摘　　要：以往的在线租赁研究基于Karp提出的"雪橇租赁"模型,其假设当租赁方购买设备后不允许出售。研究了存在二手货市场的在线设备租赁问题,即购买的设备可在二手货市场上出售。讨论了设备在二手货市场出售价格为2种不同情形下问题的竞争策略。第1种情形,出售价格围绕购买设备的剩余价值(购买价格与价值损耗量之差)上下波动,分析了问题的离线最优解,并证明不存在具有常数竞争性能比的租赁策略。第2种情形为第1种情形的特例,其出售价格完全由购买设备的剩余价值决定,给出一个租赁策略,并证明了该策略为最优策略,其竞争比小于Karp"雪橇租赁"模型中最优策略的竞争比。The traditional online rental problem is based on Karp＇s ski-rental model,with the assumption that the equipment cannot be sold after purchase.In this paper,the online decision maker can sell equipment in a second market,The competitive strategies of two different selling price cases are discussed.In the first case,the selling price fluctuates around the surplus value.For this case,we give an optimal off-line solution,and prove that the online rental strategy with a constant competitive ratio does not exist.In the second case,the selling price is completely determined by the surplus value.For this case,we propose an optimal online rental strategy,and the competitive ratio of the proposed strategy is less than the optimal strategy in Karp＇s ski-rental model.
