Concurrent Design for Functional Reliability and Failure Prognosis of Complex Engineered Systems

该奖项的研究目标是创建一个新的系统设计范式，称为顺序驱动的系统设计，使可靠的系统功能的并发开发和复杂的工程系统在不确定性下的功能故障的准确预测。复原力意味着感知和承受不良事件的能力，以及从不良事件的影响中恢复的能力。这项研究将量化工程弹性与严格的数学公式，开发预测弹性分析的新方法，并进一步创建一个新的设计范式，提供了一个独特的框架，考虑系统故障的预测和故障缓解/恢复活动在早期系统设计阶段。研究结果将使用基准设计问题进行验证和演示，以及基于与两个领先的行业合作伙伴的研究合作，解决航空系统和可持续能源系统的关键需求的实际设计应用。如果成功，这项研究将导致从传统的设计可靠性设计的弹性设计，通过开发新的设计理论和工具的设计范式转变。研究结果将促进通过将弹性设计到工程系统中来预防系统故障的理解。新的系统设计范例可能会刺激几个高科技行业的增长，例如数十亿美元的绿色能源发电、通用航空、汽车等，这些行业在后系统设计阶段遭受灾难性的系统故障和高维护成本。这项研究还将为工程设计，健康监测和故障预测领域的研究人员提供独特的研究和教育经验，并将在跨学科的学习环境中培养学生。将完成广泛的传播和推广计划，重点是促进数据共享，吸引学生从事工程职业和研究机会，以及妇女和代表性不足的群体的参与。

The research objective of this award is to create a new system design paradigm, referred to as resilience-driven system design, which enables concurrent developments of reliable system functions and accurate prognosis of function failures of complex engineered systems under uncertainty. Resilience implies the ability to sense and withstand adverse events, and to recover from the effects of the adverse events. This research will quantify engineering resilience with a rigorous mathematical formula, develop new methods for predictive resilience analysis, and further create a new design paradigm that offers a unique framework to consider prognosis of system failures and failure mitigation/recovery activities in the early system design stage. The research findings will be validated and demonstrated using benchmarking design problems, as well as practical design applications addressing the critical demands in aviation systems and sustainable energy systems based on the research collaborations with two leading industry partners. If successful, this research will lead to a design paradigm shift from conventional design for reliability to design for resilience by developing new design theory and tools. The research results will promote the understanding on preventing system failures through designing resilience into engineered systems. The new system design paradigm will likely stimulate growth in several high technology industries such as the multi-billion dollar green energy generation, general aviation, automobile, and more which suffer from catastrophic system failures and high maintenance costs at the post system design stages. This research will also offers unique research and educational experiences for researchers across the fields of engineering design, health monitoring and failure prognosis, and will train students in an interdisciplinary learning environment. A wide range of dissemination and outreach programs will be accomplished, with emphasis on promoting data sharing, attracting students to engineering career and research opportunities, and participation from women and underrepresented groups.
