The thesis work is devoted to solving the following actual scientific problem: increasing the degree of completeness of presenting information on processes arising in the resource and social communication networks of a city with a large population size
based on the development of models of methods and information technologies to support decision making when providing information and technological services and facilities. The object of study: processes of supplying resources and forming facilities for providing
information services. The subject of study: models, methods and means of forming procedures for the information and technological support of processes of supplying resources and providing information services and facilities to residents and guests of a
large city. On the basis of the analysis of the current state of scientific research and development of information technologies used to support processes in resource and social communication networks of a city with a large population size, an information and
technological matrix was formed with the help of which the corresponding relation to the “Basic information technology classes” set of attributes and the information and technological components of the “smart city” concept was analyzed. The analysis and construction of prototypes of data hypercubes concerning urban resource and social communication networks were carried out, on the basis of which the
data warehouse structure was modeled. Classification and parameterization of multiple categories and attributes was carried out to describe processes in urban resource and social communication networks, which allowed, for the first time, to use IT OLAP on the basis of data hypercubes to develop information technology of complex multidimensional data analysis characterizing the course of the process of urban resource and social communication networks. Models of urban resource and social communication networks were developed, which, unlike the known ones, consider the complexity of network attributes. The method of event processing in city resource networks was developed, which, unlike the existing ones, consider the diverse nature of urban network resources. This, in turn, made it possible to form effective recommendations for promptly responding to changes in the state of resource networks and the interaction of consumers and municipal
administrations with groups of providers of relevant services. A method for selecting a group of “big data” analytical processing tools was developed using the original set of attributes. The method is based on the known hierarchy analysis method. The method of selection of information technology platform for analytical processing of urban data collections is developed based on the method of expert assessments, which is based on the procedure of pairwise comparisons of options. With the help of the above methods and
based on the multidimensional data analysis proposed in Section 2 of information technology, information technology was developed to support processes in urban resource and social communication networks, which is presented in the form of a technological
chain and corresponding activity diagrams. A common architecture of information technology platforms designed for the implementation of various types of information systems of a city, which integrally and systematically integrates all stages of information and technological support of processes that take place in urban resource and social communication networks, was designed. Based on the analysis of functional requirements, context diagrams and use case diagrams for information systems were developed, in which basic procedures of
information and technological support of processes arising in urban resource and social communication networks were implemented. The prototypes of the database of information and technological support of processes in resource and social communication networks of a “smart city” were designed. Prototypes of program-algorithm complexes that implement information technologies to support processes arising in resource and social communication networks of a city with a large population size were developed, and two complete information systems were formed. The above systems were implemented in municipal institutions to provide personalized recommendations to users with regards to resource usage modes, which in turn allows reducing the cost of municipal services consumed and optimize the load on urban resource networks.
