How to plan transports?5 answersTo plan transports effectively, it is essential to consider various aspects such as performance evaluation criteria, economic viability, safety, environmental impact, and spatial optimization. Planning involves setting targets for transport development, ensuring financial feasibility, enhancing transport safety, reducing emissions, and utilizing space efficiently. Utilizing advanced technologies like GIS can aid in optimizing transport routes, improving decision-making, and reducing subjective errors. Additionally, employing innovative equipment like planning and transporting machines can enhance mechanized coal mining processes, ensuring safe operations and increased efficiency. Implementing scraping conveyors with dual control cylinders can optimize material cutting and conveying, especially in inclined and thin coal seams, leading to lower power consumption and higher productivity. By integrating these strategies and technologies, a comprehensive and efficient transport planning approach can be achieved.
How to modeling ship route planning?5 answersShip route planning can be modeled using various methods. One approach is to establish a dynamic sea area model with meteorological and oceanographic data sets to delineate navigable and prohibited areas. Another method involves creating a mathematical model that considers the impact of nonuniformity in the offshore wind field on ship route planning, with the goal of minimizing sailing time. Additionally, ship multi-constraint route planning can be achieved by clustering AIS feature trajectories and improving the ant colony algorithm. Another approach combines the Automatic Identification System (AIS) data with the ant colony algorithm and A* search algorithm to obtain the shortest route that meets navigation requirements. Lastly, the dynamic window approach combined with field theory can be used to model the environment and search for the optimal shipping route.
What are the most commonly used road transport models for evaluating traffic flow and congestion?4 answersThe most commonly used road transport models for evaluating traffic flow and congestion include macro-simulation and micro-modeling. Macro-simulation allows for analyzing overall traffic flow without detailing individual vehicle movement, making it useful for evaluating different scenarios and road traffic management strategies. Micro-modeling, on the other hand, involves creating detailed mathematical models to analyze vehicle movement in specific areas such as intersections and street sections. It helps in evaluating changes to the transportation network and avoiding inefficient use of funds. Additionally, artificial intelligence (AI) and machine learning (ML) techniques, such as recurrent neural networks (RNNs) and deep learning models, have been used to predict traffic congestion levels and estimate the effectiveness of road-specific congestion. These models can be trained on real-time traffic data and offer more accurate estimations of congestion levels in a road network.
What business analytics oublic transportation needs?5 answersBusiness analytics is leveraged in the transportation industry to create business value by optimizing capital expenditure, reducing operating costs, improving profitability, improving reliability, reducing risks, and achieving compliance. It helps transportation providers be more efficient in their operations while controlling costs as they scale. Analytics is used to solve specific business problems in the transportation industry, such as global market expansion strategy for a private air medical company, evaluating the performance of express delivery companies in China, analyzing and processing transportation and infrastructure data for better decision-making, identifying transportation needs and evaluating transportation services offered, and digitalizing transportation systems to adapt to Industry 4.0. By using business analytical tools and methodologies, organizations in the transportation industry can address practical demands, make informed decisions, and gain a competitive advantage.
What are the different business models that transportation businesses can use?5 answersTransportation businesses can use different business models to adapt to the changing conditions of the digital economy and improve their services. The specific business models for logistics and transportation companies have been analyzed, and factors influencing the development of these services have been identified. In the context of transportation supply systems, mathematical models are used to simulate the performances and flows resulting from users' demand and the technical and organizational aspects of the physical transportation supply. Additionally, technology-based demand-driven business models, such as Uber and BiTaksi, have been studied and strategies have been proposed based on their practices. Furthermore, the use of data and forecasting models, such as k-means algorithm and regression techniques, can help transportation companies accurately determine ticket prices and improve service quality.
Can I model proppant transport using CMG software?5 answersYes, proppant transport can be modeled using CMG software. Computational modeling has been increasingly used to study proppant transport, and CMG software is one of the commonly used tools for this purpose. CMG software allows for the development of innovative and reliable computational models for proppant transport, providing a comprehensive understanding of the physics and numerical approaches involved. Additionally, CMG software can be used to design and optimize the amount of proppant and additives, injection timing, pressure, and well parameters required for successful hydraulic fracturing. The software incorporates features such as proppant retardation, gravitational settling, and fluid leak-off, which are crucial in accurately predicting the final location and concentration of proppants, and thus the stimulated region. Furthermore, CMG software can be integrated with other simulation tools, such as geomechanics simulators, to model the opening and closure of fractures and the resulting permeability.
