    (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.

    Selección de proveedores usando el despliegue de la función de calidad difusa
    (2013-11-18) Osorio, J.C. (Juan Carlos); Arango, D. C. (Diana Carolina); Ruales, C. E. (Christian Ernesto)
    This paper presents a multicriteria methodology for supplier selection framed in a certification process with the approach of ISO 9001:2000 standard, using fuzzy QFD as a tool for decision making. The model takes into account the needs and expectations of the buyer and considers as a fundamental element of the process the knowledge that the company has about has both about the materials and processes, and candidate suppliers to be selected. This model was applied in a manufacturing company in Colombia.
