In this paper, an analysis of the problems and tasks arising from the design of situational awareness tools has been carried out. As a result, it has been established that the approaches in this area do not satisfy the requirements for modern intelligent tools for operational decision support for the reasons for the lack of methods and tools reflecting the dynamics of information processes and a distributed information processing architecture with weakly structured properties. The methods of operating and extracting knowledge from semistructured dynamic information are proposed.

Keywords: Situational awareness, poorly structured data, temporal information, dynamic structures, intellectual analysis

There is an expert system of electric transformer's diagnostics. This system can substitutes an expert and to choose the right decision in technical service and repairmen an electric transformer of railway electric substations. The article analyzes the modern methods of diagnostics and control the remaning life of electric transformer of railway electric substation. This analysis shows that all methods of diagnostics can determines the defect when it appeared. The task to create automated neural system for prediction the defect in the future. It is proposed to use expert system with the recurrent neural network, because it has ability to predict the time series.
