Abstract: The extended model for logistics network integrating remanufacturing and manufacturing system is studied, and an extended location-allocation model is presented. The characteristics of the extended model are as follows: the network structure is a closed loop network; the allocation of manufactured and remanufactured products that can't be replaced with each other is comprehensively considered; and the locations of potential manufacturing/remanufacturing facilities, warehouses and disassembly centers are addressed.
