Resumen Este documento evalúa el impacto de incluir acciones en el portafolio de reservas internacionales administrado por el banco central de Colombia (Banco de la República). El objetivo es realizar una propuesta de inversión con relación a las acciones que sea acorde a las políticas de...

Resumen Las áreas marinas protegidas son reconocidas en la actualidad como una alternativa de conservación de los ecosistemas marinos. Aunque la figura de protección reduce el área disponible para la actividad pesquera, se ha documentado que la misma puede convertirse en una fuente de...

In this paper we develop a framework to analyze stochastic dynamic optimization problems in discrete time. We obtain new results about the existence and uniqueness of solutions to the Bellman equation through a notion of Banach contractions that generalizes known results for Banach and local...

The integrated management of solid waste at the household level involves adequate collection logistics for recovery by waste collectors. The objective of this study was to optimize the route for access to waste at strategic points in the city of Manizales (Colombia), in addition to analyzing the...

Linking the statistic and the machine learning literature, we provide new general results on the convergence of stochastic approximation schemes and inexact Newton methods. Building on these results, we put forward a new optimization scheme that we call generalized inexact Newton method (GINM)....

In developed countries, day surgery has been used as a significant tool of efficiency increase in the health care system over the last few decades. However, its development is not sufficient in the Slovak conditions in spite of the support of the Ministry of Health of the Slovak Republic. Its...

In the presented paper we develop model of apportionment of cost generated by variability and mean value of flows from (to) shared services centre. It can be either cash pool or distribution centre, or even some kind of customer service centre. The apportionment formula for the cost of capacity...

Long-term throughput, as a key performance indicator of a stochastic flow line, is affected by numerous parameters describing the features of the flow line, such as processing time and buffer size. Fast and accurate evaluation methods for a given set of values for those parameters are a...

Increasing renewable electricity generation and the electrification of industry, mobility, and heating through sector coupling pose significant challenges to grid operators in maintaining secure and reliable system operations. Demand-side sector coupling applications increase electricity demands...
