This paper suggests the reverse logistics (RL) network which are composed of customers, collection centers, recovery centers, redistribution centers, and secondary markets. This RL network is formulated using a mixed integer programming (MIP) model and its objective is to minimize the total cost under considering various constraints such as unit transportation costs, fixed costs, and variable costs. The MIP model is implemented in the genetic algorithm (GA) approach. Two test problems with various sizes of collection centers, recovery centers, redistribution centers, and secondary markets are considered and they are solved using the GA approaches. A comparison between the GA approach and the other competing approaches has been done using some measures of performance. Finally, it has shown that the optimal solution of the GA approach is more efficient than those of other competing approaches.
