针对占线拍卖问题(on-line auction problem)的卖方策略进行了研究,扩展了传统占线拍卖机制中拍卖人风险规避态度的假设,构建了基于风险偏好的风险回报分析框架。进一步,为拍卖人设计了RPS拍卖策略和MPS拍卖策略,结论显示这两种拍卖策略使得拍卖人可以根据自己的风险偏好和对未来的预期进行拍卖数量、拍卖价格的选择,而且两种拍卖策略的竞争性能比优于传统竞争分析框架下的结果。数值算例的分析表明,在风险回报分析框架下,拍卖人的风险忍耐度与拍卖策略的收益成正比。分析还显示,设置多个预期参考价格可以增强拍卖人预测能力,从而提高拍卖策略收益。
This paper studies the strategy of sellers on the on-line auction problem, extends the assumption of the buyer’s risk aversion in the traditional auction mechanism, and constructs a risk-return analysis framework based on the risk preference. Further, RPS auction strategy and MPS auction strategy are designed for the auctioneer. The conclusion shows that the two auction strategies enable the auctioneer to choose auction quantity and auction price according to their own risk appetite and anticipation of the future. Moreover, two auction strategies The competitive performance is superior to that of the traditional competitive analysis framework. Numerical analysis shows that under the framework of risk analysis, the auctioneer’s risk tolerance is proportional to the return on auction strategy. The analysis also shows that setting multiple expected reference prices can enhance the auctioneer’s ability to forecast, thereby increasing auction strategy revenue.
