PARALLEL DATA PROCESSING IN AUTOMATED RAILWAY TRANSPORT DISPATCHING SYSTEM

Аннотация

Abstract.

The article is devoted to the following tasks. There is a substantiation of the need to solve the problem of increasing the efficiency of automated dispatching control systems (ADCS) of the rolling stock (RS) movement of railway transport, in particular high-speed (HSRT) by applying a technology that involves paralleling of calculations in the ADCS subsystems that implement coordination of RS movements. There were substantiated the principles of RS division into groups. It is shown that this separation will increase the speed of the calculations, especially in situations where time constraints are imposed on obtaining results in the ADCS. There is proposed an algorithm that allows for the subsequent stages of the research to implement programmatically the solution of tasks related to the coordination of movement and PS graphics. Unlike existing solutions, the proposed algorithm takes into account the possibility of using parallel computing technologies. There is also proposed a mathematical model that reflects the principle of separation of computational processes for the purpose of their execution in parallel mode. There was carried out a preliminary assessment of the effectiveness of the use of parallel computing technologies in tasks solved by ADCS. In particular, there are considered tasks that involve solving problems related to the RS coordination of a railway transport, including high-speed railway transport of the Republic of Kazakhstan.
