The use of Surrogate Based Optimization (SBO) is widely spread in engineering design to reduce the number of computational expensive simulations. However, “real-world” problems often consist of multiple, conflicting objectives leading to a set of competitive solutions (the Pareto front). The objectives are often aggregated into a single cost function to reduce the computational cost, though a b...

Multiple watermarks is to convey multiple sets of information, proposed to suit similar or differing objectives and also used to increase robustness with many different methods. This paper elaborates suitability of different transform based multiple watermarking techniques such as successive, segmented and composite watermarking. It also provides a comprehensive review of the existing literatur...

Abstract Blade envelopes offer a set of data-driven tolerance guidelines for manufactured components based on aerodynamic analysis. In Part I this two-part paper, workflow the formulation blade is described and demonstrated. II, extended to accommodate multiple objectives. This allows engineers prescribe manufacturing that take into account performance criteria. The quality can be correlated wi...
