Digging Deep: Dynamic Programming for Optimal Routing With Double‐Deep Autonomous Mobile Robot Picking

open access: yesNetworks, EarlyView.
ABSTRACT Multi‐tote autonomous mobile robots (MT‐AMRs) are an emerging warehousing technology in which a mobile drive unit carries a lift‐based storage‐and‐retrieval mechanism with an extendable fork and a multi‐tote onboard buffer. On autonomous picking tours, an MT‐AMR visits storage locations, extracts product totes from racks, stores them in its ...

A Two‐Stage Optimization Approach for Selecting Electric‐Flight Airports

open access: yesNetworks, EarlyView.
ABSTRACT The decarbonization of short‐haul air transport has gained increasing attention, with electric aircraft emerging as a promising alternative to conventional short‐haul aviation. However, given the substantial investment anticipated for the necessary infrastructure, a strategic and globally coordinated selection of airports is imperative.

The Single Picker Routing Problem with Scattered Storage in Parallel‐Aisle Warehouses With Multiple Blocks

open access: yesNetworks, EarlyView.
ABSTRACT This paper investigates the b$$ b $$‐block single picker routing problem with scattered storage (b$$ b $$‐SPRP‐SS). For a parallel‐aisle warehouse comprising b$$ b $$ blocks, the b$$ b $$‐SPRP‐SS asks for the determination of a picker tour that minimizes travel distance while collecting all articles from a given pick list.

A Supervised Learning Framework for Accelerating Solvers and Metaheuristics in Routing Problems

open access: yesNetworks, EarlyView.
ABSTRACT Routing problems such as the traveling salesman problem (TSP) and the capacitated vehicle routing problem (CVRP) are computationally challenging due to the exponential growth of their feasible solution spaces with increasing instance size.

Exact Solution of Picker Routing Problems in Zoned Warehouses With Scattered Storage

open access: yesNetworks, EarlyView.
ABSTRACT We present two picker routing problems in a warehouse split into multiple disjoint zones with a picker assigned to each zone. Scattered storage is applied, meaning an article can be stored at several pick positions in one or more zones, and capacity restrictions limit the number of collected articles for each picker.
