The article deals with the survey of transport and operational condition of the highway R224 " Samara-Orenburg in which it was found that the roadway surface is in poor condition due to the presence of transverse cracks, ruts and pits. In a survey of 5 existing culvert structures were identified unacceptable defects in the structure. Based on the foregoing, the specified section of road be repaired in accordance with GOST R 50597-2017 “roads and streets” . Currently, economical and mobile methods of inspection of road structures are of particular relevance. Conducting engineering surveys of the GPR system MIRA was determined the constructive layers of road clothes light. The decision on milling to a partial thickness of the pavement that runs recyclers WR 4200, with the subsequent device of asphaltgranulate type To

The modern market of goods and services is developing dynamically, which creates a need for new technical solutions that can meet changing needs. One of the main ways to increase the efficiency of commercial activity is the automation of processes and their interaction. The article describes one of the possible approaches for solving the problem of automation in the field of automation of business processes in the drug trading system. As such a solution to the task of automating business processes arising in the field of trade in pharmaceuticals, the AptekaPro information system was proposed. This article provides a detailed description of the system, its structure and principles of operation. A description of the main modules of the system and their purpose is given. It describes the main advantages that can be achieved as a result of the introduction of such information systems into commercial activities.The article was published as part of the implementation of the program of the International Forum "Victorious May 1945".

This article presents the results which purpose of cases of intentional distortion of "objective" ratings based on individual indicators. The aim of the study was to build an algorithm for determining unfairly placed places in the ranking as a result of manual adjustment. The main tool is the identification of the weight coefficients of private ratings with a known form of the functional dependence of the overall rating. The analysis of techniques of creation of one of popular Russian ratings was for this purpose carried out, mathematical models of dependence of the general rating of higher education institution on its private ratings are received. It was revealed the presence of subjectivity in the construction of the rating, which manifests itself in the form of an unfair score. Standard methods do not allow to reveal such non-random "emissions" and do not provide an objective assessment. The offered algorithm allows to find such "emissions", to exclude them from selection and define fair values. The offered algorithm can be useful for heads of universities to check the correctness of the occupied place in the ranking of their organization and understanding of their real position among other universities.

This study describes the method of narrative management of the socio-economic system. The stages of narrative management and the structure of the business process are presented, as well as the distribution of responsibilities among the participants of the management process. The system of support of narrative management in the socio-economic system is proposed, the architecture of the software package is described. The presented system is implemented. An example of a scenario for managing a socio-economic system using the developed software package is given. The process of managing urban passenger transport is considered as an example. Thus, the study has implemented an approach that allows preserving the observability and manageability of the system and monitoring the process of managing the system, taking into account subject-object interaction. At the same time, the choice of actions to organize management and responsibility for the actions of the participants in the process lies with the participants themselves. The results of actions in the system that may lead to loss of manageability and impossibility of achieving the general goal (destruction of the system) are compensated by modifying the manage strategy without losing the structural coherence of the goal space. This ensures the very existence of the system in its environment.
