Eco-Efficient Based Logistics Network Design in Hybrid Manufacturing/Remanufacturing System Under Low-Carbon Restriction

Abstract

In this paper the question of trading off the economic and environmentaleffects embodied in eco-efficiency in the hybridmanufacturing/remanufacturing logistics network design in the context oflow-carbon economy is examined. A multi-objective mixed integer linearprogramming model to find the optimal facility locations and materialsflow allocation is established. In the objective function, three minimumtargets are set: economic cost, CO2 emission and waste generation.Through an iterative algorithm, the Pareto Frontier of the problem isobtained. The results of numeric study show that in order to achieve aPareto improvement over an original system, three of the critical ratesshould be increased. Also, to meet the need of low-carbon dioxide, aniso-CO2 emission curve in which decision makers have a series of optimalchoices with the same CO2 emission but different cost and wastegeneration is plotted. Each choice may have different network design butall of these are Pareto optimal solutions, which provide a comprehensiveevaluation of both economics and ecology for the decision making.
