BACKGROUND: The pace of transport system development not corresponding to current demands of a town is a significant obstacle on the way of achieving target values of business activity and quality of life. One of the main indicators of quality of life in a modern large city is satisfaction with city public transport. The backbone mean of public transport in Saint Petersburg is underground which efficiency indicators are share of accomplishment of train schedule and accomplishment of stations’ operation schedule. However, funding based on subsidies and requirement of proper fulfillment of given efficiency indicators make the Petersburg Underground SUE look for new ways of adaptation of planning and control processes for managing available resources ensuring keeping outdating infrastructure operable and cost reduction based on state-of-the-art informational technologies.
AIMS: Establishment of enlarged hardware facility and basic structural solution necessary for unrolling software for planning and control of maintenance of the underground’s escalator park. The study object is the underground’s escalator park; the study subject is automation of maintenance system.
METHODS: In the first part of the paper, as a result of statistical compilation and comparison of homogeneous data from annual reports of the Petersburg Underground SUE in the tabular form as well as analysis of qualitative and quantitative indicators of the escalator park considering the information on the history of maintenance system formation, the statement was made about existence of interaction between the changes taking place in the city transport system and demands of adaptation of processes of planning and control of operations in the escalator park maintenance system. In the second part of the paper, on the basis of analysis of regulatory framework and requirements to development of data processing centers, the main structural element for implementation of facility of planning and control of performing the underground’s escalator park maintenance was established.
RESULTS: The theoretically valuable result of the study is the found interaction between changes taking place at the level of the city transport system and demands in changing the underground’s escalator park maintenance system for achieving the comprehensive evolution of the transport system. Meanwhile, the basic structure of the hardware-software facility, main structural element of which is the corridor isolation system implementing the tool of adaptation of processes of planning and control the operation, is significantly valuable for practical use.
CONCLUSIONS: Structure and equipment of the hardware-software facility as well as the installed software for monitoring, planning and control of the operations ensuring/not ensuring fulfillment the efficiency indicators give the opportunity to transfer the infrastructure parts from the running hours-based maintenance system to the state-based maintenance system.
