Today, ERP systems and e-Business systems are available to assist construction companies to efficiently organise the allocation of their personnel and equipment within the company, but they cannot provide the company with the idle resources for every single task that has to be performed during a construction project. Therefore, companies should have an alternative solution to better exploit expensive resources and compensate their fixed costs, but also have them available at the right time for their own business activities. This paper outlines the approach taken by the EU funded project "e-Sharing" (IST-2001-33325) to support resource management between construction companies. It will describe requirements for the management of construction resources, its core features, and the integration approach. Therefore, we will outline the approach of an integrated resource type model supporting the management and classification of construction equipment, construction tasks and qualification profiles. The development is based on a cross-domain analysis and evaluation of existing models. ...}, subject = {Baubetrieb}, language = {en} } @inproceedings{PerevalovaPahl2004, author = {Perevalova, Julia and Pahl, Peter Jan}, title = {Structural and Functional Dependence of Objects in Data Bases}, doi = {10.25643/bauhaus-universitaet.168}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20111215-1683}, year = {2004}, abstract = {Let the information of a civil engineering application be decomposed into objects of a given set of classes. Then the set of objects forms the data base of the application. The objects contain attributes and methods. Properties of the objects are stored in the attributes. Algorithms which the objects perform are implemented in the methods of the objects. If objects are modified by a user, the consistency of data in the base is destroyed. The data base must be modified in an update to restore its consistency. The sequence of the update operations is not arbitrary, but is governed by dependence between the objects. The situation can be described mathematically with graph theory. The available algorithms for the determination of the update sequence are not suitable when the data base is large. A new update algorithm for large data bases has been developed and is presented in this paper.}, subject = {Baubetrieb}, language = {en} } @inproceedings{KoenigKlingerBerkhahn2004, author = {K{\"o}nig, Markus and Klinger, Axel and Berkhahn, Volker}, title = {Structural Correctness of Planning Processes in Building Engineering}, doi = {10.25643/bauhaus-universitaet.169}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20111215-1690}, year = {2004}, abstract = {The planning of projects in building engineering is a complex process which is characterized by a dynamical composition and many modifications during the definition and execution time of processes. For a computer-aided and network-based cooperation a formal description of the planning process is necessary. In the research project "Relational Process Modelling in Cooperative Building Planning" a process model is described by three parts: an organizational structure with participants, a building structure with states and a process structure with activities. This research project is part of the priority program 1103 "Network-Based Cooperative Planning Processes in Structural Engineering" promoted by the German Research Foundation (DFG). Planning processes in civil engineering can be described by workflow graphs. The process structure describes the logical planning process and can be formally defined by a bipartite graph. This structure consists of activities, transitions and relationships between activities and transitions. In order to minimize errors at execution time of a planning process a consistent and structurally correct process model must be guaranteed. This contribution considers the concept and the algorithms for checking the consistency and the correctness of the process structure.}, subject = {Baubetrieb}, language = {de} } @inproceedings{MuellerKirschkeKoecheretal.2003, author = {M{\"u}ller, Jens and Kirschke, Heiko and K{\"o}cher, J{\"u}rgen and Petter, Steffen}, title = {Untersuchung und Erarbeitung eines Leitfadens zum Dokumentenmanagement in KMU des Bauwesens}, doi = {10.25643/bauhaus-universitaet.336}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20111215-3367}, year = {2003}, abstract = {In der heutigen Informationsgesellschaft sind alle Gesch{\"a}ftsprozesse in einem Unternehmen gepr{\"a}gt durch die Verwendung der vorhandenen Informations- und Kommunikationstechnologien.
