摘　　要：随着经济管理中发现越来越多的在线问题,运用竞争算法分析也越来越受到人们的普遍关注。对于在线租赁问题,由于其需求结构简单且具有良好的统计性质,另外考虑到税率也是影响在线租赁决策的一个重要因素,本文运用竞争算法方法建立了需求具有线性指数危险率特征的在线租赁决策模型,并得到了最优的竞争策略及其竞争比。With lots of online problems found in economic management, more and more scholars take an interesting attention on analysis method of competitive algorithm to solve online problems in recent years. For on-line leasing problem, because of its simple demand structure and the good statistical properties, we use competitive analysis method to built online leasing model with linear exponential hazard function under taking it into account tax rate that takes an important play in affecting online leasing decision-making. Finally, optimal competitive strategies and their competitive ratios will be given out by competitive analysis.
