A semidefinite programming approach for solving multiobjective linear programming
(Springer, 2014-03)
Several algorithms are available in the literature for finding the entire set of Pareto-optimal solutions in MultiObjective Linear Programming (MOLP). However, it has not been proposed so far an interior point algorithm ...

New models for the location of controversial facilities: A bilevel programming approach
(Elsevier, 2019-07)
Motivated by recent real-life applications in Location Theory in which the location decisions generate controversy, we propose a novel bilevel location model in which, on the one hand, there is a leader that chooses among ...

Continuous multifacility ordered median location problems
(Elsevier, 2016-04-01)
In this paper we propose a general methodology for solving a broad class of continuous, multifacility location problems, in any dimension and with ℓτ -norms proposing two different methodologies: 1) by a new second order ...

Rank aggregation in cyclic sequences
(Springer, 2016-05-10)
In this paper we propose the problem of finding the cyclic sequence which best represents a set of cyclic sequences. Given a set of elements and a precedence cost matrix we look for the cyclic sequence of the elements which ...

A market regulation bilevel problem: a case study of the Mexican petrochemical industry
(Elsevier, 2019-08)
In this paper, a bilevel programming model is proposed to study a problem of market regulation through government intervention. One of the main characteristics of the problem herein analyzed is that the government ...

Contributions to robust and bilevel optimization models for decision-making
(2019-03-15)
Los problemas de optimización combinatorios han sido ampliamente estudiados en la literatura especializada desde mediados del siglo pasado. No obstante, en las últimas décadas ha habido un cambio de paradigma en el ...

Unreliable point facility location problems on networks
(Elsevier, 2014-03)
In this paper we study facility location problems on graphs under the most common criteria, such as, median, center and centdian, but we incorporate in the objective function some reliability aspects. Assuming that facilities ...

Minimum spanning trees with neighborhoods: mathematical programming formulations and solution methods
(Elsevier, 2017-11-01)
This paper studies Minimum Spanning Trees under incomplete information for its vertices. We assume that no information is available on the precise placement of vertices so that it is only known that vertices belong to some ...

Cooperative location games based on the minimum diameter spanning Steiner subgraph problem
(Elsevier, 2012-05)
In this paper we introduce and analyze new classes of cooperative games related to facility location models. The players are the customers (demand points) in the location problem and the characteristic value of a coalition ...
