espanolEste trabajo presenta un modelo multiobjetivo no lineal entero mixto (MINLP) para el diseno sostenible de cadenas de suministro para el reciclaje de varios materiales. En el se integran objetivos economicos y medioambientales para soportar la toma de decisiones estrategicas y tacticas tales como la localizacion de instalaciones, el diseno de los flujos materiales y la seleccion de medios de transporte. La evaluacion del impacto medioambiental se realiza a traves de la metodologia de Analisis del Ciclo de Vida (LCA) utilizando el Ecoindicador 99. Se modelo un caso de estudio para la cadena de reciclaje de dos tipos de plastico, utilizando el metodo de las restricciones para obtener la frontera de Pareto. En el desarrollo del caso se mostraron indicadores que permiten evaluar las soluciones encontradas y asi facilitar el proceso de toma de decisiones. EnglishThis paper presents a multi-objective mixed integer non-linear problem (MINLP) to design the sustainable supply chain for recycling several products. This model integrates economical and ecological objectives to support strategic and tactical decisions such as facility location, material flow design and transport selection. The environmental impact is assessed through the Life Cycle Assessment (LCA) methodology using the Eco-indicator 99. A case study to design a supply chain for recycling two kinds ofplastic was modeled, the constrain method was used to build the Pareto curve. In the case study were shown a set of indicators to assess the solutions for better supporting of decision-making process.
