Criteria are proved for the finiteness of exponential moments of the first passage times, the number of visits and the last exit times for standard random walks. An algorithm is introduced and investigated for calculating the average time of processing in stochastic Johnson's problem. For branching processes with immigration closed to critical approximate diffusion processes are constructed; distribution of additive functionals is found. For many - dimensional service processes in stochastic networks with different sorts of nodes and retrial calls functional limit theorems are proved. An recurrent scheme of parameter estimate for linear models taking account of additional a priori information is worked out. A security system of on - line access to structural elements of the medium "OMEGA" is constructed. On the basis of "OMEGA" the first version of courses of distant training "Econometrics" .
