MODEL OF STATISTICAL AND AUTOCORRELATION ANALYSIS AND ECONOMIC MODEL OF CARDIAC PERIOD VARIABILITY USED IN ORTHOSTATIC TEST UNDER CHANGING CLIMATE IN DIFFERENT ETHNOIS IN THE MAN-MACHINE SYSTEM
Relevance of the topic. The authors have developed a mathematical and economic model of artificial intelligence of variability. The model is usedfor orthostatic testing of operators in the man-machine system. The authors conducted research in a changing climate. The authors studied representatives of different ethnic groups of sailors. Research methods. Variable, mathematical statistics, spectral analysis, cybernetic, artificial intelligence, physiological. The scientific novelty of the work lies in the creation of a mathematical supermodel for artificial intelligence, working for a changing climate according to the cardio intervals of the orthostatic test of different ethnic groups. Practical significance. The developed model made it possible to process many indicators of variability in the optimal time in the mode of using artificial intelligence, which itself processes the data, analyzes the data, and gives the result. Research results. Studies were conducted on groups of different ethnic groups and differences were found in the variability indicators for them. Economic model. The developed economic model has shown economic efficiency when using variable methods to identify the physiological state of seafarers
