Abstract: Green logistics is of importance for environmental protection, saving resources and carrying out the strategy of sustainable development. When designing logistics networks, not only cost, environmental impact of logistics activities also needs to be considered in green logistic. So, how to get a balance between logistics cost and environmental quality is a key problem. In this paper, a decision framework and conception model for designing logistics network is proposed. By taking logistics cost and environmental quality as optimization objectives, the efficiency boundary through multi-objective optimization method can be attained. The properties of efficiency boundary are also analyzed. At last,an example is used to illustrate the findings. It is verified that the proposed method is an effective decision-making tool for enterprise to implement green logistics.

Key words: green logistics, network design, efficiency boundary, multi-objective decision
