The parallel semi-Markov processes in objects group control tasks

Functioning of complex objects, controlled with computer, is investigates. It id shown, that the abstract analogue of every control loop is the ordinary semi-Markov process. Such abstraction is insufficient for analytical modeling the object as a whole, this is why for the description of synchronizing processes it is necessary to have more complex model, which may be obtained by means integration of ordinary processes into complex semi-Markov processes. For determining of the abstraction the term “functional state”, as all possible combination of structural states is introduced. The method of calculation of complex process semi-Markov matrix elements is proposed. It is shown, how may be evaluated time intervals of wandering through complex semi-Markov process.
