An analyst represents a project manager, planner or any other person, involved in the planning process. Today, planning processes are managed by several geographically distributed planners and project managers. Thus, complexity of such a process rises even more. Prediction of consequences of many planning decisions is not possible, in particular since assessment of a planning advance is not trivial. There have to be considered several viewpoints, that depend on individual perceptions. In the following, methods are presented to realize planning decision support. 2004 urn:nbn:de:gbv:wim2-20111215-1370 10.25643/bauhaus-universitaet.1370 Professur Informatik im Bauwesen OPUS4-136 Konferenzveröffentlichung Miles, John; Joita, Liviu; Burnap, Peter Collaborative Engineering: Virtual Teams in a Grid Environment Supporting Consortia in the Construction Industry In the AEC (Architecture / Engineering / Construction) industry a number of individuals and organisations collaborate and work jointly on a construction project. The resulting consortium has large pool of expertise and experience and can be defined as a Virtual Organisation (VO) formed for the duration of the project. VOs are electronically networked organisations where IT and web based communication technology play an important role in coordinating various activities of these organisations. This paper describes the design, development and implementation of a Grid enabled application called the Product Supplier Catalogue Database (PSCD) which supports collaborative working in consortia. As part of the Grid-enabling process, specialised metadata is being developed to enable PSCD to effectively utilise Grid middleware such as Globus and Java CoG toolkits. We also describe our experience whilst designing, developing and deploying the security service of the application using the Globus Security Interface (GSI). 2004 urn:nbn:de:gbv:wim2-20111215-1362 10.25643/bauhaus-universitaet.136 Professur Informatik im Bauwesen OPUS4-135 Konferenzveröffentlichung Olivier, A. H. An application-centred framework for distributed engineering applications The conceptual structure of an application that can support the structural analysis task in a distributed collaboratory is described in (van Rooyen and Olivier 2004). The application described there has a standalone component for executing the finite element method on a local workstation in the absence of network access. This application is comparable to current, local workstation based finite element packages. However, it differs fundamentally from standard packages since the application itself, and its objects, are adapted to support distributed execution of the analysis task. Basic aspects of an object-oriented framework for the development of applications which can be used in similar distributed collaboratories are described in this paper. An important feature of this framework is its application-centred design. This means that an application can contain any number of engineering models, where the models are formed by the collection of objects according to semantic views within the application. This is achieved through very flexible classes Application and Model, which are described in detail. The advantages of the application-centred design approach is demonstrated with reference to the design of steel structures, where the finite element analysis model, member design model and connection design model interact to provide the required functionality. 2004 urn:nbn:de:gbv:wim2-20111215-1353 10.25643/bauhaus-universitaet.135 Professur Informatik im Bauwesen OPUS4-134 Konferenzveröffentlichung Yahiaoui, Azzedine; Hensen, Jan; Soethout, Luc Developing CORBA-based distributed control and building performance environments by run-time coupling Communication software and distributed applications for control and building performance simulation software must be reliable, efficient, flexible, and reusable. This paper reports on progress of a project, which aims to achieve better integrated building and systems control modeling in building performance simulation by run-time coupling of distributed computer programs. These requirements motivate the use of the Common Object Request Broker Architecture (CORBA), which offers sufficient advantage than communication within simple abstraction. However, set up highly available applications with CORBA is hard. Neither control modeling software nor building performance environments have simple interface with CORBA objects. Therefore, this paper describes an architectural solution to distributed control and building performance software tools with CORBA objects. Then, it explains how much the developement of CORBA based distributed building control simulation applications is difficult. The paper finishes by giving some recommendations. 2004 urn:nbn:de:gbv:wim2-20111215-1347 10.25643/bauhaus-universitaet.134 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
