Abstract: The paper considers an approach to the description and analysis of transport multi-operation technologies based on the use of operator schemes and allows studying their structural properties (changes, reconfigurations, parallelism). The relevance of the development and use of formalized graphical tools for describing and analyzing transport technological processes is shown. A set-theoretic operational-event model of technologies and processes is presented. The questions of its interpretation by operator schemes, including operations, input and output resources, control and resource connections, space and time coordinates are considered. General characteristics of operator schemes are given. Classes are defined, and examples of coordinate, algorithmic, asynchronous and combined schemes are given. The reasons and sources of parallelism and changes in railway technological processes are described. The paper deals with the analysis of changes and reconfigurations of technologies and processes using operator schemes. The relationship between the parallelism of multi-operation technologies and reconfigurations of technological processes is established. The paper shows the significance of the study of internal parallelism of technologies and ways to identify it based on models of parallel computing-the augmented Bernstein - Russell - Narinyani theorem, tiered parallel schemes and trigger functions. A number of statements and conclusions are made about the prospects of using operator schemes to study configurations, reconfigurations and parallelism of technologies and processes in order to improve the efficiency of transport systems.
