Assessing second‐price auctions for parcel exchanges in last‐mile logistics

International Transactions in Operational Research, EarlyView.
Abstract The rapid growth of e‐commerce has led to multiple carriers operating in the same regions, creating opportunities for collaboration. However, logistics companies typically operate independently, leading to inefficiencies. Horizontal cooperation, where carriers share resources and infrastructure, can improve efficiency and reduce costs.

A hybrid robust‐stochastic optimization approach for green hydrogen production planning under wind power forecast uncertainty

International Transactions in Operational Research, EarlyView.
Abstract This work aims at minimizing the energy purchase costs related to the operation of a green hydrogen production plant connected both to an intermittent, uncertain renewable energy source and to the power grid. We focus on scenarios where, for economic or environmental reasons, the plant must primarily meet hydrogen demand using electricity from

A genetic algorithm for scheduling an automated machine cell with tool and pallet–fixture setups

International Transactions in Operational Research, EarlyView.
Abstract This paper solves the scheduling problem of identical parallel machines with tooling and pallet–fixture constraints in a high‐mix, low‐volume, high‐complexity manufacturing environment. The machines are connected through an automated material handling device and in‐between buffer places that allow for autonomous production.

Learning optimal objective values for MILP

CoRR
Modern Mixed Integer Linear Programming (MILP) solvers use the Branch-and-Bound algorithm together with a plethora of auxiliary components that speed up the search. In recent years, there has been an explosive development in the use of machine learning for enhancing and supporting these algorithmic components. Within this line, we propose a methodology
