22. Guaranteed Safety Operation of Complex Engineering Systems

A system strategy to estimation of guaranteed survivability and safety operation of complex engineering systems (CES) is proposed. The strategy is based on timely and reliable detection, estimation, and forecast of risk factors and, on this basis, on timely elimination of the causes of abnormal situations before failures and other undesirable consequences occur. The principles that underlie the strategy of the guaranteed safety operation of CES provide a flexible approach to timely detection, recognition, forecast, and system diagnostic of risk factors and situations, to formulation and implementation of a rational decision in a practicable time within an irremovable time constraint. The system control of complex objects is realized. The essence of such control is a systemically coordinated evaluation and adjustment of the operational survivability and safety during the functioning process of an object. The diagnostic unit, which is the basis of a safety control algorithm for complex objects in abnormal situations, is developed as an information platform of engineering diagnostics. By force of systematic and continuous evaluation of critical parameters of object’s functioning in the real time mode, the reasons, which could potentially cause the object’ tolerance failure of the functioning in the normal mode, are timely revealed.
