According to the World Health Organization, the global epidemiological situation in the first months of 2021 deteriorated. In this paper, the decision-making supporting system (DMSS) is proposed to be an epidemiological prediction tool. COVID-19 trends in several countries and regions, take into account the big data clouds for important geophysical and socio-ecological characteristics and the expected potentials of the medical service, including vaccination and restrictions on population migration both within the country and international traffic. These parameters for numerical simulations are estimated from officially delivered data that allows the verification of theoretical results. The numerical simulations of the transition and the results of COVID-19 are mainly based on the deterministic approach and the algorithm for processing statistical data based on the instability indicator. DMSS has been shown to help predict the effects of COVID-19 depending on the protection strategies against COVID-19 including vaccination. Numerical simulations have shown that DMSS provides results using accompanying information in the appropriate scenario. countries and regions, take into account the big data clouds for important geophysical and of which is based on epidemiologically verified monitoring data whose architecture is 45 represented as a multi-scale stochastic process with a detailed structure. All officially 46 recorded data cover potential COVID-19 results as statistical series, the analysis of which helps to test and predict a trend in each pandemic. Unfortunately, many efforts made by many scenarios what is most likely to happen. 86 The main contribution of this paper is how to use official COVID-19 pandemic data to 87 predict trends in virus spreading. The method is designed to create a decision-making support 88 system (DMSS) based on the sequential analysis procedure to assess the corona virus 89 transition probability between sites and the mathematical model.

Finally, the following equation describes the total number of dead individuals: Official statistics series Z= (S, I, R, D) represent typical data with deterministic and 151 stochastic components that need to introduce the instability factor J for country  to correct 152 the model results. To formalize this procedure the algorithm for evaluating these instability 153 data is proposed: PEP scenario. Figure 3 shows that in this case the changes in the pandemic outcomes stabilize depending on the vaccination level. This uncertainty also arises from the data in Table 4 273 which show the existence of countries where the effects of the pandemic are minimal. where many restrictions are considered unjustified. A confirmation of this conclusion is given 292 in Figure 6 and Table 4 .
