In the conditions of digitalization, the influence of the adverse human 2 factor in the production system is minimized, and a person gets the opportunity to 3 engage in creative activities rather than routine ones and work in more comfortable 4 conditions, that is, in parallel with technocentricity, human-centricity is formed in 5 industries. IPU RAS has developed a methodology for modeling the process of tech6 nological preparation of flexible production of various products (including automatic 7 machines) in various production conditions, taking into account the probabilities of 8 high-quality technological operations. It is noted that flexible production can be real9 ized only in conditions of digitalization. The proposed methods and algorithms can 10 flexibly adjust to different production conditions and help the technologist decide on 11 the possibility and expediency of putting the product into production. As a further 12 development of this methodology, the relevance of the scientific problem of creating 13 a unified formalized approach to studying the process of organizing human creative 14 work in flexible industries is substantiated. It is shown that one of the components 15 of the formalized description is the probability of the targeted use of working time, 16 which is proposed to be determined using the results of population surveys.
