Implementation of balance of payments calculation for railway industry enterprises based on the FRIS language

Calculating the balance of payments of a natural monopoly such as the railway transportation industry is not a trivial task. It is impossible to use existing software on the domestic market for this task, as it lacks sufficient computing power and the necessary functionality. However, obtaining an instantaneous snapshot of data on the relevant portion of the balance of payments is a crucial component for making sound management decisions for railway industry executives. This article describes how this problem was solved by employees of OCRV LLC (a contractor developing information systems) and the software tools and mechanisms developed to address it.
