A Robust Concept Exploration Method for Configuring Engines

9612365 Mistree本奖项提供资金，用于研究和实施一种确定定制和定制系统(如飞机、船舶和飞机发动机)的初始顶层规格的方法。该方法将侧重于划定满足设计目标但在设计中保留自由的设计配置区域，直到获得足够的信息来挑选单个配置进行进一步设计定义。研究方法将把现有的分析工具和健壮的设计原则结合起来，通常只在后期设计阶段实施，并将它们纳入产品实现时间表的早期阶段。这些工具的有效应用将通过综合和实施实验和统计技术(实验设计、方差分析和响应面方法)和稳健设计技术来实现。如果成功，这项研究的结果将使设计师能够探索和确定许多替代设计配置，并随后将重点放在单一配置上，以便进一步分析和描绘。由此产生的方法应该有助于与以下相关的成本效益研究：(1)综合设计(从多学科、系统的角度进行设计)，(2)稳健设计(对产品实现时间线上的变化相对不敏感的设计)，(3)灵活设计(允许以低成本审查相对较小的变化)，(4)可修改设计(允许以成本效益的方式调整设计以适应总体需求的大变化)。在产品实现时间线的早期阶段进行此类研究的能力对美国工业的商业和国防部门都应该是有价值的。

9612365 Mistree This award provides funding for the research on and implementation of a method for determining initial, top-level specifications of designed-to-order and made-to-order systems such as aircraft, ships, and aircraft engines. The approach will focus on the delineation of regions of design configurations that satisfy design goals but that retain freedom in the design until sufficient information is obtained to pick a single configuration for further design definition. The research approach will bring together existing analysis tools and robust design principles, generally implemented only in later design stages, and incorporate them in the early stages of a product realization time line. Effective application of these tools will be achieved through the integration and implementation of experimental and statistical techniques (design of experiments, analysis of variance, and response surface methodology) and robust design techniques. If successful, the results of this research will enable designers to explore and identify many alternative design configurations and subsequently focus on a single configuration for further analysis and delineation. The resulting method should facilitate cost-effective studies associated with (1) comprehensive design (design from a multidisciplinary, systems perspective), (2) robust design (designs that are relatively insensitive to changes along a product realization time line), (3) flexible design (allow relatively small changes to be examined inexpensively), (4) modifiable design (allow designs to be adapted to large changes in overall requirements cost-effectively). The capability to perform such studies in the early stages of a product realization time line should be of value to both the commercial and defense sectors of US industry.
