Ship Assembly

This paper proposes a novel methodology for the optimal design of fixture layouts in ship assembly processes, using a combination of the direct stiffness method and simulated annealing to minimize dimensional gaps and improve welding quality.

This paper develops a nonlinear variation model (NVM) to account for geometric nonlinearity, welding shrinkage, and angular distortion in the assembly of compliant metal plates, with calibration using a composite Gaussian process (CGP) to enhance prediction accuracy.
