Metamodels aim to approximate characteristics of functions or systems from the knowledge
extracted on only a finite number of samples. In recent years kriging has emerged as a …

Metamodeling is becoming a rather popular means to approximate the expensive
simulations in today's complex engineering design problems since accurate metamodels …

The use of metamodeling techniques in the design and analysis of computer experiments
has progressed remarkably in the past 25 years, but how far has the field really come? This …

Computation-intensive design problems are becoming increasingly common in
manufacturing industries. The computation burden is often caused by expensive analysis …

Any device aiming to harness the abundant clean and renewable energy from ocean and
other water resources must have high energy density, be unobtrusive, have low …

This contribution summarizes the design and analysis of experiments with computerized
simulation models. It focuses on two metamodel (surrogate, emulator) types, namely first …

The integration of optimization methodologies with computational analyses/simulations has
a profound impact on the product design. Such integration, however, faces multiple …

The use of kriging models for approximation and metamodel-based design and optimization
has been steadily on the rise in the past decade. The widespread use of kriging models …

Engineering optimization problems usually involve computationally expensive simulations
and many design variables. Solving such problems in an efficient manner is still a major …

Surrogate models are commonly used to replace expensive simulations of engineering
problems. Frequently, a single surrogate is chosen based on past experience. This …
