绿色物流网络系统建模与效率边界分析

绿色物流对于我国保护环境、节约资源和实施可持续发展战略具有重要的意义。绿色物流要求在进行物流网络系统设计时不能只考虑成本,还要考虑物流活动对于环境的影响。因此如何平衡物流成本和环境质量是一个关键问题。本文提出了绿色物流网络设计步骤和模型,将环境质量和物流成本作为优化的目标,利用多目标优化方法获得物流成本和环境质量之间的效率边界。通过分析效率边界的性质,指出了效率边界的作用。最后通过实例计算对影响效率边界的参数进行了分析,能为有效的实施绿色物流提供决策工具。

Models and Efficiency Boundary Analysis of Green Logistics Networks

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.
