Reliability-Based Design of an Aircraft Wing Using a Fuzzy-Based Metaheuristic

The purpose of this paper is to design aircraft wing using reliability-based optimization concerned fuzzy uncertainty variables. A possibilistic safety index-based (PSIBDO) with uncertainties proposed overcome difficult tasks from the original probabilistic problem. problem minimize mass a composite subject aeroelastic and structural constraints through consideration material properties are uncertainties. variables include structure dimensions. approach needed alleviate such Due complexity structures analysis, nonprobability-based an alternative choice increase computational efficiency in process. optimum results show our approach.
