建立基于系统的材料设计方法是实现材料和产品快速并行设计的重要一步，具有重大技术创新的潜力。材料设计涉及定制材料结构和加工路径，以实现为特定应用定制的属性和性能水平。它是一个复杂的，不确定的，多规模的，多功能的活动，需要多个合作的设计师和分布式的，异构的计算资源。因此，需要一种基于系统的设计方法来管理信息流，嵌入性能-属性-结构-处理关系，询问模型，探索可变性，并参与协作决策支持协议。在本文中，我们讨论了我们的系统为基础的材料设计方法的一些知识和计算基础。它有三个主要方面：（1）用于建模和支持复杂的协作设计过程的决策支持框架，（2）用于建模不确定性并管理或最小化其对设计规范的影响的鲁棒设计方法，以及（3）用于集成和共享异构信息以及计算和软件资源的计算基础设施。我们的方法的一些关键方面说明通过设计的多功能蜂窝材料的结构热交换器的应用。
Establishing systems-based materials design methods is an important step towards enabling rapid, concurrent design of materials and products with the potential for significant technological innovations. Materials design involves tailoring material structures and processing paths to achieve properties and performance levels that are customized for a particular application. It is a complex, non-deterministic, multi-scale, multifunctional activity that requires multiple collaborating designers and distributed, heterogeneous computing resources. Accordingly, a systems-based design approach is required with which to manage information flows, embed performance-property-structure-processing relations, interrogate models, explore variability, and engage collaborative decision-support protocols. In this paper, we discuss some of the intellectual and computing foundations of our systemsbased approach for materials design. It has three primary facets: (1) a decision support framework for modeling and supporting a complex, collaborative design process, (2) robust design methods for modeling uncertainty and managing or minimizing its impact on design specifications, and (3) a computational infrastructure for integrating and sharing heterogeneous information and computing and software resources. Some of the key aspects of our approach are illustrated via design of multifunctional cellular materials for a structural heat exchanger application.
