Reverse logistics network design for product recovery and remanufacturing

Abstract

• A mathematical model for the network design of multi-echelon reverse logistics is developed. • A hybrid genetic algorithm is proposed to solve the problem. • The amount of remanufactured products depends on the critical and the most valuable modules. • The model results produce less CO 2 and reduce the environmental impact. • The results show the proposed model performs better than current reverse logistics operating in the real city. Due to environmental concerns, reverse logistics now is becoming an important strategy to increase customer satisfaction. This research develops a generic mixed integer nonlinear programming model (MINLP) for reverse logistics network design. This is a multi-echelon reverse logistics model. It maximizes total profit by handling products returned for repair, remanufacturing, recycling, reuse, or incineration/landfill. A hybrid genetic algorithm (GA) is proposed to solve the problem. The designed model is validated and tested by using a real-life example of recycling bulk waste in Taoyuan City, Taiwan. Sensitivity analyses are conducted on various parameters to illustrate the capabilities of the proposed model. Post-optimality analysis and comparison show that the proposed model performs better than current reverse logistic operations and the proposed hybrid GA demonstrates the efficiency of solving the complex reverse logistics problem.
