  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  = {The general motivation of this research is to develop software to support the handling of the increased complexity of architectural design. In this paper we describe a system providing general support during the whole process. Instead of only developing design tools we are also addressing the problem of the operating environment of these tools. We conclude that design tools have to be integrated in an open, modular, distributed, user friendly and efficient environment. Two major fields have to be addressed - the development of design tools and the realisation of an integrated system as their operation environment. We will briefly focus on the latter by discussing known technologies in the field of information technology and other design disciplines that can be used to realise such an environment. Regarding the first subject we have to state the need of a detailed tool specification. As a solution we suggest a strategy where the tool functions are specified on the basis of a transformation, where a hierarchical process model is mapped into specifications of different design tools realising appropriate support for all sub-processes of architectural design. Using this strategy the main steps to develop such a support system are: implementation of a framework as basis for the integrated design system decision whether the tool specification are already implemented in available tools in this case these tools can be integrated using known methods for tool coupling otherwise new design tools have to be developed according to the framework},

  abstract  = {The construction industry is a project-based business bringing together many different organisations to complete a desired goal. The strategic use of Information and Communication Technologies (ICT) has enabled this goal to be completed more effectively. Two issues require addressing, the technology itself and the implementation factors of the technology. Such implementation factors should consider, among other factors, the legal and contractual issues associated with the use of ICT, training requirements and its effects on the organisational culture. To date the legal and contractual issues have not been extensively covered, and it is recognised that the technologies have not been properly covered by any recognised legal and contractual practices. This in turn is threatening to inhibit the growth and prosperity of the use of the technology on construction projects. This paper discusses these legal and contractual issues and describes methods and tools that can be used to enable the growth of technology to be used in a legal and contractually valid environment.},

The model provides the capability of simultaneous minimization of both project duration and work interruptions for construction crews. The model provides in a single run, a set of nondominated solutions that represent the tradeoff between these two objectives. The model incorporates a multiobjective genetic algorithm and scheduling algorithm. The model initially generates a randomly selected set of solutions that evolves to a near optimal set of tradeoff solutions in subsequent generations. Each solution represents a unique scheduling solution that is associated with certain project duration and a number of interruption days for utilized construction crews. As such, the model provides project planners with alternative schedules along with their expected duration and resource utilization efficiency.},

  abstract  = {This paper reports on the latest results in the development of a new approach for simulating the thermal behavior of buildings that overcomes the limitations of conventional heat-transfer simulation methods such as FDM and FEM. The proposed technique uses a coarse-grain approach to model development whereby each element represents a complete building component such as a wall, internal space, or floor. The thermal behavior of each coarse-grain element is captured using empirical modeling techniques such as artificial neural networks (ANNs). The main advantages of the approach compared to conventional simulation methods are: (a) simplified model construction for the end-user; (b) simplified model reconfiguration; (c) significantly faster simulation runs (orders of magnitude faster for two and three-dimensional models); and (d) potentially more accurate results. The paper demonstrates the viability of the approach through a number of experiments with a model of a composite wall. The approach is shown to be able to sustain highly accurate longterm simulation runs, if the coarse-grain modeling elements are implemented as ANNs. In contrast, an implementation of the coarse-grain elements using a linear model is shown to function inaccurately and erratically. The paper concludes with an identification of on-going work and future areas for development of the technique.},

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.},

The software tool DOMEdesign supports the formal design process of lattice and grid shell structures based upon the laws of physics. The computer-aided simulation of suspension models is used to derive structurally favourable forms for domes and arches subject to compression load, based upon the input of simple architectonic parameters. Irregular plans, three-dimensional topography, a choice different kinds of shell lattice structures and the desired height of the dome are examples of design parameters which can be used to modify the architectural design. The provision of data export formats for structural dimensioning and visualisation software enables engineers and planners to use the data in future planning and to communicate the design to the client.},

(305 m) long concrete bridge in the State of Vermont, located in the North East of USA. It is scheduled for renovation, in which the deck and its side parapet walls will be replaced. New England Transportation Consortium (NETC) decided to make further use of this project to find what effect will the heavy demolition tools have on the concrete to remain in place. The goal is to find out the extent of the experimental measurement agreement with the analytical results. In order to accomplish such a goal, numerous strain gages were installed at and in the vicinity of the demolition areas. Those gages will measure the effect of the demolition on the adjacent areas, and how far the destructive effect of the powerful demolition tools can propagate through different parts of the structure. The gages are connected to National Instruments data acquisition equipment, which is connected to a lap top computer to save all the acquired data. The analytical part the project will be using the energy method, which means that the energy applied by the demolition tools should equal the energy absorbed by the demolished structure, in elastic and plastic deformation forms.},

  abstract  = {This is a paper about knowledge in design and how to elicit knowledge from design processes. The paper is a preparation for an empirical study of interaction in the design process. Reasonings of three authors - Sch{\"o}n, Broadbent and Lundequist - on design processes is presented. They all have a pragmatic perspective in common, and regard the process as an activity without a definite form. Design is seen as an activity of creating models of forms and shapes, by addressing expert knowledge ­ in a dialogic way ­ to problematic situations. Due to the pragmatic approach I find the pragmatist Dewey´s understanding of knowledge and elecitation of knowledge appropiate for studying design processes. According to him it is possible to build up objectified descriptions of experiences, also of such, which are based on experiences of emotional and intuitive nature. There need not be a definite border, which separates tacit knowledge from explicit knowledge - when it comes to the question of the possibility of verbal descriptions. Tacit knowledge is possible to articulate within pragmatic thinking. The conclusion is, that it is possible to study the tacit knowledge of design processes, and get some qualitative insights useful for theory building. A study of design processes can look at three different forms of knowledge. It appears as a pre­cognitive understanding of the design situation, as integrated in the design activity - seeing the situation as something known - and in the process of creating something new.},

Yet almost every conceptual modelling or software development project starts by defining the business processes to be supported and the related requirements to be satisfied. This paper describes a new process-centred methodology for user requirements capture developed in the ICCI project (IST-2001-33022). Its essence is in recognising user requirements and use cases in the context of the real construction process, identifying the actors and roles for each individual activity and associating these activities with information, communication and standardisation requirements on the basis of a formalised specification, named the Process Matrix. In the paper we outline the history of process matrix development, introduce the basic structure of the matrix and show how it can be further extended and refined. We present also a web-based software implementation of the developed approach, describe how it has been used in ICCI and outline further perspectives.},

  abstract  = {Informations-und Kommunikationtechniken haben im Bauwesen noch nicht die gew{\"u}nschten Vorteile f{\"u}r Kosten und Qualit{\"a}t von Bauobjekten erzielt. Die Vielfalt der daf{\"u}r genutzten Systeme und Formate f{\"u}hrt h{\"a}ufig zu Redundanzen und Informationsverlusten in den Planungs- und Bauprozessen sowie Problemen beim Datenaustausch zwischen den Systemen. Durch die Datenmengen, die in CAD, AVA, Terminplanung, Tabellenkalkulation, Textverarbeitung etc. durch unterschiedliche Beteiligte erzeugt werden, ist dar{\"u}ber hinaus das Risiko einer unterschiedlichen Datenaktualit{\"a}t enorm. Als Konsequenz dieser Erkenntnisse bestand die Aufgabe, eine ganzheitliche und durchg{\"a}ngige Produkt- und Prozeßstrategie f{\"u}r den preiswerten Einfamilienhausbau zu entwickeln. Die Grundlage daf{\"u}r bildet ein komplexes System von rationellen Entwurfsregeln, Konstruktionsl{\"o}sungen und Bau- und Baustofflogistikkonzepten auf der Basis moderner Informations- und Kommunikationstechnologien.},

  abstract  = {For modeling of singular fields of stresses and deformations in elasters with a crack is offered to use of three-dimesional a special finite element. Weak compessible of elasters is taken into account on the basis of threefold approximation of fields of displacements, deformations and function of volume change. At intensive cyclic loading of the elastomer constructions with a crack it is necessary to take into account warming and large deformations at the crack top. The stress-deformed state elasters with a crack is determined from the decision of a nonlinear problem by a modified method Newton-Kantorovich. Account stress intensity factors for a rectangular plate with a various arrangement of a through crack is executed. Process of development of a surface crack and dissipative warming in prismatic a element of shift is investigated.},

  abstract  = {The goal of the research is the development of a computer system to plan, simulate and visualize erection processes in construction. In the research construction cranes are treated as robots with predefined degrees of freedom and crane-specific motion planning techniques are developed to generate time-optimized and collision-free paths for each piece to be erected in the project. Using inverse kinematics and structural dynamics simulation, the computer system then computes the crane motions and velocities necessary to achieve the previously calculated paths. The main benefits of the research are the accurate planning and scheduling of crane operations leading to optimization of crane usage and project schedules, as well as improving overall crane safety in the project. This research is aimed at the development of systems that will allow computer-assisted erection of civil infrastructure and ultimately to achieve fully-automated erection processes using robotic cranes...},

  abstract  = {Buildings require both for construction and, due to their comparatively long life cycle for maintenance, significant raw material and energy resources. So far available knowledge about resource consumption during an entire life cycle of a building is still quite rare, because various criteria affect each other and/or overlay mutually. In this contribution a model based software concept is presented using an integrated approach for life cycle simulation and assessment of buildings. The essential point of the development consists of connecting an IFC compliant product model of a building via the Internet with data bases for the resource and energy requirement of building materials. Furthermore, numerical simulations allow calculating and minimizing the energy consumption, the resource requirement, the waste streams and also the noxious emissions. In the context of this paper we present the first release of software programs for architects and engineers, which help them to evaluate their design decisions objectively in early planning steps. Additionally the usage of the software is demonstrated by a test case study for a real world building. By applying this software in practice a substantial contribution for saving energy and natural resources can be provided in the sense of sustainable and ecological building design.},

  abstract  = {Re-examination of the behaviour of structures can be necessary due to deterioration or changes in the traffic situation during their lifetime. The Finite Element Method (FEM) is widely used in order to accomplish numerical analysis. Considering the development of computer performance, more detailed FEM models can be analyzed, even on site, with mobile computers. To compensate the increasing amount of data needed for the model input, measures need to be taken to save time, by distributing the work. In order to provide consistency to the model, fedback data must be checked upon reception. A local wireless computer network of ultra-portable devices linked together with a computer can provide the coordination necessary for efficient parallel working. Based on a digital model consisting of all data gathered, structural modelling and numerical analysis are performed automatically. Thus, the user is released from the work that can be automatized and the time needed for the overall analysis of a structure is decreased.},

  abstract  = {The paper presents a general map-based approach to prototyping of products in virtual reality environments. Virtual prototyping of products is considered as a consistent simulation and visualization process mapping the source product model into its target visual representations. The approach enables to interrelate formally the product and visual information models with each other by defining mapping rules, to specify a prototyping scenario as a composition of map instances, and then to explore particular product models in virtual reality environments by interpreting the composed scenario. Having been realized, the proposed approach provides for the strongly formalized method and the common software framework to build virtual prototyping applications. As a result, the applications gain in expressiveness, reusability and reliability, as well as take on additional runtime flexibility...},

  abstract  = {In current AEC practice client requirements are typically recorded in a building program, which, depending on the building type, covers various aspects from the overall goals, activities and spatial needs to very detailed material and condition requirements. This documentation is used as the starting point of the design process, but as the design progresses, it is usually left aside and changes are made incrementally based on the previous design solution. These incremental small changes can lead to a solution that may no longer meet the original requirements. In addition, design is by nature an iterative process and the proposed solutions often also cause evolution in the client requirements. However, the requirements documentation is usually not updated accordingly. Finding the latest updates and evolution of the requirements from the documentation is very difficult, if not impossible. This process can lead to an end result, which is significantly different from the documented requirements. Some important requirements may not be satisfied, and even if the design process was based on agreed-upon changes in the scope and requirements, differences in the requirements documents and in the completed building can lead to well-justified doubts about the quality of the design and construction process...},

  abstract  = {The goal of the research is to increase the understanding of dynamic behaviors during the crane operation, and develops computer-aided methods to improve the training of crane operators. There are approximately 125,000 cranes in operation today in the construction industry, responsible for major portion of erection activities. Unfortunately, many accidents occur every year in the U.S. and other countries related to the operation of cranes in construction sites. For example on November 28, 1989 a tower crane collapse during the construction of a building in San Francisco killing four construction workers, one civilian and injuring 28. According to the statistics from Occupational Safety Health Administration (OSHA), there were 137 crane-related fatalities from 1992 to 2001 in the US. A well-known internet website that keeps track of crane-related accidents (craneaccidents.com), reports 516 accidents and 277 fatalities from 2000 to 2002. These statistics show that even though many measures have been taken to decrease the number of crane-related accidents (Braam, 2002), the number of crane related accidents is still very large. It is important to recognize that each construction related fatality is not only a great human loss but also increases the costs of insurance, lawsuits, and the construction budget due to delay of a project (Paulson 1992)...},
