Abstract
Information systems are created in order to improve the management of complex organizational and technical facilities by providing managers with the required information for decision-making. The task of adaptive control of the information system of critical objects in the conditions of mass perturbations is a complex task (due to the multifunctionality of the information system) and expects using procedures applied depending on the state of the information system and the environment. In during of management an information system of critically important objects, it is necessary that goals of management was achieved that are reduced to the successful executing of the tasks of the automated control system of the department. To do this, it is necessary to match the values of the performance indicators required in the conditions of mass disturbances. In the work the problem of the decision of the problems connected with the introduction of the centralized management of the information system is solved. The management process includes the steps: obtaining information on the behavior of the information system, analyzing the information obtained, developing a solution and implementing the decision, implementing control actions on all management objects (all components of the information system, their management systems and equipment). The introduction of centralized management in the information systems of critical facilities is hampered by the heterogeneity of the information and telecommunication technologies and types of equipment used, including the control systems themselves, and standard management protocols, which leads to a number of additional problems: interruptions in information flows, slowdown in production processes control commands and increase the probability of errors. The paper considers a generalized control scheme for the information system, depending on the state of its components and parameter values.
Keywords: information system, critically important object, mass disturbances, vector control, information flow.
