Multi-site scheduling with fuzzy concepts

AbstractThe objective of multi-site scheduling is to support the scheduling activities of a global scheduler and schedulers in distributed production plants in a cooperative way. A global schedule generated on a global level must be translated into detailed schedules as part of the local scheduling process. In case of disturbance, feedback between the local and global levels is essential. Global level data are normally aggregated, imprecise, or estimated. Previous methods focused on local production sites, in most cases without coordination. In this work we present an approach that considers the adequate modeling and processing of imprecise data for global level scheduling within a multi-site scheduling system based on fuzzy concepts. One of the goals is to create a robust prescription for the local scheduling systems which helps to reduce the effort of coordination and rescheduling

Methods to Manage Information Sources for Software Product Managers in the Energy Market - A Reference Model Catalog for the Energy Market

The German energy market is facing several challenges due to changes in regulation, technical advancements as well as increasing energy costs and climate achievements like CO2 reduction. This results in changing requirements for companies in the energy market and thus business information systems, which support their core tasks and processes. Software product managers in energy and software developing companies in charge of driving the functional development of information systems have to deal with these challenges and need to develop new information systems or enhance existing ones. Conceptual models proved helpful to design and implement information systems within several industries. However, identification and management of models as well as impact analysis of model changes results difficult. This contribution describes methods to construct, use and maintain a domain specific reference model catalogue to support requirements analysis for software product manager in the German electricity and gas market

Internet of Energy - ICT as a Key Technology for the Energy System of the Future

Since the appearance of the special focus of “IT in the Utilities Industry” (WI 49) in the journal WIRTSCHAFTSINFORMATIK in autumn 2007, a dynamic development has taken place in the field. The ongoing effects of liberalization and the accelerated development of renewable energies have driven sustainable market changes leading to a transformation of the in- dustry. In parallel, the research program E-Energy of the Federal German Government started in 2008. Within this framework, projects in six model regions applied novel concepts and conducted systematic empirical research with extensive field trials. The federal research program in the field of infrastructure and processes for electric mobil- ity also played an important role in the research landscape of the recent years

Jörg Bleckmann – Ehrensenator der Carl von Ossietzky Universität Oldenburg

Am 5. November 2008 wurde Herrn Dr. Jörg Bleckmann in einem Festakt die Würde eines Ehrensenators der Carl von Ossietzky Universität verliehen. Die Vizepräsidentin der Universität, Dr. Heide Ahrens, betonte in ihrer Ansprache das breite und erfolgreiche Engagement, mit dem sich der neue Ehrensenator seit Jahrzehnten für die Carl von Ossietzky Universität, nicht zuletzt als Vorsitzender der Universitätsgesellschaft, eingesetzt hat. Prof. Dr. Dr. h.c. Hans-Jürgen Appelrath zeichnete in seiner ausführlichen Laudatio den beruflichen Werdegang Jörg Bleckmanns nach, den er in vergleichende Perspektive zu der Geschichte der Universität Oldenburg stellte. Ehrensenator Dr. Jörg Bleckmann brachte in seiner Dankesrede seine Verbundenheit gegenüber der Universität zum Ausdruck, zusammen mit einem lebhaften Plädoyer für die nachhaltige Verbindung von Forschung, Lehre und Praxis und kritischen Anmerkungen zu den Auswirkungen der Exzellenz-Initiative

Energy Informatics - Current and Future Research Directions

Due to the increasing importance of producing and consuming energy more sustainably, Energy Informatics (EI) has evolved into a thriving research area within the CS/IS community. The arti- cle attempts to characterize this young and dynamic field of research by de- scribing current EI research topics and methods and provides an outlook of how the field might evolve in the fu- ture. It is shown that two general re- search questions have received the most attention so far and are likely to dominate the EI research agenda in the coming years: How to leverage infor- mation and communication technol- ogy (ICT) to (1) improve energy effi- ciency, and (2) to integrate decentral- ized renewable energy sources into the power grid. Selected EI streams are reviewed, highlighting how the re- spective research questions are broken down into specific research projects and how EI researchers have made con- tributions based on their individual academic background
