Verifiable Structure of Technological Processes in Dynamic 3D Models of Railway Stations

The article is devoted to the study of technological processes at railway stations reproduced in a threedimensional model from the standpoint of assessing reliability of the development of those processes. The identifiable simulated and virtual processes are matched against specific comparative positions. The benchmark is a fixed set of technological series of operations for processing wagon flows of all categories at a particular railway station. To provide adequacy of model reconstruction to the prototype, the emerging waiting time and downtime of rolling stock are considered, which are introduced into the model as special split states of main spatial locations of rolling stock. The concept of «paraphysical structures» is introduced into the developed model of the station, which comprises any conditions impossible according to physical canons and irrational according to technological requirements regarding the objects of track development and rolling stock. The logic of program control over similar states of modelled structures is based on the analysis of the allowed positions of station objects when performing reference technological operations. Slowdown in station operations can be a forerunner to waiting or downtime. An important methodological basis for the technique for developing a dynamic model of a station includes formation of a system of internal program analysis of the current situation, recognition of the moment of occurrence of a paraphysical situation and its anticipation by transforming it into normally developing standard situation. The adapting module of the information prototyping environment should be an intelligent agent with developed ability of generating exceptional situations based on comparative tests conducted by it, of developing an appropriate knowledge base and of using it in the process of further operations without any external users’ participation. The objective of the study, described in the article, is associated with dev elopment of general requirements for a dynamic model of a railway station, functioning adequately to a real technical system due to assessment of reliability of reproduced station technological processes.
