Drive, Pack, Fly: The Travelling Thief Problem with Drone
Kabir Murjani, Abhay Sobhanan
In collection operations, accumulating payload progressively slows the vehicle, imposing a cumulative penalty on routing efficiency. An onboard drone can offset this penalty by ret…
Deep Reinforcement Learning for Dynamic Battery Management of Autonomous Order Pickers
Taniya Shaji, Abhay Sobhanan, Christof Defryn
Battery charging of Autonomous Mobile Robots (AMRs) in warehouses is a critical operational challenge that heavily impacts both order processing times and throughput. In this study…
Arc Routing Problems with Multiple Trucks and Drones: A Hybrid Genetic Algorithm
Abhay Sobhanan, Hadi Charkhgard, Changhyun Kwon
Arc-routing problems underpin numerous critical field operations, including power-line inspection, urban police patrolling, and traffic monitoring. In this domain, the Rural Postma…
Deep Reinforcement Learning for Dynamic Order Picking in Warehouse Operations
Sasan Mahmoudinazlou, Abhay Sobhanan, Hadi Charkhgard +2
Order picking is a pivotal operation in warehouses that directly impacts overall efficiency and profitability. This study addresses the dynamic order picking problem, a significant…
Genetic Algorithms with Neural Cost Predictor for Solving Hierarchical Vehicle Routing Problems
Abhay Sobhanan, Junyoung Park, Jinkyoo Park +1
When vehicle routing decisions are intertwined with higher-level decisions, the resulting optimization problems pose significant challenges for computation. Examples are the multi-…
Optimal control for production inventory system with various cost criterion
Subrata Golui, Chandan Pal, Manikandan R. +1
In this article, we investigate a dynamic control problem of a production-inventory system. Here, demands arrive at the production unit according to a Poisson process and are proce…
