In the process of research, the sequence of construction and the overall structure of the enterprise management system, based on the use of cloud technologies, are determined, which allowed to build a mathematical model for calculating the probability of making an error-free decision, evaluating the efficiency of decision-making, a model of making a management decision for a certain time with the parallel method of operation of elements of the enterprise management system. %U https://jitm.ut.ac.ir/article_76293_2b4c5c48f6fcfbc80da9425d1aaea160.pdf
