With material cycles becoming more international, the design of international reverse logistics (IRL) networks has also become increasingly important, especially in island nations such as Japan, where maritime transportation plays a significant role. Nevertheless, few studies relate to IRL design, with most existing research focusing on economic efficiency. However, IRL networks’ resilience is equally or even more important than the typical logistics network design. As developed countries—including Japan—are usually exporters of recyclables, IRL malfunctions can cause waste or recyclables to accumulate in these countries, leading to inefficient waste management practices, such as landfilling. As IRL networks are characterized by low transportation rates and other uncertainties, they must be able to absorb this volatility and function despite any disruptions. This study utilizes a Japanese case study of IRL networks to establish a model and design a resilient, efficient IRL network using a cost-minimization model with resilience constraints. Our model reveals that expanding ports in a remote area with inexpensive storage costs increases economies of scale while contributing to IRL networks’ resilience by forming hubs.

设计用于物料循环的弹性国际逆向物流网络:日本案例研究

随着物质周期变得越来越国际化,国际逆向物流(IRL)网络的设计也变得越来越重要,尤其是在日本等岛国中,海上运输起着重要作用。但是,很少有研究与IRL设计有关,而大多数现有研究都集中在经济效率上。但是,IRL网络的弹性比典型的物流网络设计同等甚至重要。由于发达国家(包括日本)通常是可回收产品的出口商,IRL故障会导致这些国家的废物或可回收物积聚,从而导致废物管理实践效率低下,例如填埋。由于IRL网络的特点是运输速率低和其他不确定性,他们必须能够吸收这种波动性和功能,即使受到任何干扰。这项研究利用日本的IRL网络案例研究来建立模型,并使用具有弹性约束的成本最小化模型设计一个弹性,高效的IRL网络。我们的模型表明,以低廉的存储成本在偏远地区扩展端口可提高规模经济,同时通过形成枢纽来促进IRL网络的弹性。
