Vehicle relocation and staff rebalancing optimizations of one-way car-sharing systems with time flexibility
The imbalance of vehicles is inherent in one-way car-sharing systems.The work proposed a mixed integer linear pro-gramming(MILP)addressing customers'time flexibility to determine the optimal vehicle fleet size,staff number,and request-vehicle-staff matching.The goal was to minimize the cost.A customized decomposition algorithm was developed.Some computa-tional experiments were conducted to illustrate time flexibility.It reduced the total cost by 15.5%and increased the request ac-ceptance rate by 7%.
