrapper agents act as an interface between multi-agent system and heterogeneous database systems. The communication between the database wrapper agents and other requesting agents presumes a common vocabulary: a specific database ontology that maps database related message contents into database objects. Hereby, the software-wrapping technology enables the various design experts to plug in existing database systems and data resources into a specific multi-agent system easily. As a consequence, dynamic changes in the design information of large collaborative engineering projects are adequately supported. The flexible architecture of the database wrapper agent concept is demonstrated by the integration of an XML and a relational database system. 2004 urn:nbn:de:gbv:wim2-20111215-1410 10.25643/bauhaus-universitaet.141 Professur Informatik im Bauwesen OPUS4-161 Konferenzveröffentlichung Rueppel, Uwe; Gutzke, Thomas Groundwater-Monitoring based on dynamic co-operative eGovernment-Processes As a result of the pilot-project "Grundwasser-Online" the supervision and the active controlling of large monitoring- and catchment-areas are realised by a co-operative integration of all related institutions, a synchronisation-process to combine all distributed data into one central server database, and a high-level eGovernment-Service to provide evaluated information over the internet. Based on this software system the local authorities are able to supervise the groundwater-levels and to find adequate decisions, which finally result in official permissions for the usage of groundwater-reservoirs by the water supply companies. 2004 urn:nbn:de:gbv:wim2-20111215-1611 10.25643/bauhaus-universitaet.161 Professur Informatik im Bauwesen OPUS4-95 Konferenzveröffentlichung Katzenbach, Rolf; Meißner, Udo F.; Rueppel, Uwe Abstraction of Process Relevant Information from Geotechnical Standards and Regulations The paper presents the abstraction of process relevant information in order to enable the workflow management based on semantic data. It is shown for three examples, how the standards define the information needed to perform a certain planning activity. Abstraction of process relevant information is discussed for different granularities of the underlying processmodel. As one possible application ProMiSE is introduced, which uses process relevant data in individual tokens in a petri-net based process-model. 2004 urn:nbn:de:gbv:wim2-20111028-1002 10.25643/bauhaus-universitaet.95 Professur Informatik im Bauwesen OPUS4-133 Konferenzveröffentlichung Rueppel, Uwe; Meißner, Udo F.; Greb, Steffen A Petri Net based Method for Distributed Process Modelling in Structural Engineering The contribution introduces a method for the distributed process modelling in order to support the process orientation in Structural Engineering, i.e., the modelling, analysis and management of planning processes. The approach is based on the Petri Net theory for the modelling of planning processes and workflows in Structural Engineering. Firstly, a central and coarse process model serves as a pre-structuring system for the detailed modelling of the technical planning activities. Secondly, the involved planning participants generate distributed process models with detailed technical workflow information. Finally, these distributed process models will be combined in the central workflow net. The final net is of great importance for the process orientation in Structural Engineering, i.e., the identification, publication, analysis, optimization and finally the management of planning processes. 2004 urn:nbn:de:gbv:wim2-20111215-1338 10.25643/bauhaus-universitaet.133 Professur Informatik im Bauwesen
