Based on: — a rapid design-oriented finite element method for analysis of large complex thin-walled steel structures such as ship hulls, — a comprehensive mathematical model for the evaluation of the capability of such structures, and — analytical expressions for the derivatives of the response and the capability with respect to the governing design variables, the paper presents a procedure for minimizing a linear combination of structural weight and production costs for a number of loading conditions. The large, highly constrained non-linear optimization problem is solved by sequential linear programming.
