Research performed under this grant will develop methods to rapidly assess early engineering designs. To assess many designs using conventional approaches requires a significant and often economically infeasible amount of computation. The approach to rapid assessment of early designs to be researched under this grant utilizes set-based representations of early design descriptions thereby permitting approximate assessment of the performance of regions or sets of the design space. This work will extend initial results to efficient mapping of sets in high dimensional design spaces, and to design problems with realistic mappings (nonmonotonic performance evaluation functions). The results of this research will permit engineering designers to rapidly and inexpensively determine the approximate region of performance that a candidate set of designs will exhibit. Set-based design can increase concurrency by permitting information to be passed to downstream or parallel groups as sets of possible designs. These results will permit designers to exchange imprecise, partially complete, design information to accelerate the design process and shorten the engineering design cycle.

根据这项赠款进行的研究将开发快速评估早期工程设计的方法。 使用传统的方法来评估许多设计需要大量的计算，并且通常在经济上是不可行的。 根据该补助金进行研究的早期设计的快速评估方法利用早期设计描述的基于集合的表示，从而允许对设计空间的区域或集合的性能进行近似评估。 这项工作将扩展到有效的高维设计空间中的集映射的初步结果，并设计问题与现实的映射（非单调性能评价函数）。 这项研究的结果将允许工程设计人员快速和廉价地确定一组候选设计将展示的性能的近似区域。 基于集合的设计可以通过允许信息作为可能的设计集合传递到下游或并行组来增加并发性。 这些结果将允许设计人员交换不精确的，部分完整的设计信息，以加快设计过程，缩短工程设计周期。
