The importance of last-mile delivery (LMD) performance for customer satisfaction has increased dramatically due to the significant demand surge in online shopping with the COVID-19 pandemic. To satisfy the increased customer expectations for faster, more convenient, more transparent, and cheaper deliveries, many LMD providers started to invest in new technologies and adopt new delivery vehicles and distribution strategies. This research presents a comprehensive examination of new disruptive technologies and strategies, including AI/ML, Big Data Analytics, Physical Internet, Blockchain, Digital Twins, IoT, 3D printing, AR/VR, low/zero emission, and autonomous vehicles, microhubs, and mobile parcel lockers, in LMD operations. We critically review their state-of-the-art applications, outline future directions, and discuss potential barriers to implementing these technologies to improve LMD performance.
