Customers’ expectations of timely and accurate delivery pickup online purchases pose a new challenge to last-mile delivery. When the goods sent customers are not received, they must be returned warehouse. This situation provides high additional cost. Parcel locker systems convenience stores have been launched solve this problem serve as payment stations. research investigates distribution in au...

The Vehicle Routing Problem with Simultaneous Deliveries and Pickups (VRPSDP) has attracted great interest in research due to its potential cost savings to transportation and logistics operators. There exist several extensions of VRPSDP, and among these extensions, Simultaneous Deliveries and Pickups with Split Loads Problem (SDPSLP) is particularly proposed for eliminating the vehicle capacity...

In this paper, we consider a large-scale instance of the classical Pickup-and-Delivery Vehicle Routing Problem (PDVRP) that must be solved by network mobile cooperating robots. Robots self-coordinate and self-allocate set pickup/delivery tasks while minimizing given cost figure. This results in large, challenging Mixed-Integer Linear cooperatively % without central coordinator. We propose distr...

We present a two-echelon van-based robot last-mile pickup and delivery system in urban settings. Robots can visit areas with van access restrictions, such as pedestrianized or university campuses. The stops at parking nodes to drop off and/or pick up its robot, replenish swap robot’s battery if needed. Five van/robot cases are considered, according the roles plays process of pickup/delivery whe...
