Abstract: With the passage of the 2018 U.S. Farm Bill, Industrial Hemp production ismoved from limited pilot programs to a regulated agriculture production system.However, Industrial Hemp Supply Chain (IHSC) faces critical challenges,including: high complexity and variability, very limited production knowledge,lack of data and information tracking. In this paper, we proposeblockchain-enabled IHSC and develop a preliminary simulation-based digital twinfor this distributed cyber-physical system (CPS) to support the processlearning and risk management. Basically, we develop a two-layer blockchain withproof of authority smart contract, which can track the data and keyinformation, improve the supply chain transparency, and leverage localauthorities and state regulators to ensure the quality control verification.Then, we introduce a stochastic simulation-based digital twin for IHSC riskmanagement, which can characterize the process spatial-temporal causalinterdependencies and dynamic evolution to guide risk control and decisionmaking. Our empirical study demonstrates the promising performance of proposedplatform.
