Abstract—In today’s digital era, businesses are increasingly adopting advanced technologies to optimize their supply chain processes. The adoption of technologies like the Internet of Things (IoT), AI, drones, and robotics is required. However, integrating these technologies into current supply chain processes has different issues and limitations. Although there are different studies that have been conducted in Digital Supply Chain Management (DSCM), there is still a noticeable need to focus on IoT-based supply chain management to enhance supply chain efficiency and decision-making capabilities. Consequently, this paper provides a review of the previous studies that were conducted on the IoT-based SCM. Also, a comparison between these studies that considers different factors, such as domain, technologies, dataset, hardware and software, and evaluation metrics, is provided. Furthermore, the paper examines the potential challenges and future trends in this field.
