The Design Axiom, consisting of Independence Axiom & Information Axiom, is applied to marine design problems. The Independence Axiom helps generate design alternatives by considering functions and structures, while the Information Axiom aids in selecting the best solution with the least information. In thruster design, the Independence Axiom effectively relates functional requirements to design parameters. The Information Axiom helps choose the best main engine solution with minimal information. For Barge design, the Design Axiom proves effective in selecting design variables. However, larger system designs like ships may pose challenges due to unclear requirements in the early stages.
