Ítem A Mixed-Integer Linear Programming Model for a Selective Vehicle Routing Problem(Springer International Publishing, 2018-09-03) Rivera, Juan Carlos; Posada, Andrea; PALACIO, JUAN DAVIDÍtem A Mixed-Integer Linear Programming Model for a Selective Vehicle Routing Problem(Springer International Publishing, 2018-09-03) Rivera, Juan Carlos; Posada, Andrea; PALACIO, JUAN DAVIDÍtem Effects on Electricity Markets of a Demand Response Model Based on Day Ahead Real Time Prices: Application to the Colombian Case(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2018-05-01) Rivera, Juan Carlos; Paramo, Oscar Alejandro; Lopez, Gustavo Adolfo; Rivera, Juan Carlos; Paramo, Oscar Alejandro; Lopez, Gustavo Adolfo; Universidad EAFIT. Departamento de Ciencias; Matemáticas y AplicacionesThis paper presents an alternative methodology, based on a cost optimization model, for evaluating some effects of the implementation of an alternative Demand Response (RD) program based on Day Ahead Real-Time Pricing (DA-RTP) in electricity markets. The proposed methodology has three special characteristics: the first one is to assume that users can modify their consumption patterns without altering the quantity demanded daily; second one, users flexibility to shift demand between hours depend of the kind of user and the time (peak vs off peak hours); finally, consumers have limited capability to shift demand outside of certain periods withing the day. The model is tested with a simulation exercise for the Colombian electricity market. The results show a significant improvement in system and market performance, including consumer savings, a flattened load curve, and reduced operational risk in the system. © 2003-2012 IEEE.Ítem Effects on Electricity Markets of a Demand Response Model Based on Day Ahead Real Time Prices: Application to the Colombian Case(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2018-05-01) Rivera, Juan Carlos; Paramo, Oscar Alejandro; Lopez, Gustavo Adolfo; Universidad EAFIT.

Departamento de Ciencias; Matemáticas y AplicacionesIn this paper we propose a new variant of the capacitated arc routing problem (CARP). In this new problem the objective function becomes a cumulative objective computed as the traveled distance multiplied by the vehicle load. A metaheuristic approach is proposed which is based on the hybridization of three known procedures: GRASP, VND and Set covering model. The metaheuristic is tested with some benchmark instances from CARP. The results allow to evaluate the performance with the different metaheuristic components and to compare the solutions with the classical objective function. © 2018, Springer Nature Switzerland AG.Ítem A Metaheuristic Approach for the Cumulative Capacitated Arc Routing Problem(Springer Verlag, 2018-09-03) Rivera, Juan Carlos; Lenis, Sergio Andres; Rivera, Juan Carlos; Lenis, Sergio Andres; Universidad EAFIT.
