The Smart City concept, which appears at the confluence of two modern mega-trends of urbanization and digital revolution, essentially rests on digital technologies which allow managing processes of the city life. A smart city obtains data from various sources, derives information from them and converts the information to knowledge, which is used in decision making. The DIKW model shows, that it may be sensible to distinguish the notions of data, information, and knowledge. Black & Veatch company’s 3M model of a smart city is based on the concept of, «measuring, moving and managing» data. The model reflects fundamental stages of urban environment data handling. The paper points to three essential digital technologies, which play a significant part in implementation of ICT & Data infrastructure in a smart city. They are broadband networks, internet of things and big data

There are considered approaches to mining association rules of hybrid intelligence systems. A well-known algorithm for mining association rules is the Apriori algorithm, it can be used to process large items of quantitative values. The article presents modern methods of fuzzy data mining: with predefined membership functions, Aprior-based algorithms provide an easy way to analyze and describe the fuzzy association rules. FP-tree-based algorithms are particularly suitable to work with big data. Some types of fuzzy genetic algorithms are considered in detail, allowing to find both membership functions and fuzzy association rules.

The questions of decision-making are considered at the development of a complex tourist product, which includes places of leisure and recreation, relocations, places of residence and others. The multicriteria problem of choosing the optimal variant of the tour with the given criteria and user ratings has been set and solved. The proposed model can be used to build a decision support system for the development of tours around Russia.

The growing interest in travel around Russia and the lack of information support determine the relevance of developing decision support systems in the tourism industry. The work presents the results of information modeling of such a system that allows, based on monitoring of thematic Internet resources, to create a database of tourist sites and events, places of residence, transport routes and based on user estimates, form a completed tourist product that appropriate the requirements. The obtained models are the basis for the development of the software environment.

The work is devoted to the further extension of the Analytic Hierarchy Process (AHP). In its classic version, the hierarchical structure of goals, factors, criteria and alternatives is set in advance. The calculation of priorities at each level is based on the matrices of paired comparisons obtained by the expert method. The paper proposes to build a table of the hierarchy of priorities directly by using measurements carried out in the target audience. For this purpose on the basis of the primary data received by questioning, the consecutive hierarchical factorization developed earlier by authors is carried out. As a result of this procedure, the full hierarchical structure of goals, factors and criteria is revealed, starting with the primary features and ending with the integral target factor of the whole task. In addition, for each identified level determined by the matrix of factor loadings, allowing to calculate the local priorities of the factors. Their global priorities with respect to the goals defined on the basis of the principle of the synthesis of the AHP. The proposed technique is illustrated by the example of the analysis of students ' perception of the educational process, which was conducted on the basis of extensive questionnaires in 2015 in SFEDU.

The article deals with the question of injury to the enterprise "Rostvertol" for the period from 1999 to 2010. Discusses some indicators of the status of labour conditions and safety of employees. The analysis of data on the number of injured in accidents at work by gender, age and length of service in the organization. As well as the number of injured by type of accident and by profession. Analyzed data on the number of victims for reasons that have led to an accident in the workplace. On the basis of the study there are several main reasons. Such as the unsatisfactory organization of work and production violation of labor discipline.

This paper describes the smart city definitions and expresses a view that smart city infrastructure consists of digital technologies and information and communication technologies. We make the point that the terms Urban Digitality, Urban Computing and Urban Informatics are used to describe smart city’s underlying digital technologies in English language scientific literature. The three-step American smart city model is analyzed. The model supposes a city to collect information about itself using sensors and other devices on the first stage. On the second stage collected data is transferred by means of wired and wireless networks to be analyzed on the third stage for better understanding of the present situation and what may happen in the future. Having found that the digital technologies of internet of things, social networks and mobility correspond to the stage of «Collect», so as the technology of cloud computing is brought into correlation with the stage of «Communicate» and, finally, that the digital technologies of big data and analytics are compared to the stage of «Crunch», we reveal the substance of smart city technological base.

Smart cities development initiatives, which become the response on growing urbanization, rise the problem of smart city digital technologies study. Digital revolution grows stronger, so it makes possible to use digital information and communication technologies in city management and allows rise of life quality. The digital revolution modern stage is characterized by the technologies combination of the third digital platform which is briefly referred to as SMAC, on the first English letters of social networks, mobility, analytics and cloud computing. This paper describes IBM’s smart city model, which consists of three stages: instrumentation, interconnection and intelligence. Instrumentation means that the workings of the system are turned into data points and the system is made measurable. Interconnection means that different parts of a core system can interact with each other, turning data into information. Intelligence refers to the ability to use the created information in decision making processes. We declare that the third digital platform technologies having been correlated with the model stages could be considered as the digital technologies of a smart city.
