摘    要:探讨一类占线订单加工问题,具体分析当订单交货时间具有一定上限约束时的不可中断和可中断两种模型。对于不可中断模型,证明先到先服务策略在两种不同交货期限约束时分别是最优策略与最优占线策略;对于可中断模型,提出了基于先到先服务原则的可中断策略,并证明当交货期限小于3倍加工时间时该策略具有竞争比3/2。

关 键 词:订单加工  占线策略  竞争比  确定性策略

Abstract:This paper investigates the on-line order scheduling problem considering due date.For non-preemptive model,(we prove) that when each order has a due date at most two times of its processing time,the FCFS strategy is optimal.(Otherwise) FCFS has a competitive ratio equal 2,which meets the lower bound for deterministic strategies in that case.For preemptive-restart model,we present a deterministic strategy called PFCFS,and also prove that it has a competitive ratio(equal) 3/2 when the due date of each order is strictly less than 3 times of the order's processing time.
Keywords:Order Processing t On-line Strategy  Competitive Ratio t Deterministic Strategy
