【摘要】 网上拍卖是电子商务的一个重要组成部分,也是近年来理论研究的热点.以国际著名拍卖网站Priceline的预定机票业务为背景,从买方和卖方两个角度分别建立数学模型,对模型进行分析,并证明了关于买方模型的一个定理:买方的估价越高,其报价越高.最后通过遗传算法对两个模型进行数值求解.更多还原

【Abstract】 Online auction is an important part of e-commerce, and has been the focus of many scientific researches. Three steps are followed in the case study on online auction. First, based on the reservation of airline tickets in Priceline, some assumptions and descriptions of buyers, sellers and transaction rules are made. Second, the models for buyers and sellers are analyzed separately, with emphasis on how to maximize expected utility for buyers and how to minimize expected gain for sellers. Finally, both models are studies and a theorem is thus proved: the more the valuation of a buyer is, the more his bid will be. The numerical results are obtained through the application of genetic algorithm.更多还原
