2009 International Conference on Aerospace Sciences and Aviation Technology  
The role of optimization in various practical applications has been increasing over the years. In the field of aerodynamics, design optimization is rapidly evolving in many ways. One of the latest developments in this field is the introduction of surrogates or metamodels. The use of surrogates has a number of advantages especially concerning the computation cost, memory and time budgets. The present paper aims to introduce the topic of surrogate-based optimization. An overview on the main

The paper is finalized with some general recommendations. This paper is devoted to the following: -illustrating the concept of surrogates, their types, and construction, and -surveying the related previous efforts in the field. The remainder of this paper is organized as follows: in the next section, the main elements of surrogate modeling are discussed. Next, the main types of surrogates are discussed and compared. A closely related topic which is the design of experiment (DoE) is then discussed. A survey over the efforts contributing in this field is presented near the end of the paper and the paper finalizes with the main conclusions and general recommendations. All abbreviations mentioned throughout the paper are listed in the appendix.
