The small parameter method in the optimisation of a quasi-linear dynamical system problem

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2022
We consider an optimisation problem for the transient process in a quasi-linear dynamical system (contains a small parameter at non-linearities) with a performance index that is a linear combination of energy costs and the duration of the process.

Computationally efficient solution of mixed integer model predictive control problems via machine learning aided Benders Decomposition

open access: yes, 2023
Mixed integer Model Predictive Control (MPC) problems arise in the operation of systems where discrete and continuous decisions must be taken simultaneously to compensate for disturbances. The efficient solution of mixed integer MPC problems requires the

Online Power-Aware Deployment and Load Distribution Optimization for Application Server Clusters

open access: yesIEEE Access, 2019
The energy conservation of application server clusters is a pressing problem. In this paper, we propose an online power-aware deployment and load distribution optimization strategy for application server clusters, whose objective is to minimize the ...

A Greedy Heuristic for Maximizing the Lifetime of Wireless Sensor Networks Based on Disjoint Weighted Dominating Sets

open access: yesAlgorithms, 2021
Dominating sets are among the most well-studied concepts in graph theory, with many real-world applications especially in the area of wireless sensor networks. One way to increase network lifetime in wireless sensor networks consists of assigning sensors

Lagrangian relaxation heuristics for the uncapacitated single-source multi-product facility location problem [PDF]

open access: yes, 2013
Facility location problem is one of the strategic logistical drivers within the supply chain which is a hard to solve optimization problem. In this study, we focus on the uncapacitated single-source multi-product production/distribution facility location

Hard equality constrained integer knapsacks [PDF]

open access: yes, 2002
We consider the following integer feasibility problem: Given positive integer numbers a 0, a 1,..., a n, with gcd(a 1,..., a n) = 1 and a = (a 1,..., a n), does there exist a nonnegative integer vector x satisfying ax = a 0? Some instances of this type

Construction of Nodal Bubbling Solutions for the Weighted Sinh-Poisson Equation

open access: yesAbstract and Applied Analysis, 2013
We consider the weighted sinh-Poisson equation in , on , where is a small parameter, , and is a unit ball in . By a constructive way, we prove that for any positive integer , there exists a nodal bubbling solution which concentrates at the origin ...

An Evaluation of Mathematical Programming and Lower-Bound Methods for Hybrid Flow Shop Problems With a Makespan Criterion

open access: yesIEEE Access, 2023
This paper considers the hybrid flow shop scheduling problem, where jobs are processed in $m$ stages with the same route of the stage. Each stage has identical parallel machines for processing jobs.

Industrial water management by multiobjective optimization: from individual to collective solution through eco-industrial parks. [PDF]

open access: yes, 2012
Industrial water networks are designed in the first part by a multiobjective optimization strategy, where fresh water, regenerated water flow rates as well as the number of network connections (integer variables) are minimized.
