Information aspects of security in transport: Analytical calculations

In the third article of a series, devoted to the description of the decision support system in the field of ensuring the safety of passenger traffic and countering illegal activities in transport, the conceptual model proposed in the first article of a series and supplemented by the basic functional content in the second article of a series is expanded with specialized analytical statements. Firstly, a set of formal concepts is formed that provide the possibility of transforming the operational tasks of the system users into computational tasks for the selected transport data. Then, a series of computational problems is presented that provide information support for the analyst of the subject area in solving operational problems, analyzing incidents, and conducting situational analysis. Finally, a planned presentation of analytical functions associated with complex data processing is announced.
