Title: Managing the Repositioning Problem in Bike-Sharing Systems
（自転車シェアシステムにおける再配置問題：ロンドンを例に）

概要：The presence of enough bicycles and free docking points to satisfy user demands in stations is a known operational issue in bicycle-sharing schemes. Empty and full stations in such systems are equally undesirable and disruptive for the operation of the network, since the former turn away potential users while the latter could not be used to terminate bicycle journeys. Repositioning practices have been used in the past to address this situation with partial success. This study introduces a new planning approach for such activities, addressing both routing and assignment aspects of bicycle repositioning using a fleet of carrier vehicles. A case study on bicycle usage patterns from a large bicycle-sharing scheme is carried out; examples are also provided that demonstrate the behaviour of the algorithm. Implementation concerns and means to improve computational performance are also discussed.

Note: Towards the end of the seminar (or privately), Dr. Panageotis could also talk about some of his ongoing work on infrastructure resilience.
