从单周期库存模型主要考虑的成本因素出发,通过期望损失最小法和期望利润最大法实现对单周期库存模型中缺货成本和过期成本的控制,从而确定最佳订货量。

A new information theoretic method for linear stochastic model reduction,the minimum conditional information loss approach based on state aggregation,is deduced by the principle of minimum information losswhich was applied successfully in the field of pattern recognition.

运用在模式识别领域中获得成功应用的最小信息损失准则得出了一种新的模型降阶信息论方法———基于状态集聚的最小条件信息损失方法,并讨论了降阶模型阶次的选择。
