AI总结：
本文分析了基于资产管理壳的协商过程在扩展应用中的效率，探讨了其在工业环境中的可扩展性及性能限制。
摘要：
主动的资产管理壳（AAS）实现了资产之间的双向通信。它使用VDI/VDE 2193中的I4.0组件语言来促进协商，例如将产品分配给可用的生产资源。本文研究了基于标准（如信息负载）的协商效率，以适用于具有扩展资产数量的应用。目前，AAS标准化的重点是子模型及其安全功能，以实现互操作的数据访问。其主动行为仍停留在概念层面，仍处于科学研究领域。现有研究检查了具有有限资产数量的主动AAS架构示例，引发了关于工业环境中的可扩展性问题。为了分析主动AAS用于扩展应用，引入了场景和评估标准。使用当前的主动AAS架构开发了一个可扩展的实现，并在资产数量变化时进行了实验。结果揭示了基于AAS的协商机制在扩展中的性能限制、通信开销和适应性。这些信息可以改进AAS的进一步开发和标准化。
英文摘要：
The proactive Asset Administration Shell (AAS) enables bidirectional communication between assets. It uses the Language for I4.0 Components in VDI/VDE 2193 to facilitate negotiations, such as allocating products to available production resources. This paper investigates the efficiency of the negotiation, based on criteria, such as message load, for applications with a scaling number of assets. Currently, the focus of AAS standardization is on submodels and their security to enable interoperable data access. Their proactive behavior remains conceptual and is still a subject of scientific research. Existing studies examine proactive AAS architecture examples with a limited number of assets, raising questions about their scalability in industrial environments. To analyze proactive AAS for scaling applications, a scenario and evaluation criteria are introduced. A scalable implementation is developed using current architectures for proactive AAS, upon which experiments are conducted with a varying number of assets. The results reveal the performance limitations, communication overhead, and adaptability of the AAS-based negotiation mechanism scaling. This information can improve the further development and standardization of the AAS.
