An effective and efficient matheuristic for the electric vehicle routing problem with capacitated recharging stations

open access: yesInternational Transactions in Operational Research, Volume 34, Issue 2, Page 889-913, March 2027.
Abstract In this paper, we address the problem of routing a fleet of electric vehicles (EVs) to serve a set of customers, geographically distributed, within their time windows. We assume that EVs may also be recharged en route, and the amount of energy recharged at a recharging station (RS) is a decision variable itself, that is, partial recharges are ...

Park‐and‐multi‐loop with autonomous delivery robots in last‐mile logistics

open access: yesInternational Transactions in Operational Research, Volume 34, Issue 2, Page 914-945, March 2027.
Abstract This paper deals with the park‐and‐multi‐loop routing problem, in the context of last‐mile logistics, in which a fleet of traditional vehicles equipped with several autonomous delivery robots leaves from a depot to service a set of customer requests.

Optimization of structural assembly scheduling in the aeronautics industry

open access: yesInternational Transactions in Operational Research, Volume 34, Issue 2, Page 822-846, March 2027.
Abstract In the aeronautical industry, structural assembly refers to the stage in which parts, subassemblies, and main aircraft structures are fitted together, forming aerostructures. Aircraft structural assembly requires many complex activities to be performed over an intricate precedence network and is subject to interactions among the various ...

Heuristic approaches for a new variant of the team orienteering problem

open access: yesInternational Transactions in Operational Research, Volume 34, Issue 2, Page 975-1002, March 2027.
Abstract In this paper, we tackle the team orienteering problem (TOP) with service times, mandatory nodes and incompatibilities arising from two real‐world healthcare applications. We propose two heuristic algorithms: a variable neighbourhood descent algorithm and a matheuristic based on a cut separation approach.

Optimizing equity and efficiency in the aerial firefighting resource allocation problem

open access: yesInternational Transactions in Operational Research, Volume 34, Issue 2, Page 1072-1096, March 2027.
Abstract This study addresses the aerial firefighting resource allocation problem, formulated as the strategic prepositioning of a heterogeneous aerial firefighting fleet across capacity‐constrained airbases. A novel bi‐objective model is proposed that simultaneously optimizes efficiency (aggregate risk‐weighted accessibility) and equity (minimized ...
