摘要
针对集配货一体化车辆路径问题的特性,建立了考虑配送车辆出行固定成本、车辆出发满载系数等因素的更加符合实际的数学模型;并设计了一种带记忆功能的模拟退火算法求解模型,确保输出结果是每次寻优的最优解;最后通过算例计算,结果表明,算法求解更优,稳定性更好,计算效率也较高。
According to the characteristic of vehicle muting problem with pick - up and delivery, this paper establishes a more practical mathematical model, including vehicle fixed cost and vehicle full -load coefficient. To solve the model, the paper designs a new simulated annealing algorithm with memory function to obtain the optimal solution. At last, we test the new algorithm through a 20 -customer example. The experimental results show that the new algorithm can obtain better solution with better stability and high calculation efficiency.
