Calculating skill on the distribution of2 - dimensional continuous random variable functions 二维连续型随机变量函数的分布计算技巧
The approximation of exponential distribution on the sequences of dependent nonnegative continuous random variable 指数分布对任意非负连续型随机变量的逼近
Differing from the two assumptions , the problem is studied further taking the replenishing interval as a continuous random variable in cyclical replenishment 笔者在不同于以上两个假定条件下研究多阶段存贮问题,周期补货但补货间隔取为连续型随机变量。
In this paper , the optional model on the seasonal order of goods when the demand is a continuous random variable is set up and is simply illustrated in practice according to maximum expected profits 从供求关系的角度,考虑预期利润最大,建立了需求为连续型随机变量时的阶段性货物订购的优化模型,分别得到了与存贮费用有关、考虑缺货损失以及多阶段订购毋需订购费用时的最优进货量。
