Every asset in MF shop floor is designed and
modeled with an asset administration shell
(AAS). An AAS is a knowledge structure that
explains the asset type, its technical
functionality and its relationship with other
assets. 18 The reason for modeling the assets
with the AAS concept is to provide the
efficient integration of assets in a modular
way with high agility. There is vertical
integration constructed from machines,
equipment, stations and sensors to the ERP
system; and the horizontal integration
between all assets at the shop floor is also
established through an Industrial IoT (IIoT)
platform.
The gearbox production workflow in MF @
ARTC program is illustrated as shown in
Figure 3. This workflow is supported by the
digital system architecture described in
Figure 4. At the start of gearbox production
business, the e-commerce web page which
connects with the ERP system obtains any
gearbox order from the customers. The sale
orders are planned and scheduled for the
production accordingly with ERP and
scheduling systems. Those two systems are
connected with an IIoT software platform to
integrate with other system in the gearbox
production lines. The MES software links
with the IoT platform and other major
