In order to respond to different requirements in banks, airports, hospitals and other organizations, queueing models are used to help in managing and allocating of the resources. Because we live in the pandemic of COVID-19, mass vaccination is necessary for obtaining collective immunity. For mathematical modeling of the vaccination’s process, we use a queueing system as a useful tool for estimating of the capacity requirements and service time. For that purpose, we have made simulation in AnyLogic Simulation Modeling Software. In that simulation, the processes of the vaccination and revaccination are considered. Also, the capacity of queue, the capacity of system, the average waiting time in the queue and in the system are estimated.
COVID-19 pandemic is one of the worst global disasters in the last century. Its pandemic spread and influence in everyday social life, economics and health is in central interest of concern for all governments in the world. North Macedonia is one of the countries with very high percentage of COVID-19 deaths. The health system in a few periods was before collapse. In this paper, we analyze the COVID-19 epidemic situation in North Macedonia from its beginning. We make analysis and comparisons of the situation in different time epidemic periods. We use regression models and machine learning algorithms in order to make predictions, which can be used as an efficient tool to give directions of the authorities to deal with COVID-19 challenges.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
