چکیده

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.

Reliability-Based Multidisciplinary Optimization for Aircraft Wing Design

Aircraft wing design typically involves multiple disciplines such as aerodynamics and structure. Multidisciplinary design optimization (MDO) has been recently used to deal with the multidisciplinary efforts in wing design. When reliability is considered, MDO for the wing design becomes much more computationally intensive. To improve the efficiency, the strategy of using Sequential Optimization ...

Aircraft Family Design Using Decomposition-Based Methods

This paper explores the use of decomposition-based methods for aircraft family design. The traditional approach in multidisciplinary design optimization is to decompose a problem along disciplinary lines. For aircraft family design problems, a more natural approach is decomposition by individual aircraft. This decomposition facilitates the concurrent development of several aircraft variants, pr...

Review: Metaheuristic Search-Based Fuzzy Clustering Algorithms

Fuzzy clustering is a famous unsupervised learning method used to collecting similar data elements within cluster according to some similarity measurement. But, clustering algorithms suffer from some drawbacks. Among the main weakness including, selecting the initial cluster centres and the appropriate clusters number is normally unknown. These weaknesses are considered the most challenging tas...
