We consider the problem of scheduling maintenance for a collection of machines under partial observations when the state of each machine deteriorates stochas...

In this paper, we introduce a new variant of the vehicle routing problem with time windows (VRPTW) that arises in parcel delivery by postal services. In addi...

This paper presents the properties of the minimum mean cycle-canceling algorithm for solving linear programming models. Originally designed by Goldberg ...
BibTeX referenceParallel stimulation of disruptions for personnel scheduling in a flexible working environment
Personnel scheduling aims to determine least-cost personnel schedules to meet the demand for employees in each period of a planning horizon. In this article,...
BibTeX referenceDeep-learning-based partial pricing in a branch-and-price algorithm for personalized crew rostering
The personalized crew rostering problem (CRP) consists of assigning pairings (sequences of flights, deadheads, connections, and rests, forming one or several...
BibTeX referenceAn improved integral column generation algorithm using machine learning for aircrew pairing
The crew pairing problem (CPP) is solved in the first step of the crew scheduling process. It consists of creating a set of pairings (sequence of flights, co...
BibTeX reference
We consider logistic collaborations where multiple carriers collaborate by consolidating demands, combining delivery routes, and serving new customers. Logis...
BibTeX reference
We represent a closed-loop supply chain formed of one manufacturer and one retailer as a dynamic game played over an event tree, which naturally allows to ...
BibTeX reference
Given a set of predefined duties and groups of drivers, the duty assignment problem with group-based driver preferences (DAPGDP) aims at building rosters tha...
BibTeX reference
We study a new variant of the well-studied Vehicle Routing Problem with Time Windows (VRPTW), called the fragility-constrained VRPTW, which assumes that ...
BibTeX referenceVessel service planning in seaports
Berth allocation and pilotage planning are the two most important decisions made by a seaport for serving incoming vessels. Traditionally, the berth allocati...

Scholars and practitioners have long recognised the importance of data-driven operations and supply chain management (OSCM), which typically centres on produ...
BibTeX referenceStochastic dual dynamic programming for multi-echelon lot-sizing with component substitution
This work investigates lot-sizing with component substitution under demand uncertainty. The integration of component substitution with lot-sizing in an uncer...
BibTeX reference
We consider the problem of designing vehicle routes in a distribution system that are at the same time cost-effective and visually attractive. In this pape...
BibTeX referenceA branch-price-and-cut algorithm for the two-echelon vehicle routing problem with time windows
In this paper, we propose an exact branch-price-and-cut (BPC) algorithm for the two-echelon vehicle routing problem with time windows. This problem arises i...
BibTeX reference
This paper studies disjunctive cutting planes in Mixed-Integer Conic Programming. Building on conic duality, we formulate a cut-generating conic program for...
BibTeX reference
We study a distributionally robust version of the classical capacitated facility location problem with a distributional ambiguity set defined as a Wasserst...
BibTeX reference
We study a new variant of the vehicle routing problem, which arises in hospital-wide scheduling of physical therapists. Multiple service locations exist for...
BibTeX reference
Column generation (CG) algorithms are well known to suffer from convergence issues due, mainly, to the degenerate structure of their master problem and the ...
