Supply Chain 4.0 is transforming the way Supply Chains operate. Supply Chains can become more efficient, effective, and secure by using new technologies Some of the key technologies used in Supply Chain 4.0 include big data, blockchain, Artificial Intelligence, and the Internet of Things (IoT). Big data is being used to collect and analyse data from all parts of the Supply Chain. This data can improve decision-making, optimise processes, and predict demand. AI is being used to automate planning, scheduling, and forecasting tasks. AI can also identify patterns and anomalies in data. IoT is being used to connect devices and sensors in the Supply Chain. This connectivity allows for real-time monitoring and data collection. Blockchain is being used to create a secure, decentralised record of transactions. This can be used to track goods throughout the Supply Chain and ensure the authenticity of products.
