- KonferenzbeitragExperimentplanung und -durchführung mit BPMN-Modellen im Windpark-Simulationswerkzeug DESMO-Windpark-Studio(Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Stehle, TilmannIm Umfeld der Energieerzeugung auf im Meer errichteten Windkraftanlagen au erhalb von K stenzonen, sogenannten Offshore Windparks, erschlie t sich ein neues Forschungsgebiet der Logistik. Im Rahmen des Projekts SystOp Offshore Wind sollen Betriebs- und Instandhaltungsprozesse des Leistungssystems Offshore Windpark optimiert werden. Dazu geh ren beispielsweise die Versorgung der Windkraftanlagen mit Ersatzteilen, oder Wartungsdienstleistungen, f r die der Einsatz von Schiffen oder Hubschraubern an den Anlagen notwendig ist. Aufgrund der besonderen Umgebung mit extremen Wettereinfl ssen und gesetzlichen Auflagen bez glich des Passierens von Staatsgrenzen, sowie der Notwendigkeit des Zusammenspiels verschiedener Akteure ist hierbei stets ein komplexer logistischer Zusammenhang gegeben. Aus diesem Grund werden Techniken und Methoden der Simulation eingesetzt, mit denen Analysen ber kritische Prozessfaktoren, R ckkopplungen und Engp sse der betroffenen Ressourcennutzer untersucht werden sollen, die direkt oder indirekt Einfluss auf Aspekte wie Sicherheitsrisiken der Prozesse, Verf gbarkeit der Anlagen, Stromgestehungskosten oder den Stromertrag nehmen. An der Universit t Hamburg entsteht zu diesem Zweck der Werkzeugkasten DESMO-Windpark -Studio, eine Software zur Modellierung und Simulation der abzubildenden Wettereinfl sse, Ressourcen, Gesch ftsprozesse und Windpark-Komponenten. Sie basiert auf der Plug-in-Rahmenanwendung Empinia und nutzt die quelloffene Simulationsbibliothek DESMO-J. Mit DESMOWindpark- Studio soll das Optimierungsvorhaben unter Durchf hrung wiederholter Simulationsl ufe und unter Variation der Modellparameter unterst tzt werden. Eine besondere Herausforderung ist unter anderem in der Heterogenit t der eingesetzten Modelle zu sehen, die gleichartig im Rahmen der Simulation parametrisiert und in mehrfache Simulationen eingebunden werden. DESMO-Windpark-Studio bietet inzwischen neben anderen Funktionalit ten den Import von BPMN-Modellen und bietet eine Experimentierumgebung, in der wiederholte Experimentl ufe unterschiedlich konfigurierter Modelle geplant und durchgef hrt werden k nnen. Der vorliegende Beitrag beschreibt diese Erweiterung der Software, die das Experimentieren mit BPMN-Kollaborationsmodellen in mehrl ufigen Experimenten unter Variation von Modellparametern erm glicht. Basierend auf dem aktuellen Stand der Software stehen prototypische Experimente mit Gesch ftsprozessmodellen in Aussicht. Dabei sollen durch die Universit t Bremen erhobene Betriebs- und Instandhaltungsprozesse in DESMO-Windpark-Studio simuliert werden. An dieser prototypischen Simulation sollen die Funktionsf higkeit von DESMO-Windpark-Studio, der Wert der erhobenen Modelle und gegebenenfalls erste Informationen ber Optimierungspotentiale der Prozesse untersucht werden.
- KonferenzbeitragClimate Change, Food Security and Informatics(Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Armbruster, Walter J; MacDonell, Margaret MIncreasing scientific evidence emphasizes the importance of addressing climate changes worldwide. While the relative roles of human versus natural causes continue to be disputed, evolving evidence supports the hypothesis that human activities have significantly contributed to substantial changes in climatic events, and these impacts are expected to continue (and increase) if activity patterns remain unchanged. The extent to which human activities must be adjusted to slow and reverse this trend remains under debate, but it is widely agreed that actions now will mitigate climate change impacts both in the near term and into the more distant future. This point is at the core of arguments for timely mitigation through various means to reduce the projected longer-term effects of climate change, including impacts on food security for the burgeoning human population. Efforts to adapt to climate change are under way, and further concerted planning and implementation strategies are needed. This paper explores implications of climate change for global food security due to increased variability in production year-to-year from droughts, extreme rain events and other weather-related phenomena. It addresses the shifts in climatic zones already being experienced and related impacts on the spread of plant and animal diseases; the potential impact of weather events on invasive pathogens and other species that threaten food production; and considerations for food safety as a primary element of food security in both developed and developing countries. The role of informatics in addressing private sector and public policy decision-making challenges to food security from the impacts of climate change is discussed. The emphasis is on how informatics can be used to better manage agricultural and natural resources for sustainable food production and to assure food security for the future.
- KonferenzbeitragAn OGC Web Processing Service for assessing the quality of solar radiation measurements(Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Espinar, Bella; Gschwind, Benoit; Wald, Lucien; Thomas, ClaireA service is presented that assesses the quality of measurements of daily global irradiation or means of global irradiance acquired by a ground station. Measurements are checked against models resulting in a measure of plausibility. This on-line service obeys the WPS (Web Processing Service) standard of the Open Geospatial Consortium. It is free of use and can be integrated into routine operations and Web portals thanks due its interoperability capability.

- KonferenzbeitragA Common Reference Model for Environmental Science Research Infrastructures(Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Chen, Yin; Martin, Paul; Magagna, Barbara; Schentz, Herbert; Zhao, Zhiming; Hardisty, Alex; Preece, Alun; Atkinson, Malcolm; Huber, Robert; Legré, YannickIndependent development of research infrastructures leads to unnecessary replication of technologies and solutions whilst the lack of standard definitions makes it difficult to relate experiences in one infrastructure with those of ot hers. The ENVRI Reference Model, www.envri.eu/rm, uses the Open Distributed Processing standard framework in order to model the "archetypical" environmental research infrastructure. The use of the ENVRI -RM to illustrate common characteristics of European ESFRI environmental infrastructures from a number of different perspectives provides a common language for and understanding of environmental research infrastructures, promote technology and solution sharing between infrastructures, and improve interoperability between implemented services .
- KonferenzbeitragChallenges of Electricity Production Scenarios Modelling for Life Cycle Assessment of Environmental Impacts(Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Blanc, Isabelle; Beloin-Saint-Pierre, DidierThis communication presents a first attempt at making a life cycle assessment of prospective electricity production scenarios which were designed in the EnerGEO project. We start by a basic review of system (in this case, scenario) modelling expectations in today s LCA study. We then review some of the challenges of implementation due to the lack of detailed description of present and future electricity production systems. The importance of a detailed description is then shown with an evaluation of uncertainty of life cycle impact assessment results for three scenarios of German electricity production in 2030. The significant uncertainties we found, prevent us from detecting a relevant trend or making any comparison between the three chosen scenarios. We finally come to the conclusion that the LCA methodology will become relevant for the environmental assessment of electricity production scenarios when many more detailed information are accounted to describe future technologies, structures and sources of energy.
- KonferenzbeitragEnvironmental Footprinting in the IT-for-Green Project – A CEMIS Use Case(Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Solsbach, Andreas; Rapp, Barbara; Teuteberg, Frank; Gräuler, Matthias; Stiel, Florian; Renatus, Fabian; Vornberger, JanThis paper presents functionality and design elements of a Corporate Environmental Management Information System (CEMIS) in the project IT-for-Green: Next Generation CEMIS for Environmental, Energy and Resource Management . The CEMIS under development in the IT-for-Green project uses a service-oriented architecture whose functionality will be demonstrated by means of a use case. Despite the theoretical development of CEMIS for as long as 20 years, CEMISs are not commonly used by companies. There is a substantial gap between the research and the use of CEMISs in companies, which the paper at hand aims to reduce by proposing a flexible and adoptable architecture to support companies in their current efforts. The developments in the case of company communication and the demands of stakeholders, especially in the field of corporate social responsibility (CSR) reporting, require handling. The development in the company communication and scientific community imply the extension of environmental to sustainability reporting which includes environmental, social and economic aspects. Current CEMIS are required to handle more and more business processes (as data source etc.) in the daily business of companies; the paper will indicate benefits of using an integrated CEMIS in the information technology (IT) landscape of a company. The paper will briefly introduce the IT-for-Green project and the software developed. The main focus is on a real world example the paper shows how our CEMIS can be used to assess the environmental impact of a product.
- KonferenzbeitragPotential and Problems of the Cellular System Approach for Environmental Modeling and Simulation(Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Wittmann, JochenBy the growing use of geographic information systems (GIS) the use of cellular approaches for modelling and simulation spatial and especially geographical processes and systems gains more and more importance. This paper gives an overview over the basic definitions and emphasizes a proper differentiation between the very tight definition of real cellular automata and the very universal one for cellular systems. On the base of these definitions typical problems are discussed, which raise for modelling spatial objects given by raster or vector data and by representing spatial relationships between these objects. Furthermore the difference in semantics between neighbourhood relation in GIS and neighbourhood relations needed for modelling purposes are elaborated.
- KonferenzbeitragA pre-market service to map biomass potentials on a regional level(Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Tum, Markus; Günther, KurtIn the framework of the EU FP7 project ENDORSE (Energy Downstream Services Providing energy components for GMES) a pre-market service is developed to estimate the annual above ground biomass increase for forests in Germany. This development is driven by the requirements of a prime user (Forest Competence Center Eberswalde) and done in close cooperation with experts in the field of forestry. One aim of the service is to develop a cost and time efficient method to deliver yearly estimates of above ground forest biomass increase using satellite measurements and modelling techniques as the BETHY/DLR SVAT model. Another aim is to use mainly satellite observations coming from GMES services and/or GMES space components. Our yearly estimates of above ground forest biomass increase covering the time span from 2000 to 2012 will fill the gaps of the national forest inventories. In Germany the first and second National Forest Inventory (NFI) took place in the years 1987 and 2002 while the third inventory was performed in 2011 and 2012. This large-scale ground mapping of the forest status and forest productivity uses random sampling of forest parameters for the entire territory of the Federal Republic of Germany. The new pre-market service allows monitoring forest growth on a regional level with 1km x 1km spatial resolution with respect to local meteorological conditions
- KonferenzbeitragPotenzialatlas Erneuerbare Energien Baden-Württemberg(Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Müller, ManfredDie baden-w rttembergische Landesregierung hat sich zur Umsetzung der Energiewende ambitionierte Ziele beim Ausbau Erneuerbarer Energien gesetzt. Neben den Ma nahmen zur Verbesserung der Energieeffizienz sind der naturvertr gliche Ausbau der Photovoltaik und der Windenergie dabei wichtige Bausteine. Als strategisches Informationsinstrument soll der von der LUBW Landesanstalt f r Umwelt, Messungen und Naturschutz erstellte Potenzialatlas Erneuerbare Energien den Bestand und das m gliche Potenzial f r die Umsetzung aufzeigen. Derzeit werden die Themen Solar-, Wind- und Wasserenergie in einem Internetangebot mit Karten und zugeh rigen statistischen Informationen dargestellt. Neben der Bilanzierung m glicher gemeindlicher Ausbaupotenziale werden auch anlagenbezogene Informationen dargestellt. So kann sich bspw. jeder Hausbesitzer ber Kosten und Nutzen der Errichtung einer Photovoltaik-Anlage informieren. Fachbeh rden, Planer, Investoren und andere Akteure erhalten n here Information zu Einschr nkungen f r die Windenergienutzung. Insgesamt zeigt der Atlas, dass die Rahmenbedingungen f r einen umweltvertr glichen Ausbau der Erneuerbaren Energien in Baden-W rttemberg gegeben sind. Das von der Landesregierung bis 2020 angestrebte Ziel, 10 Prozent des Strombedarfs aus heimischer Windkraft zu decken, ist auch bei einem naturvertr glichen Ausbau erreichbar. Als strategisches Werkzeug liefert der Potenzialatlas dazu in einer landesweiten bersicht und f r Gemeindegebiete vergleichbare Ergebnisse und Entscheidungshilfen. Er kann und soll aber nicht die ma nahmenbezogenen Prozesse auf der Ebene der Bauleitplanung oder der Regionalplanungsebene ersetzen.
