Objective: Formulating proposals for improving the indicators of infrastructural and technological interaction when assessing multivariate management decisions in the regional railway system on the example of the “port station – port” system. Methods: Drawing on the analysis of publications in the given research area, a modifi cation of the methods of the theory of fuzzy sets and the theory of probability was applied to select and formalize the most important transport and technological processes of port stations, taking into account possible stochastic phenomena in the management of the interaction between the station and the port. Results: The theoretical substantiation of the degree of belonging of the axiom of station transport and technological processes to certain conditions of interaction between the station and the port, the relationship of their association and inclusion is obtained. A matrix of links between the main technological operations and infrastructural elements for a specifi c port station has been developed. An example is presented and the axioms of transport processes of options for servicing port berths are described. Approaches to the assessment of logical situations and fuzziness of subsets of parameters of transport processes in the control of the interaction between the station and the port are formulated. In the environment of the analytical computing system, the time parameters of the options for organizing transport processes are determined. Practical importance: The visualization of the fuzzy organization of transport sub-processes was performed, the degree of logical correspondence between the axiom of station transport and technological processes and their entropy were assessed, a diagram of the membership of a set of times of transport process variants was constructed, which allows taking into account poorly formalized processes in managing the operation of the “port station – port” system and, in the future, reduce local cars inactivity in the system.
