Controlled markov chains : some stability problems
(UniandesMaestría en MatemáticasFacultad de CienciasDepartamento de Matemáticas, 2016)
"Along this work we study some stability-related problems in the context of Controlled Markov chains. As a first problem, we consider a division of the state space, and the goal is to construct a control policy such that ...
A hybrid evolutionary algorithm for vehicle routing problem with stochastic demands
(2015-03-09)
In this work we propose a hybrid dynamic programming evolutionary algorithm to solve the vehicle routing problem with stochastic demands, it is a well known NP-hard problem where uncertainty enhances the computational ...
Methodological and computational framework of stochastic programming and decisions under uncertainty
(UniandesMaestría en Ingeniería IndustrialFacultad de IngenieríaDepartamento de Ingeniería Industrial, 2019)
We study the Sample Average Approximation method for different types of problems. We discuss the implications of using different schemes of sampling (Uniform, Random and Importance sampling) and different risk measurements ...
Points-to analysis for context-oriented JavaScript programs
(Universidad de los AndesMaestría en Ingeniería de Sistemas y ComputaciónFacultad de IngenieríaDepartamento de Ingeniería Sistemas y Computación, 2022-06-15)
The purpose of this work is to improve the results of analyzers that could use the points-to sets as an input such as type checking by improving the precision of a points-to analysis for context-oriented JavaScript programs. ...
Algorithmic diversity through semantic program comparison
(Universidad de los AndesMaestría en Ingeniería de Sistemas y ComputaciónFacultad de IngenieríaDepartamento de Ingeniería de Sistemas y Computación, 2021)
La diversidad es una propiedad bien estudiada en el diseño de software, especialmente en áreas como la seguridad o los sistemas distribuidos. Sin embargo, a la hora de diseñar un sistema, no existen formas adecuadas de ...
Addressing the principal-agent problem in public private partnerships via mixed-integer bi-level linear programming
(Universidad de los AndesMaestría en Ingeniería IndustrialFacultad de IngenieríaDepartamento de Ingeniería Industrial, 2020)
Public Private Partnerships (PPPs) are associations between a government and a private party with the objective of delivering public assets and/or services. The private party provides financial leverage and technical ...
A column generation based heuristic for two-dimensional cutting stock problems with variable dimensions
(UniandesMaestría en Ingeniería IndustrialFacultad de IngenieríaDepartamento de Ingeniería Industrial, 2010)
In the Two-Dimensional Multiple Stock Size Cutting Stock Problem with Variable Dimensions (2D MSSCSP-VD) one wishes to fulfill the demand for a set of two-dimensional items out of a set of stock sheets, each of which has ...
A dynamic multi-trip location-routing problem with time windows
(Universidad de los AndesMaestría en Ingeniería IndustrialFacultad de IngenieríaDepartamento de Ingeniería Industrial, 2021)
The Dynamic Multi-trip Location-Routing Problem with Time Windows (DMLRPTW)consists on pairing strategic decisions of depot positioning and fleet sizing with operational vehicle routing decisions while taking into account ...
Bogotá Bien Alimentada como un problema lineal
(2009)
Se estudia una de las estrategias más visibles de la Política de seguridad alimentaria en Bogotá: los comedores comunitarios de Bogotá Bien Alimentada (BBA). Se hace un sumario de los conceptos de programación lineal que ...
On the design and control of compartmental networks for optimal evacuation and supply
(Universidad de los AndesMaestría en Ingeniería EléctricaFacultad de IngenieríaDepartamento de Ingeniería Eléctrica y Electrónica, 2017)
An optimization problem that minimizes the stable scaled consensus state for linear compartmental systems is proposed. The minimum scaled consensus state (MSCS) methodology is used to solve the optimal evacuation and supply ...
