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.

该工程研究启动（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包括对制造过程的考虑，可以做出有效的决策来自定义材料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着重于在整体系统中依次探索基于模型的材料和产品的关系，而不是同时实现产品，材料和制造的同时实现。该项目中设想的整体，基于系统的，强大的共同设计方法将解释涉及产品和不确定性下的制造过程的多层次材料系统之间的目标和相互作用。该方法将使设计师能够同时可视化和探索特定水平的目标，多层次交互和差异分析，从而使数字设计中的定量链接能够与材料结构到制造业工作流程。该项目将通过战略性地整合系统工程，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，从而使对产品，材料和制造过程之间的耦合有基本的了解。此外，通过设计新的课程，该课程嵌入了ICME主题设计并在相关工具上组织一所暑期学校，学生和从业人员将为您准备好从系统角度来解决复杂的材料设计挑战。本ERI项目将建立基础技术，以耦合多层建模材料材料材料材料，产品，其制造商和其制造商的策略设计。研究计划由两个部分组成：（1）建立依赖历史的，数据驱动的处理结构 - 绩效性能（PSPP）链接； （2）通过管理不确定性及其传播来探索跨多个级别的范围的范围稳健解决方案集的基于系统的反共同设计框架。总体预期结果是一个新型的基于系统的多级框架，可根据不确定性在不确定的分布式利益相关者做出的强大决策方面对材料，产品和制造过程的反相反共同设计。智力优点包括：（1）对多层次材料，制造过程和产品设计决策的相互依赖性质的基本理解； （2）材料结构层次结构实现产品的有效数学表示； （3）在设计的早期阶段，用于多级强大的共同设计可视化和探索不同工程学科（设计，材料和制造）之间相互作用的计算框架。计划将四项相关的教育和外展活动与更广泛的学生和专业人士组成：（1）通过将结果整合到现有研究生课程中，使数据驱动的PSPP链接建模程序正式化； （2）通过ICME课程的新设计迭代，更新和传播针对标准ICME问题的基于系统的设计方法； （3）组织一周与ICME设计相关的工具进行为期一周的在线暑期学校； （4）通过科学出版物，演讲和研究专着大致传播结果。这些活动将导致新的经过验证和验证的技术来教授ICME的设计；新的测试示例以迭代，评估和建立结构的通用效用（单独和集成）；这是为ICME工作流中注入多层次材料建模，制造考虑和基于决策的设计策略的基础。该奖项反映了NSF的法定任务，并且使用基金会的知识分子优点和更广泛的影响审查标准，认为值得通过评估值得支持。
