The study presented in this document proposes to address this challenge by modeling the operation of the Aguacatala station, focusing specifically on queue management, using the Discrete Event Simulation (DES) methodology. The impact of the available services at the station is evaluated through a baseline scenario, measuring wait times and queue lengths on the platform. As a result, visual outputs are generated to identify under which situations wait times and crowding conditions would exceed certain thresholds.Ítem Game Theory Modeling For Decentralized Peer-To-Peer Solar Energy Market In Colombian Nanogrids(Universidad EAFIT, 2022) Henao Ramírez, Tomás; García Rendón, John JairoAs microgeneration increases, the centralized model of electricity generation will be significantly altered. One of the new models being investigated is the notion of a peer-to-peer electricity market in which prosumers can market their electricity exports to any other household. This new kind of transactive energy market, and community or collective self-consumption, offer new models for trading energy locally. Over the past 10 years, there has been significant growth in the amount of academic literature and trial projects examining how these energy trading models might function. The results show that P2P energy trading provides significant financial and technical benefits to the community and is emerging as an alternative to cost-intensive energy storage systems. This paper investigates a possible game theoretic model for Colombian nanogrids and proposes a new algorithm for automating the sale and purchase of electricity in this market, aiming to optimize the market while providing increased control to householders. It is found that nanogrids may improve financial viability for solar systems at the residential level, concluding that the future for residential solar prosumers is beyond isolated self-consumption.Ítem Generalized Simulated Annealing Algorithm for Matlab(Universidad EAFIT, 2019-11-29) Wilches Visbal, Jorge Homero; Martins Da Costa, Alessandro; Universidad del MagdalenaMany problems in biology, physics, mathematics, and engineering, demand the determination of the global optimum of multidimensional functions. Simulated annealing is a meta-heuristic method that solves global optimization problems. There are three types of simulated annealing: i) classical simulated annealing; ii) fast simulated annealing and iii) generalized simulated annealing. Among them, generalized simulated annealing is the most efficient. Matlab is one of the most widely software used in numeric simulation and scientific computation. Matlab optimization toolbox provides a variety of functions able to solve many complex problems. In this article, the generalized simulated annealing method was described, the GSA function that contains this method was applied to some mathematical problems were solved in order to evaluate the efficiency of GSA with respect to some of Matlab optimization functions. As a result, it was found that the GSA function not only manages to be effective in its convergence to the global optimum but also it does so quickly. Likewise, it was observed that, in general terms, GSA was more efficient than the functions with which it was compared. Therefore, it can be concluded that the GSA function is a novel and effective alternative for addressing optimization problems using Matlab.Ítem MAF Challenge Express Luck Colombia S.A.S.(Universidad EAFIT, 2022) Cala Barrera, Diego Armando; Racines Carvajal, Luis Alfredo; Herrera Echeverri, Hernán HumbertoExpress Luck Colombia S.A.S. is a subordinate company from Express Luck general headquartes in China.
