在当今全球化、互联化和竞争激烈的市场中，现代复杂制造和服务（MCMS）系统（包括但不限于航空航天、交通运输和智能电网）以最高的可靠性充分发挥其潜力是至关重要的。由于退化和低质量部件，这种MCMS系统容易发生随机故障，这可能导致各种严重后果，从破坏基础设施到危及人类生命。为了避免代价高昂的故障，巨大的努力必须投入到质量和维护的概念，这是拟议的研究计划的目标领域。该研究计划的目标，题为“先进的机器学习技术故障诊断和预后：从现代复杂制造系统到医疗保健，”是调查和实施有前途的研究思路，在设计，开发，以及最先进的人工智能（AI）和机器学习（ML）技术的应用，有助于故障诊断的进步/过程监控和维护的自动化。 最近，随着计算和通信技术的进步，传感技术的进步已经导致高维和多模态流（HDMS）状态监测（CM）数据的指数增长。HDMS数据的有效利用导致过程/系统健康诊断/故障诊断中的高度准确的预测结果。为了实现上述目标（即，为了有效地利用这些不断增长的CM数据源），最近，对基于AI/ML的数据驱动方法的兴趣激增。与改变端到端商业模式的数字化类似，人工智能和机器学习将自己定位为世纪的变革性技术，给行业留下了两个选择：“通过人工智能/机器学习解决方案拥抱流程/系统监控，或者落后”。 这项研究计划的“共同主题”是应用先进的，混合的（即，再加上最先进的统计方法），以及用于过程质量控制、维护管理和生存分析的深度AI/ML技术。特别是，拟议的研究计划重点解决以下刚性的研究挑战：（一）如何监测和控制制造过程与HDMS数据？(ii)如何设计“深度”表示来监控/控制HDMS数据的制造过程/系统？(iii)如何制定最佳的维护政策，为MCMS系统受到退化通过HDMS数据？如何将联合收割机数据和CM数据结合起来？总之，建议的研究计划被认为是及时的，并在加拿大未来的质量控制和煤层气项目的发展具有重要意义。如果新知识证明像我希望的那样有价值，预计它们将对我们国家产生重大影响。

In today's globalized, interconnected, and competitive market, it is critical and of paramount importance that the Modern Complex Manufacturing and Service (MCMS) systems, including but not limited to aerospace, transportation and smart power grid, operate at their full potential with highest achievable reliability. Such MCMS systems are subject to random failures due to degradation and low-quality parts, which could lead to a variety of severe consequences ranging from destruction of infrastructures to endangering human lives. To avoid costly failures, tremendous efforts have to be invested in both Quality and Maintenance concepts, which are the target areas of the proposed research program. The objective of this research program, entitled "Advanced Machine Learning Techniques for Fault Diagnostics and Prognostic: From Modern Complex Manufacturing Systems to Healthcare," is to investigate and implement promising research ideas in the design, development, and application of state-of-the-art Artificial Intelligence (AI) and Machine Learning (ML) techniques that contribute to advancement of fault diagnostics/prognostics in process monitoring and maintenance. Recently, advancements in sensing technologies with progressive advancements in computation and communication technologies have resulted in exponential growth of high-dimensional and multi-modal streaming (HDMS) condition monitoring (CM) data. Efficient utilization of HDMS data leads to highly accurate prediction results in process/system health diagnostics/prognostics. To achieve the aforementioned goal (i.e., to efficiently utilize these ever growing sources of CM data), recently, there has been a great surge of interest in AI/ML based data-driven methodologies. Similar to digitalization which transformed end-to-end business models, the AI and ML are positioning themselves as the transformative technologies of the century leaving industries with two options: "Embrace the process/system monitoring via AI/ML solutions or get left behind''. The "Common Theme'' of this research program is to apply advanced, hybrid (i.e., coupled with state-of-the-art statistical methods), and deep AI/ML techniques for process quality control, maintenance management, and survival analysis. In particular, the proposed research program focuses to address the following rigid research challenges: (i) How to monitor and control manufacturing processes with HDMS data? (ii) How to design "deep'' representations to monitor/control manufacturing processes/systems with HDMS data? (iii) How to develop optimal maintenance policy for a MCMS system subject to degradation via HDMS data? How to combine event data and CM data? In conclusion, the proposed research program is believed to be timely and of significant importance for development of future quality control and CBM programs in Canada. Should the new knowledge prove as valuable as I hope, it is expected they will have a significant impact on our country.
