Abstract: To design appropriate integrated logistics networks structures for hybrid manufacturing/remanufacturing systems, a mixed integer nonlinear programming model for designing such networks was developed by considering the integration of various facilities and transportation combination of forward and reverse logistics in the network. According to the model, the number of various facilities, their locations and scales, and the allocation of the corresponding logistics flows could be decided upon, so as to maximize the net revenue over the operation period. A hybrid genetic algorithm with self-adaptive crossover and mutation was proposed to optimize the design. Finally, an example was presented to demonstrate the validity of the model and algorithm.
