Branch-and-cut solution approach for multilevel mixed integer linear programming problems

open access: yesEURO Journal on Computational Optimization, 2023
A multilevel programming problem is an optimization problem that involves multiple decision makers, whose decisions are made in a sequential (or hierarchical) order. If all objective functions and constraints are linear and some decision variables in any

Capacitated Facility Location: Valid Inequalities and Facets [PDF]

open access: yesMathematics of Operations Research, 1995
We examine the polyhedral structure of the convex hull of feasible solutions of the capacitated facility location problem. In particular we derive necessary and sufficient conditions for a family of “effective capacity” inequalities to be facet-defining, and further results on a more general family called “submodular” inequalities.

Accelerated optimal maintenance scheduling for generation units on a truthful platform

open access: yesEnergy Reports, 2022
Maintenance of generation units is a measure to ensure the reliability of power systems. In this paper, a novel blockchain-based truthful condition-based maintenance of generation units (T-CBMGU) platform is proposed to innovate and upgrade state-of-the ...

The Referenced Vertex Ordering Problem: Theory, Applications, and Solution Methods

open access: yesOpen Journal of Mathematical Optimization, 2021
We introduce the referenced vertex ordering problem (revorder) as a combinatorial decision problem generalizing several vertex ordering problems that already appeared in the scientific literature under different guises.

A Stochastic Programming Model for Multi-Product Aggregate Production Planning Using Valid Inequalities

open access: yesApplied Sciences, 2022
In this study, a mixed integer, linear, multi-stage, stochastic programming model is developed for multi-product aggregate production planning (APP). An approximation is used with a model that employs discrete distributions with three and four values and
