TL;DR
This paper addresses decarbonizing freight networks through intermodal, multimodal, and synchromodal transportation from an operations research perspective. It conducts a systematic literature review of studies from 2010 to 2024, noting a notable surge in decarbonization-focused work after 2018 driven by regulation and technology. The integrated analysis categorizes work by modality mix, decision levels, emissions considerations, and OR techniques, highlighting trends such as the rise of synchromodality, stochastic and multiobjective formulations, and policy-oriented models using carbon pricing and life-cycle assessment. It identifies gaps in multistage stochastic modeling, terminal-operation dynamics, and emerging technologies like AI/RL and blockchain for collaboration and resilience, providing a roadmap for future research.
Abstract
This paper reviews intermodal transportation systems and their role in decarbonizing freight networks from an operations research perspective, analyzing over a decade of studies (2010-2024). We present a chronological analysis of the literature, illustrating how the field evolved over time while highlighting the emergence of new research avenues. We observe a significant increase in research addressing decarbonization since 2018, driven by regulatory pressures and technological advancements. Our integrated analysis is organized around three themes: a) modality, b) sustainability, and c) solution techniques. Key recommendations include the development of multistage stochastic models to better manage uncertainties and disruptions within intermodal transportation systems. Further research could leverage innovative technologies like machine learning and blockchain to improve decision-making and resource use through stakeholder collaboration. Life cycle assessment models are also suggested to better understand emissions across transportation stages and support the transition to alternative energy sources.
