“…The most widely used is a genetic algorithm (GA), an 18-panel horseshoes design problem was first proposed in [4], with a commercial software DARWIN used for optimization. After that, many researchers used improved GA [5,6] and modified GA [7][8][9][10][11] to solve this problem. The main concern of these studies is the efficiency of the algorithm and a blending requirement.…”

“…The main concern of these studies is the efficiency of the algorithm and a blending requirement. Hence, specific techniques were developed to address the blending problem, such as: guide-based design [6], inward and outward blending [6,8,10], generalized blending [7], a ply drop sequence (PDS) [9], a blending constraint can be imposed by modifying a chromosome implemented in the GA [11] to improve efficiency. Further, the GA was also applied to a wing-box design problem [12][13][14].…”

Additional Information:• This paper was accepted for publication in the journal Compos- b s t r a c tA novel framework to design tapered composite structures is proposed for buckling analysis with multiple manufacturing constraints, with variables dealt with separately at different levels and manufacturing constraints divided and imposed in each step. The framework is based on two techniques -a sequential permutation table (SPT) method and a global shared-layer blending (GSLB) method; a design concept is extending from an individual panel to the overall structure by improving its blending property. A problem to design an 18-panel tapered composite structure is adopted to study and validate the proposed framework; a detailed design process is executed step by step to demonstrate the improvements of blending property. Multiple manufacturing constraints are analyzed for the obtained optimal solution, which is also compared with previous studies. The high efficiency of the proposed framework implies its potential for design of large-scale composite structures with complex manufacturing constraints.
