Assessment of the probability of logic-dynamic situation occurrence.

There is presented the definition of logic-dynamic situation that is used in specifying the operation of hybrid dynamic systems, including hybrid control systems. The influence of random effects on the behavior of systems is discussed. The methods of estimating the probabilities of occurrence of situations based on estimates of the statistical characteristics of random processes are considered. There show how to use estimates of the probabilities for the control and decision support. The results of experimental research of methods under consideration are given.
