Abstract

The article presents the results of analysis and theoretical generalization of scientific works, which consider the problems of a functioning automated railway system. Management of freight transportation of Ukrainian railways no longer exists without the use of automated systems. It can be stated that all technologies that are developed and implemented in management processes are implemented only in the information environment. In particular, accounting of divisions and the entire railway, calculation of quantitative and qualitative indicators of divisions and the entire railway in general, financial and accounting reports, technological documents, settlement documents for the provision of services and more is in the information base - the only automated freight management system Ukrzaliznytsia. Information about events with control facilities is transmitted from automated workplaces of railway employees to the central database on the transportation process of the automated freight management system of Ukrzaliznytsia, where it processes, stores and forms separate models of the transportation process. These models are virtual. A set of models of the transportation process (information images of control objects) is considered, which is a logical database that ensures the unity of the information environment of the automated freight management system of Ukrzaliznytsia. The consolidation of all data of the automated freight management system of Ukrzaliznytsia to standard models and connections between them provides integration of all data of the system, which allows to choose any combination of data of different objects connected by different connections; the fundamental openness of the database to add a new model to the databases has little effect on the functioning of existing ones; universalization of processes of writing and reading of data from models, and also facilitates their maintenance. Regulatory and technological documents differ significantly from real situations and operating conditions. The dispatching apparatus is often forced to make decisions in unexpected situations and in conditions of uncertainty. The task of the development of the IT space of the railway is to develop and implement technologies for operational management, the creation of systems to support the decision of the dispatching apparatus on the management of technological processes.

У статті наведено результати аналізу і теоретичного узагальнення наукових праць, у яких розглядаються проблеми функціонуючої автоматизованої системи залізниці. Розглянуто множину моделей перевізного процесу (інформаційних образів об’єктів управління), яка складає логічну базу даних, що забезпечує єдність інформаційного середовища автоматизованої системи керування вантажними перевезеннями Укрзалізниці (АСК ВП УЗ-Є). Нормативно-технологічні документи суттєво відрізняються від реальних ситуацій та експлуатаційних умов. Приймати рішення диспетчерський апарат часто вимушений у неочікуваних ситуаціях і в умовах невизначеності. Завдання розвитку ІТ простору залізниці полягає у розробленні та впровадженні технологій управління оперативною роботою, створенні систем підтримки прийняття диспетчерським апаратом рішення щодо управління технологічними процесами.
