7、离运输，送到当地分拨点。因为当地分拨点可以从仓库提货，而不必直接向印刷厂订货，因而不会常常变化生产计划，所以生产成本也可能会因此降低。,10-14,该总裁随后做出如下粗略的成本估算（针对需要印刷500万册资料的典型活动） 从工厂直接运输 通过35个仓库运输 成本变化 运输成本： 至仓库 0 50000 50000 至当地 250000 100000 150000 仓储成本 0 75000 75000 总计 250000 225000 25000 运输费用的降低在抵消增加的仓储费用后还有节余。看起来，利于仓库节约成本，是一种非常有吸引力的方法。,案例,10-15,Warehousing Mana
