    Impacto del material reciclado en los inventarios de materias primas de una empresa manufacturera
    (2013-10-23) Salinas-López, G. A. (Guillermo Antonio); Victoria-Moreno, A. (Anthony); Osorio, J.C. (Juan Carlos)
    In this paper, a system dynamics model is designed. This model, together with some management indicators is used to measure the impact of recycled material in an industry. This, in order to provide best elements in decision making process related to the management of raw materials stocks. For this purpose, a review of the main elements that influence the production plan of a business case study is performed. Thus, a characterization of the industry and subsequent configuration of the structure and relationships of the system is obtained, in order to model and simulate using the software Vensim DSS. From these simulations, a review and analysis of the system behavior, as well as variations proposed, in different scenarios and changes in relevant parameters, is executed. At the end, a model that illustrates the behavior of inventory levels of different types of materials as well as the values of some logistics and energy indicators is obtained, revealing the important work ahead in recycling on the region of Valle del Cauca, Colombia.

    El pensamiento sistémico como herramienta metodológica para la resolución de problemas
    (2014-05-14) Liévano-Martínez, F. (Federico); Londoño-Salazar, J. E. (Jesús Enrique)
    This article presents a theoretical approach that shows the systems thinking as a methodological tool for the analysis of problems. We discuss how the technique is widely used in different scientific areas, nevertheless in several times is unknown the systems thinking practical tools in operative’s scopes. The theoretical approach proposed, depicts some systems thinking tools that are used for the comprehension, modeling and resolution of complex problems.
