The proliferation of Mobile internet in all sectors and the continuous improvement in terms of chipset cost and poser consumption.
Moreover, the factory of the future is not expected as many devices each one acts alone by many devices processing together. This lead to a complex and multivariable processing that is executed as a distributed processing. Handling a huge amount of data, ensuring the processing of several devices, lead making the right decision as fastest as possible certainly lead to the Cloud connected devices. It is even considered of an essential value of the IoT (Geng et al., 2011).
One of the major barriers of migrated to interconnected manufacturing factories is the warranty about the stability and the effectiveness of such choice. In fact, it requires valid architecture to integrate effectively and easily the different connected objects. The architecture requires greater effort to support an intuitive translation from the physical world to a computerized and logical format that can be easily exploited for better Industry 4 adoption.
- • The architecture has also to distinguish clearly of two layers: the business layer (process) and the physical one (product and resources). This distinction is delicate to establish due the fact that IoT are devices, that when integrated into the manufacturing process, are considered as an integrated sub process.
- • Another important aspect is the mapping of two kinds of flows: physical flow and information one.
In Meyer (2013), the authors pointed the lack of modeling concepts to represent sensors and actuators of the IoT in a business process model. They consider it as a significant obstacle to successfully include real-world resources in traditional ERP systems business processes.
