  • 摘要: 考虑驾驶速度偏差, 建立了多驾驶人、多种车型、多种物资、多仓库点和多需求点的物资车辆调度模型, 分别以整体运输时间最短、整体运输成本最低以及综合整体运输时间与成本最小为目标, 研究了个体驾驶速度偏差对上述目标的影响; 将驾驶人参数加入到遗传算法的基因编码中, 建立了驾驶人唯一性约束、初始地点约束以及物资供需数量约束, 保证每个基因个体中驾驶人分配方案可行, 且物资运输不超供需总量; 采用遗传算法求解了随机分配驾驶人条件下有驾驶速度偏差与无驾驶速度偏差时各目标的车辆调度方案。计算结果表明: 优化调度方案满足模型中的所有约束条件; 3种目标下的最优方案中, 驾驶人的分配方案不同, 说明目标函数受驾驶人驾驶速度偏差影响; 有驾驶速度偏差情况下的各目标调度结果均优于相应无驾驶速度偏差的调度结果, 3种目标函数差比分别为3.50%、2.96%和1.13%, 说明驾驶速度偏差对求解质量有一定影响; 驾驶人随机分配时的各目标调度结果均劣于相应最优结果, 3种目标函数差比分别为3.91%、2.47%和1.98%, 说明驾驶速度偏差会影响调度效率, 优化驾驶人分配方案能降低整体运输时间与成本。由此可见, 根据特定的调度目标对驾驶人进行合理分配, 可以得到更符合调度目标、更贴近实际、更经济省时的车辆调度方案。
