【摘要】 由于电子商务的快速发展,基于Internet 的招投标决策与拍卖已成为国际决策分析学术界激烈竞争的一个研究热点。许多与决策分析理论和方法相关的问题在网络环境下都需要重新开展研究。文章在对在线多数量序贯拍卖模型研究之前,对在线拍卖的一些特点作了分析,并对前人的在线多数量拍卖文献进行很好的总结;然后对前人在模型研究的内容上做了进一步的完善。文章共分为五个部分,研究内容分别如下:第一部分介绍了研究的背景和研究内容,为本文的结构思想做了准备;第二部分根据文章研究所需要的基础理论,分别对电子商务、拍卖与招投标理论以及在线拍卖进行了介绍;并总结了前人的研究成果,分别对国内和国外学者对多数量拍卖的研究成果进行了综述。第三部分首先针对本文研究的内容,引入在线多数量拍卖流程示例,对在线拍卖成本做了分析和介绍;然后文章按照研究内容的需要,把在线多数量序贯拍卖模型分解成单阶段拍卖模型和多阶段拍卖模型,再对单阶段确定型在线多数量拍卖、单阶段随机型在线多数量拍卖进行分析和研究。第四部分把多阶段拍卖分为多阶段确定型在线多数量序贯拍卖和多阶段随机型在线多数量序贯拍卖依次进行分析和研究,其中对前人的多阶段拍卖模型在拍卖库存成本参数做了完善性的工作,并对多阶段随机型拍卖模型做了推导和分析。文章最后对全文进行了总结并对未解决或需要进一步研究的内容做了展望。更多还原

【Abstract】 With the development of electronic commerce, namely EC, auctions and bidding based on Internet have got one of competitive studies on international decision-making and analysis. Many problems about decision-making and analysis and methods are restudied under the circumstances of Internet. Before online multi-unit sequential auction models, characteristics of online auctions are described and the former works are summed up. Even the latter perfects online multi-unit sequential auction models.The dissertation is consisted of five chapters as follows. The first introduces its backgrounds and contexts for its development later. The second shows the basic theories about EC, auctions and bidding and online auction. Furthermore, it sums up internal and overseas conclusions of multi-unit auctions. The third gives an example of auction process to help understand, introduces and analyzes online auction cost. Afterwards, online multi-unit auctions are decomposed of one stage model and multi-stage model to satisfy analyzing and studying. And then, are studied one-stage deterministic online model and one-stage stochastic online model. The fourth analyzes and studies online multi-unit auctions decomposed of multi-stage deterministic sequential online model and multi-stage stochastic sequential online model, which are intuitionistic and more easily understand auction cost that examples explain. Among these models, some are restudied because of modifying other modeling parameters and the multi-stage stochastic sequential online model is deduced. The last concludes dissertation and lists contexts studying in the future.更多还原
