【摘要】 经典的在线租赁只考虑购买和租赁两种决策行为,当在线租赁方购买设备后,不允许退货。本文假设在线租赁方在选择购买设备后,如果觉得购买设备不划算,可以在任何时候花费一定的代价把设备退还给承租方。通过定义退货费用函数来刻画退货行为,本文提出了可退货在线租赁问题,它是经典在线租赁问题的扩展。利用传统的竞争分析方法设计了该问题的竞争策略,分析了策略的竞争性能,并证明该策略能达到竞争比下界(即是最优竞争策略)。同时,在风险回报竞争分析框架下,进一步讨论了上述问题,得到了给定预期和风险下收益最优的竞争策略。更多还原

【Abstract】 The classical online rental problem only considers two options: buy or rent.This paper assumes that the buying-permission can be canceled,and proposes the online rental problem with canceling buying-permission.The proposed problem is a generalization of the classical online rental problem.Using the method of traditional competitive analysis,we design the optimal investment strategy for this problem.Moreover,we also give the optimal strategies under the risk-reward framework.These results can provide a basis for further constructing the framework of the online leasing problem based on contracts.更多还原
