综合考虑逆向物流中的车辆路径问题和选址分配问题,首先分析问题的特点,并建立问题的数据模型,然后提出一种基于贪心算法的改进粒子群优化算法.实验结果表明,新算法能够以较快的收敛速度得到问题的近似最优解,是解决该类问题的有效方法.
Vehicle routing problem (VRP) and location allocation problem (LAP) of reverse logistics (RL) are synthetically considered. The features of the problem are analyzed. A mathematical model of the problem is constructed. An improved particle swarm optimization (PSO) algorithm based greedy algorithm is proposed. The experiments show that the new algorithm can approach the optimal solutions quickly which proved it to be an efficient method in solving such problem.
