...Abstract Abstract Surrogate models are used as a substitute for sophisticated system analysis in engineering design in order to improve efficiency, enhance understanding of problem domains and facilitate multidisciplinary design trade-offs. However, the cost of acquiring knowledge...

... expensive to evaluate and difficult to run, in large part due to the imprecise knowledge available at the beginning of the design process. To circumvent these problems, a common approach proposed in the literature is the use of surrogate models. In this paper, we propose a framework for building surrogate...

... 18 06 2008 This paper deals with the development of simulation-based design models under uncertainty, and presents an approach for building surrogate models and validating them for their efficacy and relevance from a design decision perspective. Specifically, this work addresses...

... 09 06 2008 In order to reduce the time and resources devoted to design-space exploration during simulation-based design and optimization, the use of surrogate models, or metamodels, has been proposed in the literature. Key to the success of metamodeling efforts are the experimental...
