Niezawodność konstrukcji w warunkach niepewności w ujęciu teorii zbiorów rozmytych

Ewa Szeliga

Abstract

Basic concepts of the fuzzy sets theory and reliability theory were desribed. Two kinds of uncertainty: randomness and unprecision were proposed to be taken under consideration in structural reliability assesment. Experts` edtimations were assumed to be described with the aim of fuzzy numbers. The concept of limit state function with fuzzy parameters was introduced. In effect structural reliability was concerned as a fuzzy event. Fuzzy measures of reliability and methods of their estimation were proposed. These measures were proposed to be applied for partial factors of safety calibration.
