    Assessing the benefits of a decentralized waterborne container transportation service from the perspective of a canal port
    (2023) Alias, Cyril; Felde, Jonas zum; Gründer, Dieter; Severin, Sven; Alarcón Olalla, Frank Eduardo
    For a modal shift from road to inland waterway transportation, a new transportation service in the West German canal network, which is located in the hinterland of the Belgian, Dutch, and German seaports and between their respective hinterland hubs, has been designed and examined. Therefore, the new concept is designed as a feeder shuttle between these hubs. However, the effect of the new service on the canal ports in the region was still to be proven. The performance of the concept is measured and evaluated in different scenarios with the help of discrete-event simulation. The example of the port of Osnabrück, Germany, is used to illustrate the case and to show the impact the new service has on the participating canal ports. Based on the findings, the configuration of the service can be finetuned before the involved vessel operators and canal port authorities can prepare the rollout.

    Electric mobility toward sustainable cities and road-freight logistics: A systematic review and future research directions
    (2023) Alarcón Olalla, Frank Eduardo; Mac Cawley Vergara, Alejandro Francisco; Sauma Santis, Enzo Enrique; Millennium Institute on Green Ammonia As Energy Vector (MIGA), Pontificia Universidad Católica de Chile
    The importance of electric vehicles (EVs) lies in the fact that they are seen as a key solution to the climate change problem. In the last decade, this topic has received significant interest from the scientific community, contributing to publications in different areas. However, the existing literature is fragmented, and efforts have not been made to categorize and analyze it from a freight logistics perspective. This work aims to fill this gap by presenting a systematic literature review (SLR) of the potential impacts of EVs on sustainable road-freight transport operations, including in urban areas. We reviewed 237 peer-reviewed articles for bibliometric and literature classification analysis, whereby 119 articles were subsequently studied for content analysis and research gaps related to sustainability approaches. The bibliometric analysis showed significant growth in the body of research in the past two years, reflected in the number of journal papers, authors, and references. In the literature and keywords analysis, we identified five main categories and research areas: economic and competitive aspects, city logistics, environmental sustainability, vehicle fleet operations, and infrastructure and technology. In addition, this paper revealed eight key research gaps for future research: multimodal integration, long-haul and heavy-duty truck approaches, emerging economies, business models, social factors, charging infrastructure inclusion, and fleet replacement policies. These findings can enlighten researchers and practitioners toward sustainable research and real-life applications of electromobility in freight logistics.

    Measuring the Performance Impact of a Decentralized Waterborne Container Transportation Service on Inland Waterway Hubs in Western Germany
    (IEEE, 2022) Alias, Cyril; zum Felde, Jonas; Alarcón Olalla, Frank Eduardo; Severin, S.
    In view of eroding market shares of inland waterway transportation, innovative waterborne transport service concepts and new business models are needed. In order to safeguard the successful adoption of the new IWT services, it is of utmost importance to prove their economic viability and present the individual gain for all parties and stakeholders involved. One of the parties involved are the inland waterway hubs that connect the new services to the existing service landscape. By examining the effects of the service on hubs and proving its viability, an important hurdle is taken on the way to real-world application.With the help of discrete-event simulation, the performance of the envisioned decentralized waterborne container transportation service can be examined. Numerous scenarios have been developed and examined in order to develop an understanding of the service under miscellaneous conditions. The scenario results can be used for a closer look at the performance results of the IWT hubs and a comparison with one another. By ensuring a good economic performance of the IWT hubs involved, the realization of the service concepts appears more likely.

    The competitiveness of electric trucks in multimodal networks. A case study of integration with inland waterways
    (2025) Alarcón Olalla, Frank Eduardo; Sauma Santis, Enzo Enrique; Cyril, Alias
    Crucial steps towards sustainable transportation include reducing road transport and transitioning to electric vehicles. Inland waterway transport (IWT) can reduce road transport but has not yet integrated battery-electric trucks (BETs) into its network. This study aims to address this gap by evaluating the competitiveness of heavy-duty BETs within a multimodal concept in the West German canal network. The total cost of ownership (TCO) methodology results indicate that BETs can be competitive with diesel trucks depending on the distance traveled and the ownership period. The baseline scenario suggests that BETs become a more economical option than diesel trucks for daily distances exceeding 234 km, assuming a 9-year ownership period. The economic impacts of various scenarios are evaluated, including subsidies, maintenance contracts, resale values, tolls, recharge times, and CO2 emissions. The purchase cost of the truck is the most significant cost for the electric option, while the fuel cost is the main cost for the diesel option. Furthermore, the results indicate that BETs emit 56 % less greenhouse gas (GHG) emissions than their diesel counterparts, and the decentralized IWT concept can decrease GHG emissions by 51 % through reduced road transport. The findings can provide decision-makers with a tool for efficiently allocating the type of truck to use according to their transport tasks.
