Abstract
The article focuses on the presentation of graphical models for managing organisational and technological processes of maintenance and repair of line-dispersed facilities in the form of information flow operograms as tools for assessing the reliability of organisational and technological processes within the framework of the activities of the infrastructure management center of the Central Infrastructure Directorate of Russian Railways. At this stage of research, the main attention is focused on the methodology for assessing the efficiency of infrastructure complex management that makes it possible to reduce losses from reducing the influence of the human factor.
The purpose of this study was the graphical modeling of information processes of maintenance and repair of railroad infrastructure elements. The structure of graphical models in the article is presented in the form of a graph with a set of vertices and a set of arcs symbolizing performers and information links between them. Information flows circulating in the system are assumed to obey Poisson's law, and the time of their processing is assumed to obey the exponential law. The algorithm of modeling of information processes consisting of eight positions is offered: justification of the graph of information interrelations of operations on management of revealed failures of technical means of railway track; description of the graph by the system of differential equations; modeling of information flows; analysis of probabilities of fulfillment of operations and cycle of management of revealed failures; calculation of the coefficient of loading of participants of structural divisions; change of their number and continuation of modeling of information processes. The procedure of formation of the information flow of detecting failures by a track measuring car and the sequence of decision-making on their elimination is outlined. The proposed approach makes it possible to apply the method of optimizing the duration of restoration work and assess the organizational reliability of technological processes of current maintenance and repair of railroad infrastructure facilities.
