On Minimal Valid Inequalities for Mixed Integer Conic Programs [PDF]

open access: yesMathematics of Operations Research, 2015
We study disjunctive conic sets involving a general regular (closed, convex, full dimensional, and pointed) cone K such as the nonnegative orthant, the Lorentz cone or the positive semidefinite cone.

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

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

On the Fractional Maximal Delta Integral Type Inequalities on Time Scales

open access: yesFractal and Fractional, 2020
Time scales have been the target of work of many mathematicians for more than a quarter century. Some of these studies are of inequalities and dynamic integrals. Inequalities and fractional maximal integrals have an important place in these studies.

The Violation of Bell-CHSH Inequalities Leads to Different Conclusions Depending on the Description Used

open access: yesEntropy, 2021
Since the experimental observation of the violation of the Bell-CHSH inequalities, much has been said about the non-local and contextual character of the underlying system.
