The concept of computer-aided design of railways in the information and digital environment

The main objective of this work is the need to develop a new technology for automated solution of railway design problems in the information and digital environment.

For this purpose, the methodology of structural system analysis, the theory of systems, and the principle of decomposition are applied. A brief analysis of the terms related to informatization and digitalization is given, and the interpretation of the concept of “information and digital environment” in relation to the tasks of railway design. The key concepts of information modeling of construction objects in the current regulatory documentation of the Russian Federation, the main qualification features and advantages of information modeling technology are given.

Based on the results of the analysis of the structure and functionality of existing computer-aided design systems of railways and highways, the sequence of procedures of the existing technology of computer-aided design of roads is determined. The concept of automated solution of railway design problems in the information and digital environment based on the use of information modeling technologies and mathematical optimization methods is proposed. The concept is represented by a functional hierarchical model of a computer-aided design system. For its development, the Data Flow Diagrams functional modeling tool was used.

The proposed concept is the basis for the development of a computer-aided design system, which will allow the implementation of a new technology for computer-aided design of railways, reduce labor costs and deadlines for the development of design solutions, improve their quality and efficiency.
