MaSiMO - Development and Research of Industry 4.0 Components with a Focus on Experimental Applications of Proactive Asset Administration Shells in Data-Driven Maintenance Environments

In the research agendas of the EU, the USA and many countries on the digitalization of industry and society, the creation of an Internet of Things (IoT) with its digital representations of assets is described as one of the most important transformations for future life and work. Many of the corresponding activities are summarized under the term Industry 4.0 (I4.0). The paper discusses how data-driven MRO can benefit from I4.0 developments, in particular by applying I4.0 components, which are the combination of an asset and its digital complement, the Asset Administration Shell. The paper proposes a data-centric MRO environment through the creation of a cyber-physical system for seamless and secure communication and smart interoperation between all stakeholders - such as humans, machines, or tangible and intangible products. In a conceptual design stage, the mandatory elements are introduced, such as independently operating proactive AAS, the necessary hardware adapters or the descriptive submodels of AAS with regard to the requirements of the MRO. The interactions between the AAS are based on their bidding capabilities, including the automated exchange and negotiation of tender documents, for which a structure is proposed. In an implementation scenario, the introduced concept is experimentally verified
