最近几年使运输功能引人注目的一个因素就是越来越多地使用及时供应的库存系统。这种系统是以公司储存很少数量的生产投入的生产方式为基础的。它的使用加大了对供货商的运输系统的压力，因为供货商必须有能力在客户需要之时及时运来货物。

They are based on a production approach in which the firm maintains very small quantities of production inputs. The utilization of this system has placed great pressure on the supplier's transportation system because the supplier must be able to deliver products exactly when the customer requires them.
