1. What contributions have the authors mentioned in the paper "Fleet management for autonomous vehicles using flows in time-expanded networks" ?
The VIPAFLEET project aims at developing a framework to manage a fleet of Individual Public Autonomous Vehicles ( VIPA ).. The authors consider a fleet of cars distributed at specified stations in an industrial area to supply internal transportation, where the cars can be used in different modes of circulation ( tram mode, elevator mode, taxi mode ).. The authors treat in this paper the pickup and delivery problem related to the taxi mode by means of flows in time-expanded networks.

2. What are the future works in "Fleet management for autonomous vehicles using flows in time-expanded networks" ?
Finally the authors provide the time needed to compute the optimal offline solution, the average runtime of REPLAN per recomputation step and the maximum runtime maxR of the recomputation steps of REPLAN.. The authors can conclude that the here proposed REPLAN strategy is already a promising algorithm to handle the Online TMP for the taxi mode in the studied VIPAFLEET management system.. As future work, the authors plan to improve the runtime of REPLAN by reducing the time-expanded network built in each replanning step without loss of optimality.. The authors also plan to study another variant of the TMP without the here required condition that, at each time, at most one request r j can be served by a VIPA and that this has to be done in a direct way along a shortest path from x j to y j.
