The article provides a critical review of the research topic under consideration in the context of the principles laid down in the concept of the fourth industrial revolution. Attention is paid to “value chains”. Value chain is a new form of justifying the processes of product development, production and structuring of measurement operations. The formalization of a hybrid control measuring system of a new generation, combining the principles of integration of information security, information technologies and the mathematical apparatus of graph theory and set theory is given. The importance of artificial intelligence methods in the control, commissioning and operational monitoring of dynamic measurements in automation systems and mechanical engineering in the framework of Industry 4.0 is substantiated.

The article is dedicated to the issues of development of expert systems in data-processing networks during web programming. The dependence of the processing, storage and transmission of information and web applications on the uniqueness and problematics of expert systems creating is observed. The process of development of a software control block of content (engine) as the own control system is considered in details; vulnerabilities and a set of necessary functions inherent in the specified engine are explored. Each new developed software engine can be exposed to unauthorized access and content theft, in this regard, sometimes it is worth considering the percentage of uniqueness of the development methodology and code. In this case, the control block (engine) must be written using its own unique variables and file names, which will help secure the site from third-party interference and will not require the purchase of more expensive hosting for its placement. In addition, the article investigates the problems associated with the threat posed by malicious programs in computer networks, such as direct DDOS attacks, identifies the features of such programs, and also provides ways to combat them.

The concepts of universality and general applicability of information networks as well as the issues of using networks in specific directions are considered in the article on the example of the convergence of transport infrastructure and information networks. An analysis of modern information networks has been carried out and the following three main directions have been identified: infrastructure as a service, platform as a service, software as a service. The article examines the issues of automation of the customer relationship management by introducing a CRM system in order to improve transport support and logistics services provided by companies at the competitive market of logistics services. The basic principles of convergence of information networks and transport infrastructure are presented on the example of a transport and logistics system. The issues of use of the modern information technologies for continuous monitoring of transport infrastructure are considered.

The growth of traction current leads to losses of electrical energy in the traction rail network, which entails losses for railway companies, including the Russian Railways holding. Additional losses arise due to the deterioration of the resistance of the elements, which occurs in a shorter time in terms of sections on which the movement of trains of increased mass and length is not carried out. Equations for estimation of the power and electrical energy losses in the DC traction rail network have been obtained. These equations are applicable both for the calculation at the sections of the circulation of freight trains, the mass of which does not exceed the weight norm established by the schedule on the route of this train, and taking into account the correction for the passage of long and heavy trains. A simulation model that makes it possible to assess the power losses in a section of a traction rail network depending on changes in the resistance of both individual elements and entire groups that make up the traction rail network, as well as to analyze the effect of the transition resistance rail-ground on the magnitude of leakage currents has been prepared. The need to constantly maintain the elements of the traction rail network in a working condition is determined. It is explained by a significant increase in losses in electrical energy when passing trains of increased weight and length, even with minor deviations of the resistance values from those established by the regulatory documentation. To maintain an operable state and reduce the likelihood of the appearance of faulty elements of the traction rail network, entailing the loss of electrical energy, it is proposed to develop automated monitoring systems for the traction rail network, which ensure the adoption of decisions on the need for maintenance or repair of an element of the traction rail network and transmit information about this repair personnel on duty.
