the analysis of the subject area shows the complexity of the project management in the areas of regional life security systems development due to large data streams and far-flung network of communications between them. Structural-logical scheme has been constructed in the form of a graph of possible system conditions. The scheme opens the full essence of data streams management in the projects of regional security systems development. The structure of interconnection inside the data streams set has been investigated. The structure of the information system of project management in the areas of regional security systems' development has been developed.

the article deals with information and technical support of the forest fire suppression process. The status update on the problem is considered. The necessity of using modern information decision-making systems in the process of forest fires suppression is substantiated. Improvement of the method of a decision support system constructing using MVC coding patterns is proposed.

In this paper, we present the results of modeling nonstationary oscillatory processes in rods consisting of an arbitrary number of pieces. When modeling oscillatory processes that occur in many technical objects (automotive shafts, rods) an important role is played by finding the amplitude and frequency of oscillations. Solving oscillatory problems is associated with various difficulties. Such difficulties are a consequence of the application of methods of operation calculus and methods of approximate calculations. The method of modeling of oscillatory processes offered in work is executed without application of operational methods and methods of approximate calculations. The method of oscillation process modeling proposed in this paper is a universal method. The work is based on the concept of quasi-derivatives. Applying the concept of quasi-derivatives helps to avoid the problem of multiplication of generalized functions. Analytical formulas for describing oscillatory processes in rods consisting of an arbitrary number of pieces are obtained. It can be applied in cases where pieces of rods consist of different materials, and also when in places of joints the masses are concentrated. The proposed method allows the use of computational software. An example of constructing eigenvalues and eigenfunctions for a rod consisting of two pieces is given.
