The design process for stiffened lightweight structures faces many challenges. Current design goals, especially in the aircraft industry, demand significant decrease in structural weight while keeping development and manufacturing costs low. Therefore, more complex design choices are investigated and show promising potential. The resulting increase in computational effort presents a remaining challenge. A novel approach for the design of stiffened lightweight structures, that enables strategic application of individualization and therefore allocates computational effort to areas of a structure where high benefits can be expected, is presented. Starting from a structure with common parts, the concept of individualization, i.e. adapting the design to local loads, is applied iteratively to selected parts of the structure. The methodology of strategic individualization is explained in detail before being applied to an example structure. This application shows the general capability of the methodology to design lightweight structures with less computational effort compared to a conventional approach.
