Introduction
Intermodal transport, recognized as a cornerstone in the fabric of contemporary logistics, offers a versatile and efficient mechanism for the uninterrupted flow of goods through varied transportation modes (Acero et al., 2021).Central to this complex network are the intermodal terminals, serving as critical junctures where cargo seamlessly transitions across road, rail, and sea modalities.The value of these terminals is primarily in their function as dynamic hubs, orchestrating the smooth transfer of shipments between disparate transport methods, thus enhancing the overall supply chain efficiency (Bouchery et al., 2014).The provision of centralized points for cargo consolidation and deconsolidation, coupled with the facilitation of modal shifts at these terminals, contributes significantly to reduced transit times, increased flexibility, and cost efficiencies.As integral components of the intermodal network, the role of these terminals in fostering operational efficiency and supply chain fluidity is indispensable.
The imperative of modernizing intermodal terminals is underscored in the context of advancing the efficiency and resilience of current supply chain networks (Makarova et al., 2019).This modernization encompasses the adoption of cutting-edge technologies and methodologies, tailored to meet the evolving requisites of logistics operations.The implementation of I4.0 technologies, characterized by their emphasis on connectivity, automation, and data-centric decision-making, emerges as a pivotal strategy in this transformation.The integration of these technologies within intermodal terminals is instrumental in streamlining operations, optimizing resource allocation, and facilitating a dynamic response to fluctuating demands (Vida et al., 2023).Such advancements yield marked improvements in throughput, minimize delays, and amplify overall operational efficacy.The assimilation of I4.0 technologies in the modernization of intermodal terminals is congruent with the broader objective of cultivating agile, responsive, and technologically sophisticated logistics ecosystems, adept at navigating the complexities of modern supply chain dynamics.
The primary objective of this research is the systematic identification and assessment of I4.0 technologies, focusing on those with the potential to significantly enhance the operational efficiency of intermodal terminals.This entails a meticulous process to discern and evaluate technologies that not only promise substantial operational improvements but are also critically relevant for these terminals.By employing a structured methodology, the study seeks to isolate I4.0 technologies that demonstrate the highest potential in optimizing terminal operations, alleviating bottlenecks, and contributing markedly to overall terminal efficiency.Consequently, the research endeavors to furnish logistics industry stakeholders with insightful, strategic guidance for modernizing intermodal terminals and augmenting their operational effectiveness.

Literature Review
The body of existing literature pertaining to intermodal transport and terminal efficiency is characterized by a diversity of research domains.Investigations in the field of intermodal transport predominantly focus on operational dynamics, as highlighted by Priemus & Konings (2017), with a particular emphasis on the crucial role of terminals in facilitating efficient cargo movement across various modes, as delineated by Tadić et al. (2019).The exploration of terminal optimization strategies is extensively covered (Muravev et al., 2021), alongside analyses of the impacts arising from modal shift initiatives on supply chain performance (Colicchia et al., 2017) and the economic ramifications of enhanced logistics operations within these terminals (Protic et al., 2019).
A significant facet of the literature concentrates on the modernization of intermodal terminals.Winkelhaus & Grosse (2019) underscore the necessity of adopting advanced technologies and methodologies in response to the evolving demands of logistics operations.The discourse extensively deliberates on the implementation of I4.0 technologies, including the IoT, Artificial and Ambient Intelligence, and Autonomous and Automated Guided Vehicles (Barreto et al., 2017).These technologies are examined for their capacity to revolutionize operations, optimize resource utilization, and dynamically adapt to changing requirements.The outcome of I4.0 implementation, as evidenced by improved throughput, diminished delays, and enhanced overall operational efficiency, is scrutinized (Cañas et al., 2021).
Furthermore, research underscores the strategic imperative of modernizing intermodal terminals to align with overarching logistics goals (Hu et al., 2019).The literature advocates for the creation of agile, responsive, and technologically advanced logistics ecosystems, equipped to navigate the complexities of contemporary supply chain dynamics (Chowdhary, 2022).This research contributes to this scholarly conversation by systematically identifying and evaluating potential I4.0 technologies, thereby providing stakeholders with practical insights for enhancing intermodal terminal efficacy.The employment of MCDM methods is pivotal in this context, facilitating the ranking and selection of I4.0 technologies.This study utilizes a hybrid model, integrating the BWM and ADAM, to ensure a comprehensive and efficacious evaluation.
The BWM, conceptualized by Rezaei (2015), serves as an evaluative tool for comparing alternatives across a variety of criteria.As a pairwise comparison technique, BWM involves a systematic assessment process wherein a decision maker evaluates each alternative against each criterion, identifying the best and worst options for each.Criteria are then assigned weights according to their significance, and scores for alternatives are calculated accordingly.Despite the subjective nature of judgments inherent in this method, BWM is noted for its flexibility, suitability for handling multiple criteria with a reduced need for pairwise comparisons, and ease of use (Rezaei, 2015).It has been recognized for its superior consistency, accuracy, and compliance in comparison to other MCDM methods (Guo & Zhao, 2017).Recent applications of BWM include the classification and ranking of key factors and external influences in I4.0 technology adoption (El Baz et al., 2022), site selection for power stations (Besharati Fard et al., 2022), prioritization of key success factors in sustainable Lean Six Sigma implementation (Swarnakar et al., 2022), sustainability assessments in urban transportation (Yucesan et al., 2024), and supply chain disruption evaluations (Ali et al., 2023).This study employs BWM for determining criteria weights, leveraging these advantages.
Conversely, the ADAM method, introduced by Krstić et al. (2023a), facilitates alternative rankings by quantifying the aggregate dimensions of complex polyhedra, offering an intuitive graphical representation.ADAM is known for minimizing rank reversal risks, maintaining stability across a range of criteria, and aligning with other MCDM methods (Krstić et al., 2023b).Despite its relative novelty, both the conventional and fuzzy versions of ADAM have proven effective in various contexts, such as in selecting city logistics concepts (Kovač et al., 2023), ranking circularity-enhancing strategies (Agnusdei et al., 2023), and choosing logistics service providers (Krstić & Tadić, 2023).
A significant research gap exists in the identification and selection of the most suitable I4.0 technologies for intermodal terminals.There is a notable absence of a tailored MCDM model specifically designed for their systematic ranking.The literature lacks a comprehensive framework for the evaluation and prioritization of these technologies within the context of intermodal terminals.This gap impedes the formulation of strategic modernization plans.Bridging this gap is pivotal for establishing an effective approach to select and implement I4.0 technologies, thereby enhancing the overall efficacy of intermodal terminals in the realm of contemporary logistics.

Methodology
The methodology of this study encompasses the utilization of a MCDM model, which entails the delineation of the problem structure through the specification of sets of alternatives and criteria.Integral to this process is the establishment of an evaluation scale, typically a nine-point scale, for the assessment of alternatives, as detailed in Table 1.

Linguistic Evaluation
Abbreviation Numerical Value "None" "N" 1 "Very Low" "VL" 2 "Low" "L" 3 "Fairly Low" "FL" 4 "Medium" "M" 5 "Fairly High" "FH" 6 "High" "H" 7 "Very High" "VH" 8 "Extremely High" "EH" 9 The BWM is employed to obtain criteria weights.This process includes identifying the best and worst criteria, determining preferences, and calculating weights to ensure consistency.It implies the following optimization problem: where ξ serves as a measure of the consistency in the comparison (the lower the better), wj indicates the weight of criterion j, m is the total number of criteria, wb and ww are the weights of the best and the worst criteria, respectively; ubj is the preference of the best criterion over criterion j, and ujw is the preference of criterion j over the worst criterion.
The ADAM method is then applied to evaluate and rank alternatives.This involves creating a decision matrix based on evaluations of alternatives (eij) for each criterion.
where, i indicates the alternative and n is the total number of alternatives.
The matrix is sorted by the importance of criteria, and normalized values are derived based on benefit (B) and cost (C) criteria.
Reference (Rij) and weighted reference points (Pij) in a three-dimensional space are calculated, forming a complex polyhedron.Coordinates of these points are obtained as follows: sin , 1, , ; 1, , Volumes of these polyhedra, computed using pyramid volumes, are used to rank alternatives.The higher the volume, the better the alternative is considered.
