A Fog Computing Framework for Blackberry Supply Chain Management

With the rapid proliferation of RFID systems in global supply chain management, tracking every object at the individual item level has led to the generation of enormous amount of data that will have to be stored and accessed quickly to make real time decisions. This is especially critical for perishable produce supply chain such as fruits and pharmaceuticals which have enormous value tied up in assets and may become worthless if they are not kept in precisely controlled and cool environments. While Cloud-based RFID solutions are deployed to monitor and track the products from manufacturer to retailer, we argue that Fog Computing is needed to bring efficiency and reduce the wastage experienced in the perishable produce supply chain. This paper investigates in-depth: (i) the application of fog computing in perishable produce supply chain management using blackberry fruit as a case study; and (ii) the data, compute and storage requirements for the fog nodes at each stage of the supply chain. In the process, we discuss the benefits of the proposed fog nodes with respect to monitoring and actuation in the blackberry supply chain.
