The analysis methods of quality control on production 3D- printer for selective laser sintering technology of special products via the sizes of which we can estimate the geometric parameters and via an additional control system we can high up their quality in real time. Increasing demands for precision measurement raises new problems of optimization of mathematical models of measuring  transformations, and adequate processing of experimental data.

This article describes the features of classification methods and technologies, analytics Big data. Described group of methods and technologies, analytics Big data that are graded according to the functional relationships and formal model of information technology. The problem of the definition of ontology concepts analytics Big data.

The aim is the development of social networking Web portal for building not only social activities and ties, but also for the development and promotion of active lifestyle among people at all ages and status. The key objectives of the information system development through building of an objective tree have been identified. UML modeling of the system was fulfilled by building of diagrams such as: USE CASE, SEQUENCE, STATECHART, DEPLOYMENT, also the problem and tasks have been set.

Correlation information, apart from the possibility, and often the need for its application directly in mathematical processing, contains a number of other valuable data: the degree of influence of individual factors on the result of measurements, the presence of systematic errors, the course of time, etc. Autocorrelation analysis, as part of the overall correlation , allows us to evaluate the correlation between the components of the vector of measurement results.

Analysis of the advantages and disadvantages of triangulation and trilateration methods has been done in many works [3-5, 8, 9]. These studies are mainly based on the analysis of networks of a typical design. And the programs of observations in such networks for both methods have the same geometric configuration. The obtained conclusions are valid for geodetic networks with a geometrically localized program of observations. In particular, it can be state geodetic networks, or networks created in heavily built-up areas.

The article analyzes the scientific views regarding legal and regulatory framework to ensure the economic security of Ukraine. Analyzes the legal regulation in the sphere of economic security, determined objectively predefined set of social relations aimed at ensuring protection from threats to the national economy. Revealed major problems of economic security of the state and proposals for improving legal security areas investigated.

The thesis presents the analysis of water losses in the water supply system of Sanok in the years 2007 – 2011, on the basis of the data received from the Municipal Enterprise in Sanok. Calculated ratios of unit rates of water losses and indicators recommended by the International Water Association – IWA. The calculated rates for losses are comparable to the results obtained in other Polish water supply systems.

In the paper are presented the results of diagnostics, tests of materials, numerical modelling and static analysis of the current state of the bearing steel structure of the hall after a fire and design of the actions for the repair of the damaged steel structural members.

It was grounded the importance of key performance indicators in the system of modern
enterprise management. It was analyzed the scientific approaches in estimating and analyzing
effectiveness activity of enterprise. According to the results of analysis of different scientists’
researches in subject field in was notioned the ambivalent character of enterprise performance
indicators, used in different scientific issues. It was pointed out the changes, that happened in
the theories of effectiveness and efficiency.
