Zusammenfassung
Material flow analysis deals with gathering,
harmonizing, and analyzing data about physical flows and
stocks from different sources with varying quality in order to
quantify the material turnover of a defined system. As data
availability and quality is limited, there is uncertainty that the
available data represent the actual value of interest. In the
present study this degree of belief is expressed via fuzzy sets,
which specify the possible range of values of the input data.
The input data are forced to comply with the mass balance
constraints given by the material flow model. As a result, possible
ranges are calculated for each flow and consistency levels are
determined to identify flows which are in good agreement with
the model and flows which are hardly consistent. The method is
illustrated using a sub-system of the Austrian wood flow model
as a case study.
