Distributed Event-Triggered Dual Decomposition Method for Cooperative One-Way Car-Sharing Control

In this paper, we present cooperative rebalancing control of a one-way car-sharing service, where several service providers operate vehicles independently while sharing the common rental stations. The objective of service providers is to reduce the number of deadhead vehicles considering limited parking slots at stations. To this end, we propose a rebalancing control method by a distributed dual decomposition algorithm. Each provider transmits the estimation of the dual optimizers to the neighboring providers in an event-triggered manner. A numerical example shows that all service providers can find an optimal rebalancing solution while effectively reducing the number of communications.
