最近的美国商品流量调查数据表明，危险物质（HAZMAT）的运输通常涉及多种模式，特别是长途运输。然而，关于危险品在多式联运网络中的位置和路线的研究还不多。大多数现有的危险品位置和路线研究只集中在单一模式（公路或铁路）。针对目前国内外对危险物品多式联运位置和路线研究的不足，以及对危险物品多式联运的需求日益增加的现状，提出了一种同时优化转运堆场位置和运输路线的危险物品多式联运模型。将所建立的模型应用于两个不同网络规模的案例研究，以验证其适用性。对研究结果进行了分析，并对今后的研究提出了建议。
The recent US Commodity Flow Survey data suggest that transporting hazardous materials (HAZMAT) often involves multiple modes, especially for long-distance transportation. However, not much research has been conducted on HAZMAT location and routing on a multimodal transportation network. Most existing HAZMAT location and routing studies focus exclusively on single mode (either highways or railways). Motivated by the lack of research on multimodal HAZMAT location and routing and the fact that there is an increasing demand for it, this research proposes a multimodal HAZMAT model that simultaneously optimizes the locations of transfer yards and transportation routes. The developed model is applied to two case studies of different network sizes to demonstrate its applicability. The results are analyzed and suggestions for future research are provided.
