New geometrical compactness measures for zones design
Nuevas medidas de compacidad geométrica para el diseño de zonas
(2012-07-01)
The design of compact zones has been studied because of its influence in the creation of zones with regular forms, which are easier to analyze, to investigate or to administer. This paper propose a new method to measure ...
Aplicación de la búsqueda tabú en regresión no lineal
Aplicación de la búsqueda tabú en regresión no lineal
(2009-02-20)
We implement the combinatorial optimization technique known as tabu search inthe parameter estimation problem in a given non linear model. For the generationof neighbors, the implementation is based on a discretization of ...

The Robust Coloring Problem (RCP) is a NP-Hard Problem for which fast andefficient heuristic algorithms has been developed. In this work we present as a PCRthe problem of assignment of frequencies for a cellphone grid. ...
Una caracterización sobre las soluciones para el problema de reaprovisionamiento conjunto
Una caracterización sobre las soluciones para el problema de reaprovisionamiento conjunto
(2009-02-20)
In this paper an introduction is given to a multiple-item inventory problem, knownas the Joint Replenishment Problem (JRP). This is a real world problem which hasbeen extensively studied. The JRP has a continuous decision ...

(2009-02-19)
En este artículo se desarrolla un algoritmo heurístico y su correspondiente implementación para resolver un problema de localización de plantas (facility location) de gran escala, en donde surgen potencialmente más de 640 ...
Simulated Annealing–Golden section algorithm for the multiproduct replenishment problem with stochastic demand.
Algoritmo recocido simulado–sección dorada para el problema de reaprovisionamiento multiproducto con demanda estocástica
(2010-07-02)
The joint replenishment problem (JRP) has been studied for over 30 years and there are both heuristic and exact algorithms to determine the frequency of orders and fundamental cycle; in recent years ithas been considered ...
Optimal design of networks and routing of computers: practical case
Diseño óptimo de redes y enrutamiento de computadoras: Caso Práctico
(2010-04-16)
This work introduced to the problem of routering and optimum design of networks of computers that must satisfy certain practical conditions of interconnectivity. This paper show an approach style Steiner problems, and ...
Fuzzy Regression VS. Ordinary Least Squares Regression: Case Study
Regresión Borrosa VS. Regresión por Mínimos Cuadrados Ordinarios: Caso de Estudio
(2011-03-18)
The objective of this paper is to disseminate the technique of fuzzy regression and to give a practical example of its use. To this end, classical regression is compared to several fuzzy regression models on a problem ...
