Thermal modeling and analysis of multi-mover motors considering mover quantity and dynamic states

—Multi-mover motors are widely used in logistics transportation systems. However, the unique number of movers and variations in motion states complicate the distribution of loss and thermal characteristics, thereby increasing the difficulty of calculating temperature rise. In this paper, a winding loss calculation method that considers the multi-condition and dynamic characteristics of multi-mover motors is proposed. The convective heat transfer coefficient (CHTC) is calculated using computational fluid dynamics (CFD) and response surface methodology (RSM), with a detailed analysis of velocity distribution characteristics. The interactive effects of mover speed, acceleration, mover quantity, and the distance between adjacent movers on the CHTC are investigated. A simplified yet accurate thermal modeling is developed, reducing the required time for a single operating condition from 4 h to 0.5 h, with an error of only 4 %. Through both single variable and multivariable analyses, the thermal characteristics of multi-mover motors under different conditions are revealed. Finally, a prototype is created and tested under various operating conditions. The discrepancies between the experimental and calculated values are within 5 %, validating the accuracy of the proposed model and analysis.

Operational Planning and Design Considerations for Underground Logistics Transportation in Texas

The logistics transportation system is critical to the United States economy. Underground Logistics Transportation (ULT) is a class of automated transportation systems in which vehicles carry freight through pipelines and tunnels between terminals. Being able to use a part of the underground space of existing highways will greatly facilitate the construction of such pipelines and tunnels and reduce their construction costs. Underground Logistics Transportation (ULT) could be the answer to make freight transport more sustainable and competitive. Texas highways and railroads are expected to increase by nearly 207% from 2003 to 2030. Truck tonnage will grow by 251%, while rail tonnage is forecasted to increase 118%. The number of trucks carrying NAFTA goods will increase by 263%, and the number of rail units will grow by 195%. This will have a profound impact on the highway and rail systems. The objective of this paper is to present requirements and operational components for three types of ULT lines: standard shipping containers, a standard crate size, and a standard pallet size. This study examines the use of ULT as a mode of underground transportation with the help of three case studies. This research shows that ULT is financially viable, feasible, greener, cost effective, and can become an important part of intermodal freight mobility.

CALCULATION OF THE LOGISTICS SYSTEM CENTER OF THE MAGNUM SUPERMARKET CHAIN IN PETROPAVLOVSK

The logistics system of Magnum supermarkets is the largest in Petropavlovsk, therefore the parameters of transport processes in this system have different directions and values, both in time and in space. Improving the efficiency of the transport logistics system is a priority. One of the factors influencing the efficiency of the transport logistics system is the location of warehouses and stores. In this article, the author calculated the center of the logistics system in order to determine the coordinates of the warehouse location in order to reduce transportation costs. For the calculation, the method of determining the center of gravity of the physical model of the distribution system was used. The results of the work are defined in the form of coordinate values. The calculation method can be used in distribution logistics. The data obtained cannot always be applied in practice, so this calculation method must be used together with other methods for determining the location of the warehouse, for example, the test point method.

In the study, the authors considered peculiarities and prerequisites for development of inland water transport in Ukraine, its role and organizational& economic mechanism for development of inland water transport in the modern military transport system of Ukraine. Inland water transport under influence of active hostilities on the territory of Ukraine should be integrated with other types of transport system: railway, road, to create a cyclical transport logistics system. This mechanism can increase an efficiency and reliability of transport services and reduce costs for related business activities. As the inland water transport plays an important role in the transport system, Ukraine seeks to expand its export markets, its importance will continue to grow under conditions of active hostilities. Therefore, understanding the shortcomings and development trends of the national system of inland water transport will contribute to the process of inland water transport renewal in Ukraine. The goal of the study is to analyse prerequisites for development of inland water transport of mechanisms that take into account the specifics of inland water transport based on their comprehensive analysis in order to conceptualize specific organizational&economic mechanism for its functioning during military influence in Ukraine. In Ukraine, the correspondent risks should be considered in managemental, commercial and industrial aspects of inland water transport in a complex manner. The study analyses the current state of inland water transport and its contribution in ensuring transportation of foreign trade goods within the territory of Ukraine. The specifics of production processes of inland water transport are characterized, and in particular, the influence of weather and climate conditions on them, a significant number of stakeholders involved in the transportation process and the need to obtain a large number of approvals in a realm of inland water transport services and cargo in the port. All this together determines the practical impossibility of clearly defining the time parameters of transport processes in shipping. As a result of the analysis of the commercial aspects of the operation of inland water transport.

MULTIMODAL LOGISTICS IN THE CONDITIONS OF A TURBULENT BUSINESS ENVIRONMENT TRANSPORT & LOGISTICS SYSTEM

The transport industry of Ukraine is an important component of the complex of infrastructural industries and a necessary material factor for ensuring production and logistics. The importance and relevance of the development of transport logistics is also due to its special importance in ensuring the security of Ukraine, especially in conditions of military influence. That is, transport multimodal logistics indirectly affects all components of national security - foreign economic, domestic political, economic, food, environmental, anti-terrorist, informational, scientific and technical, and others. The economic role of transport consists, first of all, in the fact that it is an organic link of every production, carries out continuous and mass delivery of all types of raw materials, fuel and products from points of production to points of consumption, and also ensures the division of labor, specialization and cooperation of production. The purpose of the research is the analysis of the development of the multimodal transport logistics system of the surrounding business environment under the influence of the turbulence of the martial law and in the post-war period. One of the key advantages of multimodal logistics is the ability to use different types of transport depending on the specific stages of the route and infrastructure capabilities. This avoids delays and reduces the risk of loss of time and money. In addition, multimodal logistics allows the use of cargo tracking technologies, which facilitates control over their movement and ensures accurate delivery times. This is important for a business that seeks to provide quality service to its customers. Despite the fact that logistics services are usually complex and expensive, some Ukrainian companies offer them absolutely free of charge. Now Ukraine needs to overcome difficulties and look for new ways. Ensuring security has become the main priority for Ukrainian commodity exports. Summing up, multimodal transport logistics is a strategic approach to optimizing transport flows, which allows to ensure the efficiency and competitiveness of logistics processes in the modern world. Thus, logistics is actively studying the situation and cooperating with government authorities to find bypass logistics routes around dangerous zones and war-torn trade bridges.

Maze Solving Mobile Robot Based on Image Processing and Graph Theory

Advances in the development of collision-free path planning algorithms are the main need not only to solve mazes with robotic systems, but also for their use in modern product transportation or green logistics systems and planning merchandise deliveries inside or outside a factory. This challenge increases as the complexity of the task in its structure also increases. This paper deals with the development of a novel methodology for solving mazes with a mobile robot, using image processing techniques and graph theory. The novelty is that the mobile robot can find the shortest path from a start-point to the end-point into irregular mazes with abundant irregular obstacles, a situation that is not far from reality. Maze information is acquired from an image and depending on the size of the mobile robot, a grid of nodes with the same dimensions of the maze is built. Another contribution of this paper is that the size of the maze can be scaled from 1 m × 1 m to 66 m × 66 m, maintaining the essence of the proposed collision-free path planning methodology. Afterwards, graph theory is used to find the shortest path within the grid of reduced nodes due to the elimination of those nodes absorbed by the irregular obstacles. To avoid the mobile robot to travel through those nodes very close to obstacles and borders, resulting in a collision, each image of the obstacle and border is dilated taking into account the size of the mobile robot. The methodology was validated with two case studies with a mobile robot in different mazes. We emphasize that the maze solution is found in a single computational step, from the maze image as input until the generation of the Path vector. Experimental results show the usefulness of the proposed methodology, which can be used in applications such as intelligent traffic control, military, agriculture and so on.

Key Planning Recommendations For Logistics Multimodal Transport Institutions: Lessons Learned From Tanjung Priok Port In Indonesia

Logistics activities urgently require integration from both infrastructure and management aspects, while logistics activities are currently partial and the development is spread across various Ministries. Therefore, strong governance is needed to support the effective implementation of coordination and to harmonize and integrate all national logistics system development policies. The purpose of this study is to identify the actors participating in the management of the multimodal logistics transportation system, examine the challenges associated with multimodal transportation institution coordination, and determine the function of each actor in multimodal transportation. The success of multimodal transportation in Tanjung Priok’s port as the biggest port in Indonesia has been proven to be hampered due to elements of conflict of interest and adverse selection of informal institutions, according to the findings of the analysis related to the role of actors and problems related to multimodal transportation institutions at ports in Indonesia. Therefore, it is necessary to develop strategies from short to long terms, such as creating a special coordination forum or institution that is ad-hoc in nature for 2-3 years until the core problems of multimodal logistics are completed with the form of the institutional structure being structural and functional, developing a code of ethics to ensure consistent implementation of the long-term agenda, including commitments from institutional coordination of multimodal transport, and to establish permanent institutions as coordination platforms and 'network' organizations to facilitate the strategy of the 'long-term relational contract' concept where the network's focus on practical coordination should be widened and deepened to include more policy coordination until the core problems of multimodal logistics are resolved through institutional forms in the form of Constitution

Leapfrog logistics: digital trucking platforms, infrastructure, and labor in Brazil and China

Critical political economy analyses have principally conceptualised platforms as unproductive economic forms (rentier capital) skimming value off each intermediated transaction and/or illegitimately extracting and capitalizing user data. This scholarship has also focused heavily on extractive dimensions of global North platforms’ operations within the global South. However, a small but growing literature is examining the productive aspects of digital platforms, while important digital platforms are emerging in Southern economies. These trends draw attention to the prospect of platforms playing a role in leapfrog development. This article examines digital trucking platforms in two major economies of the global South: Brazil and China. We argue that trucking platforms are engendering dramatic transformations of these countries’ disorganised road transport logistics systems. Platforms are centralising investment and co-ordinating control. Utilising technologies which surpass those deployed in the global North, they rationalise disorganised and inefficient transport systems by subjecting them to algorithmic rule and minimising bureaucratic inefficiencies. Through greater centralisation, co-ordination and rationalisation, trucking platforms further serve to proletarianize their owner-operator workforces, driving down costs and eliminating barriers to the geographical circulation of capital. While this offers some benefits to workers, it also exposes them to the vagaries of market discipline in new ways.

VeLP: Vehicle Loading Plan Learning from Human Behavior in Nationwide Logistics System

For a nationwide logistics transportation system, it is critical to make the vehicle loading plans (i.e., given many packages, deciding vehicle types and numbers) at each sorting and distribution center. This task is currently completed by dispatchers at each center in many logistics companies and consumes a lot of workloads for dispatchers. Existing works formulate such an issue as a cargo loading problem and solve it by combinatorial optimization methods. However, it cannot work in some real-world nationwide applications due to the lack of accurate cargo volume information and effective model design under complicated impact factors as well as temporal correlation. In this paper, we explore a new opportunity to utilize large-scale route and human behavior data (i.e., dispatchers' decision process on planning vehicles) to generate vehicle loading plans (i.e., plans). Specifically, we collect a five-month nationwide operational dataset from JD Logistics in China and comprehensively analyze human behaviors. Based on the data-driven analytics insights, we design a <u>Ve</u>hicle <u>L</u>oading <u>P</u>lan learning model, named VeLP, which consists of a pattern mining module and a deep temporal cross neural network, to learn the human behaviors on regular and irregular routes, respectively. Extensive experiments demonstrate the superiority of VeLP, which achieves performance improvement by 35.8% and 50% for trunk and branch routes compared with baselines, respectively. Besides, we deployed VeLP in JDL and applied it in about 400 routes, reducing the time by approximately 20% in creating plans. It saves significant human workload and improves operational efficiency for the logistics company.

The improvement of port processes relies very much on the development of Information and Communication Technology (ICT) and Industrial Control Systems (ICS) or Operation Technologies (OT) systems. In port environment there are parts that are controlled (ICS/OT) from the cyber environment but directly interact with the physical surroundings. These are called Cyber-Physical Systems (CPS). In this environment, the cyber security aspects of the port logistic need to be addressed. In Finland, the Port SMARTER research program has been on the way since 2021. The aim of the program is to create port services within new technology solutions, and that way improve cargo and people flows while improving the experience for all stakeholders. However, this development increase also complicated system dimensions in the use of ports and makes port operations complex systems of systems environment characterized by a conglomeration of interconnected networks and dependencies. This paper describes a practical approach to risk assessment work regarding the SMARTER research case. It provides a comprehensive cyber security investigation approach to port operations at the system level. In risk assessment work, the paper emphasizes the importation of description of probabilities to defend the system element against estimated probabilities of cyber-attacks at all parts of port processes. The findings of the study are related to the comprehensive cyber security architecture of the SMARTER research goals. The following research interests are related to the issue: "How a comprehensive cyber security investigation can be conducted in smart ports operations?” This paper emphasizes cyber security risks assessment work should be covered from services for operation, information flows in and between systems, as well as electricity supplies to achieve holistic risks assessment in the smart terminal process.

МОДЕЛІ НАДАННЯ ТРАНСПОРТНИХ ПОСЛУГ СИЛАМИ ЛОГІСТИКИ

Approaches to modeling logistical support projects of motor vehicle units of military formations, taking into account the specifics of activity, including combat, in relation to the Armed Forces of Ukraine and other components of the Defense Forces on the basis of logistic approaches are proposed. The positive result of logistics support largely depends on the rational use of resources, cost reduction, etc. The most acceptable approach to modeling military transportation tasks is a knowledge-oriented approach and its combination with deterministic-optimal and probabilistic approaches. Unlike existing models, models based on a knowledge-oriented approach provide the opportunity to: use quality indicators; taking into account inaccurate information about the meaning of signs; using the knowledge of specialists in auto technical support - experts, which are presented in the form of vague rules of conclusion; obtaining a more qualitative assessment of the object being investigated during the organization of auto technical support of military units. As experience shows, this is achieved by implementing logistics information systems. Their implementation requires the development of an appropriate model. Models of transport logistics are presented in terms of development forecast, work planning and operation. Three groups of models are distinguished: deterministic-optimal, probabilistic and knowledge-oriented. The application of knowledge-oriented models provides an opportunity to: use both quantitative and qualitative indicators; taking into account inaccurate, approximate information; using the knowledge of specialists, which are presented in the form of vague rules. The proposed approach requires the development of methodological support for the construction of transport logistics systems and is a perspective for further research in this direction.
