摘要: 运用在线问题与竞争分析的方法研究了购买价格递减的在线租赁问题。通过揭示相关费用函数的性质,先后给出了最优离线策略以及在线策略。通过竞争比分析,证明了我们给出的在线策略是该问题唯一最优策略,而且该策略的竞争比随购买价格的优惠率的增加呈严格递减趋势。竞争分析结果表明考虑购买价格递减因素能够改进在线策略的竞争比从而提高决策效率。

Abstract: In this paper, we use the method of competitive analysis for online problem to study an online leasing problem with decreasing price for purchasing. By analyzing the properties of cost functions concerned, the optimal offline strategy and an online strategy are given. By way of the analysis of competitive rate, we prove online strategy to be the unique optimal strategy for this problem, and competitive rate of this strategy is strictly decreasing with the preferential rate of purchasing price. The result shows that taking the factors of the decreasing of purchasing price will improve the competitive rate of online strategy and thereby increase the decision-making efficiency.

Key words: online leasing problem, online strategy, competitive analysis, competitive rate, decreasing purchasing price
