数字孪生自适应制造

Self-Adaptive Manufacturing with Digital Twins

Tim Bolender, Gereon Bürvenich, Manuela Dalibor, Bernhard Rumpe, Andreas Wortmann

摘要:

数字双胞胎是工业4.0愿景的一部分,旨在表示、控制、预测和优化网络物理生产系统(CPPS)的行为。这些CPPS是针对不同环境部署和配置的长寿复杂系统。由于特定的部署、配置、磨损或其他环境影响,它们的行为可能会随着时间的推移而偏离预期行为。适当地调整CPPS的配置则依赖于人类操作员的专业知识。数字双胞胎(DT)将这种专业知识具体化,并从中学习以应对不可预见的挑战,可以显著促进自适应制造,其中经验非常具体,因此不足以采用深度学习技术。我们通过基于案例的推理利用领域专业知识的显式建模来提高数字双胞胎适应这种情况的能力。为此,我们提出了一个自适应制造的建模框架,支持建模领域特定的情况下,描述规则的情况下相似性和基于案例的推理在一个模块化的数字孪生。基于明确建模的领域专业知识自动配置数字孪生模型可以缩短制造时间,减少浪费,并最终有助于更好地实现可持续制造。

英文摘要:

Digital Twins are part of the vision of Industry 4.0 to represent, control, predict, and optimize the behavior of Cyber-Physical Production Systems (CPPSs). These CPPSs are long-living complex systems deployed to and configured for diverse environments. Due to specific deployment, configuration, wear and tear, or other environmental effects, their behavior might diverge from the intended behavior over time. Properly adapting the configuration of CPPSs then relies on the expertise of human operators. Digital Twins (DTs) that reify this expertise and learn from it to address unforeseen challenges can significantly facilitate self-adaptive manufacturing where experience is very specific and, hence, insufficient to employ deep learning techniques. We leverage the explicit modeling of domain expertise through case-based reasoning to improve the capabilities of Digital Twins for adapting to such situations. To this effect, we present a modeling framework for self-adaptive manufacturing that supports modeling domain-specific cases, describing rules for case similarity and case-based reasoning within a modular Digital Twin. Automatically configuring Digital Twins based on explicitly modeled domain expertise can improve manufacturing times, reduce wastage, and, ultimately, contribute to better sustainable manufacturing.
