The result of this study is the technique for system evaluation of real CES operating taking into account the margin of permissible risk. The proposed technique is directed to timely detection and elimination of the causes for situations, connected with a possible transition of CES into an inoperable mode as a distinguishing feature. The time interval is determined to implement the coordinated margin of permissible risk, taking into account the integral informedness index and an unavoidable threshold time limit. This time interval may be used for guaranteed prevention of the specified abnormal mode in order to maintain the necessary indicators values of complex engineering system functioning in the normal mode. The proposed technique is implemented using a water supply system as an example, where the water level in the reservoir and the water pressure at the water inlet of a technological object are used as indicators; the values of these indicators characterize the state of the system at each time instance during its operation. The values for the coordinated margin of permissible risk are received in time instants, which can be used to implement the guaranteed prevention of an abnormal situation for one indicator and an emergency situation for another.
