About the Lecturer：
Professor Xie Chi acquired his Doctor’s Degree in Systems Engineering from Cornell University in 2008. He has successively taught in the University of Texas, Shanghai Jiaotong University and Tongji University. He is currently a professor and Ph.D supervisor in the School of Transportation Engineering and Urban Transportation Research Institute of Tongji University. His main research fields include "Traffic Network Management and Control", "Urban Transportation And Energy System Planning", "Urban Shared Transportation And Logistics System", "Freight And Logistics System Optimization", etc. He masters in the way of combining multiple subjects, such as Operation Research and Management Science, Micro and Regional Economics, Cognition and Behavior Science, etc., to analyze and predict the economic and social phenomena in transportation system. Also, he establishes optimization model and provides strategic decision for the planning, control, operation and management of large-scale integrated transportation system. His research findings have been published in more than 100 academic papers, book chapters and research reports, including more than 50 international journal papers. He was selected into the "Youth Thousand Talents Program" of the Organization Department of the Central Committee in 2013, and was selected as a guest speaker of China-America Frontiers of Engineering Symposium jointly sponsored by Chinese Academy of Engineering and American Academy of Engineering in 2017. He won the excellent paper award of World Transportation Conference in 2018 as well as the UNSW visiting Professional Fellowship and RISUD Visiting Fellowship in 2014 and 2020 respectively.
Professor Xie Chi is currently the Deputy Editor in Chief of International Journal of Transportation Science and Technology, the chairman of Transportation and Logistics System Planning and Co-Chairman of Waterway Transportation System Optimization, member of Freight Planning and Logistics Committee of Transportation Research Council of USA, and expert member of Advisory Committee of South China Transportation and Logistics Development Research Center.
About the Lecture:
Though its first use dates back to 1940s, carsharing has not widely attracted the public’s awareness, until the last decade as an emerging form of shared economy. Different from the eodem loco pickup-and-dropoff policy enacted by traditional car rental companies, most of current carsharing services allow for taking and returning a shared car at different service stations. This one-way setting greatly enhances travelers’ car renting and returning convenience and hence increases the attractiveness and competitiveness of carsharing in the transportation service market. Such flexibility, however, comes up with a serious imbalance problem between car supply and user demand across stations. To reduce the negative impacts due to the supply-demand imbalance, carsharing planners and managers suggested various technological and managerial rebalancing strategies. The most primitive and widely used strategy is vehicle relocation, the main operation of which is to employ full-time or part-time human operators or stimulate vehicle users by economic incentives to drive cars from stations with car abundance to other stations with car shortage. Obviously, in a large-scale carsharing system, these operator dispatchment and user stimulation operations are rather time- and cost-consuming, calling for a complex decision process executed at a frequent basis in real time and involving hundreds or even thousands of vehicles. This presentation records some of research advances made by Prof. Chi Xie’s research group on how to optimize vehicle relocation operations for one-way carsharing systems by using multiple resources (such as professional operators, designated drivers and vehicle users) simultaneously.
