A Polyhedral-Based Approach Applied to Quadratic Cost Curves in the Unit Commitment Problem
(IEEE, 2016)
This paper presents a new polyhedral approximation for the quadratic cost curve of thermal units for the unit commitment problem. The approximation is tight, can be represented by rational numbers, and its size grows ...
Feature selection for Support Vector Machines via Mixed Integer Linear Programming
(Elsevier, 2014)
The performance of classification methods, such as Support Vector Machines, depends
heavily on the proper choice of the feature set used to construct the classifier. Feature
selection is an NP-hard problem that has been ...
A mixed-integer linear programming model for harvesting, loading and transporting sugarcane. A case study in Peru
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2016-01-01)
Due to opportunities for economic and social development in the biofuels market, improvement to the supply chain has become a relevant matter. In agro-industrial supply chains, procurement costs are highly relevant. Since ...
A new hybrid heuristic algorithm for the Precedence Constrained Production Scheduling Problem: A mining application
(Elsevier, 2020)
In this work we address the Precedence Constrained Production Scheduling Problem (PCPSP), the problem of scheduling tasks in such a way that total profit is maximized, while satisfying conditions such as precedence constraints ...
A new hybrid heuristic algorithm for the Precedence Constrained Production Scheduling Problem: A mining application
(Elsevier Ltd, 2019)
In this work we address the Precedence Constrained Production Scheduling Problem (PCPSP), the problem of scheduling tasks in such a way that total profit is maximized, while satisfying conditions such as precedence constraints ...
Joint location-inventory problem with differentiated service levels using critical level policy
(Elsevier, 2015)
This paper analyzes the design of a distribution network for fast-moving items able to provide differentiated service levels in terms of product availability for two demand classes (high and low priority) using a critical ...
Locating sea ambulances to respond to emergencies of vulnerable populations. Case of Cartagena bay in Colombia
(Springer International Publishing, 2021)
A study of general and security Stackelberg game formulations
(Elsevier, 2019)
In this paper, we analyze different mathematical formulations for general Stackelberg games (GSGs) and Stackelberg security games (SSGs). We consider GSGs in which a single leader commits to a utility maxi- mizing strategy ...
Design of a single window system for e-government services: the chilean casee
(American Institute of Mathematical Sciences, 2018-04)
The single window concept refers to systems that allow organizations to provide one-stop services to users. This paper describes a model for the design of a single window system in the context of e-government. The model ...
