    Autonomous delivery robot (ADR) operation for short-range delivery purposes is becoming increasingly popular, and assigning orders to robots is crucial in ensuring high service quality. This paper considers a dynamic pickup and delivery problem with external demand using autonomous robots (DPDP-EDAR). A fleet of autonomous delivery robots picks up the item from the stores and delivers it to the customers. The arrival time, pickup location, and delivery locations of orders are uncertain. There exists a hard delivery deadline for each order. Rejection of orders is possible, but a penalty cost is imposed per rejection. Battery recharging strategy is addressed for the operation of battery-powered ADR. To handle this stochasticity and dynamism in the problem, we develop a reassignment policy that reschedules previously assigned orders at the arrival of the new order. Additionally, as peak time can be obtained from the external source of demand, peak time management of the battery is proposed to enhance ADR utilization at peak times. Computational experiments are performed on real-world ADR food delivery service instances in an airport terminal. We show how devised policies improve service quality compared to the current practice.
