    The article considers the principles of building the analytical and simulation model of the human operator and the industrial control system hardware and software. E-networks as the extension of Petri nets are used as the mathematical apparatus. This approach allows simulating complex parallel distributed processes in human-machine systems. The structural and hierarchical approach is used as the building method for the mathematical model of the human operator. The upper level of the human operator is represented by the logical dynamic model of decision making based on E-networks. The lower level reflects psychophysiological characteristics of the human-operator

Therefore, working with such large amounts of data requires the development of specialized software for design engineers. The construction of algorithms, the development of methods, the creation of mathematical models for searching, comparing and copying large heterogeneous related data, as well as the implementation of the obtained scientific and practical results in the software package of the design engineer of the onboard software of spacecraft. Results: mathematical models of comparison operations are developed in terms of sets and logic of predicates, criteria for evaluating comparison results are determined. On the basis of mathematical models, software components have been developed that provide search, comparison and copying of parts or a complete architectural project of the spacecraft onboard software. The developed software components are integrated into the software package for computer-aided design and maintenance of the spacecraft onboard software. Practical relevance: the results of the work are implemented in JSC β€œInformation satellite systems named after academician M. F. Reshetnev” and are practically used in the design of new satellites of the same type series. The complexity of working with heterogeneous big data did not allow to fully implement the copy operation. The paper proposes to introduce the concept of a two-phase copying operation, when the first phase copies the structure of the onboard software, and the second phase links the structure with the resources of the spacecraf
