Some relations between variational-like inequalities and efficient solutions of certain nonsmooth optimization problems
(Hindawi, 2006)
We study the equivalence between the solutions of the variational-like inequality problem and the solutions of certain nonsmooth and nonconvex vectorial optimization problem.

Flexible Log-Linear Birnbaum–Saunders Model
(MDPI, 2021-05-24)
Rieck and Nedelman (1991) introduced the sinh-normal distribution. This model was built as a transformation of a N(0,1) distribution. In this paper, a generalization based on a flexible skew normal distribution is introduced. ...

Computationally efficient goodness-of-fit tests for the error distribution in nonparametric regression
(Instituto Nacional de Estatística (Portugal), 2018-01)
Several procedures have been proposed for testing goodness-of-fit to the error distribution in nonparametric regression models. The null distribution of the associated test statistics is usually approximated by means of a ...

An exact global optimization method for deriving weights from pairwise comparison matrices
(Springer, 2006-09-06)
Some multiple-criteria decision making methods rank actions by associating weights to the different criteria or actions, which are pairwise compared via a positive reciprocal matrix A. There is a vast literature on proposals ...

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 ...

A fractional model for locating semi-desirable facilities on networks
(ELSEVIER SCIENCE BV, 2002-01-01)
In this paper, we address the problem of locating a series of facilities on a network maximizing the average distance to population centers (assumed to be distributed in the plane) per unit transportation cost (a function ...

On the Muth Distribution
(Vilnius teach journals, 2015-06-02)
The Muth distribution is a continuous random variable introduced in the context of reliability theory. In this paper, some mathematical properties of the model are derived, including analytical expressions for the moment ...

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 ...
