A system paradigm is a typical pattern or model of enterprise architectures (EAs) that describes constitutive system elements and their relations in achieving missions and goals of enterprises. A well-defined system paradigm and EA help enterprises in adopting appropriate manufacturing resources and technologies, optimizing plans, schedules, and controls of production lines, and coping with complexity, changes, and uncertainties of business processes cost-effectively. It is understandable that a system paradigm should be evolved along with the availability and advancement of advanced manufacturing technologies; on the other hand, new system paradigms are mostly inspired by some successful manufacturing applications of new information technologies (ITs). One of the recently developed system paradigms is Digital Manufacturing (DM) where Digital Twin (DT-I) is used to describe the interactions of virtual and physical entities. This paper discusses the concepts of DM and DT-I and rationalizes the relations of DM and DT-I; in particular, the origin and evolution of DT-I are explored in details to identify its limitations to be used as an EA for DM. It is our finding that existing IT concepts show their limitations in supporting smooth transitions when systems have to be reconfigured in dealing with long-term changes in Sustainable Manufacturing, and this is evidenced by the fact of the trend of the shortened lifespans of modern enterprises even with the aids of rapidly developed digital technologies in decades. To overcome these limitations, a new concept so called Digital Triad (DT-II) is coined and the Internet of Digital Triad Things (IoDTT) is proposed as an information integration (II) solution for digital manufacturing enterprises, and their application is illustrated through a reconfigurable robotic system example. The rationales and significances of DT-II and IoDTT as well as future research directions of DM are summarized as a conclusion.

用于可持续制造系统生命周期信息集成的新数字三元组 (DT-II) 概念

系统范式是企业架构 (EA) 的典型模式或模型,它描述了构成系统元素及其在实现企业使命和目标方面的关系。定义明确的系统范式和 EA 可帮助企业采用适当的制造资源和技术,优化生产线的计划、进度和控制,并以经济高效的方式应对业务流程的复杂性、变化和不确定性。可以理解,系统范式应该随着先进制造技术的可用性和进步而发展;另一方面,新系统范式主要受新信息技术 (IT) 的一些成功制造应用的启发。最近开发的系统范例之一是数字制造 (DM),其中数字孪生 (DT-I) 用于描述虚拟和物理实体的交互。本文讨论了DM和DT-I的概念,理顺了DM和DT-I的关系;特别是,详细探讨了 DT-I 的起源和演变,以确定其用作 DM EA 的局限性。我们发现,当系统必须重新配置以应对可持续制造的长期变化时,现有的 IT 概念在支持平滑过渡方面表现出局限性,现代企业寿命缩短的趋势甚至证明了这一点。借助数十年来快速发展的数字技术。为了克服这些限制,一个新的概念被称为 本文讨论了DM和DT-I的概念,理顺了DM和DT-I的关系;特别是,详细探讨了 DT-I 的起源和演变,以确定其用作 DM EA 的局限性。我们发现,当系统必须重新配置以应对可持续制造的长期变化时,现有的 IT 概念在支持平滑过渡方面表现出局限性,现代企业寿命缩短的趋势甚至证明了这一点。借助数十年来快速发展的数字技术。为了克服这些限制,一个新的概念被称为 本文讨论了DM和DT-I的概念,理顺了DM和DT-I的关系;特别是,详细探讨了 DT-I 的起源和演变,以确定其用作 DM EA 的局限性。我们发现,当系统必须重新配置以应对可持续制造的长期变化时,现有的 IT 概念在支持平滑过渡方面表现出局限性,现代企业寿命缩短的趋势甚至证明了这一点。借助数十年来快速发展的数字技术。为了克服这些限制,一个新的概念被称为 我们发现,当系统必须重新配置以应对可持续制造的长期变化时,现有的 IT 概念在支持平滑过渡方面表现出局限性,现代企业寿命缩短的趋势甚至证明了这一点。借助数十年来快速发展的数字技术。为了克服这些限制,一个新的概念被称为 我们发现,当系统必须重新配置以应对可持续制造的长期变化时,现有的 IT 概念在支持平滑过渡方面表现出局限性,现代企业寿命缩短的趋势甚至证明了这一点。借助数十年来快速发展的数字技术。为了克服这些限制,一个新的概念被称为数字三元组(DT-II) 被创造,数字三元组物联网(IoDTT) 被提出作为数字制造企业的信息集成 (II) 解决方案,并通过可重构机器人系统示例说明其应用。总结DT-II和IoDTT的基本原理和意义以及DM未来的研究方向。
