  abstract  = {Projektsteuerung gewinnt als Aufgabenfeld bei der Realisierung von Investitionsprojekten st{\"a}ndig an Bedeutung. Zur Bew{\"a}ltigung der umfangreichen und komplizierten Aufgaben des Projektsteuerers wird zunehmend Software angeboten und genutzt. Dabei ist feststellbar, daß von einer integrierten Projektsteuerung unter Ber{\"u}cksichtigung der Kriterien Leistung, Termin und Kosten nicht gesprochen werden kann, weil wesentliche theoretische und praktische Voraussetzungen fehlen. Im Beitrag werden Defizite der praktizierten Vorgehensweise und L{\"o}sungsans{\"a}tze f{\"u}r eine integrierte rechnergest{\"u}tzte Projektsteuerung vorgestellt. Durch geeignete Formen der Projektstrukturierung und eine Kopplung auf dem Mark befindlicher Standardsoftware k{\"o}nnen geeignete L{\"o}sungen gefunden werden. Problempunkte dabei stellen die Schnittstellen zwischen den Anwenderprogrammen die Datenbeschaffung und -verwaltung sowie geeignete Verfahren zur Kostenermittlung und -verfolgung dar. Im Beitrag werden eine bereits praktizierte und eine in Entwicklung befindliche L{\"o}sung vorgestellt.},

  abstract  = {Seit die Datenverarbeitung in ihrer Komplexit{\"a}t sich der Thematik des Computer Integrated Manufacturing widmet geh{\"o}rt die Produktionsplanung und Steuerung zu jenen Bereichen, in denen eine Computerunterst{\"u}tzung am vordringlichsten erschien. Sp{\"a}ter sind betriebswirtschaftliche Gesamtl{\"o}sungen entstanden, die (bis heute recht unpr{\"a}zise) als Enterprise Resource Planning (ERP)-Systeme bezeichnet werden und in ihren Logistik-Modulen auch Funktionen der Produktionsplanung abdecken. Alle bekannten MRP-, PPS- und auch ERP-Systeme beruhen auf einer Sukzessivplanung. Advanced Planning and Scheduling (APS) Systems finden seit etwa 1995 zunehmend Interesse. Neben Demand Planning, Production Planning and Scheduling, Distribution Planning, Transportation Planning und Supply Chain Planning werden L{\"o}sungen f{\"u}r Anzahl und Standorte von Produktionsst{\"a}tten und Auslieferungslagern, Zuordnung zu Produktionsst{\"a}tten, Kapazit{\"a}tsbestimmung f{\"u}r Arbeitskr{\"a}fte und Betriebsmittel je Standort, Lagerhaltung je Teil und Lager, Bestimmung ben{\"o}tigter Transportmittel und H{\"a}ufigkeit ihres Einsatzes, Zuordnung von Lagern zu Produktionsst{\"a}tten von M{\"a}rkten zu Lagern u.a.m. von APS-Systemen erwartet. D.h. APS-Systeme erg{\"a}nzen ERP-L{\"o}sungen, nutzen die bereits durch das ERP-System vorhandenen Daten und ben{\"o}tigen neuartige Algorithmen und (Meta-) Heuristiken. Im Rahmen des Vortrages werden Modelle und Echtzeitalgorithmen zur Optimierung der Logistik f{\"u}r Prozesse mit kurzfristigen Anforderungen, geographisch verteilter Produktion, Lagerhaltung der Ausgangs-, Zwischen- und Endprodukte und wechselnden Transport-Bedingungen aus der Sicht der praktischen Umsetzung und Anwendung in Form einer ASP-L{\"o}sung aufgezeigt und diskutiert.},

  abstract  = {Our proposed solution is to enable partners of a construction project to share all the technical data produced and handled during the building production process by building a system through the use of internet technology. The system links distributed databases and allows building partners to access remotely and manipulate specific information. It provides an updated building representation that is being enriched and refined all along the building production process. A recent collaboration with Nemetschek France (subsidiary company of Nemetschek AG, AEC CAD software leader) focus on a building product repository available in a web context. The aim is to help building project actors to choose a technical solution that fits its professional needs, and maintain our information system with up to date information. It starts with the possibility to build on line building product catalogs, in order to link Allplan CAD entities with building technical features. This paper presents the conceptual approaches on which our information system is built. Starting from a general organization diagram organization, we focus on the product and the description branches of construction works (including last IFC model specifications). Our aim is to add decisional support to the construction works selection process. To do so, we consider the actor's role upon the system and the pieces of information each one needs to achieve a given task.},

  abstract  = {The management of resources is an essential task in each construction company. 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. ...},

  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.},

  abstract  = {The engineering and construction industry has been slow to exploit the full potential of information technology. The industry is highly fragmented, price sensitive, risk-adverse, and profit margins are small. Each project is unique with a small amount of technological innovation opportunities to capitalise on from one project to the next. Technological innovations that have been taking place are just simulating the old traditional paper workflow. Engineering information in digital form is being conveyed using traditional paper representations, which have to be interpreted by humans before the information can be used in other applications, thereby creating 'islands of information'. It can be seen that poorly implemented IT strategies are duplicating paperwork, rather than reducing or eliminating it (Crowley et al., 2000). This paper will introduce the Integrated Engineering Workflow (IEW) concept to re-organise a structural discipline working on multi-disciplinary projects so as to maximise the advantages offered by new information technology.},

  abstract  = {Applications for civil engineering tasks usually contain graphical user interfaces for the engineering processes. Persistent objects of the applications are stored to data bases. The influence of the interaction between a graphical user interface and a data base for the development of an civil engineering application is investigated in this paper. A graphic application for the linear elastic analysis of plane frames, which was previously developed with standard tools of the Java platform, is compared to a redesigned implementation using a generalized data base for persistent objects. The investigation leads to the following results : - A strict distinction between persistent and transient objects influences the class structure of an application, in particular the class structure of a graphical user interface. - The structure of an application depends on the logic for updating of references to persistent and transient graphical objects after an application is read from a file. - The complexity of the reference management can usually be handled better by just in time referencing associated with String - identifiers rather than by automated referencing associated with Name - identifiers.},

  abstract  = {The design of building projects involves several types of resources such as architects, structural engineers, mechanical engineers, electrical engineers, and draftsmen, among others. For design firms to stay in business in this very competitive market, they need to manage their resources in a way that improves productivity and cost effectiveness. This task, however, is not simple and requires thorough analysis of process-level operations, resource use, and productivity. Typically, these operational aspects are the responsibility of the design office manager who assigns available resources to the different design projects to save time and lower design expenses. It is noted that limited studies have been carried out in the literature to model overall organizational operations and behavioral aspects, particularly in firms specialized in the design of building projects. In an effort to simplify the modeling process, a simplified modeling and simulation tool is used in this research. A simulation model representing an actual design office was developed assuming that the office performs designs for small, medium, and large size building projects. The developed model was used to simulate several alternatives and examine various resource assignment strategies. The simulation was conducted over ten years and the resulting productivity and income was measured.},
