Several actors are involved in the transport of goods. To model freight transport, the di erent actors who take part in the decision making process have to be represented. In Maes et al. (2012) a conceptual framework is presented to model freight transport. The key actors in this framework are rms, carriers, and forwarders. This allows the model to work on an activity-based level, focusing on t...

Abstract Task scheduling (TS) and multi-agent-path-finding (MAPF) are two cruxes of pickup-and-delivery in automated warehouses. In this paper, the optimized simultaneously. Firstly, system model, task path model established, respectively. Then, a algorithm based on enhanced HEFT, heuristic MAPF TS- proposed to solve combinatorial optimization problem. EHEFT, novel rank priority rule is used de...

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...
