By 2025 the Republic of Colombia aims to be an advisory member of the Antarctic Treaty System (ATS) and the installation of a scientific station is necessary to upscale the scientific capabilities. The aim of this paper is showing the results of the implementation of a Fuzzy TOPSIS algorithm for site selection of the Colombian Antarctic Scientific Station. A three-phase methodology was proposed, and the obtained results allowed to identify the optimum location for the station, considering key success factors and regulatory constraints.

Los aportes de la Investigación de Operaciones (IO) en el campo de la salud han sido ampliamente estudiados en la literatura científica desde la década de los 60, abarcando el soporte a la decisión en enfoques operacionales, tácticos y estratégicos. Se presenta un resumen del desarrollo histórico de la IO en el campo de la salud y se listan los principales modelos aplicados en los últimos años, identificando el principal enfoque utilizado, y el potencial aporte a la toma de decisiones en el campo de la salud.

Work study is an extensively used technique for examining the methods to carry out activities in a company and proposing actions for productivity improvement. This paper presents a work-study application to a fruit nectar process inside a food company using 5W1H and ECRS techniques. A critical analysis was conducted in three previously selected activities, according to its improvement potential. Results allowed optimizing distances along the process and improving ergonomic conditions for workers. Savings included a total distance of 10.2 m, two transportation activities and two delays activities per production cycle. Also, the standard time was determined in one of the prioritized activities. Our results demonstrated that work study techniques are tools suitable to be implemented in most economic sectors for productivity improvements. However, the technique itself will not be effective without a commitment from top-level management for implementing the corrective actions proposed.
