针对AAS实例比较缺乏方法论和成熟度模型的问题，提出基于数字孪生标准的AAS成熟度概念，实现实例可比性，支持工程发展步骤评估。
AI 中文摘要
资产管理外壳（AAS）日益被认为是制造业中数字孪生实现及数据交换的基础模型。AAS定义了一种分层数据结构，用于在整个生命周期中表示任何类型的资产。在基于AAS的系统中，比较不同的AAS实例构成了一项实际挑战，因为目前既没有广泛接受的方法论框架，也没有成熟度模型来系统性地支持此类分析。为弥补这一空白，我们提出了AAS成熟度的新概念，该概念表征了既定数字孪生标准被满足的程度，从而使AAS实例具有可比性。这些概念源自文献，并通过实例化应用加以说明。这些初步成果使从业者和研究人员能够系统地比较AAS实例，并支持在数字孪生工程过程中识别和评估进一步的发展步骤。
英文摘要
The Asset Administration Shell (AAS) is increasingly recognized as a fundamental model for the realization of and data exchange between digital twins in manufacturing. An AAS defines a hierarchical data structure to represent any type of asset throughout its entire lifecycle. In the context of AAS-based systems, comparing different AAS instances constitutes a practical challenge, as neither a widely accepted methodological framework nor a maturity model are available to systematically support such analyses. To address this gap, we propose a novel concept of AAS maturity that characterizes the extent to which established digital twin criteria are met and thus enabling comparability of AAS instances. The concepts are derived from the literature and applied through exemplification. These emerging results enable practitioners and researchers to systematically compare AAS instances and support the identification and assessment of further development steps in the digital twin engineering process.
