The algorithms presented on this portal - uncertainty quantifcation, fuzzy analysis and fuzzy stochastic analysis - have been implemented in a software solution. For the Fuzzy Analysis Framework and uncertainty quantification we offer a free license for non-commercial and educational use.

Analysis capabilities

Fuzzy Analysis is a multi-purpose framework for predicting system responses with respect to uncertainty of input parameters in a numerically efficient way. It can be combined with any arbitrary analysis software as linear/non-linear deterministic solution. The uncertainty of the input parameters is reflected completely in the fuzzy result, which
    • contains information about the variation of results
    • allows worst case studies
    • provides information about robustness and
    • sensitivity with respect to the input uncertainty

Technical information

The software solution is written entirely in Fortran and is available as linkable library file. The code runs
on Windows and Unix/Platforms platforms.
    The input file is organized in the human readable XML format. A GUI based application, that
      • creates input files in a graphical way and
      • supports the modeling of uncertain input parameters
      • allows a graphical examination of the uncertain results
      • and allows an additional robustness analysis
    is available for the Windows platform. The fuzzy structural analysis warps around the (external) deterministic solution. Bindings to the deterministic solution must be realized with a user written subroutine. Thus, an application of this library requires basic skills in Fortran.

    Free License

    A free educational license for the fuzzy analysis framework is available to qualifying institutions. Software developed and results obtained using the fuzzy analysis framework may only be distributed or used on a non-profit making basis.
