开放式逢低买入中买家数量确定的投标决策

Bidding Decision on Open Group-buying Online Auction with the Certain Number of the Bidders

逢低买入是一种新型的在线动态价格机制。本文以B2B开放式逢低买入拍卖为研究对象，在买家数量确定且独立投标的条件下，将已有的针对两个价格水平下买家最优订货决策拓展到更复杂的多个价格水平的最优订货决策问题。本文提出的零售商投标决策定理，不仅满足了买家的实际需求，也提高了决策的实用性。

Group-buying online auction （GBA） is a new kind of dynamic pricing mechanisms. This paper analyzes the bidder＇s optimal decision with the case that each bidder bids independently based on the B2B open group-buying online auction with the certain number of the bidders. Compared to the bidding decision under two-price levels, in this paper, we propose bidder＇s optimal bidding decision under multi-price levels which is more complicated and not only satisfies the bidders＇ actual demands, but also improves practicability of the decision.
