This Faculty Early Career Development (CAREER) Program grant supports an integrated research and education project on modeling; analysis and control of dimensional variation in complex multistage assembly processes (MAP) with compliant parts such as in automotive, aerospace, appliance and electronics industries. The goal is to develop a generic MAP model with capabilities to represent key product and process control characteristics/features (KPC/KCC) with varying resolution/"information granularity" that can be utilized during design, launch and full production phases of a new manufacturing system. The model will be based on a generic Computer-Aided Design and Manufacturing (CAD/CAM) system integrated with statistical analysis to predict manufacturing process performance in early design phase. A challenge facing the proposed plan is the diversity of required information and lack of physical and geometrical relations between KCC and KPC. The research will focus on developing: (1) variation propagation models integrating statistical and CAD/CAM information; (2) multi-resolution/granularity of KPC/KCC as they change during product development; (3) computational efficiency for simulation of multistage assembly processes; and (4) generic issues pertaining to new process-oriented modeling, design and control. The education efforts are to: (1) integrate statistical analysis into CAD/CAM courses; (2) explore challenges in the development and realization of new MAP systems; and (3) provide opportunities in developing and analyzing MAP systems using 3D simulation tools. It also includes creating grade-specific (graduate, undergraduate and K-12) projects.Broader Impact: If successful, this project will lead to a new methodology that can: (1) Fundamentally integrate CAD/CAM models with statistical analysis to predict manufacturing process dimensional variability during design as it relates to compliant parts, thus continuously improving product quality while reducing overall new MAP development time through rapid fault root cause detection. (2) Facilitate math-based design and manufacturing of the MAP systems: The integration of product and process variables expands the classical "part interchangeability" concept into "process interchangeability" considered during early design phase of a new MAP development. This is critical in relation to suppliers selection, benchmarking or outsourcing. (3) Train Industrial Engineers in statistical methods and their application in CAD/CAM systems thus preparing them towards developing a new generation of CAD/CAM system for virtual realization of MAP.

学院早期职业发展(Career)计划资助一个综合性的研究和教育项目，该项目涉及汽车、航空航天、家电和电子行业中复杂的多阶段装配工艺(MAP)中的尺寸变化建模、分析和控制。目标是开发一个通用的地图模型，能够以不同的分辨率/“信息粒度”表示关键产品和过程控制特性/特征(KPC/KCC)，可在新制造系统的设计、启动和完整生产阶段使用。该模型将基于一个通用的计算机辅助设计和制造(CAD/CAM)系统，该系统与统计分析相结合，以预测早期设计阶段的制造过程性能。拟议计划面临的一个挑战是所需信息的多样性，以及科索沃保护团和科索沃保护团之间缺乏物理和几何关系。研究的重点是：(1)集成统计和CAD/CAM信息的变异传播模型；(2)KPC/KCC在产品开发过程中变化时的多分辨率/粒度；(3)多阶段装配过程模拟的计算效率；(4)与新的面向过程的建模、设计和控制有关的一般性问题。教育工作是：(1)将统计分析融入CAD/CAM课程；(2)探索开发和实现新地图系统的挑战；以及(3)提供利用三维模拟工具开发和分析地图系统的机会。它还包括创建特定级别(研究生、本科生和K-12)的项目。广泛的影响：如果成功，该项目将导致一种新的方法，该方法可以：(1)从根本上将CAD/CAM模型与统计分析相结合，在设计过程中预测制造过程的尺寸变异性，因为它与合规部件有关，从而通过快速故障根本原因检测来持续提高产品质量，同时减少整体新地图的开发时间。(2)促进基于数学的MAP系统的设计和制造：产品和工艺变量的集成将经典的“零件互换性”概念扩展为在新MAP开发的早期设计阶段考虑的“工艺互换性”。这在供应商选择、基准或外包方面至关重要。(3)对工业工程师进行统计方法及其在CAD/CAM系统中的应用培训，使他们为开发新一代地图虚拟实现的CAD/CAM系统做好准备。
