A hyper-matheuristic approach for solving mixed integer linear optimization models in the context of data envelopment analysis [PDF]

open access: yesPeerJ Computer Science, 2022
Mixed Integer Linear Programs (MILPs) are usually NP-hard mathematical programming problems, which present difficulties to obtain optimal solutions in a reasonable time for large scale models.

Two hybrid flow shop scheduling lines with assembly stage and compatibility constraints. [PDF]

open access: yesPLoS ONE
Two hybrid flow shop scheduling lines must be coordinated to assemble batches of terminated products at their last stage. Each product is thus composed of two jobs, each produced in one of the lines.

A hybrid VNS matheuristic for a bin packing problem with a color constraint [PDF]

open access: yesYugoslav Journal of Operations Research, 2021
We study a new variant of the bin packing problem with a color constraint. Given a finite set of items, each item has a set of colors. Each bin has a color capacity, the total number of colors for a bin is the unification of colors for its items and ...

A Multi-Depot Vehicle Routing Problem with Stochastic Road Capacity and Reduced Two-Stage Stochastic Integer Linear Programming Models for Rollout Algorithm

open access: yesMathematics, 2021
A matheuristic approach based on a reduced two-stage Stochastic Integer Linear Programming (SILP) model is presented. The proposed approach is suitable for obtaining a policy constructed dynamically on the go during the rollout algorithm.

A Matheuristic Algorithm for the Multiple-Depot Vehicle and Crew Scheduling Problem

open access: yesIEEE Access, 2021
This work addresses the multiple-depot vehicle and crew scheduling problem (MDVCSP). In MDVCSP, we deal with two NP-hard problems in an integrated way: the multiple-depot vehicle scheduling problem (MDVSP) and the crew scheduling problem (CSP).
