(ELSEVIER, 2008-09-01)In recent years, there has been a growing trend to out-source service operations in which the equipment maintenance is carried out by an external agent rather than in-house. Often, the agent (service provider) offers more ...
-
(Informs, 2016)We study the design of mechanisms for a sequencing problem where the types of job-agents consist of processing times and waiting costs that are private to the jobs. In the Bayes-Nash setting, we seek to find a sequencing ...
-
(Institute of Electrical and Electronics Engineers Inc., 2018)This paper presents a heuristic model that optimally deploys the resources used to obtain a metropolitan and neighborhood area network with connectivity between the central office of an electricity company and the integrated ...
-
(MDPI, 2020)We describe an algorithm computing an optimal prefix free code for n unsorted positive weights in time within O(n(1+lg alpha))subset of O(nlgn), where the alternation alpha is an element of[1..n-1] approximates the minimal ...
-
(Elsevier, 2016)Travelcards are used in many parts of the developed world as a form of payment for public transport that is convenient for frequent users. In essence it involves a one-time payment T at the beginning of a period that covers ...
-
(Universidad de Chile, 2022)En este trabajo se estudian tres problemas. Primero, se resuelve el problema de un vendedor dotado de infinitas unidades de cierto producto homogéneo para la venta en un horizonte finito y discreto con el fin de maximizar ...
-
(Univ. Bath., 2015)In this paper, marginal cost-pricing rules are applied to an agent-based model. User-specific optimal bus fares are estimated by simulating user interactions at a microscopic level. We consider external effects of prolonged ...
-
(ELSEVIER, 2006-02)In this article, we develop a model to help a maintenance decision making situation of a given equipment. We propose a novel model to determine optimal life-cycle duration and intervals between overhauls by minimizing ...
-
(Springer Science+Business Media, 2014)This paper proposes a multi-criteria approach that accounts for the risk of fire when determining the optimal rotation of a forest stand that is being managed for both timber production and carbon sequestration purposes. ...
-
(Universidad de Chile, 2021)La inferencia de parámetros orbitales para sistemas binarios es extremadamente importante para el estudio evolutivo del universo, puesto que dichos parámetros orbitales permiten inferir las masas individuales de los ...
-
(2007)A recent trend to improve the effectiveness of similarity queries in multimedia databases is based on dynamic combinations of metric spaces. The efficiency issue when using these dynamic combinations is still an open ...
-
(Springer New York LLC, 2019)© 2018, Springer Science+Business Media, LLC, part of Springer Nature.It is well known since Wu and Wu (in: Proceedings of the 14th symposium on naval hydrodynamics, National Academy Press, Washington, pp 103–125, 1982) ...
-
(Universidad de Chile, 2016)Actualmente existen diversos problemas medioambientales, dos de ellos corresponden a la futura crisis energética, debido al agotamiento de los combustibles fósiles, y a la existencia de aguas residuales con altas concentraciones ...
-
(Universidad de Chile, 2017)En este trabajo estudiamos un par de problemas de la teoría de paradas óptimas, y mostramos cómo aplicar estos resultados en el diseño de mecanismos. Consideramos dos versiones modificadas de la famosa desigualdad del ...
-
(MDPI AG, 2019)In this paper, we report an application for the mathematical theory of dynamic optimization for design of optimal strategies that account for daily commuting of human residents, aiming to reduce vector-borne infections ...
-
(ELSEVIER SCIENCE BV, 2008-09)The optimal positioning of switches in a mobile communication network is an important task, which can save costs and improve the performance of the network. In this paper we propose a model for establishing which are the ...
-
(Universidad de Chile, 2019)En este proyecto de tesis, se propone una estrategia de control predictivo (MPC, por sus siglas en inglés) basada en el concepto de secuencia de conmutación óptima (OSS) recientemente introducido para convertidores de punto ...
-
(Universidad de Chile, 2016)Importar gas natural licuado (GNL) a través de contratos Take-or-Pay (ToP) para la generación de electricidad en sistemas hidrotérmicos es una tarea compleja ya que la demanda de gas es altamente incierta dada la variabilidad ...
-
(EDP Sciences, 2018)Context. Astrometry relies on the precise measurement of positions and motions of celestial objects. Driven by the ever-increasing accuracy of astrometric measurements, it is important to critically assess the maximum ...
-
(Wiley, 2020)In fluorescence microscopy imaging, the segmentation of adjacent cell membranes within cell aggregates, multicellular samples, tissue, organs, or whole organisms remains a challenging task. The lipid bilayer is a very thin ...
