    Attribute-based data quality evaluation in regional Material Flow Analysis
    (EnviroInfo & ICT4S, Adjunct Proceedings, 2015) Schwab, Oliver; Laner, David; Rechberger, Helmut
    A method for data quality evaluation in macro scale MFAs such as national resource budgets is presented. MFA data is never totally accurate but may have certain defects. The four information defects semantic, representativeness, provenance and context are introduced. These information defects are considered to be functions of data attributes. Data attributes are assigned to MFA data according to an existing framework. A method for quantification of information defects and for expressing the data quality of a flow by a single number is presented. It provides opportunities for understanding and evaluating resource budgets, their a priori information basis and their information content.

    Material Flow Analysis with Software STAN
    (Environmental Informatics and Industrial Ecology, 2008) Cencic, Oliver; Rechberger, Helmut
    STAN (short for subSTance flow ANalysis) is a free software that supports performing material flow analysis (MFA) according to the Austrian standard ÖNORM S 2096 (Material flow analysis Application in waste management) under consideration of data uncertainties. The main idea behind STAN is the combination of all necessary features of a MFA in one software product: graphical modelling, data management, calculations and graphical presentation of the results. The benefits of the application of STAN are demonstrated on the example of a fictitious waste management company.
