Integrated Information

The role of integrated logistical support in the after-sales stages of the life cycle of construction sites is considered. It is shown that the effective management and operation of buildings and structures, their engineering equipment, is impossible without the analysis of logistical support, which is carried out at the design stage and is refined at the following stages of the life cycle of construction objects on the basis of accounting and analysis of operational information on the management of technical condition of construction. An information model of integrated logistic support for the life cycle of construction structures has been developed. It is shown that the core of the information model is an integrated information environment that contains information about the construction object, resources and processes, ensures that the data involved in the life cycle of the entity is stored and accessible. Data is added to the information environment by all participants throughout the lifecycle of the objects, allowing you to receive and analyze up-to-date project documentation and visualizations at any time. The stages of the life cycle of construction objects in an integrated information environment are analyzed.

Abstract The concept of digitalization of railway transport and the introduction of digital technologies provides for the creation of a “Digital Railway” based on a “Digital Twin”, including a “Digital Twin” of a car, which implements a number of information and organizational measures aimed at assessing the current technical condition of a real car during its operation; reducing the cost of the life cycle of the car; increasing the reliability of assemblies and parts (increasing the overhaul life); reduced maintenance costs; creation of a service maintenance system for freight cars throughout the life cycle. However, the wear of vibration damper parts is the most important parameter that determines the turnaround time, the volume of repairs and the dynamic qualities of the car, which requires more detailed and reliable scientific substantiation. The assessment of the wear of vibration damper parts (friction bar, friction wedge, bolster) is carried out in two ways - by direct examination of them in operation (in this case, wear is estimated by changing the linear dimensions, i.e., in mm over the service life) and according to the results of bench tests of models of vibration damper or testing samples on friction machines (in this case, wear is estimated by the mass of the worn-out material). The proposed method for predicting the wear of parts of frictional vibration dampers implements the Archard friction model, takes into account the variability of loads acting on the working surfaces, for which a method for determining the friction path under various driving conditions has been developed. The developed methodology makes it possible to evaluate their service interval at the design stage of the car’s running gears.

In Russia, Building Information Modeling (BIM) is becoming a mandatory requirement for the construction of new buildings. There is a positive experience in the implementation and examination of projects with BIM. A number of Russian companies have already introduced and are actively using information design technologies in their activities. However, at the current moment, the use of BIM in Russia is at the start. This paper shows examples of the use of BIM and laser scanning in the development of scientific and project documentation for cultural heritage sites. The paper shows the stages of engineering research. A comparison is made between traditional methods of building inspection and with the method of laser scanning. The key advantages of using a BIM model at the design stage, restoration and subsequent stages of the object’s life cycle are shown. The promising areas of application of BIM technologies, laser scanning technologies at different stages of the life cycle of an object (buildings, structures, utilities) have been identified.

Operating Organization

The service system for managing the life cycle of locomotives faces the problem of obtaining objective information about the technical condition of the locomotive and its operation. Designers of equipment and the locomotive as a whole, locomotive-building plants, service companies, locomotive repair plants and the operating organization have their own information systems that are not connected to each other. It is proposed to create a cross-platform management system for the locomotive life cycle database with the collection of information from all information systems at all stages of the locomotive life cycle with the appropriate management organization, which is described in the article. Information about the structure of the locomotive equipment, possible suppliers and maintenance regulations (MRO) is formed at the design stage. Information on the numbers and suppliers of installed equipment and test results is generated at the stage of locomotive manufacturing. In operation, the mileage of the locomotive, the ton-kilometer work, and, if possible, the electricity consumption are recorded. The MRO system registers the types and volumes of work, their duration and cost, and the spare parts and materials used. Equipment replacement is also registered. Separately, the reasons for failures and super-cycle work are analyzed. As a result, the database is formed for multi-factor analysis of the reasons for the low reliability of locomotives, the high cost of the life cycle. Corrective measures are being developed.
