Dynamic Risk Assessment by Communicating Objects in Supply Chain of Chemicals

In this paper, a wireless sensor network is deployed to improve the security of goods, environment and persons along a supply chain manipulating chemicals in the European Union. Pallets are equipped with a RFID tag and a set of sensors that monitor in real-time the environment state. By defining and monitoring constraints that must satisfy pallet environments, a real-time risk assessment is proposed. Then, sensors send accident risks in case of unusual values to a centralized software. Supply chain actors responsible for goods are thus contacted and in parallel emergency services are contacted to plan and organize their interventions.
