摘要:

考虑路段充电和时间窗的电动车取送货问题,以最小化车辆总旅行距离为目标,结合车辆容量约束、时间窗约束和电量约束等限制,决策一组最优的车辆线路。该问题公式化为一个混合整数线性规划模型,提出一种变邻域搜索算法求解该问题。数值算例用于验证模型的性质和算法的性能。结果表明:在小规模算例中,提出的算法只比商业求解器CPLEX差0.08%;但在大规模算例中,算法能求出高质量的可行解而CPLEX在规定时间内无法得到可行解。

Abstract:

In this paper, the electric vehicles pickup and delivery problem considering link recharging and time windows was studied. Aims to minimize the total travel distance of vehicles, considering the constraints of vehicle capacity, time windows and battery capacity, etc., to determine a group of optimal vehicle routes. The problem is formulated as a mixed integer linear programming model; a variable neighborhood search algorithm is proposed to solve it. Numerical instances are used to verify the model properties and algorithm performance. The results show that the proposed algorithm is only 0.08% worse than the commercial solver CPLEX in small scale instances; however, in large scale instances, the algorithm can obtain high quality feasible solutions in the specified time, in contrast to the CPLEX.

Key words: logistics engineering, pickup and delivery problems, variable neighborhood search algorithm, electric vehicle, recharging link
