  abstract  = {In this contribution, the design of an analysis environment is presented, that supports an analyst to come to a decision within a gradual collaborative planning process. 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.},

  abstract  = {Building design in Civil Engineering is characterized by the cooperation of experts in multiple disciplines. 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.},

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).},

In this paper, a new approach based on octrees will be discussed. It will be shown that by the usage of octrees not only the management and control of processes in a network-based working environment can be optimised but also an efficient integration platform for processes from various disciplines - such as architecture and civil engineering - can be provided. By means of an octree-based collision detection resp. consistency assurance a client-server-architecture will be described as well as sophisticated information services for a further support of cooperative work.},

  abstract  = {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.},

  abstract  = {Bauwerke sind in der Regel Unikate, f{\"u}r die meist eine komplette und aufw{\"a}ndige Neuplanung durchzuf{\"u}hren ist. Der Umfang und die Verschiedenartigkeit der einzelnen Planungsaufgaben bedingen ein paralleles Arbeiten der beteiligten Fachplaner. Dar{\"u}ber hinaus ist die Bauplanung ein kreativer und iterativer Prozess, der durch h{\"a}ufige {\"A}nderungen des Planungsmaterials und Abstimmungen zwischen den Fachplanern gekennzeichnet ist. Mithilfe von speziellen Fachanwendungen erstellen die Planungsbeteiligten verschiedene Datenmodelle, zwischen denen fachliche Abh{\"a}ngigkeiten bestehen. Ziel der Arbeit ist es, die Konsistenz der einzelnen Fachmodelle eines Bauwerks sicherzustellen, indem Abh{\"a}ngigkeiten auf Basis von Objektversionen definiert werden. Voraussetzung daf{\"u}r ist, dass die Fachanwendungen nach dem etablierten Paradigma der objektorientierten Programmierung entwickelt wurden. Das sequentielle und parallele Arbeiten mehrerer Fachplaner wird auf Basis eines optimistischen Zugriffsmodells unterst{\"u}tzt, das ohne Schreibsperren auskommt. Weiterhin wird die Historie des Planungsmaterials gespeichert und die Definition von rechtsverbindlichen Freigabest{\"a}nden erm{\"o}glicht. Als Vorbild f{\"u}r die Systemarchitektur diente das Softwarekonfigurationsmanagement, dessen Versionierungsansatz meist auf einem Client-Server-Modell beruht. Die formale Beschreibung des verwendeten Ansatzes wird {\"u}ber die Mengenlehre und Relationenalgebra vorgenommen, so dass er allgemeing{\"u}ltig und technologieunabh{\"a}ngig ist. Auf Grundlage dieses Ansatzes werden Konzepte f{\"u}r den Einsatz versionierter Objektmodelle im Bauwesen erarbeitet und mit einer Pilotimplementierung basierend auf einer Open-Source-Ingenieurplattform an einem praxisnahen Szenario verifiziert. Beim Entwurf der Konzepte wird besonderer Wert auf die Handhabbarkeit der Umsetzung gelegt. Das betrifft im Besonderen die hierarchische Strukturierung des Projektmaterials, die ergonomische Gestaltung der Benutzerschnittstellen und der Erzielung von geringen Anwortzeiten. Diese Aspekte sind eine wichtige Voraussetzung f{\"u}r die Effizienz und Akzeptanz von Software im praktischen Einsatz. Bestehende Fachanwendungen k{\"o}nnen durch geringen Entwicklungsaufwand einfach in die verteilte Umgebung integriert werden, ohne sie von Grund auf programmieren zu m{\"u}ssen.},

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.},

Collaboration amongst team members seperated in time and location is of particular importance. Two broad themes can be recognized in research pertaining to distributed collaboration. One theme focusses on the technical and technological aspects of distributed work, while the other emphasises human aspects thereof. The case of finite element structural analysis in a distributed collaboratory is examined in this paper. An approach is taken which has its roots in human aspects of the structural analysis task. Based on experience of how structural engineers currently approach and execute this task while utilising standard software designed for use on local workstations only, criteria are stated for a software architechture that could support collaborative structural analysis. Aspects of a pilot application and the results of qualitative performance measurements are discussed.},

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.},
