Integer programming formulations for the time-dependent elementary shortest path problem with resource constraints
(Elsevier Science, 2018)
In this paper we study the Time-Dependent Elementary Shortest Path Problem with Resource Constraints (TDESPPRC). We consider two integer programming formulations which exploit the characteristics of the time-dependent ...
Multicriteria optimization model for supply process problem under provision and demand uncertainty
(American Chemical Society, 2011-09)
Supply processes play an important role in customer satisfaction and company costs. The main characteristics of this problem are given by several decisions that follow a hierarchical structure and a very uncertain context, ...
Generalized disjunctive programming models for the truck loading problem: A case study from the non-alcoholic beverages industry
(Pergamon-Elsevier Science Ltd, 2020-08)
A real-world truck loading problem is considered for the major non-alcoholic beverages bottler in Argentina. The previous manual procedure to define the truck loading plan is improved by automatizing the process through a ...
Integer programming models for the routing and spectrum allocation problem
(Springer, 2018-10)
One of the most promising solutions to deal with huge data traffic demands in large communication networks is given by flexible optical networking, in particular the flexible grid (flexgrid) technology specified in the ...
A branch and cut algorithm for the time-dependent profitable tour problem with resource constraints
(Elsevier Science, 2021-03-16)
In this paper we study the time-dependent profitable tour problem with resource constraints (TDPTPRC), a generalization of the profitable tour problem (PTP) which includes variable travel times to account for road congestion. ...
Simultaneous lot-sizing and scheduling with recovery options: problem formulation and analysis of the single-product case
(Universidad Nacional del Sur, 2021)
We address an extension of the discrete lot-sizing and scheduling problem in which the demand of products can be also satisfied by remanufacturing used products returned to the origin. A mixed-integer linear programming ...
Some advances on Lovász-Schrijver semidefinite programming relaxations of the fractional stable set polytope
(Elsevier Science, 2014-02)
We study Lovász and Schrijver's hierarchy of relaxations based on positive semidefiniteness constraints derived from the fractional stable set polytope. We show that there are graphs G for which a single application of the ...
NMPC controller applied to the operation of an internal combustion engine: formulation and solution of the optimization problem in real time
(Springer-Verlag France, 2018-02-01)
Numerical optimization solve problems efficiently where such efficiency is focused on the speed with which the optimal x* is achieved, is open line of research and strong work in the scientific community in order to achieve ...
