What papers have studied how to rationally use other hubs when a single hub suffers from heavy passenger flow?
Best insight from top research papers
To rationally use other hubs when a single hub suffers from heavy passenger flow, several papers have addressed this issue. Pan et al. proposed a mixed integer programming model to optimize a coordinated passenger inflow control strategy with collaborative train timetable for a rail corridor, considering both passenger waiting time and operational cost . Hu et al. developed a stochastic programming model for capacitated single allocation hub location problems with uncertain demands, considering the balanced utilization of hub capacities . Rostami et al. tackled the challenge of hub-hub connection costs as piecewise linear functions by building a mixed-integer quadratically constrained program and developing a methodology based on constructing Lagrangian function and linear dual functions . Momayezi et al. proposed a capacitated modular single allocation hub location problem with possibilities of hub disruptions, using a two-stage stochastic program and an adaptive large neighborhood search algorithm . Hu addressed the classical single and multiple allocation hub location problems with fully interconnected hubs, considering balanced round-trip flows on hub links to decrease empty-trip rate and increase full-load rate of vehicles .

Mobility Hubs: A Way Out of Car Dependency Through a New Multifunctional Housing Development?5 answersMobility hubs have emerged as a potential solution to reduce car dependency and promote sustainable transport options in urban areas. These hubs aim to provide convenient access to shared mobility services, such as carsharing, within residential neighborhoods. By integrating various modes of transportation and amenities, mobility hubs can encourage the use of alternative modes of transport and reduce the need for private car ownership. Studies have shown that decentralized mobility hubs can lead to a more positive perception of carsharing and a greater willingness to forgo car ownership. Additionally, the location and materiality of car-reduced housing developments can support car independence and low-carbon mobility. Overall, mobility hubs offer a multifunctional approach to housing development that can help transition towards a more sustainable and less car-dependent urban environment.
What is the importance of student hub?5 answersStudent hubs are important in supporting the wellbeing and learning of students in various fields of study. They provide a supportive community and connections for students, promoting their emotional wellbeing and personal transformational learning. Additionally, student hubs can restrict the usage of cell phones and provide information about college updates, helping students stay focused and informed. In the context of course enrollment, student hubs can be used to form networks of courses based on student co-enrollments, which can help predict upcoming demands for future courses and provide students with realistic course options based on their backgrounds. In the field of environmental safety, educational hubs play a crucial role in the formation and development of professional and practical competence among students. They provide different learning styles and sessions, enabling students to create more complex educational and scientific products through exchange and cooperation. In nursing education, the hub and spoke model enhances practice learning by offering students the opportunity to undertake different placement experiences, make connections, and understand the influence of the community on patients' health and well-being.
What are the latest developments regarding energy hubs?4 answersThe latest developments regarding energy hubs include the investigation of both decentralized and centralized model predictive control (MPC) approaches for a network of energy hubs. While the centralized control strategy offers superior performance, its implementation is computationally prohibitive and raises privacy concerns as extensive information sharing is required. A distributed scheme based on a consensus alternating direction method of multipliers (ADMM) algorithm is proposed to combine the performance of the centralized approach with the privacy preservation of the decentralized approach. Additionally, a multi-objective scheduling model based on a Genetic Algorithm is developed to minimize operational costs and CO2 emissions in an Energy Hub. Furthermore, a stochastic MPC controller is proposed to minimize energy costs using chance constraints for uncertain demands, and a demand prediction model based on Gaussian processes is used to generate future demand forecasts.
What is the state of the art of energy hubs?4 answersEnergy hubs are a promising concept for optimizing multi-carrier energy systems and achieving decarbonization goals. They enable the design, management, and control of integrated networks where multiple energy carriers operate together. The state of the art approaches for energy hub design and operation optimization have been reviewed in the literature. These approaches consider different optimization methods, objective functions, constraints, and market participation mechanisms. The literature also highlights the need for further research and enhancement of existing approaches. The benefits of energy hubs include optimizing energy consumption, reducing greenhouse gas emissions, and integrating renewable energy sources. Levelized cost of energy, CO2 emissions, and cost of hydrogen are important parameters for comparing different energy hubs. Energy storing and transmutation technologies play a vital role in energy-established systems.

What are the primary facets of an engineering study hub?5 answersAn engineering study hub is characterized by several primary facets. Firstly, it involves the use of Information and Communication Technologies (ICT) to enable better collaboration between customers and suppliers in virtual organizations. Engineering service providers can act as hubs to offer e-services for industrial network collaboration in virtual product development teams. Secondly, trust building is a vital aspect of an engineering hub, and it can be fostered through collaborative project planning and transparent contract negotiation platforms. Additionally, engineering hubs provide e-services and utilize web services as a technological solution to support collaboration among engineers. Lastly, the success of an engineering hub relies on the development of a secured and reliable online contracting system, which requires addressing legal and contractual issues specific to e-hubs.
