La transformation digitale des chaînes logistiques en Afrique : déterminants, freins et effets

Yassin Selouani, Ikram El Hachimi, Driss Ouslimane

Le management de la chaîne logistique connaît aujourd'hui de profondes mutations, dans lesquelles la transformation digitale s'impose comme un levier essentiel pour améliorer la traçabilité, renforcer la résilience et accroître la compétitivité des organisations. Si cette évolution est largement documentée dans les économies développées, les connaissances restent encore limitées en Afrique, où les contextes infrastructurels, institutionnels et socio-économiques présentent des spécificités importantes. Cette étude propose une revue systématique de la littérature afin de dresser un état des lieux des recherches consacrées à la transformation digitale des chaînes logistiques sur le continent. En suivant le protocole PRISMA, une recherche menée dans sept sources de recherche documentaire a permis de retenir 56 études parmi 742 références initialement recensées. Les résultats montrent un champ de recherche encore émergent, principalement centré sur l'Afrique du Sud, le Nigeria, le Ghana et le Kenya, ainsi que sur les secteurs agricole et pharmaceutique. La blockchain et l'Internet des objets dominent les travaux, tandis que l'intelligence artificielle et le big data demeurent encore peu mobilisés. Malgré une accélération de l'adoption sous l'effet de la pression concurrentielle et de la COVID-19, des obstacles persistants, telles que l’insuffisance des infrastructures, les coûts élevés, le déficit de compétences et la faiblesse des cadres réglementaires, limitent les bénéfices attendus. Cette étude fournit ainsi une synthèse structurée en langue française d’un corpus principalement anglophone et met en évidence plusieurs pistes pour la recherche et les politiques de digitalisation des chaînes logistiques africaines.

A systematic literature review on Web3 applications in trucking logistics: Impacts and emerging trends in logistics 5.0

Daniel Calé, João C. Ferreira, Ana Mafalda Madureira, Carlos Coutinho

Web3 technologies, representing the next generation of a decentralised and user-centric Internet, offer innovative solutions to enhance adaptability, sustainability, and resilience in logistics systems aligned with the principles of Logistics 5.0. This study conducts a Systematic Literature Review (SLR) following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology, analysing peer-reviewed journal articles published between 2018 and 2024 and retrieved from Scopus, Web of Science Core Collection, IEEE Xplore, and ACM Digital Library. The review specifically focuses on trucking logistics, a sector characterised by high fossil-fuel dependency, operational fragmentation, and significant environmental impact. The findings reveal that Artificial Intelligence and Internet of Things technologies dominate current implementations, mainly supporting fleet management, route optimisation, accident prevention, and risk assessment. In contrast, blockchain applications remain limited, and metaverse-based solutions are largely exploratory and confined to training scenarios. Key research gaps include the scarcity of integrated Web3 solutions, the limited consideration of human-centric Logistics 5.0 dimensions, and the lack of large-scale empirical validation in real-world trucking operations. Based on the analysis, this paper proposes a conceptual framework that maps Web3 technologies to trucking logistics areas, investment priorities, and Logistics 5.0 objectives, offering actionable guidance for Logistics Service Providers transitioning from Logistics 4.0 to Logistics 5.0.

An Evaluation of EVM-Compatible Blockchain Platforms for Trade Finance

Asif Ahmad Bhat, Rizal Mohd Nor, Md Amiruzzaman, Md. Rajibul Islam · 5 authors

Blockchain, such as Bitcoin and Ethereum, has received significant attention and widespread usage in recent years. However, blockchain scalability has emerged as a challenging issue. This article explores the existing scalability options for blockchain, which can be categorized into two groups: first layer solutions and second layer solutions. First layer solutions involve network modifications like altering block size, while second layer solutions encompass techniques applied outside of the blockchain. Ethereum, the second largest blockchain, utilizes the Ethereum Virtual Machine (EVM) for executing smart contracts on the blockchain. Currently, there are several EVM-compatible blockchains with noticeable differences. In this study, we evaluated multiple platforms for conducting business processes in trade finance. We considered both Layer 1 and Layer 2 blockchain solutions and examined variations in cost and performance (speed). Based on the evidence gathered in this study, we provide recommendations for system designers to consider when selecting a blockchain platform.

Innovations, Technologies, and the Economics of Last‐Mile Operations: A Call for Research in Operations Management

Niels Agatz, Jan C. Fransoo, Elliot Rabinovich, Rui Sousa

Last mile operations (LMO), the processes involved in the critical last stage of delivering goods and services, have widespread relevance across major sectors of the economy, including retail, food services, healthcare, humanitarian services, energy distribution, telecommunications, public services, and others. These operations account for a significant portion of the costs, jobs, and economic output in these sectors. Global economic output involving last mile deliveries alone, for instance, is valued at $165 billion per year and is growing at about 10% per year (InsightAce Analytic 2024). Recent decades have witnessed an acceleration in the rate of evolution of LMO (Agatz et al. 2024; Boutilier and Chan 2022; Boyer and Hult 2005; Dreischerf and Buijs 2022; He and Goh 2022; Lyu and Teo 2022). Technology-driven innovations have catalyzed profound changes in the planning, design, and execution of LMO, with significant implications for the economics of these operations. Extending the last mile to the final user has increased convenience, accessibility, and reliability. Zipline, for example, has introduced drones to safely deliver lifesaving products in remote communities (Ackerman and Koziol 2019). An increasing number of pharmacies in Europe and Africa have been equipped with smart lockers to allow 24/7 access to critical medicines (Gobir et al. 2024). Some innovations leveraging platforms based on smartphone apps have given small corner stores in neighborhoods in cities across Latin America the means to sell and deliver daily groceries and other household staples to local residents (Escamilla et al. 2021). Other innovations, leveraging artificial intelligence, have found applications in vehicle routing tools and warehouse and fulfillment automation (such as Ocado's system (Mason 2019)), track-and-trace systems that provide real-time communications and visibility into delivery processes (such as Instacart and Uber Eats), anticipatory shipping algorithms to move inventories to specific areas ahead of realized demand (Chen and Graves 2021), and integration tools with third-party services (successfully deployed by ClickPost and ShipEngine). However, considerable challenges remain. For example, because of short time frames and high delivery volumes to many dispersed locations, LMO have little room for human error. Yet, since many firms tend to tap into low-skilled, temporary, or crowdsourced labor to provide these services, there is high variability in performance and worker availability. LMO are also expensive, due in part to rising labor costs, delivery failures, more demanding customers, and vehicle and parking restrictions. Although academic research in LMO has a long tradition in Operations Research (see e.g., Agatz et al. (2011), Otto et al. (2018), Boysen et al. (2019) and Reed et al. (2022)), LMO have barely been considered as an operations problem that requires process understanding and management within a sociotechnical system. The need for this is apparent, as increasing evidence points to managerial, economic, and sociotechnical challenges as major determinants of LMO success. Delivery workers have been noted to largely ignore the recommendations by routing algorithms in urban settings (Liu et al. (2023)); working conditions are an increasing societal and corporate concern; and customer experiences are less than satisfactory in many cases. Further, LMO are associated with negative externalities such as emissions, traffic congestion, and the abuse of public parking space. Operational costs are also very high—often up to a point where LMO are loss-making, such as in grocery home delivery. And, while there have been extensive technological innovations, many seem to fail in scaling at large, which could potentially be due to a poor understanding of the LMO from a process perspective. We need new research to better understand these challenges, as well as to propose new operational practices and business models based on the application of recent innovations. Such research requires a broadening of the phenomenological and theoretical scope of LMO research beyond traditional work in Operations Research. Theories on innovation applied to Operations Management can offer a valuable foundation to study research questions surrounding the scalability of technologies to support new business models in the last mile (Arthur 1994). Similarly, theoretical models examining technology, productivity, and employment can provide a foundation to understand how innovations can change the nature of work in last-mile settings (Autor et al. 2003; Autor 2015). Additional opportunities also exist to use transaction and information cost theories to understand how technological innovations may change organizational boundaries and the nature of organizations in the last mile (Afuah 2003). This confluence of innovations in the field, the multidimensional phenomena that determine performance, and the perspectives from theories from the operations management field provide an opportunity to shape a research program in LMO that will benefit from the Operations Management academic community. This was one of the main goals of our call for papers for the special issue on “Innovations, Technologies, and the Economics of Last-Mile Operations.” Another objective of this special issue was to formalize a research agenda and offer future directions for research to advance our understanding of LMO. To that end, in Section 2, we delve deeper into these operations, their functionalities, distinctive features, and challenges in the context of Operations Management. Then, in Section 3, we expand on research opportunities to tackle the most pressing challenges in LMO and identify knowledge gaps in Operations Management to be addressed in this endeavor. We close in Section 4 with conclusions, recommendations, and potential initiatives to build on the momentum created so far and further advance LMO as a knowledge area within Operations Management. In doing so, we introduce the several papers in the special issue as exemplars of research that can be done in the LMO domain. LMO are made of processes triggered by an agent (e.g., consumer, user, patient, worker, organization) that enable the provision of a service to this agent at the agent's selected location and time (or time period). LMO involve interactions with the agent—who participates in the process and co-creates value—and, by definition, comprise different service processes (Sampson and Froehle 2006). These processes are triggered by an agent's request for service and include the preparation and movement of goods and/or tangible resources (people, equipment) required for providing the service to the agent's selected location at the agent's selected time. A key trait of LMO is the fact that agents select the location and time of the provision of the service and that the provision of the service requires at least in part co-location with the agent. We submit that LMO can be classified into two main categories that differ significantly in the nature and extent of the associated customer co-creation activities (Sampson and Froehle 2006): goods-focused and agent-focused. Goods-focused LMO entails the provision of agent access to goods at a selected location and time, involving the preparation and movement of goods (e.g., groceries, meals) and resources (e.g., delivery vans, delivery people) to that location. A typical example would be e-commerce deliveries to consumer homes. Agent inputs are limited, primarily including information about the required goods (product selection and quantities) and delivery (time and location), as well as engaging in minor interactions with the provider during goods reception. The core value added is the movement of the goods to the agent's selected location and time. Goods-focused LMO correspond to “delivery services” and have received most research attention. Agent-focused LMO entail the provision of more general services to an agent at a selected location and time, involving the preparation and movement of service provision resources (e.g., people, equipment, inventory) to that location. A typical example would be performing repairs of equipment owned by the agent at its selected location, involving the movement of technicians, tools, and inventory (spare parts) to the agent's location. Another example would be an emergency ambulance service, which involves the movement of equipment (vehicle, medical instruments), medical staff, and inventory (medical supplies) to the agent's location. Agent inputs are substantial, including information about the required service, service delivery time and location, and agent's resources, as well as engaging in relevant service co-creation activities at the agent's location. The core value added is the transformation of the agent's inputs (e.g., agent-owned equipment, the agent self). Typically, the level of customization and agent co-creation increases from goods-focused to service-focused LMOs, while the transaction volumes decrease. LMO processes are characterized by a set of distinctive features that raise unique challenges for the management of operations. Based on our conceptualization of LMO and extant literature, we summarize LMO's distinctive features and associated challenges in Table 1. The remainder of the editorial will discuss LMO against this framework and address in more detail several of the distinctive features and challenges. The distinctiveness of LMO processes, their pervasiveness and widespread economic relevance, and the managerial challenges that remain unaddressed jointly motivate the development of a specific research program for LMO within the field of Operations Management. Need to cover very diverse geographical areas, with specific challenges: Reliance on a large number of independent resources (including subcontractors, crowdsourced labor, inventory, contracted or rented equipment, third-party platforms) has the following implications: The features and challenges presented in Section 2 provide a framework for the development of new LMO research that can broaden the scope of LMO subject knowledge, as well as strengthen the theoretical foundations supporting LMO research. This framework also serves as a reference for new research to inform about new technologies and business models in LMO and their implementation and execution. The remainder of this section expands on these research directions. Research on LMO has concentrated on goods-focused LMO, in particular the delivery of goods from a transportation hub or inventory location to an end consumer. As discussed in Section 2, we propose a conceptualization of LMO to include LMO, which also LMO with a of and the of agent a diverse set of such as and of goods and services, also organizational in with we to expand research to a set of LMO. more be given to LMO. services are in this to to and such as vehicle and services at Another area in point is the of can request of products local In this a of goods-focused and of products need to be to and more research is involving LMO.

Smart Transport Infrastructure Maintenance: A Smart-Contract Blockchain Approach

Fatjon Seraj

Infrastructure maintenance is inherently complex, especially for widely dispersed transport systems like roads and railroads. Maintaining this infrastructure involves multiple partners working together to ensure safe, efficient upkeep that meets technical and safety standards, with timely materials and budget adherence. Traditionally, these requirements are managed on paper, with each contract step checked manually. Smart contracts, based on blockchain distributed ledger technology, offer a new approach. Distributed ledgers facilitate secure, transparent transactions, enabling decentralized agreements where contract terms automatically execute when conditions are met. Beyond financial transactions, blockchains can track complex agreements, recording each stage of contract fulfillment between multiple parties. A smart contract is a set of coded rules stored on the blockchain that automatically executes each term upon meeting specified conditions. In infrastructure maintenance, this enables end-to-end automation-from contractor assignment to maintenance completion. Using an immutable, decentralized record, contract terms and statuses are transparent to all parties, enhancing trust and efficiency. Creating smart contracts for infrastructure requires a comprehensive understanding of procedural workflows to foresee all requirements and liabilities. This workflow includes continuous infrastructure monitoring through a dynamic, data-driven maintenance model that triggers necessary actions. Modern process mining can develop a resilient Maintenance Process Model, helping Operations Management to define contract terms, including asset allocation, logistics, materials, and skill requirements. Automation and reliable data quality across the procedural chain are essential, supported by IoT sensors, big data analytics, predictive maintenance, intelligent logistics, and asset management.

The Writing is on the Wall: Analyzing the Boom of Inscriptions and its Impact on Rollup Performance and Cost Efficiency

Krzysztof Gogol, Johnnatan Messias, Maria Inês Silva, Benjamin Livshits

Late 2023 witnessed significant user activity on EVM chains, resulting in a surge in transaction activity and putting many rollups into the first live test. While some rollups performed well, some others experienced downtime during this period, affecting transaction finality time and gas fees. To address the lack of empirical research on rollups, we perform the first study during a heightened activity during the late 2023 transaction boom, as attributed to inscriptions - a novel technique that enables NFT and ERC-20 token creation on Bitcoin and other blockchains. We observe that minting inscription-based meme tokens on zkSync Era allows for trading at a fraction of the costs, compared to the Bitcoin or Ethereum networks. We also found that the increased transaction activity, over 99% attributed to the minting of new inscription tokens, positively affected other users of zkSync Era, resulting in lowered gas fees. Unlike L1 blockchains, ZK rollups may experience lower gas fees with increased transaction volume. Lastly, the introduction of blobs - a form of temporary data storage - decreased the gas costs of Ethereum rollups, but also raised a number of questions about the security of inscription-based tokens.

Innovations and smart technologies at Brazilian ports

Darliane Ribeiro Cunha, Sérgio Sampaio Cutrim, Marcelo de Santana Porte, Natália Viana Diniz

Innovations can help ports become smarter and more effective and differentiate themselves from competitors. This study aims to explore the current state of innovations and smart technologies at Brazilian ports. The study sampled sixteen ports, representing 70% of port movements in Brazilian public ports in 2021. This is an exploratory and descriptive field study involving qualitative analysis. The results show that the surveyed ports are seeking strategies to innovate. Only one of the surveyed ports had a registered patent. Half of all ports had agreements with educational/research institutions, companies, or other ports for developing innovations. By contrast, no port engaged in technology transfer contracts with educational/research institutions, companies, or other ports. Few surveyed ports collaborated with HUBs, laboratories, or innovation centres. The three most widely used smart technologies at the surveyed ports were cloud computing, automated systems, and drone technologies. This study shows that Brazilian ports are undergoing a transformation process, but they find themselves in different stages of maturity regarding the appropriation and development of new technologies. New technologies are still incipient for some ports, while others have yet to adopt them. For example, only a few surveyed ports used smart technologies such as the Internet of Things, blockchain technology, or automated systems. Innovations and the inclusion of new technologies can generate benefits, but they require time and financial resources.

Blockchain-Based Secure Traceable Scheme for Food Supply Chain

S. Thangamayan, Kalyani Pradhan, Ganesh Babu Loganathan, S. Sitender · 6 authors

The typical food traceability system’s data layer is made up of relational databases managed by core businesses, which cannot ensure data security. It is inefficient and requires a lot of upkeep. The food supply chain has numerous actors, making it difficult for consumers to safeguard their rights when purchasing food with quality issues. Due to the numerous organizations involved in the food supply chain, food safety monitoring and traceability have become challenging. The supply chain’s major organizations have control and administrative authority over the data under the current food traceability system, which is overly centralized for traceability information. The safety and dependability of food may be ensured by using the food traceability system to track food information. We can witness a series of detailed insights into food from the manufacturing source to the consumption terminal. A blockchain-based food tracking system is created as a solution to these issues. On the Ethereum platform, the system was created. It was also employed in the blockchain system, in addition to its features of decentralization, tamper-proof, and traceability. To implement the data update service and the food recall function, introduce the Food and Drug Administration node. Consumers have the option to not only enquire about food traceability throughout the manufacturing process but also to file complaints regarding the traceability system’s rights protection.

Kadim Lahcen Nadime, Jamal Benhra, Rajaa Benabbou, Salma Mouatassim

The rapid growth of e-commerce has placed considerable strain on traditional logistics systems, prompting a need for innovative solutions to optimize delivery processes and enhance customer satisfaction. This research paper presents a decentralized crowdsourced delivery application that leverages blockchain technology and smart contracts to address the challenges faced by centralized logistics models. The proposed system allows e-commerce companies to outsource product deliveries to carriers from a diverse pool, offering greater flexibility and cost-effectiveness while also enhancing transparency and trust among all parties involved. Built on the Ethereum blockchain, the application manages both the delivery and return processes, generating verifiable proofs of delivery (PoD) and proofs of return (PoR) for each transaction. The paper provides a comprehensive analysis of the system architecture and the implementation of the application using smart contracts. Furthermore, it explores the potential impact of the proposed system on e-commerce companies, carriers, and customers, and identifies challenges and future directions for research and development in this field. The findings of this study contribute to the ongoing discourse on the transformative potential of blockchain technology and crowdsourcing in the e-commerce logistics industry, offering valuable insights into the design and real-world application of a decentralized delivery system.

Intelligent Transportation Logistics Optimal Warehouse Location Method Based on Internet of Things and Blockchain Technology

Jun Chen, Shiyan Xu, Kaikai Liu, Shuqi Yao · 6 authors

In order to cut down on costs to the greatest possible extent, enterprises hope to distribute goods to different customers at the lowest costs possible. Based on this, this paper proposes an optimal location method for an intelligent transportation logistics warehouse. This scheme combines a variety of complex mechanisms to allow IoT devices to provide input. The scheme makes full use of the irreducibility of a blockchain system to promote the development and design of blockchain logistics applications. This method is aimed at tracking the progress of transportation of products in the whole supply chain. Experimental results show that, compared with traditional methods, the optimal positioning method has the advantages of fewer calculations, a high positioning accuracy, and a low overall cost, and it obtains the best warehouse positioning results. Based on the Internet of Things and blockchain technology, the application of intelligent logistics systems enables enterprises to intuitively understand their current inventory and the transportation status of goods, thus better controlling changes in enterprise resources.

Enacting the Last Mile: Experiences of Smart Contracts in Courier Deliveries

Ella Tallyn, Joe Revans, Evan Morgan, Keith Fisken · 5 authors

Smart contract systems could change the nature of last-mile delivery for the better through enhanced precision, coordination and accountability. However, technological complexity poses a challenge for end-users participating in the design process, making it hard to explore their experiences and incorporate their perspectives. We describe a case study where technological prototypes create smart contract experiences for professional couriers and receptionists, allowing them to speculate about emerging possibilities, whilst remaining grounded in their current practices. Participants enacted a series of deliveries, choreographed by smart contracts, and their responses were explored in post-experience, one-to-one interviews. Working with professionals to explore the potential impact of smart contract technologies, revealed the systemic webs of value underlying their existing work practices. This has implications for design of such technologies, in which increased automation, efficiency and accountability must be delicately balanced with the benefits of sustaining personal values, relationships and agency.

Blockchain-driven handling of digital freight information: a tensions perspective.

Tim Gruchmann, Oliver Bischoff

Blockchain technology is provoking significant transformations in the logistics industry, creating a complex environment that challenges business change. This study endeavors to advance the research regarding blockchain-based logistics management by identifying tensions and paradoxes accompanying blockchain adoption for handling digital freight information. Addressing the gap of scarce empirical research on adopting this technology, we conducted 12 expert interviews in the German logistics industry. While confirming and advancing previous research, we found several incompatibilities between the technology and its application, as practitioners tend to adopt blockchain features selectively instead of full acceptance of the respective privacy model. Our analysis reveals that the automation of several functionalities on a platform is among the features of blockchains with the greatest potential to create change in handling digital freight information when related governance mechanisms are in place. Building on these findings, the study proposes main strategies to manage the observed tensions, particularly separation, differentiation, and integration strategies. Thereby, our research contributes to the understanding of digital transformations based on immutability and disintermediation when logistics service providers are engaged in blockchain projects.

Blockchain in agricultural supply chain management

Li Bingzhang, Vladimir Zirianov

The problem of minimizing the number of intermediaries in the supply chain is long overdue in the logistics industry. How to carry out logistics operations without the participation of a large number of intermediaries, whose main task is to guarantee the transaction and document flow? Is this possible with Blockchain technology? While this technology is still evolving, there are still many challenges that remain to be addressed. One of the main challenges in implementing this technology in logistics is to reach agreement on its use among all stakeholders. When interaction between different stakeholders in the supply chain with different interests is achieved, then the full potential of this technology to improve the efficiency of logistics processes will be revealed. This will facilitate the emergence of new business models and processes in global trade logistics and increase transparency in the supply chain. Smart contracts with embedded business rules promise not only to reduce transaction costs but to create more agile value chains that enable closer cooperation.

City logistics: Towards a blockchain decision framework for collaborative parcel deliveries in micro-hubs

Marko Hribernik, Kathrin Zero, Sebastian Kummer, David M. Herold

The growth in e-commerce has led to increased pressure within the courier, express and parcel (CEP) sector to tackle the ‘last-mile’ issue and come up with solutions that not only satisfy the customers, but also other stakeholders such as city councils and other regulatory bodies. Scholars have highlighted micro-hubs and the associated horizontal collaboration as a possible solution, which might help alleviate problems associated with last-mile logistics in inner-city centers. However, trust and data exchange issues are considerable barriers to the introduction of horizontal collaboration, in particular between CEP carriers. To address the lack of trust and the issue of data exchange between carriers, the use of blockchain technology may present a solution, but existing research so far is limited concerning frameworks that specifically discuss blockchain technology in the context of micro-hubs and last-mile deliveries. In response, this paper presents a blockchain decision framework for a horizontal collaboration between CEP carriers based on key characteristics of existing blockchain decision models and relevant related research in the area of logistics and last-mile distribution. This is the first study that specifically addresses the use of blockchain technology for horizontal collaboration in the context of micro-hubs and last-mile deliveries.

GeoPact

Ella Tallyn, Joe Revans, Evan Morgan, Dave Murray-Rust

This paper presents GeoPact, an assembly of technological objects that materialises location-aware smart contracts using internet of things and digital ledger technologies. Such contracts may facilitate the creation of distributed systems and services for transport and logistics that are locally constructed and adaptable, thus supporting specific community needs and sustainable objectives. However the technological infrastructures that underpin these systems are complex, making it difficult to engage publics in design processes. GeoPact grounds infrastructure in relatable physical activities, that are linked with holistic views of the system, and creates new experiences for public engagement. In these activities participants were invited to roleplay as couriers, and to progress through delivery scenarios which were governed by smart contracts. Participants and spectators were then encouraged to discuss their reactions, concerns and ideas. This paper illustrates the GeoPact assembly and reflects on our engagement activities.

Improved load planning of roro vessels by adopting blockchain and internet-of-things

Lawrence Henesey, Y. Lizneva, Robert Philipp, Christopher Meyer · 5 authors

Ports are vital to the global economy, as up to 90% of goods are transferred through seaports. With increasing vessel sizes, cargo volumes and higher demand for supply-chain optimization, seaports are required to be more efficient and competitive. In the present study, a proposed solution incorporating IoT and Blockchain is considered into automating many of the activities in the load planning process, which is then evaluated via simulation. Real data is collected concerning different types of cargo for RoPax vessels with the intended goal of reducing planning time in a seaport. The results contribute as one piece of the mosaic on the avenue towards becoming a “Smart Port”, which deploys various digitalization technologies in order to become a fully automated port. The suggested approach to be integrated, builds upon IoT sensors in combination with the lightweight version of a Blockchain to improve balance indicators on a trim of a vessel. A developed simulation tool was used for evaluating a number of scenarios, with each scenario run set to 2500 times. The simulation results indicate an improvement of 50-160% from the current load planning operations for RoPax vessels.
