Innovative Scheduling Algorithms to Improve Port Operations

Ports have been bearing the brunt of the impact for months from the different interferences along the supply chain. The pandemic has only exacerbated an already existing problem, as ports and their operations have always been the weakest link of the supply chain network. A particularly significant part of the problem is associated with the scheduling and routing of AGVs (Automated Guided Vehicles) which are performing loading and unloading operations following specific logics. This scheduling problem is modeled with very complex mathematical formulation, inherently difficult to solve, also due to their combinatorial nature. Many significant delays occur due to lack of coordination between the vehicles and the Cranes and Trucks, at both other ends of the port logistics. This is due to uncertainty and lack of reliable forecasts of arrivals, but also to the lack of proper control mechanisms to overcome and prevent this lack of synchronization. This research project will explore these challenges and propose innovative solutions to this complex problem by developing algorithms and solution methods.
