Based on rum ( random utility maximization ) logit model is disaggregate method in modern traffic planning theory . because of small investigating capability with accurate prediction logit model is valuable in mode - split research Logit模型是基于最大效用原则的离散选择模型。由于其不需要很大的调查样本却同样能提供较准确的分类信息,它在交通方式划分研究上有着广泛的应用前景。
The third analyzes the definition of fraud of a letter of credit in law both domestic and international , the types of fraud , the general character of fraud , and the exception to the independence principle of fraud . then i will discuss the issue of utility maximization between " independence principle " and " exception to the independence principle " with the methods of evaluating maximum value and case study 第三部分分析了信用证诈骗在国内外法律上的界定,诈骗的类型,诈骗的共性,诈骗的“例外原则” ,然后通过求最大值的方法并结合案例谈了“独立原则”与“例外原则”的效用最大化问题。
Further , because of these problems in online auctions , such as “ slamming ” , “ winner ’ s curse ” , it easily result in decreasing the rate of customer ’ s satisfaction ; and the transaction time always was set up long as soon as possible for assurance to attract more auctioneers and their utility maximization , which easily result in higher auction costs 而网上单向拍卖存在的“狙击手” 、 “网下窜谋” 、 “赢者诅咒”等问题,容易降低用户的满意度;此外,为保证吸引更多的竞拍者参与,使拍卖者获得最大化效用,网上单向拍卖通常设置较长的拍卖时限,且买家加价频繁,容易导致电子商务额外成本的增加等问题的发生。
Following this idea , considering the serious information asymmetry and personal expect utility maximization in the double auction , we intends to construct a bidding model on bayesian nash equilibrium based on incomplete information games , consequently obtain a solution on each private values and maximum forecast price and minimum forecast price on the marketing . then , we analyze in detail the characters and possibilities of the offer strategy by means of computer simulation according to the experimental economics 在此基础上,考虑到双向拍卖中存在的信息严重不对称和个人期望效用最大化,构造了该拍卖模式中基于不完全信息博弈的贝叶斯纳什均衡模型并求解,获得一个关于各自估价和市场最高及最低预测价格的线性函数的报价策略。
