SALINAS LOPEZ, Guillermo Antonio; VICTORIA MORENO, Anthony  e  OSORIO GOMEZ, Juan Carlos. IMPACT OF RECYCLED MATERIAL ON INVENTORIES OF RAW MATERIALS OF A MANUFACTURING COMPANY. Rev.EIA.Esc.Ing.Antioq [online]. 2013, n.19, pp.91-101. ISSN 1794-1237.

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.

Palavras-chave : system dynamics; simulation; reverse logistics; raw materials.
