The research objective of this Engineering Research Initiation (ERI) project is to investigate new ways to co-consider manufacturing processes in the early stages of materials and product design. By including the considerations of manufacturing processes in the early stages of design, designers can make effective decisions to customize material microstructures and achieve desired product performance, as envisioned by Integrated Computational Materials Engineering (ICME). Current materials design methods focus on sequentially exploring model-based relations of materials and products at individual levels instead of a concurrent realization of products, materials, and manufacturing within a holistic system. The holistic, systems-based, robust co-design approach envisioned in this project will account for the goals of and interactions between multilevel material systems involving the product and the manufacturing processes under uncertainty. The approach will enable designers to concurrently visualize and explore level-specific objectives, multilevel interactions, and sublevel analyses, thus enabling quantitative linkages in digital design to materials structure to manufacturing workflows. The project will promote the progress of science by strategically integrating knowledge and techniques from the fields of systems engineering, engineering design, and materials science to enable a fundamental understanding of the couplings between products, materials, and manufacturing processes. Additionally, by designing new curricula that embed Design for ICME topics and organizing a summer school on the associated tools, students and practitioners will be better prepared to address complex materials design challenges from a systems perspective.This ERI project will establish foundational techniques for coupling multilevel modeling of hierarchically structured materials, products, and their manufacturing processes with multiobjective systems design strategies and uncertainty management. The research plan consists of two parts: (1) establish history-dependent, data-driven processing-structure-property-performance (PSPP) linkages; and (2) formulate a systems-based inverse co-design framework for exploring ranged sets of robust solutions across multiple levels by managing uncertainty and its propagation. The overall expected outcome is a novel systems-based multilevel framework for the inverse co-design of materials, products, and manufacturing processes in terms of robust decisions made by distributed stakeholders under uncertainty. The intellectual merit includes: (1) a fundamental understanding of the interdependent nature of multilevel materials, manufacturing processes, and product design decisions; (2) an efficient mathematical representation of material structure hierarchy to realize products; and (3) a computational framework for the multilevel robust co-design visualization and exploration of the interactions between the different engineering disciplines (design, material, and manufacturing) in the early stages of design. Four related educational and outreach activities are planned to integrate the research with the broader community of students and professionals: (1) formalize the data-driven PSPP linkage modeling procedure by integrating the results in existing graduate courses; (2) iterate, update, and disseminate a systems-based design approach for standard ICME problems through a new Design for ICME course; (3) organize a one-week online summer school on tools relevant to Design for ICME; and (4) broadly disseminate results through scientific publications, presentations, and research monographs. These activities will lead to new verified and validated techniques to teach Design for ICME; new test examples to iterate, assess, and establish the generic utility of the constructs (individually and integrated); and a foundation for infusing multilevel materials modeling, manufacturing considerations, and decision-based design strategies into ICME workflows.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

本工程研究启动（ERI）项目的研究目标是研究在材料和产品设计的早期阶段共同考虑制造过程的新方法。通过在设计的早期阶段考虑制造工艺，设计人员可以做出有效的决策，以定制材料的微观结构，并实现所需的产品性能，如集成计算材料工程（ICME）所设想的那样。当前的材料设计方法集中于在单个层次上顺序地探索材料和产品的基于模型的关系，而不是在整体系统内并行地实现产品、材料和制造。在这个项目中设想的整体的，基于系统的，强大的协同设计方法将占的目标和多级材料系统之间的相互作用，涉及产品和制造过程的不确定性。该方法将使设计师能够同时可视化和探索特定级别的目标，多层次的交互和子层次的分析，从而实现数字设计到材料结构到制造工作流程的定量联系。该项目将通过战略性地整合来自系统工程、工程设计和材料科学领域的知识和技术来促进科学的进步，从而从根本上理解产品、材料和制造过程之间的耦合。此外，通过设计嵌入ICME主题设计的新课程并组织相关工具的暑期学校，学生和从业者将更好地准备从系统的角度应对复杂的材料设计挑战。该ERI项目将建立耦合的基础技术分层结构材料、产品、和他们的制造过程与多目标系统设计策略和不确定性管理。该研究计划包括两个部分：（1）建立历史依赖的，数据驱动的加工-结构-属性-性能（PSPP）链接;（2）制定一个基于系统的逆向协同设计框架，通过管理不确定性及其传播，探索多个层次的鲁棒解决方案的范围集。总体预期的结果是一种新的基于系统的多级框架的逆向协同设计的材料，产品和制造过程中的鲁棒性决策的分布式利益相关者在不确定性。智力上的优点包括：（1）对多级材料、制造过程和产品设计决策的相互依赖性的基本理解;（2）实现产品的材料结构层次的有效数学表示;以及（3）用于多层次鲁棒协同设计可视化和不同工程学科之间交互的探索的计算框架（设计、材料和制造）在设计的早期阶段。四个相关的教育和推广活动，计划将研究与更广泛的学生和专业人士的社区：（1）通过整合现有的研究生课程的结果，正式的数据驱动的PSPP链接建模程序;（2）通过一个新的设计ICME课程，验证，更新和传播基于系统的设计方法的标准ICME问题;（3）组织为期一周的在线暑期学校，介绍与ICME设计相关的工具;（4）通过科学出版物，演讲和研究专著广泛传播成果。这些活动将产生新的经过验证和确认的技术来教授ICME设计;新的测试示例来验证、评估和建立结构的通用实用性（单独和综合）;和基础注入多级材料建模，制造考虑，决定-该奖项反映了NSF的法定使命，并被认为值得通过使用基金会的学术价值和更广泛的影响审查标准。
