摘要

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 deterministic model for the inventory policy of countries for procurement of vaccines.

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.

期刊介绍： The Central European Journal of Operations Research provides an international readership with high quality papers that cover the theory and practice of OR and the relationship of OR methods to modern quantitative economics and business administration. The focus is on topics such as: - finance and banking - measuring productivity and efficiency in the public sector - environmental and energy issues - computational tools for strategic decision support - production management and logistics - planning and scheduling The journal publishes theoretical papers as well as application-oriented contributions and practical case studies. Occasionally, special issues feature a particular area of OR or report on the results of scientific meetings.
