A new design problem is developed to find a layout for fuselage stiffeners (rings and stringers) such that the structural mass, compliance, and the first-mode natural frequency can be optimised, subject to structural constraints. The stiffeners are modelled as beam elements. Three multiobjective meta-heuristics are employed to solve the problem, and a comparative study of the results of these optimisers is carried out. It is found that the proposed layout synthesis problem for aircraft fuselage stiffeners leads to a set of efficient structural solutions, which can be used at the decision-making stage. It is an automated design strategy with high potential for further investigation.eninfo:eu-repo/semantics/closedAccessEngineeringTransportationAircraft fuselageMultiobjective optimisationRings and stringersFuselage stiffenersMeta-heuristicsEvolutionary algorithmsStructural optimisationConstrained optimisationAerodynamicFinite element analysisTopology optimizationDifferential evolutionConceptual designAlgorithmsPerformanceAircraftDecision makingDesignEvolutionary algorithmsOptimizationAutomated designComparative studiesEvolutionary optimisationLayout synthesisMulti-objective meta-heuristicsMultiobjective evolutionary optimisationStructural constraintsStructural solutionsFuselagesArticle0005764003000052-s2.0-85092268889162175802-4Engineering, mechanicalTransportation science & technologyStacking Sequence (Composite Materials); Rigidity; Buckling
