The Design Axioms by N. P. Suh help in marine design by considering functions and physical products. The Independence Axiom helps generate design options, while the Information Axiom aids in selecting the best solution. In ship design, uncertainty often leads to a probabilistic approach. The Axioms are useful in thruster and main engine selection, but structural design poses challenges due to many design parameters. A generalized approach is needed for structural design, as shown in a barge design example.
