Abstract
Large transport and machine-building holdings widely use quality management systems, one of whose main aspects is the functional safety assessment designed to identify and eliminate weaknesses in quality management and traffic safety at infrastructure facilities. The priority is to ensure the guaranteed safety and reliability of the main function, namely the transportation function. Reliability of the transportation process, that is its uninterrupted operation, is supported by a competent operation and high-quality repair of infrastructure facilities and services of third-party organizations. To ensure financial and economic stability, the level of safety in the operation of infrastructure facilities should provide for avoidance of traffic accidents, which largely depends on preventive measures aimed at traffic safety and failures of technical means during the operation of infrastructure facilities. The paper proposes an analysis of regulatory documents for assessing reliability and quality of transportation in machine-building and transport holdings. The assessment is based on the statistical data collection in the operational process of infrastructure facilities for subsequent research due to the influence of key performance indicators of infrastructure facilities and weighting factors for the rating of traffic safety functionality. The procedure analyzed in the paper implements a risk-based approach based on frequency of events and the impact of these frequencies on losses from them as the tabular coefficients. At the same time, several important coefficients do not reflect severity of consequences according to the level of violations. The correct functional safety assessment of the regional corporate governance centers, directorates and services is necessary not only to compare the results of ensuring traffic safety, but also to identify and further eliminate weaknesses in the quality management and traffic safety of transport units at infrastructure facilities.
