The purpose of the article is the enhancement of the instruments for automation of the qualitative research of the dynamic system and forecasting values of the parameters, which characterize organization activities in the economy (particularly in the field of management of housing and communal services). In this article, the problem of automation of the analysis of the phase trajectory of the dynamic system is solved (organization of management of housing and communal services), using the qualitative theory of dynamic systems. The research is relevant due to the insufficient level of automation of qualitative research of dynamic systems in the economy with the economic interpretation of research results. Methods of qualitative theory of dynamic systems, which are used, allow forecasting the state of the dynamic system without numerical simulation (for example, integrating differential system, which is a model of the dynamic system). In the article is presented technique, in accordance with research of the phase trajectory of the dynamic system using the software application, was conducted. Types of phase points in the phase plane in accordance with character of behavior of the phase trajectory plane in the neighborhood of the projection of the phase point were identified. By the example of the phase trajectory analysis, which characterizes activity of organization of management of housing and communal services, opportunities of the software application, building of projection of the phase trajectory into the three planes occurs. It was identified that in the phase planes equilibrium states as «stable node» and «stable focus» are missing, but there are equilibrium states such as «unstable node», «unstable focus» and «saddle». The example of detection of the «field of attraction» of the phase trajectory in phase plane is given. Types of «fields of attraction» were identified and economic interpretation for the «fields of attraction» was given. The main directions for the enhancement of the developed software application functionality are formulated. The materials of the article present the practical value for the experts, who are forecasting state of the organization in economy, and particularly in the housing and communal services.

In this paper the analysis of a general statement of the optimization problem associated with the choice of managerial decisions. The development of techniques that allow a static analysis of the organizational structure of enterprises involving graph approach and the method of structural matrices is carried out. A graph describing information linkages is represented by the adjacency matrix. The methodology allocates several stages: definition of the state vector of the system outputs are defined in every structural unit; and then identifies interrelationships that exist among the subsystems; further analysis of the system is determined by what exists detailing the directions of each of the subsystems. As the main three kinds of characteristics in the organizational system: the tasks performed in each of the divisions; communications that occur between tasks and have different intensity; the reasons that caused a certain type of communications. Built a matrix that contains the characteristics of relationships among named tasks performed in the departments of organizational structure. It is shown how the linear programming problem is solved on the basis of the approximate method. It is noted that the approximate method is quite easy to implement. The optimal task plan is obtained, with no limit on corporate resources.
Keywords: : parallel sorting, algorithm, data, processor.
THE METHODS OF PROCESSING MEDICAL DATA
In the paper we shall review the possibility of building an outsourcing company that is associated with the processing of sound and radio signals. The analysis of outsourcing types is given. The main problems that arise when developing governance structures in the company are shown, the analysis of the characteristics of the forms of control are considered: the linear organizational structure, functional organization structure, functional linear structure, linear organizational structure, with functions cross-divisional management structure and organizational structure by region, product structure, organizational structure focused on the consumer. The scheme of an outsourcing company for processing audio and radio signals is given.
Keywords: sound signals, radio signals, outsourcing, company, organization.
