| Abstract: | This paper formulates an inland cargo flow model that considers the additional costs incurred because of variability in shipment times at borders and seaports. Using the proposed model, five scenario analyses for cross-border haulage between Lao PDR and seaports in Thailand and Vietnam are carried out in order to assess the impact of improving border and seaport reliability. These scenario analyses show that improving shipment time variability at seaports has more impact on cost reduction compared to improving border reliability. As for seaport choice, both cases of seaport and border reliability indicate similar trends. Cargo volumes decrease at Laem Chabang seaport in Thailand and increase at Vietnamese seaports as reliability at each identified bottleneck is improved. |
