Abstract: To set up an appropriate integrated logistics network for hybrid manufacturing/ remanufacturing systems, an optimization model for designing such a network was established based on mixed integer linear programming approach.In this model, the present worth method was used to consider the time value of operational costs over a planning horizon.According to the model, the numbers and locations of distribution centers and collection centers, and the allocation of the corresponding goods flows in the network can be decided upon to minimize the sum of the investment costs and the present equivalent of the future operational costs over the planning horizon.Finally, the validity of the model was demonstrated by a numerical example and a sensitivity analysis of the model was performed.
