Open loading-unloading mode of refined oil shipment will cause oil gas to escape, which not only refers to the environmental pollution but also economic losses. Therefore, closed mode with oil-gas recovery has attracted more attention. In this paper, oil-gas recovery is taken into account from an environmental perspective, incorporated into green vehicle routing problem (GVRP) in refined oil distribution. The main problem involves: I) depict the relationship between costs and benefits of oil-gas recovery, calculate the optimal rate of oil-gas recovery; II) compare the effect on loading-unloading speed in different modes, and confirm the adjusted impact on delivery time. Then, a multi-objective model for GVRP is built, and a NSGA-III algorithm with three layers coding is designed to solve the proposed problem. Finally, the numerical results show that NSGA-III algorithm performs better than others; oil-gas recovery efficiency will be higher with high environmental temperature. In addition, oil-gas recovery can also save delivery time, and the effect of joint optimization in refined oil distribution with oil-gas recovery is better than that of independent optimization.
