Modelling Multi-layer Multi-product Reverse ...

This paper presents a mathematical programming model which minimizes the total cost of multi-layer multi-product reverse supply chain. The total costs of reverse supply chain include transportation, fixed opening, operation, maintenance and remanufacturing costs of centers. To validate the mathematical model, a numerical example is exemplified using Lingo 9 software and the results are illustrated to gain a better insight into the proposed model. In addition, a sensitivity analysis of the proposed model is also presented.
