Control in Social and Economic Systems
Astract. The first part of the paper presents the new approach to developing of intelligent control systems of complex organizational structures. Existing problems, in particular, those connected with the huge dimension of systems, complexity of problems solved and uncertainty in the choice of effective operating parameters are studied. Effective methods for solution of such problems by example of the control system for vertically integrated organizational structure are offered.
Keywords: intelligent control systems, management of organizational structures, mathematical and software support for complex control systems.
Ougolnitsky G.A., Usov A.B. Control of Sustainable Development of Hierarchical Systems in Conditions of Corruption (pp. 19-26)
Astract. The mathematical formalization of the corruption phenomena in three-level control systems is given. The consideration is based on the example of water quality control systems.

Zavadsky V.K., Ivanov V.P., Kablova E.B., Clenovaya L.G. Methods and Ways of Formal Description of Incompleteness of Information in the Initial Data on Designing of On-Board Terminal Systems (pp. 71-77)
Astract. The paper considers two approaches to setting of the aprioristic information and the formal account of uncertainty of the aprioristic data for a class of terminal control systems. Under the first approach the stochastic model of Bayesian type system with partially unknown probability characteristics of stochastic disturbances is set. Under the second approach the family of system models ranged by complexity level is set for the control problems in which the order of the object equations and the class of stochastic disturbances are unknown.
Keywords: uncertainty of aprioristic data, terminal control, on-board systems.
