内容摘要
To overcome imbalance between vehicle supply and demand in different service regions, a micromobility operator can crowdsource individual riders with reward incentives in addition to engaging a third-party logistics provider (3PL) to relocate the vehicles. We construct a time-space network with multiple service regions. In the first stage, the operator decides the initial vehicle allocation for the regions, whereas in the second stage, he determines subsequent vehicle relocation across the regions over an operational horizon. We show that the budgets for acquiring vehicles and for rider crowdsourcing significantly impact the vehicle initial allocation and subsequent relocation. The 3PL is more efficient for mass relocation than rider crowdsourcing, while the latter is more efficient in handling sporadic relocation needs. To serve a region, the 3PL often relocates vehicles in batches from faraway, low-demand regions around peak hours of a day, whereas rider crowdsourcing relocates a few vehicles each time from neighboring regions throughout the day. Furthermore, rider crowdsourcing relocates more vehicles under a unimodal customer arrival pattern than a bimodal pattern, whereas the reverse holds for the 3PL.
