Specifics of cause-and-effect relations in technological systems

The features of cause-effect-relationships in the technological systems which are described by the mathematical models are considered. It is shown that except real factors in the definite conditions in the systems appear the virtual factors capable to influence essential the systems functioning. Besides virtual the hidden factors making difficult the system behavior may appear in the systems. It is shown that taking into account these factors increases the decisions adequacy in monitoring the system in the concrete situation.
