    Multiple criteria decision support by evolutionary computation
    (Sustainability in the Information Society, 2001) Laumanns, Marco; Zitzler, Eckart; Thiele, Lothar
    This paper describes the use of Evolutionary Algorithms (EAs) as a decision support tool in environmentally relevant decision problems. Though various methods from Artificial Intelligence as well as from Computational Intelligence have been successfully integrated into Environmental Decision Support Systems (EDSS), the use of Evolutionary Computation has so far remained marginal in this context. On the other hand EAs are popular in solving large-scale optimization problems in diverse engineering disciplines, where complex, non-linear models make the use of traditional optimization techniques difficult or impossible. In addition, they can handle multiple criteria simultaneously, being able to generate efficient solutions even for problems where the number of alternatives is very large or only implicitly defined, which makes them a promising tool in environmental decision making.

    Systemdynamische Analyse von Kreislaufwirtschaftssystemen — Ökonomische und ökologische Untersuchung am Beispiel der Altauto- Verwertung mittels des System Dynamics-Ansatzes
    (Sustainability in the Information Society, 2001) Lander, Sandra; Fleischer, Günter
    Recycling management systems are becoming more important in the Sustainable Development of national economies. Governments substantiate this with different legal regulations, e.g. regulations concerning packing of consumer goods, batteries, end-of-lifevehicles. To analyse such systems, both economically and ecologically, operational tool s like `Life Cycle Assessment', `Cost-Benefit Analysis' are generally used. However, recycling management systems are subject to change and in order to avoid trial-and-errorprocesses the operational tools have to be supplemented by strategic ones. This contribution introduces a strategic tool for recycling management systems based on system dynamics. The applicability of the tool is verified by an end-of-life-vehicle simulation model, which describes the end-of-life-vehicle process up to 2020.

    Modeling the Environmental Impacts of E-commerce using SmartCost: Some initial results
    (Sustainability in the Information Society, 2001) Sui, Daniel Z.; Phillips, Don T.
    This paper reports the initial findings of an on-going interdisciplinary project funded by the U.S. National Science Foundation (NSF). The project expands conventional industrial ecology with the goal of making a ground-breaking development in information ecology a new conceptual and analytical framework that can be operationalized in practice to systematically examine the environmental impacts of the emerging digital economy. We want to unpack the paradoxical relationship between the digital economy and the environment by addressing three key questions: 1. To what extent and under what circumstances, is the electronic delivery of goods and services going to substitute, complement, or synergistically integrated with traditional ways of doing business? 2. What are the environmental consequences, measured in terms of energy/material consumption and waste production, of using the Internet to deliver information-based products and services? 3. What are the environmental consequences, measured in terms of energy/material consumption and waste production, of using the Internet to facilitate the retailing of tangible goods and products? By extending previous works in industrial ecology, this project develops an informational ecology approach as the guiding analytic framework that incorporates both production and consumption elements in the new economy. Our information ecology approach aims to establish links between industrial metabolism and information processing. Using the analytical framework embedded in SmartCostTMdeveloped at Texas A&M, detailed life-cycle analysis (LCA) of electronic commerce are being conducted at the company level for Internet-based businesses.

    Einheitliche Zugriffsmethoden in einer heterogenen Systemlandschaft
    (Sustainability in the Information Society, 2001) Iden, Frank
    FIS-Broker is a keypart of the Urban and Environmental Information System of the Berlin Ministry for Urban Development. Through an easy to handle uniform browser-tool the FIS-Broker makes data available, which were previously only available in specialised informationsystems. To access these data, the user requires no knowledge of the hard- or software. The data remain unchanged at source. Access is facilitated via the FIS-Broker's metainformationsystem. FIS-Broker will assist the user in finding, visualising and providing information. It's spatial relation service will allow for the combining of heterogeneous databases . The components of the FIS-Broker can also be used directly in any module of the entire specific information systems.

    Energy analysis of e-commerce and conventional retail distribution of books in Japan
    (Sustainability in the Information Society, 2001) Williams, Eric; Tagami, Takashi
    Energy use associated with distribution via e-commerce and conventional retail is compared for book sales in Japan. The simulation of energy consumption includes the following factors: fossil fuel used by trucks in distribution from distributor to bookstore or e-commerce firm, transpo rt fuel used by the consumer or courier service production of packaging, and energy for appliances and climate control at the point of sale (home or bookstore). Results indicate a crossover in environmental performance according to population density. Conventional retail uses less energy than e-commerce in dense urban areas, mainly due to avoided packaging, but can consume more in suburban and rural areas due to the inefficiency of personal automobile transpo rt.

    Verwaltung von umweltmanagementbezogenen Wissensinhalten mit dem EcoExplorer System
    (Sustainability in the Information Society, 2001) Arndt, Hans-Knud; Günther, Oliver; Holger, Pluskat
    Efficient and effective environmental management requires the integration of a broad variety of existing knowledge assets (analysis, best practices, lesson learned) and their documentation. An environmental knowledge object within the meaning of an environmental knowledge management consists of content (data and information) and context (a perspective that gives meaning to the content). One of the main challenges of (environmental) knowledge management is to relate content and context . The data element catalogue is an adequate method for environmental knowledge discovery and mapping. The today implementation of our knowledge management system, the EcoExplorer System, supports the discovery and mapping of environmental knowledge objects.

    Entwurf einer Theorie umweltbezogener Metadatenverarbeitung
    (Sustainability in the Information Society, 2001) Müller, Markus
    Management of metainformation is one of the central subjects of environmental information science. However, the widely used definition of metadata as data about data is scientifically no satisfying. The use of common concepts to describe environmental metadata and metainformation would also be advantageous in the actual practical usage and implementation of metadata and metainformation systems. Basis of the herein outlined theory is semiotics, the science of signs.

    IeMAX. Das fuzzy logic-gestützte Umweltbewertungssystem
    (Sustainability in the Information Society, 2001) Herzog, Christof
    The modelling system IeMAX (Instrument for Integrated environmental Modelling and Assessment with Fuzzy Logic Expert Systems) connect partial theories and methodological approaches for an integrated assessment of conflicting landuse pattern. It aims at transfering basic environmental research to practical applications, thus providing valuable theorybased generalised insights into sustainable development as a fundamental topic of environmental research. Two experiments explain how IeMAX works and focus on the three main components: 1. analysing, 2. modelling and 3. assessment of interdisciplinary uncertain knowledge. Furthermore special features and pratical application fields of IeMAX are shown.
