The consideration of irreversible stochastic transitions (IST) in complex stochastic systems based on the most general probabilistic formalism is performed. The key quality, transition probability per unit time, alpha , is strictly introduced without referring to the conventional approach to the IST description. The expressions obtained for transition probabilities and average transition expectation time, ( tau ), allow one to take into account the influence of interactions between objects undergoing IST and external impacts on probabilities of transitions. The violation of common postulates alpha =1/( tau )=constant, as well as of the simple exponential kinetic law for A to B transitions is demonstrated. These postulates are shown to follow from the general consideration performed as a special particular case. The evaluation of statistical characteristics of various complex systems containing objects undergoing IST by means of the approach developed is demonstrated on two model problems.
