摘要:

交通运输部门过度的温室气体排放导致公司转向可持续的供应链网络设计。在这项研究中,我们提出了一个新的双目标非线性制定多个库存组件集成到整个供应链网络的位置和路由决策。为了有效地解决所提出的模型,我们实现了一个精确的方法和四个进化算法的小型和大型的实例。大量的计算结果和灵敏度分析进行验证所提出的方法的效率,定量和定性。此外,我们还进行了统计分析,以调查不同解决方法之间是否存在任何统计学显著差异。

英文摘要:

Excessive greenhouse gas emissions from the transportation sector have led companies to move towards a sustainable supply chain network design. In this study we present a new bi-objective non-linear formulation where multiple inventory components are integrated into the location and routing decisions throughout the supply chain network. To efficiently solve the proposed model, we implement an exact method and four evolutionary algorithms for small and large-scale instances. Extensive computational results and sensitivity analysis are performed to validate the efficiency of the proposed approaches, both quantitatively and qualitatively. Besides, we run a statistical analysis to investigate whether there is any statistically significant difference between solution methods.
