Abstract
Freight transportation is characterized by highly dynamic information processes:
customers call in orders over time to move freight; the movement of freight over
long distances is subject to random delays; equipment failures require last minute
changes; and decisions are not always executed in the field according to plan.The
high-dimensionality of the decisions involved has made transportation a natural
application for the techniques of mathematical programming,but the challenge of
modeling dynamic information processes has limited their success.In this chapter,
we explore the use of concepts from stochastic programming in the context of resource
allocation problems that arise in freight transportation.Since transportation
problems are often quite large,we focus on the degree to which some techniques
exploit the natural structure of these problems.Experimental work in the context
of these applications is quite limited,so we highlight the techniques that appear to
be the most promising.

摘要
货物运输的特点是高度动态的信息流程:客户来电命令在一段时间内提出货物; 移动货运长途跋涉是受任意拖延; 设备故障需要最后一分钟改变; 并决定并非总是签在外地按计划完成.高维度的决策参与了交通运输的天然应用技术的数学规划 但是,挑战建模动态信息进程,因而限制了他们的成功.在这一章中,我们探索利用的观念,从随机规划方面的资源分配中出现的问题tr运费 湍流.由于交通问题往往是相当大的,我们集中的程度,到一些技巧利用自然结构这些问题.试点工作,在这些申请的时间非常有限,因此,我们强调技术,似乎是最有前途的.
