espanolEn esta investigacion se presenta un modelo de programacion lineal multiobjetivo para la logistica inversa del sector plastico de polipropileno. Para ello, se realizo una revision de los referentes teoricos relacionados con el proceso de recuperacion del plastico de polipropileno a partir de residuos solidos urbanos y los desperdicios de los procesos industriales. Seguidamente se definio un modelo de programacion lineal multiobjetivo el cual incorpora las variables y parametros identificados en el diseno del proceso de logistica inversa. Finalmente se hace un analisis comparativo de un caso de estudio para determinar el impacto del modelo en los resultados del programa de planeacion logistica. Se muestra un mejoramiento del 12,6% en los costos asociados al programa de planeacion. Al mismo tiempo se optimiza el Indice de Degradacion a la Procesabilidad lo que genera una buena calidad del polipropileno reciclado. EnglishA model of multi-objective linear programming for reverse logistics sector of plastic polypropylene is presented in this paper. For this, a review of the theoretical framework related to the recovery process of polypropylene plastic from municipal solid waste and waste of industrial processes was done. Next, a multiobjective linear programming model which incorporates the variables and parameters identified in the design of the reverse logistics process was defined. Finally, a comparative analysis of a case study is done to determine the impact of the model on the results of the program logistics planning. An improvement of 12.6% was found in the costs associated with the program planning. At the same time, the Degradation to Processability Index is optimized which generates good quality recycled polypropylene.
