To the question of effective functioning organization of information subsystems of automated control systems for complex organizational-technical objects in conditions of external influences

For efficient operation of automated control systems for complex organizational-technical objects, you must provide certain information services to officials and automation systems. This is achieved through the functioning of the information subsystem of the automated control system with the required performance indicators. Information subsystem of the automated control system by providing information services to officials and automation systems helps them to make the right decisions in the control of organizational and technical systems. The functioning of the information subsystem is a complex process requiring analysis of indicators of its efficiency. You must imagine that being a complex system the information subsystem requires constant monitoring from the control system over current processes, which generates control actions on the basis of it. To control the operation of information subsystems defined procedures and processes of information services and parameters of the information subsystem are developed. One of the objectives of control of information subsystems of automated control systems for organizations and complex objects is the choice of those or other procedures in situations of a lack of information on proceeding in the components of an information subsystem processes. In this paper we consider the problem of ensuring the effective functioning of the information subsystem with the use of certain control procedures on the basis of known control methods of information systems and networks operation in terms of external influences. The solution of this problem should be the creation of control algorithms of information subsystems of automated control systems with external influences that should form the basis of software and hardware of control system operation of the information subsystems. Creating automated control systems for controlling operation of the information subsystems presumes planned specific control procedures, based on methods of control of submitting process of information services and the methods of settings control of the information subsystem. The main role of the information subsystem is the provision of information services to users of the automated system of control, especially those responsible for decision-making.
