Perturbations are universal in supply chains, and their appearance is getting more frequent in the past few years. These perturbations affect industries and ...
BibTeX referenceA unified branch-price-and-cut algorithm for multi-compartment pickup and delivery problems
In this paper, we study the pickup and delivery problem with time windows and multiple compartments (PDPTWMC). The PDPTWMC generalizes the pickup and delive...
BibTeX referencePricing and unauthorized channel strategies for a global manufacturer considering import taxes
To cover the import taxes, a manufacturer typically charges a higher price in a foreign market than in its domestic market. The price difference can lead to ...
BibTeX referenceFluxNLPModels.jl and KnetNLPModels.jl: Connecting deep learning models with optimization solvers
This paper presents <code>FluxNLPModels.jl</code> and <code>KnetNLPModels.jl</code>, new Julia packages enabling a neural network, modelled with either Flux....

We consider a firm offering an opaque good over one selling season, that is, a product whose full characteristics are only revealed after the consumer comp...
BibTeX reference
We present a Julia framework dedicated to partially-separable problems whose element function are detected automatically. This framework takes advantage of ...
BibTeX referenceRobotic Process Automation (RPA) using a heuristic method and the effective resistance of a graph
Robotic Process Automation has emerged in recent years as an important field by allowing faster and more secure processes through a reduction in the risks or...

Given a set \(\mathcal{N}\)
of size \(n\)
, a non-negative, integer-valued distance matrix \(D\)
of dimensions \(n\times n\)
, an integer `(p\in\mathb...
Assessing electric mobility and renewable energy synergy in a small New Caledonia island community
In this paper, we evaluate the synergy between variable renewable energy (VRE), electric mobility, and Vehicle to Grid (V2G) deployment for a small community...

This paper presents \(\texttt{Krylov.jl}\)
, a Julia package that implements a collection of Krylov processes and methods for solving a variety of linear pr...
The Twelfth Montreal IPSW took place on August 22-26, 2022, and was jointly organized by the Centre de recherches mathématiques (CRM) and the Institute for D...

We develop a Levenberg-Marquardt method for minimizing the sum of a smooth nonlinear least-squares term \(f(x) = \tfrac{1}{2} \|F(x)\|_2^2\)
and a nonsmoo...
Decoupling spatial pattern and its movement via complex factorization over orthogonal filter pairs
Variations between related images (e.g. due to motions) can caused by different independent factors. A qualified representation can decouple the underlying...

Short-term production planning in mining complexes involves a series of decisions concerning activities and processes to accomplish the long-term planning ...
BibTeX referenceA simultaneous stochastic optimization framework for selecting additional infill drilling locations
An innovative simultaneous stochastic optimization approach is proposed that combines actor-critic reinforcement learning and stochastic mathematical progr...
