In the paper basicconcepts of mew methodology of fuzzy boundary element method are presented. This article deals with fuzzy-set-valued mappings which are solutions of the fuzzy boundary integral equations. Extact fuzzy solutions of the fuzzy boundary integral equations are defined as well as conditional solutions. Computational fuzzy problems and applications are considered in details for boundary potential problems with fuzzy Dirichlet and Neumann type boundary conditions and fuzzy density source functions in a fuzzy domain.

W pracy przedstawiono elementy nowej koncepcji metody rozmytych elementów brzegowych. Artykuł omawia odwzorowania o wartościach rozmytych, które są rozwiązaniami rozmytych brzegowych równań całkowych. Analiza przeprowadzona jest na przykładzie problemu brzegowego klasycznej teorii potencjału z uwzględnieniem rozmytych warunków brzegowych typu Dirichleta i Newmanna, rozmytej funkcji gęstości źródeł oraz rozmytego kształtu obszaru.
