Rapid Assessment of Early Designs: RAED

在这项资助下进行的研究将开发快速评估早期工程设计的方法。使用传统方法评估许多设计需要大量且通常在经济上不可行的计算量。在这项资助下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。这项工作将把最初的结果扩展到高维设计空间中集合的有效映射，以及具有现实映射（非单调性能评估函数）的设计问题。这项研究的结果将使工程设计人员能够快速而廉价地确定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将信息作为可能的设计集传递给下游或并行组来提高并发性。这些结果将允许设计师交换不精确的，部分完整的设计信息，以加速设计过程并缩短工程设计周期。

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.
