Vehicle-scheduling Problems with Uncertainty and Omitted Customers
研究了车辆调度中客户需求不确定的情况，特别是部分客户在调度期内不需要配送时，比较了半固定路线与重新调度的成本节约，对批发分销商有参考价值。
The standard vehicle-scheduling problem is deterministic, assuming all factors are known with certainty in advance of scheduling. In practice there are several areas which might contain uncertainty. This paper suggests ways of tackling these, but concentrates on problems where some customers do not need deliveries during a scheduling period. If the number of such customers is small, semi-fixed routes may be acceptable. As the number of customers omitted rises, there comes a point when rescheduling becomes preferable. The potential savings made by semi-fixed or variable routes over fixed routes are estimated for standard problems. The implications of these savings are then evaluated for a wholesale distributor.
