The countries are the units that procure the vaccines during the COVID-19 pandemic. The delivered quantities are huge. The countries must bear the inventory holding cost according to the variation of stock quantities. This cost depends on the speed of the vaccination in the country. This speed is time-dependent. The vaccinated portion of the population can be approximated by the cumulative distribution function of the Cauchy distribution. A model is provided for determining the minimal-cost inventory policy and its optimality conditions are provided. The model is solved for 20 countries for different numbers of procurements. The results reveal the individual behavior of each country.

这些国家是在 COVID-19 大流行期间采购疫苗的单位。交付数量巨大。各国必须根据库存数量的变化承担库存持有成本。该成本取决于国家的疫苗接种速度。这一速度与时间有关。人口中接种疫苗的部分可以用考奇分布的累积分布函数来近似表示。提供了一个用于确定最低成本库存政策的模型，并提供了其最优条件。该模型针对 20 个国家的不同采购数量进行了求解。结果揭示了每个国家的个别行为。

A robust optimal control of discrete time Markov chains with finite terminal T and bounded costs or wealth using probability distortion is studied. The time inconsistency of these distortion operators and hence its lack of dynamic programming are discussed. Due to that, dynamic versions of these operators are introduced, and its availability for dynamic programming is demonstrated. Based on dynamic programming algorithm, existence of the optimal policy is justified and an application of the theory to portfolio optimization along with a numerical study is also presented.

本文研究了利用概率变形对具有有限终端 T 和有界成本或财富的离散时间马尔可夫链进行稳健优化控制的问题。本文讨论了这些畸变算子的时间不一致性及其动态编程的不足。因此，引入了这些算子的动态版本，并证明了其在动态编程中的可用性。在动态编程算法的基础上，证明了最优政策的存在，并介绍了该理论在投资组合优化中的应用以及数值研究。
