The impact of a financial constraint on the spatial structure of public transport services
(Springer Science+Business Media, 2014)
Using a single line model, it has been shown recently that the presence of a
stringent financial constraint induces a less than optimal bus frequency and larger than
optimal bus size. This occurs because the constraint ...
A framework to identify Pareto-efficient subdaily environmental flow constraints on hydropower reservoirs using a grid-wide power dispatch model
(Amer Geophysical Union, 2015)
Hydrologic alteration due to hydropeaking reservoir operations is a main concern worldwide. Subdaily environmental flow constraints (ECs) on operations can be promising alternatives for mitigating negative impacts. However, ...
The importance of time resolution, operational flexibility and risk aversion in quantifying the value of energy storage in long-term energy planning studies
(Elsevier Ltd, 2019)
This paper analyzes the impact of modeling detail in long-term energy planning models when assessing the value of energy storage in electricity markets. By running six optimization models for the long-term planning of ...
DESARROLLO E IMPLEMENTACIÓN DE UN MODELO DE TEORÍA DE RESTRICCIONES PARA SINCRONIZAR LAS OPERACIONES EN LA CADENA DE SUMINISTRO (DEVELOPMENT AND IMPLEMENTATION OF A THEORY OF CONSTRAINTS MODEL TO SYNCHRONIZE THE SUPPLY CHAIN OPERATIONS WITH PRODUCTION CON
(Fondo Editorial EIA - Universidad EIA, 2013-10-16)
En este artículo se presenta una propuesta metodológica y práctica que permite sincronizar las operaciones y las decisiones en una cadena de suministro de una empresa del sector de revestimientos cerámicos en Colombia. ...
Modeling the multi-seasonal link between the hydrodynamics of a reservoir and itshydropower plant operation
(MDPI AG, 2017)
The hydrodynamics of many hydropower reservoirs are controlled by the operation of their power plant, but the associated water quality impact is often poorly understood. In particular, significant hydropeaking operations ...
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 ...
Optimizing the multi-level location-assignment problem in queue networks using a multi-objective optimization approach
(Walter de Gruyter GmbHGermany, 2022)
Grid-wide subdaily hydrologic alteration under massive wind power penetration in Chile
(Elsevier, 2015)
Hydropeaking operations can severely degrade ecosystems. As variable renewable sources (e.g. wind power) are integrated into a power grid, fluctuations in the generation-demand balance are expected to increase. In this ...
A framework for consistences in association relations between classes in uml
(Universidad Nacional de Colombia Sede Medellín, 2014-08-26)
The following article shows the process of building and validating a framework for the management of consistencies in class diagrams in UML, operating specifically on class diagrams, through the application of transformation ...
