A model for the evaluation of environmental impact indicators for a sustainable maritime transportation

Lizzette Pérez LESPIER, Suzanna LONG, Tom SHOBERG, Steven CORNS

《工程管理前沿（英文）》 2019年第6卷第3期页码 368-383 doi: 10.1007/s42524-019-0004-9

摘要： Maritime shipping is considered the most efficient, low-cost means for transporting large quantities of freight over significant distances. However, this process also causes negative environmental and societal impacts. Therefore, environmental sustainability is a pressing issue for maritime shipping management, given the interest in addressing important issues that affect the safety, security, and air and water quality as part of the efficient movement of freight throughout the coasts and waterways and associated port facilities worldwide. In-depth studies of maritime transportation systems (MTS) can be used to identify key environmental impact indicators within the transportation system. This paper develops a tool for decision making in complex environments; this tool will quantify and rank preferred environmental impact indicators within a MTS. Such a model will help decision-makers to achieve the goals of improved environmental sustainability. The model will also provide environmental policy-makers in the shipping industry with an analytical tool that can evaluate tradeoffs within the system and identify possible alternatives to mitigate detrimental effects on the environment.

Enhancing the terrain adaptability of a multirobot cooperative transportation system via novel connectors

《机械工程前沿（英文）》 2023年第18卷第3期 doi: 10.1007/s11465-023-0754-2

摘要： Given limited terrain adaptability, most existing multirobot cooperative transportation systems (MRCTSs) mainly work on flat pavements, restricting their outdoor applications. The connectors’ finite deformation capability and the control strategies’ limitations are primarily responsible for this phenomenon. This study proposes a novel MRCTS based on tracked mobile robots (TMRs) to improve terrain adaptability and expand the application scenarios of MRCTSs. In structure design, we develop a novel 6-degree-of-freedom passive adaptive connector to link multiple TMRs and the transported object (the communal payload). In addition, the connector is set with sensors to measure the position and orientation of the robot with respect to the object for feedback control. In the control strategy, we present a virtual leader–physical follower collaborative paradigm. The leader robot is imaginary to describe the movement of the entire system and manage the follower robots. All the TMRs in the system act as follower robots to transport the object cooperatively. Having divided the whole control structure into the leader robot level and the follower robot level, we convert the motion control of the two kinds of robots to trajectory tracking control problems and propose a novel double closed-loop kinematics control framework. Furthermore, a control law satisfying saturation constraints is derived to ensure transportation stability. An adaptive control algorithm processes the wheelbase uncertainty of the TMR. Finally, we develop a prototype of the TMR-based MRCTS for experiments. In the trajectory tracking experiment, the developed MRCTS with the proposed control scheme can converge to the reference trajectory in the presence of initial tracking errors in a finite time. In the outdoor experiment, the proposed MRCTS consisting of four TMRs can successfully transport a payload weighing 60 kg on an uneven road with the single TMR’s maximum load limited to 15 kg. The experimental results demonstrate the effectiveness of the structural design and control strategies of the TMR-based MRCTS.

Improving the resilience of maritime supply chains: The integration of ports and inland transporters

《工程管理前沿（英文）》页码 51-66 doi: 10.1007/s42524-022-0231-3

摘要： The adverse impact of the outbreak of COVID-19 has reduced ports’ operational efficiency. In addition, ports and inland logistics providers are generally independent of each other and difficult to work together, which leads to time loss. Thus, as the core player, ports can integrate with inland logistics providers to improve the efficiency and resilience of maritime supply chains. This study examines the strategic options of two competing maritime supply chains consisting of ports and inland logistics providers. We investigate the impact of cooperation between ports and inland logistics providers and government regulation on the maritime supply chain by comparing members’ optimal pricing and overall social welfare under centralized, decentralized, and hybrid scenarios. Results indicate that the hybrid scenario is an equilibrium strategy for maritime supply chain, although this strategy is not optimal for governments seeking to improve supply chain resilience and maximize social welfare. Furthermore, observations show that through government economic intervention, both seaborne supplies can be incentivized to adopt an integrated strategy, and business and society can achieve a win–win situation.

The Construction of a Green Transportation System of China

Zhi-huan Fu,Qing-zhong Luo,Guang-zhi Jia

《工程管理前沿（英文）》 2014年第1卷第1期页码 3-12 doi: 10.15302/J-FEM-2014003

摘要： Since the 21st century, the transportation industry in China has achieved rapid growth with a significant increase in the transport capacity; however the development has also greatly impacted the energy saving & environmental conservation. This paper takes into account non-commercial vehicles such as private cars in the statistics of energy consumption and pollution of Chinese transportation system. This method extends on previous methods which solely include commercial vehicles in these statistics. Based on more comprehensive quantitative data, it reviews the progress in the energy saving and environmental conservation efforts by the Chinese transportation industry and points out that the rapid increase of energy consumption and pollution emission and the deterioration of traffic congestion are prominent problems in the development of the Chinese transport industry. The main reasons for theses problems include the unbalanced development of different transport modes, the irrational layout of integrated transport hubs, the inadequate law, regulations and standards, and the use of suboptimal technology. Based on these findings, this paper proposes several goals for the construction of a green transportation system in China including the establishment of a transportation management system, the improvement of transportation energy efficiency, the control of environmental pollution and the alleviating of urban traffic congestion. Additionally, it points out that in order to build a green transportation system in China, multiple aspects should be enhanced, i.e., the formulation of traffic planning, the optimization of transport structure, the development of urban public transport, improvement of integrated hubs, administration of energy saving and environmental conservation, development of intelligent transportation systems, technical innovations, etc..

Development of New Modality Municipal Public Transportation for Guangzhou—Group Rapid Transit System

Ru-jiang Zhao,Wung Hee Moh

《工程管理前沿（英文）》 2015年第2卷第4期页码 378-390 doi: 10.15302/J-FEM-2015061

摘要： As one of the primary business centers of China, Guangzhou has been undergoing rapid growth and expansion. Over the past decade, the Guangzhou Municipality Government has significantly upgraded its transport infrastructure, especially with the highly beneficial expansion of its Subway Mass Rapid Transit (MRT) system. Positive steps have also been taken to continue planning the construction of new roads, a Bus Rapid Transit (BRT) system and other transportation facilities. Further administrative and regulatory measures have also been implemented to control the situation, such as the banning of motorcycles from the central city area and the limitation of new automobile registrations. However, Guangzhou continues to face serious challenges of traffic congestion in and around the city center owing to further intensification of its population with economic growth. The need to ease Guangzhou’s stretched public transportation resources, and at the same time to support the realization of its “Eastward Advance” strategy, presents a unique challenge and opportunity to develop an advanced high-efficiency public transportation modality for Guangzhou, viz. the Group Rapid Transit (GRT) involving the use of automation-guided (driverless) smart-vehicles. This paper outlines the PRT/GRT (PRT: Personal Rapid Transit) smart-vehicle modality and also puts forth a proposal of Guangzhou’s first GRT route as the city’s first dedicated transportation link to the scenic landscape of the Eastern Tourism Zone. This GRT route will help in diffusing the city’s traffic congestion as well as support the effectuation of Guangzhou’s “Eastern Expansion” strategy, supplementing the ongoing expansion of the Guangzhou Municipality’s subway MRT networks.

Sustainable urban transportation development in China: A behavioral perspective

《工程管理前沿（英文）》 2022年第9卷第1期页码 16-30 doi: 10.1007/s42524-021-0162-4

摘要： The rapid development of economics requires highly efficient and environment-friendly urban transportation systems. Such requirement presents challenges in sustainable urban transportation. The analysis and understanding of transportation-related behaviors provide one approach to dealing with complicated transportation activities. In this study, the management of traffic systems is divided into four levels with a structural and systematic perspective. Then, several special cases from the perspective of behavior, including purchasing behaviors toward new energy vehicles, choice behaviors toward green travel, and behavioral reactions toward transportation demand management policies, are investigated. Several management suggestions are proposed for transportation authorities to improve sustainable traffic management.
