摘要
利用多方案投标报价统计中标数据,按数据库因果关系预测中标结果可获得最小损失下的最优决策。为克服数据库因果关系条件概率矩阵维数灾,将因果关系转化为线性多项式,可使计算简便。实例计算表明,线性化近似效果良好。
Multiple schemes bidding can be used to count data of successful bidder.The optimal decision based minimal loss is obtained by forecasting bid winner on the basis of causal relationship in database.To overcome dimension curse of conditional probability matrix,casual rules in databases is converted to linear polynomial,which makes calculation simple.Finally,the method is applied to a practical project and the results are satisfactory.
