Due to the continued growth of online shopping and the corona 19 incident, the proportion of face-to-face shopping is decreasing, and the online shopping market is growing by expanding its proportion and scope. Due to the characteristics of online shopping, the demand for small package delivery is increasing dramatically. Increasing demand for delivery creates a significant load on the delivery logistics process. Among these processes, the unloading work at the logistics terminal, which is performed by manpower, is most affected by increasing demand. However, because of the poor working environment and frequent accidents, it is required to improve the working environment and efficiency of the delivery logistics terminal. In this study, a parcel unloading robot is suggested to improve the environment and efficiency of a terminal. and the operating and allocation policies of unloading robots are suggested. And to verify the efficiency of the robot installed terminal, the simulation experiments are conducted.
