当顾客为两种不同类型时，考虑了具有线性成本的单产品系统。损失销售的惩罚成本不同的两种类型的客户，因此，最优系统控制需要不同的短缺概率为两类。在一种情况下，高惩罚客户独立到达，而在另一个极端，它被认为是只有一个这样的客户。单临界数策略在简单情况下是最优的。如果优先级类型的客户变得活跃，并通过改变他们的需求模式时，他们的需求没有得到满足，简单的凸性或Polya频率函数参数注册不足以保证最优策略仍然是一个单一的临界数品种。
A single product system with linear costs is considered when customers are of two different types. Penalty costs for lost sales differ for the two types of customers and; therefore, optimal system control requires different shortage probabilities for the two classes. In one case, high penalty customers independently arrive while at the other extreme it is assumed that there is only one such customer. Single critical number policies are optimal in the simple situations. If the priority type customers become active and register displeasure by changing their demand pattern when their demands are not satisfied, simple convexity or Polya frequency function arguments are not sufficient to guarantee that the optimal policy remains one of the single critical number variety.
