ISSS based on the principle to timely identify the causes and prevent the transition of the normal mode in abnormal mode, system evaluation and forecasting of the destabilizing risk factors dynamics, permissible risk margin, providing accompaniment of CES functioning with the possibility of operative formation of sufficiently reasonable decision to prevent the accidents and the disasters during the operation of complex technical object. The proposed strategy of guaranteed security of CES ensures system prevention of the inoperability and the danger of the object functioning, allows for abnormal and emergency situations timely decision making to change the mode of object operating. The base of the algorithm to control by the safety and the survivability on functioning CES in the abnormal situations is the diagnostics block, which proposed in the form of technical diagnostics information platform. Forecasting of the destabilizing risk factors dynamics is based on the functional dependencies restored on discrete samples given in real time. Indicators of the quality and efficiency of the technical diagnostics system are coordinated with those of the management system by the safety and the survivability that guarantees with the desired probability to prevent CES failures within the permissible risk margin for the different modes. The system of the technical diagnostics provides with the desired reliability timely detection, recognition and evaluation of the abnormal mode risk for a predicted time of CES operating, adjusting the security and survivability options to guarantee the timely elimination of the causes for the risk before the failure. There are given the examples of real CES functioning with timely detection of transition in abnormal and emergency modes of operation and return to normal mode.
