DE LA HOZ, Efraín; VELEZ, Jorge  and  LOPEZ, Ludys. Multiobjective Linear Programming Model for Reverse Logistics in the Polypropylene Plastics Industry. Inf. tecnol. [online]. 2017, vol.28, n.5, pp.31-36. ISSN 0718-0764.

A 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.

Keywords : reverse logistics; degradation index; solid waste; plastic; linear multiobjective programming.
