Juegos con pagos vectoriales
(, 2002)
En este trabajo analizamos los diferentes aspectos de la teoría de juego con pagos vectoriales. El carácter vectorial de los pagos hace necesario revisar y redefinir los conceptos de la teoría de juegos clásica. Destacamos ...

Exact procedures for solving the discrete ordered median problem
(Elsevier, 2006-11)
The Discrete Ordered Median Problem (DOMP) generalizes classical discrete location problems, such as the N-median, N-center and Uncapacitated Facility Location problems. It was introduced by Nickel [S. Nickel. Discrete ...

The effect of consolidated periods in heterogeneous lotsizing games
(Springer, 2022)
We consider a cooperative game defined by an economic lot-sizing problem with heterogeneous costs over a finite time horizon, in which each firm faces demand for a single product in each period and coalitions can pool ...

Dynamically second-preferred p-center problem
(Elsevier, 2023)
This paper deals with the Dynamically Second-preferred p-center Problem (DSpP). In this problem, cus- tomers’ preferences and subsets of sites that each customer is willing to accept as service centers are taken into ...

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 ...

A mathematical programming approach to overlapping community detection
(Elsevier, 2022-06-02)
We propose a new optimization model to detect overlapping communities in networks. The model elaborates suggestions contained in Zhang et al. (2007), in which overlapping communities were identified through the use of a ...

Robust positioning of service units
(Taylor & Francis, 2003)
In this paper, we address the problem of locating mobile service units to cover random incidents. The model does not assume complete knowledge of the probability distribution of the location of the incident to be covered. ...

Multi-criteria analysis with partial information about the weighting coefficients
(ELSEVIER SCIENCE BV, 1993-04-01)
In this paper we address the problem of ranking a set of alternatives with partial information about the weighting coefficients. We introduce a family of quasiorders that are easily interpretable and manageable, which ...

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 ...
