Designing an open-loop supply chain network for recyclable products: a case study

Recently, because of the recycling policies and environmental issues, the combination of forward and reverse logistics has attracted lots of attention to itself. The current paper presents a designed open-loop supply chain network to reuse the returned goods. To this aim, a mixed integer linear model is proposed that minimises the total cost. The proposed model determines the location of distribution centres, recycling centres, collection centres, disposal centres and also the quantity of the transferred product between levels. Finally, in order to investigate the effectiveness of the proposed model, it is implemented at one of Iranian Poly Ethylene Terephthalate (PET) product companies.
