In large-scale shop floors and manufacturing environment, different transportation systems are applied in order to satisfy the material requirements of the systems. The limited capacity of vehicles and time consumption of the logistics processes require effective vehicle routing approaches so as to support production without glitches. The paper gives an overview of the appropriate models and the most efficient solver algorithms of the vehicle routing problem (VRP), introduces a novel approach that uses a novel initial solution generation heuristics, and presents a local search method to solve the VRP. In order to demonstrate the capabilities of the solution proposed, the implemented software concentrates on the main industrial requirements like quick response, effective layout definition and order handling. A specific layout representation scheme is proposed which ensures interoperability between different factory-, and shop-floor planning software products. © 2013 The Authors.

Medium-term sales and operations as well as medium to short-term production planning in customer order driven production processes are performed using a cascading planning process. A lack of coordination and feedback between different planning phases causes problems with a negative effect on costs in production that originate from unfeasible production programs. Based on a system for the classification of planning restrictions the planning process will be controlled utilizing a newly developed combination of the methods of Linear Programming and Constraint Programming. The result is a formal logic to combine the different planning horizons and the two sets of planning methods. © 2012 CIRP.

The purpose of this paper is to provide an enabler-based approach for a supervised self-assessment of operations excellence (OsE). Based on the latest approaches of excellence in operations from the literature as well as on the philosophy of the EFQM model, an OsE working definition was developed. In contrast to operational excellence (OE), which deals exclusively with the optimization of result driven processes, OsE promotes the enhancement of operation-specific enablers and linked results. The evaluation of crucial cause–effect relationships of relevant enabler and result criteria supports the determination of a company’s capability to achieve sustainability and excellence in terms of its operations. To foster a methodical integration of OsE in organizations, a phase model for a systematic assessment process was designed and verified with 24 companies in the Austrian machinery and metalware industries. © 2016 The Author(s)

With increasing knowledge the process of knowledge management and engineering becomes more and more important. Enriching documents by using markup techniques and by supporting semantic annotations is a major technique for knowledge management. This invaluable information is of extreme importance in the context of civil engineering, product life cycle management, virtual archival storage, and preservation. In these fields of applications annotation techniques for 3D documents are a vital part. They provide semantic information that makes up the basis for digital library services: retrieval, indexing, archival, and searching. Furthermore, metadata are of significant importance as they set the stage for data re-use and they provide documentation of data sources and quality, which is vital for every engineering department. Using metadata helps the user to understand data. Additional information allows focusing on key elements of data that help to determine the data's fitness for a particular use and may provide consistency in terminology. In this paper we give an overview on state-of-the-art annotation techniques focussed on 3D data.

Mesoscale experiment and simulation permit harvesting information about both geometric features and texture in polycrystals. The grain boundary character distribution (GBCD) is an empirical distribution of the relative length [in two dimensions (2D)] or area (in 3D) of an interface with a given lattice misorientation and normal. During the growth process, an initially random distribution of boundary types reaches a steady state that is strongly correlated to the interfacial energy density. In simulation, it is found that if the given energy density depends only on lattice misorientation, then the steady-state GBCD and the energy are related by a Boltzmann distribution. This is among the simplest nonrandom distributions, corresponding to independent trials with respect to the energy. In this paper, we derive an entropy-based theory that suggests that the evolution of the GBCD satisfies a Fokker-Planck equation, an equation whose stationary state is a Boltzmann distribution. Cellular structures coarsen according to a local evolution law, curvature-driven growth, and are limited by space-filling constraints. The interaction between the evolution law and the constraints is governed primarily by the force balance at triple junctions, the natural boundary condition associated with curvature-driven growth, and determines a dissipation relation. A simplified coarsening model is introduced that is driven by the boundary conditions and reflects the network level dissipation relation of the grain growth system. It resembles an ensemble of inertia-free spring-mass dashpots. Application is made of the recent characterization of Fokker-Planck kinetics as a gradient flow for a free energy in deriving the theory. The theory predicts the results of large-scale two-dimensional simulations and is consistent with experiment. © 2011 American Physical Society.

The main, overall objective of the proposal is to establish the Centre of Excellence in Production Informatics and Control (EPIC) as a leading, internationally acknowledged focus point in the field of production informatics, management and control representing excellence in R&D&I. EPIC will be constituted and run through the cooperation of the Institute for Computer Science and Control, Hungarian Academy of Sciences (MTA SZTAKI), two faculties of the Budapest University of Technology and Economics (BME) and four institutions of the Fraunhofer-Gesellschaft (FhG) under the coordination of the National Innovation Office (NIH), Hungary as a governmental decision maker. The EPIC project will lead to: 1. The upgrade of MTA SZTAKI as existing Centre of Excellence of the EU. 2. The further development of the Fraunhofer-SZTAKI Project Centre for Production Management and Informatics (PMI), a joint initiative of FhG and the Hungarian Academy of Sciences (MTA), established in 2010. (The cooperating Fraunhofer institutions have been the Fraunhofer Institute for Manufacturing Engineering and Automation (IPA), Stuttgart and Fraunhofer Austria (FhA)). 3. The extension of the present cooperation with two faculties of BME, i.e., the Faculty of Mechanical Engineering (GPK) and the Faculty of Transportation Engineering and Vehicle Engineering (KJK), on the one hand, and with two additional institutes of FhG, i.e., the Institute for Production Technology (IPT), Aachen and the Institute for Production Systems and Design Technology (IPK), Berlin. 4. The close cooperation with SMEs as well as with large industrial firms. Due to direct, institutionalized and supported interactions with Fraunhofer, not only the scientific capabilities of the Hungarian partners but also their ability to transfer scientific results to industry-relevant applications will be greatly enhanced. By this way a high speed lift to innovation culture and performance in Hungary and the CEE region will be provided.

Along with the paradigm shift that changed the way of architectural drafting from 2D analog plans and scale models over 2D digital plans to complex digital 3D models, the importance for libraries, museums, and archives for long-term preservation of architectural digital 3D models was recognized some years ago. To this end, research projects trying to set up a process to capture, describe, manage, preserve, and make available digital CAD models created by architects during building projects were established in the United States as well as in Europe. Despite the shift from analog to digital representations, the access mechanisms of current long-term archiving systems in the architectural domain are still based on simple metadata schemes inherited from the analog world and therefore limited in the same way as searching with a card index in the analog age. The potential inherent in a full digital representation is not exploited so far as detailed semantic information in the digital documents is either not available or simply not used for retrieval. In the DuraArK project we will develop a long-term preservation system for architectural content that will overcome these shortcomings. It will allow searching and accessing data on different semantic levels going far beyond the possibilities of currently used metadata schemes. At the same time, it will provide secure and future-proof data storage by tackling the problems arising from digital decay.

Business networking strategies and especially cooperation in logistics are gaining momentum for individual companies in order to survive in competitive markets. As horizontal logistics cooperation among shippers is a new and powerful approach to optimize cost structures, this publication deals with the conceptual design and the organizational aspects of horizontal cooperation. With regard to the variety of influencing factors and parameters of cooperation a framework is presented that supports the selection of possible cooperation forms. Special attention is further dedicated to the design of cooperative logistics models as well as to the specifications of cooperation models, which are both considered as key factors to ensure a successful and sustainable cooperation. Based on the identified structural concepts the great potential of horizontal logistics cooperation is demonstrated on the example of two case studies. © 2011 CIRP.

Vienna, 23.02.2017 The key to a well-designed airport is to understand how passengers interact with their environment and how visual information influences their orientation and navigation behavior. Of particular importance is wayfinding information, which often competes with other visual stimuli such as advertising. Wayfinding has to be an integral part of the design process to create more intuitive architectural spaces where passengers navigate instinctively. Evaluating the design from a passenger's wayfinding perspective already in the planning phase can prevent wrong design choices which might result in higher costs at later stages. EXPERIENCE is a consulting service based on virtual reality technologies which offers a novel method for an interactive exploration and analysis of architectural models and designs before they are built. It uses a test environment allowing persons to walk through virtual 3D models of airports while measuring their movement, visual attention and relevant behavioral characteristics. For a high level of realism, EXPERIENCE combines immersive visual computing technologies, characteristic soundscapes and cutting-edge crowd simulations - based on the framework SIMULATE, which is also used for evacuation and capacity analysis of infrastructures. As a result, the passenger wayfinding experience can be evaluated by quantifying several passenger-oriented aspects (detailed passenger-route-analysis, visibility of static and dynamic signage, etc.) in customized scenarios with a representative cross-section of user groups (age, nationality, etc.). EXPERIENCE was developed by experts from the AIT Austrian Institute of Technology Center for Mobility Systems in close cooperation with Fraunhofer Austria Research GmbH. This collaboration enabled the development of an ideal solution for architects, operators of large infrastructures and public spaces, transportation planners and consultants. It effectively supports the evaluation of architecture and identifies issues ahead of time, resulting in reduced need for re-work and project cost savings. As such it revolutionizes wayfinding planning processes and enables to test the acceptance of the terminal visibility as a whole or of its subsystems and components. EXPERIENCE improves pedestrian flows - as well as the performance of designs - and increases customer satisfaction leading to greater usage and turnover. EXPERIENCE was successfully used in the planning phase of Vienna's new Central Railway Station to improve the guidance of people through the facility.
