Abstract

Fuzzy sets theory has proven over the years to be a valuable tool for modeling uncertainty in engineering. It is used extensively in control, in expert systems and in rule-based models. However, applications to sensitivity analysis and regression are still few, mainly because there is no appropriate software available. A C++ library of objects has been developed to easily and efficiently introduce fuzzy sensitivity analysis into new or existing C/C++ code, and to perform multiple fuzzy linear regression. An outline of the library is given, together with examples of applications in hydrologic engineering. For problems involving only fuzzy regression, a more user-friendly interface is currently being developed. Introduction
