Managerial issues of IT-specialist trainingConventional approach to IT-specialist training in high school environment is hardly to be considered a market compliant nowadays. A team of high professionals working in Computer Science sand Informational Technologies faculty and Computer Centre of Saratov State Socio-Economical University elaborated the IT-specialist training framework platform. The system architecture basics and administrative solutions are described.

Constructing a heat map based on the point data of the application user’s activityIncreasing complexity of software products also increases the demands on their usability. The article
focuses on the software product’s usability evaluation based on the user’s activity data. There are
different types of user’s activity data and visualization methods for them, the choice of which depends
on the data composition and specificity. One of the most popular is a point data, such as mouse clicks
and movements. The commonly used visualization method for point data is a heat map — graphical
representation of data where the individual values contained in a matrix are represented as colors.
Authors suggest using the heat map as a mathematical model of the user’s activity, what allows formalizing
the user’s interaction with the software interface. However, there are no formal methods, described
in scientific sources, for constructing heat maps based on the point data of the user’s activity.
Authors propose the formal method for constructing such kind of heat maps. The proposed method allows
constructing heat map taking into account data density and expert-defined parameters to achieve
the desired clarity of visualization. In addition, described method was implemented in free software.

The mathematical models and algorithms of operational control for equipment TPPThis treatise about the developing a mathematical model and algorithm selection to pick a set of
measures for the ascertainment of a specific technical and economic regime TPP equipment in real-time
using a formal mode. The formal task was: to develop mathematical models and algorithms that allow
a formal way to select a set of activities used to select a certain technical and economic regime for a
TPP management system in real time. To select the arrangement that are used for solving problems of
choice regime of equipment was built instrument based on the use of abstract logic and AND/OR graph.
The conversion Karnaugh maps into AND/OR-graph helps to divide decision parent task into subsidiary
tasks, which is demonstrable for decision-makers. As a result, an algorithm for processing three
generalized scenarios was proposed, which is implemented by an information system for aggregating
and analyzing technical and economic indicators and in which it is possible to implement such an algorithm.
The use of such an approach will reduce costs for expensive experts, distribute responsibilities,
enable operational personnel of TPPs to accumulate, edit and aggregate the knowledge of various
specialists, leading to improved quality of production and financial planning of generating companies.
