The focus of this thesis is to introduce a proof-of-concept illustrating the integration of cost and performance as primary design drivers for structural design. Of particular interest to the
aerospace industry is laminated structural design, therefore an example problem of a laminated plate structure is selected. This
problem presents two primary challenges: linking cost in as general a way as possible to the design variables, and dealing with the many discrete design options available in a laminated plate. The first issue is examined by using a theoretical cost model for advanced composite fabrication and using a Direct Operating Cost model. The second issue is addressed using a gradient based optimization algorithm and a Discrete Material Optimization (DMO) method, which
is typically used in topology optimization of structures.
