System dynamics analysis of RFID-EPC's impact on reverse supply chain

摘要

RFID-EPC plays an important role in Internet of Things which will be the new environment of application of the reverse supply chain. By using RFID-EPC, the reverse supply chain under Internet of Things will have some characteristics. In order to analyze the impacts of RFID-EPC on reverse supply chain, on the assumption that RFID-EPC can reduce the collection uncertainty of the used-products, we present a system dynamics model and show the changing of the inventories, the service levels, and the profits. By analyzing the simulation results of the reverse supply chain with and without RFID-EPC, we can obtain that the service levels and the profits of the collector, the disassembly center, and the remanufacturer will increase even though their inventories increase when RFID-EPC is used in reverse supply chain.
