Review article

The article discusses the issues of further improvement of organizational and technological design of railway construction. For effective construction management provision, it is proposed to make organizational and technological decisions on the construction of facilities included in the railway infrastructure basing on the synchronization of construction flows. For the formation of synchronization methodology, the author has carried out research on the study of dynamic fluctuations in the rate of construction flows during the construction of objects, established the nature of fluctuations, and determined the spectral characteristics of the rate of construction flows. Based on the obtained results, it is proposed to form an inter-nodal construction flow (as the most resistant to destabilizing factors) that would solve the problem of synchronization of rates and provide the highest probability of achieving the directive rate of the complex flow of railroad construction. The choice of priority rates of construction flows of various levels is made using variants of the typical hierarchical structure of the construction rates of the railway in question.
