摘要
在国内汽车租赁业逐步发展的时期,本文研究了可进行二手交易的汽车的租赁问题。基于占线算法与竞争分析理论,设计了考虑交易成本、用车费用及汽车折旧的最优确定性占线策略并得到了常数级的竞争比。后进一步改善模型,引入风险预测,设计了风险占线策略。将预测不成功的占线策略与最优确定性占线策略进行比较,得到了较好的结果。
In the period of gradual development of the domestic car rental industry,this paper studies the problem of secondary trading value car rental.On account of the theory of online algorithm and competitive analysis,we design a optimal deterministic online strategy and constant competitive ratio considering transaction costs,car costs and car depreciation.After that,to improve the model,we design an online risk strategy and obtain a better consequence comparing the unsuccessful online risk strategy with optimal deterministic online strategy in the light of forecasting.
