Research results from University of Stuttgart update understanding of fuzzy science

  2008 JUN 16 - (VerticalNews.com) -- According to a study from Stuttgart, Germany, "In this paper, a new uncertainty analysis for the transformation method (TM) is proposed. As a practical implementation of fuzzy arithmetic, the TM is a convenient tool for the simulation and analysis of systems with uncertain parameters that are expressed by fuzzy numbers."

  "The proposed uncertainty analysis and the sensitivity analysis of the TM complete each other in providing some quantification of the relationship between the uncertainties of the system input and the system output. The computation of gain factors is proposed, which allows the estimation of the absolute and relative measures of uncertainty," wrote U. Gauger and colleagues, University of Stuttgart.

  The researchers concluded: "These measures allow the quantification of the influence of the uncertainty of the input on the uncertainty of the output."

  Gauger and colleagues published their study in Fuzzy Sets and Systems (A new uncertainty analysis for the transformation method. Fuzzy Sets and Systems, 2008;159(11):1273-1291).
